Abstract

A system for preventing a relay attack on a vehicle is provided. The system includes a base unit positioned in the vehicle and operably connected to at least one vehicle system. The base unit is configured to obtain position information of the base unit. The system further includes a portable operating unit configured to obtain and transmit position information of the portable operating unit to the base unit. The base unit determines the position of the portable operating unit relative to the base unit and selectively controls operation of the at least one vehicle system based on the determination of the position of the portable operating system relative to the base unit.

Description

technical field [0001] The present invention relates to a system for preventing relay attacks on a vehicle having a system operable based on the proximity of an authorized user relative to the vehicle. Background technique [0002] Conventional proximity-based vehicle systems allow authorized users (ie, users holding authorized fobs) to operate the vehicle system when the authorized user is within a predetermined distance from the vehicle. One example of a proximity based vehicle system is a key fob system. In the smart key system, a user with an authorized fob can actuate the door lock of the vehicle without mechanically inserting the key into the lock cylinder. In a smart key system, a user can actuate a switch on the outside of the vehicle. The switch may be actuated by, for example, operating a door handle or a button on the outside of the vehicle. [0003] In response to operation of the switch, the vehicle transmits a low frequency (LF) signal. The LF signal is typ...
