Description

TECHNICAL FIELD

[0001] The utility model relates to a vehicle door unlocking technical field, especially a vehicle door automatic unlocking device based on big data and artificial intelligence. BACKGROUND

[0002] The popularity of electric new energy vehicles reduces travel and maintenance costs and is more green and environmental protection, but the commonly used power battery at present is mainly liquid lithium battery, and the situation of fierce combustion in a short time after the accident occurs frequently. The vehicle accident, especially the serious accident, usually causes the vehicle personnel to be in a state of loss of consciousness, and it is difficult to unlock the vehicle door from the vehicle. The vehicle outside personnel is difficult to quickly open the vehicle door in the vehicle door unlocking state, so it is particularly important to automatically unlock the vehicle door at the first time after the vehicle accident to rescue the vehicle personnel.

[0003] In a new energy vehicle accident, if the left upper side of the vehicle is hit, the front engine compartment and the passenger compartment are easily damaged, the communication wire harness is instantaneously cut off, the door handle controller cannot receive the pop-up signal, the front engine compartment is ignited by the high-temperature component or the wire harness short-circuit spark, the left side of the front engine compartment is first on fire, and the fire spreads to the whole vehicle. At the same time, the performance of the vehicle door unlocking device in other accidents can be summarized as the deficiencies in the prior art, that is, (1) non-integrated, relying on external power supply, external control signal or external sensor to provide information, when the power supply, power supply or communication line is damaged due to the accident, the unlocking device is invalid; (2) the structure of the unlocking device is not solid enough, and the unlocking device is damaged and invalid due to the accident; (3) the accuracy of judging the vehicle accident state needs to be further improved, and some special accidents such as special collision direction cannot be accurately judged.

[0004] Therefore, in order to ensure that the function of the vehicle door automatic unlocking device can be reliably executed, the device should have three basic requirements: (1) integrated, that is, cannot rely on external power supply, external sensor and external control signal which need long line connection, so as to prevent the vehicle door automatic unlocking function from being invalid due to the damage of external power supply, power supply line, sensor and control line caused by the accident; (2) the vehicle door automatic unlocking device itself has a solid, waterproof and fireproof shell and internal mechanical structure; (3) has the ability to accurately judge the vehicle accident state. Some existing products do not have independent power supply, so they cannot work normally when the vehicle main power supply or power supply line is damaged. Some products rely on the airbag trigger signal of the vehicle itself to judge whether an accident occurs, but some serious accidents do not produce airbag opening signals due to collision direction and other reasons, so the vehicle door automatic unlocking cannot be triggered. Some products rely on the vehicle's own acceleration sensor to collect vehicle speed information, which will also cause the vehicle door unlocking device to fail when the communication line is damaged in the accident, thus losing the best opportunity for rescue.

[0005] Therefore, there is an urgent need for a new completely independent full integration, solid, can accurately identify the vehicle accident state of the vehicle accident after the automatic unlocking device of the vehicle door. The utility model discloses

[0007] In order to solve the deficiencies in the prior art, namely (1) non-full integration, must rely on external power supply, external control signal or external sensor to provide information, when the accident causes the power supply, power supply or communication line damage, the unlocking device is invalid;(2) the structure of unlocking device is not solid enough, and the unlocking device is damaged and invalid due to accident;(3) the accuracy of identifying the vehicle accident state needs to be further improved, and some special accidents such as special collision direction still cannot be accurately identified, the utility model provides an automatic unlocking device of vehicle door after accident based on big data and artificial intelligence, has the following advantages: (1) independent full integration, that is, all components are integrated in the shell of the device, does not rely on external power supply, does not rely on external control signal or external sensor information, reduces the failure probability of the device after the accident;(2) the structure is solid, has a solid protective shell and is firmly fixed in the door, and the device can be effectively protected from damage in the accident;(3) the size and direction of vehicle acceleration are compared with the vehicle accident state model generated based on big data and artificial intelligence, and the accuracy of identifying the vehicle accident state is further improved. When detecting that the vehicle is in accident state, the device waits n (for example n=10) after unlocking the door and sending accident alarm information, sends sound and light alarm signal, and creates favorable conditions for the valuable time of the rescue of the personnel in the accident vehicle.

