Abstract
A vehicle periphery monitoring device includes a transmitting circuit for generating a transmission wave, an antenna installed on the periphery or in the interior of a door mirror of a subject vehicle for radiating the transmission wave generated from the transmitting circuit as a formed beam having a directivity which propagates over a region expanding over an adjacent lane area from side portions of the subject vehicle toward the rear portion thereof, a receiving circuit for receiving a reflected wave from an object which is in the periphery of the subject vehicle through an antenna , an arithmetically operating circuit for arithmetically operating a distance between the subject vehicle and the object on the basis of a period of time required since the transmission wave generated from the transmitting circuit is radiated from the antenna until the transmission wave is reflected by the object and received by the receiving circuit and arithmetically operating a relative velocity from Doppler frequency of a received electric wave or a value of differential from an arithmetically operated distance to judge the risk of collision with the object on the basis of those arithmetically operated results, and LEDs and for announcing the judgement result of the arithmetically operating circuit to a driver in response to the risk.
