[0003] In view of this, this application provides a tricycle windproof control system that can limit the speed of the tricycle according to the wind force.

[0004] This application proposes a windproof control system for a tricycle, which is installed on a tricycle. The windproof control system includes:

[0009] The tricycle has a risk of tipping over, and the controller is configured to control the speed limiting module to act on the power control component to adjust the upper limit of the tricycle's speed.

[0012] 5.5m / s≤V≤7.9m / s, the controller determines the wind force level to be medium wind, the controller determines the risk of the tricycle overturning to be medium risk, and the controller is configured to control the speed limiting module to act on the power control component to adjust the upper limit of the tricycle's speed to a first speed V1, 18km / h≤V1≤22km / h;

[0013] When V≥8.0m / s, the controller determines the wind force level to be high-intensity wind, the controller determines the risk of the tricycle overturning to be high-risk, and the controller is configured to control the speed limiting module to act on the power control component to adjust the upper limit of the tricycle's speed to the second speed V2, where 8km / h≤V2≤12km / h.

[0014] Optionally, in the tricycle windproof control system, the wind force level is medium wind, and the tricycle speed is higher than V1 during operation, the controller is configured to control the speed limiting module to act on the power control component, so that the tricycle speed decreases by ≤V1 at a rate of 0.4m / s to 0.6m / s per second.

[0015] And / or, if the wind force level is high wind and the tricycle's speed during operation is higher than V2, the controller is configured to control the speed limiting module to act on the power control component, causing the tricycle's speed to decrease to ≤V2 at a rate of 0.4m / s to 0.6m / s per second.

[0016] Optionally, the tricycle windproof control system further includes a steering sensor for collecting the steering angle of the tricycle.

[0031] When the confirmation module receives a confirmation command from the user, the controller is configured to control the speed limiting module to act on the power control component to adjust the upper limit of the tricycle's speed to the second speed V2.

[0032] If the confirmation module does not receive a confirmation command from the user, the controller is configured to control the speed limiting module to act on the power control component to adjust the upper limit of the tricycle's speed to the fifth speed V5, where 4km / h≤V5≤6km / h.

[0033] Optionally, in the tricycle windproof control system, the wind force level switches between the primary wind, the intermediate wind, and the high wind, and the controller is configured to control the warning module to display warning information corresponding to the wind force level on the instrument panel.

[0045] To make the technical solution and beneficial effects of this application more apparent and understandable, a detailed description is provided below by listing specific embodiments. The accompanying drawings are not necessarily drawn to scale, and local features may be enlarged or reduced to more clearly show the details of the local features; unless otherwise defined, the technical and scientific terms used herein have the same meanings as those in the technical field to which this application pertains.

[0046] This application proposes a windproof control system 100 for a tricycle, applied to a tricycle 200, such as... Figure 1-2 As shown, the tricycle windproof control system 100 includes a controller 10, a wind speed sensor 20, and a speed limiting module 30. The wind speed sensor 20 is used to collect wind speed V m / s. The wind speed sensor 20 is communicatively connected to the controller 10 to transmit the collected wind speed data to the controller 10. The speed limiting module 30 is communicatively connected to the controller 10 and is linked to the power control components of the tricycle 200. The speed limiting module 30 is configured to control the speed of the tricycle 200.

[0047] The controller 10 can determine the wind force level based on the wind speed V, and determine whether the tricycle 200 is at risk of tipping over based on the wind force level. When the tricycle 200 is at risk of tipping over, the controller 10 is configured to control the speed limit module 30 to act on the power control components to adjust the upper speed limit of the tricycle 200.

[0048] In the existing technology, tricycles are at risk of tipping over when they encounter crosswinds while driving. Most existing tricycles rely on the user's subjective judgment of wind force and tipping risk. The speed limit and warning functions of some tricycles are unrelated to wind factors and cannot dynamically adjust the vehicle speed according to wind direction and speed.

