ABSTRACT:
A hill-holding arrangement for an electrically driven vehicle includes a vehicle with a "gas pedal" which generates a torque command signal T.sub.CMD. A switch (314) couples T.sub.CMD to a motor controller (316, 14) which drives the motor (40) and therefore the vehicle. When the "gas pedal" calls for zero torque, and the vehicle speed is zero, the switch responds to logic (FIG. 5), and substitutes a position-holding torque command signal T.sub..theta. for the operator-controlled torque command signal T.sub.CMD. Position controlling torque command T.sub..theta. is generated by a controller (312) which receives a position signal representative of the angular position .theta. of the rotor. The position-holding torque control loop then produces such torque as may be required to prevent the rotor of the motor from moving from its commanded position.
