Description

Technical Field

[0001] This invention relates to the field of cockpit control, and more particularly to a proactive defense control method for risk areas based on vehicle cockpit control. Background Technology

[0002] During normal driving, vehicles will pass through different areas. Some areas have certain risks in their external environment, such as severe weather, air quality, industrial pollutants, bacteria and viruses. Therefore, when approaching or entering these areas, the external environment may enter the vehicle in the form of gases through windows, affecting the health and safety of the driver and passengers.

[0003] Although navigation software allows setting the range based on different regional risk levels, it currently only displays the risk area through the navigation system and cannot provide truly effective protection. Summary of the Invention

[0004] In view of the above, the present invention aims to provide a risk area active defense control method based on vehicle cockpit control to solve the aforementioned technical problems.

[0005] The technical solution adopted in this invention is as follows:

[0006] This invention provides a risk area active defense control method based on vehicle cockpit control, including:

[0007] During vehicle operation, information on risk areas along the route is continuously acquired and the vehicle's current location is determined at preset intervals.

[0008] Based on the risk area information and the current location information, it is determined whether the vehicle is approaching or entering the risk area;

[0009] If so, a prompt message will be output and the vehicle's air conditioning and windows will be triggered to execute preset active defense strategies. The air conditioning defense strategy includes the following combinations of control: forced adjustment of internal and external circulation modes, air volume, air temperature, and air outlet direction; the window defense strategy includes forced closure of all vehicle windows.

[0010] In at least one of the possible implementations, determining whether a vehicle is approaching a risk area includes:

[0011] The distance between the current location information and the preset risk area boundary, as well as the vehicle's driving direction, are detected.

[0012] In at least one of the possible implementations, the risk area includes a number of pre-defined risk areas with different risk levels.

[0013] In at least one of the possible implementations, triggering the vehicle air conditioning and windows to execute a preset active defense strategy includes: triggering the vehicle air conditioning and windows to execute a corresponding defense strategy based on the different levels of risk areas that the vehicle approaches or enters.

[0014] In at least one possible implementation, the active defense strategy further includes: dynamically changing the degree of control of the active defense strategy based on the distance between the vehicle and the geographical center of the preset risk area.

[0015] In at least one possible implementation, the active defense control method further includes: if, based on the current location information and the vehicle's driving direction, it is determined that the vehicle has left the risk area, then the air conditioning and windows are triggered to return to their state before the defense.

[0016] In at least one possible implementation, the active defense control method further includes: after triggering the execution of the active defense strategy, if manual control of the air conditioner or windows is detected, then exiting the active defense strategy.

[0017] In at least one possible implementation, the proactive defense strategy further includes: triggering an output alert signal and providing a temporary navigation route to avoid or leave the risk area.

[0018] The main design concept of this invention lies in two aspects: firstly, it can continuously acquire risk area information during driving; secondly, based on vehicle positioning information, it can detect whether the vehicle is approaching or has entered a risk area. When the vehicle approaches or enters a risk area, it can output a warning message and trigger the cabin to enter an active defense mode. This invention can automatically put the vehicle into a defensive state based on its positioning and the location of the risk area during driving, proactively responding to risks from the external environment in a prepared manner. This significantly reduces the impact of the external environment on passengers, thereby protecting their health and safety. Attached Figure Description

[0019] To make the objectives, technical solutions, and advantages of this invention clearer, the invention will be further described below with reference to the accompanying drawings, wherein:

[0020] Figure 1 A flowchart of a risk area active defense control method based on vehicle cockpit control provided in an embodiment of the present invention. Detailed Implementation

[0021] Embodiments of the present invention are described in detail below. Examples of these embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and should not be construed as limiting the present invention.

[0022] This invention proposes an embodiment of a risk area active defense control method based on vehicle cockpit control, specifically, as follows: Figure 1 As shown, it includes:

[0023] Step S1: During vehicle operation, continuously acquire risk area information along the route periodically and locate the vehicle's current position.

