Control system for electric power generating apparatus on hybrid vehicle
First Claim
1. A control system for controlling an electric power generating apparatus having an electric generator and mounted on a hybrid vehicle which has a propulsive electric motor powered by a battery and an internal combustion engine for actuating the electric generator to generate an electric power output to charge the battery, comprising:
- operating condition detecting means for detecting, from time to time, vehicle operating conditions including at least a charged and discharged condition of the battery and a vehicle speed of the hybrid vehicle;
fuzzy reasoning memory means for storing beforehand a membership function and a plurality of fuzzy rules to determine an operational amount for the electric generator from said vehicle operating conditions by way of fuzzy reasoning;
goodness-of-fit calculating means for determining goodnesses of fit of the respective fuzzy rules based on said membership function from said vehicle operating conditions detected by said operating condition detecting means;
generator operational amount calculating means for combining the goodnesses of fit of the respective fuzzy rules determined by said goodness-of-fit calculating means and determining an operational amount for the electric generator based on the combined goodnesses of fit; and
control means for controlling the electric power generating apparatus according to the operational amount for the electric generator determined by said generator operational amount calculating means.

Abstract
An electric power generating apparatus having an electric generator is mounted on a hybrid vehicle which has a propulsive electric motor powered by a battery and an internal combustion engine for actuating the electric generator to generate an electric power output to charge the battery. A goodness-of-fit calculator and a generator operational amount calculator determine an operational amount for the electric generator based on a membership function and fuzzy rules stored in a fuzzy reasoning memory according to fuzzy reasoning from vehicle operating conditions including a charged and discharged condition of the battery and a vehicle speed of the hybrid vehicle, detected by operating condition detectors.
