Description

Technical Field

[0001] The embodiments of the present application relate to the technical field of vehicle control, and particularly to a door control method, device and vehicle based on a welcome light carpet. Background Art

[0002] With the development of vehicle intelligence, the automatic door opening and closing technology has gradually become an important direction for improving the user experience and safety. This technology realizes the automatic opening and closing of the vehicle door through the coordinated work of sensors, actuators and control systems, reducing the inconvenience of manual operation, and having significant advantages especially in the case of inconvenient hands or limited space. At the same time, the welcome function can enhance the luxury and brand image of the vehicle, and enhance the sense of ceremony of getting on and off the vehicle, becoming an important configuration for improving the user experience and market competitiveness.

[0003] Currently, the automatic door opening and closing technology of vehicles on the market is mainly realized through devices and apparatuses such as proximity sensors, gesture recognition sensors, electric motors or hydraulic systems, and electronic control modules. Among them, the proximity sensor is used to detect the action of a person approaching the vehicle, the gesture recognition sensor (such as a camera or an infrared sensor) can capture the gesture instructions of the person, the electric motor or the hydraulic system is used as a power device to drive the opening and closing of the vehicle door, and the electronic control module (Electronic Control Unit, ECU) is responsible for processing the sensor signals and controlling the operation of the actuator. When a person approaches the vehicle with a key or a mobile phone, the proximity sensor detects the signal and sends it to the ECU, and the ECU triggers the electric motor or the hydraulic system, and the vehicle door automatically opens; after the person enters the vehicle, a door closing signal is sent through an in-vehicle button, a gesture instruction or a mobile phone APP, and the ECU controls the actuator to close the vehicle door smoothly. The whole process is completed by the coordinated work of the sensor, the actuator and the control system.

[0004] The above method has the following deficiencies and defects: First, it cannot achieve a user-unnoticed entry. The user needs to deliberately make a specified behavior, and the user needs to stay in front of the vehicle for a period of time before the vehicle door will open. Second, it cannot create a welcome atmosphere, and it can only be used as a tool for the user, unable to bring a sense of dignity and ceremony to the user. Finally, for gesture-based door opening on the market, it can only be used when the user's hands are free, which is extremely inconvenient for users with occupied hands, and with a single triggering method, the false triggering rate is relatively high.

[0045] To make the objectives, technical solutions, and advantages of the present application clearer, the following will further describe the embodiments of the present application in detail with reference to the accompanying drawings.

[0046] It should be noted that the following detailed descriptions are all illustrative and are intended to illustrate the present application in some embodiments. Unless otherwise specified, all technical and scientific terms used herein have the same meaning as commonly understood by those of ordinary skill in the technical field to which the present application belongs.

[0047] It should be noted that the terms used herein are only for describing specific implementation modes and are not intended to limit the exemplary implementation modes according to the present application. As used herein, unless the context clearly indicates otherwise, the singular form is also intended to include the plural form. In addition, it should be understood that when the terms "include" and / or "comprise" are used in this specification, they indicate the presence of features, steps, operations, devices, components, and / or combinations thereof.

[0048] The embodiment of the present application provides a door control method based on a welcome light carpet. The implementation environment includes: a vehicle system, a detection module, a detection module control system, a light carpet, a light carpet control system, a light sensor, and an electric motor or a hydraulic system.

[0049] Among them, the detection module includes a sleep mode, a daytime mode, and a nighttime mode. When the detection module is in the daytime mode, it is used to judge whether it is a valid trigger signal for opening or closing the door by monitoring the behavior and approaching / leaving trend of a person within a specific range; when the detection module is in the nighttime mode, it is used to judge whether it is a valid trigger signal for opening or closing the door by monitoring the behavior of a person within a specific range; when the detection module is in the sleep mode, it does not monitor the person.

[0050] The detection module control system is used to control the detection mode of the detection module.

[0051] The light carpet includes a sleep mode and an on mode. When the light carpet is in the sleep mode, the light carpet is not lit; when the light carpet is in the on mode, a welcome light carpet is projected at the door.

[0052] The light carpet control system is used to control the light carpet mode and the dynamic change of the interaction between the light carpet and the user.

