Detailed Description

In order to make the objects, technical solutions and advantages of the present application more apparent, the technical solutions of the present application will be described in detail and completely with reference to the following specific embodiments of the present application and the accompanying drawings. It should be apparent that the described embodiments are only some of the embodiments of the present application, and not all of the embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present application.

Intellectuality, sharization and digitization are big environmental trends of present intelligent network car, and it is also the same to the vehicle key, and the comparatively common intelligent key is the digital key at present, and it can use mobile device (mainly cell-phone) to carry out vehicle control as the carrier, and then lets the user still can enjoy the experience of radio frequency key under the condition need not to carry the entity key. At present, a vehicle-mounted digital key control system of a vehicle can only log in one user, and the user is often a driver, so that the vehicle can only automatically adjust vehicle-mounted equipment corresponding to a main driving seat (namely, a seat of the driver) according to personal conditions of the driver, such as air conditioning control, music playing control, seat control and the like, but cannot provide corresponding personalized control for the vehicle-mounted equipment corresponding to seats where other passengers are located on the vehicle, and the experience of the passengers in the vehicle is poor.

In view of this, an embodiment of the present application provides an onboard digital key control system, as shown in fig. 1, the system includes: the vehicle body area control system comprises a digital key controller 1, a plurality of positioning devices 2 and a vehicle body area controller 3, wherein each positioning device 2 is used for acquiring first position information of at least two target objects and sending the first position information to the digital key controller 1. The digital key controller 1 is configured to determine terminal device identifiers of at least two target objects, and send the terminal device identifiers and the first position information to the body area controller 3. The vehicle body area controller 3 is configured to determine control parameters of the vehicle-mounted device corresponding to each target object according to the terminal device identifier and the first position information, and control the corresponding vehicle-mounted device based on the control parameters of each vehicle-mounted device.

The working principle of the vehicle-mounted digital key control system provided by the embodiment of the application is as follows:

the method comprises the steps that communication connection is established between the digital key controller 1 and terminal devices of at least two target objects in advance, when the terminal devices carried by the at least two target objects are close to a vehicle, the plurality of positioning devices 2 acquire first position information of the at least two target objects, and the first position information is sent to the digital key controller 1. In this process, the digital key controller 1 automatically obtains digital keys used by the terminal devices of the at least two target objects (for example, if an application program for connecting with and controlling the vehicle exists in the terminal devices of the target objects, the digital keys are account numbers used for logging in the application program, and have a preset corresponding relationship with the identities of the target objects), determines the terminal device identifications of the at least two target objects, and sends the terminal device identifications and the first location information to the body area controller 3. Subsequently, the vehicle body area controller 3 may determine the control parameter of the vehicle-mounted device corresponding to each target object according to the terminal device identifier and the first position information, and control the corresponding vehicle-mounted device based on the control parameter of each vehicle-mounted device.

The control parameters of the vehicle-mounted device may include response time and preference characteristics of the target object, and at this time, the vehicle body domain controller 3 is configured to determine the response time based on the first position information; and determining preference characteristics of each target object based on the terminal equipment identification, and executing control operation on corresponding vehicle-mounted equipment after response time based on each preference characteristic. In a specific implementation, for example, when the target object is close to the vehicle and when the target object is 4m away from the vehicle door, the response time is determined to be 10s, then, after 10s, corresponding control operation may be performed on the vehicle-mounted device according to the preference characteristics of the target object, for example, the vehicle door is opened after 10s, the seat back is adjusted after 10s, and the like.

