The GNSS controller 124 may be configured to support various current and / or future global or regional location systems such as global positioning system (GPS) , Galileo, Beidou, Global Navigation Satellite System (GLONASS) and the like. Map data used for route planning may be stored in the storage 110 as a part of the vehicle data 126. Navigation software may be stored in the storage 110 as one the vehicle applications 108.
[0020] The computing platform 104 may be configured to wirelessly communicate with a mobile device 128 of the vehicle users / occupants via a wireless connection 130. The mobile device 128 may be any of various types of portable computing devices, such as cellular phones, tablet computers, wearable devices, smart watches, laptop computers, portable music players, or other device capable of communication with the computing platform 104. A wireless transceiver 132 may be in communication with a Wi-Fi controller 134, a Bluetooth controller 136, a radio-frequency identification (RFID) controller 138, a near-field communication (NFC) controller 140, and other controllers such as a Zigbee transceiver, an IrDA transceiver, and configured to communicate with a compatible wireless transceiver 142 of the mobile device 128.
[0021] The mobile device 128 may be provided with a processor 144 configured to perform instructions, commands, and other routines in support of the processes such as navigation, telephone, wireless communication, and multimedia processing. For instance, the mobile device 128 may be provided with location and navigation functions via a GNSS controller 146 and a navigation controller 148. The mobile device 128 may be provided with a wireless transceiver 142 in communication with a Wi-Fi controller 150, a Bluetooth controller 152, a RFID controller 154, an NFC controller 156, and other controllers (not shown) , configured to communicate with the wireless transceiver 132 of the computing platform 104. The mobile device 128 may be further provided with a non-volatile storage 158 to store various mobile application 160 and mobile data 162.
[0022] The computing platform 104 may be further configured to communicate with various components of the vehicle 102 via one or more in-vehicle network 166. The in-vehicle network 166 may include, but is not limited to, one or more of a controller area network (CAN) , an Ethernet audio video bridging (AVB) network, and a media-oriented system transport (MOST) , A2B audio bus, INICnet as some examples. Furthermore, the in-vehicle networks 166, or portions of the in-vehicle network 166, may be a wireless network accomplished via Bluetooth low-energy (BLE) , Wi-Fi, ultra-wide band (UWB) or the like. In one or more examples, the in-vehicle network 166 may include a plurality of networks operating in parallel. For instance, the in-vehicle network 166 may include a CAN configured to manage a vehicle's powertrain, body, and other subsystems, and an A2B audio bus (and / or other high-speed networks) which supports a higher speed and configured to distribute audio, video and multimedia data within a vehicle 102.
[0023] The computing platform 104 may be configured to communicate with various electronic control units (ECUs) 168 of the vehicle 102 configured to perform various operations via the one or more in-vehicle networks 166. For instance, the computing platform 104 may be configured to communicate with a telematics control unit (TCU) 170 configured to control telecommunication between vehicle 102 and a wireless network 172 through a wireless connection 174 using a modem 176. The wireless connection 174 may be in the form of various communication network e.g., a cellular network. Through the wireless network 172, the vehicle may access one or more servers 178 to access various content for various purposes. It is noted that the terms wireless network and server are used as general terms in the present disclosure and may include any computing network involving carriers, router, computers, controllers, circuitry or the like configured to store data and perform data processing functions and facilitate communication between various entities.
[0024] The computing platform 104 may be configured to communicate with one or more zone media controllers 180 configured to perform multimedia functions in one or more zones within the vehicle cabin. The vehicle cabin may be divided into one or more zones (e.g., driver seat, passenger seat) for performing multimedia operations independently. For instance, users sitting in different zones may experience multimedia output without or with little interference.
[0025] Referring to Figure 2, an example block diagram of a vehicle cabin 200 divided into multiple zones of one embodiment of the present disclosure is illustrated. In the present example, the vehicle cabin 200 may be divided into four zones 202 including a first zone 202a located at front-left of the vehicle cabin 200 corresponding to the driver seat; a second zone 202b located at front-right of the vehicle cabin 200 corresponding to the passenger seat; a third zone 202c located at rear-right of the vehicle cabin 200 corresponding to a rear-right seat; and a fourth zone 202d located at rear-left of the vehicle cabin 200 corresponding to the rear-left seat. With continuing reference to Figure 1, each zone 202 may be associated with a zone media controller 180a configured to operate the multimedia functions of the respective zone. More specifically, the first zone 202a may be associated with a first zone media controller 180a, the second zone 202b may be associated with a second zone media controller 180b, the third zone 202c may be associated with a third zone media controller 180c, and the fourth zone 202d may be associated with a fourth zone media controller 180d.
