Kef3, after this condition is detected in step 525, in step S26, the ACG starter 1 is cut off and reset to the temporarily stopped flag F0ff. In step S27, the number of engine revolutions Ne and the number of engine revolutions are compared.

NreH, however, since the number of engine revolutions Ne is lower than the number of engine revolutions n initially, the process returns to step S16. Subsequently, although the above-mentioned step 316 is repeatedly performed to lower the processing, when the engine is not completely started, the engine rotation number Ne gradually decreases from the fastest time after the ACG starter i is stopped at the moment (case 2). Then, at time t8, the number of engine revolutions Ne decreases to the number of restarting revolutions%. When this condition is detected in step S22, then in step S23, the middle flag Foif is marked. … This time, in step S26, since the flag of temporarily stopping has been set, the process proceeds to step S24.

Description of the Invention (13) When the number of revolutions (Nrei2) is started, the ACG starter is restarted and then cranked again. Therefore, the excessive cranking can be prevented, and at the same time, the engine can be reliably started. Returning to FIG. 5, the power generation control unit 40 0 , Except for those with the usual control of power generation (electricity ~ voltage) Besides, it also has the function of increasing the power generation (hereinafter, referred to as "ACG energization control") by applying delayed-angle energization from the battery 2 to the above-mentioned ACG starter 1's phase coils of each phase. Current energization refers to a matter that the detection signal delay when the magnetic pole of the magnetized strip 33 detected by the rotor angle sensor 29 is changed corresponds to a predetermined electrical angle to charge the stator coil. However, in order to prevent the In the low rotation range, the engine rotation becomes unstable due to the sudden change in engine load caused by the operation of the above-mentioned current stabilizer 100, and the output voltage (battery voltage) of the full-wave rectifier bridge circuit 300 It is controlled within a predetermined voltage range below the steady-state voltage. In the power generation control unit 400, the engine rotation number determination unit 48, for example, detects the engine rotation number based on the detection signal of the ignition pulse generator 30, and the engine rotation If the number is a predetermined power generation control area, a retard angle command is provided to the driver 80. The driver 8 receiving the retard angle command 〇 reads the preset energized retard angle from the retard amount setting unit 49. The energizing load ratio is supplied to the driver 8 from the load ratio setting unit 47. The driver 80 detects the magnetic pole detection signal of the rotor angle sensor 29, that is, the sensor 29 detects When the magnetization band of the magnet ring 33 formed corresponding to the magnetic pole of the external rotor 60 is output, the signal rises to a conduction signal. Further, the start of the rise of the signal is delayed by a retardation angle corresponding to the amount of the energization retardation angle, and pw / The control signal is output to each FET of the full-wave rectifier bridge circuit 300. The battery voltage discriminating unit 46 controls the battery voltage Vb and a predetermined voltage to control the ore.

取 ΐ ri takes a large value Vmax and a minimum control voltage ν—compares the vehicle ^ and increases or decreases the energization load provided in the load ratio setting unit 47 according to the comparison result, and stores the battery voltage Vb in the above control range β. Also, if the battery voltage Vb reaches the maximum control voltage, ν Shipu ω, when the power and electric power i takes a large value Vmax, make the thunder i only decrease by a predetermined small value (for example, 〖%). (E.g., round 1 / G), if the minimum battery voltage Vb control voltage V mi η B temple, then energize | ^ ^ Ί ～ only the same small value rises from the oncoming beihe 0 Figure 8 shows the above power generation control unit The flowchart of the operation of 400 is for starting after the engine start control of the start control unit 500 has been completed. In step S41, it is determined whether the number of engine rotations exists in the power generation control area. The power generation control region is set, for example, within the range of 100 000 to 35 00 (^ 1) 111. If the number of engine rotations exists in the power generation control area, the process proceeds to step S42, and it is judged whether or not the flag 'g' indicating that the number of engine rotations exists in the power generation control area is set (= 1). If the flag is not set, go to step ‘FACG. In step S44, the energizing retardation amount aggagi is set to a predetermined value ACGAGL. The predetermined value ACGAGL can be appropriately set in advance. In this embodiment, for example, the electrical angle is 60 degrees. In the next step S45, the energizing load accuty is set to the initial value ACDUTY. The initial value ACDUTY may be appropriately set in advance. However, in this embodiment, it is set to, for example, 40%. When steps S43 to 345 are completed, the process proceeds to step S47. If the above step s42 is affirmative, skip steps S43 to S45 and go directly to step S47. If the number of engine revolutions does not exist in the power generation control area, the flag facg (= 0) is reset in step S46, and then the process proceeds to step S47.

