Description

Technical Field

[0001] This invention belongs to the field of vehicle control technology, and more specifically, relates to a method and system for controlling an electric side tent in a vehicle. Background Technology

[0002] With the increasing popularity of leisure activities such as self-driving tours and outdoor camping, electric side tents, as a type of electrically deployable and retractable sunshade and rain protection device installed on the side of a vehicle, have gained increasing favor among users. Electric side tents provide users with a convenient semi-outdoor leisure space next to their vehicle, greatly enhancing the convenience and comfort of outdoor activities.

[0003] Currently, some electric side tent products and related control technologies have appeared on the market. The existing control methods for electric side tents mainly include the following: (a) Independent remote control Most existing motorized side tent products come with an independent wireless remote control, allowing users to unfold and retract the tent using buttons on the remote. For example, some products use a dedicated remote control device, where a single button on the remote controls the motor to drive the rotating shaft, enabling the side tent to unfold and retract automatically. However, remote controls are prone to loss, battery depletion, and damage, and users need to carry them separately and familiarize themselves with their operation, resulting in relatively poor ease of use.

[0004] (ii) Mobile APP control

[0005] Some existing solutions establish a communication connection between a mobile phone and the electric tent via Bluetooth, enabling control via a mobile app. For example, a patent discloses an intelligent circuit control system for an automatic tent, including a Bluetooth receiver module and a remote control receiver module, allowing intelligent control of the electric tent via both a remote control and mobile phone Bluetooth. Additionally, some solutions propose controlling a car sunshade system via mobile phone Bluetooth. However, mobile app control also suffers from cumbersome operation—users need to take out their phones, unlock them, open the app, and wait for a connection, and Bluetooth pairing is required before each use, resulting in a long operation chain and slow response time.

[0006] (iii) Voice control

[0007] Some existing solutions propose using voice recognition to control rooftop tents or side tents. However, voice control has a low recognition rate in noisy outdoor environments and requires users to issue explicit voice commands, making it impossible to achieve proactive control based on vehicle status awareness.

[0008] (iv) Vehicle-to-everything (V2X) Integrated Control

[0009] In recent years, with the improvement of vehicle intelligence, some models have begun to explore the integration and control of outdoor equipment with the vehicle's infotainment system. Existing solutions enable control of electric side tents via the central control screen, voice commands, and mobile phone operation, and support wireless connectivity between outdoor equipment and the vehicle's infotainment system. However, the aforementioned existing vehicle control solutions still have the following shortcomings: 1. Lack of vehicle status linkage: The existing vehicle control solution can only realize the unfolding and folding under the active operation of the user, and cannot automatically intervene in safety based on the vehicle's driving status (such as vehicle speed). When the vehicle is driving with the side tents not folded up, there is a huge wind resistance safety hazard, which may cause the tent to tear or even cause the vehicle to lose control.

[0010] 2. Lack of environmental awareness: The existing solution does not have the function of automatically adjusting the unfolding angle of the side tent based on the light intensity, and cannot provide users with the best sunshade effect in strong light environment.

[0011] 3. Lack of multi-device collaborative control: Although some solutions have achieved the connection between a single device and the vehicle, they lack the ability to collaboratively control multiple outdoor equipment based on Mesh networking, and cannot realize the scenario-based linkage control of equipment such as side tents, rooftop tents, and outdoor lighting.

[0012] 4. Limited Safety Mechanisms: Existing electric side tent products generally lack anti-pinch protection mechanisms during deployment or folding, posing a safety hazard of pinching people (especially children) or pets. While some high-end models have anti-pinch functions on rooftop tents, the anti-pinch protection of side tents, as independent outdoor equipment, has not received sufficient attention or a systematic solution.

[0013] 5. Lack of fault diagnosis and remote upgrade capabilities: Existing side-mounted tent products are all independent peripherals and do not have the ability to deeply interact with the vehicle system, so they cannot achieve fault self-diagnosis and remote firmware upgrades, and the product functions cannot be continuously iterated.

[0014] In summary, there is currently a lack of an electric side tent control scheme that can deeply integrate with vehicles, achieve automatic intervention for driving safety, adaptive environmental control, and collaborative management of multiple devices. Summary of the Invention

[0015] The purpose of this invention is to propose a method and system for controlling electric side tents in vehicles, solving the technical problem that existing electric side tents lack driving linkage with the vehicle and cannot automatically intervene in safety based on the vehicle's driving status, thus causing driving safety hazards. This invention achieves driving-linked safety control of the electric side tent, automatically restricting the side tent's deployment or driving it to retract while the vehicle is in motion, eliminating wind resistance safety hazards and improving driving safety.

[0016] To achieve the above objectives, in a first aspect, the present invention proposes a method for controlling an electric side tent by a vehicle, comprising: The vehicle's infotainment system establishes a wireless communication link with the electric side tent via a wireless communication module. The vehicle system acquires vehicle status signals, which include at least a vehicle speed signal. When the value of the vehicle speed signal is greater than or equal to a preset threshold, the vehicle system generates a control command and sends it to the electric side tent through the wireless communication module to restrict the deployment of the electric side tent or drive the electric side tent to retract.

[0017] Optionally, the wireless communication module is a Bluetooth communication module. The electric side tent forms a Bluetooth Mesh network with other outdoor equipment in the vehicle via the Bluetooth Mesh protocol. The vehicle-mounted unit acts as the master control node of the Bluetooth Mesh network, sending synchronous control commands and / or scene linkage commands to the other outdoor equipment through the Bluetooth Mesh network, and acquiring and displaying the device status information of each outdoor equipment in real time through the Bluetooth Mesh network.

