DEVICE FOR PREVENTION OF COLLISION OF CAR WITH OBSTACLE Russian patent published in 2009 - IPC G01S13/93 

FIELD: physics, measuring.

SUBSTANCE: device concerns to location systems of maintenance of car safety during its motion. The offered device contains a gang of the identical integrated modules including not scanning, astigmatic, send-receive optical system which simultaneously shapes directional diagrammes pulsing anallactic and the continuous Doppler optical locators. The temporary selectors oozing corresponding intervals of a distance to a hindrance are connected to an exit pulsing anallactic optical locator of each module. The band-pass frequency filters oozing intervals of the relative velocities of rapprochement with a hindrance are connected to an exit of the continuous Doppler optical locator of the module. Outputs of temporary selectors and band-pass frequency filters of each module are connected to system of processing of the information in which the information on natural velocity of the car also arrives. Outputs of the information processing system are connected to the systems of the light and sound warning of the driver about presence, direction and distance to an obstacle, and also to the onboard computer driving in parameters of the car motion.

EFFECT: prevention of collision of the car with an obstacle using warning of the driver about an obstacle.
