An apparatus for controlling vehicle movement comprises processing means configured to receive first signals from a receiving means arranged to receive transmitted signals from a remote control device indicating a requested motion of the vehicle. From the first signals or an additional signal received from a sensing means, one or more distance values indicative of a distance from a point on the vehicle to an object is determined, and a maximum speed value for the vehicle is determine in dependence on the one or more distance values. The processing means provides an output signal for controlling speed of the vehicle based on the requested motion. The output signal is arranged to control the speed of the vehicle to be less than or equal to the maximum speed value.
