Cascade Tire-force Estimation Method Based on Sliding-mode Observer
摘要
Abstract
We present a novel cascade tire-force estimation framework based on the sliding-mode observer method. We estimate each longitudinal tire force on the basis of the single-wheel vehicle model,which uses the angular velocity and driving torque of the wheel as inputs.Then,we apply a simplified 2-degrees-of-freedom (2-DOF)vehicle dynamic model to design the front and rear lateral-tire-force sliding-mode observer,and use the estimated longitudinal tire forces,the front-wheel angle,the lateral acceleration,and the yaw rate as the ob-server inputs.We experimentally evaulate the proposed tire-force estimation method on the high-precision ve-hicle dynamic software,veDYNA,and compare the estimation results with those of the extended Kalman filter (EKF)method.The results demonstrate that the sliding-mode observer has relatively higher accuracy in esti-mating tire forces.关键词
