Embodiment Construction

[0047] In order to solve the defects in the prior art that the automatic test system of the body controller has high cost and cannot establish a fault model of the body controller, the main innovations of the present invention are: 1) The industrial computer 100 is externally connected to the interface circuit of the body controller 200 board 400, and simulate and output fault test signals through the industrial computer 100; 2) adopt parallel data transmission mode between the industrial computer 100 and the vehicle body controller 200; The waveform characteristics are compared with the waveform characteristics of a set of pre-stored standard output waveforms to determine whether the vehicle body controller 200 is faulty.

[0048] Since the present invention adopts the design of carrying out fault testing on the vehicle body controller 200 through the external industrial computer 100 and adopting a data parallel transmission scheme between the industrial computer 100 and the v...

Abstract

The invention discloses a vehicle body controller fault test method and a system based on an industrial personal computer. The system comprises an industrial personal computer (100), a vehicle body controller (200) with an interface circuit board (400), a programmable power supply (300) and a data transmission device (103). The industrial personal computer (100) is used for simulating a group of input signals for a fault test on the vehicle body controller (200) when a vehicle body controller fault test instruction is received. The data transmission device (103) is used for inputting the group of input signals to the vehicle body controller (200) via the interface circuit board (400). The data transmission device (103) is also used for receiving a group of output signals outputted by the vehicle body controller (200) via the interface circuit board (400) and inputting the group of output signals to the industrial personal computer (100). The industrial personal computer (100) is also used for acquiring a fault test result for the vehicle body controller (200) through carrying out waveform feature analysis on the group of output signals.

Description

technical field [0001] The present invention relates to the technical field of fault testing of vehicle body controllers, and more specifically relates to a method and system for fault testing of vehicle body controllers based on an industrial computer. Background technique [0002] The various control functions of the car's body controller are not completely realized through hardware circuits. The existing automatic test technology for the body controller has high requirements for hardware, poor reliability and flexibility, low test efficiency, long test process, and failure to establish faults. Model. The use of the automatic test technology of the body controller is not only difficult to meet the needs of users, but also causes a lot of inconvenience to users. At present, the automatic test technology of body controller needs to be improved to meet the needs of users. How to develop a vehicle body controller fault testing method that can reduce hardware requirements, sa...
