Abstract

An electric motor controller adapted to provide anti-lock braking of an electric traction motor for an electric vehicle is disclosed herein. The electric motor controller comprises a torque demand input for receiving a torque demand input signal based on a request from an operator of the electric vehicle and a torque demand adjuster adapted to adjust the torque demand input signal and to provide an adjusted torque demand signal. The torque demand adjuster is configured to adjust the torque demand signal such that the motor is controlled to reduce the difference between a motor speed and an estimated speed of the electric vehicle.
