Description

Technical Field

[0001] The present disclosure belongs to the field of automobile control technology, and in particular relates to a method and system for opening a front trunk of a vehicle. Background Art

[0002] With the continuous development of automobile technology, people have put forward higher requirements for the convenience and safety of automobiles.

[0003] Existing car trunk opening methods have many inconveniences, such as mechanical pull-cord opening or electric opening, both require opening the main driver's door to open the front trunk switch, which is very inconvenient.

[0004] The existing technology involves two technical means:

[0005] The first method uses facial and voice recognition modules to identify and verify the operator's identity. The detection module generates a trunk lid operation command based on the recognition results. The trunk lid control system then automatically opens the trunk lid upon receiving the command. However, ambient noise can affect the accuracy of voice recognition, resulting in misidentification or even failure to recognize the operator's voice command.

[0006] The second method uses a camera to capture video information, and a motion recognition controller identifies the trajectory of human body movements and determines their validity. Combined with the driver's seat status signal and key signals, it sends an unlock command to the body controller when conditions are met, driving the electric trunk lock to unlock, thus achieving the function of controlling the trunk opening through human body movement. However, if the user is holding large or heavy items, gesture recognition or motion recognition cannot be used, making this opening method unusable.

[0007] In short, the existing technology cannot guarantee the convenience and accuracy of opening the vehicle trunk at the same time. Summary of the Invention

[0008] To solve the above problems, the present invention provides a method and system for opening the front trunk of a vehicle, which uses a car wireless key to communicate with the vehicle key module to wake up the entire vehicle network. When the front high-definition camera detects a person, it collects the face image and uploads it to the information computing center for comparison. After verification, the information computing center sends a signal to the body control module. The body control module executes the opening or non-response of the trunk based on the face recognition result, which can solve the many inconveniences of the trunk opening method in the existing technology.

[0009] When the user walks into the set range around the vehicle with the wireless key, the vehicle's wireless key controller receives the signal sent by the wireless key and wakes up the vehicle network;

[0010] When the vehicle's wireless key controller recognizes that the user walks into the set area in front of the front trunk and stays there for a certain period of time, the vehicle's wireless key controller sends a front trunk unlock request to the body domain controller;

[0011] After receiving the signal, the vehicle body domain controller sends a face recognition request to the front HD camera controller. The HD camera controller controls one or more front HD cameras to capture human portraits. When a human image is captured, face acquisition is performed and timing is started.

[0012] Within a few seconds, one or more front-facing high-definition cameras will upload the captured face to the information computing center for comparison with the facial information stored in the information computing center;

[0013] When the comparison result is passed, the information computing center sends the face recognition result to the body domain controller. When the body domain controller detects that the front trunk is closed, it opens the front trunk.

[0014] Furthermore,

[0015] After the comparison result is passed, if the body domain controller detects that the front trunk is already opened, the body domain controller does not drive the front trunk to unlock.

[0016] Furthermore,

[0017] Also includes:

[0018] Use the on-board sunlight and rain sensor to sense the light intensity around the vehicle;

[0019] When the vehicle's wireless key controller recognizes that the user has walked into the set area in front of the front trunk, the vehicle body domain controller obtains the light intensity information collected by the sunlight and rain sensors;

[0020] If it is determined that the light is insufficient at the time, the body domain controller sends a request to turn on the low beam to the headlight controller. After receiving the request, the headlight controller controls the low beam to be turned on.

[0021] Furthermore,

[0022] When the comparison result is passed, the body domain controller sends a turn signal on signal to the headlight control module. After receiving the signal, the headlight control module lights up the left and right turn signals in front. The turn signals flash multiple times to indicate that the comparison result is passed.

[0023] Furthermore,

[0024] Also includes:

[0025] After the customer manually closes the front trunk, the body domain controller detects that the front trunk is closed and sends a signal to the headlight control module, causing the turn signal to flash multiple times to indicate that the front trunk is successfully closed.

[0026] Furthermore,

[0027] It also includes: when face recognition fails within a certain period of time, or face recognition exceeds a certain number of times, it enters anti-playing mode and stops the front camera face recognition within a certain period of time.

[0028] Furthermore,

[0029] If facial recognition fails within a certain period of time, the body domain controller sends a turn signal turn-on command to the headlight control module. The headlight control module controls the front turn signal to flash five times, prompting the user that the anti-playing mode is about to be entered.

[0030] Furthermore,

[0031] When face recognition exceeds a certain number of times, the body domain controller sends a turn signal turn-on command to the headlight control module. The headlight control module controls the front turn signal to flash five times, prompting the user that the anti-playing mode is about to be entered.

