A tunnel detection system for a motor vehicle comprises a radiofrequency signal receiver provided to receive a radiofrequency signal coming from a source external to the vehicle; a controller communicating with the radiofrequency signal receiver, the controller being configured to detect at least one amplitude variation in the radiofrequency signal received by the receiver; the controller is configured to determine at least one correspondence level representative of the difference between the detected amplitude variation in the radiofrequency signal and at least one predetermined reference signal amplitude variation representative of the amplitude variation in a signal received by the receiver when the receiver travels into a tunnel; the controller is configured to compare the determined correspondence level with a predetermined minimum correspondence threshold, and detect the tunnel being travelled through by the detection system when the determined correspondence level is greater than or equal to the predetermined minimum correspondence threshold.
