Title:
VEHICLE BODY ATTITUDE ADJUSTMENT-BASED METHOD FOR CONTROLLING ADJUSTABLE DAMPING SUSPENSION
Document Type and Number:
WIPO Patent Application WO/2021/259004
Kind Code:
A1
Abstract:
A vehicle body attitude adjustment-based method for controlling an adjustable damping suspension. A suspension comprises a first shock absorber (1), a second shock absorber (2), a third shock absorber (3), and a fourth shock absorber (4) that are connected to a vehicle body (100) as well as to a left front wheel, a right front wheel, a left rear wheel, and a right rear wheel, respectively. The control method comprises: obtaining the center of mass (101) of the vehicle body and the motion states of wheel assemblies; determining the total target damping force of the suspension; obtaining the attitude of the vehicle body; determining a sub-target damping force of each shock absorber; calculating a target damping coefficient of each shock absorber according to the respective sub-target damping force of each shock absorber, the center of mass of the vehicle body, and the motion states of the wheel assemblies; and obtaining an actual target damping coefficient of each shock absorber according to the respective damping coefficient adjustment range of each shock absorber.
