2017/11/21

Summary

TOYOTA Concept-愛i
Toyota’s “Concept-i” equipped with Artificial Intelligence (AI)

  The 45th Tokyo Motor Show 2017 was held at Tokyo’s Big Sight exhibition center from October 25 to November 5, 2017 with the theme of BEYOND THE MOTOR to convey a sense of progression into the future. This report provides an overview of the Toyota exhibition.

  During Toyota’s press conference on opening day, Executive Vice President Didier Leroy introduced the Toyota theme of "Start Your Impossible" (attempting to achieve what seems impossible), emphasizing Toyota’s commitment to "Mobility for All" so that everyone can realize the freedom and joy of mobility. The GR Hybrid Sports and Tj Cruiser were in the center of the exhibit stand, to remind people that cars must be fun and are something to be enjoyed.

  Moreover, Toyota introduced the three technological areas it will focus on to enhance the value of its future product portfolio, using the concept vehicles on display at the Toyota exhibit. The first was its Concept-i series that uses artificial intelligence (AI) and connected car technology. Also, these technologies will enable the all-new Crown Concept to become the new standard for Japanese connected cars.

  The second area of focus was automated driving, a key technology to provide mobility to those who cannot enjoy it now and realize Toyota’s “Mobility for All” vision. Toyota plans to introduce systems for highways to the market in 2020 and for normal roads in the early 2020s. Highly autonomous driving level systems will likely be used in the Concept-i series.

  The third technological area was electrification. Undoubtedly, electric vehicles (EVs) will be a key solution in the near future and the Concept-i series uses an EV powertrain. The press conference also focused on clean mobility, and fuel cell vehicles, with Mr. Leroy stating that "We believe our solid-state battery technology can be a game-changer with the potential to dramatically improve driving range" by the early 2020s. Toyota is also continuing its efforts to develop fuel cell vehicle (FCV) technologies, as seen in the Toyota concept vehicles for the Fine-Comfort Ride premium FCV and Sora Fuel Cell Bus.

  At the Lexus booth, the LS+ Concept, which is equipped with the latest automated–driving technology that Lexus is aiming to deliver in the near future, made its world premiere. Lexus is working to realize automated driving technology at Level 4 (High) or Level 5 (Full). In addition, the Lexus booth included exhibits for the new LS model released in October and the Lexus LC that was released in March 2017.

"TOYOTA Concept-i" series: The future of mobility

The core value provided by the Concept-i series technology is to "understand the driver" (Toyota press release)

  Toyota described the Concept-i series technology as being part of Toyota’s vision for future mobility that uses AI to enable future cars to better understand, learn, and grow with the driver and become their partner. The Concept-i autonomous car was actually showcased earlier this year at CES in January, but more content was added to the concept at the Tokyo Motor Show and the series was expanded to include the Concept-i Ride and the Concept-i Walk. Toyota plans to conduct road tests of vehicles equipped with some of the concept car's functions in Japan around 2020.

  The Toyota Concept-i series concept is being designed to be well regarded in a new era in line with the concept of “more than a machine, a partner.” This will involve the vehicle better understanding the driver and growing together with them as an irreplaceable partner. The core technology common to the Concept-i series is one that understands people (LEARN) and applies AI to recognize emotions and estimate driver preferences. The AI Agent (LEARN) and automated driving technology combine to lead the driver to safety and provide peace of mind (PROTECT), leading to new Fun to Drive experiences (INSPIRE).

  An EV powertrain is used for the Concept-i series.




Concept-i technology that understands people (LEARN)

"Understanding people" technology (LEARN)   Concept-i measures emotion and alertness levels through a complicated process of reading the driver's expressions, actions, and tone of voice. It compares general information such as news on the web with information on individuals from social media activity, GPS information, conversation history in the car, and other sources, and estimates the driver's preferences based on topics that come up repeatedly.
  LEARN uses technologies such as deep learning for processes like measuring emotions and estimating preferences. It enables the Concept-i series to provide value innovation in the areas of safety and peace of mind (PROTECT) and new Fun to Drive experiences (INSPIRE).

"Safety and peace of mind" (PROTECT)

LEARN × Automated driving technology

  In addition to the car's external conditions, Concept-i measures the driver's condition using technology that understands people to monitors the reliability of the driver and the car. For example, if the car's reliability is high and car support is deemed necessary (e.g. situations where the driver is overcome by a dangerous or high-stress situation), Concept-i switches to automated driving. In line with Toyota's "Mobility Teammate Concept" for automated driving, which aims to both watch over and assist drivers as needed, Concept-i provides the occupants with safety and peace of mind.
  Furthermore, it supports the driver by stimulating the five senses, including vision, touch, and smell, depending on the driver's emotion, degree of fatigue, and level of alertness to rouse them into an alert state when they feel drowsy and helps calm them when they are experiencing elevated levels of stress.

New “Fun to Drive" (INSPIRE)

LEARN × Agent technology
  Concept-i engages in conversation based on the emotions and preferences of the driver. The car suggests topics of interest based on their mood to create a completely new style of two-way conversation. In addition, it creates an "Emotion Map" by periodically recording the driver's emotions and GPS data. By collecting data on individual emotions and using this information as big data, the TOYOTA Concept-i series can deliver fresh experiences by suggesting slight detours onto new, enjoyable routes.

Note: AI Agent technology supports the driver in carrying out the repetitive computational decisions required for safe operation of the vehicle. It enables a car to recognize, understand, judge, and take actions as if it were a human driver. This is made possible with technologies that partner the driver and car to accumulate and process big data and provide seamless mobility.



Toyota announces Concept-i Ride and Concept-i Walk

  Two models added to the Concept-i series.

