Control device for hybrid vehicle
First Claim
1. A control device for a hybrid vehicle having an engine and a motor for driving said vehicle, and a battery device storing electrical energy converted, by said motor, from a part of the output of said engine or the kinetic energy of said vehicle, said control device comprising:
- a control pattern setting section for classifying a state of charge of said battery device into predetermined zones and for setting a specific control pattern for each of said predetermined zones;
a state of charge calculating section for calculating the state of charge of said battery device and calculating a use-permission zone with respect to the state of charge;
an assist amount setting section for setting an amount of power assist provided by said motor for assisting the output of said engine depending on said control pattern set by said control pattern setting section; and
an assist amount correcting section for correcting the amount of power assist in accordance with the width of said use-permission zone calculated by said state of charge calculating section.

Abstract
A control device for a hybrid vehicle which enables an appropriate electrical control based on the usable electrical energy stored in the battery device. In this control device, in step S357, in which it is determined whether the value of an energy storage zone B flag F_ ESZONEB is “1”. When the result of the determination is “Yes”, the operation proceeds to step S358. In step in step S358, the WOT assist amount lowest coefficient KQBWOASTL, which increases as the use-permission zone PECAPFIB of the state of charge SOC increases, is retrieved from a table. In step in step S359, the WOT assist amount coefficient,KQBWOAST, which increases from the lowest table value KQBWOASTL to a predetermined highest value as the state of charge SOC increases, is retrieved from a table, and a value obtained by multiplying the WOT assist command WOTAST and the WOT assist amount coefficient KQBWOAST retrieved from the table is newly set as the WOT assist command WOTAST.