[0053] The light sensor is used to obtain the environmental brightness signal of the vehicle's environment, and then determine whether the vehicle's environment is daytime or nighttime according to the environmental brightness signal.

[0054] The electric motor or hydraulic system is used to drive the door to open or close.

[0055] The vehicle system is used to wake up the detection module control system and the light carpet control system after receiving the unlocking signal.

[0056] Based on the above implementation environment, the embodiment of the present application provides a door control method based on a welcome light carpet. Taking the application of this method to a vehicle control system as an example, the method includes:

[0057] Obtain the door control signal and the ambient brightness signal;

[0058] Determine the types of the door control signal and the ambient brightness signal;

[0059] Determine the door control instruction required for the door control signal type under the ambient brightness signal type;

[0060] Turn on the light carpet projection at the door according to the ambient brightness signal type, and monitor the behavior of the people at the door;

[0061] When it is monitored that the behavior of the people at the door matches the determined door control instruction, control the door according to the door control signal.

[0062] In some embodiments, the types of the door control signal include controlling the door to open for getting on the vehicle and controlling the door to close for getting off the vehicle;

[0063] The types of the ambient brightness signal include day and night.

[0064] In some embodiments, the process of determining the type of the door control signal includes:

[0065] Monitor the vehicle unlocking signal;

[0066] After monitoring the vehicle unlocking signal, monitor the user getting off signal;

[0067] After monitoring the vehicle unlocking signal, if the user getting off signal is monitored within the set time, generate a getting-off door control signal, and determine that the type of this getting-off door control signal is controlling the door to close for getting off the vehicle;

[0068] After monitoring the vehicle unlocking signal, if the user getting off signal is not monitored within the set time, generate a getting-on door control signal, and determine that the type of this getting-on door control signal is controlling the door to open for getting on the vehicle.

[0069] Among them, the vehicle unlocking signal includes but is not limited to the remote key unlocking signal, the UWB unlocking signal, the Bluetooth key unlocking signal, etc.

[0070] The user getting off signal can be characterized by the in-vehicle door opening instruction signal; when the door opening instruction signal is received, it is determined that the user gets off, and the user getting off signal is generated.

[0071] In some embodiments, when the door control signal type is for opening the door for getting in the car and the ambient light intensity signal type is daytime, the required door control instruction is that the user makes a getting-in action in a specific area;

[0072] When the door control signal type is for closing the door for getting out of the car and the ambient light intensity signal type is daytime, the required door control instruction is that the user makes a getting-out action within a specific area;

[0073] When the door control signal type is for opening the door for getting in the car and the ambient light intensity signal type is night, the required door control instruction is that the user makes a getting-in action in a specific area and a movement trend action towards the door;

[0074] When the door control signal type is for closing the door for getting out of the car and the ambient light intensity signal type is night, the required door control instruction is that the user makes a getting-out action within a specific area and a movement trend action away from the door.

[0075] Among them, the recommended range of the specific area is a distance of about 1.5 m from the door, which can allow the user to walk to the front of the car after triggering the door opening, and the door has opened to a suitable position for getting in. Of course, according to the actual situation, it can also be at the 1 m position or the 0.5 m position.

[0076] The getting-in action and the getting-out action can be identified by whether the user kicks a limited area. It is recommended to set the limited area within about half a meter in front of the car door to prevent other pedestrians from accidentally triggering it, and it depends on the specific situation.

[0077] In some embodiments, according to the ambient light intensity signal type, the light carpet projection effect at the door is determined;

[0078] According to the determined light carpet projection effect at the door, the light carpet projection effect at the door is controlled.

[0079] Among them, the light carpet module adopts different projection schemes according to the ambient light intensity signal type, so that the light carpet has different projection effects; specifically, in daytime, the light carpet projection effect is to concentrate the projection brightness of the light carpet in a small area to provide clear and definite instructions for people. This area is recommended to be about 0.01 ㎡, as Figure 5 shown, the shape can be triangular, circular, flower-shaped, special pattern, etc. Different patterns are suitable for different scenarios. Regular patterns such as circles and triangles are suitable for solemn occasions. Flowers imply vitality and give people a sense of prosperity and blooming wealth. Special patterns such as cartoon characters are suitable for children. Of course, this range is not specifically limited. The light carpet projected during the day is to distinguish it from the light carpet projected at night. Hereinafter, it is simply referred to as the light ring. That is, during the day, the light carpet projection effect is the light ring, and at night, a light carpet with a larger projection range is projected to create a welcoming atmosphere and a grand feeling.

