Abstract: Method and device (1) for controlling an alternator (2) delivering an electrical current which supplies power to electrical consumers (4) in a motor vehicle equipped with an internal combustion engine and which recharges a battery (3), in which method and device, for each journey, the intensity of an excitation current (Ie) for the alternator is controlled as a function of a time profile Ie(t) constructed from a probable time profile (&OHgr;a (t)) of the rotary speeds of the alternator and from the current (Ic) absorbed by the consumers. Preferably, the time profile of the rotary speeds of the alternator is determined from data provided by a navigation device (7) optionally combined with a traffic density information receiver (7′).

Abstract: A control for a motor vehicle transmission automatically shifts transmission gears as a function of at least a driving pedal position and vehicle speed on the basis of shifting performance graphs stored in memory, and takes a load state of the motor vehicle and the driving style of the driver into account. A fuzzy logic controller with a rule base evaluates various signals characterizing driving states of the motor vehicle, and thereupon generates the following control signals: a first correcting signal characterizing the load state of the motor vehicle, and a second correcting signal characterizing the driving style, bringing about a switchover to corresponding shifting performance graphs; and an inhibit signal preventing shifting events that would produce a dynamically unfavorable driving state.