[0026] Each of the zone media controllers 180 may be configured to independently operate and control the multimedia features within the respective zone without or with little interference with the multimedia features of other zones. Taking the first zone media controller 180a for instance, the first zone 202a may be provided with various devices / components to provide the corresponding user (e.g., the driver) with various multimedia features. Additionally or alternatively, one or more zone media controllers 180 may be configured to operate collectively to enable a full cabin multimedia system. One or more zone media controllers 180 corresponding to passenger (e.g., non-driver) seats may operate collectively to enhance passenger entertainment experience. The zone media controller 180 corresponding to the driver seat may be configured to focus on driver support features, such as navigation, driver assistance features of the vehicle system or the like.
[0027] The first zone media controller 180a may be operably connected to one or more displays 204 configured to provide visual output to vehicle user. In some cases, the display 204 may be a touch screen further configured to receive user touch input, while in other cases the display 204 may be a display only, without touch input capabilities. The first zone media controller 180a may be further operably connected to one or more cameras 206 configured to provide video input. For instance, the one or more cameras 206 may include an in-cabin camera mounted on the windshield facing backward and configured to capture facial images of one or more vehicle users. The facial images may be provided to the computing platform 104 for facial recognitions such that the computing platform 104 may determine the identity of the user and occupancy within the first zone 202a.
[0028] The first zone media controller 180a may be further operably connected to one or more loudspeakers 208 configured to provide audio output to the vehicle user located within the first zone 202a. In the present example, the loudspeakers 208 may configured to be zone specific and directed to the user within the respective zone only. As an example, the one or more loudspeakers 208 may be mounted on the headrest of the seat (e.g., driver seat) located within the first zone 202a to direct the audio output to the user. Other users within other zones 202 may not be affected or be little affected by the loudspeakers 208 within the first zone when the volume is adjusted to a preferred level such that the user (e.g., the driver) may clearly hear the audio output by the one or more loudspeakers 208 while causing only minimum interference to other user located within other zones 202. The first zone media controller 180a may be further operably connected to one or more microphones 210 configured to capture voice input of the vehicle user within the first zone 202a. The user may adjust the multimedia operations within first zone 202a by making a voice command via the microphones 210. For instance, the user (e.g., driver) may make a voice command indicating an intent to change a radio channel via the microphone 210 of the first zone 202a, in response the computing platform 104 in combination with the first zone media controller 180a may switch to the desired radio channel for the first zone 202a only, without modifying multimedia settings of other zones 202.
[0029] The first zone media controller 180a may be further operably connected to one or more lighting devices (e.g., LEDs) 212 configured to providing light output to the first zone 202a. The lighting device 212 may include one or more atmosphere lights configured to provide the user with a desired atmosphere by adjusting the characteristics of the light output such as color, intensity, and pattern. The first zone media controller 180a may determine and adjust the atmosphere based on the multimedia content being output within the first zone 202a. The first zone media controller 180a may be further operably connected to one or more vibrators 214 configured to provide haptic feedback to the user within the first zone 202a e.g., based on the multimedia content. The first zone media controller 180a may be further operably connected to one or more sensors 216 configured to perform measurements with regard to one or more conditions within the first zone 202a. For instance, the sensors 216 may include an occupancy sensor configured to detect the presence or occupancy of the seat within the first zone 202a. Additionally or alternatively, the sensors 216 may include a biometric sensor (e.g., electrocardiogram) configured to measure biometric conditions or biometric information associated the user. The sensors 216 may be located within the corresponding vehicle seat to facilitate the measurement.
