Hybrid vehicle control apparatus

A vehicle drive transmission system comprising:

• an internal combustion engine;
• an electric motor that is mechanically independent from said engine;
• front and rear wheels with at least one of said front and rear wheels being an engine driven wheel driven by said internal combustion engine and at least one of said front and rear wheels being a non-engine driven wheel driven by said electric motor;
• and
• a hybrid vehicle control apparatus including
• a target motor torque setting section configured to set a target drive torque of said electric motor;
• a motor output limit determining section configured to determine if said target drive torque of said electric motor reaches an output limit of said electric motor under current operating conditions;
• and
• a torque increasing section configured to increase drive torque to said engine driven wheel when it is determined that the target drive torque of the electric motor reaches the output limit of the electric motor.

A hybrid vehicle control apparatus for a vehicle having front and rear wheels with at least one of the front and rear wheels being an engine driven wheel driven by an internal combustion engine and at least one of the front and rear wheels being a non-engine driven wheel driven by an electric motor that is mechanically independent from the engine, said hybrid vehicle control apparatus comprising:

• a target motor torque setting means for setting a target drive torque of the electric motor;
• a motor output limit determining means for determining determine if said target drive torque of the electric motor reaches an output limit of the electric motor under current operating conditions;
• and
• a torque increasing means for increasing drive torque to the engine driven wheel when it is determined that said target drive torque of the electric motor reaches said output limit of the electric motor.
