Problems solved by technology

[0015] The problem with all these prior art arrangements is that they cannot determine if the fob is in motion when entering an LF field near the vehicle, nor can they detect any complex movement of the fob

Embodiment Construction

[0031] figure 1 A schematic diagram illustrating a vehicle PEPS system 100 is shown in . The PEPS system 100 allows the vehicle owner (or fob owner) to lock / unlock and start the vehicle 105 without having to interact with the fob 110 . A typical PEPS system defines an external entry operating area and an internal initiation operating area. If the key fob 110 is within the operating area, the vehicle 105 will respond to lock / unlock and start requests.

[0032] The PEPS operating region may be defined by a low frequency (LF) signal magnetic field transmitted from an antenna on the vehicle. A Received Signal Strength Indicator (RSSI) may be used in the key fob, and the PEPS system may use RSSI signal levels measured from various antennas on the vehicle 105 to define the outer and inner operating zones. The vehicle 105 will then respond to lock / unlock and start requests if the key fob 110 is within the correct zone (ie, the RSSI level corresponds to the defined operating zone)....

Abstract

A method and system for detecting if a relay is present in a PEPS system for a vehicle is provided by (a) determining whether movement of an authentication device was detected within a predefined timeperiod after the authentication device enters a PEPS entry operational region; and (b) determining if the authentication device was stationary for a predetermined time period during a PEPS entry triggering event.

Description

technical field [0001] The present invention relates to keyless entry and start (PEPS) systems, and more particularly to the detection and / or prevention of relay attacks on PEPS systems in vehicles for entering and / or starting the vehicle. Background technique [0002] The PEPS system allows authorized users (with valid key fobs) to lock / unlock and start their vehicles without having to interact with the remote control (ie, authorized key fobs). If it is determined that the key is stuck in a valid PEPS zone, the PEPS system can unlock or start the vehicle through a manually triggered entry request (capacitive sensor, button, etc.). [0003] A typical PEPS system defines areas of operation such that if an authorized key fob is within the correct area of ​​operation, the vehicle will respond to lock / unlock and start requests. A PEPS region may be defined by a low frequency (LF) signal field emitted from an antenna on the vehicle. Received Signal Strength Indication (RSSI) is...
