    摘要: A vehicle power generation control apparatus has a power supply circuit, a rotation detecting circuit, an exciting current detecting circuit, a torque detecting/maximum exciting current determining circuit, and an exciting current control circuit. The rotation detecting circuit detects a rotation speed of a generator (or vehicle alternator) and the exciting current detecting circuit detects an exciting current flowing through an exciting winding of the generator. The torque detecting/maximum exciting current determining circuit calculates a power generation torque of the generator based on the output voltage, the exciting current, the rotation speed, and calculates an inertia torque of the generator based on a change rate of the rotation speed. The exciting current control circuit suppresses the exciting current flowing through the exciting winding so that a change rate of a total sum of the generation torque and the inertia torque does not exceed a predetermined value, for example, during the idling condition.

    摘要: In a vehicle generator control which detects an abnormal operating condition of a generator of a vehicle, and includes a transistor which drives a charging lamp to emit a warning indication when such a condition is detected, with the value of a quantity indicative of the flow of current through the charging lamp drive transistor being compared with a reference value, and with the transistor being set in a non-conducting state if the reference value is exceeded, a succession of respectively decreasing reference values is periodically generated. A timing of an initial flow of current through the charging lamp is controlled to be synchronized with the start of such a succession, so that the peak value of an initial surge current which flows through the charging lamp drive transistor is compared with the highest reference value. Complete protection can thereby be established for the charging lamp drive transistor against a flow of short-circuit current which would exceed any of the reference values.
