The invention provides a method for controlling start and stop of an engine through external discharge of an automobile and the hybrid automobile, and belongs to the technical field of automobile control. The method comprises the following steps: after receiving an external discharge instruction, detecting whether an automobile meets an external discharge engine starting condition or not in response to the external discharge instruction; and when it is detected that the automobile meets the external discharge engine starting condition, the engine is controlled to be started. Therefore, when the power battery cannot meet the requirement of internal high and low voltage loads for continuous external discharge, the engine is controlled to start in time to drive the generator to supply power to the automobile, and continuous external discharge can be ensured. And after the engine is started, when it is detected that the automobile meets the external discharge engine stopping condition, the engine is controlled to stop. Therefore, when the power battery is enough to meet the internal high-low voltage load requirement and can guarantee continuous external discharge for a certain time, the engine is controlled to stop in time so as to stop the generator from continuously supplying power to the automobile, and energy waste can be avoided.

    本申请提出一种汽车对外放电控制发动机启停的方法和混动汽车,属于汽车控制技术领域。该方法在接收到对外放电指令后,响应于对外放电指令,先检测汽车是否满足对外放电启动发动机条件。当检测到汽车满足对外放电启动发动机条件,则控制发动机启动。即可在动力电池无法满足内部高低压负载同时持续对外放电时,及时控制发动机启动来驱动发电机给汽车供电,能够保证持续对外放电。在发动机启动之后,当检测到汽车满足对外放电停止发动机条件,则控制发动机停机。即可在动力电池足够满足内部高低压负载需求且能保证一定时间的持续对外放电时,及时控制发动机停机,以停止发电机继续给汽车供电,能够避免能源浪费。
