Absolute acceleration sensor for use within moving vehicles
First Claim
1. 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;
d. an alerting device capable of warning other drivers of a status of the vehicle, wherein the control device activates the alerting device to warn following drivers of the vehicle'"'"'s status; and
e. an idling timer which is activated upon 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 of a pre-programmed period of time and the control device turns off the vehicle'"'"'s engine.

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.

8. 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; e. an alerting device capable of warning other drivers of a status of the vehicle, wherein the control device activates the alerting device to warn following drivers of the vehicle'"'"'s status; and f. an idling timer which is activated upon 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 of a pre-programmed period of time and the control device turns off the vehicle'"'"'s engine. - View Dependent Claims (9, 10, 11, 12, 16, 17, 18)
