Mitsubishi Electric, which is a separate company to Mitsubishi Motors Corporation, is at the 2013 Tokyo Motor Show presenting its latest electric drivetrain products fitted in EMIRAI 2 "xEV" electric vehicle.

The small 2-seater xEV gets 125 kW of peak power and AWD with three electric motors - one per wheel... No, that can't be right... actually, the front motor is bigger and drives two wheels.

This mean that Mitsubishi Electric has developed two different types of motors and is now looking to attract some automakers.

Per Mitsubishi Electric:

EMIRAI 2 xEV: Powertrain Concept Car

The EMIRAI 2 xEV is a four-wheel-drive EV with a maximum output of 125kW. It is equipped with three motors, one to drive the front wheels and two to drive the left and right rear wheels independently. Built with Mitsubishi Electric's proprietary original motor control technology, the vehicle promises a high-quality EV driving experience on any road condition.

High-precision Traction Control Traction control is important for safe driving on snowy roads, where tires can easily lose traction. The EMIRAI 2 xEV identifies tire slippage by controlling motor torque every 1msec (1/1000th of a second). If slippage is detected, motor output is precisely lowered to match the degree of slippage. The driver is informed when traction control is activated via an icon on the Intelligent Information Panel.

Smooth-G Control for enhanced acceleration and deceleration The EMIRAI 2 xEV's Smooth-G Control enhances acceleration both from a full stop and when under way to provide smooth acceleration without unexpected jolts. If vibration caused by increased motor torque is detected, torque is controlled to eliminate unpleasant sensations. Smooth-G Control also enhances the pleasurable sensation of acceleration by smoothly controlling torque startup with respect to the car's structural characteristics.

Low-speed Level Control

The EMIRAI 2 xEV's Low-speed Level Control enables the driver to maintain constant low speed on uneven roads, which is not possible with internal-combustion vehicles. For example, when driving over speed bumps or on graded roads, motor output torque is instantly controlled in response to differences in road level to eliminate unnecessary acceleration or braking, making it easy to maintain the car's desired position.



The second prototype has nothing to do with motors. xDAS is a "Driving Assistance Concept Car" recalling a computer on wheels. Mitsubishi Electric demonstrates some new technologies in xDAS, which can be implemented in any vehicles regardless of the drive:

"The EMIRAI 2 xDAS EV concept car combines an interior design, information systems and advanced operation harmonized to the driver under the concept of a highly driver-oriented car. It incorporates Mitsubishi Electric's advanced technologies for video display, image sensor processing and human-machine interface to assist the driver in achieving exceptionally safe and comfortable driving."

Per Mitsubishi Electric:

Driver-oriented interior The EMIRAI 2 xDAS is equipped with the Intelligent Information Panel, a next-generation display that seamlessly changes its appearance and content in response to driver preferences and driving conditions, ensuring that the driver always has the desired and required information in an easy-to-understand fashion.

(1) Situational display
Appearance and content are available in three variations on the windshield head-up display (HUD) in response to driving conditions. When the car is parked, information includes content such as navigation, music and social networking services (SNS). When the car is running, only information needed for driving is provided to ensure safety.
(2) User-selected interface
Contents on the panel display can be changed in response to user preferences. Cloud content synchronization and selectable panel layouts enable the driver to create a highly personalized interior.

Driver-oriented information The Intelligent Information Panel presents information about potential driving dangers and other essential information that the driver requires.

(1) Integrated Image Sensing
Impending dangers are detected by cameras and displayed on the windshield HUD. A visual sensor analyzes the driver's awareness for selective notification of high risks.
(2) "What's that?" Search
This voice-activated feature provides the driver with pinpoint information using visual sensors and high-precision vehicle positioning. Identification is implemented both via the windshield HUD and audibly. Drivers can keep their eyes on the road ahead while obtaining information easily and safely, simply by voicing "What's that?" as if speaking to a passenger.

Driver-oriented operation The EMIRAI 2 xDAS's Natural User Interface anticipates driver actions for simple, safe and intuitive operations in response to audio and handwritten prompts.

(1) Smart menu
Based both on operational history and driving conditions (time of day, road conditions, etc.), the three most necessary operations are displayed on the Intelligent Information Panel. Screens for each of these three operations can be accessed simply by pressing the corresponding button on the steering wheel, contributing to simpler and safer operation.
(2) Smart Steering Wheel
The steering wheel is equipped with a device that incorporates a touchscreen featuring ergonomic surfaces. Intuitive functionality is achieved via either cursor operation or handwritten entries."
