Abstract: In one embodiment, an autonomous driving system perceives a driving environment surrounding an ADV based on sensor data obtained from various sensors, including identifying one or more objects. For each of the objects, an arc curve is generated connecting the object and a current location of the ADV using a predetermined algorithm. A curvature of the arc curve is calculated. One of the arc curves is selected in which the curvature of the selected arc curve satisfies a predetermined condition, such as the lowest curvature amongst all objects. A reference line is then generated by connecting the selected object and the current location of the ADV. The connected line between the selected object and the ADV is utilized as a part of a reference line. The reference line is utilized to generate a trajectory to drive the ADV.

Abstract: A three-point-turn is planned and executed in the operation of an autonomous driving vehicle (ADV). A candidate route from a start point and going through an end point is determined, the start point and the end point being in lanes associated with opposite travel directions. The candidate route is categorized into partially overlapping first, second, and third segments. A total cost associated with the candidate route is determined based at least in part on the first and second segments. Whether the total cost is below a threshold cost is determined. In response to a determination that the total cost is below the threshold cost, the three-point-turn is planned based on the candidate route. Further, driving signals are generated based at least in part on the planned three-point-turn to control operations of the ADV.

The ECU is configured to generate and issue one or more control commands (e.g., throttle, brake, steering commands) based on the trajectory data to drive the ADV according to the trajectory.

Abstract: According to various embodiments, systems and methods for smoothing a reference line for an autonomous driving vehicle are described. In an exemplary method, a raw reference line can be generated from a high definition map and routing results, and can be truncated based on a predetermined formula. The truncated raw reference line can include a number of points, each point representing a position of an autonomous driving vehicle in a global coordinate system. The number of points can be converted to points in a local coordinate system, where a polynomial curve that best fits the points are generated. The polynomial curve can subsequently be used to generate a new vertical coordinate for a horizontal coordinate of each of the number of points. The new vertical coordinates and their corresponding horizontal coordinates can be converted back to the global coordinate system. The polynomial curve can be used to derive a heading, a kappa, and a dkappa for each point in the global coordinate system.

Abstract: An ADV perceives a driving environment surrounding the ADV based on sensor data obtained from a variety of sensors mounted on the ADV including, for example, perceiving and recognizing a corner the ADV may be about to turn. Based on the perception data of the driving environment, a set of features representing the characteristics of an entrance point of a corner that the ADV is about to turn. Based on the characteristics of the corner, an entrance point of the corner is determined. Based on the entrance point, a lookup operation is performed in a corner mapping table to locate a mapping entry matching the entrance point. A turning radius is then obtained from the mapping entry of the corner mapping table. The turning radius obtained from the corner mapping table is then utilized to plan a trajectory (e.g., steering angle) to drive the ADV to turn the corner.

The first member comprises a first main body and a first connecting portion, the second member comprises a second main body and a second connecting portion. The first main body and the second main body face each other, and the first connecting portion is cooperated with and fixedly connected to the second connecting portion. Because the first member and the second member are independent members, and they can be formed by separately cutting a sheet. Because the first member and the second member each are small in size and simple in structure, and they can be rapidly formed by using less material, the whole structure of the buffering member is simple and the buffering member uses less material, thereby maximally improving the utilization rate of the sheet.