[0030] The displays 204, cameras 206, loudspeakers 208, microphones 210, lighting devices 202, vibrators 214, sensors 216 as well as other associated hardware devices may be collectively referred to as multimedia devices in one or more examples of the present disclosure. The multimedia devices may be configured to provide various multimedia features described herein. For instance, the multimedia features may include a video output feature enabled by the display 204, and a video input feature enabled by the cameras 206. Additionally, the multimedia features may include an audio output feature enabled by the loudspeakers 208, and an audio input feature enabled by the microphone 210. Additionally, the multimedia features may include a light output feature enabled by the lighting devices 212, and a vibration and / or haptic output feature enabled by the vibrator 214. Additionally, the multimedia features may include a senor measurement and / or detection feature enabled by the sensors 216.
[0031] Each of the rest zone media controllers 180b, 180c, 180d associated with rest zones 202b, 202c, 202d may be configured in the same or similar manner to the first zone media controller 180a. For instance, each of the rest zone media controllers 180b, 180c, 180d may be operably connected to one or more multimedia devices such as cameras, displays, microphones, loudspeakers, lighting devices, vibrators, sensors or the like to control the operations thereof. Detailed description will not be repeated therein for simplicity.
[0032] With the multi-zone configuration described above, each user located within separate zones may experience customized multimedia content individually. For instance, the driver located at the first zone 202a may listen to a radio channel via the loudspeakers 208 while using the navigation output via the display 204. In addition, a passenger located at the third zone 202c may live stream a video via a mobile device 128 with the audio sound output via one or more loudspeakers located within the third zone 202c. The video images may be output via the display of the mobile device 128. Additionally or alternatively, the video images may be output via the display associated with the third zone 202c.
[0033] It is noted that although four zones 202 and four zone media controllers 180 are illustrated in the example in Figure 2, the present disclosure is not limited thereto. Depending on the specific configuration of the vehicle cabin 200, more or less zones may be defined. In one or more alternative examples, a single zone 202 may cover multiple seats. E. g., the entire back bench seat may be defined as in one zone. In one or more alternative examples, the vehicle 102 may include three rows of seats, and may be configured to include a front-row zone, a second-row zone, and a third-row zone. In one or more alternative examples, the bench seat may be configured to accommodate third vehicle users, and the vehicle 102 may be configured to include a left zone, a middle zone, and a right zone.
[0034] In one or more further alternative examples, different zones 202 may share the same components for cost savings. For instance, the first zone 202a and second zone 202b may share a single camera 206. In this case, the second zone 202b may not be provided with its own dedicated camera. When images of the second zone 202b need to be captured, the second zone media controller 180b may access the camera 206 via the first media controller 180a. In an alternative case, the third zone 202c and the fourth zone 202d may share a single display.
[0035] It is further noted that although each zone 202 correspond to a zone media controller 180 in the example illustrated with reference to Figure 2, the present disclosure is not limited thereto. In one or more alternative examples, one zone media controller 180 may be configured to operate the multimedia features of multiple zones 202.
[0036] It is further noted that although each of the zone media controllers 180 is individually connected to the computing platform 104 via the in-vehicle network 166, the present disclosure is not limited thereto. Figure 3A and 3B illustrates examples in which one or more zone media controllers 180 may be connected to the computing platform 104 in different embodiments of the present disclosure. Referring to Figure 3A, a first alternatively example in which the one or more zone media controllers 180 are connected to the computing platform 104 is illustrated. In the present example, the zone media controllers 180 may be connected to the computing platform 104 in a serial manner. E. g., subsequent zone media controllers 180 may be connected to the computing platform 104 via one or more prior zone media controllers 180 without a direct access to the in-vehicle network 166. As illustrated in Figure 3A, the first zone media controllers 180a may be connected to the computing platform 104 via the in-vehicle network 166. The second zone media controllers 180b may be connected to the first zone media controllers 180a without a direct access to the in-vehicle network 166. The third zone media controllers 180c may be connected to the second zone media controllers 180b without a direct access to the in-vehicle network 166. The fourth zone media controllers 180d may be directly connected to the third zone media controllers 180d without a direct access to the in-vehicle network 166. In the present example, the second zone media controllers 180b, the third zone media controllers 180c and the fourth zone media controllers 180d are not directly connected to the in-vehicle network 166 which reduces a physical connector requirement of the in-vehicle network 166. In one example, only one connector (or a single connector) from the in-vehicle network 166 is required to drive all four zone media controllers 180.
