Abstract: A control system for controlling a powertrain of an electric or hybrid electric vehicle is disclosed. The powertrain comprises a battery and a traction motor and is operable in a regenerative braking mode. The control system is configured to generate a deceleration target for the vehicle in the regenerative braking mode, and to generate a torque command for the traction motor based on the deceleration target. By generating a deceleration target for the vehicle during regenerative braking and using the deceleration target to control the torque of the traction motor, more consistent regenerative braking may be provided, particularly when the vehicle is used to carry different loads.

Abstract: A system for controlling a vehicle speed of a vehicle is described. The system comprises a motor, a vehicle speed sensor, a vehicle speed governor, and a controller. The motor is configured to provide an output torque for driving the vehicle. The vehicle speed sensor provides a vehicle speed signal corresponding to the vehicle speed. The vehicle speed governor has a vehicle speed limit for the vehicle, where the vehicle speed governor adjusts the vehicle speed limit according to a desired direction of travel of the vehicle and a load corresponding to the motor. The desired direction of travel is selectable by an operator of the vehicle. The controller is configured to adjust the output torque of the motor according to the vehicle speed limit and the vehicle speed signal.
