自動車の追突警報装置。 The vehicle speed calculation circuit includes vehicle speed detection means and distance detection means consisting of a laser/radar head, and calculates the vehicle speed based on the vehicle speed signal from the vehicle speed detection means, and calculates the safe inter-vehicle distance from the vehicle speed. The present invention is characterized by being provided with a braking distance calculation circuit that calculates a dangerous inter-vehicle distance by multiplying the vehicle speed by a fixed rate, and an alarm occurrence determination circuit that determines the occurrence of two or more different types of audio warnings depending on the safe inter-vehicle distance and the dangerous inter-vehicle distance. Rear-end collision warning system for cars.