[0018] Optionally, in response to a user-inputted unfold command, the vehicle system acquires a side obstacle detection signal and determines whether the available side space is greater than or equal to a preset space threshold. If so, the vehicle system generates an unfolding command and sends it to the electric side tent; If not, the vehicle system is prohibited from generating unfolding commands and issuing insufficient space warning messages.

[0019] Optionally, the vehicle status signal also includes a door status signal. When the electric side tent is in the deployed state, the vehicle system receives the door status signal indicating that all doors are closed, and the value of the vehicle speed signal is less than the preset threshold, the vehicle system generates a folding confirmation prompt on the vehicle screen. In response to the user's confirmation operation of the folding confirmation prompt, the vehicle system generates a folding command and sends it to the electric side tent, causing the electric side tent to perform the folding action.

[0020] Optionally, during the process of the electrically operated side tent performing the unfolding or retracting action, the following further includes: The operating parameters of the drive motor of the electric side tent are detected, including motor current and / or motor speed; The motion resistance of the electric side tent is determined based on the operating parameters. When the motion resistance is greater than or equal to a preset resistance threshold, the vehicle system generates a stop command and / or a reverse motion command and sends them to the electric side tent, causing the electric side tent to stop moving or reverse a preset distance.

[0021] Optionally, it also includes: The vehicle system acquires signals from the on-board light sensor, and the light sensor signals include light intensity information. When the light intensity information exceeds a preset light threshold, the vehicle system determines the target unfolding angle based on the light intensity information and generates an opening / closing percentage adjustment command, which is sent to the electric side tent to adjust the electric side tent to the target unfolding angle.

[0022] Optionally, the control command further includes an opening / closing percentage adjustment command, wherein the electric side tent performs an opening / closing percentage adjustment action according to the opening / closing percentage adjustment command, including: The vehicle system sends pulse width modulation signals or digital commands to the electric side tent through the wireless communication module to control the drive motor of the electric side tent to rotate to the target opening angle. The Hall sensor or angle sensor built into the electric side tent detects the actual opening and closing angle in real time and transmits the actual opening and closing angle data back to the vehicle's infotainment system. The vehicle system performs closed-loop correction based on the deviation between the actual opening angle data and the target opening angle until the actual opening angle reaches the target opening angle.

[0023] Optionally, it also includes: The vehicle's infotainment system obtains the firmware upgrade package for the electric side tent from the cloud server; The vehicle system transmits the firmware upgrade package in segments to the wireless communication module of the electric side tent via the wireless communication module; The wireless communication module of the electric side tent receives the complete firmware upgrade package and then performs firmware flashing.

[0024] Optionally, it also includes: The electric side tent transmits real-time operating status data back to the vehicle's infotainment system. The operating status data includes the drive motor current data, temperature data, and / or sensor data of the electric side tent. The vehicle's infotainment system determines whether a malfunction has occurred based on the operational status data. When it is determined that at least one of the following faults has occurred: motor overload, communication interruption, sensor malfunction, or excessive temperature, the vehicle system generates a corresponding fault prompt message and displays the fault prompt message and / or solution prompt on the vehicle system screen.

[0025] Secondly, this invention proposes a vehicle-to-electric side tent linkage control system, comprising: The electric side tent body integrates an electric drive module, a sensor module, and a first wireless communication module; The vehicle-mounted infotainment system has a built-in control program and includes a second wireless communication module and a vehicle status acquisition unit. The vehicle status acquisition unit acquires a vehicle status signal, which includes at least a vehicle speed signal. The vehicle system establishes a wireless communication link with the first wireless communication module of the electric side tent through the second wireless communication module; When the value of the vehicle speed signal is greater than or equal to a preset threshold, the vehicle system generates a control command and sends it to the electric side tent through the second wireless communication module to restrict the deployment of the electric side tent or drive the electric side tent to retract.

[0026] The beneficial effects of this invention are as follows: Through the wireless communication link between the vehicle-mounted system and the electric side tent, the vehicle-mounted system can acquire vehicle speed signals in real time and automatically generate control commands to send to the electric side tent when the vehicle speed reaches a preset threshold. This enables automatic restriction or forced closure of the side tent's deployment, thereby deeply linking the control of the side tent with the vehicle's driving status. This avoids wind resistance safety hazards caused by the side tent not being closed during vehicle operation, significantly improving driving safety. At the same time, the above control process does not require manual operation by the user. When the vehicle speed reaches a dangerous threshold, the vehicle-mounted system automatically and instantly intervenes, with fast response speed and high reliability. This effectively reduces the safety risks caused by user forgetfulness or misoperation, and improves the intelligent control level of vehicle outdoor equipment.

[0027] The system of the present invention has other features and advantages that will be apparent from or will be set forth in detail in the accompanying drawings and following detailed description, which together serve to explain the particular principles of the invention. Attached Figure Description

[0028] The above and other objects, features and advantages of the present invention will become more apparent from the accompanying drawings, in which like reference numerals generally denote like parts.

[0029] Figure 1 A flowchart illustrating the steps of a vehicle control method for an electric side tent according to Embodiment 1 of the present invention is shown. Detailed Implementation

[0030] The present invention will be described in more detail below with reference to the accompanying drawings. Although the preferred embodiments of the present invention are shown in the drawings, it should be understood that the present invention may be embodied in various forms and should not be limited to the embodiments set forth herein. Rather, these embodiments are provided to make the present invention more thorough and complete, and to fully convey the scope of the present invention to those skilled in the art.

