Title: Air suspension control device
Inventor: MISAWA MASAYA
IPC: B60G17/015
Filed: 1997-05-24
Abstract: PROBLEM TO BE SOLVED: To eliminate wasteful consumption of air, and improve the operating stability by avoiding air-control of air springs in relation to the short-time change in car height, which is generated during the car travel and immediately restored. SOLUTION: The car heights are sampling-detected by a car height sensor 11 are stored in a detected car height storage-memory 17. Air-control of air springs 12A, 12B is performed by controlling solenoid valves 9A, 9B through a control unit 16. Whether a car is stopped or travels, is distinguished by detection signals from a car-speed sensor 8. When the car is stopped, the detected car heights are compared to a reference car height, and air-controlled so as to reach the reference car height. When the car is running, an average car height within a specified period of time is determined based on the stored detected car height values, and air-controlled to reach the reference car height. Thus, the need for allowing the air-control to respond to the change in the car height, which is immediately restored, is reduced.

Abstract: PURPOSE:To reduce greatly the load of each processor which is needed for circuit switching by making a circuit switching device to bear entirely the decision and the execution of switching and connecting a circuit. CONSTITUTION:The 1st information of logic 0 is written periodically to the 1st register 24 as long as both processors 21-0 and 21-1 are normal.

It is finally judged that the corresponding processor operates normally as long as a relevant bit is set at the logic 0 in case the logic 1 is written to the device 22. Now if a processor 21-0 has a fault at a time point t4, the device 22 starts a prescribed circuit switching action since it is detected that the corresponding bit is kept at 1 when the logic 1 is written to the register 24 by the device at a time point t5.
