Abstract
Official abstract text for this publication.
A torque control system for a vehicle having a plurality of wheels, wherein at least two of the wheels are arranged to be driven by separate electric motors, the system comprising a master controller arranged to monitor the torque generated by at least one of the electric motors and upon a determination that the torque produced by the at least one electric motor is reduced as a result of a predetermined condition the master controller is arranged to adjust the torque generated in the at least one electric motor and/or another electric motor so that the torque generated by the at least one electric motor and the another electric motor are substantially the same.
First claim
Opening claim text (preview).
The invention claimed is: 1. A torque control system for a vehicle having a plurality of wheels, wherein at least two of the wheels are arranged to be driven by separate electric motors, wherein each of the electric motors includes a plurality of motor drive controllers that are arranged to drive separate motor coils, the system comprising a controller arranged to monitor the torque generated by at least one of the electric motors and another electric motor and upon a determination that the torque produced by the at least one electric motor is reduced as a result of a failure of one of the motor drive controllers the controller is arranged to adjust the torque generated in the at least one electric motor by arranging at least one of the other motor drive controllers to increase torque generated by their respective motor coils so that the torque generated by the at least one electric motor and the another electric motor have a predetermined relationship. 2. A torque control system according to claim 1 , wherein the predetermined torque relationship is the torque generated by the at least one electric motor and the another electric motor is substantially the same. 3. A torque control system according to claim 1 , wherein the electric motors are in-wheel electric motors. 4. A method of controlling torque for a vehicle having a plurality of wheels, wherein at least two of the wheels are arranged to be driven by separate electric motors, wherein each of the electric motors includes a plurality of motor drive controllers that are arranged to drive separate motor coils, the method comprising monitoring the torque generated by at least one of the electric motors and another electric motor and upon a determination that the torque produced by the at least one electric motor is reduced as a result of a failure of one of the motor drive controllers adjusting the torque generated in the at least one electric motor by arranging at least one of the other motor drive controllers to increase torque generated by their respective motor coils so that the torque generated by the at least one electric motor and the another electric motor have a predetermined relationship. 5. A method of controlling torque according to claim 4 , wherein the predetermined torque relationship is the torque generated by the at least one electric motor and the another electric motor is substantially the same.