[0031] Example 1

[0032] As shown in Figure 1 , the present embodiment provides a method for a vehicle to control an electric side awning, comprising: S1. The vehicle infotainment system establishes a wireless communication link with the electric side awning via the wireless communication module; In this step, the wireless communication module is a Bluetooth communication module, the electric side awning forms a Bluetooth Mesh network with other outdoor equipment of the vehicle through the Bluetooth Mesh protocol, the vehicle infotainment system serves as the master node of the Bluetooth Mesh network, sends synchronous control instructions and / or scene linkage instructions to other outdoor equipment through the Bluetooth Mesh network, and acquires and displays the device status information of each outdoor equipment in real time through the Bluetooth Mesh network.

[0033] Specifically, the wireless communication module is preferably a Bluetooth communication module, and the electric side awning forms a Bluetooth Mesh network with other outdoor equipment of the vehicle (such as roof tents, outdoor lighting lamps, portable speakers, etc.) through the Bluetooth Mesh protocol. The Bluetooth Mesh network is an IoT communication technology based on Bluetooth Low Energy, which adopts a managed flooding mechanism to realize wireless communication and information transmission between nodes. The relay nodes participating in forwarding can expand the Bluetooth signal coverage range and enhance network robustness, so that the Bluetooth Low Energy network evolves from the traditional star topology to a mesh topology. As the master node of the Bluetooth Mesh network, the vehicle infotainment system undertakes core functions such as network management, instruction generation and distribution, and device status monitoring. The vehicle infotainment system sends synchronous control instructions and / or scene linkage instructions to other outdoor equipment through the Bluetooth Mesh network. For example, in the camping mode, the vehicle infotainment system can simultaneously send an unfolding instruction to the electric side awning, a lifting instruction to the roof tent, and a lighting instruction to the outdoor lighting lamp, so as to realize synchronous actions and scenario-based linkage control of multiple devices. At the same time, the vehicle infotainment system acquires the device status information of each outdoor equipment (such as unfolding / folding status, power information, connection status, etc.) in real time through the Bluetooth Mesh network, and displays the above information on the screen of the vehicle infotainment system for the user to view and manage in a centralized manner. Through Bluetooth Mesh networking, multiple outdoor devices can realize multi-device interconnection and collaborative control without an additional gateway, which significantly improves the integration and intelligence level of the vehicle outdoor equipment.

[0034] In this embodiment, the wireless communication module can also be any one of a WiFi communication module, a UWB (Ultra-Wideband) communication module, a ZigBee communication module, or a proprietary wireless radio frequency communication module. The specific choice can be made flexibly based on factors such as the actual application scenario, communication distance, power consumption requirements, and cost.

[0035] S2. The vehicle system acquires vehicle status signals, which include at least the vehicle speed signal. Specifically, in this step, the vehicle's infotainment system acquires vehicle status signals in real time via the CAN bus or in-vehicle Ethernet. These signals include at least the vehicle speed signal, which is the core basis for determining whether the vehicle is in a state requiring safety intervention. The system continuously monitors the speed signal and compares it with a preset threshold to determine if the vehicle is in a driving state requiring safety intervention. When the speed signal value is greater than or equal to the preset threshold, the system determines that the vehicle is in motion. If the side tent is deployed, it will face wind resistance safety hazards, triggering subsequent intervention control logic. The preset threshold can be set to a fixed value (e.g., 5 km / h) based on the vehicle model, the structural strength of the side tent, and actual application requirements.

[0036] S3. When the value of the vehicle speed signal is greater than or equal to a preset threshold, the vehicle system generates a control command and sends it to the electric side tent via the wireless communication module to restrict the deployment of the electric side tent or drive the electric side tent to retract.

[0037] Specifically, when the vehicle's infotainment system determines that the vehicle speed signal is greater than or equal to a preset threshold, it indicates that the vehicle is in motion. In this state, if the electric side tent is deployed, the wind resistance generated by the vehicle's movement will directly affect the tent's fabric and support structure, potentially causing tearing, frame deformation, or even detachment. In severe cases, this can affect vehicle stability and pose a significant driving safety hazard. Similarly, if the electric side tent is retracted, accidental activation of the deployment button during driving can also lead to the aforementioned safety risks. Therefore, the vehicle's infotainment system automatically generates corresponding control commands based on the vehicle speed signal determination and sends these commands to the electric side tent via a wireless communication module. The control command, depending on the current state of the electric side tent, includes two scenarios: When the electric side tent is currently deployed, the control command is a retraction command, used to force the electric side tent to retract, thereby eliminating wind resistance safety hazards in time when the vehicle speed reaches a dangerous threshold; when the electric side tent is currently retracted, the control command is a locking command, used to restrict the deployment operation of the electric side tent, for example, by disabling the deployment control button of the electric side tent on the vehicle's infotainment screen and blocking deployment signals from physical buttons and remote control, thereby preventing accidental deployment of the side tent due to user touch during driving. During the above control process, the drive motor of the electric side tent executes corresponding actions according to the received control command. If the control command is a retraction command, the drive motor is powered on and operates, driving the telescopic arm or roll of the side tent to retract through a transmission mechanism (such as a worm gear or rack and pinion mechanism) until the side tent is fully retracted; if the control command is a locking command, the vehicle's infotainment system locks the deployment function at the software level, does not send drive signals to the motor, and the motor remains stationary. The preset threshold can be set to a fixed value (e.g., 5 km / h) based on the vehicle model, the structural strength of the side tent, and its wind resistance tolerance. Alternatively, it can be dynamically determined based on the vehicle's current speed, the current deployment status of the side tent, and the ambient wind speed. For example, the preset threshold decreases accordingly when the wind speed is higher or the deployment angle is larger. When the vehicle speed drops below the preset threshold, the vehicle's infotainment system automatically unlocks the electric side tent deployment operation, restoring the user's normal control over the side tent, allowing for normal use while the vehicle is parked. Through this speed-linked control, a deep coupling between the vehicle's driving state and the electric side tent control is achieved. When the vehicle speed reaches a dangerous threshold, automatic and immediate intervention is possible without manual user operation. This fast response and high reliability effectively eliminate wind resistance safety hazards caused by the side tent not being retracted, significantly improving driving safety.

