Altitude Compensation for Internal Combustion Engine

In order to address turbo lag at altitude, a vehicle boosts output torque of an internal combustion engine with electric motor torque generated from a battery. The residual charge of the battery is increased at altitude to provide a sufficient reserve for the corresponding increase in turbo lag. The...

More Information
Summary:In order to address turbo lag at altitude, a vehicle boosts output torque of an internal combustion engine with electric motor torque generated from a battery. The residual charge of the battery is increased at altitude to provide a sufficient reserve for the corresponding increase in turbo lag. The invention is typically applied to a parallel hybrid vehicle.
