PURPOSE:To simplify the constitution of a circuit, by providing two vehicle height detecting means for issuing vehicle height detected signals in the same level, and delaying only the output signal of the first vehicle height detecting means to judge discriminate the height of the vehicle. CONSTITUTION:The vehicle height detector 100 consists of photosensors 101, 102 comprising luminescent diodes and photo transistors, an output signal of the photosensor 101 is applied to a delay circuit 210 of the vehicle height adjusting and controlling apparatus, and an output signal (b) of the photosensor 102 and an output signal of the delay circuit 210 are applied to a vehicle height judging gate circuit 220. Thus when an output end Q3 of a counter CO1 of the delay circuit 210 and the output signal (b) of the photosensor 102 become H, the vehicle height is judged as high, while when the output end Q3 of the counter CO1 becomes H and the output signal (b) of the photosensor 102 becomes L, the vehicle height is judged as low. |
