The invention discloses a vehicle idle speed control method and device and a hybrid power vehicle. The method comprises the steps that based on vehicle control information of a target vehicle, it is determined that the target vehicle enters an idle speed control state; in the idle speed control state, in response to the fact that the current battery capacity of the target vehicle is higher than a first threshold value, motor rotating speed control is conducted on the target vehicle according to a first control instruction, and in response to the fact that the current battery capacity is lower than a second threshold value, motor rotating speed control and engine torque control are conducted on the target vehicle according to a second control instruction; wherein the first control instruction is determined by a first target idle speed corresponding to the target vehicle in an electric driving state, and the second control instruction is determined by a second target idle speed corresponding to the target vehicle in a hybrid driving state and a target idle torque. The technical problems that a vehicle idle speed control method provided by the related technology is low in accuracy and poor in whole vehicle comfort are solved.

    本发明公开了一种车辆怠速控制的方法、装置及混合动力车辆。其中,该方法包括:基于目标车辆的车辆控制信息,确定目标车辆进入怠速控制状态;在怠速控制状态下,响应于目标车辆的当前电池容量高于第一阈值,按照第一控制指令对目标车辆进行电机转速控制,以及响应于当前电池容量低于第二阈值,按照第二控制指令对目标车辆进行电机转速控制和发动机扭矩控制;其中,第一控制指令由目标车辆在电动驱动状态下对应的第一目标怠速转速确定,第二控制指令由目标车辆在混动驱动状态下对应的第二目标怠速转速和目标怠速扭矩确定。本发明解决了相关技术提供的车辆怠速控制方法其精确度低、整车舒适性差的技术问题。
