Abstract:
PURPOSE: A synchronization method in an automotive network and an apparatus thereof are provided to output a beacon signal for synchronization only when a vehicle passes through a special point in the automotive network. CONSTITUTION: A vehicle detection sensor(20) detect vehicles. The charging unit(11) of a synchronization device(10) charges electrical energy according to the electrical signal of the vehicle detection sensor. If a signal is generated according to the vehicle detection, a synchronous signal generator(12) creates a synchronous signal or a message signal including predetermined data. A transceiver(14) transmits the beacon signal of the synchronous signal generator. In case the vehicle passes through the installation position of the synchronization device, synchronization operates with the transmission of the beacon signal.

PURPOSE: An opening and closing detection apparatus using a sensor and a method are provided to protect children by a driver and obtain a convenience in a safe driving, by mounting the opening and closing detection apparatus using the sensor and the method on a school bus. CONSTITUTION: An opening and closing detection apparatus using a sensor comprises a medium showerhead(100), a medium movement route unit, a sensor unit(300), and a informative section(400). The medium showerhead can spray the medium. The medium movement route unit changes its rout according to the status of an opening and closing object, and changes the status of the medium according to the changed route. The sensor unit measures the status of the medium which moves along the medium movement route unit, and produces the status information. The sensor unit includes the sensor measuring the status of the medium. The sensor measures at least one among the mass, volume, temperature, or pressure of the medium. The sensor senses the range of change of bending according to airflow of the air medium. A sensor measuring the range of change of bending includes the piezoelectric sensor. The informative section provides the status information of the opening and closing object to the user by using the status information.
Abstract:
PURPOSE: Diagnosing apparatus and method of an ECU for a vehicle are provided to track and analyze the reason of the ECU using only information on a map file regardless of a vehicle manufacturer or a part supplier. CONSTITUTION: A diagnosing apparatus(200) of an ECU for a vehicle comprises a map file requesting unit(210), a map file receiving unit(220), a diagnosing/controlling unit(230) and a memory unit(240). The map file requesting unit receives information used for loading a map file from an ECU. If there are no map files corresponding to the information, the map file requesting unit calls on a database server to send map files. The map file receiving unit receives the corresponding map file from the database server. The diagnosing/controlling unit receives the address of the function of a vehicle control S/W from the ECU. The diagnosing/controlling unit compares the address of the function with the information of the map file to determines the function of the vehicle control S/W that is requested at present.
