Description

Technical Field

[0001] The present application relates to the field of smart cockpits, and more specifically, to a vehicle-mounted device, a vehicle body and a vehicle. Background Art

[0002] With the rapid development of new energy vehicles, software-defined cars centered on intelligence and networking are gradually entering the historical stage. Current traditional cars and intelligent networked cars only focus on the comfort of seats in the car and provide more advanced intelligent network functions to meet the user experience demands, and the design of the interior space is relatively rigid. Summary of the invention

[0003] The present application provides a vehicle body, vehicle-mounted equipment and a vehicle, which can realize the separation of production and sales of the vehicle body and the vehicle-mounted equipment. Users can flexibly arrange their favorite vehicle-mounted equipment on the vehicle body, which helps to improve the flexibility of interior space design and helps to improve user experience.

[0004] In a first aspect, the present application provides a vehicle body, which includes: a cockpit domain controller, used to receive authentication information sent by an on-board device, and the authentication information is used by a cloud server to authenticate the on-board device; the cockpit domain controller is also used to send the authentication information to the cloud server.

[0005] Based on the above technical solution, the cockpit domain controller in the vehicle body can receive the authentication information sent by the vehicle-mounted device, and then send the authentication information to the cloud server, so that the cloud server can complete the authentication of the vehicle-mounted device. In this way, users can flexibly arrange their favorite vehicle-mounted devices on the vehicle body, and users can use the vehicle-mounted devices after the cloud server successfully authenticates the vehicle-mounted devices, which helps to improve the flexibility of the interior space design and the user experience.

[0006] For example, if the vehicle-mounted equipment is a cockpit device, for the OEM (or vehicle manufacturer), the vehicle may not be installed with cockpit equipment (such as seats, ambient lights, beds, desks, etc.) when it leaves the factory, which can reduce the vehicle's factory cost. Users can flexibly configure cockpit equipment that matches the vehicle body according to the usage scenario. When the user's usage scenario changes, it is also convenient for the user to replace the cockpit equipment to meet the usage needs in different scenarios.

[0007] In combination with the first aspect, in certain implementations of the first aspect, the vehicle body also includes: a first slide rail mechanism, used to connect to a second slide rail mechanism in the vehicle-mounted device, the first slide rail mechanism includes an electrical interface layer, and the electrical interface layer is connected to a power controller; the power controller is used to control the power supply device to supply power to the vehicle-mounted device through the electrical interface layer.

[0008] Based on the above technical solution, the first slide rail mechanism in the vehicle body can be connected to the second slide rail mechanism in the vehicle-mounted device, and the power controller in the vehicle body can control the power supply device to supply power to the vehicle-mounted device through the electrical interface layer in the first slide rail mechanism, thereby realizing the power-on of the vehicle-mounted device. In this way, when the vehicle-mounted device slides to any position in the vehicle body through the second slide rail mechanism, the vehicle body can supply power to the vehicle-mounted device through the electrical interface layer in the first slide rail mechanism, so that the vehicle-mounted device can be powered at different positions, which helps to improve the flexibility of the vehicle-mounted device in powering up, and also helps to improve the flexibility of the layout of the vehicle-mounted device; at the same time, there is no need for the vehicle-mounted device to be connected to the power supply by wire, which reduces the wiring in the vehicle.

[0009] In combination with the first aspect, in certain implementations of the first aspect, the cockpit domain controller is further used to receive an authentication result sent by the cloud server, the authentication result indicating that the authentication of the vehicle-mounted device is successful or failed; the cockpit domain controller is further used to send a first instruction to the power controller when the authentication result indicates an authentication failure, the first instruction instructing the power supply device to stop supplying power to the vehicle-mounted device; the power controller is used to control the power supply device to stop supplying power to the vehicle-mounted device according to the first instruction; or, when the authentication result indicates that the authentication is successful, request the cloud server to control the control drive and / or application corresponding to the vehicle-mounted device.

[0010] Based on the above technical solution, when the authentication result indicates that the authentication failed, the cockpit domain controller can instruct the power controller to stop supplying power to the vehicle-mounted device. In this way, it can prevent the unauthenticated vehicle-mounted device from continuing to draw power from the vehicle body, which helps to save the energy consumption of the vehicle body and also helps to ensure the safety of the vehicle. When the authentication result indicates that the authentication is successful, the cockpit domain controller can request the cloud server to control the corresponding control drive and / or application of the vehicle-mounted device, so as to facilitate the user to control the vehicle-mounted device.

[0011] The above unauthenticated vehicle-mounted devices can also be understood as illegal vehicle-mounted devices, or unverified vehicle-mounted devices.

[0012] The above process of the cloud server authenticating the vehicle-mounted device can also be understood as the cloud server determining whether the vehicle-mounted device is an authenticated device.

[0014] Based on the above technical solution, the power controller can save the association between the vehicle-mounted devices and the power supply interface. In this way, when multiple vehicle-mounted devices are installed on the vehicle body and the cloud server fails to authenticate some of the vehicle-mounted devices, the cockpit domain controller only needs to send the information of the unauthenticated vehicle-mounted devices to the power controller. The power controller can accurately disconnect the power supply of the unauthenticated vehicle-mounted devices based on the association and continue to control the power supply device to supply power to the authenticated vehicle-mounted devices.

[0015] In combination with the first aspect, in certain implementations of the first aspect, the cockpit domain controller is further used to send authentication information to the vehicle-mounted device; the cockpit domain controller is further used to receive the authentication information sent by the vehicle-mounted device when the position of the vehicle-mounted device changes.