[0037] Referring to Figure 3B, a second alternative example in which the one or more zone media controllers 180 are connected to the computing platform 104 is illustrated. In the present example, the first zone media controllers 180a may be connected to the computing platform 104 via the in-vehicle network 166. The second zone media controllers 180b may be connected to the first zone media controllers 180a without a direct access to the in-vehicle network 166. The fourth zone media controllers 180d may be connected to the computing platform 104 via the in-vehicle network 166. The third zone media controllers 180c may be connected to the fourth zone media controllers 180d without a direct access to the in-vehicle network 166. The second media controller 180b and the third media controller 180c may be inter-connected to each other to provide a connection redundancy. For instance, if the fourth zone media controller 180d has become unavailable, the third zone media controller 180c may still access the in-vehicle network 166 via the first zone media controller 180a and the third zone media controller 180b.
[0038] Referring to Figure 4, an example block diagram of media zone controllers of one embodiment of the present disclosure is illustrated. With continuing reference to Figures 1-3, the first zone media controller 180a is operably connected to the computing platform 104 via one or more in-vehicle network 166. As described above, the in-vehicle network 166 may include wired and / or wireless communication network in support of various protocols. In the present example, it is preferred that the zone media controller 180 communicating with the computing platform 104 via high speed network due to the larger size of multimedia data (e.g., video, audio) . Therefore, the in-vehicle network 166 in the present example may include one or more of an Ethernet audio video bridging (AVB) network, and a media-oriented system transport (MOST) , A2B audio bus, INICnet as some examples. The controller area network (CAN) is not preferred due to the low speed / bandwidth.
[0039] As illustrated in Figure 4, the computing platform 104 and the first zone media controller 180a may bidirectionally communicate data / command 402 via the in-vehicle network 166. In the sending mode, the computing platform 104 encodes the data / command 402 via an encoder / decoder (endec) 404 configured to encode and decode digital data. The endec 404 may be configured to support various encoding protocols. For instance, the in-vehicle network 166 in the present example may be in support of data protocols that is originally design for audio data communication only and does not fully support digital data for other multimedia content. In this case, the endec may be configured to encode the command / data 402 using an everything-to-audio (XOA) protocol to encode the data / command 402 into encoded data that is compatible with the in-vehicle network 166 for transmission. The encoded data may then be sent to a first interface 406a corresponding to the first zone media controller 180a via a buffer 408. In the present example, the computing platform 104 may be provided a plurality of interfaces 406 each corresponding to a zone media controller 180. The first interface 406a may be operably connected to a first controller interface 408a of the first zone media controller 180a. An nth interface 406n may be operably connected to an nth controller interface 408n of an nth zone media controller 180n. Alternatively, a single interface 406 may be configured to correspond to a plurality of zone media controllers 180.
[0040] For simplicity, only the first zone media controller 180a will be described in detail. Other zone media controllers 180 may operate in the same or similar manner to the first zone media controller 180a. The first zone media controller 180a may communicate with the computing platform 104 via the first controller interface 408a through the in-vehicle network 166. Once the encoded data is received by the first controller interface 408a, the encoded data is forwarded to a digital signal processor (DSP) 410 via a buffer 412 for further processing. More specifically, the DSP 410 may be configured to enable an endec 414 configured to decode the encoded data (e.g., using XOA protocol) such that the original command / data 402 is restored.
[0041] The first zone media controller 180 may perform various operations based on the command / data 402. In the present example, the first zone media controller 180 may be configured to communicate with one or more components via one or more input / output (I / O) interfaces 416. More specifically, the first zone media controller 180a may be operably connected to one or more of the light devices 212, microphones 210, loudspeakers 208, cameras 206, displays 204, vibrators, sensors 216, and other devices 418 via the I / O interfaces 416. The command / data 402 may include a user command indicative of an intent to adjust an operation of one or more components connected to the first zone media controller 180a (e.g., adjust the volume of the loudspeaker 208, activation of the light device 212, activation of the vibrator 214) . Additionally or alternatively, the command / data 402 may include one or more multimedia data file (e.g., audio, video) for output via the one more components.
[0042] In an alternative example, data may be sent from the first zone media controller 180a to the computing platform 104. For instance, sensor data measured by the one or more sensors 216 may be encoded via the endec 414 of the DSP 410 and transferred to the computing platform 104. Once received, endec 404 may decode the data and the computing platform 104 may perform operations accordingly.
