Abstract: A sensitive locking control device for a vehicle has a server mounted in the vehicle and a portable proximity controller. The server continuously emits a detecting signal trying to detect whether the proximity controller is within an effective range of the server. When the proximity controller responds to the server by sending a confirmation signal, the server is unable to automatically lock or unlock a vehicle door or a trunk lid without using a key, or to enable or disable a vehicle security system.

Abstract: A rearview mirror used inside a car is disclosed to include a casing, which defines an accommodating chamber, a data storage device, which has stored therein MP3 music files, and a music player module, which is received in the accommodating chamber of the casing, having a digital music decoder electrically connectable to the data storage device for fetching storage MP3 music files and decoding fetched MP3 music files, and a Frequency Modulation (FM) transmitter electrically connected to the digital music decoder for wirelessly send out the decoded MP3 music files.

Abstract: An air pressure induction type vehicle anti-thief device includes an on-vehicle main unit installed in a motor vehicle adapted to detect variation of air pressure in the inside chamber of the motor vehicle through an air pressure sensor and to drive an alarm to output an alarm signal when the amount of variation of transient variation of air pressure surpassed a predetermined safety air pressure value.

Abstract: A vehicle anti-thief device includes an on-vehicle main unit, an on-vehicle bluetooth module, and a bluetooth mobile terminal to be carried by the user. When the user leaved the car, the on-vehicle bluetooth module receives no signal from the bluetooth mobile terminal and then drives the on-vehicle main unit into alarm mode. When the user with the bluetooth mobile terminal entered the communication radius of the bluetooth module, the bluetooth mobile terminal connects the on-vehicle bluetooth module wirelessly and gives a disarm signal to disarm alarm setting of the on-vehicle main unit.

Abstract: A radar device for use in backing up a vehicle is disclosed herein. A plurality of wave sensors is installed on a rear portion of a vehicle for detecting an obstacle therebehind. A master controller has a plurality of transceiver circuits and a microprocessor connected to the plurality of transceiver circuits. Each transceiver circuit corresponds to one of the plurality of wave sensors. The microprocessor activates the plurality of transceiver circuits to drive the plurality of wave sensors for transmitting and receiving ultrasound wave signals thereby determining the location of the obstacle. A location display device is connected to the master controller for receiving and decoding data related to the location of the obstacle thereby indicating the direction of the obstacle and displaying in numerical form the distance between the obstacle and the vehicle.
