Abstract

The braking system allows the vehicle to be braked at a rate dependent on the vehicle velocity to prevent impact between successive vehicles. The braking is initiated dependent on the relative spacing between 2 successive vehicles. The spring is measured via laser beams projected in front of the vehicle path, with the braking controlled via a computer, supplied with the measured vehicle velocity. USE - For preventing impact between 2 successive vehicles.

Description

Wenn ein Fahrzeug sich einem anderen Fahrzeug nähert, berühren die Laserstranlen das vor ihm fahrende Fahrzeug. Die Laserstrah­ len des nachfolgenden Fahrzeugs induzieren über einen Computer die Bremsung dieses Fahrzeuges. Die Bremsung, die über einen Computer geregelt wird, ist abhängig von der Geschwindigkeit dieses Fahrzeuges.When a vehicle approaches another vehicle, touch the laser stripes the vehicle in front of him. The laser beam len of the following vehicle induce via a computer the braking of this vehicle. The braking that over one Computer controlled depends on the speed of this vehicle.

Das System dieser Bremsung kann bei allen fahrenden Fahrzeugen eingesetzt werden.The system of this braking can be used on all moving vehicles be used.

Die durch Laserstrahlen auf diese Weise induzierte Bremsung ist unabhängig von anderen mechanischen Bremsungen und können parallel eingesetzt werden.The braking induced by laser beams in this way is independent of other mechanical braking and can be parallel be used.

Der Sinn der durch Laserstrahlen induzierten und geschwindig­ keitsabhängigen Bremsung liegt darin, daß viele Unfälle da­ durch vermieden werden können.The sense of induced by laser beams and speedy speed-dependent braking is that there are many accidents can be avoided by.
