Embodiment Construction
[0024] The present invention will be further described below in conjunction with accompanying drawing.
[0025] Such as figure 1 The real vehicle test automation platform for control system diagnosis function shown includes upper computer 7, rapid prototyping equipment 3, fault injection box 2 and CANAlyzer.
[0026] The upper computer 7 is configured with an electronic control unit interface model and an electronic control unit logic fault automated test program; specifically: use Matlab / Simulink software on the upper computer 7 to model the electronic control unit interface model, and simultaneously for the electronic control unit Control logic failures of control units Develop automated test procedures for electronic control unit logic failures. Through the electronic control unit interface model, the CAN signal and sensor signal to the electronic control unit to be tested can be modified online according to the test requirements.
[0027] The rapid prototyping device 3 i...
