Abstract

The present invention relates to a vehicle information terminal, in particular to a vehicle information terminal with a GPS, a BeiDou Navigation Satellite System and a mobile station. Technical schemes of CAN and LIN buses in a system are as follows: realization of information acquisition, information transmission, and remote diagnosis of a vehicle condition; realization of navigation, entertainment, communication, diagnosis, auxiliary driving, and drive recording; and data collection, storage, display, and remote monitoring of a whole vehicle. Based on the combination of BeiDou positioning, GPS positioning and mobile station positioning, following functions are realized: vehicle positioning, vehicle running path storage, vehicle running path playback, vehicle running path rationality analysis, generation of various parameters in vehicle running, generation of an analysis result in contrary to a standard model, and reminding and correction of a driving behavior of a driver.

Description

1. Technical field [0001] The patent of the present invention relates to a vehicle-mounted information terminal, in particular to a vehicle-mounted information terminal with GPS, Beidou and mobile station. 2. Background technology [0002] In the future, the car will develop into a mobile communication terminal, and radio communication is one of the important technologies to realize this process. Car-centric communication includes not only the wireless interconnection of electronic units such as sensors, monitors, and control devices in the car, but also the communication between cars and between cars and roads. In order to achieve higher-speed connectivity, it is necessary for in-vehicle information terminals to adopt higher wireless communication standards such as WAVE or WiMAX. The reliability problem of in-vehicle connection can be solved by applying wireless communication technologies such as UWB (UltraWideBand). And it can realize wireless connection like Bluetooth. ...
