[0002] With the development of social economy, cars have become daily consumer goods and have begun to enter more and more ordinary people's homes. With the increase in car sales, people's requirements for the use of car functions have also increased. Therefore, car developers have developed remote control car keys to replace traditional mechanical car keys to provide maximum convenience and safety for car owners. At present, car owners can press the unlock button on the smart key to send an unlock signal to the car through the smart key. After the car receives the unlock signal, it can unlock the car door. However, this door unlocking method requires the owner to carry the smart key to unlock the vehicle. Once the owner does not bring the smart key or the smart key is out of power, the vehicle will not be able to unlock. In some uninhabited or remote mountainous areas, there are often imperfect infrastructure, poor network signals or weak networks. In this environment, the owner's use of mobile phone APP to unlock is often ineffective, and can only be unlocked by car keys or physical keys, resulting in a poor user experience.

[0041] To make the purpose, technical scheme and advantages of the embodiments of the present application clearer, the technical scheme in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are only a part of the embodiments of the present application, rather than all of the embodiments. The components of the embodiments of the present application usually described and shown in the drawings here can be arranged and designed in various different configurations. Therefore, the following detailed description of the embodiments of the present application provided in the drawings is not intended to limit the scope of the application claimed for protection, but merely represents the selected embodiments of the present application. Based on the embodiments of the present application, each other embodiment obtained by those skilled in the art without making creative work belongs to the scope of protection of the present application.

[0042] First, the application scenarios to which the present application is applicable are introduced. The present application can be applied in the field of vehicle unlocking technology.

[0043] According to research, with the development of social economy, cars have become daily consumer goods and have begun to enter more and more ordinary people's homes. With the increase in car sales, people's requirements for the use of car functions have also increased. Therefore, car developers have developed remote control car keys to replace traditional mechanical car keys to provide maximum convenience and safety for car owners. At present, car owners can press the unlock button on the smart key to send an unlock signal to the car through the smart key. After the car receives the unlock signal, it can unlock the car door. However, this door unlocking method requires the owner to carry the smart key to unlock the vehicle. Once the owner does not bring the smart key or the smart key is out of power, the vehicle will not be able to unlock. In some uninhabited or remote mountainous areas, there are often imperfect infrastructure, poor network signals or weak networks. In this environment, the owner's use of mobile phone APP to unlock is often ineffective, and can only be unlocked by car keys or physical keys, resulting in a poor user experience.

[0044] Based on this, an embodiment of the present application provides a vehicle unlocking method, which realizes a method for unlocking a vehicle by using a regularly flashing light signal in the case of a weak network, no network, and a mobile phone without power, making it convenient for users to unlock the vehicle.

[0045] See also Figure 1 , Figure 1 This is a flow chart of a vehicle unlocking method provided by an embodiment of the present application. Figure 1 As shown in , the vehicle unlocking method provided by the embodiment of the present application includes:

[0046] S101: collecting optical signal information for vehicle unlocking sent by a user terminal in real time, performing signal conversion processing on multiple optical signals in the optical signal information, and determining a voltage signal corresponding to each optical signal.

[0047] In this step, the light sensing device collects in real time a regularly flashing light signal information sent by the user end for unlocking the vehicle, performs signal conversion processing on each light signal in the light signal information, and determines the voltage signal corresponding to each light signal.

[0048] Among them, the light sensing device is arranged on the roof of the vehicle, and in the present application, the light sensing device can be replaced by a light sensor.

[0049] Here, when the light sensing device collects a period of regularly flashing light signal information, it converts the light signal to obtain a voltage signal corresponding to each light signal.

[0050] Among them, light sensing devices include solar panels, light sensors and other devices that can receive and process light signals.

[0051] Among them, a regularly flashing light signal can be generated by the user end based on the mobile phone flash, flashlight or sunshade.

[0052] S102: Determine whether the user end has successfully shaken hands with the light sensing device based on a voltage signal corresponding to the light signal before a preset number of light signals among a plurality of light signals.

[0053] In this step, whether the user end has successfully shaken hands with the light sensing device is determined based on a voltage signal corresponding to a preset number of light signals before a period of regularly flashing light signal information.

[0054] Here, the preset number can be 4, and this part is not specifically limited.

[0055] In a possible implementation manner, determining whether the user end has successfully handshaked with the light sensing device based on a voltage signal corresponding to a preset number of light signals among the multiple light signals includes:

[0056] A: Detect whether the first voltage signal corresponding to the first light signal exceeds a preset voltage signal.

[0057] Here, it is detected whether the first voltage signal corresponding to the first light signal exceeds the preset voltage signal.

[0058] B: If yes, determine the first holding time corresponding to the first optical signal, and detect whether the voltage difference between the second voltage signal and the first voltage signal is greater than a preset threshold.

[0059] Here, if yes, then the first holding time corresponding to the first optical signal is determined, and it is detected whether the voltage difference between the second voltage signal and the first voltage signal is greater than a preset threshold.

