ABSTRACT:
A speed governor for a vehicle with an internal combustion engine senses an engine operating condition indicating the vehicle speed. When the vehicle speed indicated by the operating condition exceeds a prescribed speed, the cylinders of the engine are temporarily prevented from firing for short periods until the vehicle speed falls below the prescribed speed. In one form of the invention, a first sensor that senses a first operating condition is used to determine the vehicle speed under normal operating conditions. When the first sensor becomes inappropriate or malfunctions, a second sensor that senses another operating condition is used to determine the vehicle speed.
