Abstract

Fremgangsmåte for varsling av en bilfører ved fare for påkjørsel mot forankjørende bil når avstanden til forankjørende bil minsker hurtigere enn en på forhånd fastlagt grenseverdi, ved å søke, registrere og overvåke optisk et karakteristisk delbilde av en foran- kjørende bil, eksempelvis skyggen av bilen mot gatelegemet, et karakteristisk bilde av en bils bakre del, en horison- tal linje langs bilens underside, el.l., å overføre de optisk avleste data til data i en mikroprosessor, å forfølge delbildets bevegelse opp, ned, til begge sider og forminskende og forstørrende, og å avgi signal til en alarmanordning dersom delbildet blir større fra en gitt minimumsstørrelse og med en gitt has- tighet. En anordning for varsling av en bilfører omfatter en mikroprosessor som mottar signaler fra en optisk registrer- ingsanordning rettet mot trafikkbildet forover, hvor mikroprosessoren gjenkjen- ner et karakteristisk bilde av en foran- kjørende bil, mikroprosessoren sender signal til en alarmanordning dersom bildets størrelse øker fra en gitt mini- mumsstørrelse med en gitt minste- hastighet og alarmanordningen avgir et signal til føreren.Procedure for Alerting a Driver in the event of a danger of collision with the front car when the distance to the front car decreases faster than a predetermined limit value, by searching, registering and monitoring optically a characteristic sub-picture of a passing car, for example the shadow of the car towards the street body, a characteristic image of the rear of a car, a horizontal line along the underside of the car, or the like, to transmit the optically read data to data in a microprocessor, to track the movement of the sub-image up, down, to both sides and diminishing and magnifying, and emitting a signal to an alarm device if the sub-image becomes larger from a given minimum size and at a given speed. A car driver warning device comprises a microprocessor which receives signals from an optical recording device directed at the forward traffic image, where the microprocessor recognizes a characteristic image of a passing vehicle, the microprocessor sends an alarm to an alarm device if the image size increases from a given minimum size with a given minimum speed and the alarm device gives a signal to the driver.
