Electronic anti-collison device carried on board a vehicle
First Claim
1. An electronic device carried on board vehicles and for transmitting information from a vehicle to a vehicle following it over a given route and for receiving information coming from a vehicle preceding it over this same route wherein there is provided:
- for transmitting information;
a chronometric scanner adapted to detect a possible deceleration of the vehicle by comparing, at specific time intervals values of speed such that said values of speed are communicated to said scanner by a sensor and, in the event that the deceleration detected exceeds a certain threshold, to send a corresponding signal to a radio transmitter device;
said radio transmitter device adapted to transmit a deceleration signal via a directional antenna placed at the rear of the vehicle, andfor receiving information;
a radio receiver device adapted to receive, via a directional antenna placed at the front of the vehicle, a deceleration signal emitted by a vehicle preceding it and to transmit said deceleration signal to an alarm circuit,said alarm circuit adapted to emit, in the event of receiving a deceleration signal, a visual and/or audible alarm in the passenger compartment of the vehicle,and the said transmitter and said receiver are connected to a frequency selector which is manually or automatically controlled to select a frequency based upon the direction of the traffic and of the route taken by the vehicle.

Abstract
An electronic device for being carried on a vehicle for transmitting information to a vehicle following it over a given route. The electronic device is also intended to receive information coming from a vehicle preceding it over the same route. The device includes a transmitter for transmitting information and a chronometric scanner adapted to detect deceleration of the vehicle by comparing speed values communicated to it by sensor. In the event that deceleration values exceed a certain threshold, a signal is sent to a radio transmitter device adapted to transmit a deceleration signal via an antenna on the rear of the vehicle. The electronic device also includes a radio receiver for receiving information from an antenna at the front of the vehicle regarding deceleration of vehicle in front of the vehicle. An alarm device emits a visual and/or audible alarm in the event of sudden deceleration of a vehicle preceding it.
