Description

Technical Field

[0001] This application relates to the field of computer technology, and in particular to a method, apparatus, device and computer-readable storage medium for outputting prompt sounds. Background Technology

[0002] Because existing new energy vehicles have no engine noise, they produce very low noise when starting or driving at low speeds, so they play low-speed warning sounds to alert pedestrians. In addition, medium and large vehicles (such as light trucks, heavy trucks, and buses) typically play reversing warning sounds and turn signal sounds to alert pedestrians due to blind spots, ensuring pedestrian safety.

[0003] However, due to differences in their overall vehicle architecture, light trucks, mini-trucks, minivans, heavy trucks, and buses follow different bus protocols and have inconsistent communication protocols. This necessitates the development and design of unique alert tone systems for each vehicle model, and these systems can only produce one alert tone, supporting only a single vehicle platform. In other words, existing alert tone output methods have poor universality. Summary of the Invention

[0060] The realization of the purpose, functional features and advantages of this application will be further explained in conjunction with the embodiments and with reference to the accompanying drawings. Detailed Implementation

[0061] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0062] In this article, the term "and / or" is merely a description of the relationship between related objects, indicating that there can be three relationships. For example, A and / or B can represent three situations: A exists alone, A and B exist simultaneously, and B exists alone.

[0063] The terms "first" and "second," etc., used in the specification and claims of this application are used to distinguish different objects, not to describe a specific order of objects. For example, "first target object" and "second target object," etc., are used to distinguish different target objects, not to describe a specific order of target objects.

[0064] In the embodiments of this application, the words "exemplarily" or "for example" are used to indicate examples, illustrations, or explanations. Any embodiment or design described as "exemplarily" or "for example" in the embodiments of this application should not be construed as being more preferred or advantageous than other embodiments or design solutions. Specifically, the use of the words "exemplarily" or "for example" is intended to present the relevant concepts in a specific manner.

[0065] It should be understood that the specific embodiments described herein are merely illustrative of this application and are not intended to limit this application.

[0066] Please refer to Figure 1 , Figure 1 This is a flowchart illustrating the first embodiment of the prompt tone output method of this application. It should be noted that although the logical order is shown in the flowchart, in some cases, the steps shown or described may be performed in a different order than that shown here.

[0067] The first embodiment of this application provides a method for outputting a prompting sound, the method comprising the following steps:

[0068] Step S100: Receive the message information of the current vehicle;

[0069] In this embodiment, it should be noted that the execution subject of the prompt tone output method is a prompt tone output device, which can be an AVAS (Acoustic Vehicle Alerting System), a PC (Personal Computer), a tablet computer, a portable computer, or a server, etc. The application subject of the prompt tone output method in this embodiment is vehicles with prompt tone output requirements, such as pure electric vehicles, hybrid vehicles, and fuel vehicles.

[0070] In this embodiment, it should also be noted that the message information includes information such as current vehicle speed, current gear, and ready status (i.e., the vehicle is in a drivable state).

[0071] In this embodiment, after the vehicle is powered on, the vehicle controller, GW (gateway), BCM (Body Control Module), instrument cluster, and other controllers are activated. The vehicle controller then periodically forwards messages such as gear position signals, vehicle speed signals, and ready signals through the gateway to the prompt tone output device, thereby enabling the reception of message information from the current vehicle.

[0072] Step S200: Identify the message information to determine the vehicle type of the current vehicle;

[0073] In this embodiment, it should be noted that the vehicle type can be a conventionally classified type such as light truck, mini truck, mini van, heavy truck, or bus, or it can be a vehicle type classified according to specific user needs, such as Class I vehicle, Class II vehicle, or Class III vehicle.

[0074] As an example, this embodiment can identify the data frame of the message information. By identifying the field corresponding to the vehicle type in the frame header or frame tail of the data frame, the code of the field corresponding to the vehicle type is read to obtain the target vehicle model code. Then, based on the target vehicle model code, the vehicle type of the current vehicle can be determined according to the preset correspondence between vehicle model codes and vehicle types.

[0075] As another example, since the vehicle steering information in the message is sent to the prompt tone output device by another controller, rather than by the vehicle controller, and different vehicles use different controllers to send the vehicle steering information, the source of the vehicle steering information in the message can be identified to obtain the signal source controller. Then, based on the correspondence between the signal source controller and the vehicle type, the vehicle type of the current vehicle can be determined.

