Abstract: A method and system for controlling a vehicle. The method comprises: a mobile terminal (301) receives a vehicle control instruction (101) issued by a user, the mobile terminal (301) transmits a first control instruction to a diagnostic card (302) on the basis of the vehicle control instruction to request for control of the vehicle (102), the diagnostic card (302) parses the received first control instruction to acquire a parsing result (103), and the diagnostic card (302) controls the vehicle according to the parsing result (104). This allows a backseat passenger to control the vehicle via the mobile terminal (301), while at the same time prevents a driver from having to divert attention to helping the backseat passenger in making an adjustment, thus facilitating the backseat passenger in controlling the vehicle.

Abstract: A vehicle information acquisition method and device: a diagnostic device collects vehicle information; and a mobile intelligent terminal is able to be in communication with the diagnostic device via a WLAN, and accesses the diagnostic device via a webpage to acquire the vehicle information displayed on the webpage. Thus, a user can acquire vehicle driving information in real time simply by utilizing the mobile intelligent terminal to access a WLAN. The present invention is more convenient to use and is applied in a wider range compared with the vehicle information acquisition method in the prior art.
