, Description:TECHNICAL FIELD

Present disclosure generally relates to the field of automobiles. Particularly but not exclusively, the present disclosure relates to an audio system equipped in a vehicle. Further, embodiments of the present disclosure disclose a method and system for controlling output from the audio system installed within a cabin of the vehicle.

BACKGROUND OF THE INVENTION

Vehicles are generally equipped with In-car entertainment [ICE] systems, which may include audio, visual or other entertainment systems. The audio system that are equipped in vehicles enhance the comfort and convenience of the user. Audio system may be operated in a media mode or in a communication mode. In media mode, it enables user to listen to music while operating the vehicle, whereas in the communication mode it allows user to receive and make calls. To facilitate such communication, the audio system in the vehicle may be communicatively coupled to a user device such as smart gadget of the user. Further, music may be received from various sources and may correspond to various genres. For example, user may listen to music being streamed from a radio station or may select music from a playlist. The user may also initiate a phone call or receive an incoming phone call through the smartphone and the audio system in the vehicle. The audio system in the vehicle may also include multiple microphones to pick up the sounds within the cabin of the vehicle and the microphone may enable the user to have a conversation through the phone call.

Generally, volume or the output from the audio system is often pre-set by the user. Further, when passengers in the cabin of the vehicle initiate a conversation with the driver or with co-passengers, the driver or intended receiver is often unable to listen to the conversation when the volume output from the audio system is high-pitched. The driver has to often reach out to the volume knobs or switches to reduce the volume output from the audio system so that the conversation from other passengers in the cabin becomes audible. Further, when the operational state of the audio system is in the communication mode, i.e., when a phone call is received or initiated by user, ambient noise may sometimes reduce the ability of the user to listen and interpret the phone call. The ambient noise may include the noise from the surroundings of the vehicle and the noise from the conversations among the passengers in the cabin of the vehicle. In some scenarios, when the ambient noise is high-pitched, the phone call may become inaudible and the user may have to reach out to the volume control knobs for increasing the volume output of the audio system in order to attenuate the ambient noise. The above-mentioned scenarios often provoke the user to manually adjust the output from the audio system in accordance with their convenience. Further, the above-mentioned scenarios, which require manual intervention from the user, often distract the user from operating the vehicle. These distractions in some scenarios may be fatal and may lead to accidents.

The present disclosure is directed to overcome one or more limitations stated above, or any other limitation associated with the prior arts.

It is to be expressly understood, however, that each of the figures is provided for the purpose of illustration and description only and is not intended as a definition of the limits of the present disclosure.

In the present document, the word "exemplary" is used herein to mean "serving as an example, instance, or illustration." Any embodiment or implementation of the present subject matter described herein as "exemplary" is not necessarily to be construed as preferred or advantageous over other embodiments.

While the disclosure is susceptible to various modifications and alternative forms, specific embodiments thereof have been shown by way of example in the drawings and will be described below. It should be understood, however that it is not intended to limit the disclosure to the particular forms disclosed, but on the contrary, the disclosure is to cover all modifications, equivalents, and alternative falling within the scope of the disclosure.

The terms “comprises”, “comprising”, or any other variations thereof, are intended to cover a non-exclusive inclusions, such that a system that comprises a list of components does not include only those components but may include other components not expressly listed or inherent to such mechanism. In other words, one or more elements in the device or mechanism proceeded by “comprises… a” does not, without more constraints, preclude the existence of other elements or additional elements in the mechanism.

Embodiments of the present disclosure discloses a method for controlling output of an infotainment system in a vehicle. In the conventional systems, user has to manually adjust the output from the infotainment system when an ambient noise was excessive or high-pitched within a cabin of the vehicle. The ambient noise would sometimes attenuate conversation of the rear seat passengers or during a call. Consequently, the user has to manually adjust the output from the infotainment system according to their convenience. Manual intervention from the user often distracts the user from operating the vehicle. These distractions in some scenarios may be fatal and may lead to accidents.

