Abstract

The invention provides a CAN bus automatic test system, including a motor controller, a hardware-in-the-loop test system, a calibration system and CAN test software. The hardware-in-the-loop test system communicates with the motor controller under test through CAN communication to simulate the For the motor, battery and vehicle controlled by the motor controller, modify the model parameters in the hardware-in-the-loop test system, and compare the corresponding received signal values ​​in the motor controller to test the CAN signal receiving function of the motor controller; the calibration system passes CAN Calibration Observe and calibrate the parameters of the motor controller, modify the calibration value in the motor controller, and compare the corresponding signal value received in the hardware-in-the-loop test system to test the CAN signal sending function of the motor controller; CAN test software Analyze the files in the motor controller and hardware-in-the-loop test system, establish the mapping relationship of each CAN signal from the motor controller to the hardware-in-the-loop test system, generate test cases for each CAN signal, and execute the test cases.

Description

technical field [0001] The invention relates to the technical field of automobile control, in particular to a CAN bus automatic test system. Background technique [0002] The CAN test of the motor controller is realized based on the hardware-in-the-loop test system and the calibration system. Such as figure 1 As shown, the hardware-in-the-loop test system 20 is the LABCAR system provided by ETAS, including LABCAR hardware 22 and LABCAR software 21, and communicates with the motor controller 10 under test through communication CAN, mainly simulating motors, batteries and complete vehicles; calibration system 30 includes INCA software 31 and hardware CAN card 32 (ES581). INCA software and ES581 are respectively the software and hardware CAN card provided by ETAS for calibration. The parameters of the motor controller 10 under test are observed and calibrated by calibration CAN . During the CAN test, the CAN signal receiving function of the motor controller 10 is tested by m...
