[0033] To make the purpose, technical scheme and advantages of the embodiments of the present application clearer, the technical scheme in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are only a part of the embodiments of the present application, rather than all of the embodiments. The components of the embodiments of the present application usually described and shown in the drawings here can be arranged and designed in various different configurations. Therefore, the following detailed description of the embodiments of the present application provided in the drawings is not intended to limit the scope of the application claimed for protection, but merely represents the selected embodiments of the present application. Based on the embodiments of the present application, each other embodiment obtained by those skilled in the art without making creative work belongs to the scope of protection of the present application.

[0034] According to research, the traditional automobile architecture is composed of distributed, independent functional controllers, and the corresponding traditional car factory shock absorber development is currently based on object-oriented form. Specifically, the shock absorber controller receives the signals forwarded and received by the gateway to implement the writing of internal functional logic software.

[0035] However, in this way, since the related receiving signals under bus communication are relatively fixed, the support for subsequent function upgrades and expansions is poor, and it is impossible to achieve software and hardware decoupling, and there are many changes. For example, when the shock absorber control program is updated, all controller software involving the signal needs to be updated. Therefore, it leads to a long development cycle and high development costs.

[0036] Based on this, an embodiment of the present application provides a vehicle shock absorption control system based on SOA services to improve the scalability of the shock absorption control function and reduce controller hardware changes during software iterations, thereby improving development efficiency and reducing development costs.

[0037] See also Figure 1 , Figure 1 A schematic diagram of the structure of a vehicle shock absorption control system based on SOA services provided in an embodiment of the present application. Among them, SOA services (Service-Oriented Architecture) refer to a software design architecture that modularizes different functions of an application and interacts through service interfaces. These services can be independently developed, deployed and maintained, thereby improving the flexibility, scalability and reusability of the system.

[0038] like Figure 1 As shown in , the vehicle shock absorption control system provided by the embodiment of the present application includes: a shock absorption control main module 100, a power main module 200, a brake service extraction main module 300, a steering service extraction main module 400, a shock absorber solenoid valve service extraction module 500 and a vehicle height sensor service extraction module 600. The vehicle shock absorption control system provided by the embodiment of the present application adopts the overall architecture of the regional controller and the central computing platform, and this deployment method can realize flexible changes in software.

[0039] Here, the shock absorption control main module is used to obtain power information by subscribing to the power service provided by the power main module; to obtain braking information by subscribing to the braking service of the braking service extraction main module; to obtain steering information by subscribing to the steering service of the steering service extraction main module; to obtain shock absorber solenoid valve status information by subscribing to the shock absorber solenoid valve status service of the shock absorber solenoid valve service extraction module; and to obtain vehicle height information by subscribing to the vehicle height status service of the vehicle height sensor service extraction module.

[0040] Furthermore, the power services provided by the power main module include: high-voltage power-on status service, gear information service and vehicle readiness status service; the power information includes: high-voltage power-on status, gear information and vehicle readiness status.

[0041] Among them, the high-voltage power-on state refers to the state in which the high-voltage battery system is activated and starts to supply power during the startup process of the car; the gear information refers to the current gear state of the vehicle's transmission, usually including parking gear (P), reverse gear (R), neutral gear (N), driving gear (D), etc.; the vehicle ready state (vehicle Ready state) refers to the state in which all key systems (such as engine, brakes, steering, electronic control unit, etc.) are ready during the startup process of the vehicle and can be driven safely.

[0042] Furthermore, the braking service extracts the braking service provided by the main module, including: vehicle speed service, anti-lock braking system\traction control system\electronic stability control system intervention service and inertial measurement service; the braking information includes: vehicle speed information, anti-lock braking system\traction control system\electronic stability control system intervention information and inertial measurement data.

[0043] Among them, vehicle speed information refers to the vehicle speed data obtained from the vehicle speed sensor. Anti-lock braking system intervention (ABS intervention) means preventing wheel lock and maintaining the vehicle's steering ability during emergency braking; traction control system intervention (TCS intervention) means preventing drive wheel slip and improving vehicle traction when the vehicle accelerates; electronic stability control system intervention (ESC intervention) means maintaining vehicle stability by braking a single wheel and adjusting engine output when the vehicle loses control. Inertial measurement data refers to the vehicle acceleration, angular velocity and direction measured by the inertial measurement unit (IMU).

[0044] Furthermore, the steering service extracts the steering service provided by the main module, including: steering wheel angle service and steering wheel speed service; the steering information includes: steering wheel angle and steering wheel speed. The steering wheel angle refers to the rotation angle of the steering wheel, and the steering wheel speed refers to the rotation speed of the steering wheel, which can be obtained through corresponding sensors respectively.

[0045] In this way, each module in the vehicle shock absorption control system can act as a service provider, encapsulate the relevant information it obtains through service encapsulation, and achieve high utilization of service information without mixing useless information. The granularity of service information is currently based on functional requirements, and the service information involved in related functions is encapsulated into a unified service. Other modules can act as service receivers and receive service information in real time by pre-subscribing to related functions.

[0046] The shock absorption control main module is also used to perform control logic operations and generate control instructions based on the power information, the braking information, the steering information, the shock absorber solenoid valve status information, the vehicle height information and pre-set shock absorber parameters.

