摘　　要：为了提高电动轮汽车在紧急制动过程中的稳定性,提出了一种基于实时计算车轮滑移率的再生制动与液压制动协调控制防抱死策略。基于重新构型的液压制动系统,根据轮速和车速计算汽车瞬时纵向滑移率,并以其为控制目标,设定一套滑移率门限值,通过降低电机转矩来实现制动防抱死控制。在AMESim软件中建立相应的15自由度整车模型,在Simulink中建立防抱死控制策略模型,并在低、中、高3种不同附着路面上进行仿真,结果表明,本文制定的控制策略能够在满足汽车在高效回收制动能量的同时防止车轮抱死,保证了车辆的制动稳定性。A coordinated control system is developed for the regenerative and hydraulic braking systems in electric-wheel vehicle.The control system is based on real calculation of wheel slip ratio model to improve the stability of the electric-wheel vehicle in emergency braking process.Antilock braking control is realized by reducing the motor torque with setting a series of threshold values of slip ratio,which are compared with instantaneous longitudinal slip ratio calculated according to wheel speed,based on a redesign of hydraulic braking system.A 15 DOF vehicle model is established in AMESim and Anti-lock Braking System(ABS)control model is established in Simulink.Simulation is carried out at low,middle and high grade of adhesion coefficient of the road.Results show that the proposed control strategy can prevent the wheel from locking as efficient recovery of braking energy,and ensure the braking stability of the vehicle.