In practical application, the digital key controller 1 may be in communication connection with terminal devices of at least two target objects at the same time, preference characteristics corresponding to different target objects are also different, and when at least two target objects are approaching or entering a vehicle at the same time, the vehicle body area controller 3 may control vehicle-mounted devices at positions corresponding to the target objects according to the preference characteristics corresponding to each target object after response time. Wherein, the vehicle-mounted equipment can be: seat adjusting motor, atmosphere fluorescent tube, door window, sunshade window, air conditioner etc.. For the preference feature, for example, the preference feature may be a video entertainment feature, a door and window control feature, a cabin adjustment feature, a temperature control feature, a light interaction feature, etc., which are not listed herein. Exemplified by the door and window control feature therein, for example, a user prefers to have the window half-way open during vehicle driving.

The vehicle-mounted digital key control system provided by the embodiment of the application can determine the terminal equipment identifications of at least two target objects, namely the identities of the target objects by setting the digital key controller 1. By using each positioning device 2 to respectively acquire the first position information of at least two target objects, the control of the corresponding vehicle-mounted device based on the first position information is facilitated. By setting the vehicle body area controller 3, the control parameters of the vehicle-mounted equipment corresponding to each target object can be respectively determined according to the terminal equipment identification and the first position information, and then the corresponding vehicle-mounted equipment is controlled based on the control parameters of each vehicle-mounted equipment, namely, the vehicle-mounted equipment corresponding to the terminal equipment can be individually controlled according to different target objects, so that the control of the vehicle-mounted equipment corresponding to the main driving position is finished, the vehicle-mounted equipment corresponding to the position of any passenger in the vehicle can be correspondingly and individually controlled, and the passenger can have better riding experience at any position in the vehicle.

It should be understood that, in the embodiment, each target object carries a terminal device, and the terminal device may include: mobile phones, Personal Computers (PC), tablet computers, notebook computers, wearable devices, and the like. The positioning device 2 may be a positioning antenna.

The communication connection of the digital key controller 1 with the terminal device of the target object may be a bluetooth connection and/or an ultra wideband connection. Specifically, a Bluetooth Low Energy (BLE) technology may be used to implement "Bluetooth connection", and an Ultra Wide Band (UWB) technology may be used to implement "Ultra Wide Band".

Regarding the arrangement positions of the digital key controller 1 and the plurality of positioning devices 2 on the vehicle, for example, as shown in fig. 2, two front positioning devices 2 may be disposed on the left and right sides of a front bumper of the vehicle, two rear positioning devices 2 may be disposed on the left and right sides of a rear bumper of the vehicle, and a center positioning device 2 may be disposed on a center line of a ceiling of the vehicle near an upper portion of a middle seat in the rear row. The digital key controller 1 is disposed at a position in the middle of a front seat of a vehicle. By such arrangement, when a plurality of target objects approach the vehicle from different directions, no matter what terminal equipment only having a bluetooth function and/or terminal equipment having a UWB function is carried, more than two positioning devices 2 are used for accurately positioning the target objects, and accurate positioning of the positions of the target objects is ensured. Of course, the present invention is not limited to this, and other layout methods may be used as long as the above-described functions can be achieved. In order to ensure the user experience, a plurality of terminal devices may be located in a channel listening or scanning manner, specifically, different terminal devices may be located in a carousel manner, and the communication connection distance and the location distance between the terminal devices may be set to be within 35 meters, for example, it may be 20 meters, 30 meters, and the like.

It should be noted that the digital key controller 1 also has a positioning function, and can acquire the digital key ranging information corresponding to the terminal device according to the self-positioning function.

When the target object is located outside the vehicle, the target object can be located mainly by two front locating devices 2 and two rear locating devices 2, and the other locating device in the vehicle in the middle plays a role in auxiliary location so as to improve the accuracy of location. In specific implementation, according to the distance measurement information and the digital key distance measurement information corresponding to the target object terminal device, which are acquired by the two front positioning devices 2 and the two rear positioning devices 2, the position information of the terminal device outside the vehicle (i.e., the position information of the target object) is determined by combining a preset positioning algorithm. If another positioning device 2 centered in the vehicle is used in the process, the acquired ranging information corresponding to the terminal device is sent to the digital key controller 1 to perform subsequent position information determination operation. At this time, the position information and the terminal device identifier of the terminal device may be sent to the body area controller 3, and the body area controller 3 is used to control the door close to the target object to be automatically opened (i.e., to start the automatic welcome function of the vehicle).

