Abstract
A universal command signal producing apparatus adapted for use in an electrically operated vehicle. The apparatus includes a rotatable electrical element for use in controlling a drive function of the vehicle, such as a speed control function or a braking function. The apparatus is arranged to act as a transducer between a foot pedal, adapted to be actuated by the user of the vehicle, and the propulsion control to selectively control the electric drive motor of the vehicle or the braking system thereof. The transducer apparatus may include a sprocket associated with the rotatable electrical control device and driven by a chain forming a part of the transducer. The chain may be mounted on a suitable carrier which is adapted to be moved by movement of the foot pedal. The transducer may include a rotatable transverse shaft actuated by the foot pedal and arranged so as to have the foot pedal selectively installed at either end of the shaft so that the vehicle may selectively be operated as either a left- or righthand drive vehicle. When used as a brake control, the transducer may be operated hydraulically whereby the system provides concurrent hydraulic and regenerative braking of the vehicle.
