<Highlights>
Exhibits are mainly those presented in the paper session held at the same time in such fields as environment, safety, material and air-conditioning.
[Environment]
Common Rail Technology:
(Second-generation 180MPa Piezo Common Rail System)
Based on the second-generation solenoid common rail system mass-produced in 2002, Denso developed the world's first 180MPa common rail system with highly responsive piezo actuated fuel injectors. Installed on Avensis of Toyota Europe in April 2005.
The newly developed piezo-actuated fuel injector mainly is comprised of an injector body, piezo-actuator, displacement magnification unit (that magnifies displacement in order for it to be sent to the control valve), a control valve, and a nozzle. By enhancing nozzle speed, injection time was reduced by 7.6% and the pilot injection intervals was reduced by 75% while the injection features improved.
[Safety/ITS]
Sensing System
Denso is planning to launch a system that can detect vehicles ahead and white lines through "fusion". The system fuses objects as needed so millimeter wave radar sensors, laser sensors, and image sensors can accurately detect the objects. Each sensor detects road conditions ahead (vehicles and white lines) and makes convenient drive-assist systems a reality. These include PCS, LKA, and ACC. Actual commercial use will start in two or three years.
Denso is developing recognition systems (based on only laser sensors) that can detect white lines, pedestrians, and vehicles, putting its expertise in the area of wide-angle and high resolution to use.
[Materials]
New Material Development
-The Company identified the trigger that causes long-glass-fiber reinforced polypropylene to self-destruct due to repeated cold-hot cycles. This reinforced polypropylene is used as a material for front end module (FEM) frames. Denso conducted thorough testing of material combinations to develop non-self-destructive, high-strength, materials appropriate for use as FEM material and which demonstrate long product-lives .
>>>Technical Information 1 /Technical Information 2
[Air Conditioning]
Pollen Eliminating Air-Conditioner
-The Company developed an automotive air-conditioner that can eliminate any pollens in the air around the occupants' faces. This air conditioner quickly eliminates pollen that is both unavoidably carried into vehicle by the occupants and that is forced into in the vehicle naturally when it is moving. This air conditioner is being equipped on the Toyota Vitz launched in 2005.
>>>Technical Information Cabin Air Filter (with pollen eliminating function )
Tokyo Motor Show 2005
Among the Company's four corporate divisions, namely safety, environment, comfort and convenience, focus was placed on safety technology, with sensing systems being exhibited; and on environmental technology, with hybrid and common rail systems exhibited.
Safety
The Company displayed various areas of technology such as assistance systems that enable driver recognition and vehicle self-maneuvering. The Company hopes to create a "collision-free vehicle".
<Sensing Systems>
*This technology provides safer and more comfortable environment.

(Example)
*Millimeter-wave Radar Sensor x Vision Sensor : A sensing system to recognize the shape, size, and type of object.
*Technology that monitor drivers
Driver Assistant System (a conceptual display):
-This conceptual display explained devices capable of (1) achieving facial recognition, (2) detecting whether drivers' eyes are blinking or remaining closed, and (3) taking electrocardiographs (a first in the world).
1.In facial recognition, a picture of the driver's face is taken through the use of a camera, and then the image is processed.
2. The ability to detect whether eyes are blinking or remaining closed is made possible by processing an image taken of the driver, and them measuring the eyelid aperture to detect cases when the driver is not paying attention to the road. Sleeping is one example. The Company has developed technology to learn more about what are the most optimal normal conditions. Also, the Company was successful in being able to the measure the speed that a person wearing glasses blinks.
3. Taking electrocardiographs checks drivers' heart beats through the use of electrodes installed in steering wheels. The results are then displayed on the car navigation monitor or transmitted to a remote location.
G-BOOK On-board Navigation System, Remote Security System (>>>Technical Information), AFS (>>>Technical Information) were also displayed.
Powertrain
<Common Rail System>
*1800-bar Diesel Common Rail System
The Company jointly developed with Toyota Motor the world's first 1800-bar diesel common rail system. This system is installed on the Toyota Avensis, launched in May 2005. The Company plans to supply this system to Ford Motor Europe before the end of 2005,
In 2002, the Company started producing a 1800-bar common rail system in Japan. This system still retains the lead as the world's largest-volume fuel injection system. In 2003 in Hungary and in 2004 in Thailand, the Company launched production of common rail parts.