[0038] In this embodiment, in response to the user's input of an unfold command, the vehicle system acquires the obstacle detection signal on the side of the vehicle and determines whether the available space on the side is greater than or equal to a preset space threshold. If so, the vehicle's infotainment system generates an unfolding command and sends it to the electric side tent; If not, the vehicle's infotainment system will not generate an unfolding command and will issue a space shortage warning.

[0039] Specifically, in response to a user-inputted unfolding command, the vehicle's infotainment system first acquires obstacle detection signals from the sides of the vehicle. The user-inputted unfolding command can come from various sources, including but not limited to: touch commands input via the unfolding button on the vehicle's touchscreen control interface for the electric side tent; button commands input via preset physical buttons on the roof or inside the vehicle; voice commands input via the voice recognition system; or wireless control commands input via a remote control or mobile app. Upon receiving an unfolding command from any of the above sources, the vehicle's infotainment system does not immediately execute the unfolding action, but instead first initiates a pre-unfolding safety check process.

[0040] The vehicle's infotainment system acquires side obstacle detection signals through obstacle detection sensors installed on the sides of the vehicle. These sensors can be one or a combination of ultrasonic radar, millimeter-wave radar, or surround-view cameras installed on both sides of the vehicle. For example, with ultrasonic radar, multiple ultrasonic radar probes are typically installed on both sides of the vehicle, covering the front, side, and rear sides respectively. These sensors can detect the presence of walls, adjacent vehicles, trees, pillars, or other obstacles on the sides of the vehicle and measure the distance between the obstacle and the vehicle. Similarly, with surround-view cameras, cameras installed below the vehicle's exterior rearview mirrors capture real-time images of the sides of the vehicle. The infotainment system uses image recognition algorithms to identify obstacles in the images and calculate their distance to the vehicle. Based on these obstacle detection signals, the infotainment system determines whether the available space on the side is greater than or equal to a preset space threshold.

[0041] The preset space threshold is a minimum safe distance pre-set based on the lateral space required for the electric side tent to fully unfold. Its specific value is related to the mechanical structure dimensions of the electric side tent, such as the length of the telescopic arm and the width of the unfolded tent fabric. When the available lateral space is greater than or equal to the preset space threshold, it indicates that there is sufficient space on the side of the vehicle for the side tent to unfold safely. The vehicle's control system determines that the current environment meets the unfolding conditions, and then generates an unfolding command and sends it to the electric side tent via the wireless communication module. The drive motor of the electric side tent is powered on and runs, driving the telescopic arm or roller through the transmission mechanism to perform the unfolding action until the side tent is fully unfolded.

[0042] When the available space to the side is less than a preset threshold, it indicates insufficient space on the side of the vehicle. If the side tent is deployed under these conditions, the telescopic arm or tarpaulin will collide with walls, adjacent vehicles, or other obstacles, causing equipment damage or even personal injury. In this situation, the vehicle's infotainment system will not generate deployment commands, meaning it will not send any drive signals to the electric side tent, and the tent will remain retracted. Simultaneously, the system will display a space shortage warning on the screen, such as a pop-up message saying "Insufficient space to the side, unable to deploy the side tent, please check the surrounding environment," or similar text. This can be accompanied by voice prompts to clearly inform the user of the reason for the inability to deploy and to allow them to take appropriate measures (such as moving the vehicle to a location with more space). After issuing the space shortage warning, the system continuously monitors side obstacle detection signals. When a change in available space to the side is detected (such as an adjacent vehicle moving away) and the deployment conditions are met, the system can allow the user to initiate the deployment operation again, or automatically restore the deployment control button to its operable state, so that the user can use the side tent normally once environmental conditions improve. The aforementioned safety inspection mechanism before deployment effectively prevents the side tent from colliding with obstacles due to misoperation when there is insufficient side space, thus avoiding equipment damage and safety accidents and improving the safety of using electric side tents.

[0043] In this embodiment, the vehicle status signal also includes the door status signal. When the electric side tent is in the deployed state, the vehicle system obtains the door status signal indicating that all doors are closed, and the value of the vehicle speed signal is less than a preset threshold, the vehicle system generates a folding confirmation prompt on the vehicle screen. In response to the user's confirmation operation of the folding confirmation prompt, the vehicle system generates a folding command and sends it to the electric side tent, causing the electric side tent to perform the folding action.

[0044] Specifically, vehicle status signals also include door status signals. When the electric side tent is in the deployed state, the vehicle's infotainment system receives a door status signal indicating that all doors are closed, and the vehicle speed signal value is less than a preset threshold, the system determines that the user may have left the vehicle or is preparing to leave. At this time, the side tent is still in the deployed state. If the user forgets to fold it up and drives away directly, there will be a safety hazard due to wind resistance. Based on this judgment, the system does not immediately perform the folding action. Instead, it first generates a folding confirmation prompt on the screen, such as displaying a pop-up window asking "The side tent is in the deployed state, do you want to fold it up?" and providing two interactive operation options, "Confirm Folding Up" and "Cancel," for the user to choose from.

