ABSTRACT:
An all-electric vehicle control system arranges operator interface controls at a console between a pair of seats, either of which can be used by an operator. The console controls include a joystick arranged in communication with an electronic motor control system for driving and regeneratively braking the vehicle wheels. The joystick is also in communication with an electronic servo amplifier and an electric servo actuator that steers the vehicle electromechanically and provides a closed loop feedback circuit for steering control. Electromagnetically actuated brakes are interposed between drive wheels and electric drive motors and are energized automatically whenever the vehicle rolls to a stop, thereby holding the vehicle still. The console also includes a dynamic brake switch that can energize the electromagnetic brakes for decelerating the vehicle in conjunction with regenerative braking. A console-mounted override switch disengages the electromagnetic brakes when the vehicle is stopped so that the vehicle can be moved with external power.
