Abstract

A torque drive and control system for a vehicle having a plurality of driven wheels is disclosed. The vehicle comprises a plurality of in-wheel electric motors for mounting within each respective driven wheel of the type having a plurality of coils (54, 56, 58, 74A, 74B, 740 see figs 3 and 4) forming a stator 252 radially surrounded by a plurality of magnets forming a rotor 240. A control circuit 80 within each electric motor for controlling a switching of voltage applied to coils (54, 56, 58, 74A, 74B, 74C) of that motor is provided. This controls the accelerating or braking torque provided by the motor. Means associated with each respective electric motor for detecting the speed of rotation of the motor and means for transmitting the speed of each motor to each other motor in the vehicle are provided. Each control circuit 80 is configured to adjust the torque provided by each respective motor in response to the detected speed of rotation of the motor and the speed of rotation of at least one other motor. A vehicle (see fig 9) may comprise a separate electric motor in each wheel, wherein torque is controlled to improve vehicle handling.