[0043] Referring to Figure 5, an example flow diagram of a process 500 for operating multimedia output in different zones of one embodiment of the present disclosure is illustrated. With continuing reference to Figures 1 to 4, the process 500 may be implemented via the computing platform 104 in combination with one or more zone media controllers 180.
[0044] At operation 502, the computing platform 104 detects the vehicle occupancy in each zone 202 in response to one or more users has entered the vehicle 102. The vehicle occupancy may be detected in various manners. For instance, the computing platform 104 may use sensor data received from one or more sensors 216 from each zone 202 to detect if the zone 202 is occupied. Additionally or alternatively, the computing platform 104 may use the one or more cameras 206 to detect the presence of one or more users in each zone 202.
[0045] At operation 504, in response to detecting the occupancy of the vehicle 102, the computing platform 104 activates the zone media controllers 180 corresponding to the occupied zones. Other zone media controllers 180 corresponding to the unoccupied zones may remain or enter lower power mode. Alternatively, all zone media controllers 180 may remain in the low power mode until the users start to use the multimedia features in the corresponding zone.
[0046] At operation 506, the computing platform 104 receives a user input indicative of an intent to use the multimedia features. The user input may be received in various manners. For instance, the user my make the user input on one or more touch screen display 204 corresponding to one or more zones. Additionally or alternatively, the user input may be received as a voice command captured via the one or more microphones 210 associated with one or more zones 202. Additionally or alternatively, the user input may be received wirelessly via the wireless transceiver 132 from a mobile device 128 associated with the user.
[0047] In response, at operation 508, the computing platform 104 automatically detects the zone in which the initiating user is located such that the multimedia features may provided correctly. Continuing with the above examples, if the user input is locally received via the device components associated with one or more zone media controllers 180 (e.g., via the display 204, microphone 210) , the automatically zone detection will be relatively easy. The computing platform 104 may determine the zone as being associated with the zone media controllers 180 where the user input is received. For instance, if the user touch input is received via the touchscreen display 204 associated with the third zone media controller 180c, the computing platform 104 may automatically identify the third zone 202c to provide the multimedia features.
[0048] Otherwise, if the user input is remote and wirelessly received, the zone detection process may be more complicated. In one or more examples, the computing platform 104 may capture images of the users in the vehicle cabin 200 via one or more cameras assisted by facial recognition technology in an attempt to identify which user is initializing the user input. For instance, the identity of one or more vehicle users and their associated mobile devices 128 may be stored in the storage 110 as a part of the vehicle data 126. Responsive to a successful identification of a vehicle user located within a zone 202, the computing platform 104 may identify the corresponding zone 202 to provide the multimedia features.
[0049] At operation 510, the computing platform 104 determines of the automatic zone detection is successful. In some cases, the computing platform 104 may be unable to automatically detect the zone in which the user input is initiated. If this case, the process proceeds to operation 512 for manual selection.
[0050] At operation 512, the computing platform 104 requests the user to manually select the zone for providing the multimedia features. The request may be provided in various manners. For instance, the computing platform 104 may output an interface illustrating all zones via one or more displays 204 associated with one or more zone media controllers 180 and ask user to make an input via the touch screen. Additionally or alternatively, the computing platform 104 may detect the user location via microphone triangulations. For instance, the initiating user may first be requested to make a voice utterance detectable by a plurality of microphones 210 associated with different zones. In general, the voice utterance may be best detected by a microphone 210 that is the closest to the user (e.g., with the loudest volume) . By comparing the voice utterance detected by the plurality of microphones, the computing platform 104 may determine the zone in which the user is located.
[0051] At operation 514, responsive to automatically or manually detecting the selected zone 202, the computing platform communicates with the corresponding zone media controller 180 for multimedia content output.
[0052] At operation 516, the computing platform 104 and / or the corresponding zone media controller 180 adjusts the settings in the selected zone based on user input within interfering the settings of other zones. For instance, the user may adjust the loudspeaker volume within the selected zone while the audio settings for other zones remain the same.
[0053] The process returns to operation 506 such that another user located within another zone 202 may independently enable other multimedia features thereof.
