The car central control navigation host plays a vital role in autonomous driving technology.1. Core function supportHigh-precision map integration and update: The car central control navigation host usually integrates high-precision maps, which is an indispensable part of autonomous driving technology. High-precision maps provide centimeter-level road information, including lane lines, traffic signs, obstacles, etc., providing accurate positioning and environmental perception for autonomous driving vehicles. The navigation host can also update map data in real time to ensure that the vehicle always has the latest road information, which is crucial for responding to road changes, construction conditions, etc.Route planning and navigation: Based on high-precision maps, the navigation host can plan the optimal driving route and adjust it in real time to avoid congested or dangerous sections. This is of great significance to improving the driving efficiency and safety of autonomous driving vehicles. The navigation host can also work with the autonomous driving system to achieve accurate navigation and path tracking to ensure that the vehicle drives along the planned route.2. Sensor and camera collaborationData fusion and processing: As part of the on-board computing platform, the car central control navigation host is responsible for receiving and processing data from sensors (such as lidar, millimeter-wave radar, cameras, etc.). After fusion and processing, these data provide key information for autonomous driving decisions. The navigation host can also verify and compensate sensor data to improve the accuracy and reliability of the data.Environmental monitoring and early warning: By working in conjunction with sensors, the navigation host can monitor changes in the vehicle's surrounding environment in real time, such as the driving status of other vehicles and the dynamics of pedestrians. Once potential danger is discovered, the navigation host will issue an early warning in a timely manner to ensure the safety of the autonomous vehicle.3. Vehicle control and communicationVehicle control interface: The car central control navigation host usually has a vehicle control interface that can communicate and control the vehicle's power system, braking system, steering system, etc. This enables the autonomous vehicle to perform precise driving operations according to the instructions of the navigation host.Vehicle-to-vehicle communication (V2V) and vehicle-to-infrastructure communication (V2I): With the popularization of 5G technology, the navigation host can achieve more efficient vehicle-to-vehicle communication (V2V) and vehicle-to-infrastructure communication (V2I). This helps autonomous vehicles share information and work together with other vehicles and road infrastructure, further improving driving safety and efficiency.4. Personalized services and user experienceUser interaction and customization: car central control navigation host usually has a high-resolution touch screen and intelligent voice interaction function, providing drivers with a convenient operation experience. Through personalized settings, drivers can customize the navigation interface, music playlist, etc. according to their preferences and needs. In the autonomous driving mode, the navigation host can also automatically adjust the seat and rearview mirror position according to the driver's habits and preferences to provide a personalized driving experience.Real-time traffic information acquisition: The navigation host can obtain traffic information in real time, such as road conditions, congestion, traffic accidents, etc. This information is crucial for autonomous vehicles because they need to make corresponding driving adjustments based on real-time traffic conditions.The car central control navigation host plays a vital role in autonomous driving technology. It not only provides high-precision maps and route planning functions, but also works with sensors, cameras and other equipment to achieve environmental monitoring and early warning. At the same time, the navigation host also has a vehicle control interface and communication capabilities, which can realize information sharing and collaborative work with other vehicles and road infrastructure. In addition, the navigation host also provides personalized services and user experience, making autonomous driving technology closer to user needs.