[0035] The unlocking device 4 is a motor-driven vehicle door opening and closing unlocking device, which performs the vehicle door unlocking operation under the control of the main control device 1. Exemplarily, the unlocking device 4 is an L99DZ100 purchased from STMicroelectronics.

[0036] The positioning device 5 is a Beidou or GPS geographic position positioning module, which is connected with the main control device 1 through a signal line and provides the main control device 1 with geographic position information; the Beidou or GPS geographic position positioning module is an AT6558R Beidou GPS dual-mode positioning radio frequency baseband chip purchased from the market.

[0037] The distress signal sending device 6 is a WIFI or wireless mobile terminal or a combination thereof, which is connected with the main control device 1 through a signal line, and its function is to send the distress information of the vehicle accident and the geographic position of the accident to the terminal set in advance under the control of the main control device 1 when the main control device 1 receives the notification of the accident state; exemplarily, the WIFI terminal is an AIC8800DL of Aikemi.

[0038] The sound and light warning device 7 is a loudspeaker capable of emitting an alarm sound and a light-emitting unit capable of emitting an alarm light signal, which is connected with the main control device 1 through a signal line, and its function is to remind the surrounding people that there is a danger after the device judges that the vehicle has an accident, so as to avoid or obtain the help of others; the model of the sound and light warning device 2 is AN-119 or BT-107.

[0039] The battery and charging device 8 is connected with the master control device 1 through signal line and power line, and is controlled by the master control device 1, and at the same time, provides power supply for the master control device 1. The battery and charging device 8 is connected with the acceleration sensor 2, the data processing and accident state distinguishing device 3, the unlocking device 4, the positioning device 5, the help signal sending device 6, the sound and light warning device 7, and the external power supply detecting device 9 through power line and provides power supply for them. The battery and charging device 8 charges the battery under the control of the master control device.

[0040] The external power supply detecting device 9 monitors the voltage value of the vehicle main power supply in real time in the vehicle starting state, and compares the voltage value with the normal voltage value. If the voltage value of the vehicle main power supply suddenly decreases by a certain percentage, such as 50%, from the normal value in a short time, such as 5 seconds, it is determined that the vehicle main power supply is damaged due to an accident, and the vehicle is in an accident state, and the determination result is immediately sent to the master control device 1. The external power supply detecting device 9 is a MAX4080 power supply detecting module purchased externally.

[0041] The protective shell 10 protects the internal components of the rescue device and provides mounting and fixing holes of the device and the vehicle door frame.

[0042] The state of the rescue device provided by the utility model can be divided into two states of shutdown state and working state.

[0043] The working process of the rescue device will be described in detail below according to different states.

[0044] When the rescue device provided by the utility model is in the shutdown state:

[0045] When the vehicle is normally turned off or the main power supply is normally turned off, the device enters the shutdown state.

[0046] In the shutdown state, all components in the device stop working and stop consuming current.

[0047] When the vehicle is normally started or the main power supply is turned on, the device enters the working state.