[0045] In response to the user's confirmation of the folding prompt (e.g., clicking the "Confirm Folding" button on the vehicle's infotainment screen), the vehicle's infotainment system generates a folding command and sends it to the electric side tent via a wireless communication module. The electric side tent's drive motor is then powered on, driving the telescopic arm or reel through a transmission mechanism to perform the folding action until the side tent is fully folded. If the user clicks the "Cancel" button or does not respond to the folding confirmation prompt within a certain time, the vehicle's infotainment system cancels the folding operation, and the electric side tent remains in the unfolded state. Simultaneously, the system continuously monitors the door status signal and vehicle speed signal. When the trigger conditions are met again, a new folding confirmation prompt can be generated to remind the user to fold the side tent, preventing potential driving safety hazards due to user forgetfulness. By generating a confirmation prompt for folding when all doors are detected to be closed and the vehicle speed is below a preset threshold, and only performing the folding operation after user confirmation, the system can proactively remind users to fold the side tent when they may leave the vehicle or are about to drive away, effectively reducing the driving safety risks caused by forgetting to fold it. At the same time, the final decision to fold the tent is left to the user, and the folding operation is only performed after the user actively confirms. This avoids the inconvenience caused by the system automatically folding the tent when the user does not need to fold it, such as when the user only gets out of the vehicle temporarily to retrieve something but still needs to keep the side tent in the unfolded state.

[0046] In this embodiment, during the unfolding or retracting of the electrically operated side tent, the following further steps are included: Detect the operating parameters of the drive motor of the electric side tent, including motor current and / or motor speed; Determine the motion resistance of the electric side tent based on the operating parameters; When the motion resistance is greater than or equal to the preset resistance threshold, the vehicle system generates a stop command and / or a reverse motion command and sends them to the electric side tent, causing the electric side tent to stop moving or move in the opposite direction a preset distance.

[0047] Specifically, during the unfolding or retracting of the electric side tent, the system simultaneously executes an anti-pinch control procedure.

[0048] The system monitors the operating parameters of the drive motor of the electric side tent in real time, including motor current and / or motor speed. Motor current detection can be achieved through a current detection module installed in the motor drive circuit, such as using a Hall effect current sensor or a sampling resistor in conjunction with an operational amplifier for current sampling. The detection accuracy of the current detection module is no less than ±1%, capable of capturing minute changes in the motor's operating current in real time. Motor speed detection can be achieved through a Hall sensor installed on the motor's output shaft or transmission mechanism. The Hall sensor outputs pulse signals based on changes in the magnetic field generated by the motor's rotation. The vehicle-mounted system or motor controller calculates the motor speed based on the number of pulses received per unit time. Alternatively, a high-precision speed detection can be achieved through an encoder installed on the motor. During the normal unfolding or retraction of the electric side tent, the drive motor's operating current and speed remain within a relatively stable range. When the telescopic arm or tent fabric encounters an obstacle (such as a person, pet, or other foreign object) during movement, the resistance to movement suddenly increases, increasing the load on the drive motor and causing a momentary increase in motor current and a momentary decrease in motor speed. Based on the direct proportional relationship between motor current and electromagnetic torque and the inverse proportional relationship between speed and load, the system can monitor the increase in motor current and / or the decrease in motor speed, and combine this with a preset motor parameter model or mapping relationship to convert the detected operating parameters into corresponding motion resistance values.

[0049] When the resistance determined by operating parameters is greater than or equal to a preset resistance threshold, the vehicle's infotainment system determines that the side tent has encountered an obstacle during movement and triggers the anti-pinch protection strategy. The preset resistance threshold is pre-set based on the maximum permissible resistance during normal movement of the electric side tent. For example, the preset resistance threshold can be set slightly higher than the maximum resistance value when the electric side tent moves normally without obstacles, to distinguish between normal movement resistance and abnormal clamping resistance, avoiding false triggering of the anti-pinch function due to fluctuations in normal resistance. This threshold can be calibrated at the factory based on the side tent's mechanical structure, motor characteristics, and actual usage scenarios. After triggering the anti-pinch protection strategy, the vehicle's infotainment system generates a stop command and / or a reverse movement command and sends it to the electric side tent via a wireless communication module. If the vehicle's infotainment system generates a stop command, the electric side tent's drive motor immediately stops operating, and the side tent's movement stops instantly, preventing further clamping of the obstacle. If the vehicle's infotainment system generates a reverse motion command, the drive motor will reverse and power on, causing the telescopic arm or roll to move in the opposite direction a preset distance, such as 50mm, so that the telescopic arm or tarpaulin of the side tent will disengage from the clamped obstacle, thereby releasing the clamped state and effectively preventing injury to people or pets.

[0050] The control commands for the aforementioned anti-pinch protection strategy are determined and sent by the vehicle's infotainment system within milliseconds, ensuring a timely response before the clamping force increases to the point of causing injury. Simultaneously with triggering the anti-pinch protection, the system displays a prompt message on its screen, such as "Obstacle detected, automatic stop" or similar content, informing the user of the reason for the anti-pinch trigger. After reversing the movement a preset distance and stopping, the electric side tent enters standby mode. Normal operation can resume by re-entering the unfolding or retracting command after the user removes the obstacle. Through this anti-pinch control mechanism based on real-time detection of motor operating parameters, clamping events can be effectively detected and responded to during the unfolding or retracting of the electric side tent, preventing injury to people or pets and significantly improving the safety of using the electric side tent.

[0051] In this embodiment, it also includes: The vehicle's infotainment system acquires signals from the vehicle's light sensor, which includes light intensity information. When the light intensity information exceeds the preset light threshold, the vehicle system determines the target unfolding angle based on the light intensity information and generates an opening / closing percentage adjustment command, which is sent to the electric side tent to adjust the electric side tent to the target unfolding angle.

