ELECTRIC VEHICLE WITH ADAPTIVE CRUISE CONTROL SYSTEM

摘要

A novel system for adaptively controlling an electric vehicle to maintain desired speed under variable driving conditions. The system includes a control circuit for producing a control signal to control an electric motor of the vehicle. The control signal is formed based on a control current required to achieve the desired speed. The control strategy selection circuit is configured in the system to determine a motor control scheme that provides an appropriate waveform profile of the control current. Sinusoidal waveforms are used for high efficiency and rectangular waveforms ar used for high torque.
