The invention provides a control method, a control device and equipment for a vehicle hybrid power system, and relates to the technical field of vehicle control. The method comprises the steps that according to the electric quantity difference value of the current battery electric quantity and the target battery electric quantity of a vehicle battery power system, a current whole vehicle demand power calibration value is inquired and obtained, and according to the current whole vehicle demand power calibration value and a preset power hysteresis threshold value, boundary power for starting an engine power system is obtained; when it is determined that the actual value of the whole vehicle demand power is smaller than the current whole vehicle demand power calibration value, if the actual value of the whole vehicle demand power is larger than or equal to the boundary power for starting the engine power system, a corresponding operation request is sent to the engine power system according to the previous operation state of the engine power system. According to the method, the electric quantity difference value of the vehicle battery power system is associated with the starting of the engine, so that the flexible response to the low-power requirement of the vehicle is ensured, and the problems of unstable power output and poor driving experience caused by frequent starting and stopping are solved.

    本申请提供一种车辆混合动力系统的控制方法、控制装置及设备,涉及车辆控制技术领域。该方法包括:根据车辆电池动力系统的当前电池电量和目标电池电量的电量差值,查询获取当前整车需求功率标定值,并根据当前整车需求功率标定值和预设功率滞回阈值,获取启动发动机动力系统的边界功率;在确定整车需求功率实际值小于当前整车需求功率标定值时,若整车需求功率实际值大于或等于启动发动机动力系统的边界功率,则根据发动机动力系统的前次运行状态,向发动机动力系统发送相应的运行请求。本申请通过对车辆电池动力系统的电量差值与发动机启动的进行关联,确保了对车辆低功率需求的灵活响应,解决频繁启停造成的动力输出不平稳,驾驶体验差的问题。
