Description

Technical Field

[0001] This application relates to the field of vehicle windshield wiper technology, specifically to a vehicle. Background Technology

[0002] In modern automotive design, the relative spatial relationship between the hood and the windshield wiper system is becoming increasingly compact. This results in an overlap between the opening motion envelope of the hood and the wiping motion envelope of the windshield wipers, creating a risk of interference. When the vehicle is with the hood open, such as during vehicle inspections or adding fluids, if the user accidentally activates the wipers, the wiper arms are highly likely to collide with the open hood, potentially leading to wiper arm breakage, damage to the wiper motor, or damage to the hood's paint. Utility Model Content

[0003] This application provides a vehicle that can control the windshield wipers to return to their original position and disable them when the hood is detected to be open, thereby preventing the windshield wipers from colliding with the hood and effectively preventing the windshield wipers from being damaged by the hood when it is open.

[0004] In a first aspect, a vehicle is provided, comprising: a detection module, a control module, and a windshield wiper. The detection module is electrically connected to the control module, and the control module is electrically connected to the windshield wiper. The detection module is used to send an opening signal to the control module when an opening signal of the hood is detected. The control module is used to control the windshield wiper to move to the return position and disable the windshield wiper when the opening signal is received.

[0005] As described above, this embodiment of the application uses a detection module to sense the opening and closing state of the hood. When the hood is detected to be open, the control module automatically controls the wipers to return to their original position and disables them. This effectively avoids collisions between the wipers and the hood, thus preventing damage to the wipers due to pressure from the hood when it is open. It also avoids problems such as windshield breakage and hood damage.

[0006] Optionally, the detection module includes: a physical switch, which is located on the edge of the front hood; the physical switch is closed when the front hood is closed and open when the front hood is open; when the physical switch is open, the physical switch generates an open signal, which is an electrical level signal.

[0007] As described above, this embodiment of the application, by installing a physical switch at the leading edge of the front hood, effectively utilizes the direct contact between the hood and the physical switch during opening and closing to achieve accurate sensing of the opening and closing state, ensuring the timeliness and reliability of signal detection. The physical switch has a simple structure, low cost, and strong anti-interference capability. Even during long-term vehicle use, it maintains stable detection accuracy, providing a reliable prerequisite for subsequent operations such as wiper repositioning and disabling.

[0008] Optionally, the detection module includes: a photoelectric sensor disposed on the edge of the front hood; the photoelectric sensor includes a transmitter and a receiver disposed opposite to each other, the transmitter being used to emit a detection beam and the receiver being used to receive the detection beam; when the front hood is closed, the receiver does not receive the detection beam, and when the front hood is open, the receiver receives the detection beam; when the receiver receives the detection beam, the photoelectric sensor generates an activation signal, which is an electrical level signal.

[0009] As described above, this embodiment of the application utilizes a photoelectric sensor installed on the edge of the front hood to accurately identify the opening and closing state of the hood by controlling the continuity of the optical path. When the hood is open, the obstruction is removed, the receiver immediately receives the detection beam, and the sensor outputs a clear high-level signal, avoiding misjudgments caused by poor contact or delayed rebound of mechanical switches. This detection method features clear state distinction, timely response, and no intermediate ambiguity, significantly improving the accuracy of hood opening signal recognition.

[0010] Optionally, the detection module includes: a pressure sensor disposed on the edge of the front hood; when the hood is closed, the pressure value applied by the hood to the pressure sensor is greater than or equal to a preset pressure threshold; when the hood is open, the pressure value detected by the pressure sensor is less than the preset pressure threshold; when the pressure value is less than the preset pressure threshold, the pressure sensor generates an opening signal, which is an electrical level signal.

[0011] As described above, this embodiment of the application, by setting a pressure sensor on the edge of the front hood cover, can accurately detect pressure changes during the opening and closing of the hood, achieving high-precision judgment of the opening and closing state. Using the comparison of the pressure value with a preset pressure threshold as the state criterion can effectively improve the accuracy and reliability of the detection results.

