摘要:
A vehicle security arrangement includes at least one functional control unit, which provides a first code word; a theft protection control unit, which is coupled via a bus to the at least one functional control unit; and at least one input unit, which transmits to the theft protection control unit a second code word which the theft protection control unit forwards to the at least one function control unit. The theft protection control unit may initiate the provision of the first code word and the second code word. In the at least one functional control unit, a comparison of the first code word of the at least one functional control unit with the second code word takes place. In case of agreement between the first code word and the second code word, the at least one functional control unit enables itself.

An access- and starting/driving-authorization system for a motor vehicle, having a portable transponder and a control unit accomodated in the motor vehicle, in order to control the smart master-key system and the engine control unit. In inquiry/response dialogs, the transponder and the control unit enabling or blocking access to the motor vehicle, and the starting and driving of the motor vehicle, using sets of code information that are matched to each other. Starting and driving the motor vehicle after forcibly entering the motor vehicle and replacing the engine control unit, including a vehicle immobilizer and a transponder of the control units relevant for starting and driving, is prevented in that the enabling of the motor-vehicle to be started and driven, after a successful starting/driving-authorization inquiry/response dialog, is rendered dependent on a preceding, successful access-authorization inquiry/response dialog.

The invention relates to a circuit for controlling an electrically activated motor vehicle door lock or the like, with a lock latch (1) and a detent pawl (2) which keeps the lock latch (1) in the closed position and with an electric motorized auxiliary closing drive (4) which is turned on after the lock latch (1) has reached a preclosing position and then moves the lock latch (1) by motor into the main closing position, there being a switch (16) which recognizes the preclosing position, especially a lock latch switch which scans the position of the lock latch (1). The structure of the circuit is especially simple in that the negative pole (18) of the auxiliary closing drive (4) is always connected to ground or negative potential and the positive pole (19) is switched and is either at the positive potential of the vehicle voltage or at ground or is floated and that there is only one switch (16) and the switch (16) is between the ground and a switch terminal (20) and causes switching of the auxiliary closing drive (4). Here it is especially feasible if the auxiliary closing drive (4) shuts off automatically when the lock latch (1) reaches the closed position, especially when the overstroke position of the lock latch (1) which is somewhat on the other side of the closed position is reached, when therefore the positive pole (19) of the auxiliary closing drive (4) is then at ground or negative potential or is open. This applies especially when the criterion for shutting off the auxiliary closing drive (4), when the closed position is reached, especially when the overstroke position of the lock latch (1) which is somewhat on the other side of the closed position is reached, is the power consumption of the auxiliary closing drive (4).

A device for locking and unlocking a door, in particular a motor vehicle door, has an electric lock and a door handle, with the transmission of query information to a portable electronic authorization ID means being initiatable via a control unit provided for the door when the door handle is operated out of the resting position in opposite directions, with the authorization ID means causing the transmission of identification information on receipt of the query information, and with the control unit comparing the identification information received with predetermined authorized identification information and, if it agrees with some of the predefined identification information, the locking of the door or its unlocking with the release of the catch is executed or canceled by controlling the electric lock. The operating reliability of the system is greatly increased with simple handling due to the fact that the door handle can be swivelled up and down about a horizontal swiveling axis in a handle recess in the door, and it can be reset automatically into the starting center position again by spring elements after the door handle is released, and electric switches can be actuated in the switch positions of the door handle, initiating the identification and the locking procedure as well as the identification and the unlocking procedure.
摘要:
A motor vehicle door lock system including a vehicle lock adapted to be locked and unlocked, a lock element adapted to be moved between a locked position and an unlocked position for locking and unlocking respectively the vehicle lock, a central interlock drive having a slow running drive element for moving the lock element, a remote control module, control electronics with a passive entry function to at least passively unlock the vehicle lock, and a high-speed electromagnetic drive for rapidly moving the lock element from the locked position to the unlocked position to thereby unlock the vehicle lock quicker than by operating the drive element. The passive unlocking of the vehicle lock occurs over time requiring a reaction phase with a starting interval, an authorization check interval, and an action interval, the starting interval being initiated by an operator. The high-speed electromagnetic drive is immediately activated at start of the action interval, and subsequent to the activation, the central interlock drive is operated to move the slow running drive element to a position corresponding to the unlocked position of the lock element.

