Technical Field

[0001] This invention relates to the field of automotive sound control, and more specifically, to a warning sound control method and device. Background Technology

[0002] With the rapid development of modern automotive technology, vehicle safety and driving experience are receiving increasing attention.

A user's refusal to process personal information beyond what is necessary for basic functions will not affect the user's use of basic functions.

[0061] Figure 1 This is a schematic diagram of the alarm sound control system according to an embodiment of the present invention. Figure 1 As shown, the warning sound control system includes a vehicle control device 11, a server 12, and a user terminal 13.

[0062] In this embodiment, the vehicle control device 11 is a device connected to the warning sound playback device on the target vehicle to control the warning sound playback device to play warning sounds. The connection method can be wired or wireless. The target vehicle can be any type of vehicle. The vehicle type can include power subtype, vehicle type subtype, and vehicle usage subtype, etc. For example, the power subtype can include rickshaws, electric vehicles, fuel vehicles, and hybrid vehicles; the vehicle type subtype can include bicycles, motorcycles, cars, and buses, etc.; and the vehicle usage subtype can include private cars, shared cars, etc. All of the above subtypes can be combined arbitrarily. The following explanation will use a shared electric bicycle as an example.

[0063] In one possible implementation, the vehicle control device 11 can control and manage the central control unit of various functions of the target vehicle, so as to receive signals from various sensors and user inputs, and control the working status of the warning sound playback device according to these signals.

[0064] In one possible implementation, the vehicle control device 11 can be a terminal device bound to the target vehicle. The vehicle control device 11 is a general-purpose terminal that can run applications or mini-programs of the shared electric bicycle operation platform. The terminal can be a smartphone, tablet, in-vehicle computer, smart wearable device, laptop, or other types of mobile communication terminal.

[0065] User terminal 13 is a general-purpose terminal capable of running applications or mini-programs for the shared electric bicycle platform. This terminal can be a smartphone, tablet, in-vehicle computer, smart wearable device, laptop, or other types of mobile communication terminal. In some possible implementations, the vehicle control device user terminal 13 can also be a dedicated terminal with a corresponding application embedded in an application-specific integrated circuit (ASIC). The open platform provides third-party developers with Application Programming Interfaces (APIs), enabling them to develop their own mini-programs based on the platform. Specifically, these mini-programs can be programs developed based on applications within the platform and used to perform corresponding operations.

[0066] Server 12 is a general-purpose data processing device that provides computing or application services to the client of the shared electric bicycle operation platform. It can be a single computer, a cluster of multiple computers, or a cloud server that can flexibly adjust computing resources through cloud technology.

[0067] The warning sound control system in this embodiment can automatically emit a warning sound from the target vehicle based on the interaction between the vehicle control device 11 and the server 12.

[0068] In one possible implementation, before the vehicle control device 11 and the server 12 interact, a personalized warning sound setting stage may be included. During this stage, the server 12 interacts with the user terminal 13 via a network to obtain the user-customized warning sound setting parameters.

[0069] Figure 2 This is an interactive flowchart of the personalized alarm sound setting method according to an embodiment of the present invention. Figure 2 As shown, the interactive process of the personalized alarm sound setting method includes the following steps:

[0070] In step S201, the user terminal 13 sends an alarm sound setting request to the server 12.

[0071] Specifically, after obtaining the user's request to set an alarm sound based on human-computer interaction, the user terminal 13 generates and sends an alarm sound setting request to the server 12.

[0072] Optionally, the user terminal 13 displays a main page containing an alarm sound setting control, and in response to the alarm sound setting control being triggered, sends an alarm sound setting request to the server 12.

[0073] In step S202, server 12 responds to the alarm sound setting request sent by the user terminal by determining the corresponding alarm sound setting page.

[0074] Specifically, the URL of the alert sound settings page can be determined.

[0075] In step S203, server 12 sends an alert sound setting page to user terminal 13.

[0076] In step S204, the user terminal 13 displays the alarm sound settings page.