[0047] Among them, the shock absorption control main module performs logical operations based on power information, braking information, steering information, shock absorber solenoid valve status information, vehicle height information and pre-set shock absorber parameters to generate shock absorber control instructions. The specific method can refer to the shock absorber control principle in the prior art, and this application does not make any restrictions here.

[0048] The shock absorber solenoid valve service extraction module is used to obtain the control instruction by subscribing to the shock absorber solenoid valve control service of the shock absorption control main module.

[0049] The shock absorber solenoid valve service extraction module is also used to adjust the shock absorber solenoid valve according to the control instruction.

[0050] It should be noted that the brake service extraction main module, steering service extraction main module, shock absorber solenoid valve service extraction module, and vehicle height sensor service extraction module are all S2S modules, that is, the sensors and actuators are isolated through the service extraction module to achieve software and hardware separation, high cohesion and low coupling, and form a standard and universal service interface.

[0051] In this way, the shock absorber solenoid valve service extraction module can obtain the generated control instructions in real time by subscribing to the shock absorber solenoid valve control service of the shock absorption control main module, and adjust the shock absorber solenoid valve based on this control instruction.

[0052] Further, such as Figure 1 As shown in , the vehicle shock absorption control system provided in the embodiment of the present application also includes: a power mode main module 700; the shock absorption control main module is also used to obtain the current power state by subscribing to the power mode service of the power mode main module, and set the shock absorber according to the current power state.

[0053] Among them, common power states include Standby and IG ON, and different states represent different working modes of the vehicle power system. In the Standby state, the vehicle's main battery is still powered, but the ignition switch is turned off; most electronic devices and controllers enter low-power mode, and only certain basic functions remain running to save energy. In the IG ON state, the ignition switch is turned on, the vehicle's main battery powers all electronic devices and controllers, and all electronic devices and controllers enter full-function mode to perform their respective tasks.

[0054] Therefore, when the power state meets the preset requirements, such as the ignition switch is turned on, the shock absorber control main module can perform shock absorber settings.

[0055] Further, such as Figure 1 As shown in , the vehicle shock absorption control system provided in the embodiment of the present application also includes: an infotainment main module 800; the infotainment main module is used to receive shock absorber parameters set by the user through the vehicle-mounted screen; and obtain the current actual shock absorber parameters by subscribing to the shock absorber parameter display service of the shock absorption control main module, and display them through the vehicle-mounted screen.

[0056] Here, the main infotainment module can control the vehicle screen, and the vehicle screen interacts with the user through a displayed visual interactive interface. The visual interactive interface can display a vehicle setting page for the user to set the parameters of various components in the vehicle.

[0057] Exemplarily, for shock absorbers, the configurable shock absorber parameters displayed in the vehicle settings page include shock absorber comfort; shock absorber comfort refers to the vehicle's ability to buffer uneven road surfaces during driving, which directly affects the passenger's riding comfort and the vehicle's handling. In an embodiment of the present application, the user can obtain the current actual shock absorber parameters through the vehicle screen and adjust the shock absorber parameters through the vehicle screen. Correspondingly, the infotainment main module obtains the current actual shock absorber parameters by subscribing to the shock absorber parameter display service of the shock absorption control main module, and displays them in real time through the vehicle screen; and receives the desired shock absorber parameters modified by the user through the vehicle screen settings.

[0058] Correspondingly, when the shock absorber control main module is used to set the shock absorber according to the current power state, the shock absorber control main module is specifically used to: if the current power state meets the preset requirements, obtain the shock absorber parameters by subscribing to the shock absorber parameter setting service of the infotainment main module.

[0059] Furthermore, the modules included in the vehicle shock absorption control system perform data transmission based on SOME / IP services and through vehicle Ethernet.

[0060] A vehicle shock absorption control system based on SOA service provided by an embodiment of the present application includes: a shock absorption control main module, a power main module, a brake service extraction main module, a steering service extraction main module, a shock absorber solenoid valve service extraction module and a vehicle height sensor service extraction module; the shock absorption control main module is used to obtain power information by subscribing to the power service provided by the power main module; obtain braking information by subscribing to the brake service of the brake service extraction main module; obtain steering information by subscribing to the steering service of the steering service extraction main module; obtain shock absorber solenoid valve status by subscribing to the shock absorber solenoid valve service extraction module Service, to obtain the shock absorber solenoid valve status information; by subscribing to the vehicle height status service of the vehicle height sensor service extraction module, the vehicle height information is obtained; the shock absorption control main module is also used to perform control logic operations according to power information, braking information, steering information, shock absorber solenoid valve status information, vehicle height information and pre-set shock absorber parameters to generate control instructions; the shock absorber solenoid valve service extraction module is used to obtain control instructions by subscribing to the shock absorber solenoid valve control service of the shock absorption control main module; the shock absorber solenoid valve service extraction module is also used to adjust the shock absorber solenoid valve according to the control instructions.

[0061] In this way, through the SOA service-oriented approach, the shock absorber-related software is separated from the controller itself, and the shock absorption-related control software is deployed based on the use of regional controllers and central computing platforms, which can realize flexible changes in the software; the shock absorption-related control software is separated from the controller itself, and the service interface is exposed through service subscription, so as to achieve a certain degree of separation between the controller and the exposed service unit, and to a great extent reduce the changes in controller hardware during software iteration, thereby improving development efficiency and reducing development costs; through service subscription and service provision, through the communication method based on SOME / IP services and through the vehicle Ethernet, the line of sight is subscribed on demand and unnecessary information is filtered out.
