Publication number: 20240092385Abstract: In a driving policy determining method, for each object, a first target motion trajectory of the object is calculated on a premise that the object does not collide with another object that moves based on an initial motion trajectory. Then, for the ego vehicle, a second target motion trajectory of the ego vehicle is calculated on a premise that the ego vehicle does not collide with another object that moves based on a first target motion trajectory. Then, a driving policy is determined based on the second target motion trajectory of the ego vehicle and a first target motion trajectory of at least one game object. The foregoing operations are repeated until the determined driving policy matches an initial driving policy.Type: ApplicationFiled: November 28, 2023Publication date: March 21, 2024Inventors: Shixiong Kai, Bin Wang, Wulong Liu

Patent number: 11897454Abstract: This application provides a method for determining an automatic parking strategy. The method includes: determining, a target parking action corresponding to a current parking stage performing the target parking action; obtaining feedback information, where the feedback information is used to indicate whether a result of performing the target parking action reaches a predetermined objective, and the predetermined objective is a predetermined position of the vehicle relative to a target parking spot, and/or the predetermined objective is a status of the vehicle in the parking process; and updating the automatic parking strategy based on the feedback information. In the foregoing method, the entire parking process is divided into several parking stages, and a control strategy is obtained by using a different method at each stage. This can increase a success rate of automatic parking in a complex parking scenario.Type: GrantFiled: December 28, 2020Date of Patent: February 13, 2024Assignee: HUAWEI TECHNOLOGIES CO., LTD.Inventors: Yuzheng Zhuang, Qiang Gu, Wulong Liu

Publication number: 20230252215Abstract: Methods and systems for generating a floorplan for a circuit are disclosed. A netlist graph of the circuit and block features associated with blocks of the circuit are obtained. A reinforcement learning (RL) agent is used to generate a sequence of corner block list (CBL) actions. Each CBL action is generated by: generating a current state embedding representing a current state of the floorplan; and inputting the current state embedding to a policy network of the RL agent to generate a predicted output vector, which is used to generate the CBL action. After each CBL action is generated, the current CBL representation of the floorplan and the block features are updated to reflect the state of the floorplan after applying the CBL action. The CBL representation is outputted as a final floorplan after all blocks have been placed.Type: ApplicationFiled: July 15, 2022Publication date: August 10, 2023Inventors: Zhanguang ZHANG, Mohammad AMINI, Yingxue ZHANG, Wulong LIU
