一个在量产中很容易被忽略重要性的元素：导航信息SD

Core Viewpoint - The article discusses the application of navigation information in autonomous driving, emphasizing its importance in providing lane guidance, waypoint information, and reference lines to enhance vehicle path planning and control [2][4][32]. Group 1: Navigation Information Application - Navigation information SD/SD Pro is currently utilized in many production solutions, offering lane and waypoint data to provide a comprehensive view for drivers [2]. - The core responsibilities of the navigation module include providing reference lines, which significantly reduce planning pressure by offering a predefined driving path [4]. - Additional functionalities include providing planning constraints and priorities, as well as path monitoring and replanning [5]. Group 2: Path Planning and Behavior Guidance - Global path planning at the lane level involves searching for the optimal lane sequence to reach a target lane [6]. - The navigation information aids behavior planning by providing clear semantic guidance, allowing vehicles to prepare for lane changes, deceleration, and yielding in advance [6]. Group 3: Course Overview - The article outlines a course focused on practical applications in autonomous driving, covering topics such as end-to-end algorithms, navigation applications, and trajectory optimization [24][29]. - The course is designed for advanced learners and aims to provide insights into integrating perception tasks and designing learning-based control algorithms [29][37]. - It includes practical sessions on various algorithm frameworks, including one-stage and two-stage models, and emphasizes the importance of navigation information in production applications [30][31][32].
