The invention provides a power domain controller and a vehicle, and relates to the technical field of vehicles. The power domain controller comprises a hardware active short-circuit protection loop, a bus voltage overvoltage detection loop and a three-phase current overcurrent detection loop, the bus voltage overvoltage detection loop and the three-phase current overcurrent detection loop are connected with the hardware active short-circuit protection loop, the bus voltage overvoltage detection loop is used for detecting whether bus voltage in a motor driving system is larger than a hardware overvoltage protection threshold value or not, and the three-phase current overcurrent detection loop is connected with the hardware active short-circuit protection loop. When it is detected that the bus voltage is larger than a hardware overvoltage protection threshold value, a hardware active short circuit protection loop is triggered to control active short circuit of an IGBT in the motor driving system; the three-phase current overcurrent detection loop is used for detecting whether the three-phase current in the motor driving system is greater than a hardware overcurrent protection current threshold value or not, and triggering the hardware active short circuit protection loop to control the IGBT active short circuit in the motor driving system when detecting that the three-phase current is greater than the hardware overcurrent protection current threshold value. And the reliability and the safety of the power domain controller are improved.
