Abstract
A motor driven vehicle has a safety control preventing operation of the motor if the operator is not in the drivers seat to close a seat switch for a predetermined period of time. The motor includes an electric circuit which when complete enables motor operation and which prevents motor operation when the circuit is open. A microprocessor opens the circuit when the seat switch is open and is programmed to provide a predetermined time delay before opening the circuit to stop motor operation. The computer decrements the time delay whenever the seat switch is open. The computer includes means for testing to determine whether the time delay has been reduced to 0 at periodic intervals shorter than the predetermined time delay. The decremented time delay is restored to full value if the seat switch is closed during such testing before said time delay has been decremented to 0.
