The invention discloses a steering-by-wire automobile front wheel steering load acquisition method and system, and the method comprises the steps: detecting the current speed of an automobile in real time in the driving process of the automobile, and determining the interval lower reference speed and the interval upper reference speed of an automobile speed interval where the current speed is located; according to the front wheel steering load under the fixed vehicle speed, the front wheel reference load under the interval lower reference vehicle speed and the interval upper reference vehicle speed is determined; and determining the front wheel steering load at the current vehicle speed according to the front wheel reference load at the interval lower reference vehicle speed and the interval upper reference vehicle speed. By dividing the vehicle speed interval and combining the interpolation method to obtain the front wheel instantaneous load when the speed changes continuously, the accuracy, adaptability and efficiency of obtaining the front wheel steering load torque are improved.

    本发明公开了一种线控转向汽车前轮转向负载获取方法及系统,车辆行驶过程中,实时检测车辆当前车速,确定当前车速所在车速区间的区间下届基准车速和区间上届基准车速;根据固定车速下的前轮转向负载确定所述区间下届基准车速和区间上届基准车速下的前轮基准负载;根据区间下届基准车速和区间上届基准车速下的前轮基准负载确定当前车速下的前轮转向负载。本发明通过划分车速区间,结合插值法获取速度不断变化时的前轮瞬时负载,提高了前轮转向负载力矩获取的准确性、适应性和高效性。
