The invention relates to a method () for a security system () of a vehicle (), in particular for a keyless activation of at least one security function of the vehicle ().

Method for activation of at least one security function of a security system of a vehicle

The invention relates to a method () for an activation of at least one security function of a security system () of a vehicle (), wherein an authentication at the security system () of the vehicle () is effected by means of a mobile identification transmitter ().

Method for activating at least one security function of a security system of a vehicle

The invention relates to a method () for activating at least one security function of a security system () of a vehicle (). According to the invention, provision is made for the detection of at least one distance information about a distance (A) of a mobile identification transmitter () to the vehicle () by means of a detection device () of the vehicle () and a transmission of the distance information by a data transmission from the detection device () via a transmission system () of the vehicle () to a processing device () of the vehicle (), wherein the data transmission of the distance information is performed in a forgery-proof manner.

Method for activating of at least one security function of a security system of a vehicle

A remote key fob for a vehicle, includes a communications and control device, at least one transmit/receive device and a microcontroller. At least one control surface is arranged on an outer shell of a housing of the remote key fob and is coupled to the communications and control device. A printed circuit board held in the housing is placed beneath the control surface. The control surface is mechanically coupled to a metal detection section. Pressure actuation of the control surface from the outside results in a deformation or change of position of the detection section. A detection coil is located on the printed circuit board, wherein the detection coil is coupled to the communications and control device for forming an inductive proximity switch. The communications and control device determines an actuation of the control surface as a function of the inductivity or quality of the detection coil.

Remote key fob for motor vehicles

A radio key for an access system of a motor vehicle includes a receiver circuit with at least three LF receiver coils for reception of a low frequency signal. The receiver coils are oriented in different spatial directions. A central control circuit includes a microcontroller coupled to the receiver circuit. The control circuit with the microcontroller can assume an energy-reduced resting state and an active operating state. The receiver circuit is configured to awaken the control circuit from the resting state when a signal is received by the LF receiver coils. The central control circuit is configured to activate each of the LF receiver coils separately and to query a received signal strength. The central control circuit then selects the LF receiver coil with the highest signal strength for a subsequent signal reception.

Vehicle key for passive access systems and corresponding method

An ID transmitter for a motor vehicle access system includes a printed circuit board which is enclosed by a plastic housing. An antenna subassembly arranged next to the printed circuit board is connected thereto and includes a carrier film carrying conductor tracks. The components include a power supply cell, an LF 3D coil assembly, and HF transceiver components, an NFC module and at least one controller component. The conductor tracks of the carrier film form an NFC antenna coil which is coupled to the NFC modules via the conductors of the printed circuit board. The carrier film is arranged substantially in a plane parallel to the printed circuit board and protrudes over the edge of the printed circuit board on all sides. The conductor tracks forming the NFC antenna coil are arranged primarily in the edge region of the carrier film protruding over the edge of the printed circuit board.

Compact ID transmitter comprising an NFC communications option for a motor vehicle access system

A portable identification transmitter for a passive access system of a motor vehicle includes an electrical buffer store which is coupled to an LF circuit assembly in order to charge the electrical buffer store via an energy draw from electromagnetic fields coupled in via LF antennas. Also included is an electronic switching device which can decouple a battery from a microcontroller of the passive access system. The microcontroller and the LF circuit assembly are coupled to the buffer store so that when the buffer store is charged beyond a specified charging level, the open electronic switching device can be activated to couple the battery to the microcomputer via the microcontroller while energy is supplied to the microcontroller from the buffer store.
