Capacitive proximity switch

A capacitive proximity switch for detecting the change in the capacitance relative to a setpoint capacitance by the approach or retreat of an object in the sensitive area of a proximity switch, especially for use in the door handle of a motor vehicle, provides reliable error detection and error suppression at a fundamentally high sensitivity of the capacitive proximity switch by utilizing an evaluation unit that evaluates a measured value of the change in capacitance over time and depending on the time behavior of the measured value activates changes the operating threshold from a first threshold (which can be caused by a false object coming into or out of the sensitive area of the proximity switch) to a higher second threshold which can be reached only at a relatively greater change in capacitance caused by a target object coming into or out of the sensitive area of the proximity switch.

Automatic vehicle door locking/unlocking apparatus

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.

Rotating catch lock, specially for motor vehicles

The invention relates to a rotating catch lock, wherein a closing member (10) interacts with a catch (20), which can be rotated between a closing position accommodating the closing member (10) and an open position which releases said member. The catch (20) is force-loaded (22) in an open position and is held by a spring-loaded (33) rotating latch (30) in the close position. Said latch (30) is moved by a motor (50) between the locking position retaining the catch (20) and a stand-by release position in which the spring-loaded latch (30) is propped up by the catch (20) as long as it remains in an open position. In order to use small compact motors (50), the invention provides that the stored energy (61) exerted by an energy storage mechanism (60) is transmitted to the latch (30) via a storage lever (40). Normally, the latch (30) is shifted into its stand-by position by the storage lever (40). When the latch (30) is in a stand-by position, the storage lever (40) is supported on a control tappet (51) which is rotationally driven by the motor (50). The motor (50) can be driven by an electrical control logic in both a forward mode (56) unloading the energy storage (60) and a reverse mode (56') loading the energy storage (60), i.e. in opposite directions. In the reverse mode (56') the control tappet (51) releases the latch (30), moves towards the storage lever (40) and guides it back into a starting position which corresponds to the stand-by position of the latch (30).

Passive entry system for automotive vehicle doors

A passive entry system for an vehicle door requires no active operator input to gain entrance to the vehicle. A door module recognizes the signal transmitted by an authorized key fob to identify the operator of the vehicle. The authentication of the operator coupled with the operator touching a sensor on the door to be opened actuates a release actuator that unlatches the selected door. The spring-load provided by the door seal will pop the door open from the closed position. A key cylinder, which can be located substantially anywhere on the door, is coupled mechanically to the release latch for use if the battery is weak and cannot activate the release actuator. An LED signals the state of the opening sequence for the door. The fixed door handle can incorporate a membrane switch or a capacitive sensor to indicate the selection of the door by the operator when touched.
