[0002] As the electrification process of the automotive industry becomes more and more in-depth, electric vehicles are becoming more popular, and the intelligent characteristics of electric vehicles have also been developed to a certain extent. More components for environmental perception have been added to the body of the car; and with the development of mobile Internet, users have higher and higher requirements for the experience of car functions, and the scene-based effects of functions are increasingly valued by the market, so it is expected to better use environmental information to improve the experience of vehicle unlocking functions. Unlocking a vehicle is a basic function of a car and also bears an important responsibility for personal and property safety, and unlocking the car is often a necessary step in using the vehicle. Usually, users will be riding alone or with multiple people. In previous vehicles, users need to find the key in their bag and unlock it by pressing a button, or carry the key to unlock a specific door using keyless entry, but it is often impossible to unlock the door in a targeted manner for scenarios with multiple people riding.

[0003] Currently, vehicles are mainly divided into three categories: those without keyless entry, those with front-door keyless entry, and those with four-door keyless entry. For vehicles without keyless entry, users need to use the key and press buttons within a certain range to open all the doors of the vehicle; for vehicles with front-door keyless entry, since the two front doors of the vehicle are equipped with capacitive sensing devices, when the key is approached, any one of the two front doors can be opened directly or simultaneously, but the rear door is locked; for vehicles with four-door keyless entry, all four door handles are equipped with sensing devices, so when the key is approached, the four doors can be opened at any or all of them.

[0004] The known vehicle unlocking methods have the following disadvantages: users of vehicles without keyless entry need to look for keys when unlocking the car doors; for vehicles that only allow front row unlocking, when there are more than three people in the car, they still need to take out the key to unlock, or unlock the front row first and then unlock the back row, which is not convenient enough; allowing four-door keyless entry, if there is only one person in the car, but there are criminals hiding around the vehicle and entering the car at the unlocking moment, it will bring security problems.

[0020] The following is a description of exemplary embodiments of the present disclosure in conjunction with the accompanying drawings, including various details of the embodiments of the present disclosure to facilitate understanding, which should be considered as merely exemplary. Therefore, it should be recognized by those of ordinary skill in the art that various changes and modifications may be made to the embodiments described herein without departing from the scope and spirit of the present disclosure. Similarly, for the sake of clarity and conciseness, descriptions of well-known functions and structures are omitted in the following description.

[0021] As used herein, the term "including" and its variations mean open inclusion, i.e., "including but not limited to". Unless otherwise stated, the term "or" means "and / or". The term "based on" means "based at least in part on". The terms "an example embodiment" and "an embodiment" mean "at least one example embodiment". The term "another embodiment" means "at least one additional embodiment". The terms "first", "second", etc. may refer to different or the same objects. Other explicit and implicit definitions may also be included below.

[0022] In order to at least partially solve one or more of the above-mentioned problems and other potential problems, an embodiment of the present disclosure proposes a vehicle door unlocking method, including: a first device outputs an identification signal, the identification signal includes location information and verification information; a second device receives the identification signal and determines the location of the first device according to the location information, when the first device is in a preset area, the second device matches and verifies the first device according to the verification information; the second device receives the location information of the first device that is successfully matched, the second device also includes a touch sensor and a pressure sensor, the touch sensor and the pressure sensor are arranged on the vehicle door, the touch sensor outputs a touch signal in response to a touch operation, and the pressure sensor outputs a pressure signal in response to a pressing operation, and the second device unlocks or locks the vehicle door according to the location information, the touch signal and the pressure signal.

[0023] Specifically, in some embodiments, the first device is a door key that integrates a signal transmission module and a remote control module, and the signal transmission module uses radio frequency technology to send an identification signal. The signal transmission module automatically outputs an identification signal in a preset area, so that the user can carry the key close to the vehicle to achieve the key and vehicle matching process, without having to search for the key and then operate the key to match.

[0024] The second device is arranged on the vehicle body, and includes a functional module for receiving and processing radio frequency signals, and is used to perform matching verification on the first device and the second device (or the vehicle) according to the verification information in the identification signal. When the first device fails to match, the second device does not perform the unlocking function judgment.

