[0031] To enable those skilled in the art to better understand the present invention, the technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort should fall within the scope of protection of the present invention.

[0032] It should be noted that the terms "first," "second," etc., in the specification, claims, and accompanying drawings of this invention are used to distinguish similar objects and are not necessarily used to describe a specific order or sequence. It should be understood that such data can be interchanged where appropriate so that the embodiments of the invention described herein can be implemented in orders other than those illustrated or described herein. Furthermore, the terms "comprising" and "having," and any variations thereof, are intended to cover a non-exclusive inclusion; for example, a process, method, system, product, or apparatus that comprises a series of steps or units is not necessarily limited to those steps or units explicitly listed, but may include other steps or units not explicitly listed or inherent to such processes, methods, products, or apparatus.

[0033] Example 1

[0034] According to an embodiment of the present invention, an information output method embodiment is provided. It should be noted that the steps shown in the flowchart in the accompanying drawings can be executed in a computer system such as a set of computer-executable instructions. Furthermore, although a logical order is shown in the flowchart, in some cases, the steps shown or described may be executed in a different order than that shown here.

[0035] Figure 1 This is a flowchart illustrating an information output method according to an embodiment of the present invention, such as... Figure 1 As shown, the method includes the following steps:

[0036] Step S102: In response to the vehicle traveling to a preset environment, a broadcast signal sent by a preset device located in the preset environment is received.

[0037] Among them, the preset device is used to characterize the device carried by the preset object that affects the normal driving of the vehicle in the preset environment.

[0038] The aforementioned preset environment can refer to a complex environment that may affect the driver's normal driving, such as a scenic area or a highway environment. The aforementioned broadcast signal can refer to a signal transmitted by a preset device in the preset environment, which contains information related to an event currently occurring in the preset environment that will affect the normal driving of the vehicle. The aforementioned preset device can refer to a signal broadcasting device carried by a preset object included in the event.

[0039] To facilitate understanding, let's take a highway environment as an example. If some sections of the highway are damaged and require emergency repairs, there will be workers repairing the damaged sections. When a user drives a vehicle into the highway environment, the workers may be a pre-defined object that could affect the normal driving of the vehicle. To ensure the safety of the workers while they are repairing the road, a pre-defined device that can send broadcast signals can be installed on the workers. When the system detects that the workers have reached the section that needs repair and have started repairs, the device can be activated to broadcast the repair status of the section in real time.

[0040] It should be noted that the above example of workers repairing damaged road sections in a high-speed environment is only an illustrative example. The specific preset environment, preset objects, and preset equipment can be determined according to the actual situation and are not limited here.

[0041] In one optional embodiment, when a user drives a vehicle into a preset environment, in order to ensure driving safety, the information output system can receive broadcast signals from the preset environment in real time, so that the driver can promptly detect events in the preset environment that may affect the normal driving and driving safety of the vehicle, thereby improving the safety of the vehicle when driving in the preset environment.

[0042] In one optional embodiment, considering that other types of signals may exist in the preset environment, such as scenic spot introduction signals in a scenic environment and location positioning signals in a high-speed environment, and that these signals have little impact on the normal driving of the vehicle, the signal output system can ignore these signals when receiving broadcast signals and allocate a larger weight to receiving broadcast signals that may affect the normal driving of the vehicle.

[0043] Step S104: In response to receiving a broadcast signal, determine the target area from a preset environment based on the broadcast signal.

[0044] The target area is used to characterize the area where the preset device is located.

[0045] In one optional embodiment, after receiving a broadcast signal in a preset environment, the signal output system can determine the target area where the preset device is located from the preset environment based on the information contained in the broadcast signal, that is, the area in the preset environment that may affect the normal driving of the vehicle.

[0046] Step S106: Control the vehicle to output the area information of the target area.

[0047] The aforementioned regional information can refer to information that reflects the current situation of events occurring in the target area, including but not limited to the location of the target area, the scope of the target area, the type of event, and the degree of impact on the normal driving of vehicles.

[0048] In one optional embodiment, after the target area is determined, the information output system can output the aforementioned area information on the vehicle based on the information about the target area contained in the broadcast signal, thereby ensuring that the user can promptly discover areas in the preset environment that may affect the normal driving of the vehicle, thus enabling the user to focus on driving the vehicle and improving the safety of the vehicle driving process.

[0049] In this embodiment of the invention, a method is adopted in which, in response to a vehicle traveling to a preset environment, a broadcast signal sent by a preset device located in the preset environment is received; in response to receiving the broadcast signal, a target area is determined from the preset environment based on the broadcast signal; and the vehicle is controlled to output the area information of the target area. By determining the target area that may affect the normal driving of the vehicle from the preset environment based on the received broadcast signal containing information related to events currently occurring in the preset environment that may affect the normal driving of the vehicle, and controlling the vehicle to output the area information of the target area, the user can promptly discover potential risks in the preset environment that may affect the driving safety of the vehicle, thereby improving the user's driving safety and solving the technical problem of low vehicle safety in complex environments in related technologies.

