Method for chassis control of a motor vehicle, and device for the performance thereof

摘要

In a method for chassis control of a motor vehicle which has at least one wheel suspension, a vehicle body, and a shock absorber having a rebound stage, whose stiffness is adjustable, and a compression stage, whose stiffness is adjustable, the stiffness of the compression stage is changed for a compressive load of the shock absorber generated by a specific vehicle body movement, and the stiffness of the rebound stage is additionally changed for a subsequently following tensile load of the shock absorber generated by the specific vehicle body movement, or the stiffness of the rebound stage is changed for a tensile load of the shock absorber generated by a specific vehicle body movement, and the stiffness of the compression stage is additionally changed for a subsequently following compressive load of the shock absorber generated by the specific vehicle body movement.

1. A method for chassis control of a motor vehicle, comprising:
controlling at least one shock absorber provided between a wheel and a body of the motor vehicle, wherein the shock absorber has a rebound stage with adjustable stiffness and a compression stage with adjustable stiffness, wherein the controlling of the shock absorber includes one of: i) increasing the stiffness of only the compression stage for an initial compressive load of the shock absorber generated by a specified first movement of the body of the vehicle, and thereafter, as a function of a first subsequent movement generated by a subsequent tensile load of the shock absorber immediately following the initial compressive load generated by the specified first movement, increasing the stiffness of only the rebound stage; or ii) increasing the stiffness of only the rebound stage for an initial tensile load of the shock absorber generated by a specified second movement of the body of the vehicle, and thereafter, as a function of a second subsequent movement generated by a subsequent compressive load of the shock absorber immediately following the initial tensile load generated by the specified second movement, increasing the stiffness of only the compression stage, wherein the shock absorber has at least one first valve for adjusting the stiffness of the compression stage and at least one second valve for adjusting the stiffness of the rebound stage, and wherein the controlling of the shock absorber includes one of: i) switching the first valve to increase the stiffness of only the compression stage before the initial compressive load of the shock absorber generated by the specified first movement of the body of the vehicle, and switching the second valve during the occurrence of the initial compressive load to increase the stiffness of only the rebound stage for the subsequent tensile load of the shock absorber immediately following the initial compressive load generated by the specified first movement; or ii) switching the second valve to increase the stiffness of only the rebound stage before the initial tensile load of the shock absorber generated by the specified second movement of the body of the vehicle, and switching the first valve during the occurrence of the initial tensile load to increase the stiffness of only the compression stage for the subsequent compressive load of the shock absorber immediately following the initial tensile load generated by the specified second movement.
