Among Fig. 9, action switching part 300 under the predetermined condition of idle running state of switch 253 and vehicle-state etc., with the pattern of master control set 160, switches in " starting and idle running SW pattern " and " stopping launch modes " any.

Idle running switch 253 state signal, be input to the action switching part 300 pattern signal carry-out part 301.When the state signal of idle running switch 253 is off state (restriction idle running), show " L " value; During for on-state (allowing idle running), show " H " value.Pattern signal carry-out part 301, reply the output signal of idle running switch 253, vehicle speed sensor 255 and cooling-water temperature sensor 155, output action mode signal S301, this pattern signal S301 is the pattern of master control set 160, is appointed as in " starting and idle running SW pattern " and " stopping launch modes " any.

Figure 15 is the figure of the pattern switching condition of pattern ground expression pattern signal carry-out part 301.After main switch 173 was connected, master control set 160 zero setting (condition 1 is set up) became " L " value with pattern signal S301, starting " starting and idle running SW pattern ".

In this " starting and idle running SW pattern ", if the above speed of a motor vehicle of predetermined speed (for example speed per hour 10km) is detected and water temperature is more than the predetermined temperature (temperature of prediction when for example warm-operation is over), and, idle running switch 253 is (condition 2 is set up) that disconnect, then make pattern signal S301 move on to " H " value, starting " stopping launch modes " from " L " value.

In " stopping launch modes ", when the idle running switch SW when being disconnected to connections (condition 3 set up), make pattern signal S301 move on to " L " value from " H " value, make pattern get back to " starting and the SW pattern that dallies " from " stopping launch modes ".In addition, no matter be " stopping launch modes " or " starting and idle running SW pattern ", as long as main SW disconnects (condition 4 is set up), all become the OFF state.

As shown in Figure 9, starter relay control device 400, according to above-mentioned each pattern, starting starter relay 162 under predetermined condition.The testing signal of Ne sensor 153 is input to following judging part 401 of pto rotation number and the following judging part 407 of idle running rotation number.The following judging part 401 of pto rotation number is judged as the engine revolution number and is predetermined pto rotation number (for example 600rpm) when following, exports " H " value signal.Idle running rotation number following judging part 407 when being judged as the engine revolution number for predetermined idle running rotation number (for example 1200rpm), is exported " H " value signal.

AND circuit 402, the theory of the state signal of the output signal of the following judging part 401 of outputting power output shaft rotation number, the state signal of stop switch 259, switch starter 258 is long-pending.AND circuit 404, the theory of the state signal of output signal, the testing signal of throttle switch 257a and the switch 254 of taking a seat of the following judging part 407 of output idle running is long-pending.

AND circuit 403, the theory of reverse signal of exporting the output signal of above-mentioned AND circuit 402 and pattern signal S301 is long-pending.AND circuit 405 is exported the output signal of above-mentioned AND circuit 404 and the theory of pattern signal S301 and is amassed.OR circuit 406 is exported with the theoretical of above-mentioned each AND circuit 403,405 with as activating signal Sin.When the pulse width of activating signal Sin than predetermined fiducial time in short-term, after activating signal extending portion 407 extends to it more than fiducial time, to starter relay 162 outputs.

Above-mentioned activating signal extending portion 407 comprises multi-vibrator 407a and OR circuit 407b.Above-mentioned multi-vibrator 407a detects above-mentioned activating signal Sin, output pulse signal once.Above-mentioned OR circuit 407b, with the output signal of above-mentioned activating signal Sin and multi-vibrator 407a theoretical and, as the activating signal Sout output after prolonging.Above-mentioned multi-vibrator 407a, according to variable-resistance resistance value, the pulse that can prolong its output pulse arbitrarily is wide.

Figure 18 is the time diagram of the action of the above-mentioned activating signal extending portion 407 of expression.The variable resistance of multi-vibrator 407a, the pulse width of its output pulse and the wide ton of pulse of activating signal Sin irrespectively are set at 0.6 second.Therefore, even switch starter 258 is only connected during than 0.6 second weak point, the output pulse of multi-vibrator 407a is wide also to be 0.6 second.

