Abstract
The present disclosure relates to a controller for controlling operation of at least first and second traction machines in a vehicle. The controller includes a processor configured to predict an operating temperature of each of said at least first and second traction machines for at least a portion of a current route. The processor determines at least first and second torque requests for said at least first and second traction machines. The at least first and second torque requests are determined in dependence on the predicted operating temperatures of the at least first and second traction machines. The processor generates at least first and second traction motor control signals in dependence on the determined at least first and second torque requests. The present disclosure also relates to method of controlling at least first and second traction machines in a vehicle.