[0080] At night, the light carpet projection effect is a light carpet with a certain length and width, which can be clearly visible at night and in low-light environments. There are no restrictions on the shape, length, width, and style, but the length is preferably greater than 2m, and the width is about the same as the door width, which brings a better visual effect to users, showing grandeur and dignity. For example, Figure 6 as shown, different forms are suitable for various occasions. The regular and simple ones are suitable for business occasions, while the ones with rich patterns and vivid colors are suitable for young people pursuing fashion.

[0081] In some embodiments, a specific area can also be combined with the light carpet projection area; for example: when a signal to control the door to open is obtained at night, the light carpet projection is turned on and the projection effect is to project a large-area light carpet. It is necessary to monitor whether the behavior of the person is that the user walks on the large-area light carpet and approaches the door. If so, control the door to open; when a signal to control the door to open is obtained during the day, the light carpet projection is turned on, and the projection effect is a 0.01㎡ aperture. Then it is necessary to monitor whether the behavior of the person is that the user makes a kicking motion within the aperture. If so, control the door to open; the purpose is to prevent users from having a bad user experience due to unclear triggering methods caused by different strategies of the light carpet module.

[0082] In some embodiments, after the light carpet projection at the door is turned on, the position of the user on the light carpet projection area is obtained; according to the position of the user on the light carpet projection area, the light carpet projection effect is dynamically controlled to achieve dynamic changes in the light carpet projection effect. The dynamic changes can be brightness enhancement, color change, or special patterns such as water ripples and lotus blossoms blooming appear in the area of the light carpet stepped on by the person, as Figure 7 shown. Different effects are suitable for different forms of light carpets. At the same time, different effects also bring different experiences to users. For example, the horizontally partitioned light carpet can have dynamic effects such as brightness enhancement and color change in a large area, bringing a sense of grandeur and dignity to users. The simple and broad light carpet can have the effect of lotus blossoms blooming under the feet, giving users a sense of mystery and technology.

[0083] It can also be to control the dynamic change of the light carpet form (brightness, color, etc.) at the position where the person is located (such as brightness enhancement and weakening, color changing from white to yellow, etc.). The range of change depends on the specific light carpet form and the desired change effect. For example, if the light carpet is in the shape of steps, the change effect can be the brightness enhancement and weakening of the light carpet at the level where the user is located, and the color changes from white to yellow. If the light carpet effect is similar to a flat and gentle water surface, the change effect can be water ripples or lotus blossoms blooming at the position where the user steps on, so as to achieve human-computer interaction and welcome effect.

[0084] Detect the behavior of the person at the door through the detection module.

[0085] The detection module can be a radar, an image acquisition device, etc.

[0086] The person at the car door refers to the person within the effective area of the car door; this effective area refers to the area covered by the welcome light carpet.

[0087] In the door control method based on the welcome light carpet provided by the embodiment of the present application, after the overall system receives the vehicle unlocking signal, the detection module control system and the light carpet control system are awakened. At this time, according to the day signal or night signal sent by the light sensor and whether the user getting-off signal is received, the detection module control system and the light carpet control system adopt different strategies;

