[0026] In some embodiments of the present invention, the interface module 28 includes a CAN data interface and a millimeter-wave radar interface. Specifically, the interface module uses a 28RS485 / 422 interface chip, which can be used for bus communication in two-wheeled vehicles.

[0027] Furthermore, the high-side drive module is connected to the vehicle's headlights and body heating device.

[0028] Furthermore, the H-bridge drive module is connected to the vehicle lock of the two-wheeled vehicle.

[0029] Specifically, through the MCU interface in conjunction with high-side and H-bridge drivers, vehicle lighting and locking functions can be achieved, enabling NFC near-field unlocking and Bluetooth contactless unlocking.

Centralized management offers advantages such as simplified wiring, fewer wiring harnesses, and reduced costs. With centralized management, each function can be centrally controlled and managed, enabling device scheduling. For example, headlights and ambient lighting can switch effects based on locking and unlocking scenarios, and sound effects can also be directly switched according to the scenario. It also enables vehicle fault diagnosis and OTA upgrades. The instrument panel is simply a display screen; modifications to the front of the vehicle only require changes to the display, leaving the controller unchanged, shortening the development cycle and improving system reliability. It supports Android and Linux systems, supports multiple application extensions, and supports mobile phone interconnection and voice control. It integrates display, driving recorder, ADAS safety warning, remote control, and vehicle network data, achieving human-vehicle and vehicle-road collaboration, laying the foundation for future autonomous driving.