Accordingly, the present disclosure discloses a method for controlling output from an infotainment system in a vehicle. The method includes steps of detecting an operational state of the infotainment system by a control unit associated with the infotainment system. When the operational state of the infotainment system is detected in an ON condition, the control unit monitors an ambient noise within the cabin of the vehicle and the sound output from the infotainment system. The process of monitoring the ambient noise in the cabin of the vehicle by the control unit includes steps of continuously receiving the ambient noise inside the cabin of the vehicle through one or more microphones positioned in the cabin of the vehicle. Based on the ambient noise received from one or more microphone, the control unit determines level of the ambient noise in the cabin of the vehicle. The method also involve the aspect of comparing the level of the ambient noise with a pre-determined threshold level. When the ambient noise is determined to be greater than the threshold limit, the control unit modulates the output of the infotainment system. In some embodiments, the control unit modulates the output from the infotainment system by decreasing the output from the infotainment system when the functional state of the infotainment system is the media mode. The control unit also modulates the infotainment system by increasing the output from the infotainment system when the functional state of the infotainment system is the communication mode.

The following paragraphs describe the present disclosure with reference to Figs. 1 to 3.

Fig. 1 illustrates a block diagram of a system (200) for controlling an infotainment system (203) in a vehicle. Fig. 2 shows a detailed block diagram of components of the system (200) for controlling the infotainment system (203) in the vehicle. The infotainment system (203) may include plurality of audio systems or speakers (203b) [herein referred to as speakers]. The speakers (203b) may be coupled with but not limited to radio, compact disc player, MP3 player, MP4 player etc. The user may selectively operate any one of the devices coupled to the speakers (203c) through an I/O interface (203a) of the infotainment system (203). The I/O interface (203a) may be a communication module and may include hardware elements including a touch screen control panel, knobs, switches, various control dials, buttons etc. The hardware components of the I/O interface (203a) may form a unitary unit. The unit may be installed in an instrument panel of the vehicle. The unit may be fixedly or removably attached in the instrument panel. In an embodiment, the hardware elements may be installed in multiple locations of the vehicle including but not limited to the steering wheel, arm rests in the passenger seats etc. The user may control volume from speakers (203b) through the I/O interface (203a). The user may also control the distribution of sound among the individual speakers of the vehicle. In an embodiment, the I/O interface (203a) of the infotainment system (203) may be communicatively coupled to a user device including but not limiting to smartphone, smart watch, and other external devices of the user. These user devices may be communicatively coupled to the I/O interface (203a) of the vehicle by wired or wireless connections, including but not limited to Bluetooth, AUX cables, USB ports, SD card readers etc.

The infotainment system (203) may be operable between a media mode (103a) and a communication mode (103b). The user may adjust a radio station, a playlist, a source of audio input, through the I/O interface (203a) when an operational state of the infotainment system (203) is in the media mode (103a). Further, the communication mode (103b) of the infotainment system (203) may include but not be limited to the aspect of operating the speakers (203b) of the vehicle as a substitute to the speakers (203b) of the user device of the user. The user may initiate or receive incoming calls through the infotainment system (203) of the vehicle when the infotainment system (203) is operated in the communication mode (103b). The cabin of the vehicle may include a plurality of microphones (201) for facilitating the calls that are initiated or received from the user. The plurality of microphones (201) may be included to receive user input in the form of voice commands and to enable the user to conduct telephone calls. The microphone (201) may also be used to measure ambient noise in the cabin of the vehicle. The microphones (201) may be mounted at multiple locations in the vehicle including but not limited to the roof, the dashboard, the instrument cluster etc.

The system (200) also includes a control unit (202) that receives the inputs from the microphone (201) and is communicatively coupled to the infotainment system (203). The control unit (202) may include a receiving module (202a), a processing module (202b), a comparison module (202c) and a regulating module (204d). The receiving module (202a) receives the ambient noises picked up by the microphones (203) placed inside the cabin of the vehicle. Further, the processing module (202b) of the control unit (202) may process the ambient noise from the microphone (201). The processing module (202b) may quantify or measure the level of the ambient noise received by the microphones (203). In an embodiment, the processing module (202b) may quantify the level of the ambient noise by any known method in the art. In an embodiment, the processing module (202b) may quantify the level of the ambient noise in decibels. The control unit (202) including the comparison module (202c) may compare the level of the ambient noise from the microphone (201) with a pre-determined threshold level. The pre-determined threshold level may range from 68 db to 72 db. In an embodiment, the pre-determined threshold level may be selected or set by the user through the I/O interface (203a) of the infotainment system (203). The regulating module (202d) of the control unit (202) may regulate or modulate the output of the speakers (203b) in the infotainment system (203) based on the results from the comparison module (202c).

