The invention relates to an air conditioner control method and system during engine aftertreatment regeneration, and belongs to the technical field of whole vehicle engine control. According to the scheme, in the running process of the air conditioner, the air conditioner controller can detect the starting and stopping conditions of the DPF according to the preset time interval, and when it is detected that the DPF is started, running of the air conditioner is controlled by detecting the ambient temperature outside the vehicle and the running speed of the vehicle. According to the scheme, the problems that in the prior art, when the DPF is regenerated, the air conditioner is started, the vehicle is in the parking state, the air temperature in the environment outside the vehicle is high, the pressure value of the air conditioner exceeds the safety range, and finally the air conditioner breaks down are solved.
本发明涉及一种在发动机后处理再生时的空调控制方法及系统,属于整车发动机控制技术领域。本发明方案包括空调运行的过程中,空调控制器会按照预先设定的时间间隔检测DPF的启停情况,当检测到DPF启动时,通过检测车外环境温度和车辆的行驶速度来控制空调的运行。本发明方案用以解决现有技术中DPF再生时空调开启且车辆处于驻车状态,由于车外环境中空气温度较高,则会导致空调压力值超出安全范围运行,最终导致空调故障的问题。
