An electric vehicle control system controls motor response based upon monitored vehicle characteristics to provide consistent vehicle performance under a variety of conditions for a given accelerator manipulation. In one example, motor temperature is monitored. As the temperature increases, the gain of a power signal provided to the motor is increased to make up for the motor's hindered performance under higher temperature conditions. Other vehicle characteristics that are taken into account include a charge level in a fuel cell or current vehicle speed and engine load.

1. A method of controlling motor response in an electrically powered vehicle having a motor and a manually operable accelerator, comprising the steps of:monitoring a temperature of the motor; determining a maximum available power output based upon the current motor temperature; and increasing the motor response to manipulation of the accelerator as the determined heat increases.
