PURPOSE:To secure running stability in an automobile, by preventing a suspension from coming into a state that the front wheel side is soft whereas the rear wheel side is hard when anything trouble happens in a suspension system, in case of the said suspension which variably controls the suspension characteristic according to car driving conditions. CONSTITUTION:In the case where a suspension system at the front wheel side fails to normally operate whereas a suspension system at the rear wheel side operates normally when select signals K and L are outputted to each of front- and- rear-wheel-side select switches 52 and 53 from a control logic part 51 in order to select a suspension characteristic in suspension systems at both front and rear wheels from soft to hard, the select switch 52 at the front wheel side does not complete its select motion to 'hard' so that a continuous rating current still remains energized. This trouble is detected by a current detecting circuit 55, transmitting a trouble detection signal M to the control logic part 51. With this constitution, the control logic part 51 outputs these select signal K and L having a soft signal outputted to each of switches 52 and 53, thus the suspension characteristic of each suspension is brought back to a state of being soft. |
