A vehicle is provided having a sensor for detecting a vehicle occupant's presence, and another sensor for detecting an owner's response with respect to automatically opening a vehicle closure panel. An actuator opens the closure panel when the occupant's presence and response are detected. A signal from an emitter outside the vehicle signals occupant presence. A photoelectric and/or optical device, audio receiver, and/or touch-sensitive sensor detects the response. The optical device projects a light beam, and breaking the beam with a gesture signals the response. An automatic closure panel opening apparatus has an RF receiver adapted to receive an RF signal to detect occupant presence, a sensor for detecting the occupant response, and an actuator for opening the closure panel when both the presence and occupant response are detected. A method for automatically opening the closure panel includes detecting an occupant presence and response, and automatically opening the closure panel when a predetermined response is detected.

Arms full vehicle closure activation apparatus and method

A door system includes a structural member and a door that is movably mounted with respect to the structural member for movement between an open position and a closed position. A spring is mounted with respect to the structural member or the door and being sufficiently positioned to bias the door toward its open position when the door is in its closed position. Active material based actuators may selectively compress the spring prior to door closure to minimize door closing effort.

Door actuation systems

A door system includes a structural member and a door being selectively movable with respect to the structural member. An actuator includes an active material that is configured to change at least one attribute in response to an activation signal. The actuator is configured such that the change in at least one attribute causes the door to move relative to the structural member.
