摘要: A shock damper is disposed between a vehicle body side and a wheel side. A suspension control device calculates a damping force of the shock damper on the basis of vehicle height information and controls the damping force. A steering system includes an electric motor and a steering control device that controls the electric motor, and assists steering effort of the driver through the electric motor. The suspension control device calculates the vibration generated in a steering on the basis of a detected value of a vehicle height sensor and creates a signal for generating steering torque that reduces the generated vibration. The suspension control device outputs the created signal to the steering control device. Steering torque for cancelling steering vibration is accordingly outputted from the electric motor of the steering system.

摘要: A vehicle height adjustment device includes: vehicle height adjustment actuators provided to at least a pair of front wheels or a pair of rear wheels of a vehicle, and configured to adjust a vehicle height defined by a distance between the wheels and a vehicle body; an actuator control device configured to control the vehicle height adjustment actuators such that the vehicle height approximates to a target vehicle height; and a detection device configured to detect a physical quantity which varies as upward or downward movement of the vehicle body is restricted due to contact with an external contacted object. The actuator control device stops upward or downward movement of the vehicle body, and switches to movement in an opposite direction based on a detected value of the detection device, when the determination that the movement of the vehicle body is restricted is made by the detection device.

摘要: The invention detects at least either one of a supply fault and a ground fault distinctively from a disconnection. A compressor relay 22 is placed between a battery 21 and an air compressor module 5. The compressor relay 22 controls the drive and stop of the air compressor module 5. A compressor driver 26 outputs a drive signal to the compressor relay 22. A ground-side voltage monitor 2S detects the drive voltage of the compressor relay 22. A pressure sensor 17 detects air pressure in a discharge side of the air compressor module 5. A microcomputer 30 of a controller 25 detects a ground fault and a disconnection of the drive signal of the compressor 22 distinctively from each other on the basis of a voltage value Vg detected by the ground-side voltage monitor 28 and a pressure valve P detected by the pressure sensor 17.

摘要: A controller 10 as a generation mechanism control portion includes a base control portion 15 that determines a lower limit value on an instruction signal (i.e., a base instruction value) that serves as a lower limit on a force to be generated by a variable damper 6 (a force generation mechanism) according to at least a running speed of a vehicle. The base control portion 15 corrects the base instruction value by a base instruction value calculation portion 28 based on a result of a determination about a road surface output from a road surface determination portion 26 (i.e., a result of detection by a road surface state detection portion). A vehicle behavior control apparatus is configured to variably control a damping force characteristic of the variable damper 6 according to a road surface state with use of an instruction value output from the controller 10.
