A handle / liftgate assembly for a door of a vehicle is mounted to a handle region of a vehicle door and includes a handle control and a handle sensor. The handle control is responsive to the handle sensor to detect the presence of or proximity of a user or operator at the vehicle door. The handle control actuates a door latch of the vehicle door to open the vehicle door independent of a door zone module or passive entry system of the vehicle door.

A flush door handle includes a powered actuator that shifts the handle from a fully retracted position to an intermediate position. A user can then grasp the handle, and pull the handle to a fully open position to thereby unlatch the door latch. After a user releases the handle, it shifts to a closed position due to spring force or a powered actuator. The door latch may also comprise a fully powered version wherein the handle shifts from a closed position to an open position, and a powered door latch releases the door latch if predefined conditions are detected.

A handle 16 for exterior use in a vehicle to authorize a mechanism (18) to unlatch an access door has a structural part (34); a cover (36); and a pair of sensors or switches (28, 29) between the structural part (34) and the cover (36). A first sensor or switch (28) to interact with one or more fingers of a user's (26) hand (2) and a second sensor or switch (29) spaced from said first sensor (28) to be activated by a user's (26) different finger or the user's (26) thumb. The combination of the two switches or sensors (28, 29) signal the mechanism (18) to unlatch the access door and wherein the activation of only the second sensor or switch (29) in the absence of touching the first sensor or switch (28) authorizes a mechanism (18) to lock the access door. Preferably, the first and second sensors or switches (28, 29) are electrically coupled such that activation of both authorizes an unlatching of the access door while the activation of only the second sensor or switch (29) authorizes a lock only feature. Accordingly, the second sensor or switch (29) changes authorization from unlatch to lock dependent on the use or non-use of the first sensor or switch (28).

A vehicle door security system comprising at least one deadbolt and respective operational elements, wherein the deadbolt secures at least one of a pivoting door and a roll up cargo door.

An apparatus automatically locks the doors of a vehicle based on mutual communications between a portable unit and a vehicle-side control unit. After the doors are closed and locked after all the passengers get off the vehicle, the user of a portable unit unlocks the doors in order to allow a person without the portable unit to fetch something left in the vehicle. After the person opens a door, takes whatever he or she needs, and closes the door, the doors are automatically locked. When a door sensor is operated to unlock the doors, and one of the doors is opened, a memory means stores information indicating that the portable unit is present in a predetermined range outside of the vehicle. If the memory means stores information that the doors are unlocked, then the doors are automatically locked.

The invention relates to an external door handle for the side door, rear door or boot of a motor vehicle, said door handle being fitted with a flap (1) that retracts automatically when the handle is used. The flap is fitted with a sensor (5) which detects the presence of a hand opposite said flap. When the flap is not in use, it is closed in such a way as to be perfectly flush with the external surface (2) of the door and it is held in position by a spring recall system. An actuation device, which is controlled by a computer, is designed to retract the flap at the appropriate moment in order to provide access to the door opening control (8). Said flap system can be connected to an electric-or mechanical-type-opening control. The inventive handle affords the advantage of being very practical to use and having a value-enhancing style and appearance.