When the target object is located in the vehicle, the target object can be located mainly by the aid of the locating device 2 arranged in the center of the vehicle and the digital key controller 1, and the other two front locating devices 2 and the other two rear locating devices 2 play a role in assisting in locating, so that locating accuracy is improved. During specific implementation, the digital key controller 1 may obtain digital key ranging information corresponding to the in-vehicle terminal device according to a self-positioning function, and determine a position of the terminal device in the vehicle (i.e., a position of the target object in the vehicle) according to the digital key ranging information and ranging information corresponding to the in-vehicle terminal device obtained by the positioning device 2 located in the center of the vehicle, in combination with a preset positioning algorithm. If two other front positioning devices 2 and two rear positioning devices 2 are used in the process, the obtained ranging information corresponding to the in-vehicle terminal device is sent to the digital key controller 1 to perform subsequent position information determination operation.

When a plurality of target objects approach the vehicle from different directions, no matter whether the target objects carry terminal equipment with only a bluetooth function or terminal equipment with a UWB function, or carry terminal equipment with both the bluetooth function and the UWB function, more than two positioning devices 2 are used for accurately positioning the target objects. Of course, the present invention is not limited to this, and other layout methods may be used as long as the above-described functions can be achieved.

It should be understood that, since other people (i.e., people who have not previously established a communication connection with the digital key controller 1) may also make a communication connection with the digital key controller 1 of the vehicle through their terminal devices when they walk within a preset range near the vehicle, thereby performing a control operation on the vehicle, the risk of vehicle theft is easily generated. In view of this, the digital key controller 1 according to the embodiment of the present application is configured to trigger the plurality of positioning devices 2 to start operating when determining that the attribute information of the target object is valid (where the attribute information of the target object is identity information of the target object) according to the digital key. For example, assuming that the terminal device of the user "zhang san" has previously established a communication connection with the digital key controller 1 of the target vehicle, when zhang san "reaches a preset range near the vehicle, the digital key controller 1 automatically establishes a communication connection with the terminal device of zhang san" and determines the identity of zhang san "according to the digital key, and if there is no problem, the positioning devices 2 are triggered to start working.

It should be noted that the at least two target objects include a master target object and at least one slave target object, where the master target object is configured to perform attribute information authentication processing on the at least one slave target object, and determine the master target object and the at least one slave target object subjected to attribute information authentication processing as target objects whose attribute information is valid. In practical application, after the vehicle is delivered, a vehicle owner can realize human-vehicle association through the digital key system, the vehicle is activated through the terminal device to become a main target object, and the background cloud end can simultaneously establish a vehicle owner account number and open the personalized set permission. The main target object can authorize the use permission of the vehicle to family, relatives, friends, colleagues and the like (namely, attribute information authentication processing is carried out on at least one slave target object), namely, the background cloud end can establish corresponding accounts for shared users at the same time, and the personalized set permission is opened.

In order to ensure that the position information of the target object sent to the body area controller 3 is the latest position information of the target object in consideration of the situation that the target object may have changed seats after getting on the vehicle, in the embodiment of the present application, as shown in fig. 1, the system further includes: and the camera 4 is connected with the vehicle body area controller 3. The camera 4 is used for collecting an in-vehicle image, and sending the collected in-vehicle image to the vehicle body domain controller 3, wherein the in-vehicle image contains a target object. Each positioning device 2 is configured to detect second position information corresponding to the target object according to the terminal device identifier, and send the second position information to the digital key controller 1. The digital key controller 1 is configured to send the second location information and the terminal device identifier to the body area controller 3. The vehicle body area controller 3 is used for identifying the position movement information of the terminal equipment corresponding to any target object in the image in the vehicle, and determining the validity of the second position information based on the position movement information; and if the second position information is determined to be effective, respectively determining the control parameters of the vehicle-mounted equipment corresponding to the target object according to the second position information, and controlling the corresponding vehicle-mounted equipment based on the control parameters.

