The invention relates to a vehicle speed threshold determination method, device and equipment and a storage medium, and relates to the technical field of whole-vehicle electric control of pure electric vehicles. The method comprises the steps that the target voltage of a target vehicle, the safety voltage of the target vehicle, the magnetic flux of the target vehicle, the number of pole pairs of a motor of the target vehicle, the wheel radius of the target vehicle and the motor speed ratio of the target vehicle are obtained, and the target voltage of the target vehicle is used for representing the voltage withstanding value of the target vehicle; based on the target voltage of the target vehicle, the safety voltage of the target vehicle, the magnetic flux of the target vehicle, the number of pole pairs of a motor of the target vehicle, the wheel radius of the target vehicle and the motor speed ratio of the target vehicle, a first vehicle speed threshold value and a second vehicle speed threshold value are determined; and determining the smaller vehicle speed threshold value in the first vehicle speed threshold value and the second vehicle speed threshold value as a target vehicle speed threshold value. Therefore, the technical problem that the vehicle triggers traction protection inaccurately can be solved.

    本申请涉及一种车速阈值确定方法、装置、设备及存储介质,涉及纯电动汽车整车电控技术领域。该方法包括:获取目标车辆的目标电压、该目标车辆的安全电压、该目标车辆的磁通量、该目标车辆的电机极对数、该目标车辆的车轮半径以及该目标车辆的电机速比,该目标车辆的目标电压用于表征该目标车辆的耐压值;基于该目标车辆的目标电压、该目标车辆的安全电压、该目标车辆的磁通量、该目标车辆的电机极对数、该目标车辆的车轮半径以及该目标车辆的电机速比,确定第一车速阈值以及第二车速阈值;将该第一车速阈值与该第二车速阈值中较小的车速阈值确定为目标车速阈值。由此,可以解决车辆触发牵引保护的不准确的技术问题。