[0012] Optionally, the vehicle also includes: a distance sensor, which is disposed on the edge of the front hood; the distance sensor is used to measure the distance between the edge of the front hood and the front hood, and send the distance to the control module; the control module is also used to compare the distance with a preset distance when it receives the activation signal and the distance, and if the distance is greater than the preset distance, control the wipers to move to the return position and disable the wipers.

[0013] As can be seen from the above description, the embodiments of this application can effectively avoid false control caused by false triggering of the detection module (such as vibration causing the switch to disconnect momentarily), and significantly improve the accuracy and reliability of vehicle judgment by introducing a preset distance as a judgment condition.

[0014] Optionally, the vehicle also includes a vehicle speed sensor; the vehicle speed sensor is used to send the vehicle speed to the control module; the control module is also used to keep the hood closed and control the windshield wipers to continue moving if the wipers are in motion and the vehicle speed is greater than a preset speed, upon receiving an activation signal and vehicle speed.

[0015] As can be seen from the above description, the embodiments of this application effectively distinguish between different working conditions such as normal vehicle driving and low-speed parking by introducing a vehicle speed sensor. When a high vehicle speed is detected, the hood opening signal can be intelligently identified as a false trigger or abnormal operation, and priority is given to ensuring driving safety and basic functions. This avoids endangering driving safety due to the sudden disabling of the windshield wipers in critical scenarios such as rainy days, thereby improving the accuracy of vehicle judgment and the safety of use.

[0016] Optionally, the control module includes: a vehicle controller and a wiper controller; the vehicle controller is used to receive an activation signal and send the activation signal to the wiper controller; the wiper controller is used to receive the activation signal sent by the vehicle control module, control the wipers to move to the return position, and disable the wipers.

[0017] As can be seen from the above description, the embodiments of this application divide the control module into a vehicle controller and a windshield wiper controller. The vehicle controller performs unified perception and logical judgment of the vehicle status, and the windshield wiper controller performs specific operations, thereby realizing a reasonable division of labor and efficient collaboration of control functions.

[0018] Optionally, the vehicle also includes a prompting module, which is electrically connected to the control module; the control module is also used to control the prompting module to output a prompting message when the windshield wipers are moved to the return position, the prompting message being used to remind the user that the front hood must be closed before the windshield wipers can be used.

[0019] As can be seen from the above description, the embodiments of this application, while ensuring safety control, promptly provide feedback on the vehicle status to the user, enhance the transparency of human-computer interaction, prevent the user from repeatedly operating the wiper switch due to ignorance, and improve the user experience and the overall vehicle intelligence level.

[0020] Optionally, the detection module is used to send a closing signal to the control module when a closing signal of the front hood is detected; the control module is also used to deactivate the windshield wipers upon receiving the closing signal.

[0021] As described above, this embodiment of the application automatically unlocks the windshield wipers after detecting that the hood is closed, thus automatically restoring the function. This process requires no manual intervention, features a closed-loop logic, and responds promptly, ensuring the effectiveness of safety control while improving ease of use and human-machine interaction, thereby enhancing the vehicle's intelligence level.

[0022] Optionally, the control module is also used to control the windshield wipers to return to normal operation if it detects that the windshield is closed when it receives a signal that the hood is open and the wipers have not moved to the return position.

[0023] As can be seen from the above description, the embodiments of this application avoid interruption of the wiper function due to brief misoperation, thereby improving the accuracy of the vehicle's response to user intentions and the ease of use. Attached Figure Description

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

When the combination of technical solutions is contradictory or impossible to implement, it should be considered that such a combination of technical solutions does not exist and is not within the scope of protection claimed by this utility model.

[0030] In modern automotive design, the relative spatial relationship between the hood and the windshield wiper system is becoming increasingly compact. This results in an overlap between the opening motion envelope of the hood and the wiping motion envelope of the windshield wipers, creating a risk of interference. When the vehicle is with the hood open, such as during vehicle inspections or adding fluids, if the user accidentally activates the wipers, the wiper arms are highly likely to collide with the open hood, potentially leading to wiper arm breakage, damage to the wiper motor, or damage to the hood's paint.

