  • Publication number: 20240161670
    Abstract: Dynamic refresh rate (DRR) switching is used to dynamically update a refresh rate of content presented on an interface. When a first application and a second application are presented on a user interface at a first refresh rate; a request may be received to temporarily boost the first refresh rate to a second, higher, refresh rate. DRR switching is initiated as the first refresh rate is temporarily boosted to a second refresh rate. Applications that are opted in to the second refresh rate receive signals to refresh content at the second refresh rate, while applications that are not opted in to the second refresh rate receive signals to refresh content at a virtualized refresh rate that matches the first refresh rate. Thus, the first application refreshes content at the first refresh rate and the second application refreshes content at the second, higher refresh rate, providing a smooth user experience without unnecessarily utilizing power consumption.

  • Patent number: 11780452
    Abstract: A model of a system of an intelligent vehicle is trained and optimized using system operation data of the intelligent vehicle in a normal running state. The system operation data of the intelligent vehicle in a running state is collected in real time. Sensor data of the system operation data is de-noised, and feature extraction and screening are performed for a fatal sensor fault to reconstruct the system operation data. The reconstructed system operation data is inputted into the trained model to output system state data of the intelligent vehicle in the running state. The system state data is compared with a set threshold. If the system state data exceeds the set threshold, an actuator corresponding to the system state data is determined to have a fault. In addition, a system for a fault diagnosis of the intelligent vehicle is further provided.

    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.