[0060] C: If it is greater than the preset threshold, continue to judge whether the voltage difference between the current voltage signal and the previous voltage signal is greater than the preset threshold until a preset number of optical signals pass the detection, and determine that the handshake is successful.

[0061] Here, if it is greater than the preset threshold, the voltage difference between the current voltage signal and the previous voltage signal is further determined to be greater than the preset threshold until a preset number of optical signals pass the detection, and then the handshake is determined to be successful. If any optical signal fails to pass, the handshake is unsuccessful.

[0062] In the present application, the comparator in the light sensing device compares the current voltage with the voltage output at the previous moment, and the MCU parses the signal according to the protocol and determines whether to output to the CAN line unlocking or warning.

[0063] In a specific embodiment, the duration of the optical signal exceeding the threshold is T1-T4. The size of T1-T4 also has a predetermined range, which is calculated based on the owner's habits and when setting the key. The handshake process using T1-T4 can ensure that the time is flexible and not affected by the performance of the mobile phone.

[0064] S103: If the handshake is successful, determining whether the plurality of optical signals are the optical key of the vehicle based on the voltage signal after the preset number and the standard upper and lower edge trigger signals corresponding to the pre-stored optical key of the vehicle.

[0065] In this step, if the handshake is successful, it is determined whether the multiple optical signals are the optical key of the vehicle based on the voltage signal after the preset number and the standard upper and lower edge trigger signals corresponding to the pre-stored optical key.

[0066] Here, the pre-stored optical key is that the user end (APP end) sends a password registration and login request to the cloud platform. After receiving the password registration and login request, the cloud platform sends an ACK authentication request to the user end. After receiving the ACK authentication request, the user end sends a certificate authentication to the cloud platform. After the cloud platform successfully authenticates the certificate, it notifies the user end that the optical key can be set, receives a regularly flashing light signal set by the user end as the optical key, and sends the optical key to the vehicle's TBOX. The TBOX then sends the optical key to the light sensing device for storage to obtain the pre-stored optical key.

[0067] The corresponding standard rising and falling edge trigger signals are preset by the user using the user terminal (APP).

[0068] The voltage signal after the preset number is a voltage signal after a preset number of voltage signals.

[0069] In a possible implementation manner, determining whether the plurality of optical signals are the optical keys of the vehicle based on the voltage signals after the preset number and the standard up and down edge trigger signals corresponding to the optical keys includes:

[0070] a: Determine the starting position of the password transmission end corresponding to the remaining optical signals, and determine multiple valid voltage signals between the starting position of the password transmission end and multiple optical signals after the starting position.

[0071] Here, the starting position of the password transmission end corresponding to the remaining optical signal is determined, and multiple valid voltage signals between the starting position of the password transmission end and multiple optical signals after the starting position are determined.

[0072] The voltage signal corresponding to the light signal between the starting position where the password transmission corresponding to the remaining light signal ends and the preset number of light signals after the starting position is taken as the effective voltage signal. For example, if the starting position is the 5th light signal and the preset number is 7 light signals, the voltage signals corresponding to the 5th light signal and the 11th light signal are taken as the effective voltage signal.

[0073] The effective voltage signal is an optical password signal input by the user.

[0074] In a possible implementation manner, the starting position where the password transmission corresponding to the remaining optical signal ends is determined by the following steps:

[0075] A plurality of continuous optical signals with an average maintenance time are detected in the regularly flashing optical signal; and the signal start positions of the plurality of continuous optical signals with an average maintenance time are used as the start positions of the end of password transmission.

[0076] Here, a plurality of continuous optical signals with an average maintenance time are detected in a regularly flashing optical signal, and the signal start positions of the plurality of continuous optical signals with the average maintenance time are taken as the start positions of the end of the password transmission.

[0077] The average holding time is an average value of multiple holding times in the handshake phase.

[0078] b: Perform binary data conversion processing on the multiple effective voltage signals, and convert the effective voltage signals after the binary data conversion processing into upper and lower edge trigger signals according to Manchester encoding.

[0079] Here, binary data conversion processing is performed on a plurality of effective voltage signals, and the effective voltage signals after the binary data conversion processing are converted into up-and-down edge trigger signals according to Manchester encoding.

[0080] In a possible implementation manner, performing binary data conversion processing on the plurality of effective voltage signals, and converting the effective voltage signals after the binary data conversion processing into upper and lower edge trigger signals according to Manchester encoding, includes:

[0081] (1): Based on the rising edge trigger signal corresponding to the effective voltage signal under two average maintenance times and the falling edge trigger signal corresponding to the effective voltage signal under one average maintenance time, a 1 in binary is constructed.

[0082] Here, the rising edge trigger signal corresponding to the effective voltage signal under two average maintenance times and the falling edge trigger signal corresponding to the effective voltage signal under one average maintenance time constitute 1 in binary.

