置。 A vehicle speed detection means, an inter-vehicle distance detection means consisting of a laser/radar head, an own vehicle speed calculation means for calculating the own vehicle speed based on a vehicle speed signal from the vehicle speed detection means, and an own vehicle speed calculation means for calculating the own vehicle speed based on a signal from the inter-vehicle distance detection means. forward vehicle speed calculation means for calculating the forward vehicle speed based on the signals from the own vehicle speed calculation means and the relative speed calculation means; and a forward vehicle speed calculation means for calculating the safe inter-vehicle distance based on the own vehicle speed. Rear-end collision of a vehicle equipped with a safe inter-vehicle distance calculation means and an alarm generation determination means that compares the safe inter-vehicle distance and the actual inter-vehicle distance between the vehicle in front and the own vehicle and issues an alarm when the actual inter-vehicle distance is smaller than the safe inter-vehicle distance. In the alarm device, the alarm occurrence determination means outputs a low cycle blinking drive signal to the alarm lamp in the primary alarm cause area and a high cycle blinking drive signal to the alarm lamp in the secondary alarm cause area. A rear-end collision warning device for a vehicle, characterized in that it is configured as a means.
