Detailed Description

In addition, the embodiments of the present invention and the features of the embodiments may be combined with each other without conflict.

The present invention will be described in detail below with reference to the accompanying drawings in conjunction with embodiments.

Example one

Fig. 1 is a schematic flow chart of a vehicle entering and starting method according to a first embodiment of the present invention, which is applied to a vehicle end and includes the following steps:

and S100, when a preset vehicle entering condition is met, acquiring an NFC secret key sent by a vehicle APP of the mobile terminal outside the vehicle based on the NFC function.

Wherein, with car APP with the vehicle carries out the special APP of information interaction in order to realize that the vehicle gets into and starts, the manufacturer can carry out the custom name to this APP. In addition, the NFC key is used for verifying the user identity so as to determine whether the user of the current mobile terminal has the vehicle using authority.

Further, the mobile terminal is, for example, a tablet computer, a notebook, a smart phone, or the like, and the embodiment of the present invention mainly takes a mobile phone as an example.

Wherein the vehicle entry condition is used to characterize the ability and need to have access to the vehicle (or unlock the doors), which preferably includes the following conditions: 1) the mobile terminal starts the NFC function, and the vehicle using APP is in a running state; 2) the vehicle is in a fortifying state, and the door, the window and the like of the vehicle are all locked in the fortifying state; and 3) the vehicle is in a power OFF mode (OFF mode). Wherein condition 1) is used to indicate that the mobile terminal has the capability of unlocking the door, and conditions 2) and 3) are used to indicate that the vehicle is indeed in a state that requires unlocking the door.

Accordingly, for step S100, for example, an NFC card reader may be installed at a suitable position on the vehicle housing to enable the user to swipe a mobile phone, which needs to have an NFC function and is installed with the car APP; when the NFC function of the mobile phone is started and the APP of the vehicle runs, and the vehicle is in the defense state of the vehicle door lock and the static state of the power OFF mode, the mobile phone is close to the NFC card reader, so that the NFC card reader obtains the NFC secret key of the mobile phone based on NFC function transmission through induction.

And step S200, verifying the obtained NFC secret key, and controlling the vehicle to unlock the vehicle door after the verification is successful.

For example, the mobile phone may encrypt through its built-in SE chip to generate the NFC key for verifying the user identity, and after acquiring the NFC key, the NFC card reader sends the NFC key to the NFC controller (or other type of controller) in the vehicle, and the NFC controller decrypts the NFC key through its own SE chip to verify the user identity. In which, an asymmetric encryption international algorithm (e.g., RSA2048, ECC256, etc.) may be used to perform corresponding encryption or decryption. Further, after the user identity is verified, the NFC controller may send an NFC unlocking instruction to a Body controller (Body Control Module, referred to as BCM or KBCM for short), and the KBCM may respond to the NFC unlocking instruction to implement a door unlocking function.

And S300, responding to the success of unlocking, controlling a Bluetooth module in the vehicle to start and carrying out Bluetooth connection with the vehicle APP.

In a preferred embodiment, the Bluetooth module may be a Bluetooth Low Energy (BLE) module.

In a preferred embodiment, after controlling the vehicle to unlock the door in step S200, a flag indicating that the NFC entry is successful may be further generated. Accordingly, in this step S300, the success of the unlocking can be determined by detecting the flag bit.

Thus, taking the BLE module as an example, after the door is successfully unlocked or the flag is detected, the BLE module is activated again to enter the operating mode, and before that, the BLE module may be in the preset power saving mode (or called sleep mode). As for the transition between the operating mode and the power saving mode, fig. 2 can be understood by referring to fig. 2, where fig. 2 is a schematic diagram of mode transition of the BLE module in the embodiment of the present invention, and the mode transition includes an operating mode, a power saving mode and an awake mode, where in the power saving mode, the BLE module enters a sleep state, power consumption is minimum, the operating mode corresponds to the start of the BLE module, power consumption is relatively large, and the awake mode can be understood as a "standby" mode between the power saving mode and the operating mode. With reference to fig. 2, mode transition of the BLE module mainly includes the following aspects:

1) when the BLE module is in the wake-up mode, when the vehicle is in a defense state and a first condition that Bluetooth is not connected occurs, the BLE module jumps to a power saving mode to save power to the maximum extent;

2) when the BLE module is in the power saving mode, when the NFC enters the power saving mode successfully and a second condition that the vehicle network is in the wake-up state occurs, the BLE module jumps to the wake-up mode so as to enable the BLE module to be in a standby state at any time;

3) when the BLE module is in the wake-up mode, when a third condition of successful bluetooth connection occurs, the BLE module jumps to the working mode, where the bluetooth connection here refers to bluetooth connection between the BLE module and another device (e.g., the above-mentioned mobile phone);

4) when the BLE module is in a working mode and a fourth condition of disconnection of Bluetooth connection occurs, the BLE module jumps to the wake-up mode;

5) when the BLE module is in the working mode, when the Bluetooth connection is disconnected and a fifth condition that the vehicle enters a fortification state occurs, the BLE module jumps to the power saving mode to save power.

