[0002] In virtual driving scenarios, various control parameters are preset for different scenarios to control the vehicle's movement.

[0003] However, in actual driving, factors such as vehicle speed and road conditions can affect tire condition. For example, excessive speed or rough road surfaces can cause a tire blowout, leading to a car accident. Users may not be able to quickly perceive tire damage, nor may they possess first-aid knowledge. Therefore, virtual driving scenarios need to simulate tire blowouts and train users to master the correct procedures for handling a tire blowout. Summary of the Invention

[0033] Generate and output a first prompt message through the input / output module. The first prompt message is used to instruct the target vehicle to drive to the nearest service area of ​​the target vehicle according to the target safe parking navigation guide.

[0034] If no confirmation operation from the user is received regarding the target safe parking navigation guidance within the second time period, the second speed of the target vehicle is obtained in real time through the input / output module.

[0035] If the second vehicle speed is greater than the second threshold and the second duration is greater than the second preset duration, then it is determined that the tires of the target vehicle meet the preset tire blowout conditions; wherein, the second duration is the duration during which the second vehicle speed is higher than the second threshold, the first duration is less than the second duration, the first preset duration is less than the second preset duration, and the first threshold is less than the second threshold.

[0036] The location of the damaged tire of the target vehicle is obtained, and a second prompt message is generated and output through the input / output module based on the location of the damaged tire.

[0050] Compared to existing technologies, the solution provided in this application, after determining that the target vehicle's current tire pressure meets a preset abnormal tire pressure condition based on the target vehicle's first speed and duration, outputs a first prompt message instructing the target vehicle to drive to the nearest service area according to the target safe parking navigation guide.

Furthermore, the modules or sub-modules described as separate components may or may not be physically separate, may or may not be physical modules, or may be distributed among multiple circuit modules. Some or all of the modules may be selected according to actual needs to achieve the purpose of the embodiments of this application.

[0055] The following combination Figures 1-3 The technical solutions of the embodiments of this application will be described by way of example.

[0056] See Figure 1A vehicle balance control method in a virtual driving scenario is provided. This method can be applied to a virtual driving control system, which includes a simulator (i.e., a virtual controller), a vehicle perception model, and a driving scenario simulation platform. The simulator generates driving commands for the target vehicle. The driving scenario simulation platform includes a first area and a second area. The first area displays multiple driving modes, each including at least two road segment materials. The second area currently displays dynamic images under a tire blowout prevention driving mode. These dynamic images include the target vehicle in motion and at least two service areas corresponding to the tire blowout prevention driving mode. The dynamic images and trajectory data of the target vehicle in the second area are transmitted to the vehicle perception model via a port. This method is executed by the simulator. Embodiments of this application include:

[0057] 101. Real-time acquisition of the target vehicle's first speed in the tire blowout prevention driving mode.

[0058] 102. If the first vehicle speed is greater than the first threshold and the first duration is greater than the first preset duration, then it is determined that the current first vehicle tire pressure of the target vehicle meets the preset abnormal tire pressure condition.

[0059] The first duration refers to the duration during which the first vehicle speed is higher than the first threshold. For example, if the first vehicle speed is greater than 60 km / h and the duration is 2 seconds, then a tire pressure abnormality alert can be triggered, i.e., the following first alert message will be generated.

[0060] 103. Generate and output the first prompt message.

[0061] The first prompt message instructs the target vehicle to follow the target safe parking navigation guidance to the nearest service area. Specifically, the first prompt message prompts the user to control the target vehicle's speed, reduce or stop accelerator pedal operation, downshift, intermittently apply light braking, and perform minor rightward steering wheel maneuvers to ensure the target vehicle can safely reach the nearest service area despite abnormal tire pressure. This is especially important when the target vehicle is on slippery roads in rainy, foggy, or snowy conditions, where precise control of speed and steering wheel is crucial.

[0062] In some implementations, generating and outputting the first prompt message includes:

[0063] Obtain the current target location of the target vehicle;

[0064] Determine the set of nearby service areas within a preset range of the target location;

[0065] Select at least one target nearby service area from the set of nearby service areas whose current service status is idle or not busy;

[0066] Based on the target location, the at least one nearby service area, and the traffic conditions along the route from the target location to each nearby service area, multiple candidate safe parking navigation directions are generated.

[0067] Select the target safe parking navigation guide from multiple candidate safe parking navigation guides according to priority;

[0068] The first prompt message is generated and output based on the target safe parking navigation guide.

