The application provides a performance interference test method and
system for a vehicle electrical component. A console can generate an interference
signal in response to a start test instruction. Each interference line processes the interference
signal and injects the processed interference
signal into a first vehicle electrical component. Since the interference lines include multiple interference lines for
processing the interference signal in different types, the first vehicle electrical component can be interfered by multiple interference signals processed in different types at the same time, and there is a
coupling effect between the multiple interference signals. Thus, the
scenario in which the first vehicle electrical component is interfered when the actual vehicle is driving is truly restored, and the reliability is high. Furthermore, the console receives first communication data of the first vehicle electrical component when working, which is collected by a data collection module, and determines whether the working state of the first vehicle electrical component is abnormal based on the first communication data, and outputs a first test result.
