Abstract:
A method for assessing a reliability of a determination of the relative position between a device for accessing a vehicle and the vehicle including transmitting a first radio signal from a first antenna of the vehicle; transmitting a second radio signal from a second antenna of the vehicle; receiving the first radio signal at the device and determining a first signal intensity; receiving the second radio signal at the device and determining a second signal intensity; determining, at the device or the vehicle, a relative position of the device and/or the vehicle and/or signal directions from which the radio signals have arrived at the device, based on the first signal intensity and the second signal intensity; determining a compatibility of the determined relative position and/or the signal directions with an arrangement of the first antenna and the second antenna at the vehicle to assess the reliability of relative position determination.
