[0003] For example, data transmission and interaction efficiency between devices such as the vehicle's dashboard, central control display, and onboard computer is low, making it difficult to quickly and accurately convey critical information to the driver. Furthermore, the lack of standardized communication protocols between different devices increases system complexity and maintenance costs.

[0004] SPI communication, as a high-speed, full-duplex, synchronous communication bus, boasts advantages such as high communication speed, high reliability, and ease of implementation. Integrating SPI communication into a driving control platform can effectively improve the data transmission efficiency and stability between various vehicle components, achieving the integration and intelligence of the driving control platform. However, currently, there is a lack of such integrated driving control platforms with SPI communication on the market. Therefore, those skilled in the art have provided an integrated driving control platform with SPI communication to address the problems mentioned in the background section. Utility Model Content

The main control unit adopts a high-performance microprocessor, and the main control unit communicates bidirectionally with the instrument panel module, the central control display module, the on-board computer module, and the vehicle sensor modules via the SPI communication bus.

[0017] The instrument panel module receives real-time vehicle data sent by the main control unit via the SPI communication bus and displays the data in the form of pointers, numbers, and indicator lights. It can also feed back driver operation commands to the main control unit via the SPI communication bus. The instrument panel module uses an industrial-grade LCD screen and a matching driver chip, such as an ILI9341-driven TFT LCD screen. The SPI interface of the screen is connected to the SPI interface of the main control unit, and the input pins of the buttons are connected to the general purpose input / output port (GPIO) of the main control unit to receive driver operation commands.

[0018] The central control display module is connected to the main control unit via an SPI communication bus. It receives and displays multimedia information, navigation information, and vehicle setting information. It can also send driver interaction operation commands to the main control unit via the SPI communication bus. The SPI interface of the touch screen central control display module is connected to the main control unit to ensure that the response data of the touch operation can be accurately transmitted to the main control unit, and at the same time, the display data sent by the main control unit is correctly displayed on the screen.

[0019] The vehicle computer module receives vehicle system status data sent by the main control unit via the SPI communication bus, performs real-time monitoring and diagnosis of key vehicle components, and sends fault information to the main control unit via the SPI communication bus.

It is also connected to the sensor interfaces and actuator drive interfaces of various key vehicle components to realize the monitoring and control of the vehicle system.

[0020] The vehicle sensor module includes a speed sensor, a rotation speed sensor, a fuel level sensor, and a coolant temperature sensor. Each sensor collects vehicle parameter data in real time and sends the data to the main control unit via the SPI communication bus. The analog signals output by the sensors are converted into digital signals and then transmitted to the main control unit via the SPI bus. The sensors are installed according to the actual layout of the vehicle to ensure accurate collection of the vehicle's operating parameters.

[0021] The communication module uses a high-speed SPI transceiver chip with multiple SPI interfaces to manage and coordinate SPI communication between modules, buffer, schedule, forward, and verify and correct data. Its multiple SPI interfaces are connected to the main control unit, instrument panel module, central control display module, vehicle computer module, and vehicle sensor module, respectively. By configuring the chip's registers, parameters such as SPI communication rate and data format are set to ensure stable and reliable communication between modules.

[0022] In this embodiment, the main control unit filters, analyzes, and calculates the received vehicle sensor data. Based on the driver's operation commands and vehicle status, it generates corresponding control commands and sends them to each module. Simultaneously, it writes a communication protocol parsing program with other modules to ensure correct data transmission, reception, and processing. The instrument panel module receives data sent by the main control unit via SPI communication and displays corresponding graphics and numbers on the screen according to the data type, such as the rotation of the speedometer pointer and the digital display of fuel level.

Simultaneously, it receives control commands from the main control unit to precisely control various vehicle systems; the communication module buffers and processes the received data, forwarding it to the appropriate modules according to priority and time order. A data verification and error correction program is written to perform CRC checks on the transmitted data; if an error is detected, a retransmission is requested promptly. The working principle of this invention is as follows: During use, the integrated SPI communication driving control platform is installed on the vehicle. After rigorous testing and debugging, it ensures normal communication between modules, accurate data transmission, and stable and reliable system functions. Through the coordinated operation of the above hardware, integrated and intelligent vehicle driving control is achieved, improving the overall performance and driving experience of the vehicle. Multiple driving-related functional modules are integrated into one control platform. Through the unified coordination of the main control unit, centralized display and unified control of vehicle information are achieved. The driver does not need to switch between multiple scattered devices, improving the convenience and comfort of driving control. Simultaneously, it enables real-time and accurate vehicle status monitoring and rapid fault diagnosis feedback, allowing the driver to understand abnormal vehicle conditions immediately and take timely measures to avoid potential safety accidents. For example, when the onboard computer detects a braking system fault, it can quickly transmit the fault information to the instrument panel and central control display screen via SPI communication, alerting the driver and prompting corresponding emergency operations. Using SPI communication technology, high-speed, synchronous, full-duplex data transmission between modules is achieved, with data transmission rates reaching Mbps levels. Compared to traditional communication methods, this significantly reduces data transmission latency, ensuring that the driver can obtain the latest vehicle information in a timely manner and make accurate judgments.