In view of the above, the BLE module just gets into economize on electricity mode after the vehicle is fortified, and only after NFC gets into successfully, just can awaken up the BLE module to can practice thrift the electric quantity of vehicle battery, guarantee that the user vehicle can deposit the longer time.

Further, for a mobile terminal, taking a smart phone as an example, APP thereon is susceptible to being affected by a power saving mode of the smart phone and the like to stop running in the background, and this phenomenon is generally referred to as APP being killed. Obviously, this phenomenon can influence the bluetooth connection of car APP with the bluetooth module in the car and cell-phone.

In this regard, in a preferred embodiment, the step S300 may include: trigger bluetooth module with mobile terminal's bluetooth is connected, so that mobile terminal is automatic awakens up use car APP, in order to establish bluetooth module with use the bluetooth connection between the car APP. The bluetooth of the mobile phone is the function of the mobile phone as well as the NFC function of the mobile phone, and is irrelevant to whether the car APP is installed on the mobile phone.

For example, after the NFC successfully enters, the vehicle-side BLE module is triggered to be quickly connected to the bluetooth of the mobile phone, for example, through a bluetooth out-of-band connection mode. If this moment, the car APP of cell-phone is in the killed state, then awakens up the APP automatically through the cell-phone, finally successfully establishes the bluetooth of car APP and connects with cell-phone end car BLE.

And S400, when the vehicle meets a preset vehicle starting condition, responding to a vehicle starting operation of a user, and controlling the vehicle to start.

Wherein the vehicle start condition includes: the Bluetooth module positions the mobile terminal in the vehicle based on the Bluetooth connection. For example, the bluetooth module is taken as a BLE module, and the positioning is implemented by, for example, detecting a bluetooth RSSI (Received Signal Strength Indication) by the BLE module. In this manner, the vehicle start condition is such that the control of the vehicle start in step S400 is performed in a scene where the mobile terminal is in the vehicle.

In a preferred embodiment, the vehicle start condition may further include: the vehicle is in neutral (N gear) or park (P gear); and the BLE and the vehicle APP are successfully authenticated. Wherein authentication between the BLE and the vehicle APP is intended to determine a correct pairing between the Bluetooth module and the vehicle APP.

The vehicle start operation by the user includes, for example, depressing a brake and depressing a one-touch start switch. For step S400, for example, after the preset vehicle start condition is satisfied, the user presses the brake and presses a one-key start switch to send a vehicle start command to the KBCM, and the KBCM starts the vehicle in response to the vehicle start command.

It can be seen that, in step S400, vehicle starting is achieved in the scenario where the mobile terminal is located inside the vehicle, and then, returning to step S100, it can be seen that vehicle unlocking is achieved in the scenario where the mobile terminal is located outside the vehicle, so that it can be seen that the embodiment of the present invention achieves a scheme of unlocking the vehicle by using NFC outside the vehicle and starting the vehicle by using BLE inside the vehicle, that is, a combination of NFC and BLE in vehicle entering and starting is achieved, taking a mobile phone as an example, the combination may have at least the following advantages:

1) NFC is adopted for entering outside the automobile, BLE is adopted for starting inside the automobile, the cost is low, and the automobile can enter by utilizing the NFC powerless induction principle when the mobile phone is in power failure;

2) the NFC enters the successful zone bit as a precondition for the start of the BLE in the vehicle, so that the safety of the start in the vehicle is greatly improved;

3) the method combining BLE and NFC is adopted, the disadvantages that Bluetooth is easy to be attacked by relay equipment, the power consumption of a vehicle is large, an NFC starting area is limited and the like are successfully avoided, the safety of a user entering the vehicle is solved, and the convenience of starting the vehicle after the user enters the vehicle is also considered.

In summary, the vehicle entering and starting method provided by the embodiment of the invention combines the NFC and the BLE to realize the entering and starting of the vehicle, and can significantly improve the user experience.

Other implementation details and effects of the vehicle entering and starting system in the third embodiment of the present invention can be found in the first embodiment and the second embodiment, and are not described herein again.

Example four

The fourth embodiment is an application example, in which the mobile terminal 200 takes a mobile phone as an example and the bluetooth module takes a BLE module as an example, and vehicle entry and starting are realized based on the solutions of the first embodiment, the second embodiment, or the third embodiment. Referring to fig. 5-7, this embodiment four consists essentially of four parts of functional logic.

First, NFC enters the function.

Fig. 5 is a schematic flowchart of implementing NFC entry in the fourth embodiment of the present invention. Referring to fig. 5, the method may specifically include the following steps:

step S510, determining preconditions, including: the method comprises the steps of starting the NFC of the mobile phone, running the APP of the mobile phone (including background running), fortifying the vehicle and turning OFF the power mode of the vehicle.

And step S520, executing a trigger condition, namely that the mobile phone is close to the NFC card reader outside the vehicle.

Step S530, determining whether the NFC card reader successfully senses, if not, ending the process, and if so, executing step S540.

