Abstract: In one embodiment, a system receives an initial reference line representing a route from a first location to a second location associated with an autonomous driving vehicle (ADV), where the initial reference line includes a number of reference line segments. The system smooths the line segments by applying a quadratic programming (QP) spline smoothing algorithm to the line segments. The system determines that the QP spline smoothing algorithm for the line segments fails to converge. The system adjusts (or enumerates) a location of an end point of a line segment. The system smooths the line segments by applying a QP spline smoothing algorithm to the adjusted (or enumerated) line segments. The system generates a smoothed reference line based on the smoothed line segments to be used as a reference line of the route to control the ADV.

Abstract: Techniques for allowing a vehicle equipped with at least one radar to take-off and land using radar return images of a landing site. The at least one radar generates radar return image(s) of the landing site, specifically of reflective symbols attached to the landing site, allowing the vehicle to orient itself to the landing site and providing information specific to the landing site. Position and velocity in relation to a landing site can be determined using at least one radar and a guidance and landing system. Using the position and velocity information, the guidance and landing system can guide the vehicle to and from the landing site and/or determine whether an obstacle requires the use of an alternate landing site.

Abstract: Technical solutions are described herein for steer-by-wire (SBW) steering systems to detect an end-of-travel condition dynamically and generate responsive handwheel torque for a driver. According to one or more embodiments, a steer-by-wire steering system includes a first controller that generates a plurality of torque commands. Generating the plurality of torque commands includes generating a curb torque command in response to detecting a curb condition in which road wheels are stationary despite a change in handwheel position, and generating an end-of-travel torque command in response to detecting an end-of-travel condition. The steer-by-wire steering system further includes an arbitrator module that determines a notification torque command by arbitrating between the plurality of torque commands, which comprises the curb torque command and the end-of-travel torque command.

Abstract: A robot has a component that is oriented relative to a chassis of the robot. For example, a display screen is mounted to the robot using a pan and tilt arrangement. During operation, trajectory data indicative of a trajectory is determined that specifies where the robot is intended to travel as it moves through an environment. This trajectory data is used to dynamically orient the component. For example, as the robot moves through the environment, the display screen would be oriented such that it appears to be “facing” a point in space that is associated with a point on the trajectory.

Abstract: Route guidance using less client device power and bandwidth is enabled by automatically selecting portions of a map to display with higher and lower levels of detail. An origin location and destination location are displayed at a higher level of detail, while portions between origin and destination are displayed at a lower level of detail. A user of a transportation service may request a ride, specifying her pickup location and destination locations using a map rendered at a higher level of detail. While waiting for pickup, and while en route to the destination location, the user may consult a map that is rendered at a lower level of detail. When multiple users participate as riders in a transportation service, sharing a common driver but each having different pickup and drop off locations, portions of a map may be rendered differently for each user.