In this way, when the position of the vehicle-mounted device changes, the vehicle-mounted device can send the authentication information to the cockpit domain controller, and the cockpit domain controller can determine that the vehicle-mounted device is a successfully authenticated device, and there is no need to authenticate the vehicle-mounted device again.

[0017] In some possible implementations, the cockpit domain controller is used to receive an authentication result indicating successful authentication of the vehicle-mounted device and authentication information corresponding to the vehicle-mounted device sent by a cloud server; and send the authentication information to the vehicle-mounted device.

[0018] Exemplarily, the authentication information may be a public key corresponding to the vehicle-mounted device, and the certification information may be a private key corresponding to the vehicle-mounted device.

[0019] In some possible implementations, the cockpit domain controller is used to generate the authentication information and send the authentication information to the vehicle-mounted device when the authentication result indicates that the authentication of the vehicle-mounted device is successful.

[0020] In combination with the first aspect, in certain implementations of the first aspect, the vehicle body also includes an airbag controller, which is used to send a second instruction to the power controller when a preset condition is met, and the second instruction instructs the power supply device to stop supplying power to the vehicle-mounted equipment; the power controller is used to control the power supply device to stop supplying power to the vehicle-mounted equipment according to the second instruction.

[0021] Based on the above technical solution, the airbag controller can instruct the power controller to stop supplying power to the vehicle-mounted device when the preset conditions are met, thereby avoiding safety hazards caused by continuing to supply power to the vehicle-mounted device in certain emergency situations.

[0022] In some possible implementations, the preset condition includes a condition under which the airbag controller controls the airbag to deploy.

[0023] In combination with the first aspect, in some implementations of the first aspect, the first slide rail mechanism includes an electrical locking mechanism, and the electrical locking mechanism is used to control the connection between the electrical interface layer and the electrical interface of the vehicle-mounted device.

[0025] In a second aspect, a vehicle-mounted device is provided, which includes: a communication interface for sending authentication information to a cockpit domain controller when the vehicle-mounted device is powered on, and the authentication information is used by a cloud server to authenticate the vehicle-mounted device.

[0026] Based on the above technical solution, users can flexibly arrange their favorite in-vehicle devices on the vehicle body. After the cloud server successfully authenticates the in-vehicle device, the user can use the in-vehicle device, which helps to improve the flexibility of the interior space design and help improve the user experience.

[0027] In combination with the second aspect, in certain implementations of the second aspect, the vehicle-mounted device also includes: a second slide rail mechanism for connecting to a first slide rail mechanism of a vehicle body, the first slide rail mechanism includes an electrical interface layer, and the vehicle body supplies power to the vehicle-mounted device through the electrical interface layer.

[0028] Based on the above technical solution, the first slide rail mechanism in the vehicle body can be connected to the second slide rail mechanism in the vehicle-mounted device, and the vehicle body can supply power to the vehicle-mounted device through the electrical interface layer in the first slide rail mechanism, thereby realizing the power-on of the vehicle-mounted device. In this way, when the vehicle-mounted device slides to any position in the vehicle body through the second slide rail mechanism, the vehicle body can supply power to the vehicle-mounted device through the electrical interface layer in the first slide rail mechanism, and the vehicle-mounted device can be powered at different positions, which helps to improve the flexibility of the vehicle-mounted device when powering, and also helps to improve the flexibility of the layout of the vehicle-mounted device; at the same time, there is no need for the vehicle-mounted device to be connected to the power supply by wire, which reduces the wiring in the vehicle.

[0029] In combination with the second aspect, in certain implementations of the second aspect, the electrical interface layer includes multiple electrical interfaces, and the vehicle body supplies power to the vehicle-mounted device through a first electrical interface among the multiple electrical interfaces. The communication interface is also used to send information about the vehicle-mounted device to a power controller of the vehicle body, and the information about the vehicle-mounted device is used by the power controller to establish an association between the first electrical interface and the vehicle-mounted device.

[0030] Based on the above technical solution, by sending the information of the vehicle-mounted device to the power controller through the vehicle-mounted device, the power controller can save the association relationship between the vehicle-mounted device and the power supply interface. In this way, when multiple vehicle-mounted devices are installed on the vehicle body and the cloud server fails to authenticate some of the vehicle-mounted devices, the cockpit domain controller only needs to send the information of the unauthenticated vehicle-mounted devices to the power controller. The power controller can accurately disconnect the power supply of the unauthenticated vehicle-mounted device based on the association relationship and continue to control the power supply device to supply power to the authenticated vehicle-mounted device. In combination with the second aspect, in some implementations of the second aspect, the communication interface is also used to receive the authentication information sent by the cockpit domain controller; the communication interface is also used to send the authentication information to the cockpit domain controller when the position of the vehicle-mounted device changes.

[0032] In combination with the second aspect, in some implementations of the second aspect, the vehicle-mounted device further includes: a memory for storing the authentication information.

[0033] In some possible implementations, the memory is also used to store the authentication information.

[0034] Based on the above technical solution, a memory is set in the vehicle-mounted device, and the memory can store the authentication information. After the vehicle-mounted device is powered on, the authentication information in the memory can be sent to the cockpit domain controller through the communication interface, so that the cockpit domain controller sends the authentication information to the cloud server. The cloud server can complete the authentication of the vehicle-mounted device.