And step S540, the NFC card reader outside the vehicle sends the NFC secret key encrypted by the SE chip of the mobile phone to the BLE module through the CAN bus.

The NFC secret key is a digital key, and the BLE module is integrated with the NFC controller.

In step S550, the BLE module decrypts the signal through the built-in SE chip.

Step S560, determining whether the decryption is successful, if not, ending the process, and if so, executing step S570.

The decryption process is essentially a process of verifying the identity of the user, and the encryption and decryption process may use an asymmetric encryption international algorithm, such as RSA2048, ECC256, and the like.

Step S570, the in-vehicle BLE module sends an NFC unlocking instruction to the KBCM, and the KBCM drives the door lock to unlock.

Accordingly, the vehicle entering is realized based on the NFC outside the vehicle through the steps S510 to S570, the NFC belongs to near field communication, the effective distance of entering identification is about 10cm, and therefore the vehicle entering identification cannot be attacked by the relay equipment and the safety is good. In addition, the operation of the NFC is not limited by whether the mobile phone is powered on or not, and the NFC card reader can still sense the NFC signal of the mobile phone even if the mobile phone is powered off through testing.

And II, a BLE starting function.

Figure 6 is a schematic flow chart of implementing BLE activation according to a fourth embodiment of the present invention. Referring to fig. 6, the method may specifically include the following steps:

step S610, determining whether the NFC entry of the mobile phone is successful, if not, ending the process, and if so, executing step S620.

Step S620, determining whether other preconditions are satisfied, if not, ending the process, and if so, executing step S630.

Wherein the other preconditions comprise: the vehicle BLE and the mobile phone are successfully connected through the vehicle APP Bluetooth, the BLE positions the mobile phone in the vehicle, the vehicle gear is in the P/N gear, and the BLE and the mobile phone APP are authenticated.

Step S630, a trigger condition is executed, i.e., the brake is pressed and a key start switch of the vehicle is pressed.

And step S640, performing anti-theft authentication between the BLE module and the KBCM.

Wherein, this theftproof authentication is used for preventing that the BLE module of a certain car is stolen for interacting with other vehicles' KBCM, and has started other vehicles, further causes the stolen of this other vehicles. For example, for each vehicle, before leaving the factory, the anti-theft authentication can be realized by performing unique AES128 symmetric encryption between the BLE module and the KBCM.

Step S650, determining whether the anti-theft authentication is successful, if not, ending the process, and if so, executing step S660.

And step S660, the KBCM sends a starting signal to the engine control unit to realize vehicle starting.

Accordingly, the purpose that the vehicle is started in the vehicle based on BLE is achieved through the steps S610 to S660, wherein one of the precondition that the BLE is started in the vehicle is that the NFC enters successfully, and the safety of the start in the vehicle is greatly improved.

Automatic awakening function of vehicle APP

Fig. 7 is a schematic flow chart of implementing automatic wake-up of the car APP in the fourth embodiment of the present invention. Referring to fig. 7, under the precondition that the mobile phone end is in the scanning mode in which the NFC and the bluetooth switch is turned on, the vehicle end is in the broadcasting mode (or Polling mode) for sending the bluetooth broadcast signal, and the NFC successfully enters, the method may specifically include the following steps:

and step S710, the vehicle end confirms by the mobile phone.

For example, the NFC card reader outside the vehicle notifies the BLE module to identify the corresponding cell phone.

In step S720, the BLE module performs RSSI detection to find bluetooth of the mobile phone.

For example, in the bluetooth out-of-band connection mode, the RSSI determines whether a mobile phone is present in the vehicle by detecting the bluetooth RSSI, so as to connect with the bluetooth of the mobile phone.

Accordingly, the mobile phone is quickly discovered by the vehicle side through the steps S710 and S720.

Step S730, if the car using APP for the mobile phone end is in the killed state, the mobile phone starts to connect and confirm to activate the car using APP in response to the BLE module.

So, realized the cell-phone and awaken up to car APP's quick automation.

Step S740, establishing a bluetooth connection with the vehicle end BLE by using the vehicle APP, and more specifically, establishing a BLE connection based on a gatt (generic Attribute profile) protocol.

Wherein GATT is a common specification for sending and receiving very short data segments over a bluetooth connection.

So, realized with the quick connection of car APP and vehicle end BLE module.

Through the steps, the automatic activation function of the vehicle APP is achieved, after the APP is killed by the mobile phone background, the connection can be established through the vehicle Bluetooth and the mobile phone Bluetooth quickly after the APP is swiped into the door by NFC, the vehicle APP can be rapidly called through the mobile phone, the problem of complaint caused by failure of the after-sale Bluetooth key due to the fact that the vehicle APP background is killed can be solved, and user experience is guaranteed.

Four, power saving mode

Referring to fig. 2, in the fourth embodiment of the present invention, the BLE module enters a sleep state after the vehicle is armed, the power saving mode is turned on, the real-time Polling is not performed any more, and the BLE module is awakened only after the NFC successfully enters, so that the sleep current of the vehicle can be greatly reduced, and the number of days for which the vehicle is stored is increased.
