<p>PURPOSE:To provide a display means capable of easily announcing an alarm when a situation where an alarm is transmitted to the driver of a subsequent car is produced during running of a vehicle. CONSTITUTION:A laser radar head 2 to detect a distance between a self-car and a subsequent car, a control unit 1 to compute a relative approach speed between the self-car and the subsequent car, and a lamp control unit 1 to light ON a unit flasher 5 when a relative relation between the self-car and the subsequent car enters the given alarm region of a two-dimensional region based on the distance between the cars and the relative approach speed are provided. The control unit 1 to light OFF the lamp when after the lamp is lighted ON, a relative relation between the self-car and the subsequent car is within a given distance between the cars for a given time or more, the speed of the self-car is reduced to a value lower than a given value, and a relative approach speed is reduced to a value lower than a given value is provided.</p> |
