The invention provides an engine control method and device of a hybrid electric vehicle, electronic equipment, a vehicle and a medium. The method comprises the steps of obtaining a power data set and current environment data of a vehicle; the expected target power of an engine in the vehicle is determined according to the power data set, an economic curve corresponding to the current environment data is obtained based on the pre-calibrated corresponding relation between the environment data and the economic curve, the economic curve serves as a target economic curve, and the target economic curve records the corresponding relation between the power of the engine and the rotating speed of the engine; from the target economic curve, the rotating speed of the engine corresponding to the expected target power is determined to serve as the target rotating speed of the engine of the vehicle; and controlling engine operation of the vehicle based on the target rotating speed and the expected target power. Therefore, in different environments, the appropriate economic curve can be automatically selected, so that the engine can be in better economic performance, and energy waste can be reduced.
本申请提供一种混动车的发动机控制方法、装置、电子设备、车辆及介质。方法包括:获取车辆的功率数据集和当前环境数据;根据功率数据集,确定车辆中发动机的期望目标功率,以及基于预先标定的环境数据与经济曲线的对应关系,获取与当前环境数据对应的经济曲线,以作为目标经济曲线,其中,目标经济曲线记录有发动机的功率与发动机的转速的对应关系;从目标经济曲线中,确定与期望目标功率对应的发动机的转速,以作为车辆的发动机的目标转速;基于目标转速、期望目标功率,控制车辆的发动机运行。如此,在不同环境下,可以自动选择合适的经济曲线,从而使得发动机能处于较优的经济性能,有利于减少能源浪费。