[0031] To address the aforementioned issues, this application provides a vehicle that can control the windshield wipers to return to their original position and disable them when the hood is detected to be open, thereby preventing the wipers from colliding with the hood and effectively preventing the wipers from being damaged by the hood when it is open.

[0032] The following is a detailed description of a vehicle provided in an embodiment of this application.

[0033] Figure 1 This application provides a schematic diagram of the structure of a vehicle according to an embodiment of the present application. Figure 1As shown, the vehicle 100 includes a detection module 110, a control module 120, and a windshield wiper 130. The detection module 110 is electrically connected to the control module 120, and the control module 120 is electrically connected to the windshield wiper 130.

[0034] The detection module 110 is used to send an opening signal to the control module 120 when an opening signal of the front hood is detected; the control module 120 is used to control the wiper 130 to move to the return position and disable the wiper 130 when the opening signal is received.

[0035] The detection module refers to a hardware device or sensing unit capable of sensing or determining whether the hood is open. Specifically, the detection module can be located at the edge of the hood panel, the hinge area, near the lock body, or other structural positions related to the movement of the hood, sensing its open / closed state through physical contact or non-contact methods. When the hood is closed, its leading edge is in contact with the vehicle body structure, applying pressure to the detection module or blocking the light path, maintaining it in a first operating state. When the hood is opened, the contact relationship is released, the pressure on the detection module disappears, or the sensing signal changes, thereby switching to a second operating state and outputting an open signal in the form of a high-level or low-level signal.

[0036] Optionally, the detection module can also determine the occurrence of a hood opening action by receiving a position feedback signal, unlocking execution signal, or control command from the hood lock motor. For example, when a user triggers the hood opening operation via the central control touchscreen, remote key, or mobile application, the vehicle controller issues an unlocking command. Simultaneously, as this unlocking command drives the relevant actuator (such as the hood lock motor) to perform the unlocking action, the unlocking command or the action signal fed back by the actuator can be identified as an opening signal representing the hood opening, and transmitted to the control module, thereby triggering the subsequent wiper return and disabling process. In this implementation, the detection module can include a position sensor, current detection circuit, or communication interface module inside the lock body, achieving the same detection effect without relying on a traditional mechanical pressure block structure.

[0037] The control module refers to an electronic control unit with signal reception, logic judgment, and execution control functions. Specifically, after receiving the activation signal from the detection module, the control module generates a corresponding control command and outputs it to the wiper drive unit. Responding to this command, the drive unit first determines the current state of the wipers: if the wipers are in motion, it controls the wiper motor to perform a return action, precisely returning them to the initial safe position (i.e., the return position) at the bottom edge of the windshield; if the wipers are already in the return position, the current state remains unchanged. After confirming that the wipers have reached the return position (or directly determining if they are already in the return position), the drive unit immediately locks the motor control signal, disabling wiper operation by cutting off or blocking subsequent operation commands, ensuring that the wipers do not perform unexpected actions when the hood is open.

[0038] This application embodiment uses a detection module to sense the opening and closing status of the hood. When the hood is detected to be open, the control module automatically controls the wipers to return to their original position and disables them. This effectively avoids collisions between the wipers and the hood, thus preventing damage to the wipers due to pressure from the hood when it is open. It also avoids problems such as windshield breakage and hood damage.

[0039] like Figure 2 As shown, Figure 2 The diagram illustrates an application scenario of a vehicle according to an embodiment of this application. The leading edge of the front hood shown in the diagram is typically the area where the detection module is located. This position is located at the front of the vehicle body and is the position that directly contacts the hood when it is closed. It is also the key position where the hood first disengages from its closed state during the opening process.

[0040] In one possible implementation, the detection module includes: a physical switch disposed on the edge of the front hood; the physical switch is closed when the hood is closed and open when the hood is open; when the physical switch is open, the physical switch generates an open signal, which is an electrical level signal.

