ABSTRACT:
To control both acceleration and deceleration of vehicles having an electric drive with regenerative braking, there is disclosed a control actuator which is biased to a neutral position, and which is controllably moveable between opposed positive and negative control positions relative to the neutral position to produce a control signal ranging from a value corresponding to zero when in the neutral position to a positive or negative value dependent on the amount of movement from the neutral position. The actuator may comprise a rocking foot pedal which is rotationally biased to the neutral position and which is pivotable against the bias both clockwise and anticlockwise from the neutral position to a desired positive or negative power control position. In one system, the signal produced by the actuator is treated as a power control signal and is conditioned and used to control vehicle power (i.e. energy flow from the vehicle battery to the vehicle's electric drive). In another system, the signal produced by the actuator is treated as a speed changing control signal and is conditioned and used to control vehicle speed. Whatever desired speed is reached by movement of the actuator from its neutral position, the speed is sustained if the actuator is then permitted to return to its neutral position.
