TAKING the thunder, quite literally from under the competition at the 46th Tokyo Motor Show was Lexus LF-30 electrified concept car. This “Lexus Electrified” vision promises unmatched driver fulfillment with its futuristic exterior, innovative interior that leverages autonomous driving technologies, a newly designed cockpit, while boasting four in-wheel electric motors, steering by wire, and “Lexus Advanced Posture Control.”
“The Lexus Electrified vision targets a fundamental leap in vehicle performance, handling, control and driver enjoyment—even as mobility within our society continues to change with autonomous driving and vehicle electrification,” Toyota said at the presentation of the car last October 24.
Evoking the original fun of driving, Lexus’ electrification technologies were developed to further evolve driving pleasure, and to fundamentally transform the essence of luxury vehicles of the future. The company is drawing on the lessons learned developing the core technologies found in its popular range of gasoline-electric hybrids, including battery management, power control modules, and electric motors.
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.
In particular, the technology of Lexus Electrified enables integrated control of powertrain, steering, suspension, and brakes, realizing the ultimate potential of the motor control technology cultivated in HV. With this technology, we can control the driving force to provide ideal vehicle posture according to each driving situation. Lexus endeavors to continue providing enjoyable and safer driving vehicles.
“For its exterior styling the advanced image expected of a battery electric vehicle (BEV) has been channeled into artistic qualities that result in a futuristic form, and an interior that assertively weaves in autonomous driving and other new technologies aims to manifest Lexus’ distinctive worldview. Performance is rooted in Lexus Electrified components, adding Lexus’ latest technology to our leadership in development of HEV systems. Precise electric motor control enables instantaneous adjustments to posture not possible with conventional vehicles. Furthermore, the LF-30 Electrified employs numerous advanced technologies
with a look ahead to the year 2030- such as a new-concept cockpit based on a human-centered design philosophy and a steer-by-wire system,” the Lexus presentation said.
Taking advantage of a hoodless vehicle shape made possible by being a BEV, Lexus’ signature “spindle” form has been further evolved to span the entire vehicle architecture.
The window glass, which continually stretches from the front to rear, the muscular fenders, and the wing-shaped headlights form the contours of the Lexus iconic spindle. The shape of the body is fashioned with an elegantly flowing front which transitions into a linear and sharp rear. In addition to the wing-shaped headlights, the sharpness of the rear lights and side air intakes combine to achieve both excellent aerodynamics and cooling performance, resulting in styling fused with function.
The interior leverages on autonomous driving technologies, with a newly designed cockpit, focusing on the fundamental human-centered philosophy, the cockpit was designed based on the new Lexus concept of “Tazuna”.
Inspired by how a single rein can be used to achieve mutual understanding between horse and rider, the steering controller-mounted switches and head-up display have been coordinated to a high degree, creating a space that enables the driver to focus on driving while controlling various functions, such as the navigation and audio system and driving-mode selection, without having to shift one’s vision or operate manual switches. The layout of the front passenger seat echoing that of a first-class seat on an airliner, the interior is one in which a sense of openness and a sense of envelopment coexist. All switches and other controls being comfortably within reach and a gesture-control large-screen display for the passenger seat add to the achievement of interior comfort and convenience.
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.
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.
