Abstract

The invention discloses a CAN (Controller Area Network) bus log file acquisition device and system used for a vehicle, and the vehicle. The device comprises a CAN bus interface, a USB (Universal Serial Bus) interface, a storage module and a control module, wherein the CAN bus interface is connected with a vehicle CAN bus; the control module is independently connected with the CAN bus interface, the USB interface and the storage module; the control module is used for obtaining log data on the vehicle CAN bus in real time through the CAN bus interface, and storing the log data into the storage module; and when the control module detects that the USB interface is connected with terminal equipment, the USB interface is controlled to work in a USB disk way for the terminal equipment to read log data. By use of the device, the log data on the CAN bus during the running time period of the vehicle on a road can be integrally stored, when the vehicle needs to repaired or detected, the log data can be imported into the terminal equipment through the USB interface, and engineers can more accurately and quickly position fault reasons.

Description

Technical field [0001] TECHNICAL FIELD The present invention relates, in particular, relates to a vehicle CAN bus log file retrieval means, and a vehicle CAN bus acquisition system log file. Background technique [0002] With the development of the vehicle industry, electronics and sensors installed on more and more vehicles, more and more complex. Many sensors are critical for data transmission via CAN (Controller Area Network, a controller area network) bus. ECU (Electronic Control Unit, the electronic control unit) via CAN bus interface module CAN bus data transceiver in real time, reading the CAN bus operating condition sensors and electronics on a vehicle according to a control command issued algorithm, to ensure that the various functions of the vehicle completed. When during the operation, when the ECU when certain sensors to monitor the problem, it will display a warning message on the man-machine interface of the vehicle to alert drivers according to the warning level ch...