A motor veicle compartment closure lock with a locking wedge (2) attached on the closure, and lock elements attached on an opening frame for the closure. The locking wedge (2) can be retracted, in a powered way, from an extended, open position into a pushed-in, locked position and, for this purpose, is coupled by a lever mechanism (3) to a power transmission element (5) with a powered drive. The powered drive can be built especially small and light because the drive is made as a drive that operates only in one direction (locking direction) and returns automatically in the opposite direction. Power transmission element (5) is slaved or can be slaved to the locking wedge (2) in the locking direction and moves freely in the opposite direction. A shifting lever (6) is provided that is carried by the power transmission element (5) in the locking direction and is spring-loaded in the opposite direction. The shifting lever has an engaging part (7) that moves in a shifting link (8), and the engaging part (7) can be brought by a movement in the locking direction, from an open rest stop (9), to lie against a locking stop (10) and can be brought, by renewed movement in the locking direction, from the locking stop (10) back again to the open rest stop (9).
摘要:
A motor vehicle door lock system with a vehicle lock, which can be locked and unlocked by a motor, includes a lock element which can be moved between a locked position and an unlocked position, and a central interlock drive with a slow-running drive element with which the lock element can be moved, with control electronics with a passive entry function, a speed unlocking element and a remote control module for the operator. The motor vehicle door lock system includes a clutch which engages only with a minimum rpm, which ensures that the lock element can be easily moved by hand with the central interlock drive stationary. The speed unlocking element is assigned to the central interlock drive on this side of the clutch and can be immediately actuated by the central interlock drive upon starting. The speed unlocking element immediately moves the lock element or an element of the lock mechanism downstream of it, the central interlock drive follows up, with the clutch engaged, more slowly into the unlocked position or via the unlocked position in to the next rest position when actuated out of the locked position into the unlocked position.

The subject matter of the invention is a motor vehicle closing device with a positioning element (3) which turns around one axis of rotation (7) or which moves linearly along one lengthwise axis and which has a position which is to be ascertained, and with a position detection means (8) which works without contact and which is located on the path of motion of the positioning element (3) (or on the positioning element 3 itself). It thus lends itself to “diagnosis” by the fact that on the positioning element (3) (or on the path of movement of the positioning element 3) in the direction of its motion there are several passive position detection elements (9) in succession and that position detection takes place by counting the signals of the position detection elements (9) by the position detection means (8). In particular it is provided that the position detection means (8) has a sensor which is sensitive to magnetic fields, especially a Hall sensor, a reed contact or a magnetoresistive sensor and the position detection elements (9) are made as alternatingly magnetic and nomnagnetic pole zones or pole zones which are magnetized with changing polarity.

A motor vehicle door lock or the like has a housing (1) or a lock bearing plate, a rotary latch (2) with a jaw (3) for a locking wedge (4) or lock bolt and a pawl (7) for locking the rotary latch (2) in a locking position which corresponds to the closed motor vehicle door. Several complementary measures are proposed which can be applied together or separately to optimise the locking elements—rotary latch (2) and pawl (7). A differentiated positioning of the rotary latch (2) and pawl (7) is particularly significant. The material, shape and/or mounting of the swivelling axis (10) of the rotary latch (2) or of the swivelling axis (20) of the pawl (7) are designed for normal operation conditions. However, in the event of tearing up forces which are considerably higher than the normal operation conditions (crash), the rotary latch (2) or pawl (7) can be displaced in such a way that a substantial proportion of the tearing up forces can be absorbed by the supporting area of a recess (11) which contains the rotary latch (2) or of a recess (21) which contains the pawl (7).
摘要:
A motor vehicle door lock arrangement with a lock latch, a detent pawl and an electrical detent pawl drive with control switches for a triggering detent pawl drive, a power supply connection and a lock mechanism with at least one mechanical opening lever which acts on the detent pawl. In the normal case, the detent pawl can be actuated only by the electrical detent pawl drive (1), and in an emergency, by the mechanical opening lever (2). The motor vehicle door lock arrangement provides the electrical detent pawl drive (1) with a mechanical energy storage device (15) which is tensioned in the rest position of the detent pawl drive (1) and which keeps the opening lever (2) prepared for mechanical activation should the power supply fail or some other malfunction of electrical detent pawl drive occur.