  The Ride is a smaller sized vehicle that Toyota has designed for user-friendly city mobility. Suitable for both regular drivers and wheelchair users, the Concept-i Ride comes with gull-wing doors; an electric universal sliding seat; and a joystick that eliminates the steering wheel, accelerator and brake pedals. The vehicle supports safe and secure driving and is also expected to be used for ride sharing services.

  The Walk is a compact, three-wheeled personal mobility vehicle that takes up space the same amount of space as a pedestrian on foot. It does not require the use of specific clothing or footwear and is expected to be used for ride sharing services. Toyota is targeting the Concept-i Walk for use in traveling short distances such as walking around sightseeing spots.

Main features of the all-new Lexus LS:

GA-L (Global Architecture-Luxury) platform
A designed-to-be-driven innovative coupe silhouette   Application of the GA-L platform has resulted in a low, poised-to-pounce styling, while large-diameter tires create a commanding presence. To produce a daring coupe silhouette that sets the new LS apart from previous four-door sedans, Lexus employed a six-light cabin design that features three windows on each side of the vehicle for a total of six side windows.
Powertrain

Newly developed  3.5-liter,

twin-turbo V6 engine (LS 500)

  Lexus' first 3.5-liter, twin-turbo V6 engine is exceptionally quiet yet provides exhilarating acceleration based on its linear torque characteristics. Rapid combustion has been achieved by measures to improve air intake and strengthen airflow within the engine's combustion chambers. World-class thermal efficiency, made possible by combining the engine with high-efficiency twin turbochargers, results in high output and excellent fuel efficiency.
  The Direct Shift-10 AT provides exceptional rhythmic gear changes made possible through actively selecting the optimal gear by reading driver intention based on their inputs.

Multi-stage Hybrid System

(LS 500h)

  The Multi-stage Hybrid System is a breakthrough technology that combines stepped gears and the Lexus hybrid system newly developed for the LC 500h luxury coupe. It provides strong driving force from low speeds for powerful performance by controlling the output of both the high-revolution 3.5-liter V6 engine and the electric drive motor.
  Adjustments in engine revolutions faithfully in line with the intentions of the driver and highly responsive motor assist are made possible by 10-gear-change control regardless of the driving situation, creating a direct acceleration sensation perfectly linked to pedal operation.
New advanced active safety technology and advanced driving assist technology
New advanced active safety technology   In addition to the conventional Pre-Collision System, which supports collision prevention and damage reduction through alerts, the new LS is equipped with the world's first large, color HUD that specifies the locations of pedestrians for more-intuitive pedestrian alerts, and is equipped with Pre-collision Brake Assist, Pre-collision Braking, as well as with Active Steering Assist, which automatically controls steering and braking.
  Active Steering Assist determines when there is a high possibility of collision with a pedestrian in the lane of travel or with a continuous structure, such as a guardrail, and if the system also determines that it is difficult to avoid a collision with brake control alone but that it might be avoided with steering control, the system assists in collision prevention or damage reduction through automatic steering control in addition to activating an alert and applying the brakes.
Lexus CoDrive advanced driving assist technology that can lead to automated driving   Lexus CoDrive adds Lane Change Assist to the basic functions of Dynamic Radar Cruise Control and Lane Tracing Assist to provide steering support that is in line with the intentions of the driver and lane-changing support on highways or motor-vehicle-only roadways. By providing seamless driving support on roads with many curves or in traffic jams, Lexus CoDrive largely decreases driver burden.
  Lane Tracing Assist provides lane-keeping support by way of steering control when Adaptive Cruise Control is in operation. In addition to lane line detection by way of a camera, tracing of the path of the vehicle ahead enables assistance even when lane lines cannot be recognized, such as in low-speed driving in congestion when there is little distance to the preceding vehicle.
  Lane Change Assist, which uses driver manipulation of the turn signal as a cue to activate, supports lane changes by monitoring the surrounding road environment and, at the appropriate timing, controls steering, as well as acceleration and deceleration.


Technology exhibited at TOKYO CONNECTED LAB 2017

  Toyota introduced the following technology using interactive displays at the TOKYO CONNECTED LAB 2017 exhibition held on the 4th floor of the West Exhibition Hall at the 2017 Tokyo Motor Show.

  • SmartDeviceLink (SDL): SDL is an open-source standard promoted by Toyota that connects smartphone apps together with automobiles. Users can operate apps within the vehicle through voice-recognition functionality and the automobile's control panels. Toyota and Ford established a SDL consortium in January 2017 that includes automakers such as Subaru, Mazda, and Suzuki, as well as entertainment console suppliers such as Panasonic and Pioneer. The consortium competes with Apple's Car Play and Google's Android Auto.
  • LINE's Clova AI platform: Clova is a LINE’S cloud AI platform with voice-recognition functionality. In June 2017, Toyota and LINE started to explore potential business opportunities using LINE’s AI platform Clova and SDL.
      By tapping the voice recognition button on the steering wheel of the demonstration vehicle, visitors were able to experience first-hand the ability to read new LINE messages and access music, weather forecasts, news, and more.
  • TransLog data-transmission drive recorder: As an outcome of ongoing verification testing being conducted with the Japan Federation of Hire-Taxi Associations since April 2017, Toyota plans to start a service that provides lane-specific traffic-congestion information to its TC Smartphone Navigation smartphone app. The information is to be generated by analyzing driving video and vehicle data collected from Toyota TransLog data-transmission driving recorder units installed in 500 taxis operating in the Tokyo metropolitan area. This trial service is to start in the spring of 2018.
  • Smart Key Box (SKB): A vehicle owner who wants to lend their car to other people can simply install a Smart Keybox on the dashboard, thereby allowing users to unlock and start the car’s engine safely and securely using their smartphone.
