The invention discloses a high-stability electric vehicle steering control method and control system, and relates to the technical field of electric vehicle steering control, and the method comprises the steps: collecting part of state data of a vehicle in a driving steering state, and generating a stability coefficient for evaluating the steering of the vehicle; adjusting the suspension rigidity of the vehicle suspension system, if the adjustment effect is smaller than the expectation, continuing to adjust the vehicle driving steering state, generating a controllability coefficient according to the response speed and the gravity center change of the vehicle, and establishing a trained vehicle driving model to predict the steering state of the vehicle; the method comprises the following steps: predicting the running condition of a vehicle, establishing a prediction data set according to a prediction result so as to generate a risk coefficient, adjusting the running condition of the vehicle through simulation analysis, outputting an adjusted running scheme, and after the running scheme is executed by the vehicle, if an expectation is not reached, sending a deceleration instruction. And the controllability of the vehicle is evaluated, so that the vehicle can be conveniently adjusted and improved, and the driving safety of the vehicle is guaranteed.

    本发明公开了一种稳定性高的电动车转向控制方法及控制系统,涉及电动车转向控制技术领域,采集行驶转向状态下的车辆的部分状态数据,生成对车辆转向的进行评价的稳定性系数;对车辆悬挂系统的悬挂刚度进行调整,若调整效果小于预期,继续对车辆行驶转向状态进行调整,依据车辆的响应速度及重心变化生成操控性系数,建立训练后的车辆行驶模型,以其对车辆的转向状态进行预测,并依据预测结果建立预测数据集进而生成风险系数,通过仿真分析对车辆的行驶条件进行调整,输出调整后的行驶方案,在由车辆执行该行驶方案后,若未达到预期,则发出减速指令。通过对车辆的操控性进行评估也便于对其进行调整和改善,对车辆行驶的安全性形成保障。
