  • Patent number: 4537049
    Abstract: A power door lock control for vehicles includes a manually operable member which may be the conventional lock-unlock button. One door contains an electrically powered mechanism which operates a locking bolt. Connected to the mechanism is a contact which is cooperable with a second contact on the vehicle body when the door is closed. A pulse circuit in the vehicle is actuated when the driver presses the lock button toward its "locking" position, and supplies spaced pulses to the body contact. The pulses continue at a very low duty cycle, so as to draw minimal current, until the door is closed at which time the door contact and body contact engage one another, thereby completing a circuit from the pulse generator to the powered mechanism. This in turn operates the locking bolt to secure the door. At the same time, a current sensing circuit in the vehicle detects that a pulse of current has flowed through the powered mechanism.