[0088] The light carpet control system receives the night signal sent by the light sensor. At this time, it controls to project a large-range light carpet. If the light carpet control system receives the day signal sent by the light sensor, then it controls to project an aperture, achieving the effects of being visible during the day and reducing power consumption, and making the functional cost performance higher. When the detection module control system receives the day signal and the user getting-off signal, it controls the detection mode of the detection module to be the daytime getting-off mode, specifically manifested as detecting that the person makes a getting-off action within the aperture, thereby controlling the door to close. When the detection module receives the day signal and does not receive the getting-off signal, it controls the detection mode of the detection module to be the daytime getting-on mode, specifically manifested as detecting that the person makes a getting-on action within the aperture, thereby controlling the door to open. When the detection module control system receives the night signal and the user getting-off signal, the detection mode is the night getting-off mode, specifically manifested as detecting that a person within the large-range light carpet makes a getting-off action and the movement trend of the person moving away from the car door, then controlling the door to close. When the detection module receives the night signal and does not receive the user getting-off signal, the detection mode is the night getting-on mode, specifically manifested as detecting that a person within the large-range light carpet makes a getting-off action and the person gradually moves away from the car door, as well as the movement trend of the person approaching the car door, and controlling the door to open.

[0089] When it is monitored that the behavior of the person at the car door matches the determined control door opening instruction, the door is controlled to gradually open. And when the person walks to the car door, the opening degree of the door reaches the target opening degree, which can be the door being fully opened, so that the person can enter the vehicle smoothly without staying or waiting, improving the person experience and realizing convenient and non-sensing getting on the vehicle.

[0090] In the door control method based on the welcome light carpet provided by the embodiment of the present application, after the vehicle is locked and fortified, the detection module control system and the light carpet control system enter the sleep state. If the vehicle is not locked and fortified in time, then after the preset wake-up time of the detection module and the light carpet, the detection module and the light carpet will automatically go to sleep, thereby reducing power consumption.

[0091] The door control method based on the welcome light carpet provided by the embodiments of the present application uses a detection module to detect the behavior of a person, judge the intention of the person, and combine with AR projection technology (Augmented Reality Projection) to project a welcome light carpet and a cursor, creating a noble atmosphere for the person, providing visual guidance at night, and enhancing the intuitiveness and safety of operations. By combining sensor detection, ambient light signal, and light carpet projection, it can accurately identify the intention of the person all-weather, significantly improving the environmental adaptability and user experience of automatic door opening and closing. Different trigger strategies are adopted during the day and at night to ensure accurate identification of the person's intention to get on or off the vehicle under different lighting conditions and reduce the false trigger rate.

[0092] In the door control method based on the welcome light carpet of the present disclosure, the light carpet control system also dynamically adjusts the light carpet brightness according to the relative position of the person and the light carpet detected by the detection module control system, enabling the person to experience the sense of technology of human-computer interaction. And after the aperture on the light carpet detects an effective action judged by the detection module control system when the person steps on it, corresponding feedback actions will be executed, thus bringing more intuitive and clear feedback information to the person and enhancing the user experience.

[0093] Next, in combination with the process of a person getting on and off the vehicle, the door control method based on the welcome light carpet provided by the embodiments of the present application will be described in detail.

[0094] As Figure 2 shown in S1, when a person gets on the vehicle during the day, the detection module and the light carpet module are awakened and the daytime strategy is executed.

[0095] During the day, when the vehicle system receives an unlocking signal, including a key unlocking signal, a UWB unlocking signal, a mobile phone APP unlocking signal, etc., at this time, the detection module control system and the light carpet control system simultaneously receive the vehicle unlocking signal forwarded by the domain controller, and the detection module and the light carpet are awakened. As Figure 1 shown in 302 and 303, after the detection module control system and the light carpet control system receive the vehicle unlocking signal, they judge whether the ambient light signal sent by the light sensor is daytime. As Figure 1 shown in 304, after the light carpet control system receives the signal sent by the light sensor and judges that it is daytime and the light is sufficient, it controls the light carpet projection effect to be an aperture and enters Figure 1 305. After the detection module control system receives the signal sent by the light sensor, the detection module judges that it is daytime and the detection mode is the daytime mode. Since no user getting-off signal is received within the set time, it is determined that the current scene is a getting-on scene, and the detection module executes the detection strategy when opening the door for getting on, as Figure 1 shown in 306 and 310, and prepares to detect the behavior of the person.

[0096] As Figure 2In S2, if the behavior of the person at the car door matches the car door control instruction required to open the car door during the day, it is determined that the person's behavior is a valid action, the car door is controlled to open, the person gets in the car, and after that, the detection module and the light carpet go into hibernation.

