Patent Images
1. 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.
