<p>PURPOSE:To smoothen the operating state of a vehicle and to reduce power consumption amount by simultaneously displaying not only a blocked zone existing in the vehicle but also speed limit information of the front blocked zone by an internal signaling unit in the vehicle. CONSTITUTION:Signal lobic units 1ATL, 2ATL provided at every blocked zones 1T, 2T respectively apply speed limit information in response to vehicle detection information to inputs A of selectors 1SEL, 2SEL. On the other hand, the output of a signal logic unit 2ATL is applied through a coder 2COD to an input B of the selector 1SEL. Since the selector 1SEL repeats the selection of the inputs A, B in response to a switching pulse from a pulse generator 1PG, the selector produces speed limit information of the blocked zone 1T when selecting the input A and speed limit information of the blocked zone 2T when selecting the input B.</p> |