[0097] When a person approaches the car door and triggers a valid action within a specific area, the detection module will detect this valid action in real time and determine whether it is within the range of the valid signal. If a valid signal is detected, the sensor will send the signal to the car door controller. Among them, when the person is within the aperture range projected by the light carpet, it is determined that the action is within the range of the valid signal. After receiving the signal, the car door controller drives the car door motor to perform the door opening action, and the car door opens automatically to facilitate the person to enter the car. This process is Figure 1 as shown in 311 and 312 in

[0098] After the person gets in the car, a door closing signal can be sent through the in-car instruction. After receiving the door closing signal, the car door controller drives the car door motor to perform the door closing action, and the car door closes automatically. After the car door is closed, the vehicle is locked, and the detection module will enter the low-power hibernation state to reduce energy consumption and extend the service life of the device. If the person does not close the door and lock it in time after getting in the car, the system will automatically trigger the hibernation mechanism after the preset time of waking up the detection module ends, making the detection module enter the hibernation state to ensure that the system runs with low power when there is no operation. This module is Figure 4 the hibernation module in Figure 1 as shown in 313 and 314 in

[0099] such as Figure 2 in S3, when the person gets out of the car during the day, the detection module wakes up, and the light carpet module projects an aperture.

[0100] During the day, when the person is about to get out of the car and triggers the user getting out of the car instruction, the sensor controller and the light carpet control system receive the user getting out of the car instruction at the same time and then wake up from the hibernation state. At this time, the light sensor detects that the environmental brightness signal is daytime and sends this signal to the sensor controller and the light carpet control system. The sensor controller switches the working mode to the daytime detection mode according to the daytime signal to support possible subsequent operations of the person; while the light carpet control system projects a smaller range of aperture with concentrated brightness due to the stronger daytime light to ensure that a clear position range display prompt can be provided to the user. The logic of the above process is Figure 1 as shown in 304 and 305 in Figure 1 When the person opens the car door, the sensor controller receives the user getting out of the car instruction and starts to execute the judgment strategy for getting out of the car and closing the door, such as

[0101] such as Figure 2In S4, when a user getting-off instruction is detected and a valid action is triggered by a person in front of the vehicle door, the vehicle door is controlled to close, and after that, the sensor goes to sleep.

[0102] When the detection module senses that a person makes a valid action within the valid area, the vehicle door controller will perform a door-closing operation, and after the vehicle is locked, a signal will be sent to the detection module control system, causing the detection module and the light carpet module to enter the low-power sleep mode, thus effectively saving power consumption. However, if the vehicle door fails to be locked after closing, the detection module and the light carpet module will automatically go to sleep after the preset time elapses, to ensure the low-power state of the system. This design not only avoids unnecessary power consumption caused by the long-term operation of the sensor and the light carpet, but also ensures the real-time monitoring of the vehicle door state and the timely response to personnel operations, achieving a balance between power consumption and function, as Figure 1 shown in 308, 309, and 314 in

[0103] As Figure 3 shown in S1 in

[0104] At night, the vehicle unlocking signal triggers the wake-up mechanisms of the detection module control system and the light carpet control system. These two control systems then receive the night signal from the light sensor, confirming that the current environment is in the night mode. At this time, the light carpet module projects a large-range welcome light carpet, whose shape can be set to a horizontal layered, vertical layered, or a pattern-filled form according to different needs, with a clear brightness, providing a clear visual guide for walking at night. At this time, it is Figure 1 shown as 315 in Figure 1 shown in 316 and 320 in

[0105] When a person steps on the light carpet and walks along its path, the detection module can accurately detect the movement trajectory and distance change of the person. By detecting and transmitting signals in real time, the position of the person on the light carpet can be known. When the person walks to a certain place on the light carpet, the light carpet control system will, according to the position data provided by the detection module, control the form of the light carpet at that position to execute corresponding strategies and dynamically adjust. Of course, it can also control the change of a piece of the light carpet in this range area by analyzing the position data. This form change includes changes in brightness, color, and shape, to provide a more obvious visual guide. This unique design not only enhances the safety of walking at night, but also brings a more intelligent and comfortable experience to the person. This process is Figure 1 shown as 321 in

[0106] AsFigure 3 As shown in S2, when a person triggers a valid action in a specific area of the welcome light carpet and moves towards the car door in line with their movement trend, the car door is controlled to open. The person gets in the car and the light carpet module goes into sleep mode.