[0076] The step S200, which involves identifying the message information and determining the vehicle type of the current vehicle, includes:

[0077] Step S210: Identify the data frame of the message information to obtain the target vehicle model code;

[0078] Step S220: Determine the vehicle type of the current vehicle based on the target vehicle model code.

[0079] In this embodiment, it should be noted that the frame header or frame tail of the data frame contains a field corresponding to the vehicle type.

[0080] This embodiment can identify the data frames of the message information. By identifying the field corresponding to the vehicle type in the frame header or frame tail of the data frame, the target vehicle model code is obtained by reading the code of the field corresponding to the vehicle type. Then, based on the target vehicle model code, the vehicle type of the current vehicle can be determined according to the preset correspondence between vehicle model codes and vehicle types. For example, the preset correspondence between vehicle model codes and vehicle types can be described in the form of a mapping table. The vehicle type of the current vehicle can then be obtained by querying the preset vehicle model code and vehicle type mapping table based on the target vehicle model code. This embodiment conveniently and quickly realizes the identification of the vehicle type of the current vehicle.

[0081] Step S300: parse the message information based on the bus protocol corresponding to the vehicle type, and control the current vehicle to output a prompt tone based on the parsed message information.

[0082] In this embodiment, there is a correspondence between the vehicle type and the bus protocol. Therefore, the bus protocol corresponding to the vehicle type can be queried by establishing this correspondence. For example, the bus protocol can be the SAE J1939 protocol or the ISO 11898 protocol. In this embodiment, the message information can be parsed using the bus protocol corresponding to the vehicle type to obtain the data portion of the data frame of the message information. Then, based on the parsed message information and preset prompt tone output conditions, it can be determined whether the current vehicle meets the preset prompt tone output conditions. If the current vehicle meets the preset prompt tone output conditions, the current vehicle can be controlled to output a prompt tone. If the current vehicle does not meet the preset prompt tone output conditions, the following step is executed: determine whether the current vehicle meets the preset prompt tone output conditions. The preset prompt tone output conditions are pre-set conditions for outputting prompt tones, such as the current vehicle being in a low-speed driving state, a reversing state, or a target turning state. It is understood that the prompt tone can be one or more prompt tones, such as a low-speed prompt tone, a reversing prompt tone, a turning prompt tone, etc.

[0083] The step S300, which involves controlling the current vehicle to output a prompt tone based on the parsed message information, includes:

[0084] Step S310: Based on the parsed message information, determine whether the current vehicle is in a low-speed driving state;

[0085] Step S320: If the current vehicle is in a low-speed driving state, control the current vehicle to output a low-speed warning sound.

[0086] In this embodiment, it should be noted that the parsed message information may include the current vehicle speed, current gear, and ready status.

[0087] This embodiment can determine whether the current vehicle speed is within a preset low-speed range, whether the current gear is a non-parking gear, and whether the ready state is "ready" based on the parsed message information, to determine whether the current vehicle is in a low-speed driving state. If the current vehicle speed is within the preset low-speed range, the current gear is a non-parking gear, and the ready state is "ready," then the current vehicle is determined to be in a low-speed driving state. If the current vehicle speed is not within the preset low-speed range, or the current gear is not a non-parking gear, or the ready state is not "ready," then the current vehicle is determined not to be in a low-speed driving state. If the current vehicle is in a low-speed driving state, then the current vehicle is controlled to output a low-speed warning sound. If the current vehicle is not in a low-speed driving state, then the following step is executed: determine whether the current vehicle is in a low-speed driving state based on the parsed message information. The preset low-speed range is a pre-set speed range for low-speed vehicle driving, such as a speed greater than 1 km / h and less than 21 km / h. The non-parking gear refers to any gear other than parking, such as drive, reverse, or neutral. This embodiment outputs a low-speed warning sound for vehicles traveling at low speeds, preventing pedestrians from failing to notice the vehicle when it starts or travels at low speeds.

[0088] The step S300, which involves controlling the current vehicle to output a prompt tone based on the parsed message information, further includes:

[0089] Step S330: Based on the parsed message information, determine whether the current vehicle is in a reversing state;

[0090] Step S340: If the current vehicle is in reverse, control the current vehicle to output a reversing warning sound.

[0091] This embodiment can determine whether the current gear is reverse and whether the ready state is "ready" based on the parsed message information, thus determining whether the current vehicle is in reverse. If the current gear is reverse and the ready state is "ready," then the current vehicle is determined to be in reverse. If the current gear is not reverse or the ready state is not "ready," then the current vehicle is determined not to be in reverse. If the current vehicle is in reverse, then the current vehicle is controlled to output a reversing warning sound. If the current vehicle is not in reverse, then the step of determining whether the current vehicle is in reverse based on the parsed message information is executed. This embodiment implements the output of a reversing warning sound for vehicles in reverse, preventing pedestrians behind the current vehicle from failing to notice that the vehicle is reversing.