Make Up of 1800-bar Common Rail System
This system is composed of the following: Supply Pum, Common Rail, Pressure Sensor, Injector, Electronic driver unit (EDU), Electronic control unit (ECU)
*2000-bar Diesel Common Rail System
At this motor show the Company announced its target to launch a 2000-bar system by 2007.
<Components for Hybrid Vehicles>
The Company developed components for hybrid vehicles such as a hybrid control computer, a battery-monitoring unit, a DC-DC converter, and an electric compressor. These components can not only meet the needs of today's larger hybrid vehicles but also have been made smaller, lighter and less expensive than conventional components. These components were introduced in Japan in March 2005 on the Toyota Harrier and Kluger hybrids.
1.hybrid control computer integrates control functions such as the hybrid system control, engine control, and battery control into one unit. The Company developed this system jointly with Toyota Motor.
2.battery-monitoring unit monitors the main battery, checking the voltage, current, and temperature, which were traditionally monitored by the battery ECU. The Company designed this battery-monitoring unit separately from the hybrid control computer because this unit needs to be installed close to the main battery. Optimizing the location where the unit is installed enables it to be significantly reduced in size.
3.A CC-DC converter reduces the high voltage (288V) of the main battery, the power source for the hybrid vehicle, to a low voltage range in which a support battery (12V) can be used. Also this converter operates devices such as lights, wipers and horns that run on 12V. This new converter is approximately 10% smaller than the conventional one but can generate a greater current from 100A, to 120A, thus it is able to respond to the electric power needs of the largest vehicles. To handle the increased current, the Company improved the converter's power elements by welding the mounting instead of soldering it. Customized integrated circuits reduce the area of the converter's circuit board by approximately 40%, contributing to a 10% reduction in size.
4.The Company developed a new part, an electric compressor, which is the first in the world to incorporate an inverter that drives the built-in monitor. This design reduces the compressor size by approximately 60% compared with conventional electric compressors and inverters. The Company miniaturized the inverter by using simplified circuits and a higher-density mounting with three-dimensional wirings. It is difficult to integrate compressors and inverters because conventional inverters are cooled by the engine's cooling system. To solve this problem, the Company developed a new cooling system using air conditioning refrigerant in the compressor, enabling the electric compressor and inverter to be integrated. The Company developed this compressor jointly with Toyota Industries Corp.
A Diesel Particulate Filter (DPF) was displayed as another example of powertrain technology.
Air Conditioning Systems
The Company displayed electric compressors and interior/exterior heat exchangers which make up the CO2 Air Conditioning System.
Small Motor
Please refer to the exhibits of ASMO
Tokyo Motor Show 2004
The Company developed a 1,800-bar common rail system which was introduced in the European market in June 2002. The Company's common rail system achieved a high injection pressure - 1,800 bar, the highest in the world - and five-time multiple injections at a high accuracy. This system comfortably cleared EURO4 emission regulations without a diesel particulate filter.
Production of the 1,800-bar diesel common rail system began at DENSO Manufacturing Hungary in 2003, and at Siam DENSO Manufacturing of Thailand this year.
In Europe, many vehicle models including the MPV and MAZDA6 of Mazda Motor Corporation, Avensis and Corolla of Toyota Motor Corporation, and Primera, Almera, Tino and X-Trail of Nissan Motor Co., Ltd. are equipped with this system. In Japan, Toyota's land cruiser Prado and Hilux Surf, commercial vehicles DUTRO and RANGER-PRO of Hino Motors, Ltd., and ELF and FORWARD of Isuzu Motors Limited are equipped with this system. The Hilux VIGO and Kijang Innova, both developed in the IMV Project Toyota started this year, also are equipped with the system. The Company plans to start supplying its common rail system to Ford in Europe in 2005.
Features and Advantages of 1,800-bar Common Rail System
The Company's common rail system can inject fuel at up to 1,800 bar, significantly reducing the concentration of PM in emission.
The high fuel injection pressure is generated by the supply pump, which is the lightest in the world for common rail systems.
The Company's new injectors can inject fuel at an interval of 0.4 milliseconds with a required small quantity -- only one cubic millimeter per one injection. The injectors allow the system to perform five injections during each combustion stroke. The five times multiple injections, having predetermined fuel quantities, reduce PM and NOx in emission, and achieve quietness equivalent to gasoline-powered engines.
