<p><P>PROBLEM TO BE SOLVED: To realize a door lock system at a low cost by reducing the amount of harness to be used in the door lock capable of locking and unlocking a back door of a vehicle. <P>SOLUTION: When a switch SW is once closed, the first controlling means 40 detects that opening operation of an opening door handle 11 is made, a driving current is supplied to an unlatching motor 33 for a time sufficient to release a constrained state of the back door 10. The first controlling means 40 is connected to the second controlling means 60 through the harness 50. The second controlling means 60 supplies power to the first controlling means 40 through the harness 50 when the back door 10 is in an unlocking state, and to the contraries, in the case the back door 10 becomes in a locking state, power supply to the first controlling means 40 is stopped. <P>COPYRIGHT: (C)2006,JPO&NCIPI</p> |
