置。[Scope of claim for utility model registration] (1) The vehicle has an ultrasonic distance measuring device, a safe following distance calculating device, and a warning device at the rear of the vehicle, and inputs the vehicle speed signal from the vehicle speed sensor to the safe following distance calculating device. , the following distance signal from the ultrasonic distance measuring device is input to the safe following distance calculating device, the output signal of the safe following distance calculating device is input to the warning device, and the following distance is determined as the safe following distance detected by the safe following distance calculating device. This is a warning device for road vehicles that activates a warning device on condition that the following distance is smaller than the distance and the vehicle speed is equal to or higher than a reference value. (2) The inter-vehicle distance insufficient warning device according to claim 1, wherein the safe inter-vehicle distance calculation device includes an arithmetic circuit that calculates the safe inter-vehicle distance based on vehicle speed. (3) The inter-vehicle distance insufficient warning device according to claim 1, wherein the safe inter-vehicle distance calculation device has a circuit for storing and reading out a safe inter-vehicle distance corresponding to the vehicle speed. (4) The insufficient following distance warning device according to claim 1, wherein the warning device is an electric character display device. (5) The insufficient following distance warning device according to claim 4, wherein the warning device is a flashing display board. (6) The inter-vehicle distance insufficient warning device according to claim 5, wherein the blinking interval is shortened as the inter-vehicle distance is shorter than the safe inter-vehicle distance. (7) The insufficient inter-vehicle distance warning device according to claim 1, wherein a condition is added that the vehicle speed is equal to or higher than the reference value by turning on the power when the vehicle speed is equal to or higher than the reference value.