After the vehicle-mounted device 110 is powered on, the vehicle-mounted device 110 can send authentication information to the cockpit domain controller 130 through the communication interface 112. The cockpit domain controller 130 can send the authentication information to the cloud server. If the cloud server fails to authenticate the vehicle-mounted device 110, the cloud server can send the result of the authentication failure to the cockpit domain controller 130. The cockpit domain controller 130 can send an instruction to the power controller 140, which is used to instruct the power controller 140 to control the power supply device 160 to stop supplying power to the vehicle-mounted device 110. After receiving the instruction, the power controller 140 can stop supplying power to the vehicle-mounted device 110.

[0103] If the cloud server successfully authenticates the vehicle-mounted device 110 , the cockpit domain controller 130 may download the control driver and / or application software related to the vehicle-mounted device 110 from the cloud server.

[0104] (2) Disconnect the power supply in an emergency

[0105] For example, the power controller 140 may be connected to the airbag controller 170. The airbag controller 170 may determine whether the condition for the airbag to be deployed is currently met based on one or more of the vehicle's acceleration, roll coefficient, and air pressure data. When the condition is met, the airbag controller 170 may control the airbag to be deployed and send an instruction to the power controller 140, which is used to instruct the power controller 140 to control the power supply device 160 to stop supplying power to the vehicle-mounted device 110. The power controller 140 stops supplying power to the vehicle-mounted device 110 according to the instruction. In this way, the potential safety hazard caused by the power supply device 160 continuing to supply power in the event of an accident can be prevented.

[0106] (3) Current oversaturation power off

[0107] After detecting that the current is oversaturated, the power controller 140 can automatically control the power supply device 160 to stop supplying power to the vehicle-mounted device 110. When the current returns to normal, the cockpit domain controller 130 can send an instruction to the power controller 140, which is used to instruct the power controller 140 to resume supplying power to the vehicle-mounted device 110.

[0108] The vehicle-mounted device 110 in the vehicle 100 can be fixedly connected to the vehicle body steel frame structure. The connection can be made by setting multiple point-shaped structural members (e.g., buckles, hooks, etc.) on the vehicle body, or by connecting through a slide rail mode. The slide rail mode can provide a flexible layout of the vehicle-mounted device, making it convenient for the vehicle-mounted device 110 to draw power more flexibly in different spatial positions.

[0109] Taking the vehicle 100 as a box-type vehicle as an example, Figure 2 A schematic diagram of a slide rail mode provided in an embodiment of the present application is shown.

[0110] like Figure 2 (a) and (b) in the figure respectively show a top view and a front view of the vehicle. The vehicle may include body side rails 1-8, wherein rails 1-4 are ground rails, rails 5 and 6 are side wall rails, and rails 7 and 8 are ceiling rails. The rails 1-8 are fixed to the rigid structure of the vehicle body to form a rigid bracket for fixing the vehicle-mounted equipment 110.

[0111] Optionally, the distance between the slide rails installed on the ground of the vehicle body can be fixed. For example, the distance between slide rail 1 and slide rail 2 is equal to the distance between slide rail 3 and slide rail 4.

[0112] above Figure 2 The number and position of the vehicle body side slide rails are merely illustrative, and are not specifically limited in the present application. For example, slide rails may be installed outside the vehicle body.

[0113] The above slide rails can also be extended to the main driving area, so as to achieve a flexible layout of the vehicle-mounted equipment (for example, seats, interior lights) in the main driving area.

[0114] The above is explained by adding a ground rail, a side rail or a ceiling rail to the vehicle body as an example, and the embodiments of the present application are not limited to this. For example, a rail can also be installed on the outside of the vehicle body. For example, by connecting a lamp to the outer rail of the vehicle body, lighting outside the cabin in a camping scene can be achieved. For another example, by connecting an audio device to the outer rail of the vehicle body, audio data can be played outside the cabin.

[0115] Figure 3 Another schematic diagram of the slide rail mode provided by the embodiment of the present application is shown. The vehicle-mounted equipment can select different slide rails for fixing according to the requirements of width, height, power supply, communication, etc.

[0116] like Figure 3 In the front view shown in (a), taking the vehicle-mounted device 110 as a kitchen device as an example, the slide rail at the bottom of the kitchen device can be connected to the ground slide rail 3 and the ground slide rail 4. Alternatively, the slide rail at the bottom of the kitchen device can be connected to the ground slide rail 3, the ground slide rail 4 and the ceiling slide rail 8.

[0117] like Figure 3 In the front view shown in (b), taking the vehicle-mounted device 110 as a refrigerator as an example, the slide rails at the bottom of the refrigerator can be connected to the ground slide rails 3 and 4.

[0118] like Figure 3 In the front view shown in (c), taking the vehicle-mounted device 110 as a wide piece of furniture (eg, a three-person seat or a bed, etc.), the wide piece of furniture can be connected to the ground slide rails 1-4.

[0119] like Figure 3 In the front view shown in (d), taking the vehicle-mounted equipment 110 as an office equipment (for example, the office equipment includes a table and a lamp) as an example, the slide rails at the bottom of the table can be connected to the ground slide rails 2, 3 and 4, and the slide rails at the top of the lamp can be connected to the ceiling slide rail 8.

[0120] like Figure 3 In the front view shown in (e), taking the vehicle-mounted device 110 as the ambient light 1 and the ambient light 2 as an example, the slide rail on the ambient light 1 can be connected to the side wall slide rail 5 and the slide rail on the ambient light 2 can be connected to the side wall slide rail 6.

[0121] like Figure 3 In the front view shown in (f), taking the vehicle-mounted device as a TV as an example, the slide rails on the top of the TV can be connected to the ceiling slide rails 7 and the ceiling slide rails 8 respectively.

