Electric vehicle motor control - using on-board computer with stored selectable travel patterns and motor controlled by signal indicating required position change.

摘要

The method of controlling an electric vehicle motor involves operating the motor in response to a speed/torque signal from a vehicle driver. When the vehicle stops, this state is determined and a position control signal is generated. Another position control signal is generated corresp. to the required (ie another) stop position, chosen by the driver. The motor is then operated accordingly. The vehicle has a computer memory storing a variety of travel patterns, which are used to control the motor torque during the travel sequences. A particular pattern can be chosen by the driver. When the vehicle comes to a halt on a slope, the motor torque is controlled so that the vehicle remains stationary. ADVANTAGE - Vehicle is automatically held stationary at each desired stop position without further driver action.
