The invention discloses a control method for turning on the air conditioner of a hybrid vehicle in a parked state, comprising: when the hybrid vehicle is in a parked state and a request signal for turning on the air conditioner is received, acquiring the state of charge SOC of a power battery; If the SOC is greater than the preset value, after the air conditioner is started and before the air conditioner clutch is engaged, the ISG motor integrated with starter and power generation is controlled to work according to the first power compensation value; wherein, the first power compensation value is a positive value, The value range of the preset value is above 60%. The above solution loads an additional positive power compensation to the ISG motor when the SOC value of the power battery is high, which improves the service life of the power battery while solving the abnormal noise of the gearbox.
Description
technical field [0001] The present application relates to the technical field of new energy vehicle control, in particular to a hybrid vehicle and its control method and control device for turning on the air conditioner in the parking state. Background technique [0002] For hybrid vehicles, when the air conditioner is turned on in the parking state, there are often obvious NVH (Noise, Vibration, Harshness) abnormal noise problems. The abnormal noise usually appears a few seconds after the air conditioner clutch is engaged, and it will last for several seconds. On the one hand, the abnormal noise reflects the abnormality of the vehicle's internal equipment in this state, and on the other hand, it also reduces the driving experience. Contents of the invention [0003] The invention provides a hybrid vehicle and its control method and control device for turning on an air conditioner in a parking state, so as to solve or partially solve the technical problem of vehicle abnorm...
