Lexus unveiled its “Lexus Electrified” vision for an upcoming generation of electrified vehicles. Headlining this was the debut of the Lexus LF-30 Electrified Concept, which made its world premiere at the 46th Tokyo Motor Show 2019.
Since the launch of the RX 400h in 2005, Lexus has led in electrification technologies such as the two-stage reduction gear and the multi-stage hybrid system which leverage technology to offer excellent performance and the direct driving sensation characteristic of Lexus Hybrid vehicles.
The “Lexus Electrified” vision targets a fundamental leap in vehicle performance, handling, control and driver enjoyment—even as mobility within society continues to change with autonomous driving and vehicle electrification.
To achieve a fundamental leap in vehicle performance, handling, control and driver enjoyment, the LF-30 employs numerous state-of-the-art technologies even beyond advanced posture control. In-wheel electric motors for each of the vehicle’s four wheels and low positioning of the battery enable better handling of inertia and high-level driving performance. Autonomous driving technologies and drone support vehicle technologies look ahead to the year 2030 and the widely expanded value that vehicles can offer.
Lexus Advanced Posture Control technology regulates the drive-power output from high-torque electric motors to adjust vehicle posture in tune with human sensibilities. Completely independent control of front and rear drive wheels allows appropriate provision of front-wheel drive, rear-wheel drive, and all-wheel drive, depending on the driving situation. Compact and lightweight drive-power units expand freedom in vehicle packaging and are used to enable the driver to enjoy ideal driving, regardless of the road surface or driving conditions.
Positioning Lexus Advanced Posture Control technology as a core element of the ‘Lexus Electrified’ vision, Lexus intends to widely apply this technology throughout its lineup of electrified vehicles.
The steer-by-wire system eliminates a mechanical connection to allow more flexible turning control depending on driving conditions, and a more precise steering feel aligned with the driver’s intention. It also contributes to a greater sense of openness by allowing the steering controller can be shifted forward and out of the way during autonomous driving.
As a next-generation BEV, LF-30 uses wireless charging technology to simplify daily charging, and AI-based energy management to enable optimal distribution of electric power to both the vehicle and the home, and charging control coordinated with the user’s daily schedule.
Onboard AI distinguishes the voices of vehicle occupants, and uses personalized information stored on the driver’s control key to serve as a partner. It facilitates the adjustment of elements of the interior environment, such as air temperature and audio, and the setting of navigation routes and destinations, while also making proposals for activities after arrival. It also understands the driver’s preferences and helps them control the suspension and powertrain settings in real-time according to the driving scene.
The LF-30 Electrified also carries the ‘Lexus Airporter’ drone-technology support vehicle. Using autonomous control, the Lexus Airporter is capable of such tasks as independently transporting baggage from a household doorstep to the vehicle’s luggage area.
Based on the latest autonomous driving technology concept of ‘Lexus Teammate’, the LF-30 Electrified features advanced driving support functions in the form of a Chauffeur mode and a Guardian mode. Occupants can enjoy both comfort and peace of mind during autonomous driving with advanced posture control technology being employed. Furthermore, a self-parking function and a front-door pickup function in which the LF-30 Electrified autonomously moves from driveway to doorstep provide an especially high level of convenience.
Lexus plans to unveil its first BEV in November 2019—broadening its response to the needs of various regions around the world, including the development of HEVs, PHEVs, BEVs, and FCEVs. Moving forward after that, Lexus plans to expand its electrified vehicle lineup, launching its first PHEV and a new dedicated BEV platform early in the coming decade.
By 2025, Lexus will have available electrified versions of all Lexus vehicle models; the company is aiming for the sales of electrified vehicle models to outpace those of conventional internal combustion engine vehicle models.
