The invention belongs to the technical field of automobile driving, and discloses an engine control method, device and equipment and a storage medium. The method comprises the steps that current vehicle parameters are obtained, wherein the current vehicle parameters comprise at least one of the current vehicle speed, the current vehicle demand torque and the current battery pack electric quantity; when the current vehicle parameters meet preset conditions, whether an engine is in a cold state or not is judged; when the engine is in the cold state, the engine is controlled to conduct cold start; according to the method, the engine is started according to the judgment result through multiple judgments of the current vehicle parameters, so that the problems that the electric quantity of a battery pack is too low or the required torque is too large when the engine is started due to the fact that the battery pack of a non-plug-in hybrid power vehicle is small, and the engine frequently skips cold start are solved, skipping of cold start of the engine is effectively reduced, and the engine starting efficiency is improved. And the effect of reducing the pollutant emission of the engine is achieved.

    本发明属于汽车驾驶技术领域,公开了一种发动机控制方法、装置、设备及存储介质;该方法包括:获取当前车辆参数,所述当前车辆参数包括当前车速、当前车辆需求扭矩以及当前电池包电量中的至少一种;在所述当前车辆参数符合预设条件时,判断发动机是否处于冷态;在所述发动机处于冷态时,控制所述发动机进行冷启动;本发明通过当前车辆参数的多重判断,再根据判断结果启动发动机,解决了因为非插电式混动车型的电池包较小,导致启动发动机时电池包电量太低或是需求扭矩太大,发动机频繁跳过冷启动的问题,有效减少了发动机冷启动的跳过,达到了降低发动机污染物排放量的效果。