Facg determines in step whether the battery voltage μ is at the maximum control voltage

Vma ^ c. 5V。 The maximum value of the control voltage Vmax is lower than the steady-state voltage, for example, is set to 13. 5V. If the battery voltage Vb is not higher than the maximum control voltage Vmax, it proceeds to step S49, and it is judged whether the battery voltage Vb is below the minimum control voltage Vm 1 η. The minimum value of the control voltage Vm | n is set to 13.0V, for example. · In step S49, if the battery voltage Vb is not below the minimum value of the control voltage, it is judged that it falls within the ACG energizing voltage range set to a value lower than the steady-state voltage of the current stabilizer, and the process proceeds to step S50. The retardation amount acgagl and the energizing load acduty perform ACG energization control. In step S48 ', if it is determined that the battery voltage Vb is above the maximum control voltage Vmax, the process proceeds to step S51, and the energizing load acduty is reduced by only a small value DDUTY. The minute value ddUTY is, for example, 1%. In addition, when it is judged in step §49 that the battery voltage Vb is below the minimum control voltage 丨 n, it proceeds to step S52, and the energizing load acduty is only increased by a small value DDUTY. After the processing in steps S51 and S52, the process proceeds to step S50. In addition, the above-mentioned minute value 时 when increasing and decreasing the energizing load acduty does not have to be the same value, and the above-mentioned minute DDUTY may be changed according to the ratio of the maximum value of the control voltage Vmax or the minimum value of the control voltage Vmin to the current value. On the other hand, if the flag is not set in step S47, the process proceeds to step S53 to stop the ACG power-on control because it is not in the power generation control area.

The "Angle energization control" is generally performed in response to the rotor angle sensor 29, and a change in the output (NS) is detected to supply current to the u, v, and w negative phases of the stator coil. On the other hand, In the case of angular energization control, when the rotation and the change of the positive and negative detection output (NS) of the sensor 29 are delayed, the angle d (= 60 degrees) is delayed and the current is supplied to the u, v, and w phases of the stator coil. In FIG. 9, the energization angle of the load chopping? Is 180 °. However, according to ^, the energization load provided by the setting unit 47 to the driver 80 can be changed to 180 ° at 180 °. In other words, the ACG starter j is a graph of the energized load set by parameters. The number of detected engine revolutions = 8 determines the energized load in response to the number of engine revolutions.... Normally, the voltage stabilizer that can't rotate can get stable electricity. This time, it can reduce the change of impact load when idling, etc .; force =. The change of the square rotation can stabilize the idling operation. 5, "recalled the control department 7 0 0 In still provide hunting startability of the engine, the engine is stopped immediately after the line reverse rotation of the crank shaft to return to a predetermined position. The handle f two judges two daggers 3 are based on the output signal of the rotor angle sensor 2 9 to divide the crank shaft 201 1-person into three stages of # 〇 ～ # 35 ， the pulse generator 30 produces a trip You corpse > recognize *, force u person Γ * ji-the pulse of 彳 & the point of maternity of childbirth as the reference series C, and the number # 0) to determine the current series. The number of stages passing time detection unit 74 is determined based on the multi-stage judging unit 73 described above.

Description of the invention (17) The time from the new stage to the judgment of the next stage is used to detect the passage time Atn of the stage. The reverse rotation control unit 75 generates a reverse rotation drive command based on the result determined by the multi-stage determination unit 73 and the passage time detected by the number of stages by the time detection unit 74. The duty ratio setting unit 72 dynamically controls the duty ratio of the gate voltage of each power FET supplied to the full-wave rectifier bridge circuit 300 based on the determination result of the multi-stage determination unit 73. The driver 80 supplies driving power of the full-wave rectifier bridge circuit 300 with driving pulses of the load ratio set above. Next, the operation of the swing-back control unit 700 will be described with reference to the flowchart of FIG. 11 and the operation explanatory diagram of FIG. 12. Figure I2 (a) shows the relationship between the crank torque (reverse rotation load) and crank angle required to reversely rotate the crankshaft 201, and the crank torque rises sharply before reaching the compression top dead center (during reverse rotation). Fig. 12 (&) shows the relationship between the crank angle and the progression, and Fig. 2 (c) shows the change in the angular velocity of the crank shaft during reverse rotation. In step S61 ', when it is detected that the engine is stopped, in steps S62 and S63, the current stage number determined by the multi-stage judging unit 73 is referred to. Here, if the number of stages is any of the number of stages # 〇 ~ # 11, the process proceeds to step S64. If the number of stages is any of the stages # 12 to # 32, the process proceeds to step S65. If it is other than the above (also In other words, if the number of stages is # 33 to # 35, the process proceeds to step S66. In steps S64 and S66, the duty ratio of the driving pulse is set to 70% in the duty ratio setting unit 72, and in step S65, it is set to 80%. ... As described in detail later, the dynamic control of such a load ratio is just moved to a point where the compression top dead center where the handle torque increases is substantially reduced, and the angular speed of the handle shaft 201 during reverse rotation is sufficiently reduced. At the same time, Angle system is used