[0092] In the first embodiment of this application, message information from the current vehicle is received; the message information is identified to determine the vehicle type of the current vehicle; the message information is parsed based on the bus protocol corresponding to the vehicle type; and the current vehicle is controlled to output a prompt tone based on the parsed message information. Thus, this application integrates different bus protocols, identifies the current vehicle's message information to determine its vehicle type, and adapts the parsing of the message information to the bus protocol corresponding to the vehicle type to control the current vehicle to output a prompt tone. Therefore, the prompt tone output method of this application can adapt to the prompt tone output requirements of different vehicle types, and is not only applicable to low-speed prompt tone output but also compatible with reversing and turning prompt tone outputs, effectively improving the universality of prompt tone output.

[0093] Reference Figure 2 , Figure 2 This is a flowchart illustrating a second embodiment of the prompt sound output method of this application.

[0094] In another embodiment of this application, content that is the same as or similar to the above embodiments can be referred to the above description, and will not be repeated hereafter. A second embodiment of this application provides a prompt sound output method, wherein the message information includes vehicle turning information. The step S200, which involves identifying the message information and determining the vehicle type of the current vehicle, further includes:

[0095] Step S230: Identify the source of the vehicle steering information and obtain the signal source controller;

[0096] Step S240: According to the signal source controller, query the preset vehicle type mapping table to obtain the vehicle type of the current vehicle.

[0097] In this embodiment, it should be noted that the message information includes vehicle turning information, which includes at least turn signal signals, and may also include position light signals and hazard warning light signals, etc.

[0098] Since the vehicle steering information in the message is sent to the prompt tone output device by another controller, rather than by the vehicle controller, and different vehicles use different controllers to send the vehicle steering information, this embodiment can identify the source of the vehicle steering information and obtain the signal source controller. It can be understood that the signal source controller is the controller within the current vehicle that sends the vehicle steering information to the prompt tone output device, such as an IC (Instrument Cluster) or BCM (Body Control Module). Then, based on the signal source controller, a preset vehicle type mapping table can be consulted to obtain the vehicle type of the current vehicle. The preset vehicle type mapping table is a pre-set mapping table used to describe the correspondence between the signal source controller and the vehicle type.

[0099] The step S300, which involves controlling the current vehicle to output a prompt tone based on the parsed message information, further includes:

[0100] Step S350: Based on the parsed vehicle steering information, determine whether the current vehicle is in the target steering state;

[0101] Step S360: If the current vehicle is in the target turning state, control the current vehicle to output a turning prompt sound.

[0102] In this embodiment, it should be noted that the target turning state is the state in which the current vehicle turns in a target direction, which is the direction opposite to the position of the driver's seat of the current vehicle. For example, if the current vehicle is a left-hand drive vehicle (i.e., the driver's seat is on the left side of the vehicle), the corresponding target turning state is a right turn. If the current vehicle is a right-hand drive vehicle (i.e., the driver's seat is on the right side of the vehicle), the corresponding target turning state is a left turn. The parsed vehicle turning information includes at least the current turn signal status.

[0103] In this embodiment, based on the parsed vehicle turning information, it can determine whether the current vehicle speed is greater than a preset minimum speed (e.g., 1 km / h, 2 km / h, 3 km / h, etc.) and whether the current turn signal is illuminated in the target direction, to determine whether the current vehicle is in a target turning state. If the current vehicle speed is greater than the preset minimum speed and the current turn signal is illuminated in the target direction, then the current vehicle is determined to be in a target turning state. If the current vehicle speed is not greater than the preset minimum speed, or the current turn signal is not illuminated in the target direction, then the current vehicle is determined not to be in a target turning state. If the current vehicle is in a target turning state, it is controlled to output a turning prompt sound. If the current vehicle is not in a target turning state, the following step is executed: based on the parsed vehicle turning information, determine whether the current vehicle is in a target turning state. This embodiment implements the output of a turning prompt sound for vehicles in a target turning state, preventing pedestrians from noticing the vehicle's turn when in the vehicle's blind spot.

