Document Type and Number:
Japanese Patent JP7450469
Kind Code:
B2
Abstract:
To appropriately determine a timing of finishing damper control.SOLUTION: A damper control device comprises: a wheel speed sensor that obtains a wheel speed of a vehicle; a state quantity estimating part that estimates a state quantity of the vehicle using at least a value from the wheel speed sensor; and a control part that determines a control quantity of a damping-force variable damper on the basis of the value from the wheel speed sensor and the state quantity, which performs processing of determining whether or not wheel speed variations, variations of the wheel speed are over a predetermined threshold and when making excess-determination determining that the variations are over the threshold, determines the control quantity of the damping-force variable damper provided in the vehicle in consideration of the excess determination, after the excess determination is made until a predetermined condition determined based on the wheel speed variations is satisfied.SELECTED DRAWING: Figure 2
