Abstract:
1. A method of near real-time band jamming prevention, comprising the steps of: measuring by a vehicle controller the received signal strength intensities of at least two samples of a first communication band and at least two samples of a second communication band; determining by the vehicle controller if a difference of the received signal strength intensities between each of said samples of the first communication band and the second communication band is greater than a first reference value; determining by the vehicle controller an average value of said samples of the received signal strength intensities between the first communication band and the second communication band; wherein if the resulting value of the average value of the received signal strength intensities between the first communication band and the second communication band subtracted from a second reference value is determined to be greater than a first criterion, then the vehicle controller switches the first communication band to another communication band; if the resulting value of the average value of the received signal strength intensities between the first communication band and the second communication band subtracted by the second reference value is determined to be smaller than a second criterion, then the vehicle controller switches the first communication band to another communication band.
