Patents by Inventor Wenshuai ZHOU

Wenshuai ZHOU has filed for patents to protect the following inventions. This listing includes patent applications that are pending as well as patents that have already been granted by the United States Patent and Trademark Office (USPTO).

  • Patent number: 11407424
    Abstract: Provided are a system and a method for testing an ability of an automated vehicle to pass a traffic circle without traffic lights. The system includes an automated vehicle, a traffic circle, a control center, an attitude sensor and a panorama camera. In the method, the control center receives a test request and then sends a driving command to drive the automated vehicle to enter the traffic circle to start the test. The attitude sensor obtains a tilt angle and sends it to the control center in real time. The panorama camera is configured to obtain a driving trajectory, a driving speed and a state of turn signals of the automated vehicle. The obtained information is compared to a standard by the control center to evaluate the ability of the automated vehicle to pass the traffic circle without traffic lights.

  • Patent number: 11308330
    Abstract: Provided are a method and a device for constructing autonomous driving test scenes, a terminal and a readable storage media. Primitive scenes are extracted from real traffic scenes to establish a primitive scene description model. The values of the description variables are selected from distribution intervals of the description variables of the primitive scenes, and the description variables are randomly sampled based on the distribution of the description variables to generate test primitive scenes by adopting an importance sampling based Monte Carlo method. The test primitive scenes are recombined according to the parameters of the elements of the test scene to generate the test scene. The present invention can directly simulate the actual complex system, so as to avoid the result distortion caused by the simplification of the complex system.

  • Publication number: 20210221391
    Abstract: Provided herein relates to the performance testing of automated vehicles, and more particularly to a system and a method for testing cooperative driving capability of an automated vehicle. The system includes a target vehicle, a test road and a control center, where the automated vehicle and the target vehicle are located on the test road, and the control center is located beside the test road. A speed sensor and a binocular camera are provided on the automated vehicle. The speed sensor and the binocular camera are connected to the control center through a wireless communication device, respectively. An on-board device is provided on the target vehicle and is connected to the control center through the wireless communication device. The method provided herein is used to determine the responsiveness of automated vehicles according to the speed relationship and distance between the automated vehicle and the target vehicle.
