Control system, the one active rear wheel steering for a vehicle has the effect by the use of an estimate of the vehicle dynamics parameters

摘要

Control system (30), the one active rear wheel steering for a vehicle (10), wherein the system (30) comprises:a subsystem (40) for the estimation of the vehicle dynamics parameters, the input signals (v_x, δ_F, δ_R, Ω, ay) responds, wherein the subsystem (40) is a parameter estimation algorithm for estimating of the vehicle dynamics parameters (d_F, D_R) based on the input signals (v_x, δ_F, δ_R, Ω, ay) is used, the estimated vehicle dynamics parameters (d_F, D_R) with the rated - vehicle dynamics parameters (d_F⁰, D_R⁰) compares and difference signals (δd_F, Δd_R) to be produced, which, the deviation between the estimated vehicle dynamics parameters (d_F, D_R) and the rated - vehicle dynamics parameters (d_F⁰, D_R⁰) indicating;a control method according to the - subsystem (34) with an open control loop for generating a steering control signal (δ_Ol) for an open control loop, wherein the subsystem (34) to a driving speed signal (v_x), a front wheel - steering angle signal (δ_F) and the difference signals (δd_F, Δd_R) responds, a look-up table (50) for an open control circuit includes, in order to use of the vehicle speed signal (v_x) and of the front wheel - steering-angle signal (6f) a nom - steering angle signal (δ_Ol⁰) to produce for an open control loop, and further comprising an adaptive compensation - subsystem (60) for an open control loop..
