For a traditional automobile, the technology is gradually changed from industry to science, however, for automobile manufacturing, it seems not to be difficult, and how to build the most intelligent automobile is a problem which is difficult to solve. For intelligent cars, a measure of the intelligence height of a product is the ability of the chip algorithm behind it, because the demand for computing power of intelligent cars is much higher than we can see.

At present, automobiles are divided into a power domain, a chassis domain, a cockpit domain, an intelligent driving domain and the like, and all the parts are managed respectively by adopting a domain controller mode. The domain controller contains a database of information such as the user account, password and devices belonging to the domain. When the device is connected to the network, the domain controller first identifies whether the device belongs to the domain, whether a login account used by the user exists, and whether the password is correct. If the above information is incorrect, the domain controller refuses the user to log in from this device. The user can not access the resources protected by the authority on the server when the user can not log in, so that the resources of all parts of the automobile under the management of the domain controller can not be shared, and the situation that the computing power of one domain is greatly surplus and the computing power of the other domain is seriously deficient is generated, so that the internal computing power resources are wasted.

Detailed Description

The embodiments of the present invention are described below with reference to specific embodiments, and other advantages and effects of the present invention will be easily understood by those skilled in the art from the disclosure of the present specification. The invention is capable of other and different embodiments and of being practiced or of being carried out in various ways, and its several details are capable of modification in various respects, all without departing from the spirit and scope of the present invention. It is to be noted that the features in the following embodiments and examples may be combined with each other without conflict.

In the following description, numerous details are set forth to provide a more thorough explanation of embodiments of the present invention, however, it will be apparent to one skilled in the art that embodiments of the present invention may be practiced without these specific details, and in other embodiments, well-known structures and devices are shown in block diagram form, rather than in detail, in order to avoid obscuring embodiments of the present invention.

It should be noted that, in the Domain mode, at least one server is responsible for the authentication of each computer and user connected to the network, and the Domain Controller is called a Domain Controller (DC for short) as a entrance guard of one unit. A Domain Controller (DC) is a storage location of an active directory, and a computer in which the active directory is installed is called a Domain controller. When the active directory is installed for the first time, the computer on which the active directory is installed becomes the domain controller, referred to as "domain control" for short. The domain controller stores directory data and manages the interaction relationship of the user domain, including user login process, authentication, directory search, and the like. One domain may have a plurality of domain controllers. In order to obtain high availability and fault-tolerant capability, only two domain controllers are needed in a domain with a smaller scale, one domain controller is actually used, and the other domain controller is used for fault-tolerant inspection; a larger domain may use multiple domain controllers. The domain controller contains a database of information such as the account of the domain, the password, the computer belonging to the domain, and the like. When a computer is connected to a network, a domain controller firstly identifies whether the computer belongs to the domain, whether a login account used by a user exists or not and whether a password is correct or not. If the information is equally incorrect, the domain controller will refuse the user to log in from the computer. If the user can not log in, the user can not access the resource protected by the authority on the server. The domain controller is composed of an SOC, a power module, an exchange module, a WIFI module and the like. The system comprises a plurality of sensors (a camera module, a millimeter wave radar module, a laser radar module, an ultrasonic radar module, an inertial navigation positioning module), communication (Ethernet, CAN), display (display screen) and other interfaces.

Edge computing means that an open platform integrating network, computing, storage and application core capabilities is adopted on one side close to an object or a data source to provide nearest-end services nearby. The application program is initiated at the edge side, so that a faster network service response is generated, and the basic requirements of the industry in the aspects of real-time business, application intelligence, safety, privacy protection and the like are met. The edge computation is between the physical entity and the industrial connection, or on top of the physical entity. And the cloud computing still can access the historical data of the edge computing.

Cloud computing (cloud computing) is one type of distributed computing, and means that a huge data computing processing program is decomposed into countless small programs through a network "cloud", and then the small programs are processed and analyzed through a system consisting of a plurality of servers to obtain results and are returned to a user. In the early stage of cloud computing, simple distributed computing is adopted, task distribution is solved, and computing results are merged. Thus, cloud computing is also known as grid computing. By the technology, tens of thousands of data can be processed in a short time (several seconds), so that strong network service is achieved.

