Hybrid electric powertrain configurations with a ball variator continuously variable transmission used as a powersplit

Принадлежит: Dana Ltd

Regular torque split planetary gear trains for automotive hybrid powertrains are limited by the fixed ratio of the planetary gear train. A powertrain incorporating a continuously variable transmission using a torque split with variable ratios enables the powertrain to use the ideal operating lines (IOL) of the engine, electric motor and generator along with the high voltage battery charge/discharge paths, depending upon the mode of operation (charge sustain or charge deplete modes) of the hybrid powertrain. A powertrain further equipped with a hybrid supervisory controller that chooses the torque split and path of highest efficiency from engine to wheel, can operate at the best potential overall efficiency point in any mode and also provide torque variability, thereby leading to the best combination of powertrain performance and fuel efficiency. Embodiments of powertrain configurations that can improve the efficiency of hybrid vehicles are discussed herein.

Methods and systems for operating a clutch of an axle are provided. In one example, the clutch may be characterized in static or dynamic conditions. The clutch characterization may be a basis for subsequently operating the clutch during gearbox shifting. In particular, an amount of torque that is transferred via the clutch may be controlled or adjusted according to the clutch characterization.

A hierarchical control system and method for a tandem axle assembly (102) for a vehicle is provided. The hierarchical control system includes a controller at vehicle level, an actuator (104), a shift controller (124), and a sensor. The shift controller (124) is capable of placing the tandem axle assembly (102) in at least a first operating condition and a second operating condition using the actuator (104). In response to the sensor and an operating condition of at least one of a power source (108) and a transmission of a driveline (100) of the vehicle, the shift controller adjusts a manner of placing the tandem axle assembly (102) in at least one of the first operating condition and the second operating condition. The hierarchical control system facilitates performing a shifting procedure in an automatic manner or as desired by an operator of the vehicle without excessively increasing a cost and a complexity of the tandem axle assembly.

A vehicle driveline and a method for synchronizing a flywheel and the vehicle driveline are provided. The vehicle driveline includes a power source, a primary clutch drivingly engaged with the power source, a primary transmission drivingly engaged with the primary clutch, a secondary transmission drivingly engaged with one of a portion of the primary clutch and an input of the primary transmission, a controller in communication with the secondary transmission, and a flywheel drivingly engaged with the secondary transmission. The vehicle driveline facilitates a transfer of energy to and from the flywheel based on at least one of a state of charge of the flywheel, a power requirement of the vehicle driveline, and a state of operation of the power source.

A drive axle system for a vehicle drive train having a clutching device is provided. The drive axle system includes a first shaft, a planetary inter-axle differential, a first axle assembly, a second axle assembly, a first clutching device, and a second clutching device. The first axle assembly is drivingly engaged with a portion of the planetary inter-axle differential. The first clutching device divides one of a pair of output axles into first and second portions. The second clutching device selectively engages a driving gear of the second axle assembly with a portion of the planetary inter-axle differential.

A method of operating a drive axle system is provided. The method comprises the steps of rotating a first shaft, drivingly engaging a first axle assembly, drivingly engaging a second axle assembly, moving a second clutching device into a position to disengage a second driving gear of the second axle assembly, and moving a first clutching device into a position to disengage a first portion from a second portion of one of a second pair of output axles, thereby allowing the second driving gear to coast to a substantially non-moving state.
