Hybrid vehicle control apparatus
First Claim
1. A hybrid vehicle control apparatus applied to a hybrid vehicle which includes an internal combustion engine and a motor as drive sources of said hybrid vehicle, includes a storage battery for supplying electric power to said motor, and is configured to perform regenerative braking by using said motor, and charge said storage battery with electric power generated as a result of said regenerative braking and electric power generated by using output of said internal combustion engine,said hybrid vehicle control apparatus comprising a control portion which controls said internal combustion engine in such a manner that said storage battery is charged and a remaining capacity of said storage battery approaches a predetermined target remaining capacity,said control portion obtaining a planned travel route of said hybrid vehicle,in the case where a target downhill section is contained in said planned travel route, said control portion executing downhill control when said hybrid vehicle travels in a particular section of a section which extends to an end point of said target downhill section from a downhill control start point which is shifted back from a start point of said target downhill section by a predetermined distance,said particular section containing at least a section extending from said downhill control start point to the start point of said target downhill section, andsaid downhill control changing said predetermined target remaining capacity to a remaining capacity smaller as compared with the case where said hybrid vehicle travels in sections other than said particular section,wherein said control portion obtains traffic congestion information which represent a congestion section, andsaid control portion prohibits execution of said downhill control when said target downhill section contains one or more congestion sections and a total distance of said one or more congestion sections contained in said target downhill section is greater than a predetermined distance threshold.

Abstract
A control apparatus for a hybrid vehicle including an internal combustion engine, a motor, and a storage battery and configured to charge the storage battery with electric power generated as a result of regenerative braking and electric power generated by using output of the engine. When a planned travel route of the vehicle includes a downhill section, the control apparatus executes a downhill control which decreases the remaining capacity of the storage battery before the vehicle enters the downhill section. In addition, when the downhill section includes a congestion section and the total distance of the congestion section is greater than a predetermined threshold, the control apparatus does not execute the downhill control.
