Abstract:
1. A hybrid vehicle control system characterized in that in a storage battery control system for a hybrid vehicle comprises a plurality of storage batteries connected in parallel for supplying power to electric loads including a drive motor in said hybrid vehicle, allowable charge state range setting means for setting an allowable charge state range for said storage batteries, charge and discharge control means for controlling charge and discharge between said storage batteries and said electric loads in said vehicle within said allowable charge state range, storage battery abnormality detecting means for detecting an abnormality in said storage batteries, a plurality of switching means for connecting or separating said plurality of storage batteries respectively from said electric loads in said vehicle, and faulty storage battery separating means for, when said storage battery abnormality detecting means detects an abnormality in any of said storage batteries connected in parallel, for separating said switching means corresponding to said faulty storage battery, wherein allowable charge state range changing means changes high said allowable charge state range of said storage batteries preset in said allowable charge state range setting means so that the charge and discharge of remaining storage batteries is controlled within an allowable charge state range which is higher than said allowable charge state range of said storage batteries preset in said allowable charge state range setting means when separating said faulty storage battery is installed.
