Publication number: 20240109585Abstract: Systems and techniques for determining a sideslip vector for a vehicle that may have a direction that is different from that of a heading vector for the vehicle. The sideslip vector in a current vehicle state and sideslip vectors in predicted vehicles states may be used to determine paths for a vehicle through an environment and trajectories for controlling the vehicle through the environment. The sideslip vector may be based on a vehicle position that is the center point of the wheelbase of the vehicle and may include lateral velocity, facilitating the control of four-wheel steered vehicle while maintaining the ability to control two-wheel steered vehicles.Type: ApplicationFiled: September 30, 2022Publication date: April 4, 2024Inventors: Joseph Funke, Liam Gallagher, Marin Kobilarov, Vincent Andreas Laurense, Mark Jonathon McClelland, Sriram Narayanan, Kazuhide Okamoto, Jack Riley, Jeremy Schwartz, Jacob Patrick Thalman, Olivier Amaury Toupet, David Evan Zlotnik

Publication number: 20240019156Abstract: A differentiable physics model of a building is used that defines thermodynamic relationships between zones of the building and a heating, ventilation, and air-conditioning (HVAC) system. A physics-constrained, data driven model learns behaviors of controlled components of the HVAC system. For each of a series of times during online operation of the HVAC system, past state values are recorded representing a performance of the HVAC system in the building and past inputs to the HVAC system to maintain the states. The past state values and the past inputs are input into the differentiable physics model and the data driven model to: jointly update first parameters of the differentiable physics model and second parameters of the data driven model, e.g., using moving horizon estimation; and determine a current input to the controlled components, e.g., using model predictive control.Type: ApplicationFiled: July 15, 2022Publication date: January 18, 2024Inventors: Saman Mostafavi, Harish Doddi, Yu-Wen Lin, David Schwartz

Patent number: 11753018Abstract: This document describes techniques and systems to make determinations of lane-type and roadway hypotheses in a road model. The road-perception system can fuse various forms of evidence to determine lane-type hypotheses and respective belief masses associated with the lane-type hypotheses. The road-perception system the computes, using the belief masses, a belief parameter and a plausibility parameter associated with the lane-type hypotheses. One or more roadway hypotheses are then determined using the lane-type hypotheses. The road-perception system then uses the respective belief parameter and plausibility parameter associated with the lane-type hypotheses to compute a belief parameter and a plausibility parameter associated with the roadway hypotheses. In this way, the described techniques and systems can provide an accurate and reliable road model with quantified uncertainty.Type: GrantFiled: February 17, 2021Date of Patent: September 12, 2023Assignee: Aptiv Technologies LimitedInventors: Bin Jia, David A.
