Claims

[Scope of utility model registration request]

In a vehicle suspension that incorporates a shock absorber with a damping force switching mechanism and an air spring chamber with a spring constant switching mechanism, there is an accelerator opening sensor that detects the opening of the accelerator pedal, and an accelerator opening sensor that detects the opening of the accelerator pedal. A differentiation circuit that differentiates the detection signal and a comparator that outputs a high level signal when the accelerator opening/closing speed signal from the differentiation circuit is equal to or higher than a predetermined value are provided. A control means for supplying a control signal to the damping force switching mechanism or the spring constant switching mechanism in order to control the suspension to a hard state by increasing at least one of the damping force of the shock absorber and the spring constant of the air spring chamber. A suspension device for a vehicle, characterized by being provided with.
