More specifically, the control unit may be configured to determine a state of charge of a battery as a signal of a battery sensor and to minimize the driving load effect due to the alternator generation. The present invention relates to a junction box having a built-in power generation control function for a vehicle, which is installed in a junction box to control an alternator, thereby improving the acceleration performance and the fuel economy of the vehicle.

The vehicle power generator includes an alternator operated by a drive engine and a battery that accumulates generated electric energy.

The electricity remaining after producing the necessary electricity is charged to the battery (4).

Such a vehicle power generation device controls the alternator 8 that is rotated by the driving engine of the vehicle in the engine ECU 10.

That is, the engine ECU reduces the amount of power generated by the alternator when the drive load of the engine is high, and increases the amount of power generated by the alternator when the drive load of the engine is low, thereby efficiently controlling the power generation ratio according to the vehicle running.

As the alternator is efficiently controlled by the engine ECU, the acceleration performance of the vehicle is improved and the driving fuel efficiency is improved.

An alternator controller (not shown) is built in the engine ECU that controls the alternator.

The alternator controller, however, is difficult to apply when a vehicle has already been developed. That is, there is a problem in that program modification and circuit change of the engine ECU are very difficult, and thus, the vehicle ECU needs to be applied early in developing a vehicle.

In addition, the conventional alternator controller has a problem in that it is difficult to control the electric load consumed in the vehicle, and thus it is difficult to control the alternator generated power.

The present invention has been proposed to solve the above problems of the prior art, and an object of the present invention is to be easily installed in a vehicle that is not equipped with an alternator control unit.

Another object of the present invention is to provide a control unit that can control the alternator separately from the engine ECU so as to control the electric load consumed in the vehicle.

Still another object of the present invention is to allow the alternator drive to be selectively controlled to reduce the power consumption of the alternator while reducing the amount of electricity consumed in the vehicle when a large load is required in the engine.

Another object of the present invention is to increase the power generation of the alternator when the load of the engine is light, and to efficiently control the amount of power generated by vehicle acceleration and deceleration to improve vehicle acceleration performance and driving fuel efficiency.

Still another object of the present invention is to minimize the electric load inside the vehicle at the start of the vehicle in winter and to set the power generation rate of the alternator to be low so that the initial starting performance is improved.

The control unit of the junction box is characterized by controlling the alternator to operate at a low power generation rate before starting the engine and to operate normally after starting.

The controller of the junction box may determine the battery sensor as a normal state when the signal of the battery sensor recognized by the voltage sensor is within a preset tolerance.

The control unit of the junction box operates the relay and the power device according to the engine load signals of the battery sensor and the engine ECU to increase or decrease the current consumption in the vehicle, and to control the power generation of the alternator by interworking with the relay and the power device. It is done.

According to the present invention, by mounting the control unit for controlling the alternator in the junction box, it is possible to minimize the internal change of the vehicle and the design freedom is improved.

In addition, when the driving load is high according to the load signal of the battery sensor and the engine ECU, the power generation ratio of the alternator is lowered and current consumption in the vehicle is reduced, thereby improving vehicle driving performance.

In addition, when the drive load is low, the power generation ratio of the alternator is increased to solve the electric load inside the vehicle, thereby improving the fuel efficiency of the vehicle.

In addition, by lowering the power generation rate by controlling the start-up alternator, there is an effect that can improve the vehicle start in the winter.
