    Abstract: A vehicle electrical-load limiting apparatus wherein the priority given over a plurality of electrical loads, for restricting the driving of the electrical loads mounted on a vehicle, is first decided in order of importance and the amount of drive restriction of each of the electrical loads is then determined based on the remaining capacity of a vehicle electric source, thereby restricting the driving of the electrical loads. A fuzzy inference is carried out by making use of membership functions corresponding to both (a) the deviation indicative of the difference between a standard value set for each electrical load attached to the vehicle and a value of an electrical load when now in use, and (b) the residual capacity of the electric source. Then, the amount of the drive restriction of each of the electrical loads is obtained from the result of the fuzzy inference. It is therefore possible to automatically determine to what degree the driving of the electrical loads should be restricted according to the degree of the residual capacity of the electric source.

    Abstract: A hybrid electric vehicle (HEV) and method of operation includes a thermal management system (TMS) that maintains optimal battery temperature operating ranges. The TMS includes a controller, heater, pump, and valves that control a flow rate of a convective fluid about the battery and other components. The TMS responds to battery temperature and differential signals, converting them into pump speed and heater signals utilizing a fuzzy logic multidimensional membership function (MF) that improves performance while reducing energy consumption by generating real-time, smoothed pulse width modulated (PWM) pump speed and heater signals. The MF capability requires less processing power than prior systems, which in turn enables improved response time to battery thermal and temperature rate changes during HEV operation. The MF utilizes embedded temperature and differential MFs that generate respective, real-time, tuned signal conversion factors, without the need for calibration look-up tables, to generate the PWM pump and heater control signals.