[0032] A vehicle front trunk opening system, characterized by comprising:

[0033] The network wake-up module is used to wake up the vehicle network when the user walks into the set range around the vehicle with the wireless key. The on-board wireless key controller receives the signal sent by the wireless key;

[0035] The face recognition module is used for the vehicle body domain controller to send a face recognition request to the front HD camera controller after receiving the signal. The HD camera controller controls one or more front HD cameras to capture human portraits. When a human image is captured, face acquisition is performed and timing is started.

[0036] Within a few seconds, one or more front-facing high-definition cameras will upload the captured face to the information computing center for comparison with the facial information stored in the information computing center;

[0037] The unlocking module is used to open the front trunk when the information computing center sends the face recognition result to the body domain controller after the comparison result is passed and the body domain controller detects that the front trunk is closed.

[0038] Furthermore,

[0039] Also includes:

[0040] The light sensing module is used to enable the vehicle domain controller to obtain light intensity information collected by the sunlight and rain sensors when the vehicle's wireless key controller recognizes that the user has walked into the set area in front of the front trunk;

[0041] If it is determined that the light is insufficient at the time, the body domain controller sends a request to turn on the low beam to the headlight controller. After receiving the request, the headlight controller controls the low beam to be turned on.

[0042] Compared with the prior art, the present disclosure has the following advantages:

[0043] By using a wireless key controller and a front-mounted high-definition camera for facial recognition, this invention avoids interference from ambient noise in the voice recognition module. This improves recognition accuracy and reliability. Furthermore, the combination of wireless key and facial recognition addresses the issue of users being unable to perform gesture or motion recognition due to holding large or heavy objects. Users simply carry the wireless key within a set range, eliminating the need for gestures.

[0045] In order to more clearly illustrate the embodiments of the present disclosure or the technical solutions in the prior art, the following briefly introduces the drawings required for use in the embodiments or the description of the prior art. Obviously, the drawings described below are some embodiments of the present disclosure. For ordinary technicians in this field, other drawings can be obtained based on these drawings without paying any creative work.

[0046] Figure 1 Shown is a schematic diagram of the method of the present invention;

[0047] Figure 2 Shown is a schematic diagram of the system of the present invention. DETAILED DESCRIPTION

[0048] To make the objectives, technical solutions, and advantages of the embodiments of the present disclosure more clear, the technical solutions in the embodiments of the present disclosure will be clearly and completely described below in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present disclosure, not all of the embodiments. All other embodiments obtained by ordinary technicians in this field based on the embodiments of the present disclosure without making any creative efforts shall fall within the scope of protection of the present disclosure.

[0049] Figure 1 A schematic diagram of the method according to the present invention is shown, and specific implementation details of the present invention include:

[0050] Step 1: When a user walks into a certain area (calibration is required) with a wireless key (but not limited to Bluetooth keys, UWB keys, mobile phone keys, etc.), the wireless key controller receives the signal sent by the wireless key and wakes up the vehicle network.

[0051] Step 2: When the user walks in front of the front trunk, the wireless key controller recognizes that the user is in the openable area of ​​the front trunk (calibration required) and maintains it for a certain period of time (calibration required). The wireless key controller sends a separate unlock request for the front trunk to the body domain controller.

[0052] When the user arrives at the designated area with the wireless key, the body domain controller obtains information from the sunlight and rain sensors. If it determines that the light is insufficient at the time, the body domain controller sends a request to turn on the low beam to the headlight controller. After receiving the request, the headlight controller executes the low beam lighting.

[0053] Step 3: After receiving the signal, the vehicle body domain controller sends a face recognition request to the front HD camera controller. At the same time, one or more front HD cameras capture the portrait. When a human image is captured, face acquisition is performed and timing starts.

[0054] Step 4: Within a few seconds, one or more front-facing high-definition cameras will collect the user's facial information and upload it to the information computing center for comparison with the information stored in the information computing center. When the comparison result is passed, the information computing center sends the facial recognition result to the vehicle body domain controller.

[0055] Step 5: After receiving the signal, the body domain controller detects that the front trunk is closed and opens the front trunk.

[0056] When the face recognition is passed and the body domain controller detects that the front trunk is open, the body domain controller does not drive the front trunk to unlock.

[0057] Specifically:

[0058] After the body domain controller receives the comparison result from the information computing center and detects that the front trunk is closed, it opens the front trunk and sends a turn signal to the headlight control module at the same time. After receiving the signal, the headlight control module lights up the left and right turn signals in front, flashing three times.

[0059] When the customer manually closes the front trunk, the body domain controller detects that the front trunk is closed and sends a signal to the headlight control module to flash the turn signal twice. If the body domain controller detects that the light is dim after the front trunk is closed, the body domain controller sends a signal to the headlight control module to light the headlights and restart the timing.

