An example is as follows: the vehicle body electrical equipment located at the front of the vehicle may be classified into one vehicle body electrical equipment group, and the vehicle body electrical equipment located at the rear of the vehicle may be classified into one vehicle body electrical equipment group. As shown in fig. 4, the vehicle body electrical apparatus located at the front of the vehicle includes, but is not limited to: the front door control device comprises a front lamp controller, a top lamp controller, a vehicle body combined switch and a front door controller, wherein the vehicle body combined switch is a device consisting of more than two switches used for controlling light, signals, control electric appliances and the like of an automobile.

Continuing to refer to the above example, as shown in fig. 4, the front lamp controller, the dome lamp controller, the body combination switch and the front door controller are all connected to one CAN bus and then are in communication connection with the body area controller, and the tail lamp controller, the tail door controller, the rear door controller and the door lock controller are all connected to another CAN bus and then are in communication connection with the body area controller.
3. Video domain controller
In this embodiment, the av domain controller may be configured to control the corresponding av entertainment device to perform an operation specified by the av control command in response to receiving the av control command.
For example: if the video and audio control instruction starts the in-vehicle video recording, the video and audio domain controller can control the in-vehicle video recording device to start the camera to record the video in the vehicle. Another example is: if the influence control instruction is to play songs, the video and audio domain controller can control the in-vehicle playing device to play songs specified by the influence control instruction.
In one implementation manner of the embodiment of the invention, the video domain controller is provided with a communication module and a vehicle software remote upgrading module.

The emergency call system can interact with the video domain controller when detecting that the vehicle has a fault/safety accident such as collision, so that personnel in the vehicle can call for help and the like through the video domain controller. When the power battery of the electric vehicle is charged by utilizing wireless charging, the wireless charging can be controlled and displayed through the video domain controller. The audio and video playing and control of the back row entertainment system such as a sound box, a screen and the like can be controlled through the video and audio domain controller. It should be noted that, those skilled in the art can flexibly select or set the fault diagnosis algorithm carried in the video-audio domain controller, and the technical solution after the fault diagnosis algorithm is changed or replaced will fall into the protection scope of the present invention.
The embodiment of the invention divides an electric system into three control domains and sets a domain controller for each domain. When the vehicle needs to be upgraded, the corresponding domain controller can be directly upgraded without adding a large number of electronic control units and designing a more complex network communication line to meet the communication requirement of each electronic control unit, so that the implementation difficulty and cost of vehicle upgrading can be obviously improved. In addition, the whole vehicle domain controller, the vehicle domain controller and the video domain controller are in bidirectional annular communication connection, so that any two adjacent controllers can communicate with the vehicle equipment through a communication medium of the other side, namely, any controller can communicate with the vehicle equipment through the communication medium to perform information interaction. For example: the vehicle body domain controller and the video domain controller can be used as communication media of the whole vehicle domain controller, and the whole vehicle domain controller can be communicated with vehicle equipment through the vehicle body domain controller and can also be communicated with the vehicle equipment through the video domain controller.
In an implementation manner of the embodiment of the present invention, the vehicle devices may be divided into high-voltage electrical devices and low-voltage electrical devices according to voltage levels of the vehicle devices in the vehicle, and further, the whole vehicle domain controller and the vehicle body domain controller are adopted to respectively perform energy consumption control on the high-voltage electrical devices and the low-voltage electrical devices, where the energy consumption control refers to controlling operating states of the vehicle devices according to vehicle states of the vehicle, so as to reduce energy consumption of the vehicle devices to the maximum extent. For example, the vehicle device may be controlled to enter a standby mode when it is detected that the vehicle is stopped, causing the vehicle device to reduce or stop consuming energy such as electric power. Specifically, the whole vehicle domain controller may be configured to perform energy consumption management and control on high-voltage electrical equipment of the vehicle and perform energy consumption management and control on low-voltage electrical equipment of the vehicle when the vehicle domain controller fails, in addition to driving and controlling the vehicle according to the driver operation information and/or the auxiliary driving instruction. The body zone controller may be configured to manage energy consumption of low voltage electrical devices of the vehicle and to simultaneously manage energy consumption of high voltage electrical devices of the vehicle when the full body zone controller fails. According to the description, the whole vehicle domain controller and the vehicle body domain controller can be in redundant control with each other, so that the energy consumption control of the corresponding electrical system can be continuously performed when the whole vehicle domain controller or the vehicle body domain controller fails.
