It should also be further understood that the term "and / or" used in the specification of the present invention and the claims refers to any combination of one or more of the associated listed items and all possible combinations, and includes these combinations.

[0024] See also Figure 1 The present invention provides an alarm control method based on a cockpit entertainment controller, which is applied to the broadcast control of vehicle speakers, especially to the alarm control of vehicles. The present invention stores the alarm sound file in the cockpit entertainment controller, distinguishes the needs of different types of alarms, calls different types of alarm sound files, and distributes the audio to different speakers of the whole vehicle through the A2B digital audio bus for sounding. Specifically, Figure 2 shown.

[0025] In the traditional solution, each ECU processes alarm information independently, uses alarm sound files stored in the instrument or speaker, and alarms independently. There is a lack of unified management, and the alarm method is also relatively simple.

[0026] The present invention receives alarm information from other controller ECUs through the cockpit entertainment controller, and sends the alarm information to the cockpit entertainment domain controller through CAN / CANFD. The cockpit entertainment domain controller MCU processes the alarm priority, reports the alarm information to the cockpit entertainment controller SOC, retrieves the alarm sound source through the A2B digital audio bus, and sends the alarm sound to the power amplifier AMP, which amplifies the sound and then sends it to speakers in different areas for sounding.

[0027] In the present invention, the vehicle speakers include a left front area speaker, a right front area speaker, a left rear area speaker, a right rear area speaker, a front area speaker, and a rear area speaker. In some other embodiments, the area speakers may be reduced or increased, but the overall control method remains unchanged.

[0028] Specifically, S100: different alarm sound files are stored in the cockpit entertainment controller, which can be called by the cockpit entertainment controller, and the alarm sound files are broadcast through the vehicle speakers to remind the driver.

[0029] S200: receiving alarm information sent by other ECUs, and determining a target vehicle speaker for broadcasting an alarm sound file according to the alarm information, wherein the alarm sound file corresponds to the alarm information.

[0030] The alarm information sent by other ECUs to the cockpit entertainment controller, for example, if the front radar detects an obstacle ahead, the ECU managed by the front radar sends an alarm message to the cockpit entertainment controller. The cockpit entertainment controller receives the alarm information sent by other ECUs and determines the target vehicle speaker to broadcast the alarm sound file according to the alarm information.

[0031] In the present invention, the alarm sound file corresponds to the alarm information, and it can be understood that different alarm information corresponds to different alarm sound files. For example, the sound of a radar alarm is different from the sound of a fault alarm.

[0032] S300: The cockpit entertainment controller calls the alarm sound file corresponding to the alarm information, and controls the target vehicle speaker to play the alarm sound file.

[0033] In one embodiment, the cockpit entertainment controller determines the alarm type and the alarm location according to the alarm information, and determines the target vehicle speaker for broadcasting the alarm sound file according to the alarm location.

[0034] For example, the alarm type can be determined by the fault code included in the alarm information, and the alarm position of the ECU can be determined according to the ECU ID in the alarm information. The tire pressure of the left rear side of the vehicle is abnormal, and the ECU sends an alarm message of abnormal tire pressure. The alarm message contains the tire pressure fault code and the ECU ID. Therefore, the cockpit entertainment controller can determine the alarm sound file for reporting tire pressure failure. Because the tire pressure is abnormal on the left rear side, the left rear area speaker can be determined as the target vehicle speaker.

[0035] In another example, the cockpit entertainment controller determines the alarm location according to the ECU identification address or identifier in the alarm information. When the ECU communicates with the cockpit entertainment controller via CAN / CANFD, the alarm information sent includes the ECU identification address or identifier. Of course, the cockpit entertainment controller determines the alarm type according to the information content such as the identifier or fault code in the alarm information.

[0036] In the present invention, the position of the ECU in the vehicle or the position of the information source in the alarm information is consistent with the alarm position, and the alarm position is consistent with the position of the target vehicle speaker. Therefore, the position of the target vehicle speaker can be determined by determining the position of the ECU. It should be understood that the position of the ECU represents the alarm position, which is not necessarily the position where the ECU is actually installed on the vehicle, but is only used to characterize the position of the alarm information reminder.

