Patent number: 11886187Abstract: Aspects of the disclosure relate to controlling a vehicle in an autonomous driving mode using trajectories. For instance, a trajectory may be received by one or more first computing devices from one or more second computing devices. While the first computing devices are controlling the vehicle in the autonomous driving mode based on the trajectory, an error may be generated by second computing devices. Whether the error is a recoverable error may be determined, and if so, the second computing devices attempt to generate a new trajectory. When the second computing devices generate the new trajectory, the vehicle may be controlled by the first computing devices according to the new trajectory.Type: GrantFiled: May 3, 2022Date of Patent: January 30, 2024Assignee: Waymo LLCInventor: Ioan-Alexandru Sucan

Patent number: 11884317Abstract: A method for positioning a steering wheel of a motor vehicle in a rest position and/or an easy-entry position. The steering wheel has an operative connection to an adjustment means via which the steering wheel can be moved in a steering wheel adjustment field. A most recently set steering wheel position is established as the current steering wheel position. A target position in the steering wheel adjustment field, which represents the maximum increase in space for a driver in relation to the currently set steering wheel position, is determined. This target position is established as a rest position and/or as an easy-entry position. The steering wheel is moved into the established rest position and/or easy-entry position.Type: GrantFiled: July 16, 2021Date of Patent: January 30, 2024Assignee: AUDI AGInventors: Sebastian Loos, Richard Schroeder

Patent number: 11873042Abstract: A method and a system for vehicle steering control by controlling a feedback torque actuator (130) in series with an angle overlay actuator (140) in a vehicle steering system (100) to provide a target feedback torque and a target overlay angle. The feedback torque actuator (130) is arranged above the angle overlay actuator (140). The angle overlay actuator (140) is controlled so that a variable steering ratio and an additional overlay angle are provided, and the feedback torque actuator (130) is controlled using a reference generator so that the torque is controlled to provide a target steering feel, resulting in the angle overlay being controlled at the same time as the steering-wheel torque being controlled whereby a target overlay angle and a good steering feel are achieved.Type: GrantFiled: March 16, 2019Date of Patent: January 16, 2024Assignee: SENTIENT IP ABInventors: Johan Hultén, Jochen Pohl, Henrik Weiefors, Ulf Löfqvist

Patent number: 11866066Abstract: Systems and methods to perform behavioral planning in an autonomous vehicle from a reference state involve generating a set of actions of a fixed size and fixed order according to a predefined methodology. Each action is a semantic instruction for a next motion of the vehicle. A set of trajectories is generated from the set of actions as an instruction indicating a path and a velocity profile to generate steering angles and accelerations for implementation by the vehicle. A trajectory filter is applied to filter the set of trajectories such that unfiltered trajectories are candidate trajectories. Applying the trajectory filter includes assessing the path and velocity profile indicated by each of the set of trajectories. A selected trajectory is used to control the vehicle or the action that corresponds to the selected trajectory is used in trajectory planning to generate a final trajectory that is used to control the vehicle.Type: GrantFiled: September 30, 2020Date of Patent: January 9, 2024Assignee: GM GLOBAL TECHNOLOGY OPERATIONS LLCInventor: Roi Reshef
