Abstract
Provided is an output control device for a generator, improving the startability of an engine by supplying sufficient voltage to a fuel supply system and an ignition system. In ST31, a crank angle [theta]clk is detected. In ST32, whether a piston of the engine is located at a compression top dead center or its vicinity or not is determined in accordance with the detected crank angle [theta]clk.

Here, boost rectifying circuit 44, FET drive unit 53, oscillator 54 and calculator 55 constitute generating voltage increasing apparatus 110; In addition, FET62～FET64 and control device 65 constitute power control unit 111.
The generating voltage step-up method of above-mentioned generating voltage increasing apparatus 110 below is described.Fig. 4 is that explanation is by the schematic diagram that relates to the generating voltage step-up method that generating voltage increasing apparatus of the present invention carries out.At first, connect main switch 13, for example, the electric weight of battery 21 is few, even when 12 engines that switch starting do not start yet, steps on ballistic kick treadle 25, and the beginning ballistic kick rotates alternating current generator 33 thus and begins generating.
And, carry out three phase full wave rectification by the alternating current of commutating circuit 44 that boost with 33 of alternating current generators, between output terminal part 97,98, export direct current.This VD is applied on oscillator 54 and the calculator 55 by main switch 13.
As the starting resistor V of above-mentioned voltage less than oscillator 54
1The time, step on the ballistic kick treadle continuously, continue with alternating current generator 33 generatings.Like this, engine speed, be that the rotating speed of alternating current generator increases, generating voltage rises gradually, reaches the starting voltage V of oscillator 54 finally
1(cell voltage of this moment equals V
1), the result, oscillator 54 begins to take place oscillating impulse Pb.
As a result, oscillating impulse Pb input FET drive unit 53, the identical rectangular wave drive signal Sd of interchange output frequency, phase place that FET drive unit 53 is higher than alternating current generator 33 with frequency imports each grid of FET45～FET50 respectively.Thus, at each actuating coil 33a ac high-voltage taking place, thereby should exchange full-wave rectification by diode 91～diode 96, and carry out smoothing with electric capacity 101, promptly carries out copped wave by oscillating impulse Pb at the commutating circuit 44 that boosts.
And, when rectification and level and smooth after direct voltage reach starting voltage V than oscillator 54
1The starting voltage V of high CPU55a
2(this moment, cell voltage equaled V
2) time, CPU55a makes oscillator 54 stop to take place oscillating impulse Pb to oscillator 54 input pulse stop signal Sp, begins to take place cpu burst Pc simultaneously.As a result, cpu burst Pc input FET drive unit 53 carries out copped wave at the commutating circuit 44 that boosts again, and output voltage between the output terminal part 97,98 further raises.
Output voltage between output terminal part 97,98 reaches assigned voltage V
3The time (this moment cell voltage equal V
3), CPU55a stops to take place cpu burst Pc.When boosted output voltages so, just can be when engine start to the control device 65 sufficiently high voltages of input so that the petrolift 27 of the feed system load that acts as a fuel and injector 28,16 actions of all-transistor formula ignition coil, just can improve the startability of engine.
At voltage V
2Make oscillator 54 stop to take place oscillating impulse Pb, at voltage V
3Making CPU55a stop to take place cpu burst Pc is because for example work as V
1=3V, V
2=6V, V
3During=8V, oscillator 54 is the highest at 6V～8V efficiency of movement at 3V～6V, CPU.
Fig. 5 is first curve chart that explanation relates to generating voltage step-up method of the present invention, and the cell voltage VB during engine start (when connecting battery and alternating current generator when engine start, the generating voltage of cell voltage and alternating current generator equates) is 0≤VB＜V
1(V for example
1=3V).In addition, the longitudinal axis of coordinate is represented cell voltage VB (unit is V), engine speed N (unit is rpm), ignition pulse signal, oscillating impulse generation signal, cpu burst generation signal, transverse axis express time T (unit: msec).
Oscillating impulse or cpu burst do not take place at oscillator or CPU in oscillating impulse generation signal and cpu burst generation signal indication when the L level, cpu burst takes place for oscillator generation oscillating impulse, CPU when the H level.At first, at time t
1Connect main switch, at time t
2Step on ballistic kick treadle, the startup of beginning ballistic kick.
Like this, engine speed N rises at leisure, and along with engine speed rises, cell voltage slowly raises owing to alternator generation, at time t
3Cell voltage reaches the starting voltage V of oscillator
1, oscillating impulse generation signal switches to connection (H level) from disconnecting (L level), and promptly oscillator begins to take place oscillating impulse.
Raise by this oscillating impulse generating voltage, and further increase, reach the starting voltage VB=V of CPU at cell voltage VB by the cell voltage VB of this generating voltage charging
2The time, oscillating impulse generation signal is for disconnecting (L level), and cpu burst generation signal becomes connections (H level) from disconnecting (L level) simultaneously, that is, and stop to take place the oscillating impulse while, and CPU begins to take place cpu burst.
When cpu burst generation signal was connection, the timer starting was stipulated time t be increased to elapsed time t since elapsed time t=0 promptly
sBetween when having detected ignition pulse signal, CPU55a is t at the appointed time
