Description

TECHNICAL AREA The present application relates to the technical field of vehicles, in particular a method for scratch protection on vehicle doors, a device, a apparatus and a vehicle. STATE OF THE ART After parking a vehicle, scratching can easily occur when opening the door if the vehicle is too close to an obstacle or if the parking space is confined, causing the door to be too close to surrounding objects. Such scratching can lead to paint damage, rust, and corrosion in the affected areas. This affects the structural stability and safety of the vehicle doors and increases the vehicle's repair costs. To protect vehicle doors from scratches, binocular cameras or proximity sensors are now installed on both sides of the body. These cameras or sensors detect the presence of an object that could scratch the doors. This method allows for a rough detection of the obstacle causing scratches around the vehicle body by scanning the area on both sides. However, it does not solve the problem of scratches on the bottom of the doors.

A distance value between the bottom edge of the target door and the target obstacle is detected when the target door's opening angle changes.

DESCRIPTION OF THE EXECUTION FORMS To clarify the above and further features and advantages of this application, it is explained in more detail below in conjunction with the drawings. It should be understood that the specific embodiments provided here are for illustrative purposes only and are not limiting. The following description sets out numerous specific details to enable a thorough understanding of this application. However, it is obvious to those skilled in the art that this application can be implemented without these specific details. Under other circumstances, well-known steps or operations are not described in detail so as not to obscure this application. The existing method for scratch protection on vehicle doors cannot solve the problem of scratching on the underside of the vehicle doors. The risk of scratching remains. This is because the height difference between the vehicle doors and the curb was taken into account when the door height was determined. However, the investigation showed that when a passenger opens the vehicle door, the height on the side of the occupied seat is slightly reduced due to the passenger's weight. This reduces the height difference between the vehicle door and the curb. Consequently, the underside of the vehicle door can strike the curb and cause scratches. Therefore, this application proposes a method for scratch protection on vehicle doors. The method for scratch protection on vehicle doors proposed in this application can be implemented by the device for scratch protection on vehicle doors proposed in this application, which can be equipped in an electronic device. With reference to Fig. 1, the method proposed in this application for scratch protection on vehicle doors comprises the following steps S110 to S150. S110: Obtaining seat detection information from the vehicle to determine a destination door based on the seat detection information; wherein the seat detection information indicates whether the seat is occupied by a passenger. For example, seat detection information can include at least one of the following: pressure data corresponding to the seats, seat image data. Seat detection information can also include further data related to passenger occupancy detection, such as data from infrared sensors or temperature data from temperature sensors. Determining the destination door based on seat detection information can be achieved, for example, by analyzing the seat detection information to determine whether a seat is occupied by a passenger. The vehicle door adjacent to the occupied seat is then designated as the destination door. In other words, the destination door is the vehicle door next to the seat occupied by a passenger. S130: Activation of a distance measuring device of the corresponding target door to detect a distance value between the lower edge of the corresponding target door and the target obstacle when the opening angle of the target door changes. The opening angle refers to the angle at which the vehicle door opens. The change in the opening angle of a vehicle door encompasses the process from the closed state to the open state, as well as from an initial opening to full opening. The initial opening refers to the open state of the vehicle door, where it was initially at a specific opening angle. Full opening refers to the open state of the vehicle door at its maximum opening angle. When a passenger wants to exit the cabin, the destination door opens. During this process, the opening angle of the destination door gradually increases; that is, the opening angle of the destination door changes. Specifically, a further step for condition monitoring can be carried out before step S130: monitoring the condition and opening angle of the target door. Once the target door has been determined, its status is monitored. In other words, it is monitored whether the target door is open. If the vehicle door was initially closed, a change in its status from closed to open is monitored. This change in the opening angle is detected when a passenger exits the cabin, opens the originally closed target door using the interior door handle, or when someone outside the vehicle opens the originally closed target door using the exterior door handle. For example, the status of the corresponding vehicle door can be monitored by receiving a signal from the door opening detector. The door opening detector is designed to detect when the vehicle door is opened. The door opening detector could be, for example, an angle