    • A vehicle is disclosed that has multiple coolant paths selected by control of a three-way valve in which the position of the valve is detectable. A method for detecting the valve position during fault conditions is disclosed. The vehicle has a heating system that includes a first coolant loop with a heating source, a water pump, and a heater core. The heating system also has a second coolant loop that includes an engine and a second water pump, in addition to the elements of the first coolant loop. Temperature sensors are located in each coolant loop. A three-way valve fault is detected by monitoring the behavior of the temperature sensors in response to the position of the three-way valve and the status of the heating sources.
    • 公开了一种车辆,其具有通过三通阀的控制选择的多个冷却剂路径,其中阀的位置可检测。 公开了一种在故障条件下检测阀门位置的方法。 车辆具有加热系统,其包括具有加热源的第一冷却剂回路,水泵和加热器芯。 除了第一冷却剂回路的元件之外,加热系统还具有包括发动机和第二水泵的第二冷却剂回路。 温度传感器位于每个冷却剂回路中。 通过监测温度传感器响应三通阀的位置和加热源的状态来检测三通阀故障。