[0048] In the working state, the main control device 1 controls the rest of the components to enter the working state. The main control device 1 determines that the vehicle is in the accident state in two cases: (1) receiving the vehicle accident state information from the data processing and accident state determination device 3; (2) the external power supply detection device 9 monitors the voltage value of the vehicle main power supply in real time in the vehicle starting state and compares it with the normal voltage value. If the voltage value of the vehicle main power supply suddenly drops from the normal value to a certain percentage, such as 50%, within a short period of time, such as 5 seconds, it is determined that the vehicle main power supply is damaged due to an accident, and it is determined that the vehicle is in an accident state. When the main control device 1 determines that the vehicle is in the accident state, it waits for n seconds (for example, n = 10) before unlocking the door and sending a distress signal, and issuing an audible and light alarm signal to save valuable time and create favorable conditions for rescuing the people in the accident vehicle. The reason why the main control device 1 determines that the vehicle is in the accident state and waits for n seconds before unlocking the door is to prevent the vehicle from rolling after the accident. At this time, unlocking the door may cause the person inside the vehicle who is not wearing a seat belt to fall out of the vehicle and cause more harm. Waiting for n seconds before unlocking the door when the vehicle is in a stationary state is relatively safer. Using a waiting time of n seconds instead of using the data analysis results of the acceleration sensor 2 to determine whether the vehicle has entered a stationary state after the accident is because the waiting time of n seconds can be completed using a simple counter, and its reliability after the accident is much higher than using the data from the acceleration sensor 2 to determine whether the vehicle is in a stationary state.

[0049] In the working state, the acceleration sensor 2 collects the direction and size information of the acceleration in real time under the control of the main control device 1, and transmits the information to the data processing and accident state determination device 3;

[0050] In the working state, the data processing and accident state determination device 3 processes the direction and size information of the acceleration and compares it with the model in the accident state database. When it is determined that the vehicle is in an accident state, the determination result is immediately sent to the main control device 1;

[0051] In the working state, the unlocking device 4 performs the unlocking operation under the control of the main control device 1;

[0052] In the working state, the positioning device 5 transmits the collected geographic location information to the main control device 1 in real time;

[0053] In the working state, the distress signal sending device 6 can send a distress signal and geographic location information to the previously agreed information receiving party under the control of the main control device 1;

[0054] In the working state, the audible and light alarm device 7 issues an audible and light alarm after the accident under the control of the main control device 1;

[0055] In the working state, the battery and charging device 8 supplies power to the rest of the components in the device and charges the battery under the control of the main control device 1;

[0056] In the working state, the external power supply detection device 9 monitors the voltage value of the vehicle main power supply in real time under the control of the master control device 1 and compares it with the normal voltage value, and if the voltage value of the vehicle main power supply suddenly decreases from the normal value to a certain percentage, such as 50%, within a short time, such as 5 seconds, it is determined that the vehicle main power supply is damaged due to an accident and the vehicle is in an accident state.

[0057] The comparison threshold stored in the threshold memory U6 is a vehicle accident judgment threshold determined by a large amount of vehicle acceleration information data and artificial intelligence software when the vehicle is normally running and when an accident occurs, which is written into the threshold memory U6 before the product is shipped, and the threshold memory U6 only serves to store the threshold and output it to the input end of the XNOR gate. Artificial intelligence software includes but is not limited to Wenxin Yiyang, Qianyitong, etc. This application does not involve the improvement of artificial intelligence software, only the comparison result (digital signal, etc.) of the data processing and accident state discrimination device is input into the existing artificial intelligence software to obtain the vehicle accident comparison judgment threshold recommended by the artificial intelligence.

[0058] In the utility model, the control information between the master control device and other modules is realized through the pins of the master control device chip, that is, the master control device is connected with other modules through the pins set in advance, and the control signal is high and low level, such as high level, and the acceleration sensor 2 is started, and the acceleration sensor 2 stops working when the low level. The corresponding control method is the prior art in the art, only the corresponding setting according to the instruction manual of the master control device is needed, and the utility model does not need to be repeated. Exemplarily, the single-chip microcomputer model of the master control device is AT89C51.

[0059] The utility model embodiment has at least the following beneficial effects:

[0060] (1) independent full integration, that is, all components are integrated in the device shell, which does not depend on external power supply, external control signal or external sensor information, and reduces the failure probability of the device after the accident;

[0061] (2) The structure is firm, has a firm protective shell and is firmly fixed in the door, and can effectively protect the device from damage in the accident;

[0062] (3) The vehicle acceleration size and direction are compared with the vehicle accident state threshold generated based on big data and artificial intelligence, which further improves the accuracy of judging the vehicle accident state.