[0025] When the second device recognizes that the first device is successfully matched, it receives the location information of the first device, and at the same time receives the touch signal and the pressure signal, and unlocks or locks the door according to the touch signal and the pressure signal. The second device outputs an unlock command, and the corresponding door receiving the unlock command can be opened. The second device outputs a lock command, and the door receiving the lock command cannot be opened.

[0026] In some embodiments, the preset area includes a first area and a second area, the distance between the first area and the vehicle body is less than or equal to the first distance, the distance between the second area and the vehicle body is less than or equal to the second distance, and the first distance is greater than the second distance. When the first device is in the first area, the second device matches and verifies the first device according to the identification signal. When the first device is in the second area, the second device starts the unlocking controller, and the unlocking controller unlocks or locks the door according to the position information, touch signal and pressure signal.

[0027] Specifically, the first area is an identification area, and when the first device enters the identification area, the identification signal output by the first device can be received by the second device. The second area is an unlocking area, and when the first device that has successfully matched enters the second area, the unlocking controller is activated. In another embodiment, the second device includes a radio frequency antenna, and when the first device enters the identification area, the radio frequency signal output by the radio frequency antenna is received by the first device, and the first device outputs an identification signal in response to the received radio frequency signal.

[0028] In some embodiments, the first area and the second area are preset areas defined around the vehicle body, for example, the first area and the second area are determined based on the first distance and the second distance, respectively, with each door and the trunk as reference points. Alternatively, in some embodiments, the first area and the second area are determined based on the first distance and the second distance, with the rear fender or the vehicle B-pillar as reference points.

[0029] In some embodiments, when the first device is in the second area, the unlocking controller determines the main control door according to the identification signal, and the main control door is the door closest to the first device.

[0030] Specifically, the unlocking controller determines the nearest door according to the location information of the first device. For example, the door at the main driver's position can be distinguished by the digital door recognition function, so that the driver can control the door unlocking or door locking. Alternatively, when multiple doors include touch sensors and pressure sensors, the unlocking controller controls the door unlocking and door locking according to the touch signals and pressure signals output by the touch sensors and pressure sensors of the main control door.

[0031] In some embodiments, the touch signal includes a first touch signal and a second touch signal, and the pressure sensor includes a pressure threshold, which is greater than 0. By setting the pressure threshold to be greater than 0, input of the pressure signal caused by an erroneous touch can be avoided, thereby improving the judgment accuracy.

[0032] Specifically, Figure 1As shown, the first device enters the first area and sends an identification signal. The second device receives the identification signal and performs matching verification on the first device according to the identification signal. When the first device fails to verify, all doors cannot be unlocked. When the first device succeeds in verification, the corresponding door is unlocked according to the touch signal and the pressure signal according to the preset rule. The first device is connected to the second area, and the second device determines the main control door closest to the first device according to the location information of the first device. When the pressure signal is greater than the pressure threshold, the unlocking controller unlocks all doors in response to the first touch signal, and the unlocking controller locks all doors in response to the second touch signal. When the pressure signal is less than or equal to the pressure threshold, the unlocking controller unlocks the main control door in response to the first touch signal, and the unlocking controller locks all doors in response to the second touch signal. In some embodiments, it also includes a preset time threshold. When the unlocking controller receives the pressure signal for a time interval greater than the preset time threshold and does not receive the touch signal, the unlocking controller unlocks all doors when the pressure signal is greater than the pressure threshold.

[0033] When other conditions are met, if the user only opens the car door, only the door pulled by the user will be unlocked, and the other doors will remain closed, thus achieving the goal of safety; when the user opens the car door after holding it tightly (the pressure signal is greater than the pressure threshold), it means that the user authorizes other doors to be opened, thus achieving convenience.

[0034] In other embodiments, the main control door that is currently closest is determined based on the information of the first position, and the second device unlocks the main control door and locks other doors when it receives a touch signal and a pressure signal at the same time; when the second device does not receive a touch signal but only a pressure signal, it locks all doors.

[0035] On the other hand, a door unlocking system is disclosed, including: a first device, a signal output module of the first device and a remote control module, the signal output module is used to output an identification signal, the identification signal includes a position signal and verification information, and the remote control module is used to lock and unlock the door; a second device, the second device includes a signal receiving module and an identification module, the signal receiving module receives the identification signal, the identification module matches and verifies the first device according to the verification information, the second device also includes a touch sensor, a pressure sensor and an unlocking controller, the touch sensor generates a touch signal in response to a touch operation, the pressure sensor outputs a pressure signal in response to a pressing operation, the unlocking controller receives the matching verification result of the identification module, the second device receives the position information of the first device that matches successfully, and unlocks or locks the door according to the position information, the touch signal and the pressure signal.

