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.

Abstract: 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.

Abstract: 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.

Abstract: A speedometer includes a function storage device, which has stored therein four conversion functions, a selector, which provides four options corresponding to the four conversion functions in the function storage device, and a microprocessor, which counts pulse signals sent by the sensor device of the motor vehicle to obtain a counted total value, selects the corresponding conversion function from the function storage device corresponding to the option selected through the selector according to the quantity of poles (two, four, eight or sixteen) on the drive shaft of the motor vehicle, and puts the counted total value into the selected conversion function for calculation to obtain a car speed value.

Abstract: A parking lot reservation system in which each vehicle sends to a remote server through a GPRS module a park reservation request carrying the information of the ID code and current location of the vehicle and specific conditions, and the remote server searches a parking lot database to select the qualified parking lot information subject to the park reservation request and then sends a reservation command to the parking lot computer of the associated parking lot through the Internet to finish the reservation. After success of reservation, the parking lot computer sends a response message indicative of successful reservation to the GPRS module of the vehicle via the remote server.

Abstract: Disclosed is a vehicle security system, which includes a security controller and a remote controller. The security controller is electrically connected to sensors and alarms, respectively, and has a memory storing an anti-thief alert grade table. The anti-thief alert grade table records at least two alert grades each having a respective sensitivity default value corresponding to each sensor. The sensitivity default value of each alert grade for each sensor defines the critical actuation value of the respective sensor for the respective alert grade. The remote controller has a control button for pressing to control the security controller to enter the desired alert grade of the alert mode.
