Detailed Description

In the related technology, the digital car key represents virtual digital backup information of an entity car key, and by using the digital car key technology, an effective basis for mutual authentication between a car and a legal user can be realized based on an asymmetric key signature and signature verification mechanism.

According to different Communication modes of vehicles and keys, the Communication modes of digital vehicle keys in the related art mainly include bluetooth, mobile network and Near Field Communication (NFC). Due to the existence of network-free environments such as underground garages, bluetooth and NFC are communication modes widely adopted by digital car keys.

NFC is a new technology, and devices using NFC technology can exchange data when they are close to each other, and is integrated and evolved from non-contact Radio Frequency IDentification (RFID) and interconnection technology, and by integrating functions of an induction card reader, an induction card, and point-to-point communication on a single chip, mobile payment, electronic ticketing, door access, mobile identity recognition, anti-counterfeiting, and the like using a mobile terminal

Bluetooth is a short-distance wireless communication technology, and can realize data exchange between fixed equipment and a mobile terminal. Bluetooth prior to bluetooth 3.0 using bluetooth Basic Rate (BR) or Enhanced Data Rate (EDR) technology is generally referred to as legacy bluetooth, while bluetooth under the bluetooth 4.0 specification is referred to as Bluetooth Low Energy (BLE). The bluetooth 4.0 standard includes a conventional bluetooth module portion and a bluetooth low energy module portion. The bluetooth low energy is developed based on the traditional bluetooth and is different from the traditional module, and the most important characteristic is that the cost and the power consumption are reduced.

In the process of establishing the bluetooth connection, the bluetooth device initiating the request for establishing the bluetooth connection is defined as a Central (Central) device, and the bluetooth device accepting the request for establishing the bluetooth connection is defined as a Peripheral (Peripheral) device.

The digital car key using the NFC communication method has the following problems: 1) The non-inductive operation cannot be realized, and the user experience is poor. Specifically, when the user is unlocking the car lock, the user needs to take out the mobile phone and touch NFC sensing areas such as a car door frame and a vehicle rearview mirror to complete unlocking operation. But the user also needs to take out the cell-phone and touch NFC induction zone and just can lock the car when locking the car, experiences inconsistent with current traditional entity car key, and user's operation complexity is higher. 2) The popularization rate of the NFC mobile phone is low, the NFC mobile phone accounts for about 3 market shares, the non-NFC mobile phone accounts for about 7 shares, and only a few users can experience the digital car key in the NFC communication mode.

The digital car key using the bluetooth communication method has the following problems: the bluetooth car key is not very convenient to use, and user experience is relatively poor. Use unblanking as an example, the user must take out the cell-phone, starts car key Application (APP), and after establishing the bluetooth with the vehicle and connecting, the user need the manual car key APP of clicking unblank the button and just can accomplish the operation. Although the car key APP of some car enterprises can be started and then automatically connected with the car through Bluetooth to complete the unlocking operation, the mobile phone system still can kill the car key APP resident in the background, so that the real non-inductive operation cannot be realized.

In addition, in consideration of data security, data of digital car keys using an NFC communication mode and a bluetooth communication mode generally exist in a security module (SE) of a mobile phone, and the SE of the mobile phone may include a SIM card of the mobile phone and an embedded SE; although an Android (Android) system provides an interface for accessing the SE by the APP of a third party, the implementation or adaptation of some mobile phone manufacturers to the interface for accessing the SE is not good, so that the access of a mobile phone card is not successful; the NFC function of the IOS system does not support direct access to data in the SIM card, and only supports access to data in the equipment SE, so that a digital car key is realized in the IOS system, and a car enterprise has to perform deep cooperation with a mobile phone manufacturer.

In summary, in the related art, in the process of unlocking the vehicle by using the digital vehicle key, the operation complexity of the user is high, and a solution of the digital vehicle key which is not felt by the user cannot be realized; also, compatibility of digital car keys in the related art is not ideal.

In view of the above technical problems, the technical solutions of the embodiments of the present application are provided.

The present application will be described in further detail below with reference to the drawings and examples. It should be understood that the examples provided herein are merely illustrative of the present application and are not intended to limit the present application. In addition, the following examples are provided for the purpose of carrying out some embodiments of the present application, and not for the purpose of providing all embodiments for carrying out the present application, and the technical solutions described in the embodiments of the present application may be implemented in any combination without conflict.

An embodiment of the present application provides a vehicle control method, and fig. 1 is a flowchart of the vehicle control method provided in the embodiment of the present application, and as shown in fig. 1, the flowchart may include:

step 101: after the user terminal is successfully paired with the target vehicle, the first Bluetooth device generates digital vehicle key data of the target vehicle; the digital vehicle key data includes asymmetric key data.

