[0043] The specific embodiments of the present disclosure are described in detail below with reference to the accompanying drawings. It should be understood that the specific embodiments described herein are only used to illustrate and explain the present disclosure, and are not used to limit the present disclosure.

[0044] It should be noted that all actions of obtaining signals, information or data in the present disclosure are carried out in accordance with the corresponding data protection regulations and policies of the country where the device is located, and with the authorization given by the owner of the corresponding device.

[0045] As mentioned in the background, both traditional physical keys and digital keys are attached to entities and have the risk of being lost, and the unlocking process is cumbersome. The existing non-inductive unlocking system is composed of a 2D camera, a trigger button / infrared sensor and a separate controller installed in the B-pillar or rearview mirror position of the vehicle, and the unlocking process includes triggering the 2D camera to collect face information by driving the trigger button or through the infrared sensor, and then unlocking the vehicle door according to the face information recognition result.

[0046] However, the trigger button cannot achieve non-inductive door opening, and the unlocking waiting time is too long. The infrared sensor is prone to false wake-up, and the recognition distance of the infrared sensor is short, resulting in the need for the unlocking system to be in a high-power consumption working mode for a long time. The infrared sensor is prone to failure in poor light conditions such as night or rainy and foggy weather, resulting in failure to unlock, and the integration of the entire system is low and the cost is high.

[0047] Therefore, the present disclosure provides a non-inductive door opening system, method and vehicle, which can quickly and non-inductively open the door, does not need to be in a high-power consumption working mode all the time, and reduces the false recognition rate.

[0048] Figure 1 is a block diagram of a non-inductive door opening system according to an exemplary embodiment of the present disclosure. Referring to Figure 1 The system includes a wake-up module 100, an image acquisition module 200 and a central control module 300.

[0049] The wake-up module 100 is configured to wake up the image acquisition module 200 according to the gesture action of the user.

[0050] Specifically, the wake-up module 100 is always in a low-power consumption working state, and in the case that the gesture action of the user is detected and the gesture action meets the wake-up condition, the image acquisition module 200 and the central control module 300 are simultaneously woken up.

[0051] The image acquisition module 200 is configured to acquire face information after being woken up by the wake-up module 100, and send the face information to the central control module 300.

[0052] Specifically, the image acquisition module 200 is always in a low-power state, enters a working state after being woken up by the wake-up module 100, acquires the face information, and sends the face information to the central control module.

[0053] The central control module 300 is configured to generate an unlocking instruction according to the face information to unlock the vehicle door.

[0054] Specifically, referring to Figure 2 The non-sensing door opening system establishes a communication connection with the mobile terminal through the cloud platform, and the user can obtain the unlocking record of the non-sensing door opening system from the cloud platform through the mobile terminal and control the central control module. The wake-up module 100, the image acquisition module 200, and the central control module 300 communicate with each other through an in-vehicle network, which includes CAN, CAN FD, etc. The central control module 300 communicates with the mobile terminal and the cloud platform through an out-of-vehicle network, which includes 4G, 5G, etc.

[0055] The mobile terminal can be a mobile electronic device such as a mobile phone or a tablet.

[0056] For example, referring to Figure 2 The wake-up module 100 wakes up the image acquisition module 200 and the central control module 300 according to the user's gesture action, the image acquisition module 200 acquires the face information and sends it to the central control module 300, the central control module 300 generates an unlocking instruction according to the face information and sends it to the body controller, and the body controller unlocks the vehicle door according to the unlocking instruction.

[0057] The non-sensing door opening system in the present disclosure is always in a low-power state when it is not unlocked, thereby reducing the power consumption of the vehicle and avoiding power feeding of the vehicle. The wake-up module wakes up the image acquisition module according to the user's gesture action, reducing the number of false wake-ups. The image acquisition module acquires the face information after being woken up by the wake-up module and sends the face information to the central control module. The central control module generates an unlocking instruction according to the face information and sends it to the body controller. The unlocking instruction is used to instruct the body controller to unlock the vehicle door, thereby reducing the false recognition rate, avoiding unlocking the vehicle door when the user does not need to open the door, and reducing the false wake-up rate.

