Abstract: A method of active energy management for a vehicle including a rechargeable energy storage system (RESS). The method includes: calculating, via a controller programmed with a usable energy algorithm, a usable energy of the at least one power module based on an anode lithium surface density; comparing, via the controller, the usable energy calculated with a first threshold; providing, via the controller, a first notification to a user when the usable energy calculated reaches a first threshold; providing, via the controller, a second notification to the user when the usable energy calculated reaches a second threshold, providing a third notification to the user when the usable energy calculated reaches a third threshold, and suggesting actions to the user based on the notifications.

Abstract: A damping panel includes a first metal and a second metal. The first metal has a first surface and a second surface opposite the first surface. The second metal portion has a third surface and a fourth surface opposite the third surface. A fixed region is where the second surface of the first metal is fixed to the third surface of the second metal. A non-fixed region is where the second surface is not fixed to the third surface. A cavity is disposed between the second surface and the third surface at the non-fixed region. A damping material is disposed on at least one of: at least a portion of the cavity on the second surface, at least a portion of the cavity on the third surface, at least a portion of the first surface, and at least a portion of the fourth surface.

Abstract: A torque converter management system includes a torque converter having a clutch and a torus. The torque converter management system includes memory hardware that stores instructions, that, when executed on data processing hardware of the system, cause the system to perform operations for protecting the torque converter. The operations include receiving torque converter temperature associated with the torque converter. The operations further include obtaining a torque converter protection schedule including one or more torque converter protective action initiation threshold temperatures each having an associated torque converter protective action and determining whether the torque converter temperature(s) exceeds a first one of the torque converter protective action initiation threshold temperatures. When the first torque converter temperature exceeds the first one of the torque converter protective action initiation threshold temperatures, the system initiates a first torque converter protective action associated with the exceeded first torque converter protective action initiation threshold temperature.

Abstract: A method for controlling an inflatable airbag system in a motor vehicle having a seatbelt includes detecting a position of a vehicle occupant relative to an airbag suppression zone (ASZ). Electronic input signals are received from a sensor suite, including an occupant position signal and a seatbelt usage status signal. A restraint capacity setting of the airbag is adjusted in response to the electronic input signals such that corresponding restraint activation logic is executed by the controller based on whether the occupant is belted or unbelted. Different ASZs may be used for belted and unbelted occupants. A motor vehicle includes a vehicle body defining a vehicle interior, an airbag, a seatbelt, a sensor suite for detecting a position of an occupant relative to the ASZ, and a controller operable for controlling a restraint capacity setting and location of the ASZ in accordance with the method.

Abstract: An electronic control unit (ECU), or node, is configured to use a single key for generating requests from a security peripheral for a MAC. The security peripheral includes the stored shared key. The security peripheral may further include a policy enabling it to detect if a request from the V-ECU is valid, in which case it generates a MAC. The security peripheral is also used to store information in a MAC Generate Allow List (MGAL). In some embodiments, the receiving nodes in a network receive data based on a security peripheral's response to a transmit nodes requests for a MAC. The receiving nodes use this knowledge to avoid being spoofed.

Abstract: A tool steel comprises iron (Fe); carbon (C) in a range from 0.001 wt % to 0.1 wt %; copper (Cu) in a range from 0.2 wt % to 2.0 wt %; nickel (Ni) in a range from 3 wt % to 10 wt %; aluminum (Al) in a range from 0.5 wt % to 3 wt %; manganese (Mn) in a range from 0.2 wt % to 1.5 wt %; chromium (Cr) in a range from 0 to 1.5 wt %; molybdenum (Mo) in a range from 0 to 1.5 wt %; tungsten (W) in a range from 0 to 1.5 wt %; and niobium (Nb) in a range from 0 to 0.2 wt %. A transition layer is arranged on the steel substrate. Metal of the transition layer includes Ni in a range from 5 to 20 wt % copper in a range from 1 to 5 wt %. One of an oxide layer and an oxide/nitride layer is arranged on the transition layer.

Abstract: A system for providing information to a vehicle occupant of a vehicle includes an automated driving system, a first display configured to provide information to the vehicle occupant of the vehicle, and a controller in electrical communication with the automated driving system and the first display. The controller is programmed to identify a planned change in driving behavior initiated by the automated driving system. The controller is further programmed to identify a traffic sign interpretation error using the automated driving system. The controller is further programmed to notify the vehicle occupant using the first display in response to identifying at least one of: the planned change in driving behavior and the traffic sign interpretation error.

Abstract: A trailer backing assistance (TBA) application in a vehicle includes a vehicle attached to a trailer by a movable hitch. The TBA utilizes an HMI, sensors on the vehicle, a GPS system, and a remote computing system (RCS). A controller having a processor, memory, and input/output (I/O) communicates with the sensors, HMI, RCS and GPS via a V2I communications network. The memory stores the TBA which is executed by the processor. The TBA determines conditions have been satisfied, obtains and processes optical data from sensors and RCS, presents a vehicle environment view, prompts a vehicle operator for first and second inputs, calculates a current location of the vehicle, generates a planned path to a target location, presents an animation of the vehicle traversing the path, and continuously displays a live view of the trailer and hitch while actively adjusting on-screen instructions to guide the vehicle and trailer along the path.