[0049] The tricycle windproof control system 100 provided in this application includes a controller 10, a wind speed sensor 20, and a speed limiting module 30. The wind speed sensor 20 and the speed limiting module 30 are communicatively connected to the controller 10. The high-precision wind speed sensor 20 collects ambient wind speed in real time, and the controller 10 automatically determines the wind force level and the risk of vehicle rollover. When a risk exists, the controller 10 uses the speed limiting module 30 to control the speed of the vehicle's power components, adjusting the upper limit of the vehicle speed in a timely manner. This solution achieves automatic monitoring, risk prediction, and active speed limiting for vehicle driving safety in windy conditions, effectively improving the driving stability and anti-rollover capability of the tricycle 200. The system has a simple structure, rapid response, high reliability, and strong practicality.

[0050] In some embodiments, the wind speed V is measured in the range of 0~30m / s with an accuracy of ±0.2m / s, which enables high-precision, wide-range real-time acquisition of environmental wind speed, ensuring the accuracy and reliability of wind force level determination, and providing precise data support for subsequent rollover risk assessment and speed limit control.

[0051] In some embodiments, the power control components of the tricycle 200 include a throttle or a motor controller, meaning that the tricycle 200 can be driven by oil or electricity, making the windproof control system compatible with tricycles of various power types, improving the system's versatility and adaptability, and facilitating the large-scale promotion and application of the product.

[0052] In some embodiments, the controller 10 is an embedded microprocessor (such as the STM32 series) with built-in wind force level determination algorithm and speed limit control logic. It features fast processing speed, timely control response, and stable and reliable operation. It can quickly complete risk assessment and speed limit command output, further improving the real-time performance and safety of wind protection speed limit control.

[0053] In some embodiments, the tricycle windproof control system 100 automatically powers on with the vehicle's power supply after the tricycle 200 is started, or it can be manually started via a separate switch in the driver's seat. After the power module is activated, it outputs a stable voltage to each module. Each module completes a self-test synchronously. After the self-test passes, the instrument panel 220 displays a green "Windproof System Ready" icon, and the system enters a standby monitoring state. If any module malfunctions (such as no sensor signal or communication interruption), the instrument panel 220 displays a red fault code (such as "E1 - Wind Speed ​​Sensor Failure" or "E2 - Power Linkage Abnormality"), the buzzer emits three short alarm sounds, the system suspends intervention functions, retains only basic monitoring functions, and re-executes the self-test process after the fault is resolved.

[0054] In some embodiments, when 3.4m / s≤V≤5.4m / s, the controller 10 determines that the wind force level is primary wind and the risk of the tricycle 200 overturning is low. At this time, the controller 10 does not send a control signal to the speed limiting module 30.

[0055] When 5.5m / s≤V≤7.9m / s, the controller 10 determines that the wind force level is moderate and the risk of the tricycle 200 overturning is moderate. At this time, the controller 10 controls the speed limiting module 30 to act on the power control component and adjusts the upper limit of the tricycle 200's speed to the first speed V1, where 18km / h≤V1≤22km / h, preferably 20km / h.

[0056] When V≥8.0m / s, the controller 10 determines that the wind force level is high-strength wind and that the risk of the tricycle 200 overturning is high. At this time, the controller 10 controls the speed limiting module 30 to act on the power control component to adjust the upper limit of the tricycle 200's speed to the second speed V2, where 8km / h≤V2≤12km / h, preferably 10km / h.

[0057] By classifying the wind speed V collected by the wind speed sensor 20 and setting different upper speed limits accordingly, the wind protection control system achieves refined and tiered control. This ensures driving safety while maximizing the normal driving capability of the tricycle 200, avoiding any impact on the user experience. Through this tiered speed limit strategy, the tricycle wind protection control system 100 can adaptively adjust the speed limit based on the actual wind force collected by the wind speed sensor 20, balancing the driving safety and traffic efficiency of the tricycle 200, and adapting to the usage needs in different weather scenarios.

[0058] In some embodiments, when the wind force level is moderate and the vehicle speed of the tricycle 200 is higher than V1, the controller 10 controls the speed limiting module 30 to act on the power control component, so that the speed of the tricycle 200 is reduced to ≤V1 at a speed of 0.4m / s to 0.6m / s, preferably at a speed of 0.5m / s.

