Abstract
An apparatus for controlling electric generation for vehicles for use in an electric generating apparatus for a vehicle having a battery comprising a generator and an electric generation display device comprises: a first comparator circuit for comparing a detection value of the battery voltage with a first reference control voltage so as to charge the battery appropriately; an electric generation display control circuit for driving the electric generation display device in response to an output signal of a second comparator circuit for comparing a detection value of an electric generation voltage of the generator with a second reference control voltage; a third comparator circuit for comparing the detection value of the electric generation voltage of the generator with a third reference control voltage which is higher than the second reference control voltage; and means for driving an exciter circuit of the generator which receives the output signals of the first and third comparator circuits and operates to drive the exciter circuit only in at least one of the cases where the detection value of the battery voltage is lower than the first reference control voltage and where the detection value of the electric generation voltage of the generator is lower than the third reference control voltage, respectively. The use of this electric generation control apparatus for vehicles makes it possible to prevent the electric generation display device from malfunctioning to display a state of no electric generation in spite of a continuing electric generating operation of the generator.
