Title:
ENGINE START CONTROL METHOD FOR HYBRID ELECTRIC POWERTRAIN
Document Type and Number:
Japanese Patent JP2012116470
Kind Code:
A
Abstract:

To start an internal combustion engine by a torque source other than an electric motor and power generator depending on circumstances.

There is provided a method for starting the internal combustion engine for a vehicle including a hybrid electric power train having the internal combustion engine, the power generator and a high voltage battery pack. An internal combustion engine start input signal is received. A load on the electric motor and generator is determined. The internal combustion engine receives torque transmitted from the electric motor and generator when the load on the motor and generator is below a predetermined load threshold. The internal combustion engine receives torque from an exogenous starting device when the load on the electric motor and generator is above the predetermined load threshold.
