The invention discloses an engine starting method and device, a vehicle, electronic equipment and a storage medium, and relates to the technical field of vehicles, in a target mode, a preset target rotating speed and a target torque limiting range are obtained, and the target torque limiting range is used for calibrating the torque output range of a target motor in the target engine starting stage, the value range of the minimum torque limit in the target torque limit range is greater than or equal to 0Nm; driving the target engine to ignite according to the preset target rotating speed; and after the target engine is ignited, if the actual rotating speed of the target motor is not equal to the preset target rotating speed, the output torque of the target motor is adjusted within the target torque limiting range till the starting stage of the target engine is ended. Compared with the prior art, the output torque of the target motor is limited to be the positive torque all the time, the torque output by the target motor is prevented from generating large positive and negative alternation, and then the problem that the whole vehicle shakes and impacts due to the positive and negative alternation of the torque output by the target motor is solved.

    本发明公开了发动机的启动方法、装置、车辆、电子设备和存储介质,涉及车辆技术领域,在目标模式下,获取预设目标转速及目标扭矩限制范围,目标扭矩限制范围用于在目标发动机启动阶段标定目标电机的扭矩输出范围,其中,目标扭矩限制范围中最小扭矩限制的取值范围为大于或等于0Nm;根据预设目标转速驱动目标发动机点火;在目标发动机点火之后,若目标电机的实际转速不等于预设目标转速,则在目标扭矩限制范围内对目标电机的输出扭矩进行调节,直至目标发动机启动阶段结束。与相关技术相比,限制目标电机的输出扭矩一直为正扭矩,防止了目标电机输出的扭矩会产生较大的正负交变,进而解决了目标电机输出的扭矩正负交变而造成的整车抖动冲击问题。
