摘　　要：为优化防抱制动系统(ABS)在转向和制动联合工况下的控制策略,需要识别车辆转向状态。选取适于ABS应用的转向参数:车速、转向方向和前轮转角,通过对比转向参数的直接与间接测量技术,根据四轮车辆转向运动学原理,结合二自由度车辆模型的稳态转向特性,研究了利用ABS轮速信号和控制信息的转向参数估算算法。运用稳态回转试验和制动转向试验进行了系统测试,结果表明参数估算具有较好的精度。For the purpose of optimizing control strategy of anti-lock braking system（ABS） under the steering and braking combined working condition,the vehicle steering state should be identified.The steering parameters adapted to ABS application were selected which were composed of vehicle velocity,turning direction and steering angle.The applied direct and indirect measure technologies were compared.According to the principle of kinematics of four-wheel vehicle and stable steering characteristic of two-degree-of-freedom vehicle model,the steering parameters estimation algorithms using ABS wheel speed and control information were researched.System test was carried out by the experiment of the steady static circular running and braked steering.The test results showed good accuracy of the parameters estimation.
