Publication number: 20210163037Abstract: In one embodiment, instead of using map data, a relative coordinate system is utilized to assist perception of the driving environment surrounding an ADV for some driving situations. One of such driving situations is driving on a highway. Typically, a highway has fewer intersections and exits. The relative coordinate system is utilized based on the relative lane configuration and relative obstacle information to control the ADV to simply follow the lane and avoid potential collision with any obstacles discovered within the road, without having to use map data. Once the relative lane configuration and obstacle information have been determined, regular path and speed planning and optimization can be performed to generate a trajectory to drive the ADV. Such a perception system is referred to as a relative perception system based on a relative coordinate system.Type: ApplicationFiled: April 18, 2018Publication date: June 3, 2021Inventors: Fan ZHU, Qi KONG, Yuchang PAN, Feiyi JIANG, Xin XU, Xiaoxin FU, Zhongpu XIA, Chunming ZHAO, Liangliang ZHANG, Weicheng ZHU, Li ZHUANG, Haoyang FAN, Hui JIANG, Jiaming TAO

Publication number: 20210155111Abstract: Disclosed is a method for establishing an active distribution network planning model considering location and capacity determination of an electric vehicle charging station. In terms of location and capacity determination of electric vehicle charging stations, a traffic flow of electric vehicles is converted into a charging demand flowing in a traffic network, and an electric vehicle traffic network model is established based on an M/M/s queuing model and a flow capturing location model in the traffic field. A distributed generation (including wind power and photovoltaic) and load model is established, based on a time series method. An energy storage element model in a power distribution network is established based on an idea of equivalent load. A nested planning model is established by taking economy and reliability of a power distribution network and a maximum traffic flow intercepted by the electric vehicle charging stations as objectives.Type: ApplicationFiled: December 17, 2020Publication date: May 27, 2021Inventors: Shiyuan Ni, Linyao Zhang, Jieyun Zheng, Tingting Lin, Pengjia Shi, Guilian Wu, Li Zhuang, Yi Liang, Xin Liu, Changzhui Lin

Patent number: 10754339Abstract: According to some embodiments, a system calculates a first trajectory based on a map and a route information. The system generates a path profile based on the first trajectory, traffic rules, and an obstacle information describing one or more obstacles perceived by the ADV. The system generates a speed profile based on the path profile, where the speed profile includes, for each of the obstacles, a decision to yield or overtake the obstacle. The system performs a quadratic programming optimization on the path profile and the speed profile to identify an optimal path with optimal speeds.

Patent number: 10613489Abstract: Driving parameters (e.g., speed, heading direction) that an autonomous driving vehicle (ADV) likely utilize as target driving parameters are grouped into a number of ranges and one of the driving parameters in each range is selected as a driving parameter representative or a target driving parameter representing the respective range or segment. For each of the target driving parameters representing the ranges, a particle swarm optimization method is utilized to derive a set of most optimized coefficients for a controller (e.g., speed controller, steering controller) for controlling an ADV. A driving parameter to coefficient (parameter/coefficient) mapping table is generated to map a particular driving parameter representing a range of driving parameter to a set of one or more coefficients of a particular controller. The parameter/coefficient mapping table is utilized at real-time to configure a controller in response to a particular target driving parameter using the corresponding coefficients.Type: GrantFiled: June 20, 2017Date of Patent: April 7, 2020Assignee: BAIDU USA LLCInventors: Qi Luo, Qi Kong, Fan Zhu, Xiang Yu, Sen Hu, Li Zhuang, Weicheng Zhu, Guang Yang, Jingao Wang

Patent number: 10579062Abstract: In one embodiment, a computer system generates a first vehicular path based on map information. The system collects data points representing geographical coordinates of vehicles that drove on a vehicular path lane at different points in time. The system segments the first vehicular path into path segments based on the collected data points. For each of the path segments, the system applies a smoothing function to select a subset of the data points that are within a predetermined proximity of the corresponding path segment and calculates a segment reference point to represent the path segment by combining the selected data points. The segment reference points of the path segments of the first vehicular path are interpolated to generate a second vehicular path such that the second vehicular path is used as a reference line to control ADVs driving on the first vehicular path.Type: GrantFiled: May 31, 2017Date of Patent: March 3, 2020Assignee: BAIDU USA LLCInventors: Weicheng Zhu, Li Zhuang, Qi Luo, Qi Kong, Fan Zhu

Patent number: 10569651Abstract: When generating a control command of an autonomous driving vehicle (ADV), a pitch status and/or a roll status of the road is determined. The control command is adjusted based on the pitch status and the roll status. For example, when an ADV is driving on an uphill or downhill road, a pitch status of the road is determined and a speed control command will be generated based on the pitch status of the road, such that the ADV have a similar acceleration rate as of driving on a flat road. Similarly, when the ADV is driving on a road that is tilted or rolled left or right, a roll status of the road is determined and a steering control command will be generated in view of the roll status of the road, such that the ADV have a similar heading direction as of driving on a flat road.Type: GrantFiled: May 15, 2017Date of Patent: February 25, 2020Assignee: BAIDU USA LLCInventors: Fan Zhu, Qi Kong, Qi Luo, Xiang Yu, Sen Hu, Li Zhuang, Liangliang Zhang, Weicheng Zhu, Haoyang Fan, Yajia Zhang, Guang Yang, Jingao Wang
