The invention provides a vehicle working condition recognition method and device, and the method comprises the steps: obtaining a plurality of feature parameters in a preset calculation period; for each characteristic parameter, determining a working condition corresponding to at least one characteristic parameter interval in which the characteristic parameter falls, and outputting a sub-score of the characteristic parameter under the working condition; for each working condition, according to the sub-scores of all the characteristic parameters under the working condition, the characteristic parameter score of the working condition of the vehicle in the preset calculation period is determined; and according to the characteristic parameter score, determining a target working condition of the vehicle in the preset calculation period and an engine start-stop strategy. According to the application, the target working condition of the vehicle is determined, and the corresponding engine start-stop strategy is determined according to the target working condition of the vehicle, so that the wear and failure rate of the engine are reduced.

    本申请提供了一种车辆工况识别方法和工况识别装置,其中,该方法包括:获取预设计算周期内的多个特征参数;针对每个特征参数,确定该特征参数落入的至少一个特征参数区间对应的工况,并输出该特征参数在所述工况下的子得分;针对每个工况,根据该工况下的所有特征参数的子得分,确定车辆在所述预设计算周期内该工况的特征参数得分;根据所述特征参数得分,确定车辆在所述预设计算周期的目标工况以及发动机启停策略。通过本申请,确定车辆的目标工况,并根据车辆的目标工况确定对应的发动机启停策略,减少发动机的磨损和故障率。
