1. The adjustment voltage of the voltage regulator is 1'tl"C.
The output of the engine and the engine are suppressed to reduce the engine load. When driving or decelerating, I raise the adjustment voltage so that it takes 11 minutes to charge the 7 Rari. However, if you adjust the voltage in this way, the power supply voltage will fluctuate rapidly, and the headlights will suddenly go from being bright to -1 dimmer, and the voltage will remain constant for a long time. If i1]+ <na-2 suddenly occurs while the battery is in a bad state, a large current will momentarily flow through the battery, which is not good for the life of the badge.

In view of the above points, an object of the present invention is to provide a control device for an on-vehicle generator that gradually changes the regulated voltage of the voltage regulator to eliminate sudden changes in the charging current of the battery IJ-3. do.

Below-1: The present invention will be explained in detail with reference to the embodiment shown in the drawings.

In FIG. 1, 1 is an engine mounted on a vehicle, and 2 and 3 are drive wheels 3. l +: 1 Generator driven by engine 1, 5 is an accelerator, 6 is an opening sensor that detects the opening of this accelerator, 7 is an opening judgment circuit, and when the opening of the accelerator is suddenly greater than the set opening When an acceleration state is detected, a Luher signal is generated. A rotation speed sensor 8 detects the engine rotation speed and generates a pulse signal corresponding to the frequency of the engine rotation speed. 9 is F-V strange 15! ! ``C2'' converts the pulse signal of this rotation speed sensor 8 into F-■ to generate a voltage corresponding to 10 rotations. 10 is a judgment circuit, which sets the O level when idling, and the ゛C level when not idling. Generates a rubel signal at a time 1
．． It is something to do. 11 is a NAND circuit, 12 is a control voltage generating circuit, 13 is a constant voltage circuit, 14 is a voltage regulator, 15 is a battery, and 16 is a Key Inno f-. The generator 4 includes a rectifier diode 41, a '1' IN machine f coil 42, an excitation coil 43, and a flywheel diode 4.
It is equipped with 4. Control voltage generation II! l: (812 is the transistor 121 and the resistor 122.123.124.
125 and 12G and a capacitor 124, and the control voltage formed by each resistor and capacitor is changed depending on the ON/OFF state of the transistor 121.

Particularly controlled by the charging and discharging action of the capacitor 124) eyes,
1 It is designed to switch gradually. Also, constant voltage circuit 13
is composed of a Zener diode 131 and a resistor 132, and generates a predetermined constant voltage by inputting the battery voltage. The voltage regulator 14 includes an output transistor L 41 which drives the excitation coil 43, a resistor 142, and a resistor BTL 43, 144 and 145, and adjusts the battery voltage to a target control voltage.

Next, the operation of the above configuration will be explained. The accelerator 5 of the engine 1 is operated according to the driver's will, thereby increasing or decreasing the rotational speed of the engine, thereby accelerating or decelerating the vehicle. Therefore, when the vehicle is suddenly accelerated as shown in FIG. 2, the opening determination circuit 7 generates a 0 level signal as shown in FIG. 2B. On the other hand, since the rotational speed at that time is higher than the idle rotational speed, the determination circuit 10 generates a level signal. Thereafter, when the rapid acceleration ends and the vehicle enters a slow acceleration or a steady state, the signal from the opening determination circuit 7 becomes a level. On the other hand, since the signal of the determination circuit 10 remains at the Lebel level, the NAND circuit 11 changes from the Lebel level to the O level level at that point. By the way, when the NAND circuit 11 is in the 1st, 1st and 2nd positions, the transistor 121 is ONL, and the control voltages at the three points are controlled by the resistors 123, 125, .
12 and others, it is at the first voltage determined by -(. Then, when the output of the NAND circuit 11 changes from 1 level to θ level, the transistor changes from ON to OFF, and charging of the capacitor 124 begins. As shown in Fig. 2E, the control voltage at point 1 gradually rises by 1, and eventually the resistance increases by 1.
22.123.125.126゛ (changed to the determined second electric ratio.

In addition, the voltage regulator 14 manually adjusts this control voltage and controls the output transistor 141 so that the battery voltage becomes equal to this control voltage using the comparator 142, and as a result, the generated voltage is reduced to 4 as shown in FIG. 2E. jli to the state
l will be controlled.

Summarize these things for each driving condition of the vehicle'CJ
] The result will be as shown in Figure 2. In other words, the generator is controlled to the first voltage when the vehicle is running at a constant speed and during rapid acceleration, while the generator is controlled to the second voltage when the vehicle is in steady state, deceleration, and acceleration. When changing the first voltage and the second voltage, the changes are made slowly.

Therefore, since the output current of the generator changes gradually, damage to the vane lily is less likely.

In FIG. 2, A indicates the operating state of the vehicle, B indicates the output state of the opening determination surface Ii & 7, C indicates the output state of the determination circuit 10, and D indicates the output state of the NAND circuit 11. , and E indicates the control voltage corresponding to point a in the control voltage generating circuit 12. This corresponds to the generated voltage of the generator.

In this embodiment, sudden acceleration is determined only by the circuit using the opening sensor 6, but the vehicle may change due to changes in the signal of this circuit sensor 6, changes in the rotational speed, changes in the intake air amount of the engine, etc. A sudden acceleration state may be determined.

Furthermore, in this embodiment, during idling and sudden acceleration, the power generation voltage is set to the first voltage, for example, 12V, so that the actual charging operation is stopped, and the vehicle generates power only when it is in steady state, deceleration, and gentle acceleration. voltage to the second voltage e.g. 1
It is set to 5V to perform the charging operation, but there is no fixed temperature in this, for example, it is possible to perform a charging operation to a certain extent when idling, and when the 11 cars are decelerating. A voltage higher than the voltage of ff52 may be applied as a control voltage to further strengthen the charging operation.

- As stated above, in the present invention, the voltage regulator's key 1/! When changing the 1% pressure, the change is made gradually, so the charging current will not change suddenly, and the brightness of lamps etc. will change, or the life of the battery 1 - 1 will be reduced to low F. can be prevented.
