An electro-hydraulic power steering system 34 for an electric vehicle comprises a pump 17 providing hydraulic pressure for power steering, and a controller 40 configured to control operation of pump 17 according to an upcoming power steering requirement of the vehicle. The upcoming power steering requirement is preferably predicted according to a vehicle operating condition, such as the location or a route determined by a navigation device. Pump 17 may also be controlled according to a current power steering requirement as determined with reference to a sensor, such as a steering wheel angle sensor, a steering wheel torque sensor, a vehicle speed sensor or a tyre pressure sensor, and the greater of the upcoming and current requirements may be used to control pump 17.
