The invention provides a vehicle-driving control method for intelligent fault diagnosis and driving behavior analysis, comprising the following steps of: reading a fault code inside an
electronic control unit of an engine of a vehicle and analyzing the fault code into fault information of the vehicle by connecting a
microcontroller with a vehicle diagnosis interface through a K
line driver, and displaying the vehicle fault information on an LCD (
Liquid Crystal Display) screen of a man-
machine interaction unit; acquiring real-time state information of the vehicle by connecting the
microcontroller with the vehicle diagnosis interface through a CAN (Controller
Area Network) driver, and storing the acquired real-time state information into a data storage according to a fixed format;
copying data stored in the data storage into a
USB flash disk through a
USB interface so as to carry out
data analysis by
application software matched with a device, and providing a driving behavior analysis result. The invention realizes the real-
time data acquisition and storage functions of the integral vehicle so that the bad driving behaviors of drivers are corrected in time, also provides real data foundation for accurate fault maintenance and ensures that the comparison of real
oil consumption and oiling quantity is evidence-based by providing a display function of a regional total oil injectionquantity.