Injection quantity deviation requirements from car manufacturers are increasingly severe, and the Company is striving to improve machining technology with micron-machining techniques to meet these requirements. Further, the Company developed a software compensation method for the new common rail system, which compensates for injection quantity deviations among the injectors. Specifically, by adopting a two-dimensional code, each injector has a code that contains its own deviation. The engine ECU then reads deviations of the injectors during assembly and compensates for them. In addition, to keep the precise injection quantity of each injector, the Company developed software that allows only one cubic millimeter per one injection while maintaining a variation of 0.5 cubic millimeters or less during its operation. As a result, the system can keep performing injections with required small fuel quantities, at high accuracy during its operation.
Thanks to the 1,800-bar common rail system, engine torque is increased by 35%, engine power is increased by 24% and low idle noise is decreased by 6.5 dB with a 2.0-liter diesel engine, as compared with the Company's conventional model.
Development of Piezo Injectors
The Company is now developing additional advanced common rail technologies, including one which contains piezo injectors. Due to the quick response of the piezo injector, the Company experimentally confirmed a pilot interval of 0.1 milliseconds and improved injection rate characteristics. This feature will help to further reduce concentrations of harmful substances in emission and lower the noise of the diesel engine. Plans are on the table to start manufacturing piezo injectors for the 1,800 bar common rail system with multiple injections in 2005. The Company also is working to develop a 2,000-bar common rail system to increase fuel pressure.
The Company will continue to develop common rail systems to meet stricter worldwide emission regulations and produce cleaner emissions, and quieter and more powerful diesel engines.
Paris Motor Show 2004
-The Company is supplying components for the world's first adaptive cruise control (ACC) system that regulates speeds at rates from zero to 30 km/hr. Conventional ACC systems only regulate speeds 40 km/hr and higher. This system is now available on the Toyota Majesta in Japan.
-The ACC system monitors the distance between your vehicle and the vehicle ahead, regulates your speed, and decelerates your vehicle when necessary to maintain a safe distance between vehicles.
-In the low speed ACC system , the laser radar or laser LIDAR (light detection and ranging) detects and calculates the position of an object located ahead at a horizontal angle of plus or minus 18 degrees. Low speed ACC systems allow drivers to use the cruise control in high traffic areas, without having to continually brake and accelerate.
-The Company's laser LIDAR for the low speed ACC system has the following capabilities:
- Improved capability to distinguish between moving vehicles and stationary objects such as signs.
- Higher data processing capability to calculate the position of an object ahead, by using data collected from a wider horizontal area.
- Higher resolution detection of vehicle distance - plus or minus 0.6 meters or less - allowing the system to automatically stop your vehicle
-The Company has been supplying main components for the ACC system since 1996, including:
- Laser LIDAR, which detects and calculates the position of an object ahead.
- Vehicle distance electronic control unit (ECU), which determines if the object is a vehicle and calculates your vehicle's target acceleration.
- Engine ECU, which controls the vehicle speed based on the target acceleration.
Pre-collision System
-The Company developed the world's first pre-collision system with Toyota Motor Corporation for the Toyota Harrier, launched in February 2003. The pre-collision system now is available on the Lexus LS430 in North America, and will be introduced on the Lexus LS430 in Europe by the end of 2004.
-The pre-collision system identifies inevitable obstacles a split second prior to collision, automatically tightens passenger seatbelts, and activates a pre-collision brake system to reduce vehicle speed.
-The Company developed three key components for the system - a millimeter-wave radar; a pre-collision electronic control unit (ECU), and a seatbelt ECU. The millimeter-wave radar detects vehicles and obstacles ahead. The pre-collision ECU processes information gathered by the radar to determine if the vehicle will hit the obstacle, and then sends information regarding distance and relative speed of the obstacle in the form of signals to the seatbelt ECU and the brake system. Based on those signals, the seatbelt ECU retracts the seatbelt mechanism, and the brake system assists the braking mechanism. As a result, this system can reduce damage from collisions.
-The Company's millimeter-wave radar can detect obstacles over a horizontal plane with the world's widest angle, 20 degrees, and detection accuracy of 0.5 degrees.
-The pre-collision system installed on the Lexus LS430 functions not only as a pre-collision system but also as an Adaptive Cruise Control (ACC) system. When functioning as an ACC, the same millimeter-wave radar and ECU monitor the distance between a vehicle and the vehicle ahead and regulate vehicle speed.
