 This report focuses on automatic braking and other active safety systems on Nissan and Honda cars sold in Japan along with future plans. Both companies plan to adopt automatic braking and various other preventive safety systems on more models including mini vehicles and compact cars.

 In January 2015, Nissan announced that its automatic braking system, dubbed the Forward Emergency Braking System, will be available on nearly all Nissan vehicles including electric vehicles (EV) and commercial vehicles by March 2016. The Forward Emergency Braking System is offered in three different types; the millimeter-wave radar-based type available on the Fuga and Skyline, the camera-based type available on Teana, X- Trail, Serena and Note and the laser radar-based type available on mini vehicles.

 The all-new Honda Legend launched in February 2015 features an advanced driver-assistive system package, dubbed Honda Sensing that uses millimeter-wave radar and a monocular camera. The package contains eight active safety functions including six that are newly added to the safety systems on Honda cars. The package is available on a broad range of models including the Odyssey that was partially redesigned in January, the all-new Jade minivan launched in February, and the all-new Stepwgn being launched in April. The package details on the Odyssey and the Jade differs from that on the Legend.

 The availability of the safety systems is not limited to all-new models or fully redesigned models. Nissan and Honda plan to adopt automatic braking and other active safety systems on partially redesigned models as well at the earliest opportunity.

It will be available on the Leaf EV and commercial vehicles as well. This shows Nissan's corporate initiative to appeal "Nissan's innovative automatic braking technology" to the market.

Nissan: Automatic braking system to be available on nearly all vehicles by the end of March 2016

 In January 2015, Nissan announced that the Forward Emergency Braking System (automatic braking system) will be available on nearly all vehicle categories sold in Japan, including electric vehicles and commercial vehicles, by the end of March 2016. When the announcement was made, the system was available on six models including the Skyline, X-TRAIL, Serena, Note, Nissan Dayz and Nissan Dayz Roox. It is now available on two more models, the Fuga and the Teana, as of February.
 Nissan plans to commercialize its autonomous driving technology in stages by 2020. The company is expanding the availability of the Forward Emergency Braking System making full use of autonomous driving technologies, such as camera recognition and control automation, to deliver safety to its customers.

 Nissan's Forward Emergency Braking System is offered in three different types: the millimeter-wave radar-based type available on the Fuga and Skyline, the camera-based type available on Teana, X- Trail, Serena and Note and the laser radar-based type available on mini vehicles.

 The Fuga and the Skyline fitted with the millimeter-wave radar-based automatic braking system is also fitted with the predictive forward collision warning system capable of detecting the movement of not only the car directly ahead but also a vehicle traveling ahead of the preceding vehicle.

Nissan's three Forward Emergency Braking System types and Predictive Forward Collision Warning

Forward Emergency Braking (Millimeter-wave radar-based type)  When the millimeter-wave radar detects a potential collision with a preceding vehicle, the system alerts the driver using both a screen display and buzzer and generates a force that pushes the accelerator pedal up and smoothly applies partial braking to assist the driver in avoiding the collision. When the diver takes no action, the system will apply emergency braking to avoid or reduce the impact of collision.
 The millimeter-wave radar-based system locks on the car directly ahead when a car is traveling at approximately 5km/h or faster. It can avoid collision when a car is traveling at speeds up to 60km/h. It does not work with a parked car when the car is traveling at approximately 70km/h or faster.
Predictive Forward Collision Warning (PFCW)  The system uses advanced millimeter-wave radar to monitor the relative speed and distance of a vehicle directly ahead as well as another vehicle traveling in front of that car. It senses change in the road condition that may be obscured from the driver's view. When it judges that deceleration is required, the system warns the driver by screen display, buzzer and a retracting force on the seatbelt. This helps prevent a pile-up accident caused by a delayed braking.
 The PFCW is the world's-first system capable of sensing sudden braking by the vehicle traveling ahead of the preceding car.
Forward Emergency Braking (Camera-based type)  The system uses a front-mounted camera to detect a vehicle ahead or a pedestrian. It operates when a vehicle is traveling at speeds between 10km/h and 80km/h, and automatically stops or decelerates the car to avoid or reduce the damage of collision. It is capable of avoiding collision when the car is traveling at 30km/h or below. It does not work with a parked vehicle or pedestrian when the vehicle is traveling at 60km/h or faster.
Forward Emergency Braking
(Laser radar-based type)
 The system uses infrared laser radar to detect a vehicle ahead. When it judges a potential risk of collision, it alerts the driver with a warning light in the instrument cluster and buzzer. The system automatically applies emergency braking to avoid or reduce the damage of collision. It operates when a vehicle is traveling at speeds between approximately 5km/h and 30km/h and is capable of avoiding collision at speeds up to approximately 15km/h. The system also features emergency assist for pedal misapplication. When a car is traveling at low speed toward a wall or an obstacle and the driver steps on the accelerator pedal instead of the brake pedal, the system alerts the driver and automatically controls the engine power to mitigate damage of collision with the obstacle.

