It should be noted that the words "first", "second" and the like described in this application are only for the convenience of describing the technical solution to distinguish different components, and are not used to limit this application. In order to make the technical solution of the present invention clearer, the present invention is explained through the following embodiments.

[0026] As mentioned above, the English explanations used in this embodiment are shown in Table 1.

[0029] In this embodiment, according to the actual needs of the intelligent domain control, the intelligent domain control system is required to integrate the functions of ADAS, DMS, TBOX, BCM, and GW, that is, the intelligent domain control needs to integrate the functions of the above five parts. The specific functions are remote control, remote diagnosis, remote upgrade, satellite communication, high-precision positioning, active parking, intelligent cruise, fatigue detection, gateway forwarding, vehicle glass lifting, wiper control and other functions, so as to realize the advanced intelligence and networking of the vehicle.

[0030] To this end, this embodiment discloses an intelligent domain control system, such as Figure 1 As shown, the intelligent domain control system of this embodiment includes a first integrated module, a second integrated module, and a third integrated module, wherein:

[0031] The first integrated module includes a first integrated controller and a second integrated controller connected in sequence. The first integrated module is used to implement the integration of ADAS.

[0032] The second integrated module includes a second integrated controller and a third integrated controller connected in sequence. The second integrated module is used to realize the integration of BCM, GW, and TBOX;

[0033] The third integrated module includes a second integrated controller. The third integrated module is used to implement the integration of the DMS.

[0034] Obviously, the first, second, and third integrated modules of this embodiment share the second integrated controller, and the entire system uses only three controllers to improve the system integration. At the same time, this mode of multi-controller sharing can optimize the system structure, reduce costs, and quickly process the communication protocols between multiple controllers. The efficiency of the program is improved, the communication efficiency is optimized, and the work efficiency is improved. In this embodiment, the second integrated controller is mainly responsible for the collection of sensor data such as radar and images, the logical processing of control tasks, the sending and receiving of data, and management, etc. Therefore, the second integrated controller adopts a microcontroller MCU. The microcontroller MCU has the advantages of high integration, strong processing power, and high control efficiency. At the same time, the cost is low, which can meet the needs of high integration and high efficiency of the system. Other control chips can also be selected according to actual conditions during specific implementation.

[0035] At the same time, if Figure 1As shown, the system of this embodiment also includes a power management chip, which is connected to each integrated module and is used to power each integrated module. In this embodiment, the input power of the power management chip is mainly provided by the low-voltage power supply of the vehicle, and other power supplies can also be selected according to actual conditions during specific implementation.

[0036] Specifically, the power management chip of this embodiment includes a DCDC converter, which is connected between the input power supply and each integrated module, and is used to boost or buck the input power supply and output it to each integrated module, thereby providing a suitable operating voltage for the components in each integrated module. The intelligent domain control of this embodiment uses a shared set of power management chips to power the system, which ensures the power supply of the entire system while further simplifying the system structure.

[0037] Combine the following Figure 2 , Figure 3 , Figure 4 Each integrated module of this embodiment is described in detail.

[0038] like Figure 2 As shown, the first integrated module of this embodiment also includes a high-definition camera, an AHD camera, a laser radar and a millimeter-wave radar, wherein:

[0039] The first integrated controller is connected to the HD camera and the AHD camera respectively, and is used to process the images captured by the HD camera and the AHD camera and send them to the second integrated controller. In this embodiment, the first integrated controller can use a chip such as a central processing unit CPU, equipped with an existing trained high-precision image recognition algorithm, so as to recognize headlights, signal lights, speed limit signs, lane lines, curbs, isolation belts, obstacles, dynamic vehicles, pedestrians, etc. according to the images captured by the HD camera and the AHD camera, and send the recognition results to the second integrated controller.

[0040] The second integrated controller is connected to the laser radar and millimeter-wave radar respectively, and the second integrated controller is used to fuse the data of the laser radar, millimeter-wave radar and the data uploaded by the first integrated controller to perform driving path planning and driving decision control. In this embodiment, the second integrated controller also combines radar data during driving path planning and driving decision control, thereby improving the reliability of the ADAS assisted driving function. In the first integrated module of this embodiment, the fusion of image recognition results and radar data enables the vehicle to plan an optimal driving path that is more in line with the actual situation based on real-time road conditions, road boundaries, traffic signs and other factors. At the same time, it enables the vehicle to more accurately judge traffic conditions and its own status, and make accurate acceleration, deceleration, steering and other decisions, thereby improving the operating efficiency of the entire system.

