Abstract
The present disclosure relates to a head unit for an infotainment system of a vehicle. The head unit is coupled to a mobile terminal device via a Bluetooth link. The head unit is configured to exchange a digital audio signal adapted for improved audio quality during the hands-free talking, via an additional wireless link, in response to hands-free talking during a phone call with the mobile terminal device coupled via the Bluetooth link based on a hands-free profile.
Claims17
A head unit for an infotainment system of a vehicle, wherein the head unit is coupled to a mobile terminal device via a Bluetooth link for control purposes, the head unit being configured to:
- in response to hands-free talking during a phone call with the mobile terminal device coupled via the Bluetooth link based on a hands-free profile, exchange, at an audio signal processing module of the vehicle, a digital audio signal adapted for improved audio quality during the hands-free talking, via an additional wireless link, and
- based on the mobile terminal device, surrounding information of the mobile terminal device, a vehicle type, or vehicle speed, selecting, by the audio signal processing module of the vehicle, an audio codec, a maximum value of bandwidth for the phone call, and a sampling frequency of the digital audio signal for the phone call.
A system comprising:
- a mobile terminal device;
- and
- a head unit for an infotainment system of a vehicle, wherein the head unit is configured to:
- in response to hands-free talking during a phone call with the mobile terminal device coupled via a Bluetooth link for control purposes based on a hands-free profile, exchange, at an audio signal processing module of the vehicle, a digital audio signal adapted for improved audio quality during the hands-free talking, via an additional wireless link, and
- based on the mobile terminal device, surrounding information of the mobile terminal device, a vehicle type, or vehicle speed, select, by the audio signal processing module of the vehicle, an audio codec, a maximum value of bandwidth for the phone call, and a sampling frequency of the digital audio signal for the phone call.
A method for exchanging a digital audio signal between a mobile terminal device and a head unit of an infotainment system of a vehicle, the method comprising:
- coupling the mobile terminal device and the head unit via a Bluetooth link for control purposes based on a hands-free profile;
- exchanging, at an audio signal processing module of the vehicle, a digital audio signal adapted for improved audio quality during hands-free talking via an additional wireless link in response to the hands-free talking during a phone call with the mobile terminal device using the Bluetooth link, and
- based on the mobile terminal device, surrounding information of the mobile terminal device, a vehicle type, or vehicle speed, selecting, by the audio signal processing module of the vehicle, an audio codec, a maximum value of bandwidth for the phone call, and a sampling frequency of the digital audio signal for the phone call.
