Abstract: A high voltage battery case assembly for a vehicle includes a battery case having a plurality of walls at least partially defining a cavity configured to receive one or more high voltage battery modules, a sacrificial pocket formed on an exterior of the battery case and including a thin-walled section, and an attachment bracket configured to couple between the sacrificial pocket and a body of the vehicle. The thin-walled section is configured to intentionally break away from the sacrificial pocket when the attachment bracket receives an impact load of a predetermined energy level to thereby facilitate protecting the high voltage battery case assembly from the impact load.

Abstract: A control system for an electrified powertrain of a battery electric vehicle (BEV) includes an accelerator pedal and a controller configured to determine maximum and minimum values for driver pedal position based on a first position of the accelerator pedal indicative of a first driver pedal position, determine whether the accelerator pedal position remains constant relative to the first position, when the accelerator pedal position does not remain constant and moves to a second position indicative of a second driver pedal position, detect that driver pedal position is increasing when the second driver pedal position is greater than the first minimum value and setting the first maximum value to the second driver pedal position and detect decreasing driver pedal position when the second driver pedal position is less than the first maximum value and setting the minimum value to the second driver pedal position.
Abstract: In at least some implementations, a screen assembly, includes a screen, an internal structure, an isolating material and an actuator. The screen has an outer surface and an input area, and the internal structure is behind the outer surface and defines part of a chamber behind the input area. The isolating material is within the chamber, and the actuator is behind the screen and arranged to provide haptic output to the input area. The isolating material damps the haptic output to reduce transmission of the haptic output to portions of the screen outside of the input area.
Abstract: A skip fire control system for an engine of a vehicle includes a set of sensors configured to measure a set of operating parameters of the engine corresponding to a volumetric efficiency of the engine, a set of sub-systems having a set of operational states that affect transitions between different firing patterns/fractions of the engine, and a controller configured to, based on the set of operating parameters and the set of operational states of the set of sub-systems, determine a best firing pattern/fraction by taking into account losses or penalties to transition at least some of the set of operational states of the set of sub-systems to obtain a target firing pattern/fraction, and control the engine based on the target firing pattern/fraction to maximize an efficiency of the engine.
Abstract: A two-speed gearbox assembly for an electric drive vehicle includes a housing, a first planetary gear set configured to operably connect to an output of an electric motor to drive a first axle, the first planetary gear set including a first sun gear, a first carrier, and a first ring gear, a first clutch configured to selectively ground the first ring gear, and a second clutch configured to selectively ground the first carrier. A second planetary gear set is configured to operably connect to the output of the electric motor to drive a second axle, the second planetary gear set including a second sun gear, a second carrier, and a second ring gear. A third clutch is configured to selectively ground the second ring gear, and a fourth clutch is configured to selectively ground the second carrier. The first, second, third, and fourth clutches are independently controlled.
Abstract: A battery control system for a battery electric vehicle is configured to detect that a driver door of the vehicle has been opened and connect the battery system to an electrical system of the vehicle to power at least a cabin heater and defroster of the vehicle, detect a driver start request, determine whether a set of battery parameters satisfy a threshold indicative of the battery system being sufficiently conditioned for driving of the vehicle, and when the set of battery parameters satisfy the threshold, display, via the user interface, a first message indicating that the vehicle is ready to drive and allow the driver to drive the vehicle and driving is prevented.

Abstract: In at least some implementations, a powertrain assembly, includes a combustion engine arranged to propel a vehicle, an electric motor arranged to propel a vehicle, a transmission coupled to the combustion engine and having a transmission housing and an output, an exhaust assembly coupled to the combustion engine, a drivetrain component driven for rotation by the output, multiple wires connected to the electric motor, and a housing. The housing has a first housing part and a second housing part that are coupled together to define an interior between them. At least one of the first housing part and the second housing part is coupled to the transmission housing, the wires are received within the interior and the housing is received between the transmission housing and both a portion of the exhaust assembly and a portion of the drivetrain component.