[0036] Specifically, Figure 2 and Figure 3 As shown, the signal output module uses radio frequency technology to output identification signals, and the remote control module includes buttons for manually controlling door locking and door unlocking.

[0037] The second device also includes an antenna for outputting a radio frequency signal. When the first device receives the radio frequency signal output by the antenna, it outputs an identification signal. The radio frequency signal output by the antenna can be received by the first device in the first area. The touch sensor and the pressure sensor are arranged on the door handle. The unlocking controller is activated in response to the signal of successful matching. The unlocking controller unlocks or locks the door according to the position signal, the touch signal and the pressure signal of the first device.

[0038] The unlocking controller receives a remote control signal from the remote control module, the remote control signal includes a door unlocking signal and a door locking signal, and the unlocking controller controls the corresponding door to unlock or lock based on the received remote control signal.

[0039] In some embodiments, the touch sensor includes a first sensing area and a second sensing area, the touch sensor outputs a first touch signal in response to a touch operation of the first sensor, and the touch sensor outputs a second touch signal in response to a touch operation of the second sensing area.

[0040] Specifically, the first sensing area is on the inside of the door handle, and the second sensing area is on the outside of the door handle. When the user uses the door handle to pull the door, touching the first sensing area outputs a first touch signal; when the user only touches the second sensing area on the outside of the door handle, a second touch signal is output.

[0041] In some embodiments, the preset area includes a first area and a second area, the distance between the first area and the vehicle body is less than or equal to the first distance, the distance between the second area and the vehicle body is less than or equal to the second distance, and the first distance is greater than the second distance. When the first device is in the first area, the second device matches and verifies the first device according to the identification signal. When the first device is in the second area, the second device starts the unlocking controller, and the unlocking controller unlocks or locks the door according to the position information, touch signal and pressure signal.

[0042] Specifically, the first area and the second area use each door as a reference point, the first distance is greater than the second distance, and the first area includes the second area. That is, when the first device is in the second area, it also belongs to the first area, the first device can also output an identification signal, and the second device performs matching verification on the first device according to the identification signal. In some embodiments, the unlocking controller identifies the current door according to the location information, and obtains the touch signal and pressure signal of the current door to unlock or lock the door.

[0043] In some embodiments, when the first device is in the second area, the unlocking controller determines the main control door according to the identification signal, and the main control door is the door closest to the first device. The pressure sensor includes a pressure threshold, and the pressure threshold is greater than zero. When the pressure signal is greater than the pressure threshold, the unlocking controller unlocks all doors in response to the first touch signal, and the unlocking controller locks all doors in response to the second touch signal. When the pressure signal is less than or equal to the pressure threshold, the unlocking controller unlocks the main control door in response to the first touch signal, and the unlocking controller locks all doors in response to the second touch signal. When the unlocking controller receives the pressure signal for a time interval greater than a preset time threshold and does not receive the touch signal, the unlocking controller unlocks all doors when the pressure signal is greater than the pressure threshold.

[0044] Specifically, when the first device is successfully verified, the unlocking controller responds to the signal of successful matching and starts, and unlocks the door according to the preset rules based on the location information, touch signal and pressure signal of the first device. The first device is connected to the second area, and the second device determines the main control door closest to the first device based on the location information of the first device. When the pressure signal is greater than the pressure threshold, the unlocking controller unlocks all doors in response to the first touch signal, and the unlocking controller locks all doors in response to the second touch signal. When the pressure signal is less than or equal to the pressure threshold, the unlocking controller unlocks the main control door in response to the first touch signal, and the unlocking controller locks all doors in response to the second touch signal. In some embodiments, it also includes a preset time threshold. When the unlocking controller receives the pressure signal for a time interval greater than the preset time threshold and does not receive the touch signal, the unlocking controller unlocks all doors when the pressure signal is greater than the pressure threshold. When the first device fails to be verified, all doors cannot be unlocked.
