Description

technical field

[0001] The invention belongs to the technical field of ECU short-circuit protection test devices, and in particular relates to an ECU short-circuit protection performance test platform. Meanwhile, the invention also provides an ECU short-circuit protection performance test method. Background technique

[0002] ECU short-circuit protection performance refers to the degree of abnormality in the functional state of the signal line and load circuit of the ECU when it is short-circuited to the power supply and to the ground when an abnormal situation occurs. If the functional state is not affected at all, it is considered that the ECU’s The performance of the item is the best, and the abnormal short-circuit working condition of the ECU has the following two characteristics in actual work: the probability of the short-circuit working condition is small, and it is difficult to find defects in this aspect during product development; once the short-circuit abnormal wor...
