Abstract

A vehicle monitoring system for turning off an idling engine comprises a vehicle speed sensor configured to detect a lack of motion, or “stationary status” of a vehicle and emit a parameter correlated to the motion status of the vehicle, a transmission status detector configured to detect a transmission status of the vehicle, an alerting device capable of warning other drivers of a stationary status of the vehicle and a control device. The control device is coupled to the vehicle speed sensor, the transmission status detector and the alerting device, wherein the vehicle speed sensor and the transmission status detector send a signal to the control device and the control device operates in a manner dependent on the motion status of the vehicle and the transmission status of the vehicle.

Claims

1-31. -31. (canceled)

32. A system for automatically turning off an idling vehicle engine comprising:

a. a vehicle speed sensor that emits a signal corresponding to a stationary motion status of the vehicle;

b. a transmission status detector for detecting a transmission park status of the vehicle;

c. a control device coupled to the vehicle speed sensor and the transmission status detector; and

d. an idling timer with an expiration time and which is activated after receiving a signal corresponding to the stationary motion status of the vehicle and a transmission park status, wherein the idling timer sends a de-activation signal to the control device upon expiration and the control device turns off the vehicle'"'"'s engine.

33. The system of claim 32 further comprising an alerting device capable of warning other drivers of a stationary status of the vehicle.

34. The system of claim 32, wherein the idling timer is a distinct microprocessor coupled to the vehicle speed sensor and the control device or a microprocessor comprised within the control device.

35. The system of claim 32, wherein the idling timer is programmed to expire after a predetermined period of time.

36. The system of claim 32, wherein the de-activation signal further turns off a lighting system of the vehicle or other accessory equipment.

37. The system of claim 32 further comprising an emergency brake engagement detector to detect engagement of the emergency brake, wherein the emergency brake engagement detector is coupled to the control device to send a signal to the control device, and further wherein the control device operates in a manner dependent on the motion status of the vehicle, the transmission status of the vehicle and the emergency brake engagement status of the vehicle.

38. The system of claim 37 further comprising an external temperature sensor to detect temperature of the external operating environment, wherein the external temperature sensor is coupled to the control device to send a signal to the control device and the control device operates in a manner dependent on the motion status of the vehicle, the transmission status of the vehicle, the emergency brake engagement status of the vehicle and the temperature of the external operating environment.

39. The system of claim 33, wherein upon receiving a signal that the vehicle is stationary, the control device activates the alerting device to warn following drivers that the vehicle is stationary.

40. The system of claim 39, wherein the alerting device is a rear facing amber light.

41. A system for automatically turning off an idling vehicle engine comprising:

a. a vehicle speed sensor that emits a signal corresponding to a stationary motion status of the vehicle;

b. a transmission status detector for detecting a transmission neutral status of the vehicle;

c. an emergency brake engagement detector to detect engagement of the emergency brake;

d. a control device coupled to the vehicle speed sensor, the transmission status detector and the emergency brake engagement detector; and

e. an idling timer with an expiration time and which is activated after receiving a signal corresponding to the stationary motion status of the vehicle, a transmission neutral status and an engagement of the emergency brake, and wherein the idling timer sends a de-activation signal to the control device upon expiration and the control device turns off the vehicle'"'"'s engine.

42. The system of claim 41 further comprising an alerting device capable of warning other drivers of a stationary status of the vehicle.

43. The system of claim 41, wherein the idling timer is a distinct microprocessor coupled to the vehicle speed sensor and the control device or a microprocessor comprised within the control device.

44. The system of claim 41, wherein the idling timer is programmed to expire after a predetermined period of time.

45. The system of claim 41, wherein the de-activation signal further turns off a lighting system of the vehicle or other accessory equipment.

46. The system of claim 41 further comprising an external temperature sensor to detect temperature of the external operating environment, wherein the external temperature sensor is coupled to the control device to send a signal to the control device and the control device operates in a manner dependent on the motion status of the vehicle, the transmission status of the vehicle, the emergency brake engagement status of the vehicle and the temperature of the external operating environment.

47. The system of claim 42, wherein upon receiving a signal that the vehicle is stationary, the control device activates the alerting device to warn following drivers that the vehicle is stationary.
