An accurate positioning system installed in a vehicle is disclosed to include a GPS, a Gyro sensor, a vehicle speedometer, and a controller. When the GPS outputs a next GPS coordinates, the controller calculates a next reference coordinates subject to the azimuth signal outputted from the Gyro sensor and the vehicle speed signal outputted from the vehicle speedometer and calculates the distance between the next GPS coordinates and the next reference coordinates, and then assigns the GPS coordinates to be the next accurate coordinates for output when the distance between the next GPS coordinates and the next reference coordinates surpasses a reference distance, or assigns the next reference coordinates to be the next accurate coordinates for output when the distance between the next GPS coordinates and the next reference coordinates is smaller than or equal to the reference distance.

Accurate positioning system for a vehicle and its positioning method

An in-vehicle computer system includes a host computer, a mode switch and a backup microprocessor. When the host computer functions ordinarily, the mode switch is in a regular mode as a default, and the host computer uses various graphical interfaces on a display to control the operations of electronic devices implemented in a vehicle. The electronic devices can include a digital versatile disc (DVD) player, an MP3 player and a global positioning system (GPS). When a total failure of the computer occurs, the mode switch is switched to a backup mode, and the host computer is replaced by the backup microprocessor to control a backup graphical processor to extract backup graphical interfaces from a backup storage medium for graphical processing and further presentation on the display. Thus, a driver can continuously control the corresponding electronic devices through the backup graphical interfaces on the display.

In-vehicle computer system

In a vehicle anti-theft system, a vehicle-mounted mainframe downloads a sole identification code, serving as a control identification code, and transfers the sole identification code into a part as a part identification code. The vehicle-mounted mainframe determines if the control identification code is obtained when the vehicle is activated. If yes, the vehicle-mounted mainframe sends a request command to the part to obtain the part identification code. The vehicle-mounted mainframe determines if the part identification code meets with the control identification code. If yes, the vehicle-mounted mainframe produces a normal operation signal to enter a normal operational mode and feedbacks the identification code to the customer service center. The customer service center checks with a database for stolen events. If an event of vehicle stolen is found, subsequent procedures are taken; otherwise, the vehicle-mounted mainframe transfers an abnormal signal to the customer service center for proceeding with subsequent procedures.

Vehicle anti-theft system and method

A vehicle navigation system with a display correction and the display correction method thereof, which first extracts a current display location and corresponding road links, next extracts a next vehicle location and selects all road links ranging within 25 meters from the next vehicle location to generate a first set of road links, next generates a second set of road links from the first set of road links based on an angle of driving direction generated by the gyroscope, next computes vertical distances from the next vehicle location to the second set of road links and selects a road link with a shortest vertical distance, and sets a projection point of the next vehicle location on the road link with the shortest vertical distance to become a next corrected location and displays the vehicle sign on the display screen at a next display location corresponding to the next corrected location.

Vehicle navigation system with a display correction and display correction method thereof

A vehicle navigation control system and method in which the system includes a communication bus, a navigation system, a display device, and a vehicle control computer. The navigation system is connected to the communication bus to provide navigation information. The display device displays a human machine interface and one item of prompt information. The vehicle control computer controls vehicle devices of the vehicle by means of the human machine interface displayed on the display device, fetches the navigation information from the navigation system via the communication bus, converts the fetched navigation information into an item of prompt information, and outputs the converted prompt information to the display device for display during display of the human machine interface.
