The invention relates to the field of automobile thermal management, in particular to control logic based on a vehicle-mounted refrigerator. Comprising a KL30 power supply wire harness, a power switch, a vehicle-mounted refrigerator evaporator outlet temperature and pressure sensor, a vehicle-mounted refrigerator storage chamber temperature sensor, a vehicle-mounted refrigerator coolant temperature sensor, a vehicle-mounted refrigerator controller, an LIN wire harness, a CANoe upper computer, a CAN/LIN bus, a whole vehicle heat management controller, a compressor, an electronic expansion valve and an axial flow fan. A vehicle-mounted refrigerator controller is connected with a whole vehicle heat management controller through a CANoe upper computer, an LIN wire harness and a CAN/LIN bus, signal interaction is achieved, parameters such as temperature and pressure are read through a sensor to be detected and calculated in real time, whether a vehicle-mounted refrigerator is in a normal state or not and whether the situation that the vehicle-mounted refrigerator deviates from a set value or not are further judged, and the vehicle-mounted refrigerator is in a normal state or not is judged. And the deviation value is adjusted in real time, so that the refrigerating and heating efficiency of the vehicle-mounted refrigerator can be quickly and effectively improved. Through the control logic, a new thought is provided for optimization of the vehicle-mounted refrigerator.
本发明涉及汽车热管理领域,具体涉及基于车载冰箱的控制逻辑,包括KL30供电线束、电源开关、车载冰箱蒸发器出口温压传感器、车载冰箱储藏室温度传感器、车载冰箱蓄冷剂温度传感器、车载冰箱控制器、LIN线束、CANoe上位机、CAN/LIN总线、整车热管理控制器、压缩机、电子膨胀阀及轴流风扇。运用CANoe上位机、LIN线束与CAN/LIN总线使车载冰箱控制器与整车热管理控制器连接,实现信号交互,并通过传感器对温度、压力等参数的读取进行实时的检测与计算,进一步判断车载冰箱是否处于正常状态,以及是否有偏离设定值的情况出现,并对偏离值进行实时的调节,可快速有效地提升车载冰箱的制冷、制热效率。通过本发明的控制逻辑,为车载冰箱的优化提供了一种新的思路。