 

Other active safety systems on Nissan vehicles

 In addition to the Forward Emergency Braking System, a 360-degree view preventive safety technology is also available on Nissan vehicles. The Lane Departure Warning, Around View Monitor and Emergency Assist for pedal misapplication are available on many Nissan vehicles that were launched recently.

Other frontal safety features

Intelligent pedal  The system reduces the driver's burden when a car is traveling on the roads that require frequent acceleration and deceleration by assisting the driver in keeping distance to another vehicle ahead. When the car approaches the preceding vehicle and the driver releases the accelerator pedal, the system automatically applies partial braking to decelerate the car. If the driver keeps his or her foot on the accelerator pedal, the system generates a force that pushes the accelerator pedal up and smoothly applies partial braking to urge the driver to release the pedal.
Intelligent Cruise Control with low-speed follow
and navigation-cooperative
 The Intelligent Cruise Control available on the Fuga and Skyline has low-speed follow-capability and navigation-cooperative control function available over the entire speed range up to the maximum cruising speed set by the driver (approximately 40 to 100km/h). The system stops the car adaptively when the preceding vehicle stops. This reduces the driver's burden and makes driving more pleasant. The navigation-cooperative function controls deceleration based on the information about the curve ahead provided by the on-board navigation system.
High-Beam Assist  The High-Beam Assist detects oncoming vehicles, vehicles ahead and street lights and automatically switches between the high and low beams whichever is appropriate. The new system is adopted in Nissan's all-new Skyline.
Side safety features
Blind Spot Warning  The system uses side sensors mounted at rear right and left of the vehicle to detect other vehicles traveling in the adjacent lanes diagonally behind. The driver is alerted of the presence of such vehicles by an indicator located on the side mirror. When the driver starts to change lanes in that condition, the driver is alerted by the indicator and buzzer.
Blind Spot Intervention  The Blind Spot Intervention has been added to the system. It briefly generates a force that puts the car back in the lane to assist the driver in preventing collision with another vehicle in the adjacent lane. The new function is adopted in Nissan's all-new Skyline.
Lane Departure Warning/
Lane Departure Intervention
 When the car has strayed from its intended lane, the Lane Departure Warning alerts the driver by buzzer and screen display. The Lane Departure Prevention controls the individual brake actuator pressure to generate a force that would put the car back in the lane to assist the driver in steering the car back to the lane.
Rear safety features
Back-up Collision Intervention  The system uses side sensors located at rear right and left and rear-mounted sonar to detect another vehicle crossing behind the car and alerts the driver to take necessary action. If the driver continues backing up in that situation, it generates a force that pushes the accelerator pedal up and smoothly applies partial braking to physically warn the driver to avoid collision with an approaching vehicle. The system is adopted in Nissan's all-new Skyline.
360-degree view safety features
Around View Monitor with park assist  The images captured from four cameras are sent to an image processing unit and the system displays front, side and rear views as well as a top view that gives a virtual surround view of the vehicle. These views assist the driver with better awareness of the car's surroundings and makes parking easier.
 A couple of options can be combined with the system depending on the vehicle on which it is fitted. The Moving Object Detection visually and audibly alerts the driver of a moving object when the vehicle is parked or starting. The Park Assist visually and audibly gives best parking instructions such as backing-up start position and steering angle during garage parking or parallel parking.
Emergency Assist for pedal misapplication  The system uses front- and rear-mounted sonar to detect the distance between the car and an obstacle. When a vehicle is moving forward or backing at 15km/h or below as in parking and the driver mistakenly steps on the accelerator pedal instead of the brake pedal, the system automatically restricts the engine power and brakes to assist the driver in preventing excessive acceleration and mitigating damage of collision with the obstacle.