[0059] In some embodiments, when the wind force is high and the tricycle 200's speed exceeds V2, the controller 10 controls the speed limiting module 30 to act on the power control components, causing the tricycle 200's speed to decrease from 0.4m / s to 0.6m / s to ≤V2, preferably at a smooth deceleration of 0.5m / s. The controller 10's use of a smooth deceleration method with the speed limiting module 30 avoids the impact and secondary safety hazards caused by sudden deceleration, improves the smoothness and ride comfort of the tricycle 200, and prevents rear-end collisions or loss of control of the tricycle 200 due to sudden deceleration.

[0060] In some embodiments, the tricycle windproof control system 100 further includes a steering sensor 40 for acquiring the steering angle of the tricycle 200. The steering sensor 40 is communicatively connected to the controller 10 to transmit the acquired steering angle to the controller 10. When the steering angle is ≥10°, the controller 10 determines that the tricycle 200 is in a steering driving state.

[0061] When the wind force is moderate and the tricycle 200 is in a turning state and its speed is higher than V3, where V3 = V1 - 5 km / h, preferably 15 km / h, the controller 10 controls the speed limiting module 30 to act on the power control component, so that the speed of the tricycle 200 is reduced to ≤V3 at a speed of 0.4 m / s to 0.6 m / s.

[0062] When the wind force is high, and the tricycle 200 is in a turning state and its speed is higher than V4, where V4 = V2 - 2 km / h, preferably 8 km / h, the controller 10 controls the speed limiting module 30 to act on the power control component, so that the speed of the tricycle 200 is reduced to ≤V4 at a speed of 0.4 m / s to 0.6 m / s.

[0063] The tricycle windproof control system 100 combines wind force level with steering status and driving speed data collected by the steering sensor 40 to perform multi-dimensional linkage control, significantly improving the driving safety and stability of the tricycle in complex wind fields and steering conditions. The controller 10 sets corresponding steering speed limit thresholds V3 and V4 according to different wind force levels (medium wind, strong wind), and uses a gradual deceleration method (0.4m / s~0.6m / s) to control the vehicle speed within a safe range. This avoids dangers such as rollover and fishtailing due to crosswinds during high-speed steering, while also preventing sudden deceleration from affecting driving comfort. Compared to traditional speed limit schemes that only limit speed based on wind force or vehicle speed, this system organically integrates wind force, steering angle, and driving speed, achieving refined and adaptive windproof speed limiting under steering conditions. While ensuring normal steering passage for the tricycle, it significantly improves the handling safety and structural stability of the vehicle when steering in windy environments, making it particularly suitable for open-type tricycles that are susceptible to crosswinds.

[0064] In some embodiments, the steering sensor 40 is installed on the steering handle 210 of the tricycle 200, which can directly and accurately collect the actual rotation angle of the steering handle 210, reflect the driver's steering intention and the steering driving state of the tricycle 200 in real time, avoid distortion of steering angle collection due to factors such as transmission clearance and installation position deviation, and improve the accuracy and timeliness of steering state determination.

[0065] In some embodiments, the tricycle wind protection control system 100 further includes a wind direction sensor 50 for acquiring wind direction angle α, the measurement range of which is 0°≤α≤360°. The wind direction sensor 50 is communicatively connected to the controller 10 to transmit the acquired wind direction angle α to the controller 10.

[0066] Specifically, when α is 0°, 180°, or 360°, the wind direction is parallel to the travel direction of the tricycle 200, and the controller 10 determines that the tricycle 200 is in a low-risk state. When 0° < α < 180° or 180° < α < 360°, the wind direction intersects with the travel direction of the tricycle 200, forming a crosswind or diagonal wind, and the controller 10 determines that the tricycle 200 is in a medium-risk or high-risk state. By introducing the wind direction sensor 50 to determine the wind direction, the influence of crosswinds and axial winds on the driving stability of the tricycle 200 is distinguished, making the rollover risk determination of the controller 10 more accurate, avoiding the speed limiting module 30 from executing invalid speed limiting operations, and further optimizing the system's safety control strategy.

