Abstract

PURPOSE:To make a driver concentrate his attention to surroundings without informing him of very small change in the speed and to make the renewal of indication follow the travelling speed, by indicating each travelling speed when the travelling speed different from an indicated value is detected in prescribed times. CONSTITUTION:When the travelling speed takes a prescribed value, a signal is delivered from a vehicle-speed sensor 10 to a processing unit 12 and the number of the indicating elements 17 of an indication panel 18 which is brought into a state of indication in accordance with the travelling speed is memorized, while the value of the difference obtained by subtracting a measured value from an initial value is also memorized. And, in the case when this value of the difference is not within the range of a set value, the indicating element 17 of the indicaion panel 15 is made to operate by a minimum unit of indication, whereby an indication in accordance with the travelling speed detected is conducted.
