Process for triggering an electrically actuated motor vehicle door lock or the like
First Claim
1. Process for triggering an electrically actuated motor vehicle door lock of the type having an actuating handle, a rotary latch, a detent pawl for holding the rotary latch in a closed position, and an electric drive which is displaceable from an initial, rest position for shifting of the detent pawl, said detent pawl being raisable by the drive off of the catch of the rotary latch, at least one detent pawl switch for indicating a position of the detent pawl, and a handle switch for indicating an actuation state of the actuating handle, comprising the steps of:
- triggering the drive by actuation of said actuating handle;
triggering a switching function only when actuation of the actuating handle is maintained for at least a predetermined minimum time;
always returning of the drive to the initial, rest position after actuation of the actuating handle has been terminated, even if such occurs in less than said predetermined minimum time; and
turning off the drive upon returning of the drive to said initial rest position.

Abstract
A process for triggering a electrically actuated motor vehicle door lock by a mechanical or electromechanical actuating handle. In this process, triggering takes place such that the electric motor drive always returns to an initial rest position after initial triggering and that actuation of the actuating handle for less than a minimum time does not trigger a switching function. Thus misactuations are unlikely. The operating characteristics of the motor vehicle door lock which is controlled using this process is matched as much as possible to the operating characteristics of mechanical or electromechanical motor vehicle door locks of conventional design. This facilitates acceptance among customers and prevents misoperations.

14. In an electrically actuated motor vehicle door lock of the type having an actuating handle, a rotary latch, a detent pawl for holding the rotary latch in a closed position, and an electric drive which is displaceable from an initial, rest position for shifting of the detent pawl, said detent pawl being raisable by the drive off of the catch of the rotary latch, at least one detent pawl switch for indicating a position of the detent pawl, and a handle switch for indicating an actuation state of the actuating handle, a control logic and a power supply, a control circuit comprising:
-
a connection of the control logic to terminals of the power supply as well as to the detent pawl switch, the drive, a common pole of the handle switch, a negative switch pole of the handle switch, and a positive pole of the handle switch, a means for trigger the drive in response to actuation of said actuating handle, a means for trigger a switching function only when actuation of the actuating handle is maintained for at least a predetermined minimum time, a means for always returning of the drive to an initial, rest position after actuation of the actuating handle has been terminated, even if such occurs less than said predetermined minimum time, and a means for turning off the drive upon returning of the drive to said initial rest position. - View Dependent Claims (15, 16, 17)
