Embodiment Construction

[0040] exist figure 1 Vehicle 1 is shown in . Vehicle 1 communicates with an external communication device 3 via a communication link. To this end, the first communication device 7 is connected via a Bluetooth connection 9 to a hands-free communication device 11 of the vehicle 1 .

[0041] The hands-free communication device 11 detects the voice spoken by the user of the vehicle 1 by means of a microphone and transmits a corresponding voice signal via the Bluetooth connection 9 to the first communication device 7, which then transmits the voice signal to the external communication device 3 Transmit or receive voice signals (as indicated by arrow 5 ) from external communication device 3 and transmit them to hands-free communication device 11 via Bluetooth connection 9 .

[0042] The communication device 7 is configured by default to process the incoming or outgoing speech signals in such a way that the speech signals can be reproduced on the communication device with optimum ...

Abstract

An embodiment relates to a computing device for determining a signal quality of a communications connection, wherein the computing device is configured to receive a first signal of a test sequence of a first communications device and a second signal of a test sequence of a second communications device connected to the first communications device and comprised in a vehicle, and wherein the computing device is configured to determine at least one signal quality parameter of the first signal and of the second signal, respectively, and to determine settings and / or signal processing methods for a hands-free device of the vehicle on the basis of a comparison of at least one signal quality parameter of the respective first and second signals, whereby a signal quality of a signal to be transmitted by the first communications device to an external communications device is improved.

Description

technical field [0001] The invention relates to a method for adjusting the speech quality of a communication connection between a first communication device coupled to a vehicle and a second external communication device. The invention also relates to a computing unit configured to implement the proposed method. Background technique [0002] When using a communication device coupled to the vehicle, for example via a Bluetooth connection, there is a quality impairment in the voice quality of eg connections to external communication devices connected to the vehicle due to the settings of the communication device optimized for unlinked communication. [0003] European publication EP 203 18 46 A1 discloses a method for calibrating a hands-free system in a motor vehicle, in which a test signal to be generated by the hands-free system is compared with a specified signal. [0004] European publication EP 188 32 13 A1 discloses a method for calibrating a hands-free system, in which...