[0050] Optionally, receiving broadcast signals sent by preset devices located in a preset environment includes: receiving multiple first broadcast signals in the preset environment; obtaining device identifiers of multiple first broadcast devices based on the multiple first broadcast signals; and filtering broadcast signals from the multiple first broadcast signals based on the device identifiers and the environment type of the preset environment.

[0051] The aforementioned first broadcast signal can refer to all signals present in the preset environment. In addition to the broadcast signal containing relevant information about the target area, it can also include other types of signals mentioned above, such as scenic spot introduction signals in scenic areas and location positioning signals in high-speed environments.

[0052] In one optional embodiment, to improve the recognizability of the broadcast signal, a specific device identifier can be configured on the preset device, enabling the information output system to accurately detect the broadcast signal sent by the preset device. However, considering that the device identifiers configured on different preset devices may differ, the signal output system may obtain the broadcast signal sent by each preset device with a specific device identifier individually, which could lead to low acquisition efficiency. Furthermore, the signal output system may not receive the broadcast signal when it is being sent because the preset device is outside the propagation range of the broadcast signal. Therefore, to avoid missing broadcast signals, the signal output system can receive multiple first broadcast signals in the preset environment in real time, and then determine the corresponding multiple first broadcast devices based on the multiple first broadcast signals, while simultaneously acquiring the device identifiers of the multiple first broadcast devices.

[0053] In one optional embodiment, different device identifiers for broadcasting equipment can be set for different types of preset environments. For example, in a scenic area, where vehicles travel at slower speeds, drivers are more likely to encounter events on the road that could affect normal vehicle operation. Therefore, broadcasting equipment with a smaller transmission range and longer transmission duration can be configured for the scenic area, and a corresponding scenic area device identifier can be set. In a high-speed environment, where vehicles travel at faster speeds, drivers may not be able to make the correct driving strategy in time to events appearing in front of the vehicle. Therefore, broadcasting equipment with a larger transmission range and longer transmission duration can be configured for the high-speed environment, and a corresponding high-speed device identifier can be set.

[0054] Therefore, after obtaining the device identifiers of multiple first devices, the information output system can further obtain the environment type of the preset environment, and determine the target broadcasting device from the multiple first broadcasting devices based on the environment type and device identifier, and then determine the broadcast signal sent by the target broadcasting device as the aforementioned broadcast signal.

[0055] In one optional embodiment, considering that events that affect the normal operation of a vehicle in a preset environment may also be caused by the user, the device used to transmit the broadcast signal may not be managed by the management device in the preset environment, but may be selected by the user. Therefore, in order to ensure that the device identifier of the broadcast device selected by the user matches the preset environment, thereby ensuring the user's safety in the event, the information output system can also configure the broadcast device with a device identifier that matches the environment type of the preset environment in real time when transmitting the broadcast signal, or select the broadcast device with a device identifier that matches the environment type from multiple broadcast devices, so that other users can promptly discover the above-mentioned events that affect the normal operation of the vehicle based on the environment type of the preset environment.

[0056] Optionally, based on the device identifier and the environment type of the preset environment, a broadcast signal is selected from multiple first broadcast signals, including: determining a broadcast identifier that matches the environment type from a preset identifier library, wherein the preset identifier library is used to characterize the mapping relationship between the environment type and the broadcast identifier of the broadcast device in the preset environment; matching the broadcast identifier and the device identifier to obtain an identifier matching result; determining a preset device from multiple first broadcast devices based on the identifier matching result; and determining the signal sent by the preset device as a broadcast signal.

[0057] The aforementioned preset identifier library stores the mapping relationship between the environment type of the preset environment and the broadcast identifier of the broadcasting device. Staff can pre-configure the corresponding device identifier for a specified type of preset environment to construct the aforementioned preset identifier library.

[0058] When selecting the desired broadcast signal from multiple first broadcast signals, the signal output system can first retrieve the aforementioned preset identifier library, and then select broadcast identifiers that match the environment type of the preset environment from the preset identifier library. Finally, the selected broadcast identifiers are matched with the device identifiers of multiple first broadcast devices to obtain the corresponding matching results.

[0059] As mentioned above, considering that the device identifier actually configured in the preset environment may be configured by the information output system or the user according to the environment type of the preset environment, there may be a small difference between it and the broadcast identifier in the preset identifier library. Therefore, when matching the device identifier and the broadcast identifier, the correlation between the broadcast identifier and the device identifier can be calculated, and the preset device can be determined from the first broadcast device based on the correlation. At the same time, the signal sent by the preset device is determined as the aforementioned broadcast signal.

