A vehicle door includes a powered latch configured to selectively retain the door in a closed position when the powered latch is latched, and permits the door to be opened when the powered latch is unlatched. The vehicle door further includes an exterior door handle having an outer side that faces away from the door structure, and an inner side that is spaced apart from an outer surface of the door to define a gap. A force sensor on the exterior door handle detects impact forces on the handle. The door also includes an unlatch switch that can be actuated by a user to request unlatching of the powered latch. A controller is configured to deny an unlatch request generated by actuation of the unlatch switch if the force sensor detects an impact on the exterior handle.

1. A vehicle door comprising: a door structure having an outside;a powered latch configured to selectively retain the door in a closed position when the powered latch is latched, and permit the door to open when the powered latch is unlatched;an exterior door handle defining a generally tubular construction mounted to the outside of the door structure and defining an outer side spaced apart from an inner side to define a gap therebetween;the handle further includes a movable member disposed on the inner side;a variable resistance bend sensor extending within the gap along the outer side of the exterior door handle such that an impact force applied to the outer side of the handle changes an electrical resistance of the bend sensor;an unlatch switch positioned within the gap and being operatively actuated by the movable member;a controller operatively connected to the unlatch switch and the bend sensor; and wherein: actuation of the unlatch switch causes the powered latch to unlatch if a force applied to the bend sensor on the outer side of the handle remains in a range that is below an amount of change required to indicate that an impact has occurred; andactuation of the unlatch switch does not cause the powered latch to unlatch if a change in electrical resistance of the bend sensor sufficient to signal a side impact occurs within a predefined time interval after actuation of the unlatch switch. 2. The vehicle door of claim 1, wherein: the bend sensor is configured such that bending of the sensor due to a side impact on the handle causes an increase in the electrical resistance of the bend sensor. 3. The vehicle door of claim 1, wherein: the exterior door handle defines an internal cavity and an outer side wall having an inner side facing the internal cavity, and wherein the bend sensor includes an elongated sensor member disposed on the inner side of the outer side wall. 4. The vehicle door of claim 3, wherein: the internal cavity is watertight. 5. The vehicle door of claim 1, wherein: the unlatch switch includes a second conductor that is connected to a first conductor when the unlatch switch is not actuated, and wherein the second conductor is connected to a third conductor when the unlatch switch is actuated. 6. The vehicle door of claim 5, wherein: the powered latch comprises a controller that determines if the unlatch switch has been actuated by detecting an edge transition upon connecting the second conductor to the third conductor. 7. The vehicle door of claim 6, wherein: the controller does not unlatch the powered latch unless the second and third conductors of the unlatch switch are connected. 8. The vehicle door of claim 1, wherein: the exterior door handle has an inner side, and includes an elongated movable member disposed on the inner side, and wherein the movable member engages the unlatch switch upon movement of the movable member.
