A torque control module 10 for a propulsive torque source 20 of a vehicle, typically a hub motor of a wheel, has a controller 11 receiving a signal indicating the acceleration of a vehicle component, typically a wheel. Module 10 compares the component acceleration to a threshold component acceleration corresponding to a threshold vehicle acceleration, for example a plausible acceleration, to determine whether a wheel slip event has occurred. The accelerations may be linear or angular; in an embodiment the threshold may be a linear acceleration of 20 m/s2. The acceleration threshold may be modified dependent on a parameter such as speed, pitch or a selected operating mode. Dependent on the determined and threshold accelerations, a control signal is outputted to reduce a propulsive torque applied to the wheel. The system may be used with an anti-lock braking module.