[0041] Specifically, such as Figure 3 As shown, Figure 3This diagram illustrates the structure of a physical switch according to an embodiment of this application. The physical switch includes a pressure block E, disposed on the top of the switch; F, a metal conductive sheet at the bottom of the pressure block, integrally connected to or fixedly installed with the pressure block, serving as part of the moving contact; a spring G, located below the pressure block, providing a reset force so that the pressure block automatically rebounds when no external force is applied; stationary contacts A and B are fixed to the switch base, cooperating with the metal conductive sheet F to form openable or closed circuit contacts; C and D are lead wires, one end of wire C connected to stationary contact A, and the other end connected to the signal input terminal of the control module; one end of wire D connected to stationary contact B, and the other end connected to the ground terminal. It is worth noting that, as... Figure 4 As shown, Figure 4 The illustration shows an application scenario diagram of a vehicle provided by an embodiment of this application. The physical switch can be installed at the edge H of the front hood cover. When the spring G is not compressed (i.e. the front hood is open), the top of the pressure block E is higher than the edge plane of the front hood cover.

[0042] When the hood is closed, the inner panel of the front hood applies pressure to the physical switch mounted on the edge of the front hood cover. This pressure causes the pressure block E to compress the spring G, which in turn moves the conductive metal plate F downwards. The conductive metal plate F then simultaneously contacts the stationary contacts A and B, thus completing the circuit and closing the physical switch. At this time, the control module receives a low-level signal through wire C, the internal contacts of the switch, and wire D, indicating that the physical switch is closed.

[0043] As the hood begins to open, even if only slightly, creating a tiny gap, as soon as the pressure on the pressure block E from the inner hood panel is released, the spring G immediately resets, pushing the pressure block E and the metal conductive plate F upwards. Because this physical switch is highly sensitive, when the pressure block E begins to rebound due to pressure release, and its upward displacement reaches the critical value required for contact separation, the moving contact F quickly separates from the stationary contacts A and B, and the circuit is immediately broken, meaning the physical switch is open. At this time, the signal input terminal of the control module becomes a high-level signal due to its internal or external pull-up resistor, and this high-level signal is recognized as the opening signal.

[0044] In this embodiment, by installing a physical switch at the leading edge of the front hood, the direct contact between the hood and the physical switch during opening and closing can be effectively utilized to achieve accurate sensing of the opening and closing status, ensuring the timeliness and reliability of signal detection. The physical switch has a simple structure, low cost, and strong anti-interference capability. Even during long-term vehicle use, it maintains stable detection accuracy, providing a reliable prerequisite for subsequent operations such as wiper repositioning and disabling.

[0045] In one possible implementation, the detection module includes: a photoelectric sensor disposed on the edge of the front hood; the photoelectric sensor includes a transmitter and a receiver disposed opposite to each other, the transmitter being used to emit a detection beam and the receiver being used to receive the detection beam; when the front hood is closed, the receiver does not receive the detection beam, and when the front hood is open, the receiver receives the detection beam; when the receiver receives the detection beam, the photoelectric sensor generates an activation signal, which is an electrical level signal.

[0046] Specifically, the photoelectric sensor can be a through-beam photoelectric switch, with its transmitter and receiver positioned opposite each other, respectively mounted on both sides of the edge of the front fascia cover. For example... Figure 4 As shown, the transmitter of the photoelectric sensor can be installed at edge I of the front hood cover, and the receiver can be installed at edge K of the front hood cover. The optical paths of the two are aligned to ensure that the detection beam emitted by the transmitter can be accurately transmitted to the receiver, forming a continuous optical path.

[0047] When the hood is closed, the leading edge of the front hood (see...) Figure 2 The hood is tightly fitted to the edge of the front hood panel, with its leading edge positioned precisely in the optical path between the transmitter and receiver. This physically blocks the detection beam, preventing its transmission and ensuring the receiver cannot receive the signal. In this state, the photoelectric sensor outputs a low-level signal to indicate the hood is closed. When the hood is opened upwards, its leading edge moves away from the optical path obstruction, allowing the detection beam emitted by the transmitter to travel unimpeded to the receiver. Upon receiving the beam signal, the receiver triggers a level shift in the photoelectric sensor's internal circuitry, generating and outputting a high-level activation signal. This high-level signal is transmitted to the control module as the basis for determining whether to activate or disable the wipers.

