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 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.
