The invention provides a pedestrian speed control method and system for a pedestrian test. The method comprises the steps that the speed of a vehicle, the longitudinal distance from a collision point and the obtaining time are obtained; calculating the longitudinal distance between the vehicle and the pedestrian, calculating the time when the vehicle arrives at the collision point according to the distance and the speed, and judging whether the time is the same as the time when the pedestrian arrives at the collision point; if the time for reaching the collision point is the same, starting to drive the pedestrian to transversely move to the collision point; in the whole transverse movement process of the pedestrian, the time for the vehicle to reach the collision point is calculated according to the change of the speed of the vehicle, and then the speed of the pedestrian is adjusted, so that the time error of the pedestrian and the vehicle reaching the collision point is within a preset range. According to the speed of the vehicle, the speed of the pedestrian in the constant-speed driving stage can be calculated, real-time adjustment is carried out according to requirements, the test requirements are met, and the accuracy of test data is improved.

    本发明提供一种用于行人试验的行人速度控制方法及系统,获取车辆的速度、距离碰撞点的纵向距离以及获取时间;对车辆离行人纵向的距离进行计算,根据距离和速度计算车辆到达碰撞点的时间,判断是否与行人到达碰撞点的时间相同;如果达到碰撞点时间相同,则开始驱动行人横向移动,驶向碰撞点;行人在整个横向移动过程中,根据车辆的速度的变化,计算车辆到达碰撞点的时间,进而调整行人的速度,使行人和车辆到达碰撞点的时间误差在预设范围内。本发明可以根据车辆的速度,对行人匀速行驶阶段的速度进行计算,并根据要求进行实时调节,满足试验要求,提高试验数据的准确性。