[0048] This embodiment of the application utilizes a photoelectric sensor installed on the edge of the front hood to accurately identify the opening and closing state of the hood by controlling the continuity of the optical path. When the hood is open, the obstruction is removed, the receiver immediately receives the detection beam, and the sensor outputs a clear high-level signal, avoiding misjudgments caused by poor contact or delayed rebound of mechanical switches. This detection method features clear state distinction, timely response, and no intermediate ambiguity, significantly improving the accuracy of hood opening signal recognition.

[0049] In one possible implementation, the detection module includes: a pressure sensor disposed on the edge of the front hood; when the hood is closed, the pressure value applied by the hood to the pressure sensor is greater than or equal to a preset pressure threshold; when the hood is open, the pressure value detected by the pressure sensor is less than the preset pressure threshold; when the pressure value is less than the preset pressure threshold, the pressure sensor generates an opening signal, which is an electrical level signal.

[0050] The preset pressure threshold refers to the critical pressure value used to determine whether the hood is in a closed state. Specifically, such as... Figure 4 As shown, the pressure sensor can be installed at the edge J of the front hood cover to detect the pressure applied by the hood when it is closed.

[0051] With the hood closed, the leading edge of the hood presses down to fit tightly against the front cover, applying pressure to the pressure sensor consisting of its own weight and the preload of the locking mechanism. When this pressure value is greater than or equal to a preset threshold, the pressure sensor generates a low-level signal, indicating that the hood is closed. As the hood is lifted, the pressure is gradually released. When the pressure value is detected to be less than the preset pressure threshold, the pressure sensor generates a high-level opening signal, indicating that the hood is open.

[0052] For example, a preset pressure threshold can be set to 8N to determine whether the hood is closed. Assuming the vehicle is under maintenance, a technician opens the hood from its closed position. Initially, the hood is tightly pressed against the pressure sensor, detecting a pressure of 12N (greater than the 8N threshold), and the sensor outputs a low-level signal. When the opening angle reaches 3°, the pressure drops to 6N (less than the 8N threshold), and the sensor immediately outputs a high-level opening signal.

[0053] In this embodiment, by setting a pressure sensor on the edge of the front hood cover, pressure changes during the opening and closing of the hood can be accurately detected, achieving high-precision judgment of the opening and closing state. Using the comparison of the pressure value with a preset pressure threshold as the state criterion can effectively improve the accuracy and reliability of the detection results.

[0054] In one possible implementation, the vehicle also includes a ranging sensor, which is disposed on the edge of the front bulkhead cover. The distance sensor is used to measure the distance between the edge of the front hood and the front hood, and sends the distance to the control module. The control module is also used to compare the distance with a preset distance when it receives an activation signal and a distance. If the distance is greater than the preset distance, it controls the wipers to move to the return position and disables the wipers.

[0055] The preset distance is less than the actual distance corresponding to the hood opening to a safe angle, ensuring that the vehicle can trigger the windshield wipers as soon as the hood begins to open and before it is fully raised to the interference zone. The interference zone refers to the area where the motion envelope of the hood and the motion envelope of the windshield wipers overlap during the opening process, i.e., the risk area where the wiper arms may physically contact or collide with the hood when they swing.

[0056] Specifically, the ranging sensor can be an infrared ranging sensor or an ultrasonic ranging sensor, installed on the edge of the front hood. It continuously emits a detection signal (infrared beam or ultrasonic wave) at a specific frequency to the inside of the hood. The detection signal is reflected back to the ranging sensor after encountering the inner surface of the hood. By calculating the time difference between the transmission and reception of the detection signal, and combining it with the speed of signal propagation in the air, the real-time distance between the edge of the front hood and the hood can be accurately calculated.

[0057] When the vehicle's hood is fully closed, the distance is at its minimum, and the ranging sensor continuously outputs a stable near-range signal. When the hood is opened, as the opening angle increases, the inner surface of the hood gradually moves away from the sensor, and the measured distance increases accordingly. The ranging sensor converts the real-time distance data into analog or digital electrical signals, which are continuously transmitted to the control module.

