Therefore, the method becomes the first choice for calibrating the working software of the controller.
In the development and verification stage of the controller software, a calibration engineer adjusts and optimizes a control system by modifying the characteristic value of the functional algorithm, and simultaneously verifies whether modifying the characteristic value can cause the controller to enter a fault state and generate a fault code. If the controller fails, a UDS instruction needs to be sent to read a fault code and freeze frame information in the controller so as to evaluate and analyze the root cause of the failure. However, the INCA software only provides simple ProF service, and cannot meet the functional requirements of reading and analyzing fault information by sending a UDS instruction.
Therefore, the calibration engineering needs to purchase and carry other diagnostic tools additionally and install corresponding diagnostic software to fulfill the requirements, and since the diagnostic software and the hardware are very expensive, the development and verification cost of the controller is increased firstly. Secondly, the calibration engineer needs to switch the operation back and forth between the INCA software and the special diagnostic software, so that great inconvenience is brought to the calibration development work.
Therefore, it is necessary to provide a new method and system for reading and analyzing the failure information of the controller based on the INCA software to solve the above technical problems.