[0122] like Figure 3 In the front view shown in (g), taking the vehicle-mounted equipment 110 as a single seat 1 and a single seat 2 as an example, the slide rail at the bottom of the single seat 1 can be connected to the ground slide rail 3 and the ground slide rail 4, and the slide rail at the bottom of the single seat 2 can be connected to the ground slide rail 1 and the ground slide rail 2.

[0123] Several layout diagrams of the vehicle-mounted device 110 are introduced above. The connection method between the vehicle-mounted device 110 and the vehicle body side slide rail 120 is introduced below in conjunction with an embodiment.

[0124] Method 1: Mechanical connection

[0125] The vehicle-mounted device 110 and the vehicle-side slide rail 120 can be mechanically connected. For example, a slide core is installed on the vehicle-mounted device 110 and a slide shell is installed on the vehicle-side slide rail 120. The movement of the vehicle-mounted device 110 on the vehicle-side slide rail 120 is achieved through the cooperation between the slide shell and the slide core.

[0126] Figure 4 The figure shows a schematic diagram of the connection between the equipment side rail and the vehicle side rail provided in the embodiment of the present application. Figure 4 As shown, the equipment side slide rails and the vehicle body side slide rails can be mechanical slide rails.

[0127] Method 2: Connecting the electrical interface 111 on the vehicle-mounted device 110 to the electrical interface layer 123 on the vehicle-side slide rail 120

[0128] The key to creating a freely configurable in-car space is to be compatible with a variety of in-car devices, including many different types of electrical devices, such as ambient lights, study lights, display screens, refrigerators, and microwave ovens. Therefore, one of the key points is to safely and reliably power in different locations for in-car devices. Currently, in-car devices can be powered by traditional power cords, but this method has great mobility limitations and is limited in quantity, which greatly restricts the development of more and more in-car devices in the future.

[0129] Figure 5 A schematic diagram showing the positional relationship between the electrical interface 111 and the equipment side slide rail 114 provided in an embodiment of the present application is shown.

[0130] like Figure 5 As shown in (a), the electrical interface 111 is provided at the bottom of the vehicle-mounted device 110 (e.g., a seat, a bed, a refrigerator, a kitchen device, etc.). The electrical interface 111 can be electrically connected to the electrical interface layer 123 in the ground rail (e.g., one or more of the ground rails 1-4) through the hole on the equipment side rail 114.

[0131] like Figure 5 As shown in (b), the electrical interface 111 is disposed on the top of the vehicle-mounted device 110 (e.g., a chandelier, a television, etc.). The electrical interface 111 can be electrically connected to the electrical interface layer 123 in the ceiling rail (e.g., one or more of the ceiling rail 7 and the ceiling rail 8) through the hole on the equipment side rail 114.

[0132] like Figure 5 As shown in (c), the electrical interface 111 is provided on the side of the vehicle-mounted device 110 (e.g., the ambient light, kitchen equipment, etc.). The electrical interface 111 can be electrically connected to the electrical interface layer 123 in the side wall rail (e.g., one or more of the side wall rail 5 and the side wall rail 6) through the hole on the device side rail 114.

[0133] For example, Figure 6 A schematic diagram of the structure of the electrical interface 111 provided in an embodiment of the present application is shown.

[0134] like Figure 6 As shown in (a) of FIG. 1 , the electrical interface 111 may include a fixing device 1111, a positive power electrode 1112, a negative power electrode 1113, and an insulating rubber ring 1114. The fixing device 1111 is used to cooperate with the locking mechanism to control the power supply end (including the positive power electrode 1112 and the negative power electrode 1113) to be received or ejected from the interface compartment box ( Figure 6The positive electrode 1112 and the negative electrode 1113 of the power supply, as well as the negative electrode 1113 and the fixing device 1111 are isolated by an insulating rubber ring 1114.

[0135] like Figure 6 As shown in (b), before the power end pops out of the interface compartment box, the locking device locks the fixing device 1111 and compresses the spring.

[0136] like Figure 6 As shown in (c), after the lock is released, the spring pushes the fixing device 1111 to pop out of the power supply end, and the fixing device 1111 stops after it contacts the bottom of the interface compartment box.

[0137] For example, Figure 7 A schematic diagram of the structure of the electrical interface layer 123 provided in an embodiment of the present application is shown.

[0138] like Figure 7 (a) and (b) in the figure respectively show the side view and top view of the electrical interface layer 123. The electrical interface layer 123 includes, from bottom to top, a positive power electrode 1231, an insulating rubber layer 1232, a negative power electrode 1233 and a negative electrode buckle 1234. The positive power electrode 1231 is located at the bottom and includes a plurality of circular grooves (each of which can be understood as a power supply interface). The radius of curvature of the circular groove is Figure 6 The main function of the circular groove is to increase the contact area with the contact of the positive power supply electrode 1112, and to avoid single point contact causing excessive current and thus breakdown of the electrical interface layer 123.

[0139] For example, Figure 8 A schematic diagram is shown of the electrical interface 111 and the electrical interface layer 123 provided in an embodiment of the present application before being in a locked state and after being in a locked state.

[0140] like Figure 8 As shown in (a), this schematic diagram is a side view of the power supply terminal popping out from the interface compartment and in the electrical lock open state. After the power supply terminal pops out from the interface compartment, the negative electrode buckle 1234 is arranged on both sides of the electrical interface layer 123. Even if the vehicle-mounted device 110 is pushed into the appropriate position of the track and the contact of the positive electrode 1112 of the power supply has popped out, the electrical interface layer 123 will not supply power to the vehicle-mounted device.

