This application provides a data storage method, which relates to the technical field of intelligent driving. In order to describe the solution of this application more clearly, some knowledge related to intelligent driving is first introduced below.

The current vehicle control is divided into five major areas according to functions: power domain, chassis domain, cockpit domain, autonomous driving domain and body domain. Each area launches a corresponding domain controller, and finally through the controller area network, Communication methods such as CAN) or local interconnect network (LIN) are connected to the main line or even hosted in the cloud, thereby realizing the interaction of vehicle information data.

Intelligent driving domain controller: An intelligent driving car contains four core subsystems: sensors, computing platforms, actuators, and application algorithms. The intelligent driving domain controller is positioned as a computing platform and is responsible for realizing intelligent driving panoramic perception, map and sensor fusion. The automobile "brain" with functions such as positioning, decision-making, planning, and control is suitable for passenger cars (such as congestion following, high-speed cruising, automatic valet parking), commercial vehicles (such as port freight, trunk logistics) and work vehicles (such as Such as mining trucks, cleaning vehicles, unmanned delivery) and other application scenarios.

Smart cockpit domain controller: The smart cockpit domain controller needs to have excellent processing performance to support cockpit domain applications, such as voice recognition, gesture recognition, etc.; provide excellent display performance support, while supporting virtualization technology and supporting multiple cores The screen display meets the display needs of various sizes of instrument screens and central control screens, and isolates applications with different security levels. It also provides external and internal communication capabilities and provides a stable and high-speed communication network to easily cope with various high-speed Network requirements for bandwidth applications.

Vehicle domain controller: With the development of the vehicle, there are more and more body controllers. In order to reduce the cost of the controller and reduce the weight of the vehicle, integration requires all functional devices, from the front part of the vehicle to the middle part of the vehicle and Parts at the rear of the car, such as the rear brake lights, rear position lights, tailgate locks, and even the double struts, are all connected to a master controller. The vehicle domain controller has gradually transitioned from a decentralized function combination to a large controller integrating basic drives, key functions, lights, doors, windows, etc. of all body electronics.

Power domain controller: It is an intelligent powertrain management unit that uses CAN and other communication methods to manage the transmission, manage the battery, monitor the alternator adjustment. Its advantage lies in calculating and allocating torque to a variety of power system units (such as internal combustion engines, electric motors/generators, batteries, gearboxes, etc.), and achieving carbon dioxide emission reductions through predictive driving strategies.

Chassis domain controller: The chassis domain is related to vehicle driving and consists of transmission system, driving system, steering system and braking system. With the development of automobile intelligence, among the three core systems of perception and identification, decision-making and planning, and control execution of smart cars, the control execution end mainly includes drive control, steering control, braking control, etc., which requires wire-controlled transformation of the chassis of traditional cars. suitable for autonomous driving.

Vehicle-mounted gateway: As the core control device of the vehicle network system, the vehicle-mounted gateway is responsible for coordinating protocol conversion, data exchange, fault diagnosis, etc. between CAN bus networks and other data networks with different structures and characteristics. The vehicle-mounted gateway is used to provide network compatibility functions such as protocol conversion and data exchange when collecting networks with different architectures or protocols. The vehicle-mounted gateway can be understood as a connector between networks, a protocol converter, and a data converter. Translator. Vehicle-mounted gateways can be used for both wide-area interconnection and local-area interconnection, serving as a computer system or device responsible for conversion between two systems that use different protocols, data or languages, or even two completely different architectures.

The embodiments of the present application will be described below with reference to the drawings in the embodiments of the present application.

Please refer to FIG. 1 , which is an architectural schematic diagram of a vehicle system provided by an embodiment of the present application.

As shown in Figure 1, the vehicle system includes multiple ECUs, such as vehicle gateways (vehicle gateway 1, vehicle gateway 2, vehicle gateway 3, vehicle gateway 4, etc.), intelligent driving domain controller, intelligent cockpit domain controller, Vehicle domain controller and other ECUs. Among them, the above-mentioned ECUs are connected to each other through communication methods such as CAN or LIN or Ethernet port, thereby realizing the interaction of vehicle information data.

It should be understood that the modules/components/architecture of the vehicle system shown in Figure 1 above are divided based on logical functions. In practical applications, the function of one module/component can also be implemented by multiple modules/components, or multiple The functions of each module/component are implemented by one module/component. The vehicle system shown in the embodiment of this application is only a possible architecture implementation, and this application should not be limited by this.

Generally, most ECUs have their own storage units, such as non-volatile memory, embedded multimedia cards, etc., in order to store key information. For example, the vehicle-mounted gateway will record key information about hardware errors in the storage unit for subsequent query and analysis.

Storage units will have service life limits. For example, if the number of erase times exceeds the limit, abnormal power failure, etc., bad blocks will be generated, thus affecting the normal use of the storage unit. At present, for ECUs with high bad block rates in storage units, the ECU is usually replaced as a whole to ensure the normal use of the storage function. However, the above method may lead to data loss, poor data storage stability, and high storage costs.

In view of the technical problems of poor data storage stability and high storage cost in the above storage method, this application provides a new data storage architecture, and accordingly proposes a new data storage method based on this architecture, using Multiple network elements collaborate to complete data storage, which can improve the stability of data storage, improve the overall storage availability of network elements, and reduce storage costs.

The above-mentioned vehicle-mounted gateway 4 and the intelligent cockpit domain controller communicate through CAN, LIN or Ethernet port. Connect to each other to realize the exchange of information data between the vehicle gateway 4 and the smart cockpit domain controller.

Among them, the smart cockpit domain controller mainly includes a storage read-write interface module, a local storage status management module, a storage policy decision-making module, and a global storage status management module.

The local storage status management module is used to obtain bad block information, erasure times, alarm information and other storage-related information of the storage unit in the smart cockpit domain controller, and generate the storage status of the smart cockpit domain controller based on this information. The generated storage status of the smart cockpit domain controller may include but is not limited to: the size of available storage resources of the storage unit in the smart cockpit domain controller, or the size of storage resource utilization, and so on. The storage status of the smart cockpit domain controller represents the storage performance of the storage unit in the smart cockpit domain controller. The smart cockpit domain controller can decide whether to store data in the storage unit of the smart cockpit domain controller based on the storage status. The storage status of the smart cockpit domain controller can also be sent to the remote network element (such as the vehicle gateway 4) through the storage read-write interface module, which is used by the remote network element to decide whether to store the data to be stored in the remote network element to the smart cockpit. Within the storage unit of the domain controller.

The global storage status management module is used to obtain the storage status of remote network elements from interconnected remote network elements (such as vehicle gateway 4) through communication methods such as CAN, LIN or Ethernet, and generate global storage status. The generated global storage status may include but is not limited to: the size of available storage resources of the storage units of each remote network element globally, or the size of storage resource utilization, and so on. The overall situation in the embodiment of this application includes but is not limited to remote network elements that can be connected to the smart cockpit domain controller through communication methods such as CAN, LIN, or Ethernet ports. The global storage status represents the storage performance of the storage units in each remote network element globally. The smart cockpit domain controller can decide whether to store data in the storage units of each remote network element globally based on the global storage status.
