HSR-VI, the sixth generation of experimental concept cars Mitsubishi Motors has developed since 1987, is devised to work with hypothetical traffic management systems of the future.
It incorporates conventional and automated driving modes with technologies to maximize safety, performance, environmental protection and information exchange.
HSR-VI’s on-board computer takes information from traffic control devices, laser radar and stereo-imaging sensor, to drive itself. HSR-VI is programmed to automatically take the most efficient route to avoid traffic jams, apply the brakes when needed or move to a clear traffic lane when an obstacle is detected.
In the automated driving mode, HSR-VI drops to its lowest position, giving the car a height of just more than four feet to improve aerodynamics and efficiency.
In this position, HSR-VI’s seats recline and the driving controls retract into the instrument panel, allowing its occupants additional comfort and room. Passengers also can use the HSR-VI’s communication system to make phone calls, catch up with the news, send e-mail and browse the Internet.
If the driver chooses, HSR-VI can be driven conventionally. The interior rises by approximately one foot to give the driver a panoramic view of the road similar to that of a sport-utility vehicle.
The accident avoidance technology that allows HSR-VI to operate in its automated mode remains functional. For example, if the driver enters a one-way street, exceeds the speed limit or fails to slow down at a stop light, HSR-VI will display a warning, sound an alarm and apply the brakes.
In lieu of conventional pedals, the HSR-VI is operated by the steering wheel. Shaped like an airplane flight stick, the steering wheel incorporates the accelerator and brake levers.
To keep distractions to the driver at a minimum, the instrument panel displays only information necessary at any given time, and the climate controls and audio system are designed to be used with minimal interaction by the driver.
If these systems determine that the driver is unfamiliar with the controls, instructions are displayed.
HSR-VI is constructed with a rigid, extruded aluminum space frame covered with a polycarbonate material that absorbs impact energy in an accident. The material is also treated to cut ultraviolet rays to keep the cabin cooler.
The windshield and side windows are coated with a silicone-based resin that repels water in rainy conditions; at speeds low enough that water collects on the windshield, jet wipers shoot blasts of air to blow it away.
Even the driver does not escape scrutiny. Cameras with infrared lights monitor the driver’s blinking and eye movements and will sound an alarm if the driver falls asleep or loses attention.
HSR-VI has a 2.4-liter, dual overhead cam 4-cylinder engine that employs Mitsubishi’s direct-injection technology, which provides more power and fuel efficiency than a conventional engine of the same size, while reducing exhaust emissions.
Using All-Wheel Control, HSR-VI incorporates several systems to enhance handling and traction: Active Yaw Control balances traction among all four wheels, optimizing cornering by transferring torque to the left or right front and rear wheels. It improves steering accuracy without applying the brakes or reducing engine output.
In addition, HSR-VI controls cornering and braking by transferring power to the left or right as necessary. Four-wheel steering allows the car to corner exactly as the driver wishes.
Also, HSR-VI has an electronically controlled suspension, improving cornering and ride comfort by automatically adjusting suspension damping and vehicle height.
