    摘要: Aspects of the disclosure relate generally to detecting discrete actions by traveling vehicles. The features described improve the safety, use, driver experience, and performance of autonomously controlled vehicles by performing a behavior analysis on mobile objects in the vicinity of an autonomous vehicle. Specifically, an autonomous vehicle is capable of detecting and tracking nearby vehicles and is able to determine when these nearby vehicles have performed actions of interest by comparing their tracked movements with map data.

    摘要: In a navigation method, at least one constant travel characteristic (CONST_KW) is determined that is representative of a vehicle-specific energy requirement with respect to a predetermined trip length at quasi-constant speed and on a quasi-level stretch. At least one dynamic characteristic (DYN_KW) is determined that is representative of a vehicle-specific energy requirement with respect to a predetermined trip length at quasi-dynamic speed and on a quasi-level stretch. The constant travel characteristic (CONST_KW) is respectively adapted on the basis of at least one vehicle-specifically determined energy consumption characteristic (EV_KW) for a traveled route segment that has been recognized as quasi-level and in which a quasi-constant speed was detected. To determine an expected energy requirement for a predetermined driving route (RT) with several route segments (STA), the individual route segments (STA) are each made available either as a constant travel segment (CONST_STA) or as a dynamic travel segment (DYN_STA). For each route segment (STA), the estimated route segment energy requirement characteristic (ST_EB_KW) is determined on the basis of a respective constant travel characteristic (CONST_KW) in the event of a route segment (STA) made available as a constant travel segment (CONST_STA) and on the basis of a respective dynamic characteristic (DYN_KW) in the event of a route segment made available as a dynamic travel segment. An estimated route energy requirement characteristic (RT_EB_KW) for the predetermined driving route (RT) is determined on the basis of the respective route segment energy requirement characteristics (ST_EB_KW).

    摘要: Systems and methods for operating autonomous waterborne vessels in a safe manner. The systems include hardware for identifying the locations and motions of other vessels, as well as the locations of stationary objects that represent navigation hazards. By applying a computational method that uses a maritime navigation algorithm for avoiding hazards and obeying COLREGS using Velocity Obstacles to the data obtained, the autonomous vessel computes a safe and effective path to be followed in order to accomplish a desired navigational end result, while operating in a manner so as to avoid hazards and to maintain compliance with standard navigational procedures defined by international agreement. The systems and methods have been successfully demonstrated on water with radar and stereo cameras as the perception sensors, and integrated with a higher level planner for trailing a maneuvering target.

    摘要: A computer-implemented method for generating at least one segment of an offset path for a vehicle based on at least one segment of a base path is provided. The at least one segment of the base path is represented by a stored set of data points. The computer-implemented method includes comparing the at least one segment of the base path to a curvature constraint to determine if the at least one segment of the base path violates the curvature constraint. The curvature constraint is based on a characteristic of the vehicle and a desired offset distance from the at least one segment of the base path. The characteristic reflects the vehicle's ability to traverse at least one segment of a path. The method further includes modifying the at least one segment of the base path to satisfy the curvature constraint, if the at least one segment of the base path violates the curvature constraint. At least one segment of an offset path for the vehicle to follow is generated based upon the desired offset distance from the modified at least one segment of the base path.

    摘要: An automatic timing measurement system that provides a measure of time of passage of a watercraft through a prescribed course. Algorithms based on inertial or other estimates augmented by GPS speed/position measurements are used to track position of a watercraft. Said position estimates are used to allow the locations of prescribed courses to be mapped and memorized. Algorithms are then used to allow the apparatus to automatically detect passage of a watercraft through mapped courses for the purpose of measuring and reporting time of passage of said watercraft past key points in said course, and for modifying the behavior of the speed control portion of the apparatus if necessary at certain points in the mapped course. A measure of accuracy of driver steering can be provided along with the ability to automatically steer the watercraft through the course if “steer-by-wire” mechanism is available. GPS speed control is augmented with a secondary velocity measurement device that measures speed over water resulting in an optional user selectable real-time compensation for water current. Furthermore, GPS is used as the key input to produce boat speed-based pull-up profiles.

    摘要: An emergency vehicle traffic light preemption system for preemption of traffic lights at an intersection to allow safe passage of emergency vehicles. The system includes a real-time status monitor of an intersection which is relayed to a control module for transmission to emergency vehicles as well as to a central dispatch office. The system also provides for audio warnings at an intersection to protect pedestrians who may not be in a position to see visual warnings or for various reasons cannot hear the approach of emergency vehicles. A transponder mounted on an emergency vehicle provides autonomous control so the vehicle operator can attend to getting to an emergency and not be concerned with the operation of the system. Activation of a priority-code (i.e. Code-3) situation provides communications with each intersection being approached by an emergency vehicle and indicates whether the intersection is preempted or if there is any conflict with other approaching emergency vehicles. On-board diagnostics handle various information including heading, speed, and acceleration sent to a control module which is transmitted to an intersection and which also simultaneously receives information regarding the status of an intersection. Real-time communications and operations software allow central and remote monitoring, logging, and command of intersections and vehicles.
