Abstract

The invention belongs to the technical field of XCP calibration, and particularly relates to an XCP calibration test method based on a TC397 development board. On the basis of a TC397 development board, an ECU program runs in the development board, an ECU is connected by using a CANApe, XCP calibration test is carried out through CAN communication, and the problem that many parameters in an algorithm are adjusted in good time according to different driving intentions and working conditions is solved. The method comprises the following steps that: an ECU program is injected into a TC397 development board and run; ASAP2Studio software uses a map file to automatically generate an a2l file; a CANApe project is created, XCP protocol configuration is selected, and CAN channel configuration is carried out; the TC397 development board is connected with CANApe software through a CAN (Controller Area Network) line; CANApe software is used for being connected with an ECU program in an authentication mode, and normal communication is achieved; an a2l file observed quantity and a calibrated quantity are set; a CANApe software interface receives the observed quantity and the observed quantity changes; and the CANApe software interface modifies the calibration value and checks the change of the calibration value.

Description

technical field [0001] The invention belongs to the technical field of XCP calibration, in particular to an XCP calibration test method based on a TC397 development board. Background technique [0002] In today's automotive systems, the electronic control unit (ECU) is the central system in the automotive system. The programs in the ECU are designed by software engineers, and the software engineers do not have the ability to set these parameters to reasonable values. The experiment is set according to the automobile mathematical model. This part of the work is finally determined by the application engineer / calibration engineer after the software development is completed by changing the parameter analysis performance iteratively and iteratively. Therefore, the application / calibration engineer needs to be able to measure the ECU during the running of the ECU program. Parameters, means of calibrating ECU parameters. The XCP communication protocol provides such a means and poss...