[0077] The warning sound settings page includes various warning sound setting parameter types and corresponding parameter selection ranges to prompt users to select parameters from the corresponding parameter selection ranges.

[0078] Figure 3 This is a schematic diagram of the alarm sound settings page according to an embodiment of the present invention. Figure 3As shown, the alert sound settings page 300 includes multiple alert sound level parameter setting containers 301 and a confirmation control 30. The alert sound level parameter setting containers 301 are used to display multiple parameter types corresponding to the alert sound level and receive the corresponding parameter values. The confirmation control 305 is used to generate user-personalized alert sound setting parameters bound to the user identifier after being triggered, and send the user-personalized alert sound setting parameters to the server 12.

[0079] The warning sound level parameter setting container 301 includes a warning sound type input control 302, a warning sound volume input control 303, and a warning sound playback frequency input control 304.

[0080] The alert sound type input control 302 is used to obtain the alert sound type selected by the user after being triggered. The alert sound type can be different songs or melodies, etc. The alert sound type can vary according to different alert sound levels.

[0081] The alert sound volume input control 303 is used to obtain the alert sound volume selected by the user after being triggered. Different alert sound levels correspond to different selectable volume ranges. The higher the level, the higher the starting point of the corresponding volume range. For example, the alert sound level is one, and the corresponding volume range is 40-50. The alert sound level is two, and the corresponding volume range is 30-40. The alert sound level is three, and the corresponding volume range is 20-30.

[0082] The warning sound playback frequency input control 304 is used to obtain the warning sound playback frequency selected by the user after being triggered. Different warning sound levels correspond to different ranges of selectable playback frequencies. The higher the level, the higher the starting point of the corresponding playback frequency range. For example, the warning sound level is one, and the corresponding selectable playback frequencies are level one and level two; the warning sound level is two, and the corresponding selectable playback frequencies are level three and level four; the warning sound level is one, and the corresponding selectable playback frequencies are level five and level six. The playback frequency is inversely proportional to the level.

[0083] Optionally, the selectable ranges of the aforementioned alert tone type, alert tone volume, and alert tone volume are determined by the server using the alert tone setting strategy generation model. The alert tone setting strategy generation model can generate multiple alert tone setting strategies, each including various alert tone setting parameter types and corresponding selectable parameter ranges.

[0084] It is worth noting that, Figure 3 The warning sound settings page shown is for illustrative purposes only, and this embodiment does not limit the information and layout contained in the warning sound settings page.

[0085] In step S205, in response to the triggering of the determination control, the user terminal 13 generates alarm sound setting parameters for the user's personalized settings that are bound to the user identifier.

[0086] In step S206, the user terminal 13 sends the user-personalized alarm sound setting parameters to the server 12.

[0087] Step S207: Server 12 stores the user-personalized alarm sound setting parameters.

[0088] pass Figure 2 The method for personalizing the warning sound settings shown can be used to enter the warning sound control process after determining the user's personalized warning sound settings parameters.

[0089] In one possible implementation, the vehicle control device 11 interacts with the server 12 via a network to determine the playback of the control warning sound.

[0090] Figure 4 This is an interactive flowchart of the alarm sound control method according to an embodiment of the present invention. Figure 4 As shown, the interaction flow of the warning sound control method includes the following steps:

[0091] In step S401, the vehicle control device 11 collects the driving information of the target vehicle.

[0092] The driving information includes speed information and environmental information.

[0093] In step S402, the vehicle control device 11 determines the target warning sound level based on the speed information and the environmental information.

[0094] The warning sound levels are respectively mapped to the speed information and the environmental information.

