The theme of this year’s Tokyo Motor Show was “Open Future”, and the show has been reinvented to provide visitors with a vision of a future mobility society; to this end, the show’s scope has been expanded to encompass sub-themes like “The Excitement of Cars”, “Future Homes,” and “Future Towns.”
Seven DVN Tokyo Takeaways:
1. The show was almost entirely Japanese. Daimler and
Renault were there, but that’s about it for non-Japanese automakers, and those
two European companies didn’t launch any world-firsts at the Tokyo show; it
really is a regionally-focused event. As such…
2. The cars shown catered for the needs and wants of a densely-populated country with few onshore energy resources. So there were lots of EVs, small and really small cars, and retro-styled car concepts.
3. The auto usage development path is forking; splitting in two: city mobility with small cars, and driving pleasure with bigger ones. Lighting to meet new use cases have to be studied and understood.
4. Japanes makers presented interesting cars and technologies,with some very imaginative innovations.
5. Clean mobility is presented and seen as a high priority. Cleaner engines, electrics, and hybrids dominated the show; most of the presentations and communications were focused on EVs. Automakers are facing tightening emissions restrictions in many markets—in Europe, for example, makers will have to pay huge penalties if they violate the 95 g/km CO2 threshold in 2020—and buyers increasingly prioritise a reduced climate footprint.
Communication by lighting is gaining traction. Ichikoh and Koito put forth strong presentations with a
variety of concepts.
7. Interior lighting is going from strength to strength. There were a lot of concept cars with a great deal of interior lighting innovation on display. The Toyota-Lexus cars were one notable example.
a loo at some of the particularly interesting cars we saw at Tokyo this year:
The WaiWai is a “comfortably spacious, perfectly-sized mini-van, a 3-row/6-seater with a spacious interior the maker says encourages users to go out and have fun. Additional openness is provided by the sunroof.
Isuzu are striving to appeal to diverse customers by offering a wide range of variations of this newly modernised truck. They’re working to leverage their core business operations to increase sales and take a lead in the LCV market.
Lexus LF-30 Concept
The LF-30 embodies the “Lexus Electrified” vision put
forth by the company. It was presented as a look ahead to the cars of 2030 with
features such as a new-concept cockpit based on a human-centred design
philosophy and a steer-by-wire system. The exterior design, too, is said to
suggest what a Lexus EV of the 2030s might look like.
The window glass, which contiguously runs from the front to rear, and the wing-shaped headlamps form the contours of the car.
It’s a small electric SUV concept.
The front end adopts
MMC’s new Dynamic Shield front design concept, which has a satin metal look to the
central “grille”, and copper accents to subtly hint at the car’s
T-shaped headlamps are embedded in the front end to emphasize a distinguishing outward appearance. The rear styling evinces a big, bold hexagon carved from a metal ingot. It’s got T-shaped tail lamps that echo the front light design.
Nissan Ariya Concept
Nissan showed their Ariya Concept, an twin-motor electric crossover with powerful acceleration, comprehensive driver assistance technology, and a big shift in the direction of Nissan design.
The Ariya presents an electrified V-motion signature “shield” up front, visually striking rear light blades, short overhangs, and an interior that feels more like a lounge than a conventional vehicle.
Subaru Levorg Prototype
Subaru showed their new second-generation Levorg for the first time at Tokyo. Subaru say they envision “a future that everyone can enjoy driving at the full, at their will”, and the Levorg prototype is definitely firmly in an era where autonomous driving technology is widely spreading.
Suzuki Waku SPO
Here’s a plug-in hybrid small coupé with old-style wing mirrors (for many years, Japanese regulations required this type of sideview mirror). It is a personal compact PHEV. The lighting is full-LED, and there’s a screenlike “grille” that might resemble a robot’s face.
The large radiator grille embellished with metallic accents flows seamlessly into the headlamps, which project in vertical and horizontal directions, providing the van with expressive, sophisticated eyes.
Woodgrain decorations flow from the back of the front seats toward the side trim. The LED side colour illumination is gently lit.
The Granace comes standard with the latest version of Toyota Safety Sense, featuring improved sensing functions that make use of the pre-collision safety system that detects pedestrians during the day and at night, as well as cyclists during the day.