[0052] Specifically, the system also includes an adaptive lighting control function. The vehicle's infotainment system acquires lighting sensor signals through an onboard lighting sensor, which includes at least light intensity information. The onboard lighting sensor can be an existing ambient light sensor, such as a sunlight sensor mounted below the windshield, typically used for lighting compensation control of automatic headlights and automatic air conditioning; or it can be a dedicated, independent lighting sensor for adaptive lighting control, preferably installed on the vehicle roof or exterior rearview mirror housing to avoid obstruction by the vehicle body and to more accurately sense ambient light intensity. The lighting sensor can use photosensitive elements such as photodiodes or phototransistors to convert ambient light intensity into an electrical signal output to the vehicle's infotainment system. The unit for light intensity information is usually lux (Lux), with a higher value indicating stronger ambient light.

[0053] After acquiring light intensity information, the vehicle's infotainment system compares this value with a preset light intensity threshold. This threshold is a pre-defined critical value used to determine whether the current environment is considered a strong light environment. For example, a preset threshold of 30,000 Lux indicates a strong light environment when the ambient light intensity exceeds 30,000 Lux. When the infotainment system determines that the light intensity exceeds the preset threshold, it determines the target deployment angle of the electric side tent based on this information. The system has a built-in mapping relationship between light intensity and deployment angle; the higher the light intensity, the larger the target deployment angle, meaning a greater deployment range of the side tent and a larger shading area, thus achieving adaptive shading control that is positively correlated with light intensity. The mapping relationship can be represented by a preset mapping table. For example, when the light intensity is in the range of 30,000 to 50,000 Lux, the target unfolding angle is 60% to 70% of the maximum unfolding angle of the side tent; when the light intensity is in the range of 50,000 to 70,000 Lux, the target unfolding angle is 70% to 85% of the maximum unfolding angle; and when the light intensity exceeds 70,000 Lux, the target unfolding angle is 85% to 100% of the maximum unfolding angle. Specific values ​​can be calibrated at the factory based on the shading area of ​​the side tent, the vehicle's usage scenario, and user comfort requirements. Alternatively, the mapping relationship can be represented as a linear function, where the target unfolding angle is linearly positively correlated with the light intensity. The vehicle's infotainment system continuously calculates the corresponding target unfolding angle based on the real-time light intensity using a linear interpolation algorithm. After determining the target unfolding angle based on the light intensity, the vehicle's infotainment system generates an opening / closing percentage adjustment command and sends it to the electric side tent via a wireless communication module, causing the electric side tent to adjust to the target unfolding angle. Upon receiving the opening / closing percentage adjustment command, the electric side tent activates its motor, which in turn drives the telescopic arm or roll-up mechanism to extend the tent to the target opening / closing percentage. During adjustment, the electric side tent's built-in Hall effect sensor or angle sensor continuously monitors the actual opening angle. The vehicle's infotainment system performs closed-loop correction based on the deviation between the actual and target opening angles until the actual opening angle reaches the target angle. The specific closed-loop control process is detailed later. Through this adaptive light control, the system can automatically increase the side tent's opening angle in strong sunlight to expand the shading area, providing users with a superior sunshade experience for outdoor camping and leisure activities without requiring manual adjustment, thus enhancing the vehicle's intelligence.

[0054] In this embodiment, the control command further includes an opening / closing percentage adjustment command. The electric side tent performs an opening / closing percentage adjustment action according to the opening / closing percentage adjustment command, including: The vehicle's infotainment system sends pulse width modulation signals or digital commands to the electric side tent via a wireless communication module, controlling the drive motor of the electric side tent to rotate to the target opening angle. The electric side tent has a built-in Hall sensor or angle sensor that detects the actual opening and closing angle in real time and transmits the actual opening and closing angle data back to the vehicle's infotainment system. The vehicle's infotainment system performs closed-loop correction based on the deviation between the actual opening angle data and the target opening angle until the actual opening angle reaches the target opening angle.

[0055] Specifically, the control commands generated by the vehicle's infotainment system also include opening / closing percentage adjustment commands. The electric side tent performs the opening / closing percentage adjustment action according to these commands. Users can set the target opening / closing angle using the opening / closing percentage adjustment controls (such as sliders or plus / minus buttons) on the electric side tent control interface of the vehicle's touchscreen. This target opening / closing angle is expressed as a percentage; for example, 50% means the side tent is extended to half of its maximum travel, and 100% means it is fully extended. After the user sets the target opening / closing angle, the vehicle's infotainment system generates the corresponding opening / closing percentage adjustment command and sends it to the electric side tent via the wireless communication module.

[0056] The vehicle's infotainment system sends pulse-width modulation (PWM) signals or digital commands to the electric side tent via a wireless communication module, controlling the tent's drive motor to rotate to the target opening angle. The PWM signal controls the motor's speed or rotation angle by adjusting the pulse width, i.e., the duty cycle. Different duty cycles correspond to different control values; for example, a larger duty cycle results in a higher motor speed and a larger rotation angle. The digital command is a control command sent in the form of data packets, containing target position information. For example, a digital command might include "forward" or "reverse" direction information and "rotate to a certain angle" position information, or it might include "forward" or "reverse" direction information and "rotate a preset number of steps" step information. In one implementation, the drive motor is a stepper motor. The pulse signals sent by the vehicle's infotainment system control the number of rotation steps of the stepper motor. Each pulse signal received by the stepper motor rotates a fixed angle. By controlling the total number of pulses, the total rotation amount of the motor can be precisely controlled; simultaneously, the frequency of the pulse signals controls the motor's rotation speed. The drive motor of the electric side tent is powered on according to the pulse width modulation signal or digital command. The rotational motion of the motor is converted into the linear motion of the telescopic arm or the rotational motion of the roll through the transmission mechanism (such as worm gear mechanism or rack and pinion mechanism), so that the opening and closing angle of the electric side tent gradually approaches the target opening and closing angle set by the user.

