Abstract
An automated vehicle can generate a path. Sensor data of at least a forward portion of an external environment of the vehicle can be acquired. One or more travel lane markers of a current travel path of the automated vehicle can be identified from the acquired sensor data. A detection range of the acquired sensor data can be determined. A set of travel lane parameters based on the identified one or more travel lane markers can be determined. In at least some instances, the set of travel lane parameters can include at least: offset, curvature, curvature derivative, and yaw. It can be determined whether any of the determined travel lane parameters are reliable based on the determined detection range. In one or more arrangements, a vehicle path can be determined based at least partially on the travel lane parameters that are determined as being reliable.
