Abstract
A torque drive and control system for a vehicle having a plurality of driven wheels is disclosed. The system comprises a plurality of in-wheel electric motors for mounting within each respective driven wheel of the type having a plurality of coils forming a stator radially surrounded by a plurality of magnets forming a rotor; a control circuit within each electric motor for controlling a switching of voltage applied to coils of that motor to thereby control 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; means for transmitting the speed of each motor to each other motor in the vehicle; wherein each control circuit 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.