[0067] In some embodiments, the wind direction sensor 50 and the wind speed sensor 20 are integrated into an integrated ultrasonic sensor, which is installed at the highest point on the roof of the tricycle 200. This effectively avoids the obstruction and interference of the vehicle body, passengers, and cargo on the airflow, ensuring that the collected wind direction and wind speed data truly reflect the natural wind field information of the tricycle's driving environment. At the same time, the integrated structure simplifies the wiring and installation layout of the vehicle, reduces the space occupied by the sensor, and improves the system integration and reliability.

[0068] In some embodiments, the wind direction sensor 50 has an accuracy of ±5°, with true north as 0° and the angle increasing clockwise. The standardized angle definition method facilitates the controller 10 to make unified judgments and processes on the wind direction.

[0069] In some embodiments, when the wind force level switches between moderate and strong winds, the controller 10 controls the speed limiting module 30 to act on the power control components, so that the upper speed limit of the tricycle 200 matches the upper speed limit corresponding to the wind force level after the switch. When the wind force level switches to low wind (low risk), the controller 10 stops sending control signals to the speed limiting module 30, releases the speed limit on the tricycle 200, and restores the vehicle's original power response. The controller 10 realizes real-time linkage between dynamic wind force level switching and the speed limit of the speed limiting module 30, automatically releasing the speed limit when the wind weakens, without requiring manual operation throughout the process, thus improving the intelligence level of the tricycle wind protection control system 100 and the convenience of user operation.

[0070] In some embodiments, the tricycle wind protection control system 100 further includes a warning module 60, which is used to issue warning information and is communicatively connected to the controller 10 and the instrument panel 220 of the tricycle 200, respectively. During the operation of the tricycle 200 or before the user prepares to drive the tricycle 200, the controller 10 can control the warning module 60 according to the wind force level to display the corresponding warning information on the instrument panel 220.

[0071] When the wind force level is at the low level, the controller 10 controls the warning module 60 to display the first warning information on the instrument panel 220. The first warning information is a green light breeze icon accompanied by the text "Travel with caution, drive carefully," and it continues to be displayed until the wind force level changes.

[0072] When the wind force is moderate, the controller 10 controls the warning module 60 to display a second warning message on the instrument panel 220. The second warning message is a yellow wind icon combined with the text "Drive at low speed, be careful when turning," and the text flashes to enhance the warning effect.

[0073] When the wind force level is high, the controller 10 controls the warning module 60 to display the third warning information on the instrument panel 220. The third warning information is a red rollover risk sign accompanied by the text "High rollover risk, proceed only after confirmation," and the text flashes rapidly while a buzzer sounds for 1 second.

[0074] The controller 10 controls the warning module 60 to execute tiered warning prompts, enabling users to be aware of the current wind risk level in advance and take proactive precautions and drive cautiously. This combines the passive safety control of the speed limit module 30 with the active warning reminders of the warning module 60. Furthermore, the warning module 60 displays the warning information intuitively on the instrument panel 220 in the form of text and icons, ensuring timely and clear information delivery, facilitating quick risk identification by users, and improving their driving prediction capabilities.

[0075] In some embodiments, the warning module 60 is integrated with the vehicle instrument panel 220, eliminating the need for an additional independent display device and installation space. This simplifies the overall vehicle structure and wiring layout, reduces system complexity and cost, and allows the driver to intuitively and quickly obtain wind warning information while driving.

[0076] In some embodiments, corresponding warning information is displayed in the central prominent area of ​​the instrument panel 220. The display position of the warning information does not obstruct core driving data such as vehicle speed and fuel level. While ensuring that the warning prompts are clear and conspicuous, it does not affect the driver's normal observation and judgment of the vehicle's basic operating status.

[0077] In some embodiments, the tricycle windproof control system 100 further includes a confirmation module 70, which is used to receive confirmation commands issued by the user and is communicatively connected to the controller 10.

