US 4,362,983 A · Generation control system for vehicles

Abstract

A generation control apparatus for vehicles comprises a voltage regulator circuit for controlling the generation of power by a vehicle generator. The power is supplied to the voltage regulator circuit through a first circuit including an ignition switch and a second circuit not including the ignition switch. The supply of power through the second circuit is dependent upon the generating condition of the generator thus allowing the control of the power generation by means of the current flowing through a charge indicator even if the detection of the power generation is prevented. In this way, even if a fault such as a break occurs in the first circuit, the generating operation is maintained until the engine is turned off and the generator has stopped.

Dependent claims

A generation control apparatus for vehicles having a generator, a battery and an ignition switch, said apparatus comprising:

a voltage regulator circuit for controlling the generation of power by the generator;
a first circuit for supplying electric power from the battery to said voltage regulator circuit through the ignition switch;
a second circuit for supplying the electric power to said voltage regulator circuit without passing through said ignition switch;
means for producing a generation signal indicative of the generating condition of said generator;
a charge indicator connected to said battery through said ignition switch;
and
an energization control circuit for controlling the supply of said power through said second circuit in response to said generation signal and to a current flowing through said charge indicator when said ignition switch is turned on and when said charge indicator gives no indication of power generation.

A generation control apparatus for vehicles comprising:

a battery mounted on a vehicle;
a generator mounted on said vehicle and having a field winding and a current generating winding;
a voltage regulating means connected to said battery and said field winding for controlling a field current flowing through said field winding in response to a battery voltage;
an ignition switch connected between said battery and said voltage regulating means for supplying electric power to said voltage regulating means when said ignition switch is closed;
a charge indicator connected to said battery through said ignition switch;
an indication control means connected to said current generating winding and said charge indicator for energizing said charge indicator when the output from said current generating winding is below a predetermined value;
and
circuit means connected to and operated by said indication control means so that said circuit means is operated to supply the electric power from said battery to said voltage regulating means when the output supplied from said current generating winding to said indication control means exceeds said predetermined value, whereby when said voltage regulating means is not supplied with the electric power through said ignition switch because of a disconnection between said voltage regulating means and said battery, said voltage regulating means continues to regulate said field current.