[0060] Optionally, determining the target area from a preset environment based on the broadcast signal includes: determining the device location of a preset device based on the broadcast signal; obtaining the area status of a first area corresponding to the device location through an environmental database, wherein the environmental database is used to characterize a database composed of area statuses of multiple areas in the preset environment; determining the influence level of the first area based on the area status and the vehicle's driving parameters, wherein the influence level is used to characterize the degree to which the first area affects the normal driving of the vehicle; and determining the first area as the target area in response to the influence level meeting a preset level condition.

[0061] The aforementioned environmental database refers to a database composed of the real-time regional status of different areas within a preset environment, obtained from management devices in those areas. Vehicles can connect to this database via an environmental network set up within the preset environment. Considering the potential for poor connection stability between the vehicle and the environmental network during operation, the connection can be controlled only when there is a need to obtain environmental status information.

[0062] In one optional embodiment, considering that the area where the broadcasting equipment is located may affect the normal driving of the vehicle, but some areas may have a negligible impact on the normal driving of the vehicle, the information output system can first determine the device location of the preset device in the preset environment based on the received broadcast signal, and simultaneously connect the vehicle network to the aforementioned environmental network. It can then obtain the regional state of the first region corresponding to the device location from the environmental database. Based on this regional state and the vehicle's current driving parameters, such as driving speed and trajectory, it can determine whether an event occurring in the first region will affect the normal driving of the vehicle, and the corresponding level of impact. For example, it can determine whether the vehicle's trajectory intersects with the first region to determine whether the event will affect the normal driving of the vehicle. Then, based on the distance from the vehicle's current location to the first region and the vehicle's current driving speed, it can determine the level of impact of the first region on the normal driving of the vehicle.

[0063] Finally, if the determined impact level meets the preset level conditions, such as the impact level being greater than the preset level threshold, then the first region can be determined as the aforementioned target region. In an optional embodiment, if the broadcast signal contains a region range, then that region range can also be used as the range of the aforementioned target region, further determining the target region from the first region, thereby improving the accuracy of the determined target region.

[0064] Optionally, the method further includes: in response to the influence level not meeting the preset level condition, obtaining the current driving trajectory of the vehicle; adjusting the regional trajectory segment in the driving trajectory based on the object characteristics of the preset object to obtain the target driving trajectory, wherein the regional trajectory segment is used to characterize the trajectory segment in the driving trajectory that matches the device position; and controlling the vehicle driving based on the target driving trajectory.

[0065] The object characteristics of the aforementioned preset object can refer to the type, size, possible range of influence, and possible time of influence of the preset object. The aforementioned area trajectory segment can refer to the trajectory segment in the vehicle's driving trajectory that matches the area where the preset object corresponding to the preset device is located. This trajectory segment can be determined by the object characteristics of the preset object.

[0066] In one optional embodiment, if the determined impact level does not meet the preset level conditions, it means that the vehicle can currently drive normally through the first area. The information output system can further obtain the current driving trajectory of the vehicle and adjust the above-mentioned area trajectory segment according to the object characteristics of the preset object to determine the target driving trajectory that will not affect the normal driving of the vehicle and will not change the general driving trajectory of the vehicle. Finally, the vehicle driving is controlled by the target driving trajectory to ensure the safety of the vehicle driving.

[0067] Optionally, controlling the vehicle to output area information of the target area includes: obtaining the object type of a preset object; determining the target output method based on the object type and the area status of the target area; determining the target output frequency based on the influence level of the target area; and controlling the vehicle to output area information based on the target output method and the target output frequency.

[0068] In one optional embodiment, when outputting area information, the information output system can also obtain the object type of a preset object and determine the specific target output method based on the object type and the area status of the target area. For example, if the object type indicates that the preset object is a road maintenance worker, and the area status indicates that the target area is severely congested and unsuitable for travel, then to ensure the safety of the maintenance worker, a more prominent output method, such as voice broadcasting, can be selected as the target output method. If the object type indicates that the preset object is another vehicle, and the area status indicates that the target area is relatively clear and the area affected by other vehicles is small, then a common output method, such as light prompts or text display, can be selected as the target output method. Simultaneously, the corresponding target output frequency can be determined based on the aforementioned determined impact level of the target area. For example, the higher the impact level, the higher the corresponding target output frequency; the lower the impact level, the lower the corresponding target output frequency. Finally, after determining the target output method and target output frequency, the information output system can use these target output methods and frequencies to control the vehicle to output the area information of the target area.