[0057] During the operation of the electric side tent's opening / closing percentage adjustment, the Hall effect sensor or angle sensor built into the tent detects the actual opening / closing angle in real time and transmits this data back to the vehicle's infotainment system via a wireless communication module. The Hall effect sensor can be installed on the output shaft of the drive motor or a rotating component of the transmission mechanism. It senses the number of rotations or the angle of the motor by detecting changes in the magnetic field, thus indirectly obtaining the actual opening / closing angle of the side tent. The angle sensor can be a potentiometer-type or magnetoresistive angle sensor, directly installed at the rotating joint of the side tent or the pivot position of the telescopic arm. It measures the angle between the telescopic arm and the vehicle body, thus directly obtaining the actual opening / closing angle. Taking a potentiometer-type angle sensor as an example, its output voltage is proportional to the rotation angle; the vehicle's infotainment system can calculate the current actual opening / closing angle by collecting the output voltage.

[0058] After receiving the actual opening angle data, the vehicle's infotainment system compares it with the target opening angle set by the user and calculates the deviation between the two. If the actual opening angle is less than the target opening angle, it indicates that the side tent has not yet fully deployed. The infotainment system maintains or adjusts the pulse width modulation signal or digital command sent to the electric side tent to keep the drive motor running in the forward direction to increase the deployment angle. If the actual opening angle is greater than the target opening angle, it indicates that the side tent has over-deployed. The infotainment system controls the drive motor to run in the reverse direction to decrease the deployment angle. If the actual opening angle is equal to the target opening angle, the deviation is zero, indicating that the side tent has reached the target position. The infotainment system stops sending drive signals to the drive motor, the motor stops, and the side tent remains at the current opening angle. The above comparison and correction process is repeatedly executed in a closed loop. The infotainment system continuously acquires the actual opening angle data at a preset sampling frequency (e.g., once every 50 milliseconds) and compares it with the target value. It adjusts the control signal output to the motor in real time according to the deviation until the actual opening angle stabilizes at the target opening angle, and the deviation remains within the allowable error range (e.g., ±1%), ultimately achieving high-precision opening percentage adjustment. Through the closed-loop correction control based on real-time feedback from Hall sensors or angle sensors, the electric side tent can be precisely adjusted to the target opening and closing angle set by the user, achieving precise control of any opening and closing percentage within the range of 0 to 100%, thus meeting the diverse needs of users for different shading areas and ventilation volumes of the side tent.

[0059] In this embodiment, it also includes: The vehicle's infotainment system retrieves the firmware upgrade package for the electric side tent from the cloud server; The vehicle's infotainment system transmits the firmware upgrade package in segments to the wireless communication module of the electric side tent via the wireless communication module; The wireless communication module of the electric side tent receives the complete firmware upgrade package and then performs firmware flashing.

[0060] Specifically, the system also includes OTA (Over-The-Air) remote upgrade functionality. The vehicle's infotainment system obtains the firmware upgrade package for the electric side tent from a cloud server via its communication unit. The cloud server, deployed and maintained by the vehicle manufacturer or outdoor equipment supplier, stores the latest firmware versions for various electric side tent models. The vehicle's infotainment system connects to the internet via a cellular network (e.g., 4G or 5G) to access the cloud server and query whether a firmware upgrade package suitable for the electric side tent is currently available. If a new firmware upgrade package exists on the cloud server, the vehicle's infotainment system downloads it from the cloud server and stores it in its local storage unit. The firmware upgrade package is a differential upgrade package, meaning it only contains the differences between the old and new firmware versions, rather than a complete firmware image file, thus significantly reducing the data size of the upgrade package and shortening download and transmission times.

[0061] After the vehicle's infotainment system downloads the firmware upgrade package, it transmits the package in segments to the wireless communication module of the electric side tent via the wireless communication module. Due to the limited data packet size in a single transmission and considering interference resistance and data integrity during transmission, the vehicle's infotainment system divides the complete firmware upgrade package into multiple data segments. Each data segment is appended with a serial number and verification information to facilitate data reassembly and integrity verification at the receiving end. The vehicle's infotainment system sends each data segment to the electric side tent sequentially at preset time intervals. Upon receiving a data segment, the electric side tent's wireless communication module sends an acknowledgment signal back to the vehicle's infotainment system, indicating successful reception. If the vehicle's infotainment system does not receive an acknowledgment signal for a data segment within a preset time, it automatically retransmits that segment, ensuring that all data segments are transmitted to the electric side tent completely and without loss. If transmission is interrupted due to vehicle engine shutdown, excessive communication distance, or other reasons, the vehicle's infotainment system supports a resume function, allowing transmission to continue from the point of interruption after the interruption is resolved, eliminating the need to re-transmit from the beginning and improving upgrade efficiency.

[0062] After receiving the complete firmware upgrade package, the wireless communication module of the electric side tent performs firmware flashing. Specifically, the wireless communication module of the electric side tent has a built-in microcontroller (MCU) and a storage unit. After confirming that all data segments have been received completely and verified, the microcontroller reassembles the data segments into a complete firmware upgrade package in sequence. Before the actual flashing, the microcontroller performs cyclic redundancy check (CRC check) or hash value check on the complete firmware upgrade package to verify the integrity and correctness of the upgrade package data. If the check passes, the microcontroller writes the upgrade package to the firmware storage area of ​​the storage unit, overwriting the original firmware program, and completes the firmware flashing process. If the check fails, the upgrade package is discarded, the firmware flashing is not performed, and an upgrade failure message is reported to the vehicle's infotainment system. Based on this, the vehicle's infotainment system prompts the user on the screen that the upgrade has failed and suggests trying again. Preferably, during the firmware flashing process, the microcontroller retains the original firmware program as a backup. Only after the new firmware program has been written and verified during startup (e.g., checking firmware header information and checksum) is it confirmed to be correct is the new firmware marked as active. If an anomaly occurs during the writing process (e.g., power failure, memory write error), the system automatically rolls back to the previous firmware version, ensuring that the electric side tent can start and run normally under any circumstances, avoiding device failure due to upgrade failure. Through the aforementioned OTA remote upgrade function, users do not need to drive their vehicles back to a service center or have professionals perform on-site operations. They can complete the firmware upgrade of the electric side tent through the connection between the vehicle's infotainment system and the cloud server, enabling the electric side tent to continuously receive functional optimizations, performance improvements, and security patches, thus enhancing product maintainability and user experience.