[0069] As can be seen, after determining the set of nearby service areas within the preset range based on the vehicle's current target location, the system further selects at least one target nearby service area by considering the service status of each nearby service area in the set. Then, based on the target location, these target nearby service areas, and the traffic conditions along the route from the target location to each target nearby service area, multiple candidate safe parking navigation guidelines are finally generated. Thus, the final target safe parking navigation guidelines comprehensively consider multiple dimensions, making them more scientific, accurate, and more in line with the current traffic conditions. They can effectively ensure that the target vehicle can safely and quickly drive to the target nearby service area for parking.

[0070] 104. If no confirmation operation from the user regarding the target safe parking navigation guidance is received within the second time period, the second speed of the target vehicle is obtained in real time.

[0071] If no confirmation from the user regarding the target safe parking navigation guidance is received within the second time period, it means that the user ignores the safe parking navigation guidance indicated in the first prompt message and continues driving, which may cause the tires of the target vehicle to deteriorate from an abnormal state to a worse state, such as a tire blowout. Therefore, in order to simulate the handling scheme from an abnormal tire pressure state to a tire blowout, the speed of the target vehicle is acquired in real time during the continued driving of the target vehicle, so that the tire condition of the target vehicle can be continuously monitored to see if it is about to or has already reached a tire blowout state.

[0072] 105. If the second vehicle speed is greater than the second threshold and the second duration is greater than the second preset duration, then it is determined that the tires of the target vehicle meet the preset tire blowout conditions.

[0073] Wherein, the second duration is the duration during which the second vehicle speed is higher than the second threshold, the first duration is less than the second duration, the first preset duration is less than the second preset duration, and the first threshold is less than the second threshold.

[0074] For example, if the second vehicle speed is greater than 80km / h and lasts for 3 seconds, a tire blowout warning can be triggered, generating the following second warning message.

[0075] 106. Obtain the location of the tire damage of the target vehicle, and generate and output a second prompt message based on the location of the tire damage.

[0076] The second prompt message is used to prompt the user to perform at least one of the following actions: release the accelerator pedal, downshift, shorten the braking distance, and turn the steering wheel within a preset angle, until the vehicle reaches any nearby service area.

[0077] In some implementations, generating and outputting a second notification message based on the location of tire damage includes:

[0078] Acquire prior knowledge of safe handling procedures in the event of a tire blowout;

[0079] Based on the prior knowledge of safety procedures, select at least one treatment operation that matches the location of the tire damage;

[0080] The second prompt message is generated and output based on the selected at least one processing operation.

[0081] Wherein, the prior knowledge of safety procedures corresponding to different tires of the target vehicle where the tire damage location is the same or different or overlaps.

[0082] As can be seen, because prior knowledge about safe handling of tire blowouts is pre-set, when a tire blowout occurs in the simulated tire blowout scenario, the system can quickly match the appropriate handling operation for the damaged tire. This allows for targeted emergency handling of the damaged tire, ensuring that the target vehicle can safely drive to the nearest service area and park, reducing the likelihood of improper operation leading to an inability to safely or timely reach the nearest service area.

[0083] In some implementations, both the first prompt message and the second prompt message satisfy at least one of the following:

[0084] This can be any type of prompt message in text, audio, or video;

[0085] Output via at least one of the following methods: SMS, instant messaging, email, telephone, or pop-up window.

[0086] Understandably, after prompting the user, if the target vehicle's speed is subsequently detected to be below the first threshold, the driving on the normal road segment will be automatically canceled, the vehicle will exit the abnormal road segment, and the trip will end and exit. After exiting, the vehicle perception model will collect the target vehicle's driving data, including mileage, driving time, error operation points, and driving footage. The vehicle perception model can analyze the effectiveness of each virtual driving training session based on this driving data to continuously adjust and conduct more comprehensive driving simulation tests. An error operation point refers to when the user accelerates the target vehicle on a slippery road segment; this acceleration operation needs to be recorded, and the user can replay the point where the timeout occurred, reminding them to drive at a low speed on slippery roads.

