Abstract

PURPOSE:To comfortably drive a car, by automatically controlling the height of the car as travelling until the car becomes to a standard attitude while stabilizing an attitude of a car body that is travelling even when starting just after loading freights and even in the operation of any bad roads or unfavorable conditions. CONSTITUTION:An input change discriminating circuit 32 is mounted which is used for branching vibration into vibration only in single ranges in each car height range of a high level, a standard level and a low level and vibration extending over plural ranges in response to signals from sensors S1, S2 for detecting locations between a car body and an axle, which are mounted to suspension systems 14. A time counter 33 for monitoring durability within a fixed time of vibration in single ranges, a durability monitor circuit 34 and a pattern forming circuit 36 for forming the patterns of vibration in plural ranges are connected to the circuit 32. A pattern durability decision circuit 37, a time counter 38 and a durability monitor circuit 39 are successively connected to the circuit 36, and a control circuit 20 of valves 18, 19 is controlled by car height decision signals by means of a range de- cision circuit 35.
