VEHICLE CONTROL DEVICE, AND VEHICLE CONTROL METHOD
摘要:
A vehicle control device includes a sensor and a controller. The sensor detects wheel speed. The controller estimates sprung mass state based on detected information in a prescribed frequency range. The controller controls a variable-damping force shock absorber to bring the estimated sprung mass state to a target sprung mass state. The controller estimates wheel rim braking/drive torque acting on a wheel. The controller determines the estimation accuracy of the sprung mass state has deteriorated when a rate of change of a stationary component extracted from components of wheel rim braking/drive torque acting on a wheel is detected to equal or exceed a prescribed value. The controller controls the variable-damping force shock absorber to a more limited extent than when the estimation accuracy has not deteriorated.
