Title       Design of a data acquisition system for EPB 
Abstract
In this paper, an electronic parking data acquisition system was the object of our study, access to information on a large number of domestic and foreign automotive electronic technology, introduced the development of domestic and foreign automotive electronics, elaborated on the basic principles of electronic parking system, electronic parking parking systems and traditional systems are compared, given their advantages and disadvantages. Mastered the basic electronic parking system on the working process to determine the number and type of data to be collected the data acquisition system, using Visual Basic design of the electronic parking brake system of data collection platform software, the PC and electronics Real-time communication parking brake system, the program in accordance with the CAN-bus platform for data transmission protocol, can receive real-time data from the CAN bus platform information, but can also send control information to the electronic parking system; program can receive the data recording and playback, in the manner of graph display.
Finally, in the experimental stage of data collection software for the testing and debugging, it can meet the requirements of the relevant technology.