[0078] For example, when the wind force is high, the controller 10 controls the confirmation module 70 to issue a confirmation signal corresponding to the third warning information. If the confirmation module 70 receives a confirmation command from the user, the controller 10 controls the speed limiting module 30 to act on the power control component, adjusting the upper speed limit of the tricycle 200 to the second speed V2. If the confirmation module 70 does not receive a confirmation command from the user, the controller 10 controls the speed limiting module 30 to act on the power control component, adjusting the upper speed limit of the tricycle 200 to the fifth speed V5, where 4km / h≤V5≤6km / h, preferably 5km / h. By adding a user confirmation step to the confirmation module 70, safety constraints in high wind environments are strengthened. When no user confirmation command is received, the controller 10 controls the speed limiting module 30 to further reduce the upper speed limit, maximizing the driving safety of the tricycle 200 in extreme wind conditions. This also balances the intelligent control of the controller 10 with the human confirmation of the confirmation module 70, improving decision-making flexibility in emergency scenarios.

[0079] In some embodiments, users can send confirmation commands by pressing the confirmation button next to the instrument panel 220 or by issuing voice commands. The operation is simple and intuitive, and users can complete the safety confirmation without having to spend too much attention. This not only meets the control requirements for rapid response under high wind conditions, but also adapts to different usage habits and driving scenarios, improving the convenience and practicality of human-machine interaction.

[0080] In some embodiments, when the wind force level switches between low, medium, and high wind, the controller 10 controls the warning module 60 to display warning information corresponding to the switched wind force level on the instrument panel 220, and the switching process of the warning information is smooth. The warning information of the warning module 60 is updated synchronously with the wind force level in real time, ensuring that users can continuously obtain the latest risk warnings, making the continuity and real-time performance of the warnings stronger, and improving the overall safety protection effect of the tricycle wind protection control system 100.

[0081] It is understood that, in some embodiments, the tricycle windproof control system 100 also includes a power supply module for supplying power to each module. The power supply module is electrically connected to the controller 10, wind speed sensor 20, speed limit module 30, steering sensor 40, wind direction sensor 50, warning module 60, and confirmation module 70. The power supply module is powered by the tricycle's onboard 12V / 24V battery and has a built-in voltage regulator circuit and overload protection module, which can output a stable voltage to each module to ensure stable system operation.

[0082] In some embodiments, the tricycle windproof control system 100 meets the following conditions: the acquisition frequency of the wind speed sensor 20 and the wind direction sensor 50 is 4Hz~6Hz, preferably 5Hz. By setting a reasonable acquisition frequency, high-frequency and continuous acquisition of wind speed and wind direction data can be achieved, avoiding the omission of sudden gust data due to excessively long acquisition intervals, and ensuring that the controller 10 can obtain wind condition information that best matches the real-time environment in a timely manner. It is understood that the data acquisition process of the wind direction sensor 50 is not affected by weather factors such as light rain and dust. After the acquired raw data is digitally processed, it is transmitted to the controller 10 through a signal line with a transmission delay of ≤10ms.

[0083] In some embodiments, the tricycle windproof control system 100 satisfies the following condition: the controller 10 updates the wind force level determination result every 25ms to 35ms. By setting a shorter determination result update cycle, the controller 10 can quickly iterate the wind force level determination conclusion, track wind condition changes in a timely manner, avoid untimely windproof control due to delayed determination results, and ensure that the controller 10 can quickly trigger the corresponding speed limit control command when the wind force changes suddenly, thereby improving the system's ability to respond to sudden changes in wind conditions. In other embodiments, the determination response time of the tricycle windproof control system 100 is ≤30ms, and if a sudden increase in wind speed occurs, the overall system response time is ≤50ms.

[0084] Understandably, when the tricycle 200 is turned off, the tricycle windproof control system 100 automatically cuts off power, the power module stops supplying power, and the system can save wind-related data for this trip, including the highest wind speed and warning duration. Users can query the above data through the instrument panel 220 when the system is restarted next time. At the same time, the system completes initialization preparation and waits for restart and enters working state.