[0037] In another embodiment, the cockpit entertainment controller classifies the alarm information and determines the target vehicle speaker according to the category of the alarm information. The present invention classifies the categories of alarm information and controls the alarm control of the vehicle according to the classification, which is more conducive to unified control and notification of alarm events.

[0038] For example, the front radar alarm, front collision warning, turn signal prompt, general fault and general prompt are classified as the front alarm information. The left vehicle alarm, left door open alarm and left obstacle alarm are classified as the left side alarm information. The right vehicle alarm, right door open alarm and right obstacle alarm are classified as the right side alarm information. The reversing radar alarm and rear collision warning are classified as the rear side alarm information.

[0039] Through the above method, the spatial stereoscopic sense of the warning is increased, and the user's recognition of the warning direction is improved, as described in detail below.

[0040] When other ECUs send alarms for the front radar alarm, front collision warning, general fault or general prompt in the front alarm information, the cockpit entertainment controller distributes the alarm sound file corresponding to the front alarm information to the left front area speaker, the right front area speaker or the front area speaker for playback. When multiple ECUs send alarms, the cockpit entertainment controller distributes the alarm sound file to the left front area speaker and the right front area speaker, or to the left front area speaker and the front area speaker for playback, or to the right front area speaker and the front area speaker for playback, or to the left front area speaker, the right front area speaker and the front area speaker for playback.

[0041] Usually, general prompts are only broadcasted on the left front area speaker or the right front area speaker, corresponding to the driver's position. For example, when the vehicle turns left, the cockpit entertainment controller calls the alarm sound file and distributes it to the left front area speaker through the digital audio bus A2B for broadcast; when the vehicle turns right, the cockpit entertainment controller calls the alarm sound file and distributes it to the right front area speaker through the digital audio bus A2B for broadcast; When other ECUs send alarms such as left-side vehicle approaching alarm, left-side door opening alarm, and left-side obstacle alarm, the cockpit entertainment controller assigns the alarm audio file corresponding to the left-side alarm information to the left front area speaker or the left rear area speaker for broadcast. When multiple ECUs send alarms, the cockpit entertainment controller assigns the alarm audio file to the left front area speaker or the left rear area speaker, or to the left front area speaker and the left rear area speaker.

[0042] When other ECUs send alarms such as right-side vehicle approaching alarm, right-side door opening alarm, and right-side obstacle alarm, the cockpit entertainment controller assigns the alarm audio file corresponding to the right-side alarm information to the right front area speaker or the right rear area speaker for broadcast. When multiple ECUs send alarms, the cockpit entertainment controller assigns the alarm audio file corresponding to the right-side alarm to the right front area speaker or the right rear area speaker, or to the right front area speaker and the right rear area speaker.

[0043] When other ECUs send alarms such as reversing radar alarm and rear collision warning in the rear side alarm information, the cockpit entertainment controller allocates the alarm sound file corresponding to the alarm information on the right side of the vehicle to the speakers in the rear area for broadcast.

[0044] Furthermore, when other ECUs send different seat belt unfastened warning sounds, voice broadcasts are also performed in different areas.

[0045] When the driver's seat belt is not fastened and the alarm sounds, the cockpit entertainment controller will assign the corresponding alarm sound file to the left front area speaker for playback.

[0046] When the passenger seat belt is not fastened and the alarm sounds, the cockpit entertainment controller will assign the corresponding alarm sound file to the right front area speaker for playback.

[0047] When the left rear seat belt is not fastened and the alarm sounds, the cockpit entertainment controller will assign the corresponding alarm sound file to the left rear area speaker for playback.

[0048] When the right rear seat belt is not fastened and the alarm sounds, the cockpit entertainment controller will assign the corresponding alarm sound file to the right rear area speaker for playback.

[0049] When the middle rear seat seat belt is not fastened and the alarm sounds, the cockpit entertainment controller will assign the corresponding alarm sound file to the rear area speakers for playback.