[0058] In order to facilitate those skilled in the art to better understand the non-sensing door opening system provided by the present disclosure, the elements in the non-sensing door opening system are described in detail below.

[0059] In a possible embodiment, referring to Figure 3 The wake-up module 100 includes a first millimeter wave radar 101 and a second millimeter wave radar 102, and the frequency band of the first millimeter wave radar 101 is smaller than that of the second millimeter wave radar 102.

[0060] The first millimeter-wave radar 101 is used to wake up the second millimeter-wave radar 102 according to the user's motion status;

[0061] The second millimeter-wave radar 102 is used to wake up the image acquisition module 200 based on the user's gesture.

[0062] The first millimeter-wave radar 101 can be an ultra-low power 5.8GHz millimeter-wave radar, and the second millimeter-wave radar 102 can be a 60GHz millimeter-wave radar.

[0063] In one feasible embodiment, refer to Figure 3 The first millimeter-wave radar 101 is used to acquire the user's motion state within the first detection range, and to wake up the second millimeter-wave radar 102 when the motion state meets the preset motion state. The motion state includes the user's moving speed and moving direction.

[0064] The second millimeter-wave radar 102 is used to acquire the user's dynamic gestures within the second detection range, and to wake up the image acquisition module 200 when the dynamic gestures are consistent with the preset gestures, wherein the second detection range is smaller than the first detection range.

[0065] Wherein, the first detection range is the detection range of the first millimeter-wave radar. In this disclosure, the first detection range is a circular area with a radius of 5m centered on the first millimeter-wave radar. The second detection range is the detection range of the second millimeter-wave radar. In this disclosure, the second detection range is a circular area with a radius of 3m centered on the second millimeter-wave radar.

[0066] Specifically, the preset operating state includes a preset moving speed range and a preset moving direction. In this disclosure, the preset moving speed range is taken as and the preset moving direction is the direction in which the user faces the image acquisition module.

[0067] Specifically, preset gestures can be preset according to the user's wake-up habits. They can be graphics, such as circles, rectangles, triangles, etc., or letters, such as C, V, W, U, etc., or lines, such as waving the palm left and right once, or waving the palm up and down once.

[0068] For example, the 5.8GHz millimeter-wave radar, 60GHz millimeter-wave radar, and image acquisition module are all in a low-power standby state. When the user is less than or equal to 5m away from the 5.8GHz millimeter-wave radar, the user enters the detection range of the 5.8GHz millimeter-wave radar. At this time, the 5.8GHz millimeter-wave radar activates and detects the user's current direction and speed of movement. If the user's current direction of movement is towards the image acquisition module and the speed is within the range of 1m / s to 1.5m / s, the 5.8GHz millimeter-wave radar wakes up the 60GHz millimeter-wave radar. The system then continues to operate within the 60GHz millimeter-wave radar's range. When the distance of the GHz millimeter-wave radar is less than or equal to 3m, the user enters the detection range of the 60GHz millimeter-wave radar. At this time, the 60GHz millimeter-wave radar detects the user's current dynamic gesture. When the dynamic gesture is a C-shape, the 60GHz millimeter-wave radar wakes up the image acquisition module 200, which collects facial information. When the distance between the user and the image acquisition module 200 is less than or equal to 1m, the central control module generates an unlock command based on the facial information and sends it to the body controller. When the distance between the user and the image acquisition module 200 is less than or equal to 0.5m, the body controller completes the unlocking.

[0069] This disclosure employs two millimeter-wave radars of different frequencies to form a gesture recognition wake-up mechanism for millimeter-wave radar. The low-frequency radar has the advantages of long detection range and ultra-low power consumption, while the high-frequency radar has higher detection accuracy and supports gesture recognition, thereby achieving seamless, low-power, and zero-false-trigger fast door opening, avoiding vehicle power depletion and reducing false wake-up rate.

