摘要:
A locking system for providing authorization to access and drive a motor vehicle has a first control device for unlocking and locking the car doors, the ignition lock, the steering wheel lock, etc. Additionally, the locking system has a second device, which is an electronic key or an identifier. The two devices have transmission means and/or receiving means for electromagnetic signals with frequencies ν lying in a frequency band between two cut-off frequencies νa, νb. At least one of the signals, transmitted between the devices, is a coded operating signal for authenticating the second device. The actual frequency νi with which the transmission means of the second device is operated is stored in a storage means of the first device.
摘要:
A system for automatic access or driving authorization for a motor vehicle includes a first device in the form of a control device having at least two states for engaging and disengaging vehicle door locks, an immobilizer, or the like. An associated second device is provided in the form of an electronic key, an ID transmitter, a chip card or the like. Both devices have means for transmitting or receiving signals, including a coded operating signal for authenticating the second device, so that a change in the state of the first device can be implemented when the second device is authorized. Before the second device is first activated, it is in a sleep state in which operation-independent function is not permitted and energy consumption is reduced. During a first operator-dependent authentication, the second device is changed over from the sleep state into a standby state in which an operation-independent function is at least partially made possible.

The invention relates to a vehicle security system in the form of a keyless-go system and an operating method for it. In the vehicle security system, incorrect detection of a position of an authentication element (1) inside or outside the vehicle by authentication element locating means (21) in a vehicle-mounted access control component owing to at least one interference transmitter (10) which is present in the surroundings of the vehicle and/or of the authentication element (1) is avoided by using a device for performing empty measurement (9) in the authentication element (1). To do this, the device for performing empty measurement (9) performs a measurement in time periods in which the vehicle-mounted access control component (2) does not emit any pulses to the authentication element (1), by means of which measurement the interference level caused by the at least one interference transmitter (10) is determined. Depending on whether this determined interference level exceeds or drops below a predetermined threshold value, either the device for performing empty measurement (9) transmits, to the vehicle-mounted access control component (2), an adapted threshold value for a decision as to whether an authentication element (1) is located in the vehicle or outside the vehicle, or said device does not respond to subsequent pulses from the vehicle-mounted access control component (2).
摘要:
An electronic closure system has one or more lockable and unlockable closure units, each arranged on an opening element of an object to be secured, at least one authorizing authentication element and a closure control unit with at least one authentication element identification sensor. The at least one authentication element identification sensor has a predetermined detection area, which covers an external detection zone outside the object. The closure control unit produces different closure control commands, related to locking and/or unlocking, based on whether and in what external detection zone authorizing authentication element is detected. The closure control unit contains a sensor system for determining the range of an identified authentication element from the object and, on identification of an authorizing authentication element, automatically produces different closure control commands for the respective closure unit, as a function of the range between the identified authentication element and the object.
摘要:
An electronic safety system, particularly a vehicle locking system, has several safety units arranged on an object to be secured, at least one authorizing authentication element, and safety control devices with several object-side authentication element detection sensors. Signal sending devices emit a query data signal in a pertaining acquisition range, which can be received by an authentication element situated in the corresponding acquisition range. The authentication element has devices for returning an authentication response signal. According to the invention, the query data signals emitted by the detection sensors contain a sensor-specifically coded data protocol range, and the authentication element has devices for analyzing the sensor-specifically coded data protocol range of received query data signals and for generating an authentication response signal which contains a sensor-indicative data protocol range which is coded with the information as to from which detection sensors the authentication element has received a query data signal.

A handle arrangement for a vehicle door with a door handle mounted on its outside and a capacitive locking sensor arranged in the region of the door handle which is remote from the door has a capacitive sensor for a convenience closing function additionally provided in the region of the door handle which is remote from the door. These measures provide a user with a convenient and safe way of locking the vehicle and closing all vehicle openings.

An electronic starter and steering locking device for a motor vehicle has a steering locking unit including a locking control unit that operates an actuating unit for locking and unlocking a vehicle steering element; a vehicle starter unit for starting and shutting off the motor vehicle; and a voltage supply. The locking control unit is permanently connected to the voltage supply independently of the driving state of the vehicle, while the locking actuating unit is connected to the voltage supply via interrupter switching means which can be switched over as a function of the operating state of the vehicle starter unit and/or of the switched position of a drive train transmission shift lever.
摘要:
A door handle is mounted on the outside of a vehicle door in a deflectable fashion, and a sensor for detecting a manual deflection of the door handle relative to the vehicle door is arranged in the door handle. It is possible to trigger a vehicle function electrically with the door handle when a predefined deflection value for the door handle is reached. These measures make access to a vehicle comfortable and reliable.