[0141] like Figure 8As shown in (b) in the figure, this schematic diagram is a side view of the power supply end in an electrically locked state. After the contact of the positive pole 1112 of the power supply pops out, the electrical locking mechanism 122 can control the negative pole buckle 1234 on both sides of the electrical interface layer 123 to move toward the middle. The negative pole buckle 1234 on both sides can hold (or lock) the negative pole 1113 of the power supply, and the electrical interface layer 123 can supply power to the vehicle-mounted device 110. The negative pole buckle 1234 can fix the negative pole 1113 and the positive pole 1112 of the power supply, thereby preventing the vehicle from breaking during vibration.

[0142] The above embodiment introduces the process of powering the vehicle-mounted device 110 through the electrical interface layer 123. The following embodiment introduces the installation and authentication process of the vehicle-mounted device 110. One of the main goals of the embodiment of the present application is to separate the manufacturer of the vehicle-mounted device from the vehicle body, so that more third-party manufacturers can independently participate in the production of standard equipment. Thereby creating a new vehicle-mounted device ecosystem with lower production costs and richer varieties.

[0143] Based on the above scenarios, the vehicle-mounted equipment may be manufactured by a different manufacturer than the vehicle body, and unlike traditional vehicles, the vehicle-mounted equipment may not be certified by the OEM. Since the vehicle-mounted equipment is different from other scenarios and needs to meet higher vehicle-level security requirements, the embodiment of this application provides an authentication method that can perform stricter quality control on the vehicle-mounted equipment, ensure the legitimacy of the vehicle-mounted equipment, and prevent the access of vehicle-mounted equipment that has not been safety certified.

[0144] Fig. 9 The schematic flow chart of the authentication method 900 provided in the embodiment of the present application is shown. The method 900 can be executed by the vehicle-mounted device 110, the cockpit domain controller 130 and the cloud server. The method 900 includes:

[0145] S901 , when the in-vehicle device 110 detects that the power supply device 160 is supplying power to it, the in-vehicle device 110 establishes a connection with the cockpit domain controller 130 .

[0146] Exemplarily, as described in the above embodiment, after the vehicle-mounted device 110 is pushed into the appropriate position of the vehicle-body side slide rail 120 and the mechanical locking mechanism 121 and the electrical locking mechanism 122 of the vehicle-body side slide rail 120 are locked, the power supply device 160 can supply power to the vehicle-mounted device 110 through the electrical interface layer 123. After the vehicle-mounted device 110 detects that the power supply device 160 supplies power to it, the vehicle-mounted device 110 can establish a connection with the cockpit domain controller 130. The connection can be connected through a controller area network (CAN), a local interconnect network (LIN) or Ethernet, or it can also be a wireless connection.

[0147] S902 , the vehicle-mounted device 110 sends authentication information to the cockpit domain controller 130 .

[0148] Optionally, the authentication information may include an identification (ID) of the vehicle-mounted device, an authentication key, and device-related attribute information.

[0149] Exemplarily, the device-related attribute information includes the type of vehicle-mounted device, the type of drive required, the application that controls the vehicle-mounted device, the size of the vehicle-mounted device, etc.

[0150] The on-board equipment provider can be an entire vehicle manufacturer, a third-party manufacturer, or a third-party sales channel. The information of licensed and authenticated on-board equipment can be stored in the database of the cloud server. The on-board equipment provider can produce the on-board equipment according to the specification requirements (for example, the spacing of the side rails of the vehicle body, the control specifications and interfaces included in the on-board equipment). The on-board equipment provider can log in to the on-board equipment on the cloud server and provide device-related attribute information. After the cloud server authenticates the on-board equipment, the encrypted on-board equipment configuration document (for example, a public key or an authentication key) can be provided to the on-board equipment provider. The on-board equipment provider can download the on-board equipment configuration document and write the on-board equipment configuration document into the memory of the on-board equipment before the on-board equipment leaves the factory.

[0151] The body provider can be a vehicle manufacturer or a third-party sales channel. After producing the body, the body provider can log in and save the body information (for example, the position of the slide rails, the distance between the slide rails, the height, width and length of the body, etc.) on the cloud server.

[0152] Before or after purchasing the vehicle body, the user can log in to the cloud server to configure the vehicle equipment in advance. The cloud server can provide users with a visual display interface to guide users to configure the interior space, purchase the vehicle body, or replace the vehicle equipment on the cloud server. At the same time, after the user purchases the vehicle body, the cloud server can assign an ID to the vehicle body. When the user purchases the vehicle equipment and installs it on the vehicle body, the cloud server can bind the ID of the vehicle equipment to the ID of the vehicle body. Users can pick up the configured vehicle at the 4S store, or purchase the vehicle equipment online or offline and install it themselves.

[0153] For example, it is taken that a user completes the purchase of a vehicle body and vehicle-mounted equipment on a personal computer (PC). Fig.10 A schematic diagram of a human machine interface (HMI) provided in an embodiment of the present application is shown.

[0154] like Fig.10 As shown in (a) of FIG. 1 , the display interface includes information about multiple types of vehicles. For example, vehicle body 1, vehicle body 2, and vehicle body 3, as well as the parameters, prices, and information about the side rails of the vehicle bodies corresponding to each type of vehicle body. When it is detected that the user has selected vehicle body 1 and clicked on control 1001, the following information may be displayed: Fig.10 The HMI shown in (b) in FIG.