[0060] When one or more front-facing high-definition cameras fail to compare the user's facial information collected with the internal data of the information computing center, the vehicle body domain controller will not perform unlocking.

[0061] When facial recognition fails within a certain period of time, or facial recognition exceeds a certain number of times, the anti-play strategy is activated, which stops the front camera facial recognition within a certain period of time (calibration is required) to prevent children from playing around and causing energy loss in the vehicle.

[0062] The body domain controller sends a turn signal activation command to the headlight control module, which activates the front turn signal five times, prompting the user to enter anti-play mode for face recognition to open the front trunk. If the light is dim at this time, the module also turns off the low beam headlights. Wait until the next time the wireless key controller receives the proximity signal again.

[0063] The following are the main modules involved in this invention:

[0064] 1. Car wireless key: Connect and communicate with the vehicle key module through a wireless key (but not limited to Bluetooth key, UWB key, mobile phone key, etc.), thereby waking up the vehicle network to enable the body controller and front camera module to work.

[0065] 2. Front-facing HD camera: When one or more front-facing HD cameras detect a person, they capture facial images and upload the collected facial information to the information computing center for facial comparison.

[0066] 3. Information computing center: Identifies and verifies the collected facial images with the information in the database. After verification, it sends the corresponding signal to the body control module.

[0067] 4. Sunlight and rain sensor: Detects whether the current light conditions are sufficient, sends the current light signal to the vehicle body domain controller, and determines whether the front low beam needs to be turned on.

[0068] 5. Body control module: Detects the status of the front trunk and, based on the face recognition results, opens or does not respond to the trunk and sends a signal to the headlight control module.

[0069] 6. Headlight control module: Drives the low beam headlights to light up through the signal fed back by the domain control to provide a certain amount of light for facial recognition, and lights up the front turn signals to prompt the user whether the front trunk is open / closed or in anti-play mode.

[0070] In summary, the solution of the present invention wakes up the entire vehicle network through the communication connection between the car wireless key and the vehicle key module. When the front high-definition camera detects a person, it collects the facial image and uploads it to the information computing center for comparison. After verification, the information computing center sends a signal to the body control module. The body control module executes the opening or non-response of the trunk according to the face recognition result. The sunlight and rain sensor detects the light conditions, and the body control module controls the headlights according to the light conditions to solve the problem that the existing car trunk opening method requires opening the main driver's door, which is inconvenient and increases energy consumption. This method has the advantages of technical safety and reliability, convenience, enhanced interactivity and intelligent experience, energy saving and no additional cost increase.

[0071] The present invention has the following technical advantages:

[0072] 1. The technology is safe and reliable. The front trunk can only be opened after the wireless key is authorized and the face recognition double authentication is passed.

[0073] 2. It provides users with a more convenient user experience. There is no need to open the main driver's door. The front trunk can be opened through wireless key wake-up and face recognition.

[0074] 3. Enhanced interactivity and intelligent experience between users and cars

[0075] 4. Avoids unnecessary energy consumption caused by the change of power mode due to opening the main driver's door, saving energy consumption of the entire vehicle to a certain extent

[0076] 5. There is no additional cost for the whole vehicle. Only software algorithm is needed to realize the use of the front trunk, which makes car maintenance and repair more convenient.

[0077] Based on the method of the present invention, an embodiment of the present disclosure further provides a vehicle front trunk opening system corresponding to the above method, which includes:

[0078] The network wake-up module is used to wake up the vehicle network when the user walks into the set range around the vehicle with the wireless key. The on-board wireless key controller receives the signal sent by the wireless key;

[0079] The detection module is used to send a front trunk unlock request to the body domain controller when the vehicle's wireless key controller recognizes that the user walks into the set area in front of the front trunk and stays there for a certain period of time;

[0080] The face recognition module is used for the vehicle body domain controller to send a face recognition request to the front HD camera controller after receiving the signal. The HD camera controller controls one or more front HD cameras to capture human portraits. When a human image is captured, face acquisition is performed and timing is started.

[0081] Within a few seconds, one or more front-facing high-definition cameras will upload the captured face to the information computing center for comparison with the facial information stored in the information computing center;

[0082] The unlocking module is used to open the front trunk when the information computing center sends the face recognition result to the body domain controller after the comparison result is passed and the body domain controller detects that the front trunk is closed.

[0083] Although the present disclosure has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the aforementioned embodiments, or make equivalent replacements for some of the technical features therein; and these modifications or replacements do not cause the essence of the corresponding technical solutions to deviate from the spirit and scope of the technical solutions of the embodiments of the present disclosure.