[0085] To more clearly illustrate the practical application effect of the tricycle windproof control system 100 of this application, the following describes in detail the working process and protective effect of the system in four typical driving scenarios. In each scenario, the various modules of the system work together and follow the above control logic:

[0086] Scenario 1: Cross-traffic in moderate winds on urban roads (medium-risk scenario)

[0087] In this scenario, a passenger tricycle carrying 200 people is traveling on a secondary urban road and encounters a continuous southwest wind (wind direction angle α=225°, which is a crosswind perpendicular to the vehicle body). The wind speed is V=6.5m / s, which is a moderate wind. The initial speed of the tricycle is 25km / h, and the driver is preparing to make a left turn.

[0088] The operation of the tricycle wind protection control system 100 is as follows: First, the wind speed sensor 20 and wind direction sensor 50 collect the wind direction angle α=225° and wind speed V=6.5m / s, and transmit the data to the controller 10 in real time. The controller 10 determines that the wind force level is moderate and then generates a second warning command and a speed limit command of "basic speed limit ≤20km / h". After receiving the command, the warning module 60 displays a yellow flashing icon and the second warning message "low speed driving, turn with caution" on the instrument panel 220. After visually perceiving this, the driver begins to actively decelerate. At the same time, the speed limit module 30 detects that the current vehicle speed of 25km / h exceeds the speed limit value. Under the control of the controller 10, it acts on the power control component to achieve smooth deceleration by reducing power output. After 3 seconds, the vehicle speed drops to 19km / h and stabilizes within the speed limit range. The driver then turns the steering handle 210, and the steering sensor 40 collects the steering angle of 15° and transmits it to the controller 10. The controller 10 triggers a steering enhancement speed limit command, and the speed limit module 30 further smoothly reduces the vehicle speed to 14km / h, helping the tricycle 200 to complete the left turn smoothly.

[0089] In this scenario, the tricycle windproof control system 100 effectively counteracts the combined risks of crosswinds and centrifugal forces through graded warnings and enhanced speed limits during steering. The tricycle 200 can then be smoothly steered without tilting or swaying, completely avoiding the risk of tipping over.

[0090] Scenario 2: Sudden gusts of strong winds in urban-rural fringe areas (high-risk scenario)

[0091] In this scenario, a freight tricycle carrying 100kg of goods is traveling on a road in a suburban area. Initially, the wind speed is V=2.0m / s in a windless state. Suddenly, a northeast gust of wind (wind direction angle α=45°, which is a diagonal wind) occurs, and the wind speed V instantly rises to 8.5m / s, which is a strong wind. The current speed of the tricycle is 30km / h, and the driver does not notice the sudden change in wind force.

[0092] The operation of the tricycle wind protection control system 100 is as follows: The wind speed sensor 20 and wind direction sensor 50 quickly detect the parameter changes of wind speed increasing from 2.0 m / s to 8.5 m / s and wind direction angle α=45°, and immediately transmit the data to the controller 10. Within 0.03s, the controller 10 determines that the wind force level is high-intensity wind and simultaneously generates a third warning command, a speed limit command of "basic speed limit ≤10km / h", and a user confirmation trigger command. After receiving the command, the warning module 60 displays a rapidly flashing red icon and the third warning information "high risk of rollover, confirm before proceeding" on the instrument panel 220, while the buzzer sounds a long 1-second beep, allowing the driver to immediately perceive the risk. The speed limit module 30 detects that the current vehicle speed of 30km / h far exceeds the speed limit value, and under the control of the controller 10, it decelerates rapidly and smoothly at a speed of 0.5m / s, while limiting the throttle output. After 5 seconds, the vehicle speed drops to 9km / h. The driver presses the confirmation button next to the instrument panel 220. The confirmation module 70 receives the confirmation command and transmits it to the controller 10. The system maintains the speed limit status and the warning continues to be displayed. After 10 seconds, the gusts subside and the wind speed drops to 7.0 m / s, which is a moderate wind. The controller 10 automatically updates the judgment result, the warning module 60 switches to the second warning information, and the speed limit module 30 adjusts the basic speed limit value to ≤20 km / h. The driver can drive normally within the new speed limit range.