sensor, a switch sensor, or a photoelectric sensor on the vehicle door.With electronic vehicle doors, the door status can also be determined by monitoring the corresponding electronic signal. In the case of a target door with an initially defined opening angle, the opening angle can be further monitored by observing the open state to determine whether it changes. The target obstacle is an obstruction in the vicinity of the vehicle door, such as a curb. The smaller the distance between the bottom edge of the target door and the target obstacle, the more likely the bottom edge of the target door is to collide with the obstacle and cause a scrape. Specifically, the vehicle door next to a passenger-occupied seat is defined as the target door. By measuring the distance between the bottom edge of the target door, whose opening angle changes, and the target obstacle, the system accurately measures the distance between the vehicle door (whose height is reduced due to the passengers) and the obstacle. In particular, the distance measuring device is only activated when the opening angle of the target door changes. This saves energy. S150: Determine whether an operation to protect vehicle doors from scratches should be carried out, based on the distance value. Specifically, the system determines whether scratch protection for vehicle doors should be applied based on the distance value and a predefined threshold. The predefined threshold is determined by the distance at which scratching of vehicle doors is likely to occur. In particular, there is a risk of scratching if the distance is less than the predefined threshold. In this case, scratch protection should be applied. If the distance is greater than or equal to the predefined threshold, the risk of scratching is minimal, and therefore scratch protection should not be applied. Specifically, the anti-scratch operation for vehicle doors can be configured according to actual needs. For example, the anti-scratch operation for vehicle doors can include at least one of the following: operation with an alarm message and / or operation with locking of the vehicle door. In the operation with an alarm message, for example, a scratch warning can be issued in addition to the alarm, alerting the passenger to the risk of scratching. In the operation with locking of the vehicle door, for example, a locking command can be sent to lock the corresponding target door to prevent further opening and scratching. The above method for scratch protection on vehicle doors uses seat detection information, which indicates whether a seat is occupied by a passenger, to determine the target door. A distance value between the bottom edge of the target door and the target obstacle is detected when the target door's opening angle changes. This determines whether scratching on the bottom edge of the target door is necessary. By using the target door as the detection target, the risk of scratching on the underside (towards the ground) can be effectively identified, and the scratch protection operation can then be implemented. This efficiently solves the problem of scratch protection on the underside of the vehicle door.The risk of damage to passengers and vehicles is significantly reduced, the potential for accidents is minimized, and safety during vehicle operation is improved. Specifically, the vehicle door adjacent to a passenger seat is designated as the target door. In the above method for scratch protection on vehicle doors, the target door next to a passenger seat is defined as the detection target. This allows scratching to be effectively detected due to the reduced height of the target door caused by the passenger. The underside of the vehicle door next to the passenger can thus be efficiently protected from scratches, thereby increasing vehicle safety. In some embodiments, obtaining seat detection information from the vehicle further includes: receiving the original seat detection information captured and transmitted by the information acquisition device; preprocessing the original seat detection information into final seat detection information; and determining the target door based on the final seat detection information. The information acquisition device is designed to capture initial seat detection information. Examples include pressure sensors, vehicle cameras, or infrared sensors. Preprocessing includes, but is not limited to, noise reduction and data correction. Preprocessing the initial seat detection information improves data accuracy. In some embodiments, step S110 includes: obtaining pressure data of the vehicle seat, and determining a corresponding seat as the seat occupied by the passenger and a vehicle door adjacent to the corresponding seat as the destination door if the pressure data is greater than a predetermined pressure value. For example, data can be received from a pressure sensor located on the seat, and the pressure data of that seat can be obtained. In particular, a pressure sensor, as shown in Fig. 2, is located under the seat to determine the pressure generated by a passenger sitting on the seat. Obtaining pressure data from the vehicle seat further comprises: receiving the detected pressure data from the pressure sensor corresponding to the vehicle seat; and preprocessing the pressure data detected by the pressure sensor into final pressure data. Specifically, the pressure data of all seats in the vehicle can be obtained and compared with a predefined pressure value. An analysis of all seats identifies the seat occupied by a passenger. The vehicle door adjacent to the occupied seat is then set as the destination door. Alternatively, the pressure data of the seats on the side of