Claims

[Scope of utility model registration request]

A vehicle speed detection means for detecting the speed of the own vehicle, a vehicle speed calculation means for calculating the vehicle speed based on the vehicle speed signal from the vehicle speed detection means, and a laser/radar head provided at the rear of the vehicle. distance detection means; inter-vehicle distance calculation means for calculating an inter-vehicle distance based on a distance signal from the inter-vehicle distance detection means; and calculation of the relative speed between the own vehicle and the following vehicle based on the signal from the inter-vehicle distance calculation means. a rear vehicle speed calculation means for calculating a rear vehicle speed based on signals from the own vehicle speed calculation means and the relative speed calculation means; a safe following distance calculation means for calculating a safe following distance between the vehicle and the vehicle;
A warning means for calling attention to the driver of the vehicle behind compares the actual inter-vehicle distance detected by the inter-vehicle distance detection means with the safe inter-vehicle distance, and when the actual inter-vehicle distance is shorter than the safe inter-vehicle distance, the caution is issued. 1. A rear-end collision warning device for a vehicle, comprising: warning determining means for determining whether a warning means should be activated.