In this embodiment, the user terminal may be a mobile phone using an android system or an IOS system, the first bluetooth device is a device in the user terminal, the first bluetooth device may be a device using a conventional bluetooth module or a BLE module, and the first bluetooth device may be a device using a conventional bluetooth module or a BLE module; the target vehicle comprises a vehicle-mounted Bluetooth module which is in communication connection with the first Bluetooth device, and the vehicle-mounted Bluetooth module in the target vehicle can be recorded as a second Bluetooth device.

In one example, the first bluetooth device may be a bluetooth SIM card. The Bluetooth SIM card is obtained by adding a BLE communication module on the basis of a traditional SIM card, not only has all functions of the traditional SIM card, but also can be connected with an external Bluetooth module (such as a mobile phone Bluetooth module and a vehicle-mounted Bluetooth module) through a Bluetooth communication interface to carry out data transmission. The Bluetooth SIM card integrates a Bluetooth chip and can establish Bluetooth connection with a mobile phone terminal or a vehicle.

In the embodiment of the application, the second bluetooth device in the target vehicle has a bluetooth signal reading capability, and the second bluetooth device can perform bluetooth connection with the first bluetooth device of the user terminal and perform data communication with the first bluetooth device of the user terminal.

In practical application, the user terminal can send a pairing request with a pairing certificate to a target vehicle after establishing Bluetooth connection with the target vehicle; after receiving the pairing request, the target vehicle can check the pairing state according to the pairing certificate, and when determining that the target vehicle is paired with any Bluetooth device, the pairing process is terminated; terminating the pairing process when the pairing certificate is determined to be wrong; when the pairing certificate is determined to be correct, a pairing success verification result can be sent to the user terminal; after receiving the successful pairing check result, the user terminal generates indication information indicating that asymmetric key data is generated, and the first bluetooth device can generate asymmetric key data according to the indication information, namely digital vehicle key data of the target vehicle.

For example, the pairing credential may be a manufacturer-defined credential for the target vehicle that serves to identify the holder of the user terminal as the owner of the target vehicle, e.g., the pairing credential may be an Identity Document (ID) or other identification of the target vehicle. In practical application, after the user purchases the target vehicle, the manufacturer of the target vehicle may increase the corresponding pairing certificate to the owner of the target vehicle, so that the owner of the target vehicle may use the pairing certificate to pair the user terminal and the target vehicle.

In the embodiment of the application, the asymmetric key data comprises public key data and private key data, and the public key data and the private key data are a pair of data.

Step 102: the first bluetooth device transmits public key data of the asymmetric key data to the target vehicle.

Step 103: the target vehicle receives the public key data sent by the first bluetooth device.

Step 104: after the first Bluetooth device establishes Bluetooth connection with a target vehicle, signing preset data by using private key data of asymmetric key data to obtain signed data; and transmitting the signature data to a target vehicle through the Bluetooth connection.

In practical application, the target vehicle may be used as a central device to discover peripheral devices around, and when the peripheral device discovered by the target vehicle is a first bluetooth device, a bluetooth connection is established with the first bluetooth device.

The preset data may be, for example, a random number, a timestamp, or some random combination data, and the content of the preset data is not limited in the embodiments of the present application.

Step 105: the target vehicle receives signature data sent by the first Bluetooth device; and verifying the signature of the signature data by using the public key data to obtain a signature verification result.

For example, when signature data is verified by using public key data, a signature verification result indicating that signature verification fails may be obtained, or a signature verification result indicating that signature verification passes may be obtained.

Step 106: and the target vehicle performs unlocking of the target vehicle when the verification result shows that the verification passes.

In practical applications, the user terminal and/or the target vehicle may include a Processor, and the Processor may be at least one of an Application Specific Integrated Circuit (ASIC), a Digital Signal Processor (DSP), a Digital Signal Processing Device (DSPD), a Programmable Logic Device (PLD), a Field Programmable Gate Array (FPGA), a Central Processing Unit (CPU), a controller, a microcontroller, and a microprocessor.

It can be seen that, in the embodiment of the application, the target vehicle receives the signature data based on the bluetooth connection, and the signature verification can be performed on the signature data according to the pre-acquired public key data, so that the unlocking of the target vehicle is automatically executed when the signature verification passes. Moreover, the signature verification is carried out on the signature data, so that the safety of unlocking the vehicle is improved.

Further, the vehicle control method according to the embodiment of the present application may be applicable to a user terminal that does not support a machine card access and a user terminal that does not support an NFC function, that is, the vehicle control method according to the embodiment of the present application has high compatibility.

