1. A method for generating driving behavior guiding information in a server that communicates with a vehicular terminal and a terminal device bound with a vehicle to generate driving behavior guiding information, wherein the method comprises:

  • receiving, by the server, operating information of the vehicle, position information of the vehicle, and road condition information sent from the vehicular terminal, the vehicular terminal including;

    a vehicle operating information obtaining module connected to a vehicle-mounted self-diagnostic system of the vehicle, the vehicle operating information obtaining module including a controller area network (CAN) bus sub-module and a diagnosis sub-module that are connected to an on-board diagnostic (OBD) system of the vehicle to monitor CAN data of the vehicle and obtain the operating information of the vehicle, the operating information of the vehicle including a current vehicle speed, a current steering angle of a steering wheel of the vehicle, and current revolving speeds of tires of the vehiclea global position system (GPS) module that collects vehicle position information,a gravity sensor that collects road condition information, anda 3G module that transmits the operating information of the vehicle, the position information of the vehicle, and the road condition information to the server;

    generating, by the server, driving behavior guiding information according to the operating information of the vehicle, the position information of the vehicle, and the road condition information as received from the vehicular terminal; and

    transmitting, by the server, the driving behavior guiding information to the terminal device bound with the vehicle;

    wherein generating the driving behavior guiding information according to the operating information of the vehicle, the position information of the vehicle, and the road condition information as received from the vehicular terminal includes;

    obtaining local weather conditions of several continuous days according to the vehicle position information received from the GPS module;

    confirming a damping coefficient of a road surface via the local weather conditions received from the GPS module and the road condition information received from the gravity sensor;

    obtaining pressure values and revolving speeds of the tires of the vehicle when the vehicle travels in a normal condition according to the current vehicle speed;

    calculating current pressure values of the tires according to the revolving speeds of the tires working in the normal condition, the damping coefficient of the road surface, the pressure values of the tires working in the normal condition, the current steering angle of the steering wheel of the vehicle, a predetermined correcting parameter, and current revolving speeds of the tires, the calculating the current pressure values of the tires including;

    if the current pressure values of the tires exceed the pressure values of the tires in the normal condition, generating, by the server, the driving behavior guiding information for providing vehicle drivers with guidance to drive within a limited speed;

    orif the current pressure values of the tires are less than the pressure values of the tires in the normal condition, generating, by the server, the driving behavior guiding information for providing vehicle drivers with guidance to inflate the tires.
