DEVICE FOR PROTECTION AGAINST COLLISIONS FOR PARKED AUTOMOTIVE VEHICLES

The present invention consists in a device located in vehicles equipped with ultrasonic devices for measuring distances, which is intended to protect the same when it is parked so as to prevent other vehicles performing parking or positioning maneuvers from impacting the same. Original ultrasound equipment is not designed for providing protection once the driver removes the ignition key, so that the ultrasonic measurement units are turned off and completely ineffective when the automobile is parked or turned off; the device against collisions for parked vehicles is installed in the electric interconnection network of the vehicle in such a manner that the vehicle will maintain all original functions and the device may use the ultrasonic units, which may be activated when the vehicle is parked, also taking control of the lights and horn for warning drivers when getting close to the protected unit and overpass certain acceleration, speed and distance limits regarding the front and the re ar bumpers of the protected vehicle; modern vehicles have front bumpers which are expensive and difficult to repair, the device also preventing rear and front lights from being damaged upon a collision when the vehicle is parked. The device has a microcontroller that automatically selects the suitable form for activating each of the peripheral elements such as horn and lights, also has a circuit that activates and deactivates the operation of the inventive device at will or in some cases in a pre-programmed manner; the original functions of the vehicle are not altered, the inventive device being electrically transparent for the original circuits of the vehicle. Esta invención consiste en un dispositivo que se puede instalar en vehículos equipados con unidades ultrasónicas de medición de distancia con objeto de brindarle protección al mismo cuando éste se encuentra estacionado, para prevenir que otros vehículos que realicen maniobras de estacionamiento o de posicionamiento lo impacten. Los equipos originales de ultrasonido, no están diseñados para proporcionar protección una vez que el conductor retira la llave de ignición, de manera tal que las unidades de medición ultrasónica quedan apagadas y completamente inoperantes cuando el automóvil se encuentra estacionado y apagado; el dispositivo de protección contra colisiones para vehículos automotores estacionados, se instala en la red de interconexiones eléctricas del vehículo de manera tal que el vehículo conserva todas las fun
