A vehicle audio system that includes a source of audio signals, which may include both entertainment audio signals and announcement audio signals, speakers for radiating audio signals, and spatial enhancement circuitry comprising circuitry to avoid applying spatial enhancement processing to the announcement audio signals.

Manipulating spatial processing in an audio system

An RF receiver operates to receive broadcast RF signals that include at least one of an analog portion and a digital portion. The RF receiver performs processing of the analog portion and/or the digital portion to generate a digital path signal. The RF receiver performs further processing of the analog portion to generate a first audio signal. A digital modulation processing system may be electrically connected with the RF receiver. The digital modulation processing system may receive and process the digital path signal to generate a second audio signal. The RF receiver may selectively utilize at least one of the first audio signal and the second audio signal to generate an audio output.

AM/FM/IBOC receiver architecture

A vehicle radio receiver has a beamsteering control system with two signal paths. One signal path generates an audio signal in response to incoming radio signals. Another signal path generates a test signal in response to the incoming radio signals. The audio signal is adjusted in response to the test signal.

Beamsteering control system for a vehicle radio receiver

A method of controlling an antenna signal combiner in a vehicle having a navigational system, a broadcast receiver, and multiple antenna elements. The method comprises the steps of the broadcast receiver receiving broadcast signals from a broadcast tower. Then, determine first position coordinates of the vehicle using the navigation system. Next, determine second position coordinates of the broadcast tower and then combining signals from the multiple antennas to steer an antenna beam from the first position coordinates towards the second position coordinates. This method allows for accurate and timely tracking of a broadcast signal.

Antenna beam steering responsive to receiver and broadcast tower coordinates

A method of controlling an antenna signal combiner in a vehicle having multiple antenna elements. The method comprises the steps of receiving broadcast signals from the antenna elements. An antenna beam is steered toward a first steering angle. Navigation data is generated in response to a navigation sensor, the navigation data identifying a relative changes in vehicle direction. The antenna beam is steered toward a second steering angle in response to the relative change in vehicle direction.