Fig. 3 is a flowchart for illustrating method steps for controlling the infotainment system (203) in the vehicle. As illustrated in Fig. 3, the method comprises one or more blocks illustrating a method for controlling the infotainment system (203) in the vehicle. The method may be described in the general context of computer-executable instructions. Generally, computer-executable instructions can include routines, programs, objects, components, data structures, procedures, modules, and functions, which perform functions or implement abstract data types. The order in which the method is described is not intended to be construed as a limitation, and any number of the described method blocks can be combined in any order to implement the method. Additionally, individual blocks may be deleted from the methods without departing from the spirit and scope of the subject matter described herein. Furthermore, the method can be implemented in any suitable hardware, software, firmware, or combination thereof.

The first step (101) involves the aspect of determining the operational state of the infotainment system (203). The operational state of the infotainment system (203) may be determined by any known methods or system in the art. The control unit may interpret the operational state of the infotainment system (203) as an ON condition when signals corresponding to the operational state of the vehicle is received by the control unit (202). Further, the above-mentioned method for the control unit (202) to concur that the operational state of the infotainment system (203) must not be limited to the ignition state of the vehicle and any other means known in the art may also be used to determine the ON or OFF operational state of the infotainment system (203). When the control unit (202) determines the operational state of the infotainment system (203) OFF, no further action is taken. In an embodiment, the control unit (202) may only check for the operational state of the infotainment system (203) when the engine of the vehicle is in the ON condition or when the vehicle is in the running condition. Further, when the control unit (202) determines that the operational state of the infotainment system (203) is in the ON condition, the next step (102) of determining the functional state of the infotainment system (203) is executed.

The second step (102) involves the aspect of determining the functional state of the infotainment system (203) i.e., the media mode or the communication mode. The control unit (202) may determine the functional mode of the infotainment system (203) by any method or system known in the art. For instance, the control unit (202) may determine the functional state of the infotainment system (203) based on the call status of the infotainment system (203). When there is an ongoing call or an incoming call, the control unit may determine that the infotainment system (203) is in the communication mode. Else, the functional state of the infotainment system (203) may be determined as the media mode. The control unit (202) may also determine the functional mode of the infotainment system (203) based on the output from the infotainment system (203). When the control unit (202) detects that the output from the infotainment system (203) is any sort of media, the control unit (202) may infer that the operational state is currently the media mode (103a). Further, the above-mentioned methods of determining the functional mode of the infotainment system (203) is only exemplary in nature and the same must not be considered as a limitation as any known methods in the art may be used to determining the functional mode of the infotainment system (203).