[0095] In one possible implementation, a first warning sound level can be determined based on the speed information, a second warning sound level can be determined based on the environmental information, and then a target warning sound level can be determined based on the first and second warning sound levels according to a first preset rule. The first preset rule can be taking the maximum value, prioritization, or weighted summation and rounding. Taking the maximum value means determining the larger of the first and second warning sound levels as the target warning sound level. Priority sorting refers to pre-setting the priority between the warning sound level determined based on the sound information and the warning sound level determined based on the environmental information; for example, if the first warning sound level is lower than 3, the second warning sound level is given priority, and if the first warning sound level is higher than 3, the first warning sound level is given priority. Weighted summation and rounding means pre-setting the weights corresponding to the speed information and environmental information, and taking the integer part of the weighted summation of the first and second warning sound levels as the target warning sound level.

[0096] Optionally, the speed information includes driving speed, driving acceleration, and / or driving angular velocity, and the warning sound level has a corresponding mapping relationship with the driving speed, driving acceleration, and / or driving angular velocity. Based on the driving speed, driving acceleration, and / or driving angular velocity, corresponding candidate warning sound levels are determined. According to a second preset rule, the first warning sound level is determined based on each candidate warning sound level. The second preset rule is to take the maximum value, prioritize, or perform a weighted summation and rounding.

[0097] Optionally, the environmental information includes noise information, light information, time information, weather information, and / or pedestrian information. The warning sound level has a corresponding mapping relationship with the noise information, light information, time information, weather information, and pedestrian information. Based on the noise information, light information, time information, weather information, and / or pedestrian information, corresponding candidate warning sound levels are determined. According to a third preset rule, the second warning sound level is determined based on each candidate warning sound level. The third preset rule is to take the maximum value, prioritize, or perform weighted summation and rounding.

[0098] The pedestrian information includes surrounding environment images. The candidate warning sound level is determined based on the pedestrian information. Specifically, multiple surrounding environment images are input into the facial recognition speed measurement model to determine the pedestrian density and pedestrian speed in the area where the target vehicle is located. Based on the pedestrian density and pedestrian speed, the candidate warning sound level corresponding to the pedestrian information is determined.

[0099] In step S403, the vehicle control device 11 sends a request to the server 12 to obtain the warning sound setting parameters.

[0100] The alarm sound setting parameter acquisition request carries a user identifier.

[0101] In step S404, server 12 searches for the corresponding user-personalized alarm sound setting parameters based on the user identifier.

[0102] In step S405, server 12 sends the search result to vehicle control device 11.

[0103] Specifically, in response to the existence of the user-personalized warning sound setting parameter, the user-personalized warning sound setting parameter is sent to the target vehicle. In response to the absence of the user-personalized warning sound setting parameter, the latest version of the default warning sound setting parameter is sent to the target vehicle.

[0104] In step S406, the vehicle control device 11 determines the target warning sound setting parameters based on the search results.

[0105] The target warning sound setting parameters are preset parameters, and the target warning sound setting parameters include a mapping relationship between multiple warning sound levels and corresponding warning sound playback parameters.

[0106] It is worth noting that user-personally customized alert sound settings should be given priority as the target alert sound setting parameter. Specifically, it is determined whether user-personally customized alert sound settings exist. If user-personally customized alert sound settings exist, these settings are determined as the target alert sound setting parameter. If user-personally customized alert sound settings do not exist, the default alert sound setting parameter of the latest version is determined as the target alert sound setting parameter.

[0107] In one possible implementation, the vehicle control device 11 also pre-stores default warning sound setting parameters. If the information returned by the server cannot be received due to network reasons, the default warning sound setting parameters pre-stored by the vehicle control device 11 can be directly determined as the target warning sound setting parameters.

[0108] In step S407, the vehicle control device 11 determines the target warning sound playback parameters based on the target warning sound level and the target warning sound setting parameters.

[0109] The target warning sound playback parameters include warning sound type, warning sound volume, and / or warning sound playback frequency.

[0110] In step S408, the vehicle control device 11 controls the target vehicle to play the corresponding warning sound according to the target warning sound playback parameters.

[0111] In one possible implementation, server 12 interacts with vehicle control equipment via a network to determine the playback of a control warning sound.