Honda Sensing new safety system available starting from 2015

 In February 2015, Honda launched the all-new Legend fitted with a full package of a new driver-assistive system, Honda Sensing. The system consists of two types of sensors with different characteristics, millimeter-wave radar and a monocular camera. It is capable of activating eight safety functions including Collision Mitigation Brake System (CMBS) and Adaptive Cruise Control (ACC) with low-speed control capability (six of the eight functions were added to the existing driver-assistive system). One of the newly added functions is the world-first Pedestrian Collision Mitigation Steering System. When a potential collision with a pedestrian is detected, it turns the steering wheel toward the other direction to facilitate the driver's collision avoidance effort.

 In addition to the millimeter-wave radar and a monocular camera, the all-new Legend is equipped with fish-eye lens CMOS camera, ultrasonic sensor, and microwave radar. The Legend features multi-view camera system and many other safety devices.

 

Honda Sensing also available on Odyssey, Jade, and next Stepwgn

 Honda Sensing is fitted in the Odyssey that was partially redesigned in January 2015 and the all-new Jade minivan that was launched in February. However, the system varies in function between Honda Sensing on the Legend and those fitted on the Odyssey and Jade. The Pedestrian Collision Mitigation Steering function is not available on the Odyssey and Jade and their ACC functions do not have the low-speed control capability. Honda has announced that Honda Sensing will be made available on the all-new Stepwgn slated for launch at the end of April 2015.

Honda Sensing available on the Legend, Odyssey and Jade

 The system consists of two types of sensors with different characteristics, millimeter-wave radar located in the front grille and a monocular camera mounted at the inner top of the windshield. It is fitted on the all-new Legend that was launched in February 2015. It is also available on the Odyssey and Jade.
 With further improvement in performance, the aperture angle of the millimeter-wave radar was increased from 20 to 30 degrees. As a result, the system can now detect pedestrians that were considered difficult to detect because of the low reflectance. The single-lens camera is capable of identifying the attributes and sizes of pedestrians and other objects within approximately 60m ahead, achieving recognition with improved accuracy.

 