[0087] As can be seen, in this embodiment, after determining that the target vehicle's current first tire pressure meets the preset abnormal tire pressure condition based on the target vehicle's first speed and duration, a first prompt message is output to instruct the target vehicle to drive to the nearest service area according to the target safe parking navigation guide. If the user ignores this message, and if the target vehicle's tires meet the preset blowout condition based on the target vehicle's second speed and duration, a second prompt message is generated and output based on the tire damage location to prompt the user to perform at least one of the following actions: release the accelerator pedal, downshift, shorten the brake pedal stroke, and turn the steering wheel within a preset angle, until the vehicle reaches any nearby service area. On the one hand, because this target safe parking navigation guide comprehensively considers multiple factors, it is more scientific, accurate, and more in line with the current traffic conditions, effectively ensuring that the target vehicle can safely and quickly drive to the nearest service area for parking. On the other hand, once the tire condition meets the preset blowout conditions, the system instructs the user to perform at least one of the following actions based on the location of the tire damage: release the accelerator pedal, downshift, shorten the brake pedal stroke, and turn the steering wheel within a preset angle, until the vehicle reaches any nearby service area. It is evident that the entire simulated blowout process is highly intelligent and has a certain level of safety assurance.

[0090] See Figure 2 ,like Figure 2The diagram shows a structural schematic of a vehicle balance control device 20, which can be applied to a virtual driving control system. The virtual driving control system includes a simulator (virtual controller), a vehicle perception model, and a driving scenario simulation platform. The driving scenario simulation platform includes a first area and a second area. The first area displays multiple driving modes, each including at least two road segment materials. The second area currently displays dynamic footage under the tire blowout prevention driving mode. The dynamic footage includes a moving target vehicle and at least two road segment materials corresponding to the tire blowout prevention driving mode. The dynamic footage and trajectory data of the target vehicle in the second area are transmitted to the vehicle perception model via a port. The vehicle balance control device 20 in this embodiment can achieve the above-mentioned...

[0092] The processing module 202 can be used to determine that the current first vehicle tire pressure of the target vehicle meets the preset abnormal tire pressure conditions if it is determined that the first vehicle speed is greater than the first threshold and the first duration is greater than the first preset duration; wherein, the first duration is the duration during which the first vehicle speed is higher than the first threshold.

[0093] A first prompt message is generated and output through the input / output module 201. The first prompt message is used to instruct the target vehicle to drive to the nearest service area of ​​the target vehicle according to the target safe parking navigation guide.

[0094] If no confirmation operation from the user is received regarding the target safe parking navigation guidance within the second time period, the second speed of the target vehicle is obtained in real time through the input / output module.

[0095] If the second vehicle speed is greater than the second threshold and the second duration is greater than the second preset duration, then it is determined that the tires of the target vehicle meet the preset tire blowout conditions; wherein, the second duration is the duration during which the second vehicle speed is higher than the second threshold, the first duration is less than the second duration, the first preset duration is less than the second preset duration, and the first threshold is less than the second threshold.

[0096] The location of the damaged tire of the target vehicle is obtained, and a second prompt message is generated and output through the input / output module 201 based on the location of the damaged tire. The second prompt message is used to prompt the user to perform at least one of the following operations: release the accelerator pedal, downshift, shorten the braking distance, and turn the steering wheel within a preset angle, until the vehicle reaches any nearby service area.

[0097] In one embodiment, the processing module 202 is further configured to:

[0098] Acquire prior knowledge of safe handling procedures in the event of a tire blowout;

[0099] Based on the prior knowledge of safety procedures, select at least one treatment operation that matches the location of the tire damage;

[0100] The second prompt message is generated based on the selected at least one processing operation and output through the input / output module 201.

[0101] In one embodiment, the prior knowledge of safety procedures corresponding to different tires of the target vehicle when the tire damage location is the same, different, or overlapping.

[0102] In one embodiment, the processing module 202 is specifically used for:

[0103] Obtain the current target location of the target vehicle;

[0104] Determine the set of nearby service areas within a preset range of the target location;

[0105] Select at least one target nearby service area from the set of nearby service areas whose current service status is idle or not busy;

[0106] Based on the target location, the at least one nearby service area, and the traffic conditions along the route from the target location to each nearby service area, multiple candidate safe parking navigation directions are generated.

[0107] Select the target safe parking navigation guide from multiple candidate safe parking navigation guides according to priority;

[0108] The first prompt message is generated based on the target safe parking navigation guide and output through the input / output module 201.

[0109] This solution can intelligently simulate the entire process of a simulated tire blowout, and the simulation process has a certain degree of safety assurance, enabling users to quickly learn the correct handling measures after a tire blowout.
