The invention relates to a steering system control strategy which is used for solving the problems of stability and safety of a steering system. Specifically, in the system adjusting process, whether the system works normally or not is judged by monitoring a vehicle running speed signal, a steering wheel corner signal, a wheel corner signal, pressure signals of all parts of the system and the like, if yes, whether the rotating speed of the power take-off opening of a motor or an engine meets the use requirement or not is checked, and if yes, the control valve group charges and discharges oil to the steering oil cylinder, and acquires the wheel corner signal and the working pressure signal at each position in real time; if the rotating speed of the power take-off port of the motor or the engine does not meet the use requirement, the emergency steering system is started, the energy accumulator is used for providing compensation pressure for the system to guarantee normal work, whether the work pressure and the wheel turning angle meet the use requirement or not is further judged, if the target position is reached, the automatic centering function is executed, and steering is finished; and if the steering oil cylinder does not reach the target position, oil charging and discharging of the steering oil cylinder are continuously adjusted until the requirement is met.

    本发明涉及一种转向系统控制策略,用于解决转向系统的稳定性及安全性的问题。具体的,在系统调节过程中首先通过监测车辆行驶速度信号、方向盘转角信号,车轮转角信号、系统各部分压力信号等来判断系统是否正常工作,若正常,再检查电机或发动机取力口转速是否达到了使用要求,若达标,则控制阀组对转向油缸进行充放油,并实时采集车轮转角信号和各位置工作压力信号;若电机或发动机取力口转速未达到使用要求,则启动应急转向系统,利用蓄能器向系统提供补偿压力保证正常工作,进一步判断工作压力及车轮转角是否满足使用要求,若达到目标位置则执行自动对中功能,转向结束,若未达到目标位置则继续通过对转向油缸的充放油进行调节直至满足要求。