[0069] Optionally, the method further includes: obtaining the vehicle's driving position and the sensing position of the sensing device, wherein the sensing device is deployed at the boundary of a preset environment; in response to the distance from the driving position to the sensing position being less than a preset distance, obtaining the device status of the sensing device within a preset time period; in response to the device status switching within the preset time period, determining that the vehicle has driven to the preset environment; in response to the device status not switching within the preset time period, determining that the vehicle has not driven to the preset environment.

[0070] In one optional embodiment, the vehicle's position and sensing devices deployed on the boundary of the preset environment can also be used to determine whether the vehicle has entered the preset environment. Specifically, the information output system can acquire in real time the sensing signals near the vehicle, the vehicle's current position, and the sensing position of the sensing devices used to send the sensing signals. If the distance between the vehicle's current position and the sensing position is less than a preset distance, the information output system can further acquire the device status of the sensing devices. If the device status of the sensing devices changes within a preset time period, and the received sensing signal indicates that the object entering the preset environment is a vehicle, and the vehicle characteristics match the characteristics of the user's vehicle, then it can be determined that the vehicle has entered the preset environment. If the device status of the sensing devices does not change within the preset time period, or the vehicle characteristics do not match the characteristics of the user's vehicle, then it can be determined that the vehicle has not entered the preset environment.

[0071] It should be noted that the above method for determining whether a vehicle has entered a preset environment is only an example. The specific method for determining whether a vehicle has entered a preset environment can be determined according to the actual situation and is not limited here. For example, if the satellite positioning signal is good, the vehicle's position can also be directly determined through the satellite positioning system to determine whether the vehicle has entered the preset environment.

[0072] Optionally, the method further includes: in response to a vehicle malfunction occurring in a preset environment, determining the malfunction type; determining the vehicle malfunction level based on the malfunction type and the environment type of the preset environment, wherein the malfunction level is used to characterize the degree to which the vehicle affects the normal operation of other vehicles; and controlling the broadcasting equipment on the vehicle to send a broadcast signal based on the malfunction level.

[0073] In one optional embodiment, if a user's vehicle malfunctions and cannot continue driving in a preset environment, the information output system can determine the fault type to ensure the safety of other users and enable them to promptly detect the fault. Based on the fault type and the preset environment type, the system constructs the aforementioned broadcast signal, selects a broadcast device with a device identifier matching the environment type, and determines the degree to which the fault affects the normal driving of other vehicles, i.e., the fault level. Finally, based on the fault level, such as the determined broadcast device on the vehicle, the system sends the broadcast signal. For example, if the fault level is high, a larger broadcast range and frequency can be set to send the broadcast signal; if the fault level is low, a smaller broadcast range and frequency can be set to send the broadcast signal.

[0074] To facilitate understanding, the above process will be explained below using the preset environment of a high-speed environment and the preset object of road maintenance personnel as an example. Figure 2 This is a schematic diagram illustrating a road information output process according to an embodiment of the present invention, such as... Figure 2 As shown, to ensure the safety of workers maintaining roads, each worker can be equipped with a portable OBU (On-Board Unit), i.e., a pre-installed device. When the portable OBU is in the active state, it can transmit broadcast signals in real time. These broadcast signals can include at least the worker's work status, work location, and device identification information. When the vehicle is traveling in a high-speed environment, it can use DSRC (Deticated Short Range Communication) technology to receive broadcast signals from the high-speed environment in real time using the on-board OBU. After successfully receiving the broadcast signal, it can determine whether the area information of the worker's location has been output to the user within a preset time period. If it has been output, the area information does not need to be broadcast; otherwise, the area information can be broadcast.

[0075] For ease of understanding, Figure 3 This is a schematic diagram illustrating a high-speed environmental information receiving method according to an embodiment of the present invention. In this diagram, A represents road maintenance workers, B represents the broadcast range of a portable OBU device carried by the workers, C represents the highway the vehicle is currently traveling on, D represents another highway, 1 and 2 represent other vehicles on highway C, and 3 represents other vehicles on highway D. Figure 3 As shown, the portable OBU device carried by the staff can send broadcast signals within a preset range, typically 1 km, when the staff is maintaining the road. When a vehicle enters the broadcast range, the OBU device on the vehicle can receive the broadcast signal. At this time, the vehicle's information output system can determine whether the staff will affect the normal operation of the vehicle based on the received broadcast signal. For example... Figure 3 Vehicle 1 will be affected by the staff, while vehicles 2 and 3 will not. Therefore, the information output system of vehicle 1 can further determine the target area where the staff is located and control the vehicle to output the area information of the target area, so that the user of vehicle 1 can know in time that there are staff maintaining the road ahead of the vehicle, and thus the user can make the correct driving operation in time.

[0076] Figure 4This is a schematic diagram of a portable OBU device according to an embodiment of the present invention.
