[0058] Specifically, step S11 and step S12 can be executed separately or simultaneously, and the execution order of step S11 and step S12 is not limited herein.

[0059] In one example, as Figure 2 shown, Figure 2Schematic diagram of a central domain controller provided by the present invention. The central domain controller consists of four independent control units: a central gateway control unit, an intelligent driving control unit, a central control unit, and an instrument control unit. Each control unit has an independent power supply and computing unit. Dual-network communication using Ethernet and CAN communication buses is adopted between the central control unit and the central gateway control unit, between the central control unit and the intelligent driving control unit, and between the intelligent driving control unit and the central gateway control unit. The central control unit is connected to the central control screen through LVDS and to the instrument control unit through the SPI interface. The central control unit is connected to external sensors through AHD / LVDS. The instrument control unit is connected to the central gateway control unit through the CAN communication bus and to the instrument through LVDS. The intelligent driving control unit is connected to external sensors through AHD / LVDS / CAN / LIN, etc. The central gateway control unit is connected to external controllers through the body CAN communication bus / chassis CAN communication bus / power CAN communication bus, etc., to achieve data communication between the internal control units of the central domain controller and between the central domain controller and the outside.

[0060] In an embodiment of the present invention, the central domain controller includes multiple control units, and the multiple control units include an instrument control unit, a central control unit, an intelligent driving control unit, and a central gateway control unit. The central control unit receives remote control instructions through a wireless network and wakes up the first control unit to be woken up according to the remote control instructions. The first control unit to be woken up includes at least one of the intelligent driving control unit and the central gateway control unit, so as to achieve on-demand wake-up of the internal control units and communication network of the central domain controller through the wireless network remotely. The central gateway control unit receives an external wake-up request from an external controller through the communication bus and wakes up the second control unit to be woken up according to the external wake-up request. The second control unit to be woken up includes at least one of the instrument control unit, the central control unit, and the intelligent driving control unit, so as to achieve on-demand wake-up of the internal control units and communication network of the central domain controller through the communication bus connection. Furthermore, it realizes the integration of the central domain controller, reduces the number of controllers, wakes up the internal control units and communication network of the central domain controller on demand, and reduces power consumption.

[0061] According to a central domain controller control method provided by the present invention, as Figure 3 shown, step S11 includes:

[0062] S31. The central control unit receives remote control instructions through a wireless network;

[0063] S32. The central control unit determines the control type and the first control unit to be woken up according to the remote control instructions;

[0064] S33. The central control unit sends a first wake-up request to the first control unit to be woken up according to the communication method preset corresponding to the control type.

[0065] S34. The first control unit to be woken up activates a specific type of communication with the central control unit according to the first wake-up request, and the specific type corresponds to the communication method.

[0066] Specifically, taking Figure 2 as an example, after the central control unit of the central domain controller receives a remote control instruction through a wireless network, it parses the remote control instruction to determine the control type and the first control unit to be woken up. In one example, the control type can include three types, namely low data volume requirement, high data volume requirement, and data redundancy requirement.

[0067] The central control unit determines the corresponding preset communication method according to the control type. For example, it is preset that low data volume requirement corresponds to CAN communication bus transmission, high data volume requirement corresponds to Ethernet transmission, and data redundancy requirement is transmitted through both CAN communication bus and Ethernet.

[0068] The central control unit sends a first wake-up request to the first control unit to be woken up according to the determined communication method. If the control type is low data volume requirement, it sends a first wake-up request to the first control unit to be woken up through the CAN communication bus; if the control type is high data volume requirement, it sends a first wake-up request to the first control unit to be woken up through Ethernet; if the control type is data redundancy requirement, it sends a first wake-up request to the first control unit to be woken up through both CAN communication bus and Ethernet.

[0069] If the first control unit to be woken up receives the first wake-up request through the CAN communication bus, it activates the CAN communication bus communication with the central control unit; if the first control unit to be woken up receives the first wake-up request through Ethernet, it activates the Ethernet communication with the central control unit; if the first control unit to be woken up receives the first wake-up request through both the CAN communication bus and Ethernet, it activates the CAN communication bus communication and Ethernet communication with the central control unit.

[0070] In an embodiment of the present invention, the central control unit receives remote control instructions through a wireless network. The central control unit determines the control type and the first control unit to be woken up according to the remote control instructions, and sends a first wake-up request to the first control unit to be woken up according to the preset communication method corresponding to the control type. The first control unit to be woken up activates a specific type of communication with the central control unit according to the first wake-up request. It realizes remotely controlling the central control unit through a wireless network to remotely wake up the control units in the central domain controller on demand and establish communication, reduces the number of controllers to be woken up and wakes up the specified control units on demand, thereby reducing the power consumption of the whole vehicle.