Adaptive Front Lighting System (AFS)
-The Company developed the world's first intelligent adaptive front lighting system (AFS) with Toyota Motor Corporation and Koito Manufacturing Co., Ltd., for the Toyota Harrier, launched in Japan in February 2003. This system now is available on the Lexus LS430 and RX300 in Europe and the Lexus LS430 and RX330 in North America.
-The AFS redirects low-beam headlamp units individually in a horizontal direction in accordance with steering angle and vehicle speed. As a result, this system can improve visibility during night-time cornering, ensuring safer driving.
-For this system, the Company is supplying an AFS Electronics control unit (ECU) and a swivel motor. As a vehicle turns a corner, the AFS EUC calculates the swivel angle using steering angle and vehicle speed information, and controls the swivel motor to focus the low-beam headlamp units in the direction of the turn, illumination the road ahead at a wider angle. The AFS ECU also calculates vehicle incline using the vehicle height, and controls a leveling motor based on the incline to maintain the headlamp's vertical axis.
Mercury-free High-Intensity Discharge Headlamp System
-The Company has developed, along with Koito Manufacturing Co., Ltd., Royal Phillip Electronics, and Toyota Motor Corporation, the world's first mercury-free high-intensity discharge (HID) headlamp system. This system completely eliminates mercury from discharge lamps (bulbs). The HID headlamp system is installed on the Toyota Porte, launched in Japan in July.
-The HID headlamp system has a newly developed mercury-free discharge bulb, as well as a controller (ballast) that controls lighting of the discharge bulb. Koito Manufacturing and Phillip developed the mercury-free discharge bulb using a mercury substitute. The Company, along with Koito Manufacturing, developed the ballast for lighting the mercury-free discharge bulb. The mercury-free HID headlamp provides bright lighting and long bulb life equivalent to a conventional system.
-To control the lighting, the ballast was improved to apply increased initial operating wattage and operating current to the newly developed mercury-free bulb.
-To increase the switching frequency of the DC-DC converter and enhance the heat resistance of the ballast, the Company developed semiconductor power devices for the new ballast.
Electric Air Conditioning System for HEVs
-Since the 1990's, the Company, has closely worked with car manufacturers to develop components for those hybrid vehicles.
-In September 2003, the Company started supplying an electric air conditioning system for the Toyota Prius, which is now sold in Japan, Europe and North America.
-Using a newly developed electric compressor, the electric air conditioning system provides comfortable air conditioning even during "idle stops" (when the engine shuts down to save fuel and emissions). This maintains cabin comfort while significantly reducing fuel consumption.
-The electric compressor combines a scroll compressor and a DC brushless motor. Because of its optimized scroll form and advanced motor control technology, the compressor improves efficiency in compressing refrigerant and reduces noise, leading to higher performance and quieter operation.
-The electric air conditioning system, including the electric compressor and the Company's latest small and lightweight heat exchangers, is compact, providing more space in the vehicle and further improving fuel consumption.
-In 2004, the U.S. Environment Protection Agency awarded the air conditioning system its Climate Protection Award.
-The Company developed and applied the world's first carbon dioxide (CO2) car air conditioning system using CO2 as refrigerant for Toyota's fuel-cell hybrid vehicle launched in December 2002.
Bluetooth Wireless Technology for Car Navigation Systems
-The Company developed the world's first software that use Bluetooth wireless technology to wirelessly connect car navigation systems and cell phones. The Company began supplying an electronics multi-vision board using this technology for car navigation systems in August 2003.
-By wirelessly connecting the car navigation system and cell phone, calls can be dialed by using touch keys on the car navigation display. The microphone and speaker of the car navigation system are then used for phone calls. The driver can easily edit the information stored in the cell phone, such as addresses, on the car navigation display.
-This technology is now available on several models of Toyota Motor Corporation sold worldwide, including the Lexus LS430 (named Cersio in Japan), Lexus LX470 (named Land Cruiser in Japan), and the Prius.
-The Bluetooth wireless technology will allow the car navigation system to be connected to the Internet and provide web-based services to drivers.
-The Company was among the first in the industry to start developing car navigation systems in the 1980s, achieving a pioneering success in 1987 with the launch of a car navigation system using digitized map data stored in on-board CD-ROMs. In the year ended March 31, 2004, the Company sold 720,000 car navigation systems worldwide.