For ease of understanding, a specific implementation is given below:

it is assumed that the time for acquiring the first location information is a first time, and the time for acquiring the second location information is a second time. Taking the target object "liquad" as an example, when liquad is just getting on (first time), the digital key controller 1 determines that the first seat corresponding to the first position information thereof is the rear left seat. After a period of time (i.e., the second time), the second seat is moved from the left seat of the rear row to the right seat of the rear row (i.e., the second position information is determined), and at this time, the second position information and the terminal device identifier are sent to the body area controller 3. Of course, the "first time" and the "second time" may be other times, but not limited to this, for example, the first time is the time when the user reaches the left front door, and the second time is the time when the user reaches the right rear door after the user has performed the position adjustment after driving the vehicle for a certain period of time.

It should be understood that, since the digital key controller 1 is adopted to determine the second position information of the target object according to the second ranging information sent by the plurality of positioning devices 2 in the embodiment of the present application, if the terminal device of the target object moves in the vehicle but the target object does not move (i.e. two users in the vehicle exchange mobile phones), the wrong second position information of the target object is easily sent to the body area controller 3, which further affects the user experience.

Based on this, the present application uses the above-described camera 4. In specific implementation, for example, suppose that two users, namely "three opening" and "four luggage" are shared on the vehicle, the "three opening" is seated on the left side of the front row when the vehicle is parked, and the "four luggage" is seated on the right side of the front row when the vehicle is parked. And after a period of time, the digital key controller 1 is configured to determine second position information of "zhang san" and "lie san" from the second ranging information transmitted from the plurality of positioning devices 2, and transmit the second position information and the terminal device identification to the body area controller 3. At this time, the in-vehicle image is collected by the camera 4 connected to the body area controller 3, and the collected in-vehicle image is transmitted to the body area controller 3. Whether the behavior of the mobile terminal device exists in Zhang three and Liquan in the image in the car is identified through the car body domain controller 3, namely whether the Zhang three and Liquan interchange the terminal device or place the terminal device at other positions in the car. And if the fact that the Zhang three and the Liquan are not moved is recognized, and only the terminal equipment of the Zhang three and the Liquan is moved, determining that the second position information is invalid. And if the target object is identified to have no mobile terminal device behavior, for example, Zhang III changes the position in the vehicle, determining a second seat corresponding to the second position information of Zhang III, and controlling the vehicle-mounted device corresponding to the second seat according to the preference characteristics.

In the embodiment of the application, in order to save memory resources of the vehicle-mounted digital key control system, the corresponding relation between the terminal device identifier and the preference feature may be stored in the cloud server. As shown in fig. 1, the vehicle-mounted digital key control system further includes: cloud communication device 5. The cloud communication device 5 is connected to the body area controller 3. The vehicle body area controller 3 is configured to send a data acquisition request including a terminal device identifier to the cloud server through the cloud communication device 5, so as to acquire a preference feature of each target object from the cloud server.

During specific implementation, after the vehicle body domain controller 3 receives the terminal device identification corresponding to the terminal device of the target object sent by the digital key controller 1, the data acquisition request containing the terminal device identification is sent to the cloud server through the cloud communication device 5, the preference feature of each target object can be acquired from the cloud server, and the method is convenient and fast.

In addition, in this application embodiment, the vehicle-mounted digital key control system further includes: the intelligent driving device (also called automatic driving device) and an automatic driving motor which is in communication connection with the intelligent driving device. When the target object is identified as a driver, the body domain controller 3 may transmit the preference characteristics of the target object to the smart driving apparatus so that it automatically drives the vehicle according to the driving style preferred by the target object. In this process, the autopilot motor is used to adjust the speed of travel of the vehicle in real time.

