Provided is an examination method for a damping force variable mechanism, the examination method including: an operation step of operating a damper in a state in which the damper is installed in a vehicle, the damper being provided with a damping force variable mechanism that changes a damping force according to an input current (an example of a signal); and a detection step of detecting an induction current (an example of an output from the vehicle) from the damping force variable mechanism of the damper installed in the vehicle, wherein a detection device that performs the operation of the detection step is provided. Thus, the damping force variable mechanism of a pressure damping device can be examined in a state in which the damping force variable mechanism is installed in the vehicle.

Method and system for inspecting damping force variable mechanism, and method for inspecting pressure damping device

A suspension controller includes a wheel speed sensor that detects the wheel speed of each wheel, a basic input amount calculating unit that calculates the basic input amount of the vehicle on the basis of a wheel speed variation detected by the wheel speed sensor, a state amount calculating unit that calculates the state amount of the vehicle by inputting the basic input amount to a vehicle model representing the motion of the vehicle, and a damper controlling unit that controls the damping force of a damping-force-variable damper on the basis of the calculated state amount. If the wheel speed variation detected by the wheel speed sensor decreases below zero by a predetermined value or more on the minus side, the vertical load of the wheel is considered to be decreased, and the damping force is controlled to be greater than before the decrease.
