Concept (top view): In a vehicle, motors M1 through M4 drive respective wheels independently, possibly through respective gear arrangements. Individual-wheel drive (IWD) is an automobile design in which the vehicle has an all-wheel drive powertrain that consists of multiple independent traction motors each supplying torque to a single drive wheel. [1]
This front-wheel drive vehicle has an electric motor that can drive the rear wheels when extra traction is needed. The system is disengaged in all other driving conditions, so it does not directly enhance performance or economy but allows the use of a smaller and more economical engine relative to total performance.
Traction control works by applying individual wheel braking and throttle to maintain traction under acceleration, but unlike ESC, it is not designed to aid in steering. In 1990, Mitsubishi released the Diamante in Japan. Developed to help the driver maintain the intended line through a corner; an onboard computer monitored several vehicle ...
The name is an abbreviation of Universal Wheel Drive System. [2] The Uni Wheel is intended to gain the advantages of individual wheel drive without having to mount the motor directly to, or inside, the wheel. Instead, it subsumes the functions of constant-velocity joints, drive shaft and reduction gearing into a single system within the wheel. [1]
The predecessor of modern electronic traction control systems can be found in high-torque, high-power rear-wheel-drive cars as a limited slip differential.A limited-slip differential is a purely mechanical system that transfers a relatively small amount of power to the non-slipping wheel, while still allowing some wheel spin to occur.
Hacking into your computer and phone was bad enough, but this take the fear for cyber attacks to a whole new level. Hackers can now take over your car's controls, while you are driving.
The U8 features BYD's proprietary "e 4" (易四方) individual wheel drive (IWD) technology, It is the world’s first exclusive intelligent hydraulic body control system for new energy off-road vehicles. with four separate electric motors each propelling a single wheel. This technology allows the traction control system to redistribute torque ...
E-Four (short for Electrical 4WD System), [1] eFour, AWD-i, or AWD-e was developed by Toyota.Front wheels are powered directly by the hybrid powertrain, rear wheels are powered by a dedicated electric motor with its own power control unit, reduction gear and differential.
