Embodiment Construction
[0022] The invention proposes a calibration system hardware architecture in which the calibration device and the electronic control unit are separated, and uses the calibration device as an intermediate layer between the upper computer calibration system and the electronic control unit, and solves the problem of strong coupling between the calibration system and the development of the electronic control unit. The whole process of communication between the calibration device of the present invention and the calibration system of the upper computer adopts the internationally accepted CCP protocol. When the calibration device and the calibration software of the upper computer need to communicate, the communication party is requested to send a corresponding CCP command to the receiver according to the CCP protocol. After receiving the CCP command, the party parses the command according to the CCP protocol and completes the corresponding operation.

The invention relates to a universal calibration device for protecting a vehicle electron control unit and relates to the control technology of vehicle electron. The calibration device which is designed by the invention and used as the middle layer of an upper computer calibration system and an electronic control unit is independent of the electric control unit, and comprises the calibration SCM and the double-interface RAM of an expanded CAN communication interface; the calibration SCM follows a CCP protocol and is communicated with the upper computer calibration system by the expanded CAN communication interface; calibration parameters and measuring parameters are stored in the double-interface RAM; the calibration SCM and the electric control unit share the parameters in the double-interface RAM. The calibration device has commonality which can be very conveniently integrated with the vehicle electron control unit and the upper computer calibration software (such as CANape, INCA), overcomes the defects of large developing working load and poor commonality of the prior art and improves the efficiency for the work of developing and calibration.
Description
technical field [0001] The invention relates to automobile electronic control technology, in particular to a product used in the calibration of automobile electronic control units. Background technique [0002] For modern automobiles, comfort, efficiency and safety are quite dependent on the application of various electronic control systems. There are more and more components with electronic control units (Electronic Control Unit, ECU), such as powertrain control, power management, Anti-lock braking systems, traction control, etc. are typical applications of electronic control units. At the same time, with the improvement of automobile fuel consumption requirements and emission standards, in order to meet the new standards, new sensors, actuators, and advanced control algorithms are continuously applied to the development of new electronic control units, such as: [0003] Variable structure supercharger, multi-pulse control, variable structure intake chamber, dual fuel syst...
