Claims

[Scope of utility model registration request]

A suspension unit having a state switching mechanism that increases or decreases at least one of the damping force or the spring constant, a steering wheel angular velocity sensor that detects the steering wheel angular velocity, a steering direction sensor that detects the steering direction, and a suspension unit that is provided between the left wheel side of the vehicle and the vehicle body side. A left vehicle height sensor that detects the left vehicle height based on the relative displacement between the two, a right vehicle height sensor that is provided between the right wheel side of the vehicle and the vehicle body and that detects the right vehicle height based on the relative displacement between the two, and the above-mentioned steering wheel angular velocity. The steering wheel angular velocity is calculated from the detection signal of the sensor, and when the steering wheel angular velocity exceeds a preset value, a hard state switching signal is supplied to the state switching mechanism to set the suspension unit to the hard state, and the steering wheel angular velocity is After the hard state switching signal is supplied, the steering direction, left vehicle height, and right vehicle height are calculated based on the detection signals from the steering direction sensor, the left vehicle height sensor, and the right vehicle height sensor, respectively. As long as the roll direction of the vehicle determined by the left vehicle height and the right vehicle height corresponds at least to the steering direction, a control signal that maintains the hard state regardless of the steering wheel angular velocity is switched to the above state. A suspension device for a vehicle, characterized by comprising a control means for supplying power to a mechanism.
