<p>PROBLEM TO BE SOLVED: To prevent a defect such that a head lamp brightness varies, by providing a power supply equipment with an electric load which is supplied with constant power through a power supply stabilizing means connected to a generator or a battery. SOLUTION: A voltage setting equipment 12 of a power generation controlling means 2 uses as target voltages a first and a second adjusting voltage higher than the one required for supplying constant power to an electric load equipment 6 through a stabilizing power supply 5. When a running state detector 7 detects acceleration, engine driving torque is insufficient and therefore the voltage setting equipment 12 switches the adjusting voltage to the second one which is set lower than the first one and higher than the output voltage of the stabilizing power supply 5. Then, a regulator section 14 controls the power generation of a generator based on the adjusting voltage. Therefore, power supplied to the stabilizing power supply 5 from the generator 1 becomes low at the time of acceleration, but the stabilizing power supply 5 supplies constant voltage lower than the first and the second adjusting voltage to the second electric load equipment 6. By this method, a fault can be prevented.</p> |