[0024] Step S2: Determine whether the vehicle is approaching or has entered a risk area;

[0025] If so, then execute step S3, output a prompt message, and trigger the vehicle air conditioning and windows to execute preset active defense strategies. The air conditioning defense strategy includes the following combinations of control: forced control of internal and external circulation modes, air volume, air temperature, and air outlet direction; the window defense strategy includes forced closure of all vehicle windows.

[0026] Furthermore, determining whether a vehicle is approaching a risk area includes detecting the distance between the current location information and the preset boundary of the risk area, as well as the vehicle's driving direction. That is, if it is determined that the distance between the vehicle and the preset boundary of the risk area is less than or equal to a preset distance threshold, and the vehicle's driving direction is simultaneously towards the risk area, then it is determined that the vehicle is approaching the risk area.

[0027] Furthermore, the risk area includes several preset risk areas with different risk levels. Based on this concept, triggering the vehicle's air conditioning and windows to execute preset defense strategies includes: triggering the vehicle's air conditioning and windows to execute corresponding defense strategies according to the different levels of risk areas the vehicle approaches or enters. The following example is provided for implementation reference:

[0028] There are three levels of risk areas, with the first level risk area having a higher risk level than the second level risk area, and the second level risk area having a higher risk level than the third level risk area.

[0029] When the vehicle is detected approaching or entering a Level 1 risk area, the air conditioning system is forced to switch to recirculation mode, the fan speed is set to level 3, and the temperature damper automatically switches to maintain the cabin temperature at approximately 24 degrees Celsius. The airflow mode is switched to low defrost mode. Simultaneously, the left front window, left rear window, right front window, right rear window, and sunroof are closed. The entire vehicle interior is protected from air exchange with the outside air and direct air contact with the user's face is prevented.

[0030] When a vehicle is detected approaching or entering a Level 2 risk area, the air conditioning system is forced to switch to internal circulation, the fan speed is set to level 3, and the temperature damper automatically switches to maintain the cabin temperature at around 24 degrees Celsius. The air outlet mode is set to blow only on the feet. At the same time, the left front window, left rear window, right front window, right rear window, and sunroof are closed.

[0031] When a vehicle is detected approaching or entering a Level 3 risk area, the air conditioning system will switch to external circulation with a 30% opening, set the fan speed to level 4, and automatically switch the temperature damper to maintain the cabin temperature at around 24 degrees Celsius. The airflow mode includes blowing air onto the face. At the same time, the left front window, left rear window, right front window, right rear window, and sunroof will be closed.

[0032] Here, we can also make preferential considerations and dynamically adjust the degree of active defense strategy according to the distance of the vehicle from the geographical center of the preset risk area. For example, the air conditioning opening degree, air volume, and air temperature mentioned above can be adjusted to be more "strict" as the vehicle gets closer to the center of the area.

[0033] In addition, the defense control method also includes: if it is determined that the vehicle has left the risk area based on the current location information and the vehicle's driving direction, the air conditioner and windows are triggered to return to the state before the defense. For example, if the air conditioner is restored to AUTO mode, each window will automatically return to the open and closed state before the defense. It can be understood that the real-time state of the windows and air conditioner can be recorded before the aforementioned active defense strategy is triggered, so as to facilitate the state reset after the defense.

[0034] Finally, two points can be added. First, during vehicle operation, manual control should have higher priority than automatic control. Even if an active defense strategy is triggered, if manual control of the air conditioning or windows is detected, the active defense strategy should be discontinued. Second, in some driving scenarios using navigation systems, if it is determined that the vehicle is approaching or entering a risk area, the active defense strategy may also include: triggering an output warning signal and providing a temporary navigation route to avoid or leave the risk area, such as providing different navigation paths to allow the vehicle to bypass the risk area and reach its destination, or providing a new route to leave the risk area more quickly.

