It should be understood that the specific embodiments described herein are only used to explain the present application and are not used to limit the present application.

[0049] It should be noted that the illustrations provided in this embodiment only illustrate the basic concept of the present application in a schematic manner, and therefore the drawings only show components related to the present application rather than being drawn according to the number, shape and size of components in actual implementation.

They do not indicate or imply that the devices or elements referred to must have a specific direction, be constructed and operate in a specific direction, and therefore cannot be understood as limiting the present application. In addition, the terms "first" and "second" are used for descriptive purposes only and cannot be understood as indicating or implying relative importance.

[0052] In the existing automobile communication architecture, each regional gateway and each domain control unit communicate one-to-one through Ethernet. For example, the services of each domain control unit are provided to the vehicle control, cockpit and driving controllers respectively by adopting device abstraction, atomic services and composite services. In addition, the management and maintenance of the domain control units by the regional gateway are also carried out separately. Therefore, in order to meet the needs of signal transmission, it is necessary to develop and upgrade the software of each regional gateway, which increases the R&D cost.

[0053] To this end, the present application proposes an automotive E / E architecture and a signal transmission method, wherein at least one regional gateway is electrically connected to a bidirectional transmission tunnel, and one end of the bidirectional transmission tunnel away from the regional gateway is electrically connected to a central gateway, to obtain the automotive E / E architecture, wherein the bidirectional transmission tunnel corresponds to the regional gateway one-to-one, and when the device in the car needs to perform signal transmission, it can be achieved through the automotive E / E architecture. The present application can be applied to the signal transmission of the vehicle's air conditioner, accessories, body, battery management system, battery pack and other parts.

[0054] For example, the first device is electrically connected to one end of the regional gateway away from the bidirectional transmission tunnel, and the second device is electrically connected to one end of the central gateway away from the bidirectional transmission tunnel, wherein the first device may be an electronic control unit (ECU) of the area corresponding to the regional gateway, and the second device may be a mobile data center (MDC), a vehicle domain controller (VDC), and a cockpit domain controller (CDC). Through the above connection relationship, in the first transmission direction, the first signal to be transmitted of the first device can be received by each regional gateway, and sent to the central gateway through the corresponding bidirectional transmission tunnel, and then the central gateway sends the first signal to be transmitted to the second device. In the second transmission direction, the second signal to be transmitted from each second device can be received by the central gateway, and sent to the regional gateway through the bidirectional transmission tunnel, and then the regional gateway sends the second signal to be transmitted to the first device. The transmission and communication of signals to be transmitted in the vehicle through the above-mentioned automotive E / E architecture only requires software development and upgrading at the central gateway, thereby improving the phenomenon of needing to develop and upgrade software for regional gateways and reducing R&D costs.

[0055] In one embodiment, Figure 1 As shown, an automotive E / E architecture is provided, the architecture comprising:

[0056] at least one regional gateway, one end of the regional gateway being used to be electrically connected to the first device;

[0057] At least one bidirectional transmission tunnel 1, one end of the bidirectional transmission tunnel 1 is electrically connected to the other end of the regional gateway, and the bidirectional transmission tunnel 1 corresponds to the regional gateway one by one;

[0058] A central gateway, one end of the central gateway is electrically connected to the other end of the bidirectional transmission tunnel 1, and the other end of the central gateway is used to be electrically connected to the second device.

[0059] It should be noted that the first device is used to send a first signal to be transmitted in a first transmission direction, and to receive a second signal to be transmitted in a second transmission direction; the second device is used to receive the first signal to be transmitted in the first transmission direction, and to send the second signal to be transmitted in the second transmission direction; and the first transmission direction is used to indicate a direction from the first device to the second device, and the second transmission direction is used to indicate a direction from the second device to the first device.

[0060] As an exemplary description, the first device may be an electronic control unit of the area corresponding to the regional gateway, and the second device may be a mobile data center, a vehicle domain controller, a cockpit domain controller, etc. In addition to being a signal sent by the first device, the first signal to be transmitted may also be other signals in the area corresponding to the regional gateway, and this application does not limit this. The bidirectional transmission tunnel 1 may be an Ethernet tunnel. By making the bidirectional transmission tunnel 1 correspond one-to-one to the regional gateway, the signal to be transmitted can be transmitted through the corresponding bidirectional transmission tunnel 1 during transmission without occupying other bidirectional transmission tunnels 1.

[0061] In the above-mentioned automobile E / E architecture, at least one regional gateway is electrically connected to the bidirectional transmission tunnel 1 respectively, and the end of the bidirectional transmission tunnel 1 away from the regional gateway is electrically connected to the central gateway to obtain the automobile E / E architecture, wherein the bidirectional transmission tunnel 1 corresponds to the regional gateway one-to-one, and when the devices in the automobile need to perform signal transmission, it can be achieved through the automobile E / E architecture. For example, the first device is electrically connected to the end of the regional gateway away from the bidirectional transmission tunnel 1, and the second device is electrically connected to the end of the central gateway away from the bidirectional transmission tunnel 1. Based on this connection relationship, the first device and the second device can transmit signals through the automobile E / E architecture, and only software development and upgrades need to be performed at the central gateway, thereby improving the phenomenon of needing to perform software development and upgrades on each regional gateway and reducing research and development costs.