Furthermore, in the embodiment of the application, the Bluetooth connection can be directly established between the target vehicle and the first Bluetooth device, and the Bluetooth connection does not need to be established through the mobile phone APP, so that the problem that the unlocking of the vehicle cannot be realized due to the fact that the mobile phone APP at the background is killed by a mobile phone system can be avoided.

In some embodiments, after the pairing of the user terminal and the target vehicle is successful, the process of establishing the bluetooth connection between the first bluetooth device and the target vehicle may include:

step A1: the first bluetooth device transmits a Media Access Control (MAC) address of the first bluetooth device to the target vehicle.

Step A2: the target vehicle receives the MAC address sent by the first bluetooth device.

For example, the first bluetooth device may transmit the public key data of the asymmetric key data and the MAC address of the first bluetooth device together to the target vehicle, or the first bluetooth device may sequentially transmit the public key data of the asymmetric key data and the MAC address of the first bluetooth device to the target vehicle.

Step A3: the target vehicle determines the MAC address of the currently searched bluetooth device.

In practical applications, the target vehicle may be used as a central device to search for peripheral bluetooth devices.

Step A4: after determining that the MAC address of the currently searched Bluetooth device is the same as the MAC address of the first Bluetooth device, the target vehicle determines that the currently searched Bluetooth device is the first Bluetooth device, and sends a Bluetooth connection establishment request to the first Bluetooth device

In the embodiment of the application, the target vehicle can compare the MAC address of the currently searched Bluetooth device with the MAC address of the first Bluetooth device, and when the MAC address of the currently searched Bluetooth device is different from the MAC address of the first Bluetooth device, the first Bluetooth device is determined not to be searched; when the MAC address of the currently searched bluetooth device is the same as the MAC address of the first bluetooth device, it may be determined that the first bluetooth device is searched.

Step A5: and the first Bluetooth device establishes Bluetooth connection with the target vehicle after receiving a Bluetooth connection establishment request sent by the target vehicle.

Therefore, the first Bluetooth device can be searched by comparing the MAC address of the currently searched Bluetooth device with the predetermined MAC address of the first Bluetooth device, and the Bluetooth connection between the first Bluetooth device and the target vehicle can be accurately established.

In some embodiments, after establishing the bluetooth connection with the first bluetooth device, the target vehicle may perform a lock down of the target vehicle upon determining that the bluetooth connection is broken.

Exemplarily, when the distance between the first Bluetooth device and the target vehicle exceeds the maximum sensing distance of Bluetooth connection, the disconnection of the Bluetooth connection is confirmed, and at this time, the target vehicle can automatically perform lock falling, so that the safety of the vehicle is improved.

For example, when the distance between the target vehicle and the first bluetooth device exceeds the maximum sensing distance of bluetooth connection, determining that the bluetooth connection is disconnected, determining the position of the user terminal before the bluetooth connection is disconnected, and if the user terminal is in the target vehicle before the bluetooth connection is disconnected, not performing lock-down of the target vehicle; and if the user terminal is outside the target vehicle before the Bluetooth connection is disconnected, executing automatic locking of the target vehicle.

It can be seen that this application embodiment can be when the bluetooth connection disconnection, the lock that falls of target vehicle is carried out automatically, because this application embodiment realizes the lock that falls of target vehicle on the basis that need not the user and click the key APP lock that falls button, consequently, has reduced user's operation complexity, has realized the operation that the user does not feel that the vehicle falls to lock.

Furthermore, in the embodiment of the application, when the target vehicle is disconnected from the Bluetooth of the first Bluetooth device, the target vehicle can be automatically locked, and the Bluetooth connection does not need to be established through the mobile phone APP, so that the problem that the vehicle cannot be locked due to the fact that the mobile phone APP at the background is killed by a mobile phone system can be avoided.

In some embodiments, the user terminal sends a deletion instruction of the digital car key data to the target vehicle; under the condition that the target vehicle receives a deletion instruction of the digital vehicle key data sent by the user terminal, deleting the public key data according to the deletion instruction to obtain an execution result of deletion operation; the target vehicle sends an execution result of the deletion operation to the first Bluetooth device; and the first Bluetooth device deletes the digital vehicle key data of the target vehicle after receiving the execution result of the deletion operation.

In practical application, a user can input a deletion instruction of digital vehicle key data to a user terminal according to actual requirements under the condition that the user does not need to unlock or lock the vehicle based on the digital vehicle key.

It can be seen that, the embodiment of the application can delete corresponding digital car key data in the target car and the first bluetooth device respectively according to actual requirements.