[0035] In actual operation, the above embodiments can be implemented and enriched by the following modules: risk area information provision module, T-BOX module, cockpit domain control module, and TSP module.

[0036] The risk area information provision module can obtain risk prevention and control information from external platforms in advance or in real time, or it can obtain risk area setting information from navigation systems in advance or in real time. The T-BOX module can obtain risk area information periodically. Specifically, the T-BOX module can include MCU and MPU; while the cockpit domain control module mainly includes the air conditioning system and window system; the TSP module transmits data with the T-BOX module on the vehicle side.

[0037] (1) When the MPU of the T-BOX module determines whether the vehicle is approaching or entering the corresponding risk area through logic, that is, the GPS detection value is at a preset distance from the boundary of the risk area and the vehicle is moving towards the risk area, or the GPS detection value is less than or equal to the radius of the risk area, if so, a defense request event is sent to the MCU.

[0038] (2) Subsequently, preferably, the MCU can first determine whether it is necessary to wake up the vehicle network. If the vehicle network is in a dormant state, then wake-up is triggered; if the vehicle network is not in a dormant state, then the current network state is maintained.

[0039] (3) Next, perform a vehicle precondition check and authentication check. Preconditions may include vehicle mode, armed status, ignition key, etc. When the preconditions are met, the authentication check begins. After the preconditions and authentication are verified, the air conditioning control command is sent to the air conditioning system, and the control signals of each window (including the sunroof) are sent to the window system.

[0040] (4) Next, the air conditioning system drives the corresponding air conditioning internal and external circulation dampers, temperature dampers, mode dampers, blower speeds, etc. to the preset state, and the window system controls the left front window, left rear window, right front window, right rear window and sunroof to the closed state.

[0041] (5) After each actuator in the air conditioning system and window system completes the corresponding instruction movement, the MCU begins to perform post-condition judgment. Specifically, the T-BOX module can read the actual status of the internal and external circulation damper, temperature damper, mode damper, blower gear, left front window, left rear window, right front window, right rear window and sunroof, etc., and feed back these actual statuses to the MPU through UART, and then push them to the TSP module through the 5G device.

[0042] (6) Finally, after the TSP module receives the current status of the air conditioner and windows sent by the T-BOX module and successfully decrypts the data, it can push relevant messages to the user terminal via 5G and display them on the user terminal (such as an APP). For example, it can push: "Dear car owner, you have entered a level one risk area. For your safety, the air conditioner and windows in the smart cockpit have been switched to defense mode for you. Please drive with peace of mind."

[0043] During the execution of any of the aforementioned steps (1) to (6), the vehicle's MP5 or other devices can be triggered to remind drivers and passengers that the vehicle has approached or entered a specific risk area (the warning content can be found in the example above), and that appropriate protective measures should be taken, such as wearing a mask.

[0044] In summary, the main design concept of this invention lies in two aspects: firstly, it can continuously acquire risk area information during driving; secondly, based on vehicle positioning information, it can detect whether the vehicle is approaching or has entered a risk area. Furthermore, when the vehicle approaches or enters a risk area, it can output a warning message and trigger the cabin to enter an active defense mode. This invention can automatically put the vehicle into a defensive state based on its positioning and the location of the risk area during driving, proactively responding to risks from the external environment in a prepared manner. This significantly reduces the impact of the external environment on passengers, thereby protecting their health and safety.

[0045] In this embodiment of the invention, "at least one" refers to one or more, and "more than one" refers to two or more. "And / or" describes the relationship between related objects, indicating that three relationships can exist. For example, A and / or B can represent the existence of A alone, A and B simultaneously, or B alone. A and B can be singular or plural. The character " / " generally indicates that the preceding and following related objects have an "or" relationship. "At least one of the following" and similar expressions refer to any combination of these items, including any combination of singular or plural items. For example, at least one of a, b, and c can represent: a, b, c, a and b, a and c, b and c, or a and b and c, where a, b, and c can be single or multiple.