Further, when the control unit (202) determines that the operational state of the infotainment system (203) is the media mode (103a), the control unit begins to monitor the ambient noise inside the cabin of the vehicle at the step (104). The monitoring of the ambient noise inside the cabin of the vehicle involves, initially receiving the ambient noise by the receiving unit (200a) of the control unit (202). The ambient noise may include the conversations of the passengers among themselves or with the driver in the vehicle. The ambient noise may also include the noise from the surroundings of the vehicle. The external sources of noise apart from the output of the infotainment system (203) that creeps into the cabin of the vehicle may herein be defined as the ambient noise. This ambient noise is further processed or analyzed by the processing module (202b) of the control unit (202). The processing module (202b) may quantify the level of the ambient noise that is picked up by the microphones (201). The processing module (202b) may determine the loudness of the ambient noise inside the cabin of the vehicle. Further, the determined level of the ambient noise may be compared with the pre-determined threshold level by the comparison module (202c) of the control unit (202). The pre-determined threshold level or the pre-determined threshold loudness may range from 68 db to 72 db. The comparison module (202c) compares the level of the ambient noise with the pre-determined threshold level and if the level of the ambient noise is greater than the pre-determined threshold level, the control unit may determine that the output of the infotainment system (203) is elevated. Consequently, the control unit (202) interprets that the loudness or the level of the noise from the conversation by the passengers is greater and a regulating module (202d) of the control unit (202) modulates the output of the infotainment system (203) subsequently. When the control unit (202) determines that the ambient noise is greater than the pre-determined threshold level, the regulating module (202d) may decrease the output from the speakers (203b) of the infotainment system (203) thereby increasing the audibility of the passengers. The regulating module (202d) may decrease the output from the speakers (203b) of the infotainment system (203) by a pre-determined level below the threshold level thereby, inherently amplifying the conversation of the passengers. The above process may be continual in nature and the control unit (202) may constantly check for the level of the ambient noise. Further, as the conversation of the passengers fades away or as the level of ambient noise reduces and falls below the pre-determined threshold level inside the cabin of the vehicle, the regulating module (202d) may modulate the output of the speakers back to the normal or the pre-set level in the infotainment system (203). In an embodiment, the user may vary the pre-determined threshold level. The user may vary the threshold level through the I/O interface (203a) of the infotainment system (203) and may adjust in accordance with their convenience.

With further reference to the step (102), when the control unit determines that the functional state of the infotainment system (203) is the communication mode (103b), the control unit (202) proceeds to monitor the ambient noise. The control unit (202) may determine the operational state as the communication mode (103b) when the user initiates or receives an incoming call through the infotainment system (203). As mentioned in the above step (104), the control unit (202) receives and determines the level of the ambient noise. Further, the level of the determined ambient noise may be compared with the pre-determined threshold level as mentioned in the step (104). The comparison module (202c) compares the level of noise in the call with the pre-determined threshold level and if the level of the noise in the call is lower than the pre-determined threshold level, the control unit may determine that the output of the infotainment system is low. Further, the level of noise in the call may herein be the output from the infotainment system (203) during the call. The pre-determined threshold level for the communication mode may be set based on the ambient noise in the cabin of the vehicle. The ambient noise in the cabin of the vehicle may be taken into consideration for determining and establishing the threshold level. For instance, when the ambient noise in the cabin is high-pitched, the incoming noise from the call becomes attenuated and the user often finds it difficult to hear and communicate under such circumstances. Therefore, the threshold level may be set at lower levels based on the ambient noise when the functional mode of the infotainment system (203) is in the communication mode (103b). When the control unit (202) determines that the level of the noise over the call is lower than the pre-determined threshold level, the regulating module (202d) may increase the output from the speakers (203b) of the infotainment system (203) thereby increasing the audibility of the call. The regulating module (202d) may increase the output from the speakers (203b) of the infotainment system (203) by a pre-determined level above the threshold level thereby, inherently amplifying the conversation over the call. The above process may be continual in nature and the control unit (202) may constantly compare the level of the noise over call with the threshold level. Further, as the call through the infotainment system (203) ends, the regulating module (202d) may decrease the output of the speakers back to the normal or the pre-set level. In an embodiment, the user may activate or turn off the automatic modulation of the output form the infotainment system by a switch, a knob, the I/O interface etc.

In an embodiment, the user interference in adjusting the output of the infotainment system (203) is reduced due to the automatic modulation of the infotainment system (203) in the above-mentioned method. In an embodiment, the infotainment system (203) is automatically modulated based on the ambient noise during a call without any user intervention, and thereby avoids distractions to the driver. This greatly improves safety in the vehicle.

The various singular/plural permutations may be expressly set forth herein for sake of clarity.

It will be understood by those within the art that, in general, terms used herein, are generally intended as "open" terms (e.g., the term "including" should be interpreted as "including but not limited to," the term "having" should be interpreted as "having at least," the term "includes" should be interpreted as "includes but is not limited to," etc.). It will be further understood by those within the art that if a specific number of an introduced claim recitation is intended, such an intent will be explicitly recited in the claim, and in the absence of such recitation no such intent is present. For example, as an aid to understanding the description may contain usage of the introductory phrases "at least one" and "one or more" to introduce claim recitations.
