Abstract
PURPOSE:To prevent bottoming during running on the bad road in such a way that running on the bad road is discriminated when the actual vehicle height exceeds the predetermined discriminating level, and its frequency exceeds the predetermined value, and the vehicle height is automatically controlled at relatively higher position for running on the road. CONSTITUTION:After output from a vehicle height sensor 10 which is installed in reference to each wheel is processed through a filter circuit 20, a comparator 22 and an all-wave rectifier 26, it is transmitted to a comparator 28, and compared with output from an F/V converter 30 in response to the speed through a speed sensor 12, namely with signals in the bad road discriminating level alpha. And after signals in the outputs which exceed said level d of the all-wave rectifier 26 are processed through a wave-form shaping device 32 and an integrator 34, they are transmitted to a comparator 40 in accordance with synchronizing signals from a synchronizing circuit 36. Hereby, it is compared with the bad road discriminating level beta from an F/V converter 42, and when it exceeds this level beta, it is discriminated to be a bad road, then a vehicle height regulator 16 is properly controlled in such a way that signals at the target vehicle height value to raise the vehicle height are given as output through an F/V converter 48.
