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.

Abstract: An electronic phaser system configured for use in an engine system is provided. The electronic phaser system comprises an intake camshaft, an electronic phaser and an engine control module (ECM). The intake camshaft has a plurality of camshaft lobes. The electronic phaser couples a gearbox to the intake camshaft. The electronic phaser is configured to rotationally advance the intake camshaft an amount of crank degrees to a desired rotational position. The ECM targets a desired cranking compression ratio based on one of an engine stop request and an engine start request. The ECM converts the desired cranking compression ratio into a camshaft lobe centerline position and commands the electronic phaser to rotate the intake camshaft to the desired rotational position that satisfies the camshaft lobe centerline position to achieve the desired cranking compression ratio. The desired cranking compression ratio is between 5:1 and 6:1.
