Problems solved by technology

However, there are various limitations associated with the use of this method, for example, external conditions (e.g., high altitude) can prevent the engine from producing the desired torque reserve, which can reduce the overall effectiveness of the torque hole filling strategy

Embodiment Construction

[0025] As required, specific embodiments of the claimed subject matter are disclosed herein; however, it should be understood that the disclosed embodiments are merely examples that may be embodied in various and alternative forms. The figures are not necessarily to scale; some features may be exaggerated or minimized to show details of particular components. Therefore, specific structural and functional details disclosed herein are not to be interpreted as limiting, but merely as a representative basis for teaching one skilled in the art to variously employ embodiments of the claimed subject matter.

[0026] Vehicle manufacturers are improving powertrains and drivetrains for hybrid vehicles to meet demands for increased fuel efficiency and lower emissions. One such approach to improvement may be referred to as a Modular Hybrid Transmission (MHT) vehicle design. In an MHT vehicle, a traction motor is disposed between the automatic transmission and the engine. The engine is s...

Abstract

The invention discloses a hybrid vehicle and a method for controlling the hybrid vehicle. A system and method for reducing torque disturbances during a shift event of a hybrid vehicle having an engine selectively coupled to a traction motor and an automatic transmission based on measured The transmission input torque controls or compensates for actual transmission input shaft torque by controlling a torque source such as a traction motor. The systems and methods may include an engine, a transmission, a traction motor positioned between the engine and the transmission, and a controller, the engine being selectively coupled to the electric motor and the transmission through a disconnect clutch, the controller being configured to control Motor torque such that the actual transmission input shaft torque reaches the target transmission input shaft torque.

Description

[0001] This application claims the benefit of U.S. Provisional Application No. 61 / 643,900, filed May 7, 2012, and claims priority to U.S. Application No. 13 / 834,976, filed March 15, 2013, the publications of both applications It is fully incorporated herein by reference. technical field [0002] The present disclosure relates to shift control of a hybrid vehicle having an engine selectively coupled to a traction motor and an automatic transmission. Background technique [0003] Multi-speed automatic transmissions in the powertrain of a motor vehicle utilize multiple friction elements to effectuate automatic gear ratio shifting. Often these friction elements may be described as torque building elements, although more commonly they are referred to as clutches or brakes. Friction elements establish a power flow path from a torque source, such as an internal combustion engine or a traction motor, to the vehicle's traction wheels. During vehicle acceleration, as a given acceler...
