Abstract

A vehicle sliding door power door lock mechanism actuating device control system having a memory feature for use with power door lock mechanisms of the type actuated by an electrically energizable actuating device to the "Lock" and "Unlock" conditions in response to respective "Lock" and "Unlock" command signals. The system is operative to effect the electrical energization of the lock mechanism actuating device in a direction to actuate the lock mechanism to the "Lock" condition upon each closure of the sliding door subsequent to an occurrence of a "Lock" command signal while the door is open.

Claims

1. A vehicle sliding door power door lock mechanism actuating device control system having a memory feature for use with power door lock mechanisms of the type actuated by an electrically energizable actuating device to "Lock" and "Unlock" conditions in response to respective "Lock" and "Unlock" command signals and operative to effect the electrical energization of the lock mechanism actuating device in a direction to actuate the lock mechanism to the "Lock" condition upon each closure of the sliding door subsequent to an occurrence of a "Lock" command signal while the door is open, comprising:

means responsive to the operation of a spring return to neutral type door lock control switch to the "Lock" position for producing and storing a "Lock" command logic signal;

means responsive to the closure of said vehicle sliding door for producing an enabling logic signal;

means responsive to said "Lock" command and enabling logic signals for producing an output electrical signal;

first means responsive to said output electrical signal for effecting the electrical energization of said lock mechanism actuating device in a direction to actuate said lock mechanism to said "Lock" condition, and

second means responsive to said output electrical signal for effecting the removal of said "Lock" command logic signal from storage.

2. A vehicle sliding door power lock mechanism actuating device control circuit having a memory feature for use with power door lock mechanisms of the type actuated by an electrically energizable actuating device to "Lock" and "Unlock" conditions in response to respective "Lock" and "Unlock" command signals and operative to effect the electrical energization of the lock mechanism actuating device in a direction to actuate the lock mechanism to the "Lock" condition upon each closure of the sliding door subsequent to an occurrence of a "Lock" command signal while the door is open, comprising:

means, including a first timer means, responsive to the operation of a spring return to neutral type door lock switch to the "Lock" position for producing and storing a "Lock" command logic signal;

means responsive to the closure of said vehicle sliding door for producing an enabling logic signal;

means, including a second timer means, responsive to said "Lock" command and enabling logic signals for producing an output electrical signal;

first means responsive to said output electrical signal for effecting the electrical energization of said lock mechanism actuating device in a direction to actuate said lock mechanism to said "Lock" condition; and

second means, including said first timer means, responsive to said output electrical signal for effecting the removal of said "Lock" command logic signal from storage.

3. A vehicle sliding door power lock mechanism actuating device control circuit having a memory feature for use with power door lock mechanisms of the type actuated by an electrically energizable actuating device to "Lock" and "Unlock" conditions in response to respective "Lock" and "Unlock" command signals and operative to effect the electrical energization of the lock mechanism actuating device in a direction to actuate the lock mechanism to the "Lock" condition upon each closure of the sliding door subsequent to an occurrence of a "Lock" command signal while the door is open, comprising:

means responsive to the operation of a spring return to neutral type door lock switch to the "Lock" position for producing a logic signal;

means including timer circuit means responsive to said logic signal for producing and storing a "Lock" command logic signal;

means responsive to the closure of said vehicle sliding door for producing an enabling logic signal;

means responsive to said "Lock" command and enabling logic signals for producing an output electrical signal;

first means responsive to said output electrical signal for effecting the electrical energization of said lock mechanism actuating device in a direction to actuate said lock mechanism to said "Lock" condition; and

second means including said timer circuit means responsive to said output electrical signal for effecting the removal of said "Lock" command logic signal from storage.

4. A vehicle sliding door power lock mechanism actuating device control circuit having a memory feature for use with power door lock mechanisms of the type actuated by an electrically energizable actuating device to "Lock" and "Unlock" conditions in response to respective "Lock" and "Unlock" command signals and operative to effect the electrical energization of the lock mechanism actuating device in a direction to actuate the lock mechanism to the "Lock" condition upon each closure of the sliding door subsequent to an occurrence of a "Lock" command signal while the door is open, comprising:

a J-K flip-flop circuit having J and K input terminals and Q and Q output terminals;

means responsive to the operation of a spring return to neutral type door lock switch to the "Lock" position for producing a logic 1 signal and for applying said logic 1 signal to said J input terminal of said J-K flip-flop circuit;

means including timer circuit means for effecting the transfer of said logic 1 signal applied to said J input terminal of said J-K flip-flop circuit to said Q output terminal thereof whereby a logic 0 "Lock" command signal is present upon the J-K flip-flop circuit Q output terminal;

means responsive to the closure of said vehicle sliding door for producing an enabling logic signal;

means responsive to said "Lock" command and enabling logic signals for producing an output electrical signal;

first means responsive to said output electrical signal for effecting the electrical energization of said lock mechanism actuating device in a direction to actuate said lock mechanism to said "Lock" condition; and

second means including said timer circuit means responsive to said output electrical signal for effecting the removal of said logic 0 "Lock" command signal from said Q output terminal of said J-K flip-flop circuit.