Further, the entire domain controller in this embodiment may be further configured to perform the following operations: and if the communication fault with the high-voltage electrical equipment is detected in the process of carrying out energy consumption control on the high-voltage electrical equipment, the vehicle body domain controller is used as a communication medium to carry out communication interaction with the high-voltage electrical equipment so as to continuously carry out energy consumption control on the high-voltage electrical equipment. Taking an electric vehicle as an example, the high-voltage electrical equipment of the electric vehicle includes but is not limited to: power batteries, inverters, battery management systems, electric drives, and the like. The whole vehicle domain controller CAN communicate with the devices through the CAN bus to control the devices to perform energy consumption management and control. If the communication fault occurs between the whole vehicle domain controller and any one of the devices (for example, the communication interface connected with the high-voltage electrical device arranged on the whole vehicle domain controller fails), the whole vehicle domain controller can continue to perform communication interaction with the high-voltage electrical device through the vehicle body domain controller. The vehicle body area controller CAN also communicate with the high-voltage electrical equipment through the CAN bus, when the whole vehicle area controller and the high-voltage electrical equipment have communication faults, a communication request CAN be sent to the vehicle body area controller, and the vehicle body area controller communicates with the high-voltage electrical equipment specified by the communication request according to the communication request so as to realize communication interaction of the whole vehicle area controller and the high-voltage electrical equipment.
Referring to fig. 4, in an implementation manner according to the embodiment of the present invention, an automatic driving area controller may be further disposed in the vehicle electrical system, and the entire vehicle area controller, the automatic driving area controller, the vehicle body area controller, and the video-audio area controller are connected in a bidirectional ring communication manner through an ethernet. In other words, in the present embodiment, the electric system is divided into four control domains, and one domain controller is provided for each domain. Similar to the foregoing embodiment, in this embodiment, when a vehicle needs to be upgraded, a corresponding domain controller may also be directly upgraded without adding a large number of electronic control units and without designing a more complex network communication line to meet the communication requirement of each electronic control unit, so that the implementation difficulty and cost of vehicle upgrade may be significantly increased. In addition, in the present embodiment, any two adjacent controllers may communicate with each other through a "communication medium" in which the controllers communicate with each other, that is, any controller may communicate with the vehicle device through the "communication medium" to perform information interaction. For example: the vehicle body domain controller and the automatic driving domain controller can be used as communication media of the whole vehicle domain controller, and the whole vehicle domain controller can be communicated with vehicle equipment through the vehicle body domain controller and can also be communicated with the vehicle equipment through the automatic driving domain controller.
In this embodiment the autopilot domain controller may be configured to effect corresponding autopilot control of the vehicle in response to receiving an autopilot command. It should be noted that the autopilot domain controller in this embodiment may be equipped with an autopilot control algorithm that is conventional in the vehicle technology field, and refers to a vehicle control algorithm that is capable of driving the vehicle in place of the driver, and/or completely in place of the driver, for a longer or shorter period of time. And after receiving the automatic driving instruction, calling the automatic driving control algorithm to carry out automatic driving control on the vehicle. The skilled person can flexibly select or set the automatic driving control algorithm carried in the automatic driving domain controller, and the technical scheme after the automatic driving control algorithm is changed or replaced will fall into the protection scope of the present invention. In addition, the automatic driving domain controller can be configured to perform automatic driving control on the vehicle to safely stop the vehicle if a failure of the entire domain controller is detected during the vehicle driving operation performed by the entire domain controller. That is, the automatic driving area controller can detect the working state of the whole area controller when the vehicle performs the vehicle running operation except the automatic driving, and if the whole area controller is detected to be out of order, the vehicle can be controlled to be safely stopped, so that the vehicle is prevented from being in safety accident. Further, in the present embodiment, the automatic driving range controller may assist the entire vehicle range controller in performing the auxiliary driving control on the vehicle, in addition to performing the automatic driving control on the vehicle. Specifically, in the present embodiment, the automatic driving range controller may assist the entire vehicle range controller in performing automatic parking control on the vehicle. The whole vehicle domain controller can be configured to respond to the received automatic parking instruction to perform parking control on the vehicle so as to enable the vehicle to park in the designated parking space, and the automatic driving domain controller can acquire an environment image outside the vehicle and send the environment image to the whole vehicle domain controller when the whole vehicle domain controller performs parking control on the vehicle, so that the whole vehicle domain controller can perform parking control on the vehicle according to the environment image and send the environment image to the audio-visual domain controller for displaying. It should be noted that, in the case that no automatic driving domain controller is provided, the entire domain controller may directly or through another domain controller obtain an environment image outside the vehicle and perform parking control on the vehicle according to the environment image.
