Document Type and Number:
WIPO Patent Application WO/2012/098743
Kind Code:
A1
Abstract:
The purpose of the present invention is to optimally assess whether to connect or disconnect the rotating shaft of an engine and the rotating shaft of an electric motor in a regenerating state during deceleration. The purpose is achieved by configuring a hybrid ECU (18) for performing a control procedure so that a calculation formula is stored for varying the cargo load for each of a plurality of patterns in advance and calculating the percentage improvement in fuel consumption from the engine speed and the requested torque when a hybrid automobile (1) has traveled for a predetermined time in a state in which the rotating shaft of the engine (10) and the rotating shaft of the electric motor (13) are connected to each other during deceleration of the automobile; the percentage improvement in fuel consumption is calculated on the basis of the formula as well as the engine speed and the requested torque when the hybrid automobile (1) has traveled for a predetermined time during deceleration; and electric power is regenerated in a state in which the rotating shaft of the engine (10) and the rotating shaft of the electric motor (13) are connected to each other when the percentage improvement in fuel consumption thus calculated satisfies a predetermined condition.
