<p>PROBLEM TO BE SOLVED: To simplify electrical constitution without damaging functional safety operation. SOLUTION: The locking system has respective one door lock 5, a central locking device having electrical adjusting members arranged in response to one door lock to each door lock respectively and an operation control circuit 7 for operating and controlling the central locking device in each motor-vehicle door. The operation control circuit 7 has a bus system 9 for transmitting information. The bus system 9 is operated by circuit multiplexing system elements 11 housed in one adjusting member at every one respectively. Microcontrollers, motor drivers and control sensors housed in each adjusting member are encapsulated in the operation control circuit 7 regarding each motor-vehicle door lock. The circuit multiplexing system elements 11, the microcontrollers and the motor drivers are arranged on common circuit boards 15 housed in the adjusting members or the motor-vehicle door locks. The circuit board 15 is housed in a capsule for dustproof and moisture-proof treatment.</p> |