[0155] like Fig.10 As shown in (b) in FIG. 1 , after detecting that the user has selected vehicle body 1 and clicked control 1001, the PC can send the information of vehicle body 1 to the cloud server. The cloud server can send the information of the vehicle-mounted equipment that matches vehicle body 1 to the PC based on the information of vehicle body 1. For example, the display interface of the PC can display the classification information of the vehicle-mounted equipment that matches vehicle body 1 (for example, office equipment, lamps, televisions, furniture equipment, etc.). When detecting that the user clicks control 1002 corresponding to the furniture equipment, the PC can display the following information: Fig.10 The HMI shown in (c) in FIG.

[0156] like Fig.10 As shown in (c) of FIG. 1 , when the user selects the control 1002 corresponding to the furniture device, the PC can request the information of the furniture device from the cloud server. The cloud server can send the PC information of multiple furniture devices matching the vehicle body 1, such as bed 1 information, bed 2 information, seat 1 information, seat 2 information, etc. When the user is detected to move seat 1 to the vehicle body display area 1003, the PC can display the following information: Fig.10 The HMI shown in (d) in FIG.

[0157] like Fig.10As shown in (d) in FIG. 1 , when it is detected that the user moves the seat 1 to the vehicle body display area 1003 , a suitable installation position of the seat 1 can be automatically displayed. For example, the seat 1 can be installed on the floor slide rail 1 and the floor slide rail 2 .

[0158] Optionally, the user can also view the three-dimensional effect diagram when the seat 1 is configured inside the vehicle body 1 by selecting the in-cabin perspective.

[0159] Optionally, the PC may also send information about the vehicle body 1 and the seat 1 to the cloud server. The cloud server may send layout suggestions for the vehicle-mounted devices in the remaining space of the vehicle body 1 to the PC based on the information about the vehicle body 1 and the seat 1. Exemplarily, when it is detected that the user moves the seat 1 to the vehicle body display area 1003, the PC may also display layout suggestions for the remaining space, for example, suggesting that the user layout vehicle-mounted devices such as a TV and an ambient light in the remaining space.

[0160] Optionally, when it is detected that the user has selected the vehicle body 1 and clicked the control 1001 , the PC may also display the spatial layout of the vehicle-mounted equipment suggested by the vehicle body 1 .

[0161] Fig.11 Another HMI provided by an embodiment of the present application is shown.

[0162] After detecting that the user has selected the vehicle body 1 and clicked the control 1001, the PC can send the information of the vehicle body 1 to the cloud server. The cloud server can send the space layout 1 and space layout 2 of the vehicle-mounted equipment of the vehicle body 1 to the PC based on the information of the vehicle body 1. Among them, the space layout 1 includes a single seat, a desk, a chandelier and a bed. The space layout 2 includes a TV, a three-person seat and a refrigerator. For example, after detecting that the user has selected the space layout 1, the PC can send the information of the space layout 1 to the cloud server. The cloud server can send the information of the single seat 1, the single seat 2, the desk 1, the desk 2, the chandelier 1, the chandelier 2, the bed 1 and the bed 2 to the PC based on the space layout 1. So that the user can choose the vehicle-mounted equipment he likes from it.

[0163] Optionally, the PC can also prompt the user to input a desired layout scene (e.g., outing, office, in-cabin KTV), thereby controlling the display screen to display different space layouts according to the user's desired layout scene.

[0164] The above is explained by taking the purchase of the vehicle body and the vehicle-mounted equipment through the PC terminal as an example, and the embodiment of the present application is not limited to this. For example, the purchase can also be made through other terminals (for example, mobile phones, sales terminals in 4S stores).

[0165] The above description is based on an example of a PC requesting information about vehicle-mounted devices from a cloud server, and the present application embodiment is not limited thereto. For example, the PC may store information about vehicle-mounted devices produced by different vehicle-mounted device providers related to the vehicle body 1 .

[0166] The above HMI display may occur before the user purchases the vehicle body and the vehicle-mounted device, or after the user purchases the vehicle body and before purchasing the vehicle-mounted device. In one embodiment, after the user purchases the vehicle body, the vehicle body ID may be logged in on the PC. The PC may control the display screen to display the information of the vehicle-mounted device matching the vehicle body according to the vehicle body ID input by the user.

[0167] S903, the cockpit domain controller 130 sends the authentication information to the cloud server.

[0168] S904, the cloud server authenticates the vehicle-mounted device 110 according to the authentication information.

[0169] The cloud server authenticating the vehicle-mounted device 110 can also be understood as the cloud server determining whether the vehicle-mounted device 110 is an authenticated device.

[0170] Optionally, the cloud server may authenticate the vehicle-mounted device 110 according to an authentication key or a public key in the authentication information.

[0171] S905, the cloud server sends the authentication result to the cockpit domain controller 130.

[0172] S906: The cockpit domain controller 130 determines whether the authentication of the vehicle-mounted device 110 is successful based on the authentication result.

[0173] If the authentication is successful, the cockpit domain controller 130 may execute S907; otherwise, execute S908.

[0174] S907, if the authentication result indicates that the authentication is successful (or, the authentication result indicates that the vehicle-mounted device 110 is an unauthenticated device), the cockpit domain controller 130 can send an instruction to the power controller 140, which is used to instruct the power controller 140 to control the power supply device 160 to stop supplying power to the vehicle-mounted device 110.

[0175] Correspondingly, after receiving the instruction, the power controller 140 can control the power supply device 160 to stop supplying power to the vehicle-mounted device 110 .

[0176] The above electrical interface layer 123 may include multiple power supply interfaces, and the electrical interface 111 may be connected to different power supply interfaces when the vehicle-mounted device 110 moves to different positions.