[0112] Figure 5 This is an interactive flowchart of the alarm sound control method according to an embodiment of the present invention. Figure 5 As shown, the interaction flow of the warning sound control method includes the following steps:

[0113] In step S501, the vehicle control device 11 collects the driving information of the target vehicle.

[0114] In step S502, the vehicle control device 11 sends the driving information of the target vehicle to the server 12.

[0115] In step S503, server 12 determines the target warning sound level based on the speed information and the environmental information.

[0116] In step S504, server 12 searches for the corresponding user-personalized alarm sound setting parameters based on the user identifier.

[0117] In step S505, server 12 determines the target warning sound setting parameters based on the search results.

[0118] In step S506, the vehicle control device 11 of the server 12 determines the target warning sound playback parameters according to the target warning sound level and the target warning sound setting parameters.

[0119] In step S507, server 12 generates playback instructions.

[0120] The playback command includes the target warning sound playback parameters.

[0121] In step S508, server 12 sends a playback command to vehicle control device 11.

[0122] In step S509, the vehicle control device 11 controls the target vehicle to play the corresponding warning sound according to the target warning sound playback parameters.

[0123] The implementation logic of steps S501-S509 above is the same as that described above. Figure 4 The corresponding steps are the same, only the executing entity may be different. The specific implementation process will not be described in detail here.

[0124] In one possible approach, server 12 can also obtain alarm sound playback records and user feedback, and adjust the alarm sound setting strategy generation model based on the alarm sound playback records and / or user feedback. The alarm sound setting strategy generation model is used to generate alarm sound setting strategies, and the alarm sound setting strategies include multiple alarm sound setting parameter types and corresponding parameter selectable ranges.

[0125] The model for generating warning sound settings by periodically adjusting the warning sound settings strategy can make the range of selectable parameters provided by the model more consistent with actual vehicle driving conditions.

[0126] In one possible approach, the vehicle control device 11 or server 12 can also control the direction of the warning sound playback based on driving information.

[0127] Figure 6 This is a flowchart illustrating the warning sound playback direction determination method according to an embodiment of the present invention. Figure 6 As shown, the method for determining the direction of the warning sound playback includes the following steps:

[0128] Step S601: Determine the direction of the warning sound playback based on the driving direction and the moving direction of the movable obstacle.

[0129] Step S602: Determine the corresponding phased array speaker control information based on the direction of the warning sound playback.

[0130] Step S603: Control the speaker of the target vehicle to play a warning sound in the direction of the warning sound playback according to the phased array speaker control information.

[0131] The system of this invention acquires the driving information of the target vehicle, including speed and environmental information. Based on the driving information, it determines the target warning sound level and the target warning sound setting parameters. These parameters include a mapping relationship between multiple warning sound levels and corresponding warning sound playback parameters. Based on the target warning sound level and the target warning sound setting parameters, it determines the target warning sound playback parameters and controls the target vehicle to play the corresponding warning sound according to these parameters. Therefore, the system can automatically determine the warning sound playback effect based on the vehicle's driving status and surrounding environment, ensuring that the warning sounds played by the vehicle provide an appropriate warning effect in various environments and driving states. This reduces the need for user intervention, avoids improper or missed warning sounds, and improves the experience for vehicle users and nearby pedestrians.

[0132] Figure 7 This is a flowchart of an embodiment of the alarm sound control method of the present invention. As shown in Figure 7, the alarm sound control method includes the following steps:

[0133] Step S701: Obtain the driving information of the target vehicle, including speed information and environmental information.

[0134] Step S702: Determine the target warning sound level based on the speed information and the environmental information.

[0135] Step S703: Determine the target warning sound setting parameters. The target warning sound setting parameters are preset parameters, and the target warning sound setting parameters include a mapping relationship between multiple warning sound levels and corresponding warning sound playback parameters.

[0136] Step S704: Determine the target warning sound playback parameters based on the target warning sound level and the target warning sound setting parameters.

[0137] Step S705: Control the target vehicle to play the corresponding warning sound according to the target warning sound playback parameters.

