The invention discloses a vehicle speed control method for a working condition method energy consumption test. According to the invention, the assistance value and the assistance adjustment amount canbe calculated. Even if the actual vehicle speed is deviated from the current target vehicle speed due to deviation in calculation of the assistance value, the actual vehicle speed can be adjusted tothe current target vehicle speed. The reason is that a preset closed-loop control algorithm is adopted to calculate the assistance adjustment amount, then the vehicle speed can be controlled accordingto the assistance value and the sum of the assistance adjustment amount, and fine adjustment of the assistance value is realized. The speed control is relatively accurate, and the precision of an energy consumption test result is improved. The invention further discloses a vehicle speed control device and equipment for the working condition method energy consumption test. The vehicle speed control device and equipment have the same beneficial effects as the vehicle speed control method for the working condition method energy consumption test.

    本发明公开了一种工况法能耗测试的车速控制方法,本申请可以计算出助力值以及助力调整量,即使助力值计算的有偏差,导致实际车速与当前目标车速出现偏差,但是由于本申请采用预设闭环控制算法计算出了助力调整量,然后能够根据助力值以及助力调整量之和对车速进行控制,实现了对助力值的微调,从而能够将实际车速调整为当前目标车速,速度控制较为精确,提高了能耗测试结果的精度。本发明还公开了一种工况法能耗测试的车速控制装置及设备,具有如上工况法能耗测试的车速控制方法相同的有益效果。
