Abstract: A vehicle-height adjusting system includes: vehicle-height adjusting actuators each for adjusting a vehicle height for a corresponding one of wheels; a pressure medium supplier for supplying a pressure medium from a tank to each of the vehicle-height adjusting actuators; and a vehicle height adjuster for adjusting the vehicle height for each wheel. The vehicle-height adjusting actuators include a left vehicle-height adjusting actuator and a right vehicle-height adjusting actuator. The vehicle height adjuster includes a supply amount controller configured to control the pressure medium supplier such that substantially the same amount of the pressure medium is to be supplied from the tank to the left vehicle-height adjusting actuator and the right vehicle-height adjusting actuator, when at least one of the wheels is in contact with an uneven road surface.

Abstract: There is provided a vehicle abnormality detection method detecting an abnormal state in which a high temperature occurs due to maladjustment of a vehicle bearing mechanism section or vehicle brake mechanism section, and a device thereof and a sensor unit thereof. By use of the sensor unit 100 mounted in a rim 31, an air temperature within a tire 2 is sensed as a first temperature and a temperature (second temperature) of the rim 31 is sensed as a temperature related to at least one of a temperature of the vehicle bearing mechanism section and a temperature of the vehicle brake mechanism section 40. Then a temperature difference between the first and second temperatures is calculated and when the temperature difference is a predetermined value or more, it is determined that an abnormality has occurred in the vehicle bearing mechanism section or vehicle brake mechanism section 40. The abnormality is thus detected.

Abstract: A method for controlling or regulating a compressor 4 that can be switched on and off on demand, wherein a control unit 6 that switches the compressor 4 on and off is provided with the compressor. In a method of this type, it must be ensured that the compressor 4 is not damaged due to overheating. This is attained due to the fact that the control unit 6 operates the compressor 4 continuously during a regulating process until a limiting value is reached, and that said control unit operates the compressor in a cyclic manner once the limiting value is reached. This method makes it possible to complete regulating processes even if a critical limiting value is already reached.

Abstract: A vehicle suspension system may include hydraulic actuators, first and second conduits, and first and second switch valves. Each actuator includes a cylinder and a piston that divides an interior of the cylinder into compression and rebound chambers. First and third ports of each cylinder are openings to the rebound chamber. Second and fourth ports of each cylinder are openings to the compression chamber. The first conduit connects the third port of a first actuator with the fourth port of a second actuator. The second conduit fluidly connects the third port of the second actuator with the fourth port of the first actuator. The first switch valve is connected to the first and second ports of the first one of the hydraulic actuators. The second switch valve is connected to the first and second ports of the second one of the hydraulic actuators.