the vehicle doors (the seats next to the doors) can be obtained and compared with the predefined pressure value. An analysis of the seats on the side of the vehicle doors identifies the seat occupied by a passenger and finally sets the destination door. Determining the destination door is simplified by identifying the seat occupied by a passenger using the seat pressure data and by analyzing it based on a size comparison. In further embodiments, step SII 0 comprises: obtaining seat image data of the vehicle, and determining a vehicle door adjacent to a corresponding seat as the target door, if the seat is recognized as the seat occupied by the passenger based on the seat image data. For example, vehicle seat image data can be obtained using a vehicle camera. This seat image data is then subjected to image recognition to identify seats with occupant images, i.e., seats occupied by passengers. In this way, the occupied seat is automatically identified using image recognition. The destination door is then determined. Specifically, obtaining vehicle seat image data further includes: receiving the seat image data sent by the vehicle camera, preprocessing the seat image data sent by the vehicle camera into final seat image data. It is understood that in other embodiments, the seat occupied by the passenger can also be determined by a combination of the seat pressure data and the seat image data. In that case, the vehicle door next to the seat occupied by the passenger can be defined as the destination door. In some embodiments, the procedure after step S130 and before step S150 further includes: preprocessing the detected distance value. Specifically, in step S170, based on the preprocessed distance value, it is determined whether an operation for scratch protection should be carried out on vehicle doors. The preprocessing of the recorded distance value includes, but is not limited to, filtering and noise reduction of the recorded distance value to improve the accuracy of the data. In some embodiments, step S130, activating a distance measuring device on the corresponding target door to detect a distance value between the bottom edge of the target door and the target obstacle, further includes: activating a distance measuring device on the underside of the corresponding target door to detect the distance value in the vertical direction, in order to detect the vertical distance between the bottom edge of the target door and the target obstacle. Thus, the distance value detected by the distance measuring device includes: the vertical distance between the bottom edge of the corresponding target door and the target obstacle. The height difference represents the vertical distance between the bottom edge of the target door and the target obstacle. Specifically, step S150 includes: issuing a scratch warning and / or sending a locking command to lock the corresponding target door if the height difference is less than a first threshold. It is understood that a scratch warning can be issued or a locking command sent to lock the corresponding target door if the height difference is less than a first threshold. Alternatively, both a scratch warning and a locking command to lock the corresponding target door can be issued. The "corresponding target door" refers to the target door whose opening angle changes and whose height difference between its bottom edge and the target obstacle is less than the first threshold. It is understood that the first threshold can be 0. The scratch warning is a notification designed to warn against scratching of vehicle doors. By issuing the scratch warning, the passenger is alerted to the risk of scratching the vehicle door. The passenger can therefore prevent the door from opening further. The scratch warning can be delivered via a voice announcement, the display of text or images on a screen, or an alarm sound, although this application is not limited to these methods. In particular, a locking command can be sent to the locking assembly. This controls the locking assembly to lock the corresponding target door. Locking the target door prevents further opening and thus prevents scratching. In some embodiments, step S130, activating a distance measuring device on the corresponding target door to detect a distance value between the bottom edge of the corresponding target door and the target obstacle, further comprises: activating a distance measuring device on the underside of the corresponding target door to detect the distance value in the horizontal direction, in order to detect the horizontal distance between the bottom edge of the target door and the target obstacle. Thus, the distance value detected by the distance measuring device includes: the horizontal distance between the bottom edge of the corresponding target door and the target obstacle. The horizontal distance is the distance in the horizontal direction, perpendicular to the vertical direction. By measuring both the vertical and horizontal distances, a distance analysis can be performed in both directions. Step S150 further includes: issuing a scratch warning and / or sending a locking command to lock the corresponding target door if the horizontal distance is less than the second threshold and the vertical distance is less than a first threshold. It is understood that the second threshold depends on the width of the door. Specifically, the first and second thresholds are determined based on the distance that could cause scratching. By comparing the vertical and horizontal distances with the corresponding thresholds, the potential scratching on the lower edge of the vehicle door is defined in both vertical and horizontal directions. This effectively