A light control apparatus for a vehicle is integrated with headlamp driving relays, a light sensor, a lighting switch which selects a manual mode or an automatic mode, and a control unit which controls the relays in accordance with the light sensor output when the lighting switch selects the automatic mode and turns on or off the headlamps. Two power source systems and two headlamp driving systems are provided. The signal level of a given terminal of the control unit is detected and is input to the microcomputer of the control unit. The microcomputer judges whether or not trouble has occurred by detecting a level difference. An alarm indication is given by a lamp or a buzzer if trouble is detected.

Light control apparatus for a vehicle

There is disclosed herein a generator control system for use in a power supply system for vehicles in which a battery and an engine-driven generator are connected in parallel with a load. The total load current fed to the load is detected and the generated voltage level is changed by performing field regulation for the generator in accordance with the detected value. Switching of the generated voltage level of the generator is controlled according to the state of the load applied so as to improve power generation efficiency. Certain parameters, such as battery state, engine speed, auto choke and load state, can be provided as an input or inputs to a voltage regulator for the generator.

Control system for engine-driven generator

An automatic light control apparatus for a vehicle comprises an external light detector for selectively turning on and turning off at least one of tail lamps, side marker lamps and head lamps of a vehicle in accordance with the detected external light. A further detector is provided for detecting the ON period of an illuminating light having a fluctuating light value (for example generated by an A.C. voltage source), and the lamps are further controlled in accordance with the detected ON period of the fluctuating light value in conjunction with the signals generated by the external light detector, for controlling the illumination of the lamps of the vehicle. A further detector may be provided for detecting an abrupt change in the illumination level, and for controlling the vehicle lamps further in accordance with the detected abrupt change.
