Abstract
A method and apparatus for delivering power to a hybrid vehicle is disclosed. The apparatus includes an apparatus for delivering power to a hybrid vehicle, the hybrid vehicle including a powertrain having a power take-off coupling, the powertrain including an engine and a transmission. The apparatus includes an electric motor operable to generate a torque, the motor being coupled to transmit a starting torque through the power take-off of the powertrain for starting the engine.
Claims34
An apparatus for delivering power to a hybrid vehicle comprising:
- a powertrain comprising:
- an engine;
- a transmission coupled to the engine, the transmission comprising a torque converter;
- an electric motor coupleable to the powertrain, the motor being operable to generate a starting torque;
- and
- a power take-off for transmitting the starting torque through and bypassing the torque converter for starting the engine.
A method for delivering power in a hybrid vehicle comprising:
- causing an electric motor to generate a starting torque;
- and
- coupling the electric motor to a powertrain, the power train comprising an engine and a transmission;
- and
- transmitting at least a portion of the starting torque through a power take-off for starting the engine, wherein the starting torque bypasses a torque converter of the transmission.
An apparatus for transmitting a starting torque to a power-take off of a vehicle powertrain comprising:
- a power take-off clutch;
- an electric motor coupled to the power take-off clutch, the electric motor operable to generate the starting torque;
- and
- an actuator operable to engage the power take-off clutch to transmit the starting torque through the power take-off to an engine, wherein transmitting the starting torque through the power take-off bypasses a torque converter within a transmission of the powertrain.