[0041] like Figure 3 As shown, the second integrated module of this embodiment also includes a body electrical control relay, a CAN transceiver, a memory, a vehicle safety and encryption chip, a GPS antenna, and an external communication antenna. The body electrical control relay of this embodiment includes a vehicle air conditioning control relay, a power window control relay, an electric wiper control relay, a vehicle door lock control relay, a light control relay, a rearview mirror folding control relay, etc.

[0042] Among them, the third integrated controller of this embodiment is connected to the memory, vehicle safety and encryption chip, GPS antenna, and external communication antenna respectively, and the third integrated controller is used to establish data security communication between the second integrated controller and external devices, and perform data management at the same time. Based on the above structure, the third integrated controller can remotely communicate data with external devices through the external communication antenna (such as vehicle key signals, etc.); realize the security verification or encrypted transmission of external device data (such as national standard data and enterprise definition protocol, OTA upgrade data) through the vehicle safety and encryption chip to ensure data security during remote communication; realize satellite communication and call functions through the GPS antenna; and realize the caching of communication data through the memory. Therefore, the third integrated controller can obtain the control command of the external device and forward it to the second integrated controller to realize the remote control function of the vehicle (turn on / off the vehicle's low beam headlights, turn on / off the vehicle's air conditioner, turn on / off the vehicle's door locks) or OTA upgrade.

[0043] The second integrated controller of this embodiment is connected to the vehicle body electrical control relay and the CAN transceiver respectively, and the second integrated controller is used to remotely control the opening and closing of the vehicle body electrical control relay according to the data of the external device, and to control the sending and receiving of the CAN message of the whole vehicle. In this embodiment, one end of the CAN transceiver is connected to various electronic control units of the whole vehicle, and one end is connected to the second integrated controller, so that the second integrated controller can realize log management, storage and sending and receiving of vehicle messages. At the same time, according to different remote control commands of the external device (on / off of the vehicle air conditioner, on / off of the electric window, on / off of the electric wiper, on / off of the vehicle door lock, on / off of the light, on / off of the rearview mirror folding), the second integrated controller issues a control command to drive the corresponding control relay to realize the remote control of the vehicle body electrical appliances.

[0044] In this embodiment, the third integrated controller may adopt a microprocessor MPU, which has a more complex instruction set architecture and a unique memory management unit mechanism, and can quickly process and store a large amount of data during communication with external devices, greatly improving communication efficiency, thereby improving the working efficiency of the entire intelligent domain control system.

The infrared lamp and the camera are used to collect the driver's facial image. The infrared lamp and the infrared lamp driver are mounted on the camera, so that the camera can use the information reflected by infrared light to perform imaging, so that the driver's facial features are clearly visible, ensuring that high-quality driver facial images can be collected under various lighting conditions. The image conversion chip is used to process the collected driver's facial image to collect the driver's facial features and send them to the second integrated controller. The second integrated controller analyzes the driver's facial features (for example, analyzing whether the driver has dangerous driving behavior during driving, etc.) and then outputs the driver's state judgment result to remind the driver in time to ensure driving safety.

[0046] In addition, the intelligent domain control system of this embodiment is integrated on a PCB board, which facilitates close coordination between the controllers and improves the working efficiency of the system. At the same time, a PCB board also reduces production and space costs, facilitating large-scale production.

[0047] At the same time, the present application also proposes a vehicle based on the above-mentioned intelligent domain control system, and the vehicle includes the intelligent domain control system.

[0048] In summary, the present invention conducts modular system design according to the functions actually required by the intelligent domain control, and constructs multiple functions of ADAS, DMS, TBOX, BCM, and GW into three integrated modules, which reduces the cost of the whole vehicle and improves work efficiency while ensuring the high efficiency and reliability of multiple intelligent domain control functions. At the same time, the entire system is integrated on a PCB board, and the overall system structure is simple and easy to produce.
