<p>PURPOSE:To inform a vehicle operational state correctly to a driver of a succeeding car or the like by constituting plural different displays corresponding to respective detected results so as to be selectively performed on the basis of these detected results of a travel speed detecting means and an adjustable speed detecting means. CONSTITUTION:Output of an adjustable speed detecting sensor 2, a brake operation detecting sensor 4 and a travel speed detecting sensor 6 are, respectively, inputted into a microprocessing unit 1 via voltage conversion circuits 3, 5, 7 and so on, and according to the detected result processed hereat, a display state at display bodies (16 X 16 dot matrix LED) 12a, 12b is controlled by a controller 9 via low drivers 11a, 11b and column drivers 14a, 14b. In brief, when a fact that vehicle speed is going up is detected, a character of 'acceleration' is displayed, and when a fact that it is in a state of being braked is detected, a character of 'stoppage' is displayed instead. In addition, when it is detected that speed is in effectiveness, a character of 'deceleration' is displayed.</p> |
