Embodiment Construction

[0016] figure 1 An exemplary system 100 for detecting and reporting the occurrence of radio frequency (RF) interference in a vehicle 105 is shown. Vehicle 105 may be any type of vehicle, such as a car, truck, bus, airplane, helicopter, or boat. System 100 may take many different forms and may include various and / or alternative components. although figure 1 An exemplary system 100 is shown, and the exemplary components described in system 100 are not meant to be limiting. Indeed, additional or alternative components and / or implementations may be employed.

[0017] System 100 can detect the presence of RF interference and take action against would-be thieves, as well as log, mitigate, and alert the occurrence of interference. RF interference can be caused by intentional jamming of vehicular RF communications equipment (eg, by thieves using special transmitters), or it can be unintentional by radio towers or military bases. For example, a 105MHz radio tower could inadvertent...

Abstract

A vehicle system for detecting an interfering signal includes a receiver configured to receive a signal having a signal characteristic. A controller may be in communication with a receiver configured to determine a jamming event probability based at least in part on the signal characteristic.

Description

technical field [0001] The invention relates to the technical field of vehicle communication, in particular to a vehicle radio frequency interference detection and mitigation system and a method for applying the system. Background technique [0002] Vehicles are equipped with various types of communication devices that are used to perform and facilitate various functions. In particular, radio frequency (RF) is often employed to communicate between devices. For example, remote keyless entry (RKE) systems employ RF communications, which allow a person to remotely lock or unlock the doors of a vehicle. When a button of the fob or keyfob is pressed, the fob transmits an encoded signal to a receiving unit within the vehicle. The remote entry controller locks or unlocks the doors of the vehicle when a valid RF signal is delivered to the receiving unit. [0003] However, there is still the possibility that alien RF pulses interfere with the RF transmission and reception of the s...
