Problems solved by technology

[0004] A problem with MHT vehicles is that without the engine, the electric motor may not be able to provide the requested extra torque
Using an electric motor to start the engine requires a portion of the electric motor torque to be used for engine restart, further slowing or delaying vehicle start

Embodiment Construction

[0023] A detailed description of illustrated embodiments of the invention is provided below. The disclosed embodiments are exemplary of the invention that may be embodied in various and alternative forms. The drawings are not necessarily drawn to scale. Some features may be exaggerated or minimized to show details of specific components. Specific structural and functional details disclosed in this application are not to be interpreted as limiting, but merely as a representative basis for teaching one skilled in the art how to practice the invention.

[0024] refer to Figure 1A and Figure 1B , shows the modular hybrid powertrain 10 in schematic form. The engine 12 is operatively connected to a starter 14 that is used to crank the engine 12 when additional torque is required. The electric machine 16 or electric machines are operatively connected to the driveline 18 . A disconnect clutch 20 is arranged between the engine 12 and the electric machine 16 in the drive train 18...

Abstract

A hybrid power vehicle and an operation method thereof are provided. A disconnect clutch selectively separates an electric machine from a combustion engine. If a wide open throttle or high torque command is requested and the combustion engine is shut down, a 12 volt starter may be used to start the combustion engine while disconnected from the electric machine and all of the electric machine torque available may be used for traction.

Description

technical field [0001] The disclosure relates to a vehicle having an internal combustion engine and a traction motor that cooperate to provide torque to drive the vehicle and a control algorithm for starting the engine using either the starter motor or the traction motor. Background technique [0002] Vehicle manufacturers are developing hybrid vehicles to meet the demand for more fuel-efficient vehicles. One configuration of hybrid vehicles may be referred to as a modular hybrid drivetrain (MHT) vehicle design. In an MHT vehicle, the electric motor sits between the traditional multi-speed automatic transmission and the engine. The electric motor is attached to the transmission impeller or input shaft. The engine is selectively disengaged from the transmission using a specific "disconnect clutch". The disconnect clutch allows the vehicle to be driven in an electric-only mode, in a hybrid mode where the vehicle is propelled by both the electric motor and the engine, or in ...