Toyota Tokyo (2020 Version) e-Palette
The e-Palette is Toyota’s first vehicle developed specifically for autonomous MaaS applications. It reflects Toyota’s ongoing transition to a mobility company and combines electrification, connected networks, and advanced driving technologies to support new shared mobility businesses and business models.
The e-Palette is equipped with a specially-designed automated driving system that includes control hardware, software, and advanced sensors such as cameras and lidar. Combined with high-accuracy 3D mapping and an operation management system, e-Palette will achieve low-speed automated driving at SAE level 4. Both front and rear lamps mimic eye contact to inform pedestrians of vehicle actions—we’re not sure these particular configurations are necessarily intuitive, understandable, or optimal, but they do demonstrate the concept.
Toyota LQ Concept
Toyota say their LQ leverages advanced technology to build an emotional bond between car and driver.
It uses the roof and floor mat areas as an intuitive communications platform to share information between the vehicle and passengers. Embedded lighting displays different colours to indicate automated or manual driving mode, and lights up different foot wells to indicate which passenger the car is addressing.
It can also communicate information such as road surface conditions to people inside and outside of the vehicle using the DMD in the headlamps The system can activate one million tiny embedded mirrors to project complex figures on the road ahead.
The dashboard displays use OLEDs. The advanced instrument panel design wraps around the driver.
Toyota Mirai Concept
The totally redesigned Mirai concept portends a major step forward for FCEVs and the potential of a hydrogen-based energy stream. It’s got significantly greater range and improved driving performance compared to the first Mirai, and an elegant, sporty design that offers increased passenger room.
New headlamps feature LED technology, including turn unitary turn signal/DRL units.
By installing sensors (lidar, cameras,
millimeter-wave radars) into headlamps and rear combination lamps in the four
corners of the vehicle, next-generation lamps detect objects 360° around the
vehicle at an early stage.
KOITO also provides pedestrian-to-vehicle communications by promptly informing drivers or pedestrians with necessary information by using “Lights.”
Signal Lamps for AV
AV marker to indicate that the vehicle is running in autonomous mode.
AV signal to indicate signs to inform that the vehicle to move or giving a road to pedestrians.
Road projecting lamps help pedestrian to vehicle communication with facial recognition linked inforamtion. For example,in the ride-fhailing service,the lamp recognises the road and displays reservation information on the vehicle body and on the road.
BladeScan ADB Headlamp System
By turning on/off 12 LEDs and controlling the rotation of the blade mirrors.
BladeScan ADB ensures high-resolution light distribution equivalent to the use of hundreds of LEDs while minimizes shading area. BladeScan ADB helps driver to early detect pedestrians, this contrbutes to reduce traffic accidents.
Light distribution performance : As BladeScan ADB enable to light vicinty of vehicles ahead.,they help driver detect pedestrians at an early stage.
Koito’s road projecting headlamp support vehicles’ driving by projecting information on the road,which is linked to the vehicle’s navigation system. It is also expected to promotes pedestorians’ awareness.
By using DMD with more than one million micromirrors,road projecting headlamps control light precisely,and projects figures or letters on the road.
Ichikoh exhibited a full-scale mock-up of “Communication Lighting”, a system that indicates the intention of the car by using lights instead of the driver’s hands and face. It will be the lighting as HMI (Human Machine Interface), employed to exchange information between human and vehicles in the automated driving society. Using about 400 LEDs, Communication Lighting indicates the movement (intention) of the car to surrounding drivers and pedestrians by using light sign during automated driving instead of the driver’s eye contact and gestures.
Ichikoh also displayed about 10 types of scenarios such as “Thank you” for oncoming vehicles and “You can go across” for pedestrians and verify whether the intention of the vehicle is conveyed to visitors.
The company’s slogan, “Powering Progress
Together”, is emblematic of a focus on helping their customers confidently
navigate and succeed in an unprecedentedly changing industry.
Marelli is introducing products and services in the areas for Autonomous Driving, Connected Systems, Electrification, and Green Technology.
Marelli presented the latest iteration of their Smart Corner™, wherein sensors for autonomous driving are integrated in the headlamp: light-detecting devices using infrared cameras, lidars, and short and long-distance radars) into headlight and rear light units, which are used to create maps of the surrounding environment to support autonomous driving.
