Title:
HYBRID AUTOMOBILE
Document Type and Number:
Japanese Patent JP2017001499
Kind Code:
A
Abstract:
PROBLEM TO BE SOLVED: To suppress deterioration of travel performance in relatively short time from starting turn-on of accelerator despite the substantially high power storage ratio of a battery.SOLUTION: Control includes: pre-determining a correlation among a start-time power-storage ratio SOCst of a battery, a change lower-limit voltage Vbminch thereof, and change time tch thereof and storing the correlation in ROM as a given map; setting a change lower-limit voltage Vbminch and change time tch using the given map and start-time power-storage ratio SOCst at starting turn-on of an accelerator (S120); switching a controlling-lower-limit voltage Vbmin from a common lower limit voltage Vbmincom to the change lower-limit voltage Vbminch (S130); and switching the controlling-lower-limit voltage Vbmin from the change lower-limit voltage Vbminch (S180) when the change time tch elapses from starting turn-of the accelerator (S150).SELECTED DRAWING: Figure 2
