Based on a car load automated diagnostic tester system of CANoe, mainly comprise diagnostic command sending module, diagnostic message read module, diagnostic message processing module and diagnostic message display module.
Diagnostic command sending module mainly carries out transmission diagnostic command by the Panel interface creating CANoe, in this function, can according to testing requirement, to needing the target ECU of test and needing the diagnostic command of test to select, after operation, CANoe will carry out automatic test to corresponding ECU.Meanwhile, also whole diagnostic command transmission can be carried out successively for ECU.
Diagnostic message read module mainly receives the diagnosis message that ECU returns, and its effect is that the diagnostic message returned by ECU is sent to diagnostic message processing module and processes.
The diagnostic message that diagnostic message processing module mainly diagnoses ECU to return is carried out Treatment Analysis and stores.The kind of the diagnostic message message that diagnostic message processing module returns according to ECU, carries out analyzing and processing.
Diagnostic message display module mainly shows the information of diagnostic command sending module, diagnostic message read module and diagnostic message processing module, and shows in the Panel interface of CANoe and the CAN message display interface of CANoe and resolve diagnosis message.
Be be connected with car load CAN network by CAN transceiver based on CANoe auto-check system, CAN transceiver plays the effect of a CAN message transceiver in the entire network.
Diagnostic message sending module is the program of being edited diagnostic command by CAPL language to the diagnostic command that target ECU sends, and then by triggering the control on CANoe on Panel interface, diagnostic program is run, and sends diagnostic command to target ECU.
Diagnostic message display module shows the diagnosis message sent and accept and resolve, and its display module is that the control on CANoe on Panel interface shows equally.
Advantage of the present invention is:
(1) can carry out automatic diagnosis to vehicle electronics diagnosis, its diagnositc test efficiency far is higher than manual testing;
(2) can manual test be carried out, according to demand, diagnositc test can be carried out to ECU, improve the convenience of diagnositc test;
(3) diagnostic equipment can be replaced and diagnostic command transmission and collection are carried out to car load ECU, facilitate the test job of diagnositc test personnel.