At present, an automobile is divided into a power domain, a chassis domain, a cockpit domain, an intelligent driving domain and the like, various intelligent functions are realized in a domain controller mode basically adopted in the current intelligent driving field, and an edge calculation method is more adopted in the aspect of calculation. With the development of science and technology, the automatic driving technology is more mature, and the 5G network is rapidly developed, a domain controller for integrating a driving cabin and a cabin adopts a computing mode combining cloud computing and edge computing, and the technology development trend is inevitable.

referring to fig. 1, the system architecture may include an information input and action performing device 101, an information storage unit 102, and a computer device 103. The computer device 103 may be at least one of a desktop Graphics Processing Unit (GPU) computer, a GPU computing cluster, a neural network computer, and the like. The computer device 103 can be used by a person skilled in the art to distribute computing power to System on a Chip (SOC) in a vehicle. According to the actual calculation power required by the vehicle 101 to complete the target action and the calculation power condition of the SOC initially configured by the vehicle, relevant data are stored in the cloud end 102, and the computer device 103 calculates the existing calculation power through the data obtained from the cloud end and distributes the calculation power to the SOCs.

Illustratively, after obtaining the required computing power, the computer device 103 allocates the computing power to 1 SOC for processing, and if the computing power occupancy of a single SOC exceeds a safety threshold, performs task allocation scheduling among a plurality of initial SOCs through task and algorithm allocation, and when the computing power occupancy of all the initial SOCs exceeds the safety threshold, newly adds and starts the SOC. Therefore, task scheduling is firstly carried out between the initial SOCs, and then a new SOC is added, so that the condition that the SOC is insufficient in computational power utilization rate and resource waste is caused is effectively avoided.

It should be noted that the image processing method provided in the embodiment of the present application is generally executed by the computer device 103, and accordingly, the computing power distribution apparatus is generally disposed in the computer device 103.

According to practical experience, the preset calculation power occupancy safety threshold is Q, the SOC first temperature threshold is K1, and the second temperature threshold is K2.

The implementation details of the technical solution of the embodiment of the present application are set forth in detail below:

FIG. 2 is a flow diagram illustrating system-on-chip computational power allocation in accordance with an exemplary embodiment of the present application;

as shown in FIG. 2, the SOC algorithm deployment may be performed by a computer device, which may be computer device 103 shown in FIG. 1. Referring to fig. 2, the SOC calculation power allocation at least includes steps S210 to S240, which are described in detail as follows:

in step S210, a Micro Controller Unit (MCU) is used to acquire a configuration requirement of the vehicle, and determine the number of sensors and display screens connected.

In one embodiment of the present application, the low-profile vehicle model initially profiles driving SOC1 and cabin SOC 3.

In another embodiment of the present application, the high-profile vehicle model initially configures the driving SOC1, the driving SOC2, the cabin SOC3, and the cabin SOC 4.

In step 220, the calculation power occupation of the SOC of the initial configuration of the vehicle is detected, and the required calculation power is distributed to one SOC for execution.

In one embodiment of the present application, the calculation power occupancy of the vehicle's initially configured SOC1 and SOC3 is detected and the required calculation power is distributed to SOC1 for execution.

In another embodiment of the present application, the calculation power occupancy of the vehicle's initially configured SOC1, SOC1, SOC3, and SOC4 is detected, and the required calculation power is distributed to the SOC1 for execution.

In step 230, when the power occupancy of a single SOC exceeds the safety threshold, the required power is distributed among all the initially configured SOCs.

In one embodiment of the present application, when the total required computing power is allocated to SOC1 and the computing power occupancy of SOC1 exceeds the safety threshold, the required computing power is redistributed through tasks and algorithms and allocated to the initially allocated SOC1 and SOC 3.

In another embodiment of the present application, when the total required computing power is allocated to SOC1 and the computing power occupancy of SOC1 exceeds the safety threshold, the required computing power is redistributed by tasks and algorithms to the initially allocated SOC1, SOC2, SOC3 and SOC 4.

In step 240, when the computational power occupancy of all the initial SOCs exceeds the safety threshold, the new SOC is enabled to share tasks.

In one embodiment of the application, required computing power is distributed to the initially configured SOC1 and SOC3 through task and algorithm distribution, and when the computing power occupancy of the SOC1 and the SOC3 both exceed a safety threshold, a new SOC2 is enabled to share tasks. And if the calculation power occupancy of all the SOCs still exceeds the safety threshold after adding 1 SOC for sharing the tasks, continuing to increase the SOCs until the calculation power occupancy of all the SOCs is lower than the safety threshold.

In another embodiment of the present application, the required computing power is allocated to the initially configured SOC1, SCO2, SCO3 and SOC4 through task and algorithm allocation, and when the computing power occupancy of SOC1, SCO2, SCO3 and SOC4 exceeds a safety threshold, the new SOC5 is enabled to share tasks. And if the calculation power occupancy of all the SOCs still exceeds the safety threshold after the tasks are shared by adding 1 SOC, continuing to increase the SOCs until the calculation power occupancy of all the SOCs is lower than the safety threshold.

