Early warning of vehicle deceleration
First Claim
1. A communication system for a vehicle located within the vehicle comprising:
- a. a vehicle speed sensor for detecting a speed of the vehicle and that sends a signal to an acceleration monitoring system based on the speed of the vehicle;
b. the acceleration monitoring system for calculating an absolute acceleration of the vehicle based on the signal from the vehicle speed sensor;
c. a braking system engagement detector;
d. a throttle engagement detector; and
e. a control device that receives a signal from the acceleration monitoring system, the braking system engagement detector, and the throttle engagement detector and enters one of a plurality of states, wherein the vehicle emits a signal based upon the state of the control device.

Abstract
A communication system for a vehicle includes a vehicle speed sensor configured to emit a periodic function with a parameter correlated to the speed of the vehicle, an acceleration monitoring system, a braking system engagement detector to detect a braking status of the vehicle, an alerting device capable of signaling other drivers of a deceleration condition of the vehicle, and a control device. The acceleration monitoring system is configured to compute the acceleration of the vehicle from variations in the parameter of the periodic function of the vehicle speed sensor and to output a deceleration status of the vehicle. The control device is coupled to the acceleration monitoring system, the braking system engagement detector, and the alerting device, wherein the acceleration monitoring system sends signals to the control device and the control device operates the alerting device in a manner dependent on the deceleration status of the vehicle.
