Abstract

The invention discloses a system and a method for automatically calibrating the dynamic performance of new energy vehicles on the basis of CCP [CAN (controller area networks) calibration protocols] and sensors. The system comprises a CCP calibration device, the measuring sensors, calibration databases and automatic analysis and calibration programs. The method includes steps that 1, initial data are computed by the aid of a computer according to selective types, and data are written into VCU (vehicle control units) by the aid of CAN network analysis programs; 2, CCP calibration systems comprise CAN network analyzers and CCP calibration software; 3, messages of multi-channel CAN are simultaneously received and transmitted by the aid of the CAN network analyzers; 4, A2L files and DBC (database computer) files are parsed by the aid of the CCP calibration software; 5, the measuring sensors include vehicle speed sensors, acceleration sensors and tilt angle sensors; 6, the calibration databases include calibration data acquisition databases and calibration data optimization databases; 7, the automatic analysis and calibration programs include data analysis programs and calibration parameter optimization programs. The system and the method have the advantages that calibration workload can be relieved to a great extent, the manual analysis and computation time can be shortened to a great extent, and the calibration accuracy and efficiency can be improved.

Description

technical field [0001] The invention relates to a system and method for automatically calibrating the dynamic performance of new energy vehicles based on a CCP protocol and a sensor, and belongs to the technical field of automatic calibration of dynamic performance of new energy vehicles. Background technique [0002] At present, with the continuous increase of vehicles and the increasingly complex and perfect functions, it is becoming more and more difficult to calibrate vehicles. Manual calibration requires a large workload and repetitive labor, requiring a lot of labor costs, and hardware The cost is high and it is difficult to popularize. In addition, manual calibration for a long time will lead to decreased concentration and low efficiency, and the adjustment of data can only be based on feeling, without organization, low efficiency and poor accuracy when calculating a large amount of data, unable to remember a large amount of data, and memory deviation may occur . Fo...
