Embodiment Construction

[0049] The systems and methods described herein enable the testing of truly networked autonomous vehicles (CAVs) using augmented reality on the road, adding simulated environmental objects such as additional vehicles, pedestrians, and other obstacles to the vehicle under test. can be seen in the surrounding environment. This is typically done by running a real-time simulation synchronized with the operation of the CAV on the road, using a mapping model of the traffic control system and road used in the test and real-time vehicle state information of the CAV under test. With this information, the simulation can add virtual elements, such as other vehicles moving along the road, and these virtual elements can be fed back to the CAV again in real-time to act as sensor input data for the CAV, causing the CAV to incorporate these additional simulated Vehicles and other objects are treated as real objects that exist in the environment in which they operate. This allows the construc...

Abstract

A system and method for simulating a real roadway environment that can be used for testing of a real connected autonomous vehicle (CAV) on roadways using augmented reality to add simulated virtual environmental objects such as additional vehicles, pedestrians, and other obstructions to the nearby surroundings seen by the CAV under test. The method carried out by the system includes: receiving vehicle status information indicating the location of a connected real vehicle as it moves along a roadway; and generating a simulated environment of the real vehicle on the roadway using a mapped model of the roadway and the vehicle status information. The simulated environment includes one or more virtual objects such as vehicles, pedestrians, or other obstructions, and these simulated virtual objects may be sent to the real vehicle for testing of its response without requiring the use of real vehicles, pedestrians, or other obstructions.

Description

[0001] Statement Regarding Federally Funded Research [0002] This invention was made with Government support under Grant No. 69A3551747105 awarded by the US Department of Transportation. The government has certain rights in this invention. technical field [0003] The present invention relates to methods and systems for testing connected autonomous vehicles on roads, and to methods and systems for generating simulated environments using data from the real environment in which connected autonomous vehicles and their operations operate. Background technique [0004] The development and eventual deployment of autonomous vehicles typically involves several phases, including an initial design and prototyping phase, a controlled testing phase, and a real-world testing phase of operating the vehicle on open (public) roads. The advantage of a controlled testing phase is that vehicle testing can be carried out in a safe, controlled environment where responsiveness and accuracy of v...