prevents scratching on the vehicle doors and increases safety when opening them. It is understood that a scratch warning can be issued, or a locking command can be sent to lock the corresponding target door, or both a scratch warning and a locking command can be sent to lock the corresponding target door if the horizontal distance is less than the second threshold and the vertical distance is less than the first threshold. In some embodiments, step S130, activating a distance measuring device of the corresponding target door to detect a distance value between the lower edge of the corresponding target door and the target obstacle, further comprises: activating at least two distance measuring devices arranged at different locations on the underside of the target door to detect the distance value between the lower edge of the corresponding target door and the target obstacle. The at least two distance measuring devices, positioned at different points on the underside of the target door, can each measure the distance to the target obstacle at various locations. This allows for the use of measurements from multiple points to determine whether scratch protection measures should be applied to the vehicle doors. This results in improved scratch protection. In particular, a first distance measuring device for measuring the vertical distance and a second distance measuring device for measuring the horizontal distance at the bottom edge of the target door can be provided. Furthermore, the number of first and second distance measuring devices is unlimited. To improve measurement accuracy, multiple first / second distance measuring devices can be provided. In some embodiments, the distance measuring device includes, but is not limited to, one of the following: ultrasonic distance measuring sensor, infrared distance measuring sensor, laser distance measuring sensor and millimeter wave radar sensor. Specifically, the distance measuring device can be positioned at the bottom edge of the target door. This allows the vertical distance to the target obstacle to be measured precisely, for example, using an ultrasonic distance sensor. The placement of the ultrasonic distance sensor is shown in Fig. 3. An example of this is the acquisition of pressure data from the seat using a pressure sensor and the acquisition of a distance value between the underside of the vehicle door and the curb using an ultrasonic distance sensor. Referring to Figure 4, the data acquired by the pressure sensor on the seat is preprocessed after acquisition, including noise reduction and correction of the sensor values. Based on the preprocessed data, the weight corresponding to the pressure is calculated and compared with the set value. Using the comparison result, the seat occupied by a passenger is determined in order to locate the target seat. When the vehicle door next to the target seat is opened, the ultrasonic distance sensor on the underside of this door is activated to acquire data. After preprocessing the acquired ultrasonic data, a distance is calculated.If the distance is less than the threshold, there is a potential risk of scratching. An alarm is then triggered and the vehicle door locks. Data acquisition, preprocessing, calculation, and real-time safety monitoring efficiently prevent the underside of the vehicle door from impacting the curb. An alarm is triggered in time to warn the passenger and driver, ensuring driving safety. Furthermore, the impact protection against the curb is detected and automatically controlled. The entire process is fully automated, eliminating the need for the passenger to take any additional action or pay attention. This improves passenger comfort and eliminates the worry of the vehicle door hitting the curb. This application proposes a device for scratch protection on vehicle doors. With reference to Fig. 5, the device comprises a seat detection module 510, a distance detection module 530, and a scratch protection module 550.

In some embodiments, the seat detection module 510 is further configured to receive the original seat detection information captured and transmitted by the information acquisition device, preprocess the original seat detection information to final seat detection information, and determine the destination door based on the final seat detection information. In some embodiments, the seat detection module 510 is further configured to receive the pressure data of the vehicle seat and to determine a corresponding seat as the seat occupied by the passenger and the vehicle door adjacent to the corresponding seat as the destination door when the pressure data is greater than a predetermined pressure value.

In particular, the scratch protection module 570 determines, based on the preprocessed distance value, whether a scratch protection operation should be performed on the vehicle doors. In some embodiments, the distance detection module 530 is further configured to activate a distance sensor on the underside of the corresponding target door to detect a distance value in the vertical direction, in order to obtain a vertical distance between the underside of the target door and the target obstacle.

The scratch protection module 550 is further configured to issue a scratch warning and / or send a locking command to lock the corresponding target door if the vertical distance is less than a first threshold value. In some embodiments, the distance detection module 530 is further configured to activate a distance sensor on the underside of the corresponding target door to detect a horizontal distance value in order to obtain a horizontal distance between the underside of the target door and the target obstacle.