[0058] After receiving the opening signal generated by the detection module, the control module further combines the distance information sent by the distance sensor to make a comprehensive judgment: if the measured distance is greater than the preset distance (e.g., 30mm), it confirms that the front hood has been truly opened and disengaged from the closed position, and then controls the wipers to perform the return action and disables the operation function.

[0059] This application embodiment introduces a preset distance as a judgment condition, which can effectively avoid false control caused by false triggering of the detection module (such as vibration causing the switch to disconnect momentarily), and significantly improve the accuracy and reliability of vehicle judgment.

[0060] In one possible implementation, the vehicle also includes a vehicle speed sensor; the vehicle speed sensor is used to send the vehicle speed to the control module; The control module is also used to keep the hood closed and control the wipers to continue moving if the wipers are in motion and the vehicle speed is greater than the preset speed, upon receiving an activation signal and vehicle speed.

[0061] The preset vehicle speed refers to the critical speed value used to determine whether the vehicle is in a normal driving state. Specifically, the vehicle speed sensor collects the wheel rotation speed in real time, converts the rotation speed into corresponding vehicle speed data through internal signal processing circuitry, and transmits the vehicle speed data to the control module. After receiving the hood opening signal from the detection module, the control module first retrieves the latest vehicle speed data transmitted by the vehicle speed sensor, and simultaneously determines whether the wipers are in motion through the current feedback signal of the wiper motor. If the wipers are detected to be in motion (e.g., high-speed wiping mode in rainy weather), and the real-time vehicle speed is greater than the preset speed (e.g., 3 km / h), the control module will determine that the current situation is a normal driving scenario, and the hood opening signal is likely to be falsely triggered (e.g., a brief malfunction in the detection module due to a bumpy road surface) or due to abnormal operation (e.g., accidentally touching the hood opening handle while driving). In this case, the control module will lock the hood, keeping it closed, and will also maintain the current working mode of the wipers to ensure that visibility is not affected in rainy or other scenarios.

[0062] For example, if a vehicle is traveling at 60 km / h in the rain with the windshield wipers in high-speed mode, the hood detection module briefly outputs an open signal due to road bumps. Upon receiving this signal, the control module detects that the real-time vehicle speed (60 km / h) is significantly higher than the preset speed (3 km / h) and the wipers are still in motion. It immediately determines this as a false trigger and controls the hood locking mechanism to remain locked while allowing the wipers to continue operating. Conversely, if the vehicle is in power mode and traveling at 2 km / h (below the preset speed), and the windshield wipers are in any of the following states: intermittent mode, washer-linked wiping, low speed, high speed, automatic wiper mode, or maintenance mode, and a hood open signal is detected, the control module determines that the user has intentionally opened the hood and immediately performs wiper reset and disabling operations to avoid interference risks.

[0063] This application embodiment introduces a vehicle speed sensor to effectively distinguish between different operating conditions such as normal vehicle driving and low-speed parking. When a high vehicle speed is detected, it can intelligently identify whether the hood opening signal is a false trigger or abnormal operation, and prioritize ensuring driving safety and basic functions. This avoids endangering driving safety due to the sudden disabling of the windshield wipers in critical scenarios such as rainy days, thereby improving the accuracy of vehicle judgment and the safety of use.

[0064] In one possible implementation, the control module includes: a vehicle controller and a wiper controller; the vehicle controller is used to receive an activation signal and send the activation signal to the wiper controller; The wiper controller receives the activation signal from the vehicle control module, controls the wipers to move to the return position, and disables the wipers.

[0065] Specifically, the vehicle controller, as the core control unit of the vehicle, receives the hood opening signal from the detection module in real time and determines the validity of the signal. After confirming the signal is valid, the vehicle controller forwards the opening command to the wiper controller. Upon receiving the command, the wiper controller immediately activates its internal control logic, driving the wiper motor to perform a return action, moving the wiper arm to the initial parking position at the bottom of the windshield; after the return is completed, the controller locks the wiper system, blocking operation signals from the wiper switch, thus disabling the function.

