Embodiment Construction

[0041] The core of the present invention is to provide a test method and system for the CAN signal of the controller, directly generate the dbc file of the CAN protocol into a script file that can be used by the debugging tool, and after importing the test tool, the transmission of the CAN data can be simulated to improve the test efficiency , to ensure the correctness of CAN communication data transmission.

[0042] In order to make the purpose, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments It is a part of embodiments of the present invention, but not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without making creati...

Abstract

The invention discloses a controller CAN signal test method. The controller CAN signal test method comprises the following steps: using a CAN protocol dbc file to generate a cmm script file through a Perl script file; importing the cmm script file in a simulation test tool, and sending simulated CAN data according to the cmm script file; receiving simulated CAN data sent by a controller to be tested through a network analysis test tool; and judging whether the received simulated CAN data is consistent with the sent simulated CAN data or not by means of the CAN protocol dbc file. By means of the controller CAN signal test method, the CAN protocol dbc file can be directly used for generating the script file which can be used by a Lauterbach debugging tool, the script file is imported to the testing tool directly to simulate the sending of the CAN data, therefore, the test efficiency is improved, and the sending correctness of CAN communication data is ensured. The invention discloses a controller CAN signal test system and a computer with the beneficial effects.

Description

technical field [0001] The invention relates to the technical field of vehicle engineering, in particular to a method and system for testing CAN signals of a controller. Background technique [0002] The controller is the communication and control center of the vehicle, which plays a decision-making role in the running state of the vehicle, and is one of the core components in the vehicle. The interaction between various controllers needs to pass through the CAN bus. Therefore, there are hundreds of CAN signals for data transmission, and each signal is an important signal for controlling the safe operation of the vehicle. When a certain signal is received or sent for processing Any error will cause a great safety hazard to the vehicle. [0003] The current test of the CAN signal of the controller is through the tester to add the signal one by one in the debugging tool, and to send and receive the simulated data. Due to the large number of CAN signals, it takes a lot of tim...