[0070] In one feasible embodiment, refer to Figure 3 The wake-up module 100 also includes a micro switch 104 or a touch switch 103;

[0071] The micro switch 104 is used to wake up the image acquisition module 200 when a user's pressing operation is detected;

[0072] The touch switch 103 is used to wake up the image acquisition module 200 when the user's touch operation is detected.

[0073] This invention enables the image acquisition module to be activated by pressing a microswitch or touching a touch switch when the millimeter-wave radar malfunctions, thus ensuring the reliability of the contactless door opening system.

[0074] In one feasible embodiment, the central control module 300 is used to match facial information with pre-stored facial information. If the match is successful, an unlocking command is generated and sent to the body controller to instruct the body controller to unlock the vehicle door.

[0075] Specifically, the pre-stored face information can include face information of the car owner, face information of family members of the car owner, and face information of friends of the car owner, wherein, the reference Figure 2 The user can pre-store the face information through the mobile terminal.

[0076] Specifically, the central control module 300 is integrated with a face recognition algorithm, and the face recognition algorithm of the central control module 300 compares the face information with the pre-stored face information. In the case of consistent comparison results, a unlocking instruction is generated, and in the case of inconsistent comparison results, the indicator light is controlled to display red to remind the user of unlocking failure.

[0077] In a feasible embodiment, the image acquisition module 200 includes a 3D depth camera.

[0078] Specifically, the 3D depth camera acquires a gray image and a depth image of the face as the face information, and the gray image and the depth image can be live body recognition, which improves the security of face recognition, and the 3D depth camera can work under 940nm wavelength, which is not affected by the working condition, and can acquire the face information in time.

[0079] Specifically, the 3D depth camera in the present disclosure is a 3D TOT (Time Of Flight) camera.

[0080] In a feasible embodiment, the reference Figure 3 The system further includes an indicator light 400, which is used to perform at least one of the following display operations:

[0081] According to the running state of the wake-up module 100, a light of a first preset color is displayed;

[0082] According to the running state of the image acquisition module 200, a light of a second preset color is displayed;

[0083] According to the running state of the central control module 300, a light of a third preset color is displayed;

[0084] The first preset color, the second preset color, and the third preset color are different.

[0085] Specifically, the first preset color, the second preset color, and the third preset color can be preset according to the user's usage habits. The present disclosure takes the first preset color as green or blue, the second preset color as orange, and the third preset color as yellow.

[0086] For example, the reference Figure 3The indicator light 400 is used to display green or blue light according to the running state of the wake-up module 100; the indicator light 400 is used to display orange light according to the running state of the image acquisition module 200; and the indicator light 400 is used to display yellow light according to the running state of the central control module 300.

[0087] In a feasible embodiment, referring to Figure 3 The system further comprises a light supplementing module 500, which is used to provide a light source when the image acquisition module 200 acquires the face information.

[0088] The present disclosure provides a light source by the light supplementing module 500 when the image acquisition module 200 acquires the face information, avoids the failure to acquire the face information in the case of poor light such as night or rainy and foggy weather, and improves the reliability of the non-sensing door opening system.

[0089] For example, referring to Figure 4 In step S11, the first millimeter wave radar acquires the running state of the user in the first detection area, and wakes up the second millimeter wave radar in the case that the motion state meets the preset running state, and at this time the indicator light displays green light.

[0090] In step S12, the second millimeter wave radar acquires the dynamic gesture of the user in the second detection area, and wakes up the 3D depth camera in the case that the dynamic gesture is consistent with the preset gesture, and at this time the indicator light displays blue light.

[0091] In step S13, the 3D depth camera acquires the face information after being woken up while the light supplementing module provides a light source, and the 3D depth camera sends the face information to the central control module, and at this time the indicator light displays orange light.

[0092] In step S14, the central control module generates an unlocking instruction according to the face information, and sends the unlocking instruction to the vehicle body controller, and at this time the indicator light displays yellow light.