[0050] The seat belts can be controlled by multiple ECUs, and multiple ECUs send alarm information to the cockpit entertainment controller. Therefore, the driver's seat belt unfastened alarm can be classified as the left side of the car alarm information, the passenger seat belt unfastened alarm can be classified as the right side of the car alarm information, the left rear seat seat belt unfastened alarm can be classified as the left side of the car alarm information, the right rear seat seat belt unfastened alarm can be classified as the right side of the car alarm information, and the middle seat seat belt unfastened alarm can be classified as the rear side of the car alarm information.

[0051] After the alarm information is categorized, the cockpit entertainment controller can control the vehicle speakers more accurately. For example, if an alarm is needed on the left side of the vehicle and music is currently playing in the entire vehicle, the speakers on the right side of the vehicle can continue to play music, while the speakers on the left side of the vehicle can stop playing music and play the corresponding alarm sound file.

[0052] Based on the above scheme, the present invention realizes the alarm control of the vehicle based on the cockpit entertainment controller. The alarm sound file is stored in the cockpit entertainment controller and can be directly called. The cockpit entertainment controller can alarm according to the information of other ECUs, thereby achieving the purpose of unified control of the alarm and realizing the sound of speakers in specific areas, thereby reducing the power consumption of the audio system, increasing the spatial stereoscopic sense of the warning, and improving the user's recognition of the warning direction.

[0053] See also Figure 3 The present invention also provides an alarm control device based on a cockpit entertainment controller, comprising: The configuration module 31 is used to store the alarm sound file in the cockpit entertainment controller.

[0054] The control module 32 is used to receive alarm information sent by other ECUs, and determine a target vehicle speaker for broadcasting an alarm sound file according to the alarm information, wherein the alarm sound file corresponds to the alarm information.

[0055] The playing module 33 is used to call the alarm sound file corresponding to the alarm information and control the target vehicle-mounted speaker to play the alarm sound file.

[0056] The control module 32 is also used to determine the alarm type and alarm position according to the alarm information, and determine the target vehicle speaker for broadcasting the alarm sound file according to the alarm position. For example, the alarm position is determined according to the ECU identification address or identifier in the alarm information; the alarm type is determined according to the information content in the alarm information; wherein the position of the ECU in the vehicle or the position of the information source in the alarm information is consistent with the alarm position, and the alarm position is consistent with the position of the target vehicle speaker.

[0057] The control module 32 is also used to classify the alarm information and determine the target vehicle speaker according to the category of the alarm information. For example, the front radar alarm, front collision warning, turn signal prompt, general fault and general prompt are classified as the front alarm information; the left vehicle alarm, left door open alarm, and left obstacle alarm are classified as the left side alarm information; the right vehicle alarm, right door open alarm, and right obstacle alarm are classified as the right side alarm information; the reversing radar alarm and rear collision warning are classified as the rear side alarm information.

[0058] Among them, the vehicle speakers include a left front area speaker, a right front area speaker, a left rear area speaker, a right rear area speaker, a front area speaker, and a rear area speaker.

[0059] The control module 32 is also used to: assign the alarm sound file corresponding to the alarm information in the front of the vehicle to the left front area speaker, the right front area speaker or the front area speaker for playback; assign the alarm sound file corresponding to the alarm information on the left side of the vehicle to the left front area speaker or the left rear area speaker for playback; assign the alarm sound file corresponding to the alarm information on the right side of the vehicle to the right front area speaker or the right rear area speaker for playback; assign the alarm sound file corresponding to the alarm information on the rear side of the vehicle to the rear area speaker for playback.

[0060] Furthermore, the control module 32 is also used for: when the driver's seat belt is not fastened and an alarm sounds, the corresponding alarm sound file is allocated to the left front area speaker for playback; when the passenger seat belt is not fastened and an alarm sounds, the corresponding alarm sound file is allocated to the right front area speaker for playback; when the left rear seat seat belt is not fastened and an alarm sounds, the corresponding alarm sound file is allocated to the left rear area speaker for playback; when the right rear seat seat belt is not fastened and an alarm sounds, the corresponding alarm sound file is allocated to the right rear area speaker for playback; when the middle seat seat in the back row is not fastened and an alarm sounds, the corresponding alarm sound file is allocated to the rear area speaker for playback.