[0177] Exemplarily, taking the case where the vehicle-mounted device 110 is a single seat, when the single seat is connected to the vehicle body side slide rail 120 and the power controller 140 supplies power to the single seat through the power supply interface 1 in the power supply interface layer 123, the single seat can send the ID of the single seat to the power controller 140. The power controller 140 can establish an association relationship between the ID of the single seat and the power supply interface 1. When the cloud server fails to authenticate the single seat, the cockpit domain controller 130 can send the ID of the single seat and indication information to the power controller 140, and the indication information is used to instruct to stop supplying power to the single seat. The power controller 140 can stop supplying power to the single seat through the power supply interface 1 based on the previously saved association relationship and the ID of the single seat.

[0178] The above single seat can send the ID of the single seat to the power controller 140 through the communication interface, or the ID of the single seat can be sent to the power controller through the power supply interface 1. When multiple vehicle-mounted devices are installed on the vehicle body at the same time, their corresponding IDs are sent to the power controller through different power supply interfaces, so that the power controller 140 can save the association between different vehicle-mounted devices and different power supply interfaces, which is convenient for the power controller 140 to accurately disconnect the power of unauthenticated devices.

[0179] When the power controller 140 establishes the association between the ID of the single seat and the power supply interface 1, the association can also be sent to the cockpit domain controller 130. When the cloud server fails to authenticate the single seat, the cockpit domain controller 130 can send an indication message to the power controller 140 based on the association, and the indication message is used to instruct to stop supplying power through the power supply interface 1. The power controller 140 can control the power supply device to stop supplying power to the single seat through the power supply interface 1 based on the indication message.

[0180] Exemplarily, taking the case where the vehicle-mounted device 110 is a single seat, when the single seat is connected to the vehicle body side slide rail 120 and the power controller 140 supplies power to the single seat through the power supply interface 1 in the power supply interface layer 123, the power controller 140 can send information about the power supply interface 1 to the single seat. The single seat can send the association between the single seat and the power supply interface 1 to the cockpit domain controller. When the cloud server fails to authenticate the single seat, the cockpit domain controller 130 can send an indication message to the power controller 140, and the indication message is used to instruct to stop supplying power through the power supply interface 1. The power controller 140 can stop supplying power to the single seat through the power supply interface 1 according to the indication message.

[0181] S908, if the authentication result indicates that the authentication is successful (or the vehicle-mounted device is an authenticated device), the cockpit domain controller 130 may request the cloud server to provide control drivers and / or application software related to the vehicle-mounted device 110.

[0182] Fig.12 A schematic block diagram of a vehicle body 1200 provided in an embodiment of the present application is shown. The vehicle body 1200 includes: a cockpit domain controller 130, which is used to receive authentication information sent by the vehicle-mounted device 110, and the authentication information is used by the cloud server to authenticate the vehicle-mounted device; the cockpit domain controller 130 is also used to send the authentication information to the cloud server.

[0183] Exemplarily, the vehicle-mounted device 110 may send authentication information to the cockpit domain controller 130. The cockpit domain controller 130 may send the authentication information to the cloud server.

[0184] In the embodiment of the present application, the vehicle-mounted device 110 may send the authentication information to the cockpit domain controller 130 before connecting to the vehicle body. For example, the vehicle-mounted device 110 may send the authentication information to the cockpit domain controller 130 after connecting to other power sources other than the vehicle body 1200. Alternatively, the vehicle-mounted device 110 may also send the authentication information to the cockpit domain controller 130 after connecting to the vehicle body.

[0185] Optionally, the vehicle body 1200 also includes: a first slide rail mechanism, used to connect to a second slide rail mechanism in the vehicle-mounted equipment, the first slide rail mechanism includes an electrical interface layer 123, and the electrical interface layer 123 is connected to the power controller 140; the power controller 140 is used to control the power supply device 160 to supply power to the vehicle-mounted equipment 110 through the electrical interface layer 123.

[0186] Exemplarily, the first slide rail mechanism may be the vehicle body side slide rail 120 .

[0187] Exemplarily, the second slide rail mechanism may be the equipment side slide rail 114 mentioned above.

[0207] Fig.13 1300 is a schematic flow chart of a control method 1300 provided in an embodiment of the present application. The control method may be implemented by a terminal device (eg, Fig.10 The control method 1300 may be executed by a laptop computer or a sales terminal in a car sales service 4S store, or the control method may be executed by a processor, chip or circuit of a terminal device. The following takes the control method 1300 executed by a terminal device as an example, and the method 1300 includes:

[0209] Optionally, the terminal device obtains the information of the first vehicle body, including: the terminal device controls a display device to display information of multiple vehicle bodies, the multiple vehicle bodies including the first vehicle body; in response to detecting user input for the first vehicle body, the information of the first vehicle body is obtained.

[0210] For example, Fig.10 As shown in (a) in FIG. 1 , when it is detected that the user selects the vehicle body 1 and clicks the control 1001 , the terminal device can obtain the information of the vehicle body 1 selected by the user.

[0211] Exemplarily, the information of the vehicle body 1 includes the type of the vehicle body 1. For example, the vehicle manufacturer or the main engine manufacturer can produce different types of vehicle bodies, and the terminal device can display the different types of vehicle bodies through a display device. When the terminal device detects the user's input of selecting the vehicle body 1, it can send the type of the vehicle body 1 to the cloud server.

[0212] Optionally, the terminal device acquires the information of the first vehicle body, including: the terminal device controls the display device to display a first interface, the first interface being an input interface for the identification of the vehicle body that the user has purchased; the terminal device acquires the information of the first vehicle body in response to detecting that the user inputs the identification of the first vehicle body. Exemplarily, the identification of the first vehicle body may be an identification assigned to the user by the cloud server after the user purchases the vehicle body. Alternatively, the identification of the first vehicle body may be a vehicle identification number.

