  • Patent number: 11963011
    Abstract: A strength meter in a relay attack determination device is disposed on a portable device and measures a reception strength by a plurality of times in each of a request signal and a request signal received from an in-vehicle device. A comparator executes a comparative process of the request signal and the request signal by using average values of the reception strength measured by the strength meter. A variation calculator calculates variation in the reception strength measured by a plurality of times in the strength meter regarding the request signal. The comparator, in a case where the variation in the reception strength exceeds a threshold value indicating a communication failure in the request signal, determines the relay attack regardless of a result of the comparative process.

  • Patent number: 11702035
    Abstract: A portable device includes a reception antenna and a strength meter. The reception antenna includes antennas of three axes each receiving a first signal and a second signal. The strength meter measures a reception strength of the request signal and the request signal received by each of the three axes of the LF receiver. A relay attack determination device is provided with a comparator that executes a comparative process of strength ratios of the request signal and the request signal based upon a measurement value of the reception strength. In a case where the three axes include an ineffective axis, in which the measurement value of the reception strength of the request signal or the request signal deviates from a usable range, the comparator excludes the ineffective axis and executes the comparative process.