Fast reverse rotation. D. In step S67, the drive 80 controls the full-wave rectification at the load ratio set above. Each power FET of the bridge circuit 3GG starts to perform reverse rotation. On the other hand, the energization time Atn of the number of steps #n passed in step ⑽t 'is measured by the above-mentioned number-of-pass detection section 74. In the step S69, in the reverse rotation control unit 75, it is determined whether or not the crank shaft is turned on, and the number # 0, that is, near the top dead center. If the crankshaft 201 has not passed the stage # 0, in step S71, the ratio of the passage time Δtn of the above-mentioned stage number # 11 that has just passed to the passage time △ "-1 of the stage that has passed before it is passed. [△ tn / zun-l] is compared with the reference value 訏 (4/3 in this embodiment). The above passage time ratio [△ ^ / △ 乜-丨] is returned if it is lower than the reference value Rref. The above step 562 belongs to the reverse rotation drive, and performs the above-mentioned processes repeatedly at this time. Here, the engine stop position, that is, the reverse rotation start position is shown as a curve a in FIG. 12 (c), The middle position of the compression top dead point of the next and next compression is closer to the compression top dead center of the next compression, that is, if it is the process from passing through the exhaust top dead center (when it is rotating forward) to the compression top dead center, ^ Make the ACG starter 1 drive in reverse rotation at a load ratio of 70%, and the crankshaft can also pass through the stage # 〇 (exhaust top dead point). Therefore, if this point is detected in step 369, the process proceeds to step S 70. It is determined whether the crank shaft 2 〇1 has reached the number of stages # 3 2. If it is determined that the crank shaft 201 has reached the number of stages # 32, in step S72, it is stopped due to the stop. Curve B in the reverse rotation power, and therefore, thereafter, stopped crankshaft inertial force and then reverse rotated. On the other hand, the reverse rotation start position based Shu FIG 2 (c) in the

It shows that the compression top dead center side of the previous and next compression top dead center, that is, the middle position of the force is closer to the previous rotation) The process of reaching the exhaust top dead center is / through compression top dead center (The positive load ratio is driven in reverse rotation. Therefore, as the ACG starter 1 shows 70%, if it reaches the stage # 0? As shown in Figure 12 (a), the angular velocity of the crank shaft 20 1 drops sharply., When 疋 and 仃 rise, the above-mentioned passing time ratio 'when judged' stops the above reverse spin $ in step S72, and 4/3 of re is stopped at almost the same time as the power is stopped at the nine-turn system. C * Backspin :: Earth: Review 'In the swing control of this embodiment, the angle after the engine stops: Ϊ?, Monitor whether the crank shaft passes the equivalent angle of the top dead point and the crank 疋 = 疋 is not lowered, if the crank When the shaft passes through the top dead point during reverse rotation, the reverse rotation energization ends immediately after the ^ ^, and the reverse rotation energization ends when the angular speed of the crank shaft decreases with the increase of the sa = rotation load. ^ This, ^ Inverse square 疋Regardless of the turning start position, you can return the crankshaft to the previous dead center position. (In the case of reverse rotation) The position where the compression reaction force is low. Sin Shrinking 'In the swing control of this embodiment, the rotor angle sensor based on the rotor angle (that is, the number of stages) of the ACG starter is detected. The 29 wheel is used to detect the angular velocity of the crankshaft 2 001, so there is no need to separately provide a sensor for producing the crankshaft 2 0 1 angle. # 知 【发明 的 结果】 According to the present invention, When the number of engine revolutions is reached when the engine reaches the starting state ^, the starter motor is automatically stopped to prevent the engine from turning unnecessarily after the engine is turned on. In addition, 'Because of the age of the engine based on the number of engine revolutions ^^
