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.

Claims

1. A fuel tax rebate recorder for motor vehicles, comprising:

a first signal generator producing a motor running indication when the motor of said vehicle is running;

a second signal generator producing a vehicle moving indication when said vehicle is moving faster than a predetermined velocity, said second signal generator including a speedometer generator coupled to the drive train of said vehicle, said speedometer generator producing an electrical signal having a characteristic that is proportional to the speed of said vehicle, said second signal generator further including a sensing device receiving the signal produced by said speedometer generator, said sensing device being triggered responsive to said speedometer generator indicating a speed exceeding a predetermined value, said sensing device producing said vehicle moving indication as said sensing device is triggered; and

timer means for separately recording at least two out of three time parameters, said time parameters being the period of time that said first signal generator is producing said motor running indication, the period of time that said second signal generator is producing said vehicle moving indication above said predetermined velocity, and the period of time that said first signal generator is producing said motor running indication but said vehicle is moving below said predetermined velocity, said vehicle moving time indications above and below said predetermined velocity being incremented alternatively.

2. The fuel tax rebate recorder of claim 1 wherein said timer means records all three of said time parameters.

5. The fuel tax rebate recorder of claim 1 wherein said sensing device is a voltage-sensing relay receiving the signal produced by said speedometer generator, said voltage-sensing relay being energized to move a relay contact from one position to another responsive to the signal produced by said speedometer generator indicating a speed exceeding a predetermined value, said relay contact being connected in an electrical circuit so that the voltage across said contact changes to produce said vehicle moving indication as said relay contact changes position.

6. The fuel tax rebate recorder of claim 5 wherein said timer means includes an electrically driven timer connected in series with said relay contact, a source of DC power in ground so that a circuit through said timer is completed when said relay contact closes.

7. The fuel tax rebate recorder of claim 6, further including an oil pressure having an electrical contact in series with said relay contact, said electrical contact changing from an open to a closed position as the oil pressure in said motor rises to and above normal operating pressure, whereby said electrically driven timer is precluded from incrementing unless said engine is running.

3. A fuel tax rebate recorder for motor vehicles, comprising:

an oil pressure switch having an electrical contact changing from one position to another as the oil pressure in said motor rises to and above normal operating pressure, said contact being connected in an electrical circuit providing a voltage across said contact to produce a motor running indication as said contact changes position;

a second signal generator producing a vehicle moving indication when said vehicle is moving faster than a predetermined velocity; and

timer means for separately recording at least two out of three time parameters, said time parameters being the period of time that said first signal generator is producing said motor running indication, the period of time that said second signal generator is producing said vehicle moving indication above said predetermined velocity, and the period of time that said first signal generator is producing said motor running indication but said vehicle is moving below said predetermined velocity, said vehicle moving time indications above and below said predetermined velocity being incremented alternatively.

4. The fuel tax rebate recorder of claim 3 wherein said timer means include an electrically driven timer connected in series with said oil pressure switch, a source of DC power and ground so that a circuit through said timer is completed when the contact of said oil pressure switch closes.

8. A fuel tax rebate recorder for motor vehicles, comprising:

first, second and third electrically driven timers, each providing a visual readout that increments when an electric current flows through said timer;

a double-pole relay having a normally open contact and a normally closed contact both of which are actuated by current flowing through a relay coil, said normally open contact being connected in series with said first timer and said normally closed contact being connected in series with said second timer;

a speedometer generator coupled to the drive train of said vehicle, said speedometer generator producing an electrical speed signal having a magnitude that is proportional to the speed of said vehicle;

an oil pressure switch having a contact that closes to connect a pair of terminals to each other when the oil pressure in the motor of said vehicle has a magnitude that is present during normal operating conditions, one terminal of said oil pressure switch being connected to said third timer and to the contacts of said relay;

a DC power source connected in series with said timers and said oil pressure switch; and

a speed switch connected to said speedometer generator, said speed switch having a contact that closes when the magnitude of said speed signal is greater than a predetermined value, said contact being connected in series with a voltage source and the relay coil of said relay, whereby said third timer increments whenever said motor is running, said first timer increments whenever said motor is running and said vehicle is moving at a speed causing said speed signal to exceed said predetermined value, and said second timer increments whenever said motor is running and at a speed causing said speed signal to be less than said predetermined value.
