Patent FR-2685896-A1 (FR)
Title: Anti-pile-up system
Inventor: RIGOBERT CHARPENTIER HECTOR
IPC: B60T7/16
Filed: 1991-08-14
Abstract: The anti-pile-up device allows several vehicles to brake simultaneously following the signal from the first car facing the danger, thus anticipating the action of the drivers. Each vehicle is equipped with an emitter at the rear and a receiver at the front, coupled with another system. The EMITTER/RECEIVER assembly is of universal frequency. The first vehicle brakes in the face of an obstacle and if it is travelling at more than 90 km/h, the pressure of the brakes triggers the signal of the emitter at the rear of the vehicle and if the car behind is less than 20 metres away and travelling at more than 90 km/h it will in turn brake because its receiver is connected to the speedometer and controls the brake pedal, and so on. A second device will cancel out reflection from vehicles coming in the opposite direction. In order to avoid untimely triggering of the system overall and in order for the device to operate only in the event of absolute necessity, three (3) conditions are necessary:     1) proximity of the vehicles and absence of reflection   2) speed exceeding 90 km/h 3) fierce sharp braking. er
