Fault detection system and method, automobile domain controller, storage medium and vehicle

The invention provides a fault detection system and method, an automobile domain controller, a storage medium and a vehicle. The fault detection system comprises at least one integrated circuit and a software detection module, the software detection module is connected with the at least one integrated circuit, and the software detection module is used for detecting a fault detection result of the at least one integrated circuit. According to the scheme, when the voltage fault of the integrated circuit is detected, the fault detection result of the integrated circuit is determined again through software, and the accuracy of fault detection of the integrated circuit is improved under the condition that hardware distribution is not changed.
