The invention relates to the technical field of electric vehicle control, in particular to an electric vehicle speed diagnosis method and device, a medium and a vehicle control unit. The method specifically comprises the following steps: acquiring speed information of a plurality of electric vehicles including currently used speed information; calculating vehicle speed information of a plurality of motor signal sources; fusing the vehicle speed information of the motor signal sources and the vehicle speed information of the electric vehicles to judge whether the currently used vehicle speed information fails or not. By properly processing and fusing the multi-path source vehicle speed information, whether the currently used vehicle speed information is reasonable or not can be diagnosed, and the accuracy of the current vehicle speed can be fed back in time, so that the vehicle control precision is improved, and drivability optimization, emission optimization and energy consumption control optimization are facilitated.
本发明涉及电动车控制技术领域,特别涉及一种电动车车速诊断方法、装置、介质及整车控制器。具体方法为:获取其中包括当前使用车速信息的若干电动车车速信息;测算若干电机信号源车速信息;融合若干电机信号源车速信息以及若干电动车车速信息,判断当前使用车速信息是否故障。本发明通过对多路来源车速信息的适当处理融合,可诊断当前使用车速信息是否合理,及时反馈当前车速的准确性,从而提高车辆控制精度,有利于驾驶性能优化、排放优化以及能耗控制优化。