Eight functions Full Honda Sensing package on the Legend
Collision Mitigation Braking System (CMBS)  The system uses millimeter-wave radar and a monocular camera to detect the position and speed of an object and identifies the preceding and oncoming vehicles as well as pedestrians. When a potential collision is detected, the system audibly and visually alerts the driver along with vibrations on the accelerator pedal. If the driver takes no action, the system gives a sensory warning to the driver by automatically applying partial braking force and light retracting force on the driver's seatbelt. If the distance with an object gets shorter, the system automatically applies full braking force and retracting force on the driver's seatbelt to assist in avoiding and reducing the damage of collision.
 The system functions when traveling at approximately 5km/h or faster and the relative speed with the preceding or oncoming vehicle or a pedestrian is approximately 5km/h or faster. It functions with an oncoming vehicle or a pedestrian when the car is traveling at approximately 80km/h or below.
Road Departure Mitigation System (RDM)  The monocular camera is used to detect the lane markers. If the vehicle starts to stray from the lane, the system alerts the driver with vibrations on the steering wheel and a warning display. It also applies corrective steering input to bring the vehicle back in the lane. If the system judges that the vehicle is straying too far off, it will apply braking force to prevent the vehicle from driving off the road. The system functions when a vehicle is traveling at approximately 60km/h or faster.
The world's first Pedestrian Collision Mitigation Steering System  The system uses millimeter-wave radar and monocular camera to detect roadside pedestrians and lane markers. When the vehicle starts to stray off the lane toward a pedestrian, the system gives audio and visual warning to the driver and controls the steering toward the safer side to urge the driver to take corrective action. The system functions when a vehicle is traveling at approximately 10km/h to 40km/h. The system is designed to assist the driver in avoiding a collision and is not intended to perform steering for the driver.
Lane Keeping Assist System (LKAS)  The LKAS uses a single-lens camera to detect lane markers. To reduce the driver's burden, the system assists a vehicle in steering to stay in the center of the lane while traveling on highways. It functions when a vehicle is traveling at 65km/h or faster. The system is disengaged while the driver's hands are off the steering wheel.
Adaptive Cruise Control (ACC) System with Low-speed Follow  The ACC system uses millimeter-wave radar and the monocular camera to detect the distance to and relative speed with the preceding vehicle. It controls the accelerator and brakes to keep appropriate distance. The low-speed adaptive control limit has been expanded to 0km/h so that the driver's burden is reduced while a vehicle is traveling on congested highways.
 The system functions when a vehicle is traveling at 0 to approximately 100km/h and may be used on highways without sharp curves that require frequent acceleration and deceleration.
Traffic Sign Recognition  The monocular camera is used to detect road signs (speed limits, no bulging, stop and no entry). The system calls the driver's attention to road signs by displaying the detected signs on the Multi-Information Display or Head-Up Display. The Stop and No Entry signs are displayed when traveling at approximately 60km/h or below.
False Start Prevention Function  The millimeter-wave radar detects a preceding vehicle or obstacles directly ahead when a vehicle is stopped or traveling at approximately 10km/h or below. If the driver presses the accelerator pedal suddenly in that situation, the system restricts the engine or motor acceleration for up to 4 seconds while giving audio and visual warnings to the driver and vibrations to the steering wheel.
Lead Car Departure Notification System  When the millimeter-wave radar detects another vehicle within 10m ahead to start off, the system gives audio and visual alert to the driver.

(Note) Six of the eight safety systems above, other than the CMBS and LKAS, are newly-adopted functions.

 

Other preventive safety systems on the all-new Legend

Blind Spot Information System  The microwave radar mounted on rear right and left bumpers are used to detect another vehicle traveling diagonally behind or in parallel. The system supports the driver when changing lanes by providing the information about the presence of other vehicles.
Surround-View Camera System  The fish-eye lens CMOS cameras mounted at front, sides and rear of the vehicle are used to display the front blind view, right and left side views, rear view as well as ground view (video image as seen from above the vehicle) in the navigation screen. This reduces the blind spots and makes it easier to park a car. The system functions when a vehicle is traveling at 12km/h or below (the screen returns to navigation when the speed rises above 15km/h).
Back-up Collision Prevention  When backing up from the garage, the system uses the microwave radar to detect other cars approaching from right or left, and displays them and their direction in the navigation screen.
Parking sensor system  The system uses six ultrasonic sensors (2 in front, 4 in rear) to detect obstacles in the area and warns the driver with a display in the navigation screen and sound depending on the distance to such obstacles.
High-Beam Support System  A special CMOS sensor mounted behind the rear-view mirror is used to detect the taillight of the preceding vehicle and headlights of the oncoming vehicle. When a preceding or oncoming vehicle is detected, the system automatically switches to low beams. When no vehicles are detected, it automatically switches back to high beams to maintain good visibility.

Honda: City-Brake Active System available on compact cars and mini vehicles

 Honda developed City-Brake Active System for scanning the road ahead using laser radar mounted behind the windshield. The system has been adopted on the all-new Fit and Vezel launched in the second half of 2013, the all-new N-Wgn launched in November, and the N-Box partially redesigned in December. The "Anshin Package (peace-of-mind package" consisting of the City-Brake Active System, side curtain airbags and side airbags is either standard or optionally available depending on the vehicle type.

City-Brake Active System

 The system functions when it detects a potential collision with a vehicle ahead when a vehicle is traveling at approximately 5km/h to 30km/h. It automatically stops or decelerates the car to avoid or reduce damage of collision.
 The system also has False Start Prevention function. When the driver presses the accelerator pedal mistakenly while the vehicle is traveling at approximately 10km/h or below and there is a vehicle ahead, the system restricts the engine power to prevent sharp starting and reduce damage of possible collision.
