Abstract
A suspension control device includes a wheel grip state estimation device for estimating grip state of vehicle wheels based on variations of aligning torque of wheels to be steered, a vehicle rolling control device for controlling vehicle rolling, and a control parameter setting device for setting a control parameter of the vehicle rolling control device based on at least estimated grip state of the wheel grip state estimation device.
Claims21
A suspension control device comprising:
- a wheel grip state estimation means for estimating a grip state of vehicle wheels based on variations of aligning torque of wheels to be steered, the grip state representing the degree of a lateral force that tires of the vehicle wheels generate relative to the maximum degree of the lateral force that the tires generate with a percentage of allowance to a limit;
- aligning torque estimation means for estimating the aligning torque on the basis of a pneumatic trail;
- a vehicle rolling control means for controlling vehicle rolling;
- and
- a control parameter setting means for setting a control parameter of the vehicle rolling control means based on at least estimated grip state of the wheel grip state estimation means.