[0107] When a person walks along the light carpet and reaches a specific pre-set area on the light carpet, the detection module detects that the user has made a valid action. During this process, the detection module control system detects the movement trajectory and position change of the person, determines that the person has the intention to get in the car, and in combination with the user's valid action, immediately triggers the automatic opening of the car door. When the person reaches the car door, they can get in the car directly without waiting. After getting in the car, the person controls the car door to close and lock inside the car, and the detection module and the light carpet enter the sleep mode. If the person fails to lock the car in time after getting in, the detection module and the light carpet will automatically enter the sleep mode after the preset wake-up time to save energy and ensure the efficient operation of the system, as Figure 1 shown in 322, 323, and 324 in Figure 3.

[0108] As Figure 3 shown in S3, when a person gets out of the car at night, the detection module wakes up and the light carpet module projects the welcome light carpet.

[0109] When a person is about to get out of the car, the vehicle unlock signal is triggered and the car door opens accordingly. At this time, the detection module control system and the light carpet control system both receive the vehicle unlock signal and the user's getting out of the car instruction, then it is determined that the current scenario is the user getting out of the car scenario. In addition, the light sensor detects that the current environment is in the dark state and sends the dark signal to the detection module control system and the light carpet control system. The light carpet control system controls the projection of the welcome light carpet according to the dark signal to provide clear visual guidance for the person. After the light carpet is lit, its shape is similar to a glowing carpet, with a length greater than 2m and a width similar to the width of the car door. The brightness of the light carpet is clearly visible to ensure that the person can walk safely and conveniently when getting out of the car at night. The user walks along the light carpet, and the light carpet can change its shape in real time according to the position of the user to achieve the human-computer interaction experience. As Figure 1 shown in 304 and 315 in Figure 3.

[0110] Since the detection module control system and the light carpet control system have received the user getting out of the car signal, the detection module switches to the getting out of the car detection mode and starts to monitor in real time whether the person makes a valid action in the effective area. As Figure 1 shown in 316 and 317 in Figure 3.

[0111] As Figure 2 shown in S4, when the person moves away from the car door and makes a valid action in a specific area, the car door closes.

[0112] After the person gets out of the vehicle and walks along the guidance of the light carpet, the detection module continuously tracks the movement trajectory of the person. By analyzing the position change of the person, the detection module determines that the person has a tendency to move away from the car door. When the person triggers a valid action in the valid area, combined with the user trend judgment, the detection module determines that the signal is valid and sends a car door closing instruction, and the car door closes automatically.

[0113] After the car door is closed, the person locks the vehicle by remote control or manually. The locking signal triggers the detection module and the light carpet to enter the sleep mode and stop working to save energy consumption. If the person fails to lock the vehicle in time, the system will automatically switch the detection module and the light carpet to the sleep state after the preset time of the wake-up timing of the light carpet and the detection module, ensuring the efficient use of energy and the intelligent management of the system. The above process is Figure 1 as shown in 318, 319 and 324 in

[0121] In some embodiments, the wake-up module is used for the vehicle system to receive the unlock signal to control the wake-up of the detection module control system and the light carpet control system. The light sensor recognizes the night signal to control the light carpet control system to execute corresponding strategies, control the detection module to detect the position of the user on the welcome light carpet in real time, and adopt different welcome light carpet dynamic change strategies according to whether the user getting out of the vehicle instruction is received;

[0122] A control module is used to control the dynamic changes of the welcome mat. The detection module of the control system detects the real-time position of the user on the welcome mat and controls the form of the welcome mat at that position or in a small area, including changes in brightness, color, and shape, to provide a more obvious visual guidance and achieve the effect of human-computer interaction. Moreover, when the detection module detects that the user triggers a valid action, it will transmit a signal to the welcome mat control system to control the welcome mat to execute the corresponding strategy, so that the user can obtain clear feedback information and improve the user experience.
