ABSTRACT:
A system for recording the total time that a motor vehicle is running, the time that the motor is running while the vehicle is stationary, and the time that the vehicle is running while the vehicle is moving. The system includes three electrically driven timers, one of which is connected in series with the oil pressure switch of the motor so that the timer is energized while the motor is running. The remaining two timers are alternately energized when the output of a speedometer generator is above or below a predetermined value. These timers are also connected in series with the oil pressure switch so that the timers may be not energized unless the engine is running. The record generated by the system can be used to obtain a rebate of road taxes for fuel used while the vehicle is stationary.
