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