[0138] For details of steps S701-S705 above, please refer to the above embodiment description and corresponding drawings, and they will not be repeated here.

[0139] The method of this invention involves acquiring the driving information of a target vehicle, including speed and environmental information; determining the target warning sound level based on the driving information; determining the target warning sound setting parameters, which include a mapping relationship between multiple warning sound levels and corresponding warning sound playback parameters; determining the target warning sound playback parameters based on the target warning sound level and the target warning sound setting parameters; and controlling the target vehicle to play the corresponding warning sound according to the target warning sound playback parameters. Therefore, the playback effect of the warning sound can be automatically determined based on the vehicle's driving status and surrounding environment, ensuring that the warning sound played by the vehicle provides an appropriate warning effect in various environments and driving states. This reduces the need for user intervention, avoids improper or missed warning sound usage, and improves the experience for vehicle users and nearby pedestrians.

[0140] Figure 8 This is a flowchart of an alarm sound control method for servers according to an embodiment of the present invention. As shown in Figure 8, the alarm sound control method for servers includes the following steps:

[0141] Step S801: Receive a request to obtain alarm sound setting parameters, wherein the alarm sound setting parameter acquisition request carries a user identifier.

[0142] Step S802: Locate the corresponding user-personalized alert sound setting parameters based on the user identifier.

[0143] Step S803: In response to the existence of the user-personalized warning sound setting parameters, send the user-personalized warning sound setting parameters to the target vehicle, so that the target vehicle determines the target warning sound playback parameters according to the user-personalized warning sound setting parameters and plays the warning sound according to the target warning sound playback parameters.

[0144] For details of steps S801-S803 above, please refer to the description of the above embodiments and the corresponding drawings, and they will not be repeated here.

[0145] The method of this invention, through interaction with the vehicle control device of the target vehicle, can send the user-personally customized warning sound setting parameters uploaded by the user terminal to the vehicle control device. This allows the target vehicle to determine the target warning sound playback parameters based on the user-personally customized warning sound setting parameters and play the warning sound according to the target warning sound playback parameters. This enables the vehicle control device to automatically determine the playback effect of the warning sound based on the vehicle's driving status and surrounding environment, ensuring that the warning sound played by the vehicle has an appropriate warning effect in various environments and driving states. This reduces the operation of the vehicle user, avoids improper use or omission of warning sounds, and improves the experience of vehicle users and nearby pedestrians.

[0146] Figure 9 This is a flowchart of a warning sound control method for a user terminal according to an embodiment of the present invention. As shown in Figure 9, the warning sound control method for a user terminal includes the following steps:

[0147] Step S901: Send an alert tone setting request to the server.

[0148] Step S902: Receive and display the alarm sound setting page returned by the server. The alarm sound setting page includes parameter acquisition controls and confirmation controls corresponding to multiple alarm sound setting parameter types. The parameter acquisition controls are used to receive parameters within the selectable range of parameters corresponding to the alarm sound setting parameter types.

[0149] Step S903: In response to the determination control being triggered, generate alert sound setting parameters for user personalization settings bound to the user identifier.

[0150] Step S904: Send the user-personalized alert sound setting parameters to the server.

[0151] Steps S901-S904 described above are detailed in the above embodiment description and corresponding drawings, and will not be repeated here.

[0152] The method of this invention interacts with a server to upload warning sound setting parameters that meet the user's personalized needs. The server saves these warning sound setting parameters so that when the user uses any vehicle, the system can determine the target warning sound playback parameters based on the user's pre-set warning sound settings, and then make the vehicle play the warning sound according to the target warning sound playback parameters. This achieves automatic determination of the warning sound playback effect based on the vehicle's driving status, surrounding environment, and the user's personalized settings, so that the warning sound played by the vehicle can play an appropriate warning effect in various environments and driving states. This reduces the user's operation, avoids improper or missed warning sound usage, and improves the experience of the user and nearby pedestrians.
