摘要
A method for controlling a communication system (1) embedded in a vehicle comprising an antenna (2), a receiving unit (4) comprising two tuners (42, 43) and an output unit (3), the antenna (2) having a sensitivity pattern depending on the direction from which the signal is received by the antenna (2). Each tuner (42, 43) comprises a power saving mode in which the tuner is in standby, a scanning mode in which the tuner scans the frequency band to update the frequency on which to start, and a main mode in which the tuner is used by the receiver unit (4) to transmit the signal, and the embedded communication system (1) further comprises a power consumption unit (5) receiving the vehicle position, a broadcast transmitter database and said antenna sensitivity pattern. The method comprises different steps in which the tuners are switched between there three operating modes depending on the orientation of the vehicle and the sensitivity pattern.