[0093] In this scenario, the tricycle wind protection control system 100 has the ability to respond quickly to sudden high winds. Through emergency speed limits and clear graded warnings, it effectively avoids the problem of vehicle tilting caused by the combination of uneven cargo loading and high winds, ensuring driving safety. At the same time, the user confirmation mechanism takes into account the flexibility of driving decisions in emergency scenarios.

[0094] Scenario 3: Driving at an angle on a rural road in a light wind (low-risk scenario)

[0095] In this scenario, the cargo tricycle 200 is traveling unloaded on a rural road and encounters a southeast wind (wind direction angle α=135°, which is a diagonal wind) with a wind speed of V=4.0m / s, which is a primary wind. The tricycle 200 is traveling at a speed of 30km / h, and the road surface is flat with no steering operation required.

[0096] The operation of the tricycle windproof control system 100 is as follows: Wind speed sensor 20 and wind direction sensor 50 collect wind direction angle α=135° and wind speed V=4.0m / s, and transmit the data to controller 10. Controller 10 determines the wind level to be a primary wind and generates only a first warning command, without outputting a speed limit command. After receiving the command, warning module 60 displays a green light breeze icon and the first warning message "Travel with caution, drive carefully" on instrument panel 220. Speed ​​limit module 30 does not receive a control signal and does not interfere with the power output of tricycle 200. Wind speed sensor 20 and wind direction sensor 50 maintain a sampling frequency of 5Hz, and the wind speed is monitored in real time and stabilized at 4.0m / s. Controller 10 maintains the primary wind determination result, the system continues to display the first warning message, and tricycle 200 maintains a normal driving speed of 30km / h.

[0097] In this scenario, the primary wind has little impact on the driving stability of the tricycle 200. The tricycle windproof control system 100 only provides warning prompts without interfering with the driving speed, ensuring basic driving safety while taking into account driving efficiency, and is perfectly adapted to daily low-risk wind driving scenarios.

[0098] Scenario 4: Strong winds at an intersection causing a turn (extremely high-risk scenario)

[0099] In this scenario, a passenger tricycle carrying 3 people is waiting at a red light at an intersection. At this time, a continuous northwest wind blows (wind direction angle α=315°, which is a crosswind perpendicular to the vehicle body), and the wind speed V=9.0m / s is a strong wind. After the green light turns on, the driver prepares to make a right turn.

[0100] The operation of the tricycle wind protection control system 100 is as follows: During the red light waiting phase, the wind speed sensor 20 and wind direction sensor 50 collect a wind speed of V=9.0m / s. The controller 10 determines this to be a strong wind, and the warning module 60 immediately triggers the third warning information accompanied by a buzzer. The driver presses the confirmation button to complete the risk confirmation, and the confirmation module 70 transmits the command to the controller 10. The speed limiting module 30 adjusts the basic speed limit to ≤10km / h. After the green light turns on, the driver starts the tricycle 200, and the speed gradually increases to 9km / h. The speed limiting module 30 maintains the basic speed limit. Subsequently, the driver turns the steering handle 210 to make a right turn. The steering sensor 40 collects a steering angle of 25° and transmits it to the controller 10. The controller 10 immediately triggers a steering enhancement speed limiting command, and the speed limiting module 30 fine-tunes the power output, reducing the speed to 7.5km / h. After the driver completes the right turn and straightens the steering handle 210, the steering sensor 40 detects that the steering angle is ≤5°, the controller 10 releases the steering enhancement speed limit, the speed limit module 30 restores the vehicle speed to 9km / h, and the tricycle 200 drives normally.

[0101] In this scenario, the combination of strong winds and steering maneuvers poses an extremely high risk of the tricycle 200 overturning. The tricycle wind protection control system 100 employs a dual control strategy of "basic speed limit + steering-enhanced speed limit" to significantly reduce the combined effects of lateral force and steering centrifugal force, enabling the tricycle 200 to smoothly complete steering maneuvers without the risk of overturning. It is particularly suitable for high-frequency steering scenarios such as intersections and curves.
