Title:
HYBRID-VEHICLE CONTROL APPARATUS
Document Type and Number:
Japanese Patent JP2017019396
Kind Code:
A
Abstract:
PROBLEM TO BE SOLVED: To control a revolution speed of an engine quickly even in a case of the chargeable capacity of a driving battery being small.SOLUTION: A hybrid vehicle 20 includes: an engine 22; a generator 28 for generating electricity by being driven by the engine 22; and a driving battery 32 being chargeable with power supplied from the generator 28. In a normal time, drive-required torque of the engine 22 is set as necessary generation torque in accordance with a required generation amount to the generator 28, and drive torque of the generator 28 is set at a value obtained by correcting the necessary generation torque with a correction value based on a difference between an actual revolution speed of the engine 22 and a target revolution speed thereof, thus controlling a revolution speed of the engine 22. Further, in a case where a chargeable capacity of the driving battery 32 is equal to or less than a first predetermined amount Px, and a difference ΔV between an actual revolution speed and the target revolution speed is equal to or more than a second predetermined value Vx, a fuel supply to the engine 22 is cut to reduce the revolution speed of the engine 22.SELECTED DRAWING: Figure 3
