The invention discloses a vehicle engine starting method and device, a vehicle and a storage medium, and relates to the technical field of vehicles. The method comprises the steps that when a hybrid vehicle runs in a pure electric mode, current running parameters of the hybrid vehicle are obtained; according to the current operation parameters, the speed change condition of the hybrid vehicle within a preset time period after the current moment is determined; and under the condition that it is determined that the speed change condition meets the preset condition, an engine of the hybrid vehicle is started, so that the pure electric mode of the hybrid vehicle is switched to a hybrid mode or an engine mode. According to the technical scheme, when the hybrid vehicle runs in the pure electric mode, speed prediction is conducted according to the current running parameters, the engine of the hybrid vehicle is started in advance before the vehicle speed reaches the first speed threshold value needing to be switched from the pure electric mode to the hybrid mode, the mode switching fluency of the hybrid vehicle is improved, and the running stability of the hybrid vehicle is improved.

    本发明公开了一种车辆的发动机启动方法、装置、车辆和存储介质,涉及车辆技术领域,该方法包括:混动车辆运行于纯电模式时,获取所述混动车辆的当前运行参数;根据所述当前运行参数确定当前时刻之后预设时间段内所述混动车辆的速度变化情况;在确定所述速度变化情况满足预设条件的情况下,启动所述混动车辆的发动机,以将所述混动车辆由所述纯电模式切换至混动模式或者发动机模式。上述技术方案,混动车辆运行于纯电模式时,根据当前运行参数进行速度预测,在车速达到需要从纯电模式切换到混动模式的第一速度阈值之前预先启动混动车辆的发动机,提升混动车辆模式切换的流畅性,提升混动车辆运行的稳定性。
