Patent ID: 8428839

Claim:
A method of forming a communication system for a vehicle comprising: a. providing a deceleration warning circuit, the deceleration detection warning circuit comprising: i. a deceleration detector, wherein the deceleration detector detects any deceleration of the vehicle; ii. a gyroscope, wherein the gyroscope detects an inclination of the vehicle relative to a gravitational acceleration; iii. a logic circuit configured to determine an absolute deceleration from the deceleration of the vehicle and the inclination of the vehicle; iv. a braking system engagement detector, wherein the braking system engagement detector any engagement of a braking system of the vehicle; v. a control device coupled to the deceleration detector and the braking system engagement detector, wherein the logic circuit and the braking system engagement detector send signals to the control device, and wherein the control device activates brake lamps of the vehicle if the absolute deceleration of the vehicle is positive; and b. coupling the deceleration warning circuit to a brake lamp system of the vehicle.
