A vehicle door includes a powered latch mechanism and an interior door handle having first and second sensors disposed on opposite sides of the interior door handle. The first and second sensors are configured to detect the presence of a user's hand to control operation of the powered latch mechanism. The powered latch may be unlatched if an unlatch switch is actuated and the first and second sensors detect the presence of a user's hand.

1. A vehicle door, comprising: a door structure having an interior surface; a powered latch mechanism that can be actuated to shift from a latched configuration to an unlatched configuration; an interior door handle disposed on the door structure, the handle having first and second ends attached to the interior surface and an elongated graspable portion that is spaced apart from the interior surface to define a gap, the graspable portion having an inner tubular structure, an outer cover and an intermediate space between them; the graspable portion defines a first side that generally faces the interior surface and a second side that generally faces away from the interior surface;a controller;first sensors mounted on one outer side of the inner tubular structure on the first side of the graspable portion that are configured to detect the presence of a user's hand to generate a first input to the controller;second sensors mounted on an opposite outer side of the inner tubular structure on the second side of the graspable portion that are configured to detect the presence of a user's hand to generate a second input to the controller;an unlatch switch on one of the ends of the handle that can be actuated to generate a third input to the controller; and wherein:the controller is operably connected to the powered latch mechanism, the first sensors, the second sensors, and the unlatch switch, and wherein the controller does not cause the powered latch mechanism to unlatch by shifting from the latched configuration to the unlatched configuration unless the unlatch switch is actuated to generate the third input to the controller and the first and second sensors simultaneously generate the first and second inputs to the controller to detect the presence of the user's hand. 2. The vehicle door of claim 1, wherein: the powered latch mechanism is only unlatched if the first and second sensors detect the presence of a user's hand within a predefined time interval of actuation of the unlatch switch. 3. The vehicle door of claim 2, wherein: the predefined time interval is three seconds. 4. The vehicle door of claim 1, wherein: the powered latch does not unlatch above a predefined vehicle speed unless the first and second sensors simultaneously generate first and second inputs, respectively, to detect the presence of a user's hand, and the unlatch switch is actuated twice to generate a pair of third inputs within a predefined time interval. 5. The vehicle door of claim 1, including: an acceleration sensor configured to measure lateral acceleration of a vehicle; and wherein:the powered latch does not unlatch if the acceleration sensor detects lateral acceleration above a predefined magnitude unless the unlatch switch is actuated twice within a predefined time. 6. The vehicle door of claim 1, wherein: the handle includes a force sensor that detects a force applied to the handle by a user;the powered latch does not unlatch unless the first and second sensors detect the presence of a user's hand, the unlatch switch is actuated, and the force sensor detects a force exceeding a predefined magnitude. 7. The vehicle door of claim 1, wherein: the unlatch switch is located directly adjacent the graspable portion of the door handle. 8. The vehicle door of claim 1, wherein: the unlatch switch comprises a pushbutton switch. 9. The vehicle door of claim 1, wherein: the first and second sensors comprise capacitive sensors. 10. The vehicle door of claim 1, wherein: the first and second sensors comprise mechanical switches that can be actuated by movement. 11. A vehicle door, comprising; a door structure;an interior handle having an inner tubular structure, a cover, and a space between them;capacitive sensors disposed on opposite sides of the tubular structure and an unlatch switch at an end thereof;a powered latch; anda controller that unlatches the powered latch if the capacitive sensors simultaneously detect a hand and the switch is actuated within a predefined time interval of the sensors detecting a hand. 12. The vehicle door of claim 1, wherein: the first and second sensors comprise optical sensors. 13. The vehicle door of claim 11, wherein: the switch comprises a pushbutton switch that faces away from the door structure. 14. The vehicle door of claim 1, wherein: the first and second sensors comprise pulse sensors configured to detect a pulse of a user upon contact with a user's hand. 15. The vehicle door of claim 1, wherein: the powered latch mechanism defines a locked state and an unlocked state;the powered latch mechanism shifts to the locked state from the unlocked state if the first sensors detect the presence of a user's hand while the second sensors simultaneously do not detect the presence of a user's hand. 16. The vehicle door of claim 15, wherein: the powered latch mechanism shifts from the unlocked state to the locked state if the second sensors detect the presence of a user's hand while the first sensors simultaneously do not detect the presence of a user's hand. 17. The vehicle door of claim 11, wherein: the handle includes first and second opposite ends that are secured to the door structure and a central portion that is spaced apart from the door structure to define a gap that, in use, receives a portion of a user's hand. 18. A method of controlling a powered door latch of a vehicle, the method comprising; providing a door having an interior handle including an inner tubular structure, a cover, and a space between them, the door structure further including a powered latch configured to selectively retain the door in a closed position;providing sensors on opposite sides of the tubular structure of the interior handle; andunlatching the powered latch only if a user manually actuates an unlatch switch and the sensors on opposite sides of the tubular structure of the handle simultaneously detect a user's hand. 19. The method of claim 18, including: providing a switch; and wherein:the powered latch is unlatched only if the unlatch switch is actuated within a predefined time interval of detection of a user's hand by the sensors. 20. The method of claim 18, including: measuring a velocity of the vehicle; and wherein:the powered latch is not unlatched if the vehicle velocity exceeds a predefined velocity unless the switch is actuated twice within a predefined time interval.
