The invention discloses an expected steering curve determination method for vehicle synchronous steering. The method comprises the steps of determining the maximum steering efficiency and the minimumsteering efficiency of the steering efficiency of a full-hydraulic steering synchronous system; drawing steering curves corresponding to the maximum steering efficiency and the minimum steering efficiency respectively; with the steering curve corresponding to the maximum steering efficiency serving as an upper boundary, and the steering curve corresponding to the minimum steering efficiency serving as a lower boundary, forming a feasible region of the expected steering curve, wherein other regions are infeasible regions, and any steering curve in the feasible region can serve as the expected steering curve. Accurate synchronous steering of a vehicle is achieved, the consistency of the rotating angle of a steering wheel and the rotating angle of the steering wheel is guaranteed, and the steering safety and the working accuracy are improved.

    本发明公开了一种车辆同步转向的期望转向曲线确定方法,包括:确定全液压转向同步系统的转向效率的最大转向效率和最小转向效率;分别绘制出所述最大转向效率和所述最小转向效率对应的转向曲线;以所述最大转向效率所对应的所述转向曲线为上边界,所述最小转向效率所对应的所述转向曲线为下边界,构成所述期望转向曲线的可行域,其余区域为不可行域,其中所述可行域内的任意转向曲线均可作为所述期望转向曲线。本发明实现了车辆精准的同步转向,保证了方向盘与转向轮转角的一致性,提高了转向安全性与工作的精确性。