In addition to the functional structure of the whole vehicle domain controller in the foregoing embodiment, the whole vehicle domain controller in this embodiment may be configured to perform auxiliary driving control on the vehicle to safely stop the vehicle if a failure of the automatic driving domain controller is detected during automatic driving control of the vehicle by the automatic driving domain controller. That is to say, the whole vehicle domain controller can detect the working state of the automatic driving domain controller when the vehicle is automatically driven, and if the automatic driving domain controller is detected to have a fault, the vehicle can be controlled to safely stop, so that the vehicle is prevented from being out of control in the automatic driving state and a safety accident is prevented. In this embodiment, the body area controller and the video-audio area controller are respectively the same as those in the foregoing embodiments, and for brevity of description, detailed descriptions of specific functional structures of the body area controller and the video-audio area controller are omitted here.
It should be noted that the implementation manner of the vehicle electrical system provided with the automatic driving domain controller according to the embodiment of the present invention may be applied not only to a vehicle with an automatic driving requirement but also to a vehicle without an automatic driving requirement in a short period of time, and at this time, only the automatic driving algorithm is not loaded on the automatic driving domain controller or the automatic driving algorithm loaded on the automatic driving domain controller is controlled to be turned off, and then the automatic driving algorithm is loaded on the automatic driving domain controller or the automatic driving algorithm is loaded on the automatic driving domain controller by an operation such as vehicle upgrade if an automatic driving requirement exists, so that the vehicle is upgraded from the state without the automatic driving function to the state with the automatic driving function.
It should be further noted that, when the vehicle electrical system is applied to a vehicle with no short-term automatic driving demand, the automatic driving area controller has no function or function of starting the automatic driving of the vehicle, but has a function or function of starting the "communication medium". In one embodiment, the entire domain controller may be further configured to perform the following operations: and if the communication fault with the vehicle equipment is detected in the process of carrying out the vehicle running operation by carrying out communication interaction with the vehicle equipment related to vehicle running, the automatic driving area controller is used as a communication medium to carry out communication interaction with the vehicle equipment so as to continuously carry out the vehicle running operation. Referring to fig. 4, vehicle devices associated with vehicle travel may include, but are not limited to: electronic Stability Program (ESP), air suspension, braking system, and Electric Power Steering (EPS). The entire domain controller may communicate with the vehicle devices through the CAN bus to perform a vehicle running operation by controlling the vehicle devices, for example, a braking operation by controlling a braking system. If the whole vehicle domain controller and any one of the vehicle devices have communication faults (for example, a communication interface arranged on the whole vehicle domain controller and connected with the vehicle device has a fault), the whole vehicle domain controller can continue to carry out communication interaction with the vehicle device through the automatic driving domain controller. As shown in fig. 4, the autopilot domain controller may also communicate with the vehicle device through the CAN bus, and when a communication fault occurs between the entire vehicle domain controller and the vehicle device, the autopilot domain controller may send a communication request to the autopilot domain controller, and the autopilot domain controller communicates with the vehicle device specified by the communication request according to the communication request, so as to implement communication interaction between the entire vehicle domain controller and the vehicle device.
