Real vehicle test automation platform and test method for control system diagnosis function

Abstract

The invention discloses a control system diagnosis function real vehicle test automation platform and a test method, including a host computer, rapid prototyping equipment, fault injection box and CANAlyzer; the rapid prototyping equipment is connected with the host computer, and the rapid prototyping equipment is connected The electronic control unit interface model of the electronic control unit to be tested and the automatic test program for the logic fault of the electronic control unit are obtained in the machine; ; The rapid prototyping device is used to be connected in series to the sensor input signal interface and the CAN signal interface of the fault injection box, and connected to the sensor output signal interface; the CANalyzer runs on the host computer. The invention can solve the problem that the test environment is not accurate enough during the diagnostic function test of the new energy vehicle, and the functions and failure modes related to the dynamic working conditions of the vehicle cannot be tested.

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...
