ABSTRACT:
A speed control for a wheeled vehicle which is propelled by a motive device that has a speed proportional to the vehicle speed, and a power output control to control the speed of the motive device. A first signal generator generates a signal proportional to a desired vehicle speed. A second signal generator generates a signal proportional to the actual vehicle speed. A comparator compares the signals to detect any difference, and controls an actuator to adjust the power output control to tend to eliminate the difference. The actual speed will thereby tend to approach the desired speed. The first signal generator can, if desired, be operated by the occupant of the vehicle as part of his propulsive effort, for example by driving a bicycle chain drive. The speed control also can have provisions to continue operations at a pre-set rate even when the first signal generator may be inactive, and to make appropriate power control settings at start-up and at the beginning of acceleration conditions.
