Patent number: 11787394Abstract: A system for supervisory control for eAWD and eLSD in a motor vehicle includes a control module, and sensors and actuators disposed on the motor vehicle. The sensors measure real-time motor vehicle data, and the actuators alter behavior of the motor vehicle. The control module receives the real-time data; receives one or more driver inputs to the motor vehicle; determines a status of a body of the motor vehicle; determines a status of axles of the motor vehicle; determines a status of each wheel of the motor vehicle; and generates a control signal to the actuators from the driver inputs and the body, axle, and wheel statuses. The control module also exercises supervisory control by actively adjusting constraints on the control signal to each of the actuators where actively adjusting constraints on the control signal alters boundaries of control actions in response to the one or more driver inputs.Type: GrantFiled: December 1, 2021Date of Patent: October 17, 2023Assignee: GM GLOBAL TECHNOLOGY OPERATIONS LLCInventors: Reza Hajiloo, SeyedAlireza Kasaiezadeh Mahabadi, Shamim Mashrouteh, Seyedeh Asal Nahidi, Ehsan Asadi, Yubiao Zhang, Bakhtiar B.

Patent number: 11788455Abstract: Methods and systems are provided for recirculation of an engine exhaust gas. The system includes an engine, an exhaust system configured to channel exhaust gas from the engine to an outlet, an aftertreatment device, an exhaust recirculation system configured to divert at least some of the exhaust gas as recirculated exhaust gas from a first position in the exhaust system downstream of the aftertreatment device, through a buffer tank, and to a second position in the exhaust system upstream of the aftertreatment device, wherein the recirculated exhaust gas is combined with the exhaust gas at the second position, a controller configured to, by a processor, selectively operate the exhaust recirculation system to control the exhaust recirculation system to divert the exhaust gas and thereby cause the recirculated exhaust gas to be treated with the aftertreatment device more than once with sequentially increased catalyst temperatures.Type: GrantFiled: November 15, 2022Date of Patent: October 17, 2023Assignee: GM GLOBAL TECHNOLOGY OPERATIONS LLCInventors: Chengke Liu, Rafat F.

Patent number: 11791641Abstract: A protection system for a high-voltage component includes a switching circuit and a protection controller. The switching circuit changes a variable arrangement of multiple battery packs between a parallel arrangement and a series arrangement. The protection controller commands the switching circuit into the series arrangement in response to a recharging session, commands a current flow in the recharging session, measures a measured voltage between an input node and a floating chassis ground of the high-voltage component, advances a timer while the measured voltage indicates a presence of an improper voltage, and cancels the recharging session in response to the presence of the improper voltage for greater than an exposure time. The recharging session provides a direct-current fast-charging voltage to battery packs in the series arrangement, and is greater than the battery voltage.Type: GrantFiled: November 17, 2021Date of Patent: October 17, 2023Assignee: GM Global Technology Operations LLCInventors: Konking Wang, Emil Francu, Li-Pen J. Ho, Kevin J. Robinet

Patent number: 11791558Abstract: An ultra wide band antenna includes a ground plane and an antenna body. The antenna body includes a planar portion arranged above and parallel to the ground plane. A first tapered portion extends in a perpendicular direction from a first edge of the planar portion towards the ground plane. A lower edge of the first tapered portion is spaced from the ground plane by a predetermined gap. A second tapered portion extends in a perpendicular direction from a second edge of the planar portion towards the ground plane and includes a first portion that is connected to the ground plane.Type: GrantFiled: August 23, 2021Date of Patent: October 17, 2023Assignee: GM GLOBAL TECHNOLOGY OPERATIONS LLCInventor: Uriel Zvi Odes

Patent number: 11790775Abstract: Methods and systems are provided for indicating a driving situation including at least one vehicle. The system includes a first processor, a second processor and an external device. A first processor obtains driving information, encodes the driving information and communicates the encoded driving information to the second processor. The second processor receives and decodes the encoded driving information. The second processor further allocates a predefined indication pattern to the decoded driving information, wherein the predefined indication pattern includes a graphical representation of an upcoming driving event involving the vehicle. An external device visualizes a current driving situation including the vehicle together with the predefined indication pattern.Type: GrantFiled: August 31, 2021Date of Patent: October 17, 2023Assignee: GM GLOBAL TECHNOLOGY OPERATIONS LLCInventors: Prakash Mohan Peranandam, Ramesh Sethu, Arun Adiththan, Joseph G D Ambrosio