[0104] In the second embodiment of this application, a signal source controller is obtained by identifying the source of the vehicle steering information. Then, based on the signal source controller, a preset vehicle type mapping table is queried to obtain the vehicle type of the current vehicle. This method is more convenient than methods that require identifying the frame header or frame tail of the message information, and it improves the efficiency of identifying the vehicle type of the current vehicle.

[0105] Reference Figure 3 , Figure 3 This is a flowchart illustrating the third embodiment of the prompt sound output method of this application.

[0106] In another embodiment of this application, content that is the same as or similar to the above embodiments can be referred to the above description, and will not be repeated hereafter. A third embodiment of this application provides a method for outputting a prompt tone. The step S300, which involves controlling the current vehicle to output a prompt tone based on the parsed message information, includes:

[0107] Step A10: Based on the vehicle type, query the preset volume mapping table to obtain the target volume;

[0108] Step A20: Based on the parsed message information, control the current vehicle to output a prompt tone according to the target volume.

[0109] In this embodiment, it should be noted that the preset volume mapping table is a pre-set mapping table used to describe the correspondence between vehicle type and volume.

[0110] Because different vehicle models have different dimensions, the installation positions of the sound-generating devices used to output alert tones also differ. Using the same volume level would make it difficult to adapt the sound output to the needs of users of different vehicle models. Therefore, this embodiment can query a preset volume mapping table based on the vehicle type to obtain the target volume. Then, based on the parsed message information, the current vehicle can be controlled to output an alert tone at the target volume.

[0111] In the third embodiment of this application, the target volume is obtained by querying a preset volume mapping table according to the vehicle type; based on the parsed message information, the current vehicle is controlled to output a prompt tone according to the target volume. Therefore, this embodiment ensures that the target volume of the prompt tone matches different vehicle types, meeting the sound effect needs of users with different vehicle types.

[0112] See Figure 4 , Figure 4 This is a schematic diagram of a scenario involved in the embodiments of this application.

[0113] like Figure 4 As shown, this embodiment uses an acoustic car alarm system as an example of the prompt tone output device. After the current vehicle is powered on, the vehicle controller, gateway, body control module, instrument panel, anti-lock braking system, and acoustic car alarm system are all activated. The vehicle controller then periodically forwards message information such as gear position signal, vehicle speed signal, and ready signal to the acoustic car alarm system through the gateway, allowing the acoustic car alarm system to receive the message information from the current vehicle. The acoustic car alarm system can identify the data frames in the message information. By identifying the field corresponding to the vehicle type in the frame header or frame tail of the data frame, it reads the code of the field corresponding to the vehicle type to obtain the target vehicle model code. Then, based on the preset correspondence between vehicle model codes and vehicle types, it determines the vehicle type of the current vehicle based on the target vehicle model code. Furthermore, the message information also includes vehicle steering information. Since the vehicle steering information in the message information is sent to the acoustic car alarm system by other controllers, rather than by the vehicle controller, this information is not sent directly from the vehicle controller. Different vehicles use different controllers to send the vehicle steering information. Therefore, the source of the vehicle steering information in the message can be identified to obtain the signal source controller, such as... Figure 4As shown, controllers such as the instrument cluster and body control module can directly or via a gateway send vehicle turning information, such as turn signal signals, position light signals, and hazard warning light signals, to the acoustic vehicle alarm system. Then, based on the correspondence between the signal source controller and the vehicle type, the vehicle type can be determined. For example, if the signal source controller is the instrument cluster, the vehicle type can be determined to be a passenger vehicle; if the signal source controller is the body control module, the vehicle type can be determined to be a heavy truck.

[0114] See Figure 5 , Figure 5 This is a schematic diagram of the prompt tone output device of this application.

[0115] like Figure 5 As shown, this application provides a prompt tone output device, applied to a prompt tone output equipment, the prompt tone output device comprising:

[0117] The identification module 20 is used to identify the message information and determine the vehicle type of the current vehicle;

[0130] The source of the vehicle steering information is identified to obtain the signal source controller;

[0131] The vehicle type of the current vehicle is obtained by querying a preset vehicle type mapping table based on the signal source controller.

Compared with the prior art, the beneficial effects of the prompt tone output device provided in this application are the same as those of the prompt tone output methods provided in the above embodiments, and other technical features in this prompt tone output device are the same as those disclosed in the methods of the above embodiments, and will not be repeated here.

The memory 1005 may be a high-speed random access memory (RAM) or a stable non-volatile memory (NVM), such as a disk drive. Alternatively, the memory 1005 may be a storage device independent of the aforementioned processor 1001.
