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...

Abstract

The invention discloses a real-vehicle testing automatic platform and method for a diagnosis function of a control system. The real-vehicle testing automatic platform comprises an upper computer, rapid prototype equipment, a fault injection box and a CANAlyzer. The rapid prototype equipment is connected with the upper computer and obtains an electronic control unit interface model and electronic control unit logic fault automatic testing programs of a to-be-tested electronic control unit from the upper computer. The fault injection box is used for being connected between a male connector and afemale connector of a low-voltage connector assembly of the to-be-tested electronic control unit in series. The rapid prototype equipment is used for being connected to a sensor input signal interface and a CAN signal interface of the fault injection box in series and connected to a sensor output signal interface. The CANAlyzer operates on the upper computer. According to the real-vehicle testingautomatic platform and method for the diagnosis function of the control system, the problems that when the diagnosis function of a new energy vehicle is tested, the testing environment is not preciseenough, the function related to the dynamic working condition of the vehicle and the failure mode cannot be tested can be solved.

Description

technical field [0001] The invention belongs to the technical field of real-vehicle testing of diagnostic functions of new energy vehicles, and in particular relates to an automated platform and a testing method for real-vehicle testing of diagnostic functions of a control system. Background technique [0002] With the rapid development of new energy vehicle technology, the safety goals of motor vehicle systems are gradually increasing. Automotive electronic control units (Electronic Control Unit, referred to as ECU) generally have fault self-diagnosis and protection functions. When the system fails, it can display the fault information on the dashboard at the first time to remind users to find the problem in time, and automatically record the fault at the same time. code and apply a diagnostic protective action to the vehicle. The current diagnostic function test is mainly for single ECU, and the test methods mainly include HIL simulation test, yellow board test, etc., and...
