摘要： Systems and methods are shown for estimating an available amount of acceleration available to a vehicle. In one example, a method for a controller of a vehicle comprises displaying an estimated available acceleration of the vehicle at a current speed of the vehicle in an in-cabin display of the vehicle, the estimated available acceleration estimated based on a performance characteristic of a power source of the vehicle and a model of an interaction of the vehicle with an environment of the vehicle. The power source may include one or both of an internal combustion engine and an electric machine.

摘要： Methods and systems are shown lubricating a cylindrical bore. In one example, a lubrication system comprises a piston-shaped bore lubricator with a plunger portion including a soft, porous material arranged in an external groove at a distal end of the plunger portion, the groove including holes through which a lubricant is ejected into the soft, porous material as the plunger portion is positioned in a bore. A proximal end of the piston-shaped plunger includes threads for coupling a squeezable lubricant source bottle, where the lubricant is ejected through the felt via an actuation of the squeezable bottle, or by gravity, or via a different kind of dispenser. An outside diameter of the piston may be adjusted to fit an interior diameter of the bore, and a size of the holes may be adjusted to increase or decrease a flow rate of the lubricant.

摘要： Methods and systems for an electric machine. The electric machine includes, in one example, a stator with end windings and a stator core and a cooling assembly with a spray ring that is directly coupled to an axial face of the stator core. In the electric machine, the spray ring is configured to spray a coolant at the end windings and includes a first section that extends down the axial face of the stator core and a second section that extends axially away from the stator core.

摘要： Methods and systems are provided for an electric machine. In example, an electric machine includes a stator that electromagnetically interacts with a rotor during electric machine operation. The electric machine further includes a first gear coupled to or included in a rotor shaft, a spring assembly coupled to a first side of the rotor and exerting a first axial force on the rotor, and a second gear that meshes with the first gear and exerts a second axial force that is opposite the first axial force, where a magnitude of the second axial force corresponds to a rotor torque.

摘要： A park lock unit and method for operation of said unit are provided. In one example, the park lock unit includes a sliding assembly that engages and disengages a parking pawl from a toothed wheel and an electronic actuation assembly configured to engage the parking pawl with the toothed wheel when electric power provided to the electronic actuation assembly drops below a threshold value. The park lock unit further includes a manual release mechanism configured to disengage the parking pawl from the toothed wheel in response to operator input.

摘要： Systems and methods for a lockable electric axle are provided. The electric axle includes a first electric machine coupled to a first drive wheel via a first gear set. The electric axle further includes a second electric machine coupled to a second drive wheel via a second gear set, and a locking clutch designed to selectively lock the rotation of a first rotor shaft and a second rotor shaft in the first and second electric machines, respectively.

摘要： Systems and methods for electric motor cooling. The cooling system, in one example, includes a sealing ring coupled to or formed in a stator and including a flange that axially extends outward from an axial side of the stator. The cooling system further includes a first sealing sleeve with a first sealing interface that is formed between the sealing sleeve and a motor housing and a second sealing interface that is formed between the sealing sleeve and the flange, where a cavity is formed between the sealing sleeve and the sealing ring in which a stator end winding is at least partially immersed in a coolant.