[0213] When the cloud server determines that the user has purchased the vehicle body 1, a vehicle body ID of the vehicle body 1 can be assigned to the user account. When the cloud server determines that the user has purchased a single seat matching the vehicle body 1, an ID can be assigned to the single seat, and the ID of the vehicle body 1 can be bound to the ID of the single seat.

[0214] Optionally, the terminal device controls the display device to display one or more vehicle-mounted devices according to the information of the first vehicle body, including: the terminal device sends the information of the first vehicle body to the cloud server; and receives the information of the one or more vehicle-mounted devices sent by the cloud server.

[0215] The cloud server can store information about the vehicle body and information about the vehicle-mounted equipment that matches the vehicle body. The matching of the vehicle-mounted equipment with the vehicle body can be understood as matching the parameters of the equipment-side slide rails of the vehicle-mounted equipment with the parameters of the vehicle-side slide rails. When the cloud server receives the information about the first vehicle body (for example, the type of the first vehicle body), it can determine the parameters of the slide rails in the vehicle body selected by the user (for example, the distance between the ground slide rails, the distance between the ceiling slide rails), and thus can send information about the vehicle-mounted equipment that matches the vehicle body to the terminal device.

[0216] S1320, the terminal device controls the display device to display one or more vehicle-mounted devices according to the information of the first vehicle body, wherein the slide rail of each of the one or more vehicle-mounted devices matches the slide rail of the first vehicle body.

[0218] For example, Fig.10As shown in (b) of FIG. 1 , when the terminal device detects that the user has selected an operation of the vehicle body 1, the display screen can be controlled to display information of different types of vehicle-mounted equipment (for example, furniture equipment, television, lamps, and office equipment). When the user selects an input of a furniture equipment, information of multiple furniture equipment can be displayed, such as Fig.10 Seat 1, seat 2, bed 1 and bed 2 shown in (c) .

[0219] The terminal device can control the display device to display the information of one or more vehicle-mounted devices based on the acquired information of the first vehicle body, thereby facilitating the user to select the vehicle-mounted equipment that he or she wishes to arrange on the first vehicle body. This helps to improve the user's flexibility in purchasing vehicle bodies and vehicle-mounted equipment, and also helps to improve the user's sense of participation in the design of the spatial layout of the vehicle-mounted equipment.

[0220] Optionally, the method 1300 also includes: the terminal device obtains the user's input to unbind the first vehicle-mounted device and the first vehicle body, and sends a request message to the cloud server, wherein the request message is used to request the cloud server to delete the association between the first vehicle-mounted device and the first vehicle body, or the request message is used to request the cloud server to unbind the first vehicle-mounted device and the first vehicle body.

[0221] In this way, when the user wants to sell the first vehicle-mounted device, the user can perform an unbinding input through the terminal device. The terminal device can send a request message to the cloud server to unbind the first vehicle body and the first vehicle-mounted device. When the user sells the first vehicle-mounted device to other users, the other users can install the first vehicle-mounted device on another vehicle body and use the first vehicle-mounted device on the other vehicle body.

The cloud server may store the correspondence between the type of the vehicle body 1 and the relevant parameters of the vehicle body 1 (for example, the number, installation position, spacing, etc. of the slide rails on the vehicle body 1).

[0225] S1420, the cloud server sends information of one or more vehicle-mounted devices to the terminal device based on the information of the first vehicle body, and the slide rail of each of the one or more vehicle-mounted devices matches the slide rail of the first vehicle body.

[0227] Exemplarily, the ID and authentication information of the vehicle-mounted device are stored in the memory of the vehicle-mounted device. After the vehicle-mounted device is powered on, the vehicle-mounted device can send the ID and authentication information of the vehicle-mounted device to the cockpit domain controller, and the cockpit domain controller can send the ID and the authentication information of the vehicle-mounted device to the cloud server. When the cloud server successfully authenticates the cockpit device, it can establish a binding relationship between the cockpit device ID and the vehicle body ID and send an authentication result of the successful authentication of the cockpit device to the cockpit domain controller.

[0228] Optionally, the method 1400 also includes: the cloud server receives a request message sent by the terminal device, the request message is used to request the cloud server to delete the association between the first vehicle-mounted device and the first vehicle body, or the request message is used to request the cloud server to unbind the first vehicle-mounted device and the first vehicle body; the cloud server deletes the association between the first vehicle-mounted device and the first vehicle body according to the request message, or unbinds the binding relationship between the first vehicle-mounted device and the first vehicle body.

The cloud server may complete the authentication of the drive motor and send the authentication result to the autonomous driving domain controller. When the authentication result indicates that the authentication is successful, the autonomous driving domain controller may request the cloud server to control the drive or application of the drive motor. When the authentication result indicates that the authentication fails, the autonomous driving domain controller may disconnect the communication with the drive motor and instruct the power controller to stop supplying power to the drive motor.

[0231] For example, Fig.16Another schematic block diagram of a vehicle 100 provided in an embodiment of the present application is shown. The vehicle-mounted device may be a vehicle-mounted battery, and the vehicle-mounted battery may send its corresponding authentication information to a battery control unit (BCU) in the vehicle body, so that the BCU sends the authentication information to a cloud server. The cloud server may complete the authentication of the battery and send the authentication result to the BCU. When the authentication result indicates that the authentication is successful, the BCU may request the cloud server to control the drive or application of the battery.