In one embodiment of the application, according to the actual required computing power, the driving domain needs 1.2 SOC computing power, the cabin domain needs 0.3 SOC computing power, and if the driving domain and the cabin domain are independent of each other and the calculation of the region is completed respectively, the driving domain SOC1 and SOC2 and the cabin domain SOC3 are needed to reach the required computing power. After the domain controllers of the driving domain and the cockpit domain are fused, the boundary between the domain controllers is broken, and the SOC calculation force between the two domains is dynamically distributed, so that the calculation force can be allocated between the SOC1 and the SOC3, and the requirements can be met only by driving the SOC1 and the cockpit SOC 3. Therefore, on one hand, the computational resource waste of the SOC3 is avoided, the resource cost is saved, on the other hand, the whole volume of the domain controller is reduced due to the fact that one SOC is reduced, and the space requirement of vehicle arrangement is reduced.

Fig. 3 is a functional block diagram of a domain controller shown in an exemplary embodiment of the present application.

As shown in fig. 3, the domain controller is composed of an SOC module, an exchange module, an MCU module, a 5G module, a power module, can communication, an ethernet interface, a camera acquisition, a display screen drive, wifi, bluetooth, and other modules. Each SOC employs a core board design, connected through a B2B connector and a backplane. Therefore, each SOC is independent of the other SOC, and can be increased, decreased or changed at any time according to the plugging mode.

In one embodiment of the invention, a safety threshold Q of computational power occupancy is set equal to 80%, at least one redundant SOC expansion board slot is reserved at the beginning of vehicle production. In the actual application process, the calculated power occupancy of SOC1 and SOC3 is detected at low timing, when the calculated power occupancy of a single SOC is higher than 80%, task allocation scheduling is carried out between SOC1 and SOC3 through task and algorithm allocation, all SOC calculated power occupancies are judged to be reduced to be lower than 80%, when the calculated power occupancy of SOC1 and SOC3 reaches 80% of the maximum calculated power of the SOC, a SCO5 is accessed through a high-speed serial computer expansion bus standard (PCI-E for short) interface, the SOC5 is started to share tasks, and if the SOC5 cannot meet the calculated power requirement, the SOC6 is started to calculate the calculated power required by sharing the SCO1, the SCO2 and the SCO3 until the calculated power occupancy of all SOs is lower than 80%.

In another embodiment of the invention, the high-configuration vehicle model is accessed through the SOC1, SOC2, SOC3 and SOC4 modules. If the single calculation force is higher than 80%, the MCU performs task and algorithm distribution, firstly performs task distribution scheduling among 4 SOCs, starts the SOC5 to share the calculation force if the 4 SOC calculation forces all reach the SOC maximum calculation force accounting rate of 80%, and starts the SOC6 to calculate when the SOC5 calculation force can not meet the requirement. The scheme adopts an extensible mode, the computing power of the central computing platform is improved, and the controllers are prevented from being jammed and halted.

In an embodiment of the present invention, as the technology develops and the 5G technology becomes mature, the algorithm of the domain controller will also develop from edge computing to a cloud plan, and at that time, the corresponding SOC is completely in the situation of upgrading or upgrading, or as the technology is upgraded, other upgrading changes occur in the field of automatic driving, and the SOC also has the situation of needing upgrading or upgrading. The SOC can be directly replaced by plugging without great upgrading change of related hardware, so that the cost of a domain controller or the cost of vehicle hardware upgrading is reduced.

And when the domain controller is powered on, detecting the inserting quantity of the SOC modules and starting different configuration programs. And determining the power supply of the SOC according to the access quantity and the calculation power occupancy of the sensors and the display screen.

In one embodiment of the present invention, in the initial configuration of the vehicle, there are provided SOC1 and SOC3 and redundant SOC 5. In the actual working process, the required computing power can meet the requirements only by the SOC1 and the SOC3, and the SOC5 is not actually started, so that the SOC5 is not electrified, the power consumption of a domain controller is reduced, and the endurance mileage of the new energy automobile can be effectively increased.

In an embodiment of the invention, because each SOC is independently supplied with power and is not related to each other, the temperature of each SOC module can be acquired by using the MCU in real time, and a corresponding heat dissipation mode is pertinently adopted according to the difference of the temperature of each SOC, thereby achieving the purpose of fine control.

Fig. 5 is a flow chart illustrating heat dissipation at different temperatures according to an exemplary embodiment of the present application.

As shown in fig. 5, the temperature condition of each SCO module is collected in real time according to the MUC, and when the temperature of the SOC is higher than the ambient temperature, the passive heat dissipation mode is started due to temperature interaction between the SOC and the ambient; when the temperature of the SOC is higher than the ambient temperature and is not lower than a first temperature threshold value K1, starting an active heat dissipation mode and executing primary active heat dissipation; and when the temperature of the SOC is not lower than a second temperature threshold K2, executing secondary active heat dissipation.
