Abstract

An apparatus is provided for diagnosing the state of health of a vehicle and for providing the operator of the vehicle with a substantially real-time indication of the efficiency of the vehicle in performing an assigned task with respect to a predetermined goal. A processor on-board the vehicle monitors sensors that provide information regarding the state of health of the vehicle and the amount of work the vehicle has done. In response to anomalies in the data from the sensors, the processor records information that describes events leading up to the occurrence of the anomaly for later analysis that can be used to diagnose the cause of the anomaly. The sensors are also used to prompt the operator of the vehicle to operate the vehicle at optimum efficiency.

Claims

1. A method for recording operation of a vehicle, the method comprising:

monitoring production-related parameters of the vehicle, including engine RPM, ground speed of the vehicle and distance traveled;

monitoring one or more vital sign parameters of the vehicle;

capturing values of the production-related parameters into a first memory;

detecting a critical event in response to one or more values comprising values of either or both vital sign parameters or production-related parameters of the vehicle; and

recording to a second memory at least values of the engine RPM and the ground speed of the vehicle corresponding to a period of time immediately preceding detection of the critical event.

2. The method of claim 1 including recording the critical event to the second memory.

3. The method of claim 1 wherein the monitoring of production-related parameters includes monitoring braking of the vehicle.

4. The method of claim 1 wherein the recording to a second memory includes recording at least the value of ground speed after the detection of the critical event.

5. The method of claim 1 wherein one of the vital signs is sudden changes in velocity indicative of a collision.

6. The method of claim 5 wherein the critical event is a collision of the vehicle.

7. The method of claim 1 wherein the production related parameters include a load on the engine.

8. The method of claim 7 wherein the load on the engine includes engine fuel consumption.

9. The method of claim 1 wherein the production-related parameters include a status of a seat belt.

10. The method of claim 1 wherein the production-related parameters include actions of a steering wheel.

11. The method of claim 1 including automatically sending a wireless distress signal from the vehicle in response to detecting the critical event.

12. The method of claim 3 wherein the braking of the vehicle includes an on/off status of a braking system of the vehicle.

13. The method of claim 3 wherein the braking of the vehicle includes a degree of braking.

14. An apparatus for recording operation of a vehicle, the apparatus comprising:

sensors for monitoring production-related parameters of the vehicle, including engine RPM, ground speed of the vehicle and distance traveled;

a first memory for capturing information from the sensors for monitoring production-related parameters;

a second memory adapted to receive the information from the first memory;

sensors for monitoring vital signs of the vehicle; and

a processor in communication with the production-related and vital sign sensors and the first and second memories for detecting a critical event in response to anomalies in one or more values comprising values of either or both vital sign parameters or production-related parameters, the processor being adapted to record into the second memory the information captured by the first memory corresponding to a period of time immediately preceding detection of the critical event.

15. The apparatus of claim 14 wherein the processor records the critical event into the second memory with the captured information recorded into the second memory.

16. The apparatus of claim 14 wherein the sensors for monitoring production-related parameters of the vehicle includes one or more sensors for sensing braking of the vehicle.

17. The apparatus of claim 14 wherein the information recorded into the second memory includes information from one of the production-related parameters both immediately preceding the detection of the critical event and after the critical event.

18. The apparatus of claim 14 including a transmitter for automatically transmitting a distress signal in response to detection of the critical event.

19. The apparatus of claim 14 wherein the sensors for monitoring production-related parameters includes a sensor for monitoring a load on the engine.

20. The apparatus of claim 14 wherein one of the vital signs sensors is an accelerometer.

21. The apparatus of claim 14 wherein the information indicates a change in the speed of the vehicle both before and after detection of the critical event.

22. The apparatus of claim 16 wherein the sensors for monitoring production-related parameters includes a sensor for detecting an on/off status of the braking system.

23. The apparatus of claim 16 wherein the information includes a degree of braking leading up to the detection of the critical event.

24. The apparatus of claim 14 wherein the information includes one or more positions of a throttle leading up to the detection of the critical event.

25. The apparatus of claim 14 wherein the sensors for monitoring production-related parameters of the vehicle include a sensor for determining a state of a seat belt in the vehicle.

26. The apparatus of claim 14 wherein the second memory is a permanent memory.
