Abstract

The invention discloses an electronic controller test system and method. The system comprises an upper computer and a to-be-tested electronic controller, wherein the upper computer is connected with the to-be-tested electronic controller through a controller area network CAN bus; the upper computer is used for sending CAN bus data to the to-be-tested electronic controller; the to-be-tested electronic controller is used for classifying and analyzing the CAN bus data to obtain CAN information, generating a driving signal based on a constructed automobile open system architecture according to theCAN information, and executing the driving signal at a set period to obtain corresponding waveform data; and the upper computer is also used for generating a test result according to the waveform data corresponding to the driving signal. According to the technical scheme, the drive control function of the electronic controller is developed based on an automobile open system architecture, the testprocess of the electronic controller is standardized, different types of CAN bus data are analyzed respectively, and the test efficiency is improved.

Description

technical field

[0001] The embodiments of the present invention relate to the technical field of vehicle testing, and in particular to an electronic controller testing system and method. Background technique

[0002] The electronic controller refers to the electronic control unit (Electronic Control Unit, ECU) in the vehicle, also known as the "driving computer". And calculation, based on this form the drive signal to the engine, and then realize the control of torque, ignition, idle speed and other aspects. The electronic controller plays a core control role for the vehicle, and the test of the electronic controller becomes an important part.

[0003] Existing methods or systems for testing vehicle electronic controllers, in order to reduce costs and increase development speed, often use non-standard writing specifications and no operating system monitoring, resulting in occasional software failures during the test process, and it is difficult to determine the source of th...
