The disclosure provides an electrified vehicle thermal management system. A vehicle thermal management system including a refrigerant circuit, a coolant circuit, a chiller, and a controller is provided. The refrigerant circuit may include an electric air conditioning (eAC) compressor and a pressure sensor. The coolant circuit may include a high-voltage battery. The chiller selectively thermally links the circuits. The controller may be programmed to, responsive to receipt of a sensor signal indicating refrigerant pressure exiting the eAC compressor is greater than a high threshold, output a pressure sensor fault error indicating the pressure sensor is faulty. The system may further include a timer to monitor operational timing of the eAC compressor. The controller may be further programmedto direct the system to operate without monitoring the eAC compressor responsive to the timer indicating the eAC compressor has been off for a time-period less than a time threshold reflective of theeAC compressor not being in an at rest state.

    本公开提供了“电动化车辆热管理系统”。提供了一种车辆热管理系统,其包括制冷剂回路、冷却剂回路、冷却器以及控制器。所述制冷剂回路可以包括电动空调(eAC)压缩机和压力传感器。所述冷却剂回路可以包括高压电池。所述冷却器将所述回路选择性地热连接。所述控制器可以被编程为响应于接收到指示排出所述eAC压缩机的制冷剂压力大于高阈值的传感器信号而输出指示所述压力传感器有故障的压力传感器故障错误。所述系统还可以包括计时器以监测所述eAC压缩机的操作定时。所述控制器还可以被编程为响应于所述计时器指示所述eAC压缩机已经关闭的时间段小于反映所述eAC压缩机未处于静止状态的时间阈值而指示所述系统在不监测所述eAC压缩机的情况下操作。
