from the door ajar switch 28 and the inside release switch 24 according to one embodiment of the invention as shown in fig2 the logic of the controller 30 can interpret every possible combination of outputs from the door ajar switch 28 and the inside release switch 24 including output transitions from 0 to 1 and 1 to 0 to correspond to a particular state of the latch 12 and hence the associated door not shown although fig2 and the examples described below focus on components operable by the inside door handle 14 the inventive concepts are equally applicable to components operable by the outside door handle 31 where appropriate the logic of controller 30 may instruct one or more of the first and second motors 26 and 38 and the power release actuator motor 33 to unlock the latch 12 or conduct power release of the latch 12 it can be seen that in this embodiment the controller 30 logic has been programmed to provide a two pull override function for the inside door handle 14 in other words a first pull of the inside door handle 14 will send a signal from the inside release switch 24 to the controller 30 which in turn instructs the inside and outside motors 26 and 38 to remove the block or break in the inside and outside locking mechanisms 18 and 36 when the inside door handle 14 is released the controller 30 then stores data indicating that the inside door handle has been pulled once if the inside door handle 14 is pulled a second time the controller 30 determines.