[0083] (2): Based on the rising edge trigger signal corresponding to the effective voltage signal under one average maintenance time and the falling edge trigger signal corresponding to the effective voltage signal under two average maintenance times, 0 in binary is constructed.

[0084] Here, a rising edge trigger signal corresponding to an effective voltage signal under an average maintenance time and a falling edge trigger signal corresponding to an effective voltage signal under two average maintenance times constitute 1 in binary.

[0085] For further information, see Figure 2 , Figure 2 Schematic diagram of the upper and lower edge trigger signals corresponding to the optical signals provided in the embodiment of the present application. Figure 2 As shown, T1 / T2 / T3 / T4 are used as the optical signal in the handshake stage, and the average maintenance time T5 is calculated according to the maintenance time corresponding to T1 / T2 / T3 / T4. After T4 is the data domain, T11 is twice T5, T12 is equal to T5 with an allowable error of 30%, T11 and T12 are combined to be 1, T13 is equal to T5, and T14 is combined to be twice T5 with an allowable error of 30%. T13 and T14 are combined to be 0, and when the transmission is ended, 10 T5s are maintained.

[0086] In this application, T1-T4 is a handshake area, which serves as a basic unit time. A high voltage and a low voltage combination in the data area generates a BIT data. Figure 2 The combination of T11 and T12 produces 1BIT data, which can effectively filter natural light and ensure that no errors are generated. Setting the handshake area can effectively overcome the problem of being unable to unlock caused by equipment performance and equipment errors.

[0087] In a possible implementation manner, the average maintenance time is determined in the following manner:

[0088] The maintenance time corresponding to the light signals before a preset number is averaged to determine the average maintenance time.

[0089] c: Compare the falling edge trigger signal corresponding to the effective voltage signal with the standard rising and falling edge trigger signals corresponding to the pre-stored optical key. If the comparison is successful, the multiple optical signals are the optical keys of the vehicle; if the comparison fails, the multiple optical signals are not the optical keys of the vehicle.

[0090] Here, the falling edge trigger signal corresponding to the effective voltage signal is compared with the standard rising and falling edge trigger signals corresponding to the pre-stored optical key. If the comparison is successful, the multiple optical signals are the optical key of the vehicle; if the comparison fails, the multiple optical signals are not the optical key of the vehicle.

[0091] S104: If yes, unlocking the vehicle based on the regularly flashing light signal.

[0092] In this step, if yes, the vehicle is unlocked according to a regularly flashing light signal.

[0093] In a possible implementation manner, after determining whether the regularly flashing light signal is the optical key of the vehicle based on the remaining voltage signals after the preset number of voltage signals and the standard upper and lower edge trigger signals corresponding to the optical key, the vehicle unlocking method further includes:

[0094] If not, the vehicle alarm is triggered and a warning notification is sent to the user.

[0095] In a specific embodiment, the user end (APP end) sends a password registration and login request to the cloud platform. After receiving the password registration and login request, the cloud platform sends an ACK authentication request to the user end. After receiving the ACK authentication request, the user end sends a certificate authentication to the cloud platform. After the cloud platform successfully authenticates the certificate, it notifies the user end, receives the optical key set by the user end, and sends the optical key to the vehicle's TBOX. TBOX then sends the optical key to the optical sensing device. When the user clicks the optical unlocking command on the user end, a regularly flashing light signal is sent. After receiving a regularly flashing light signal, the optical sensing device processes the light signal to determine whether the light signal is an optical key. If so, TBOX is notified to unlock the vehicle. If not, the vehicle is alarmed.

[0096] The embodiment of the present application provides a vehicle unlocking method, which is applied to a photosensitive device, and includes: real-time collection of a regularly flashing light signal sent by a user end for vehicle unlocking, signal conversion processing of the regularly flashing light signal, and determination of the voltage signal corresponding to each light signal; based on the voltage signal corresponding to the light signal before a preset number of the regularly flashing light signals, determining whether the user end has successfully shaken hands with the photosensitive device; if the handshake is successful, determining whether the regularly flashing light signal is the vehicle's optical key based on the remaining voltage signals after the preset number of voltage signals and the standard upper and lower edge trigger signals corresponding to the optical key; if so, unlocking the vehicle based on the regularly flashing light signal. A method for unlocking a vehicle using a regularly flashing light signal is realized in the case of a weak network, no network, and a dead mobile phone, making it convenient for users to unlock the vehicle.

[0101] Further, when the handshake detection module is used to determine whether the user end has successfully shaken hands with the light sensing device based on the voltage signal corresponding to the light signal before the preset number of light signals among the multiple light signals, the handshake detection module is specifically used to:

[0102] Detecting whether the first voltage signal corresponding to the first optical signal exceeds a preset voltage signal;

[0112] Based on the rising edge trigger signal corresponding to the effective voltage signal under one average maintenance time and the falling edge trigger signal corresponding to the effective voltage signal under two average maintenance times, 0 in binary is constructed.

[0113] Furthermore, the key comparison module determines the average maintenance time in the following manner:
