1. A method of operating a vehicle, comprising the steps of:
- receiving a radio frequency signal;
performing an autocorrelation operation on data sampled from the radio frequency signal;
determining that the radio frequency signal has at least one characteristic indicative of the vehicle entering a tunnel, the determining step being dependent upon a result of the autocorrelation operation; and
automatically modifying a setting of a vehicle system in response to the determining step.

Abstract
A method of operating a vehicle includes receiving a radio frequency signal and determining that the radio frequency signal has at least one characteristic indicative of the vehicle entering a tunnel. A setting of a vehicle system is automatically modified in response to the determining step.

8. A method of operating a vehicle, comprising the steps of:
-
storing a group of vehicle system settings, the group of settings being preferred when the vehicle is in a tunnel; receiving a radio frequency signal; determining that the radio frequency signal has a decrease in field strength that is indicative of the vehicle entering a tunnel; and automatically implementing at least one of the preferred vehicle system settings in response to the determining step. - View Dependent Claims (9, 10, 11, 12, 13, 14)

15. A method of operating a vehicle, comprising the steps of:
-
receiving a broadcast radio frequency signal; determining that the broadcast radio frequency signal has at least one first characteristic indicative of the vehicle entering a tunnel, the first characteristic comprising a decrease in field strength and/or an autocorrelation value that is greater than a threshold value; automatically changing a setting of a vehicle system from a first state to a second state in response to the determining step; ascertaining that the broadcast radio frequency signal has at least one characteristic indicative of the vehicle exiting the tunnel, the ascertaining step occurring after the automatically modifying step; and automatically changing the setting of the vehicle system back to the first state in response to the ascertaining step. - View Dependent Claims (16, 17, 18, 19, 20)
