Abstract

The invention relates to a portable engine data standardization recording method and a device. The device comprises a man-machine interaction module used for sending an operating instruction, a microcontroller module, a power supply management module and a data storage module, wherein the man-machine interaction module can perform parameter standardization or display engine running state data based on a CCP (critical compression pressure) bottom layer agreement, the microcontroller module processes the instruction and controls other modules to complete parameter standardization and record a task, a microcontroller self CAN (microcontroller module) SCI(serial communications interface) bus module collects the data of a scene CAN bus or an LIN bus interface, the capacity of an SD card is enlarged in an outer manner through a microcontroller self SPI (serial peripheral interface) bus module, and the microcontroller module can record a controlling parameter MAP of a vehicle-mounted engine controller and a running state parameter; and the power supply management module is used for converting the electric energy of a self lithium battery into the required electric energy of each module on the system, and the data storage module is used for recording data. The recording method and the device provided by the invention can effectively solve the problem that equipment such as a notebook computer and the like is inconveniently to carry out engine parameter standardization and bus record particularly under the scurviness road environment in an engine matching testing process, and the operation feasibility and work efficiency of operators are effectively improved.

Description

technical field [0001] The invention relates to a portable engine data calibration and recording method and device, in particular to engine test parameter calibration and test data recording. Background technique [0002] At present, the functions and control strategies of automobile engine control systems tend to be complicated, and the amount of data that needs to be calibrated and recorded in the process of vehicle matching is increasing. Real-time monitoring of the working state parameters of the engine, storage of operating data, calibration and modification of the engine control MAP, can provide an intuitive data reference for the operator to analyze and improve the control strategy. During the matching test operation, the operator not only has to perform the test on the flat road, but also needs to complete the matching test for some off-road vehicles in harsh road environments such as ice, snow, desert, and mountain road. The method is limited by the harsh working e...