[0071] According to a central domain controller control method provided by the present invention, as Figure 4 shown, step S12 includes:

[0072] S41. The central gateway control unit receives an external wake-up request from an external controller through a communication bus;

[0073] S42. The central gateway control unit wakes up the communication of the external controller according to the external wake-up request, and determines the control type and the second control unit to be woken up according to the external wake-up request;

[0074] S43. The central gateway control unit sends a second wake-up request to the second control unit to be woken up according to the preset communication method corresponding to the control type;

[0075] S44. The second control unit to be woken up activates a specific type of communication with the central gateway control unit according to the second wake-up request, and the specific type corresponds to the communication method.

[0076] Specifically, taking Figure 2 as an example, the central gateway control unit of the central domain controller can receive an external wake-up request from an external controller through a communication bus. The central gateway control unit is connected to the external controller through a body CAN communication bus / a chassis CAN communication bus / a power CAN communication bus, etc. The central gateway control unit receives an external wake-up request sent by the external controller through the CAN communication bus.

[0077] The central gateway control unit wakes up the communication with the external controller according to the external wake-up request. The central gateway control unit analyzes and determines the control type and the second control unit to be woken up according to the external wake-up request. In one example, the control type can include three types, namely low data volume requirement, high data volume requirement, and data redundancy requirement.

[0078] The central gateway control unit sends a second wake-up request to the second to-be-woken control unit according to the determined communication method. If the control type is low data volume requirement, the second wake-up request is sent to the second to-be-woken control unit through the CAN communication bus; if the control type is high data volume requirement, the second wake-up request is sent to the second to-be-woken control unit through Ethernet; if the control type is data redundancy requirement, the second wake-up request is sent to the second to-be-woken control unit through both the CAN communication bus and Ethernet.

[0079] If the second to-be-woken control unit receives the second wake-up request through the CAN communication bus, it activates the CAN communication bus communication with the central gateway control unit; if the second to-be-woken control unit receives the second wake-up request through Ethernet, it activates the Ethernet communication with the central gateway control unit; if the second to-be-woken control unit receives the second wake-up request through both the CAN communication bus and Ethernet, it activates the CAN communication bus communication and Ethernet communication with the central gateway control unit.

[0080] In the embodiment of the present invention, the central gateway control unit receives an external wake-up request from an external controller through a communication bus, wakes up the communication of the external controller according to the external wake-up request, determines the control type and the second to-be-woken control unit according to the external wake-up request, and sends a second wake-up request to the second to-be-woken control unit according to the preset communication method corresponding to the control type. The second to-be-woken control unit activates a specific type of communication with the central gateway control unit according to the second wake-up request. It realizes the establishment of communication for waking up the external controller by the central gateway control unit through the communication bus, and the establishment of communication for waking up the control units in the central domain controller on demand, reduces the number of woken controllers and wakes up the specified control units on demand, thereby reducing the vehicle power consumption.

[0081] According to a central domain controller control method provided by the present invention, as Figure 5 shown, the method further includes:

[0082] S51. The first control unit sends a sleep request to the second control unit; wherein, the first control unit and the second control unit include one of a central control unit, an intelligent driving control unit, and a central gateway control unit, and the first control unit is different from the second control unit;

[0083] S52. The second control unit judges the sleep condition according to the sleep request;

[0084] S53. When the sleep condition judgment passes, the second control unit feeds back a sleep response to the first control unit and closes the communication with the first control unit;

[0085] S54. The first control unit closes the communication with the second control unit according to the sleep response.

[0086] Specifically, in one example, Figure 6 is a schematic diagram of the interaction between the first control unit and the second control unit, Figure 7 is a schematic diagram of the changes in the respective states of the first control unit and the second control unit.

[0087] When the first control unit is in the wake state, it can send a sleep request to the second control unit via Ethernet when there is no communication requirement on its own, and then enter the first waiting sleep state. The second control unit enters the second waiting sleep state when it receives the sleep request in the wake state, and judges the sleep conditions according to the sleep request in the second waiting sleep state. The optional sleep condition can be that there is no communication requirement on its own. If the sleep condition judgment fails, it returns to the wake state. If the sleep condition judgment passes, it sends a sleep response to the first control unit and enters the sleep state, and closes the communication with the first control unit in the sleep state. After the first control unit receives the sleep response from the second control unit in the first waiting sleep state, it enters the sleep state and closes the communication with the second control unit in the sleep state. If the first control unit does not receive the sleep response from the second control unit within the preset time period in the first waiting sleep state, it stops waiting for the sleep state and returns to the wake state.

[0088] In the embodiment of the present invention, the first control unit sends a sleep request to the second control unit. The second control unit judges the sleep conditions according to the sleep request. If the sleep condition judgment passes, the second control unit sends a sleep response to the first control unit and closes the communication with the first control unit. The first control unit closes the communication with the second control unit according to the sleep response. The control unit can quickly enter the sleep state, thereby reducing the power consumption of the domain controller.