[0062] Preferably, in one embodiment, Figure 2 As shown, in the first transmission direction, the regional gateway includes:

[0063] A first receiving unit, the first receiving unit is used to receive a first signal to be transmitted from the first device, and identify and assign a label to the first signal to be transmitted to obtain first data to be encapsulated;

[0064] A first encapsulation unit, the first encapsulation unit is electrically connected to the first receiving unit, and the first encapsulation unit is used to encapsulate the first data to be encapsulated to obtain and send a first message frame;

[0065] The central gateway comprises:

[0066] A second decapsulation unit, the second decapsulation unit is used to receive and decapsulate the first message frame to obtain first decapsulation data;

[0067] a second sending unit, the second sending unit being electrically connected to the second decapsulation unit, and the second sending unit being configured to split the first decapsulated data according to the label of the first decapsulated data so as to restore the first decapsulated data to the first signal to be transmitted;

[0068] The first transmission direction is used to indicate a direction from the first device to the second device.

[0069] It should be noted that the regional gateway also includes first interfaces such as CAN, LIN, PWM and IO, one end of the first interface is electrically connected to the first device, and the other end of the first interface is electrically connected to the first receiving unit. The regional gateway also includes a first Ethernet unit, one end of the first Ethernet unit is electrically connected to an end of the first encapsulation unit away from the first receiving unit and an end of the first decapsulation unit away from the first sending unit, and the other end of the first Ethernet unit is electrically connected to an end of the bidirectional transmission tunnel 1 away from the central gateway. The central gateway also includes a second Ethernet unit, one end of the second Ethernet unit is electrically connected to an end of the bidirectional transmission tunnel 1 away from the regional gateway, and the other end of the second Ethernet unit is electrically connected to an end of the second encapsulation unit away from the second receiving unit and an end of the second decapsulation unit away from the second sending unit.

[0070] In the first transmission direction, the regional gateway receives the first signal to be transmitted from the first device through the first interface; and identifies and assigns a label to the first signal to be transmitted through the first receiving unit to obtain first data to be encapsulated; then encapsulates the first data to be encapsulated through the first encapsulation unit to obtain a first message frame; transmits the first message frame to the corresponding bidirectional transmission tunnel 1 through the first Ethernet unit, and transmits it to the second Ethernet unit of the central gateway, and the central gateway deletes the header of the first message frame through the first decapsulation unit to obtain first decapsulated data; splits the first decapsulated data through the first sending unit according to the label in the first decapsulated data, so that the first decapsulated data is restored to the first signal to be transmitted, and the first signal to be transmitted is sent to the second device.

[0071] The regional gateway encapsulates the first signal to be transmitted into a first message frame and transmits it through an Ethernet bidirectional transmission tunnel. The regional gateway will not be aware of the status of the first device. Therefore, if the first device needs to be upgraded or replaced, the regional gateway can also be plug-and-play, thereby reducing the cost of research and development and upgrades.

[0072] As a specific implementation of the above embodiment, Figure 2As shown, in the first transmission direction, the central gateway further includes:

[0075] It should be noted that in order to avoid sending the first signal to be transmitted to each of the second devices and reduce the cost of signal transmission, the first signal to be transmitted needs to be sent to the designated second device. The device abstraction unit determines the corresponding device interface according to the first signal to be transmitted, and the atomic service unit parses the first signal to be transmitted into a first service request, and sends the first service request to the device interface determined by the device abstraction unit, so that the corresponding second device receives the first service request.

[0082] The second transmission direction is used to indicate a direction from the second device to the first device.

[0083] As a specific implementation of the above embodiment, in the second transmission direction, the atomic service unit is further used to receive a second service request from the second device;

[0084] One end of the device abstraction unit is also electrically connected to an end of the second receiving unit away from the second encapsulation unit. The device abstraction unit is also used to encapsulate the second service request into a second signal to be transmitted, and determine the corresponding bidirectional transmission tunnel 1 based on the second signal to be transmitted, so that the second signal to be transmitted is transmitted to the corresponding first device through the corresponding bidirectional transmission tunnel 1.

[0085] In the second transmission direction, the central gateway receives a second service request from the second device through the atomic service unit; the device abstraction unit encapsulates the second service request into a second signal to be transmitted, and determines the corresponding bidirectional transmission tunnel 1; the second receiving unit then identifies and assigns a label to the second signal to be transmitted to obtain second data to be encapsulated; the second encapsulation unit then encapsulates the second data to be encapsulated to obtain a second message frame; the second message frame is transmitted to the bidirectional transmission tunnel 1 determined by the device abstraction unit through the second Ethernet unit, and then transmitted to the first Ethernet unit of the corresponding regional gateway, and the regional gateway deletes the header of the second message frame through the second decapsulation unit to obtain second decapsulated data; the second sending unit splits the second decapsulated data according to the label in the second decapsulated data, so that the second decapsulated data is restored to the second signal to be transmitted, and the second signal to be transmitted is sent to the second device through the interface.