[0063] In this embodiment, it also includes: The electric side tent transmits real-time operating status data back to the vehicle's infotainment system. This operating status data includes the electric side tent's drive motor current data, temperature data, and / or sensor data. The vehicle's infotainment system determines whether a malfunction has occurred based on operational status data. When it is determined that at least one of the following faults has occurred: motor overload, communication interruption, sensor malfunction, or excessive temperature, the vehicle system generates a corresponding fault prompt message and displays the fault prompt message and / or solution prompt on the vehicle system screen.

[0064] Specifically, the system also includes fault diagnosis functionality. During operation, the electric side tent transmits real-time operational status data back to the vehicle's infotainment system. This data includes the electric side tent's drive motor current data, temperature data, and / or sensor data. The drive motor current data is collected in real-time by a current detection module (e.g., a Hall effect current sensor or sampling resistor) located in the motor drive circuit, reflecting the motor's current operating current value. The temperature data is collected in real-time by a temperature sensor located inside the electric side tent (e.g., near the drive motor or on the control circuit board), reflecting the current internal temperature. The sensor data includes detection data from various sensors built into the electric side tent, such as the actual opening / closing angle data detected by an angle sensor, and motor position or motion status data detected by a Hall effect sensor. The electric side tent collects the above operational status data at a preset sampling frequency (e.g., once every 100 milliseconds) and transmits it back to the vehicle's infotainment system in real-time via a wireless communication module.

[0065] After receiving the operating status data transmitted back by the electric side tent, the vehicle's infotainment system determines whether a fault has occurred based on this data. The system has built-in normal range thresholds for various operating status data and fault determination logic. By comparing the received operating status data with the corresponding normal range thresholds, it can determine whether a fault exists. When at least one fault is detected—motor overload, communication interruption, sensor malfunction, or excessively high temperature—the system generates a corresponding fault message and displays it on the vehicle's screen along with / or solution suggestions.

[0066] In response to motor overload faults, the vehicle's infotainment system compares the received drive motor current data with the preset maximum allowable current value. If the drive motor current exceeds the maximum allowable current value and persists for more than a preset time (e.g., more than 500 milliseconds), the system determines that a motor overload fault has occurred, indicating that the drive motor of the electric side tent is currently under excessive load, possibly caused by jamming of the side tent's movement mechanism, obstruction of the telescopic arm, or a fault in the motor itself. In this case, the system generates a corresponding fault message, such as "Motor overload, please check if the side tent's movement mechanism is jammed. If the problem cannot be resolved, please contact after-sales service," and displays this message on the vehicle's screen.

[0067] In response to communication interruption faults, the vehicle's infotainment system determines the communication link status based on whether it continuously receives operational status data from the electric side tent. If the system does not receive any operational status data or heartbeat signals from the electric side tent within a preset time (e.g., 5 seconds), a communication interruption fault is identified, indicating that the wireless communication link between the vehicle's infotainment system and the electric side tent has been broken. Communication interruptions may be caused by Bluetooth connection drops, electric side tent power failure, wireless signal interference, or communication module malfunctions. In this case, the infotainment system generates a corresponding fault message, such as "Communication interrupted, please check Bluetooth connection status or electric side tent power," and displays this message on the screen. During a communication interruption, because data communication between the vehicle's infotainment system and the electric side tent is impossible, the system cannot send any control commands to the tent via the wireless communication module. Therefore, while displaying the fault message, the system disables the electric side tent control buttons on the screen to prevent users from performing invalid operations during the communication interruption. Once the communication link is restored, the system automatically restores the operability of all control buttons.

[0068] In response to sensor malfunctions, the vehicle's infotainment system compares the received sensor data with a preset effective range. When the sensor data exceeds the preset effective range or exhibits significant and unreasonable changes (e.g., excessive fluctuations in angle sensor data, loss of Hall sensor data), the system determines a sensor malfunction has occurred. In this case, the system generates a corresponding fault message, such as "Angle sensor malfunction, please contact after-sales service," and displays this message on the vehicle's screen.

[0069] In response to overheating issues, the vehicle's infotainment system compares the received temperature data with a preset temperature threshold. If the temperature exceeds the threshold, the system determines an overheating fault, indicating that the internal temperature of the electric side tent is too high, potentially caused by prolonged high-load operation of the motor, excessively high ambient temperature, or poor heat dissipation. In this case, the system generates a corresponding fault message, such as "Motor overheating, please wait for it to cool down before trying again," and displays this message on the screen. Simultaneously, the system automatically pauses the current operation of the electric side tent, allowing the user to resume operation only after the temperature has returned to a safe range, preventing damage to the motor or electronic components from high temperatures.

[0070] When multiple faults exist simultaneously, the vehicle's infotainment system displays the corresponding prompts for each fault in a preset priority order, or displays all fault prompts simultaneously in a list format. Through these fault diagnosis functions, the system can monitor the operating status of the electric side tent in real time and provide users with clear fault prompts and solution suggestions when a fault occurs. This allows users to quickly understand the cause of the fault and take appropriate measures, effectively improving the system's maintainability and user safety.