It should be noted that, in order to improve the signal transmission speed and the real-time performance of data communication among the components of the vehicle-mounted digital key control system of the present application, the communication modes among the digital key Controller 1, the plurality of positioning devices 2, the vehicle body Area Controller 3, and the cloud communication device 5 may all be set to Controller Area Network Communication (CAN).

Wherein, the digital key controller 1 and a plurality of positioning devices 2 respectively adopt private controller area network communication (namely private CAN communication); the digital key controller 1, the vehicle body area controller 3 and the cloud communication device 5 are communicated with each other through a public controller area network (namely, public CAN communication). In order to further improve the communication rate among the components of the vehicle-mounted digital key control system, the CAN communication in the application CAN be set as CAN FD communication. In practical application, the data synchronization of the digital key controller 1 and the plurality of positioning devices 2 CAN be ensured as long as the collision processing and arbitration mechanism of the CAN protocol is followed in the communication process.

The body area controller 3 and the vehicle-mounted device may use Local Interconnect Network (LIN) communication. It should be understood that the communication response time based on the local area internet is not as high as that of the CAN communication, the communication mode sensing is lower, the load rate of the whole vehicle CAN be reduced, and if the public CAN communication is adopted, the load rate is very high. Therefore, from the viewpoint of cost and load factor, the present application employs local area internet communication between the body area controller 3 and the in-vehicle device.

In order to improve the security of communication among the devices in the vehicle-mounted digital key control system in the embodiment of the application, encrypted communication can be adopted for communication modes of private controller local area network communication, public controller local area network communication and local area internet communication.

For the encryption communication mode, for example, a secret key CAN be added into a message of CAN communication when the whole vehicle is produced, and the secret key is encrypted and decrypted when the secret key is used for communicating messages. In addition, in order to ensure the security of the communication between the terminal device and the vehicle-mounted digital key control system, both communication modes can adopt encrypted communication.

Correspondingly, the embodiment of the application also provides a vehicle, which comprises the vehicle-mounted digital key control system in the embodiment.

In summary, the present application can determine the terminal device identifiers of at least two target objects, i.e. determine the identities of the target objects, by setting the digital key controller 1. By using each positioning device 2 to respectively acquire the first position information of at least two target objects, the control of the corresponding vehicle-mounted device based on the first position information is facilitated. By setting the vehicle body area controller 3, the control parameters of the vehicle-mounted equipment corresponding to each target object can be respectively determined according to the terminal equipment identification and the first position information, and then the corresponding vehicle-mounted equipment is controlled based on the control parameters of each vehicle-mounted equipment, namely, the vehicle-mounted equipment corresponding to the terminal equipment can be individually controlled according to different target objects, so that the control of the vehicle-mounted equipment corresponding to the main driving position is finished, the vehicle-mounted equipment corresponding to the position of any passenger in the vehicle can be correspondingly and individually controlled, and the passenger can have better riding experience at any position in the vehicle. Moreover, the digital key controller 1 and the plurality of positioning devices 2 are respectively communicated by adopting a private controller local area network; the digital key controller 1, the vehicle body area controller 3 and the cloud communication device 5 are communicated with each other through a public controller local area network, so that the signal transmission speed among all parts of the vehicle-mounted digital key control system and the real-time performance of data communication are improved. The load rate of the whole vehicle is reduced by adopting local area internet communication between the vehicle body area controller 3 and the vehicle-mounted equipment.

Based on the same inventive concept, the embodiment of the present application further provides a vehicle-mounted digital key control method, as described in the following embodiments. Because the principle of the vehicle-mounted digital key control method for solving the problems is similar to that of a vehicle-mounted digital key control system, the implementation of the vehicle-mounted digital key control method can refer to the implementation of the vehicle-mounted digital key control system, and repeated parts are not repeated.