[0066] This application embodiment divides the control module into a vehicle controller and a windshield wiper controller. The vehicle controller performs unified perception and logical judgment of the vehicle status, and the windshield wiper controller performs specific operations, thus realizing a reasonable division of labor and efficient collaboration of control functions.

[0067] In one possible implementation, the vehicle also includes a notification module, which is electrically connected to the control module; The control module is also used to control the prompt module to output a prompt message when the wipers are moved to the return position. The prompt message is used to remind the user that the front hood must be closed before the wipers can be used.

[0068] Specifically, the prompt module can be integrated into the vehicle's human-machine interface system, such as the instrument panel display, central touchscreen, or in-vehicle voice prompt system. After the control module completes the control of the windshield wipers' return and disabling, it generates a specific prompt command and sends it to the prompt module. If the prompt module is a display screen, the control command will trigger the screen to display a specific warning icon or text message (e.g., "Hood open, wipers disabled"); if the prompt module is a voice prompt system, the control command will trigger the playback of pre-recorded voice reminders (e.g., "Hood not closed, wipers temporarily unavailable"). The prompt message continues to be output until the control module receives a signal indicating that the hood is closed and confirms it, at which point the prompt automatically terminates and the wipers resume normal function.

[0069] This application embodiment ensures safety control while providing timely feedback on vehicle status to the user, enhancing the transparency of human-machine interaction, preventing users from repeatedly operating the wiper switch due to ignorance, and improving the user experience and the overall vehicle intelligence level.

[0070] In one possible implementation, the detection module is used to send a closing signal to the control module when a closing signal of the front hood is detected; The control module is also used to deactivate the windshield wipers upon receiving a shutdown signal.

[0071] Specifically, when the hood returns from an open state to a fully closed state, the detection module senses the state change in real time and generates a corresponding shutdown signal. For example, if the detection module uses a physical switch, the downward pressure when the hood closes will drive the internal contacts to close, outputting a low-level signal as a shutdown signal; if it is a photoelectric sensor, the hood blocks the light path, causing the receiver to lose light, and similarly outputs a low-level signal as a shutdown signal; if it is a pressure sensor, the low-level signal output when the detected pressure value exceeds a preset threshold is used as a shutdown signal. The shutdown signal is sent to the control module, which, upon receiving the shutdown signal, immediately executes the recovery logic: first, it releases the circuit lock on the wiper control signal, enabling it to respond to wiper switch operation commands again; simultaneously, it can selectively control the prompt module to stop outputting relevant warning information.

[0072] In this embodiment, upon detecting that the hood is closed, the windshield wipers are automatically deactivated, restoring their functionality automatically. This process requires no manual intervention, features a closed-loop logic, and responds promptly, ensuring the effectiveness of safety control while improving ease of use and human-machine interaction, thus enhancing the vehicle's intelligence level.

[0073] In one possible implementation, the control module is also used to control the windshield wipers to return to normal operation if it detects that the windshield is closed when it receives a signal that the hood is open and the wipers have not moved to the return position.

[0074] Specifically, when the control module receives a signal that the hood is open, it immediately initiates the wiper return and disable control logic, driving the wiper motor to move to the return position. However, if the detection module sends a signal that the hood is closed again before the wipers have completed their return process, it indicates that the user may have briefly opened and then immediately closed the hood again. In this case, the control module interrupts the ongoing wiper return process, no longer forcibly moving the wipers to the return position or executing the disable command, but instead determines that the current state has returned to normal driving conditions. The control module then sends a recovery command to the wiper controller, canceling the original disable operation and maintaining or restoring the original operating mode of the wipers (such as low-speed wiping or high-speed wiping). For example, if the wipers were in high-speed wiping mode before the return action was initiated, the control module will re-output the high-speed drive signal, causing the wipers to return to their original operating state and continue running.

[0075] The embodiments of this application avoid interruption of the wiper function due to brief misoperation, thereby improving the accuracy of the vehicle's response to user intentions and the ease of use.
