The invention provides a wheel clamping stagnation working condition identification optimization method and electric power steering control equipment, which are used for optimizing an angle control method of an EPS responding to an upper computer under an EPS automatic parking working condition, carrying out dynamic limitation according to a proportional control output value, and carrying out identification optimization on the wheel clamping stagnation working condition according to a control error state of a system under the condition that the system is saturated. When the output of the proportional sum integrator is greater than the system output, the excessive part is subtracted from the integral part, so that the problem of continuous integration caused by control over supersaturation is solved; according to the method, the function of recognizing the wheel clamping stagnation working condition through the EPS in the automatic parking process is achieved, so that unnecessary rising of assistance current is reduced, the problem that the system enters clamping stagnation protection or thermal integration protection in advance is avoided, and the target angle control response performance and the thermal durability of the EPS system are improved.

    本发明提供了一种车轮卡滞工况识别优化方法和电动助力转向控制设备,用于EPS自动泊车工况下,通过对EPS响应上位机的角度控制方法进行优化,根据比例控制输出值进行动态限制,根据系统的控制误差状态,在系统饱和的情况下,比例和积分器的输出大于系统输出的时候,积分部分减掉多出的部分,从而解决控制过饱和导致的连续积分问题;实现了在自动泊车中通过EPS对车轮卡滞工况进行识别的功能,从而降低了助力电流的非必要上升,避免了导致系统提前进入卡滞保护或者热积分保护的问题,提高了EPS系统的目标角度控制响应性能和热耐久性能。