In addition, OR circuit 407b, the output pulse of output multivibrator 407a and the theory of activating signal Sin and, so the output signal Sout of activating signal extending portion 407 is, if the pulse width ton less than of activating signal Sout 0.6 second is 0.6 second; If the wide ton of the pulse of activating signal Sin is longer than 0.6 second, then be the signal of its pulse width.

In the foregoing description, be that activating signal is extended to 0.6 second, but the present invention is not limited thereto, can carry out optimal setting according to the rotational speed of starter motor 49 and reduction speed ratio etc.

That is, as shown in figure 19, when motor was stopped, its piston broke out in the preceding compression stroke of top dead center (TDC) in arrival, the probability height that stops.When engine start next time, during from this state-driven starter motor 49, before outburst TDC thereafter, motor misfires, just outburst before next time breaking out TDC.Therefore, starter motor 49 before piston arrives breaks out TDC next time, must make engine revolution at least.

But, near the above-mentioned moment of breaking out the TDC of piston arrives next time,, then break out load effect to reverse direction if starter motor 49 has stopped, crankshaft 12 is reversed, produce so-called back attack phenomenon.Therefore, the time expand of above-mentioned activating signal extending portion 407, preferably be set at such time:, be driven to the compression TDC that surpasses thereafter and the needed time of position of next compression TDC at the piston that outburst stops in front of the TDC.

As mentioned above, in the present embodiment, activating signal extending portion 407 is set, even 258 of switch starteies are connected during than 0.6 second weak point, starter motor 171 also can be driven 0.6 second at least.Therefore, the recoil when preventing engine start reduces the engine start sound.

In addition, according to present embodiment, even draw back throttle grip in the short time, because starter motor was driven in the time of the required minimum of engine start, so in the vehicle that adopts automatic centrifugal clutch, the driver needn't worry the rising of engine revolution number, can easily pass through throttle operation, make engine start.

In addition, according to above-mentioned starter relay control, in " starting and idle running switching mode ", AND circuit 403 becomes the state of energizing.Therefore, when the engine revolution number below the pto rotation number and stop switch 259 when being on-state (in the brake operating), if switch starter 258 is connected (output of AND circuit 402 becomes " H " value) by the driver, then starter relay 162 conductings, starter motor 171 startings.

In addition, in " stopping launch modes ", AND circuit 405 becomes the state of energizing.Therefore, below the engine revolution number is idle running, when the switch 254 of taking a seat is on-state (driver is positioned on the vehicle seat), if closure is performed fighting (AND circuit 404 is output as " H " value), then starter relay 162 conductings, starter motor 171 startings.

In the backup indicator control device 600 of Figure 10, the testing signal of vehicle speed sensor 255 is input to the speed of a motor vehicle zero judging part 601, if the speed of a motor vehicle is zero, then exports " H " value signal.The testing signal of Ne sensor 153 is input to Ne judging part 602, if the engine revolution number below predetermined value, is then exported " H " value signal.AND circuit 603 is exported the theory of the output signal of above-mentioned each judging part 601,602 and is amassed.

AND circuit 604 is exported the theory of the reverse signal of the output signal of above-mentioned AND circuit 603 and the switch 254 of taking a seat and is amassed.AND circuit 605 is exported the theory of the output of the output signal of above-mentioned AND circuit 603 and the switch 254 of taking a seat and is amassed.Bright lamp/flicker control device 606 when the output signal of AND circuit 604 is " H " value, sends lamp bright signal; If " L " when value then send flash signal.AND circuit 607 is exported the output signal of bright lamp/flicker control device 606 and the theory of pattern signal S301 and is amassed.Backup indicator 256 is replied lamp bright signal and bright lamp, replys flash signal and glimmers.

According to the control of such backup indicator, as shown in figure 13, during the parking of backup indicator 256 in " stopping launch modes ", if the driver is not sitting on the vehicle seat, with regard to bright lamp, if be sitting on the vehicle seat, just flicker.Therefore, the driver knows, if backup indicator 256 flickers even motor stops, just can being started immediately as long as draw back throttle grip.

The IGNITION CONTROL portion 700 of Figure 10 for above-mentioned each pattern, allows or forbids the igniting action of ignition control device 161 under predetermined condition.

The judging part 701 that travels according to the testing signal of vehicle speed sensor 255, judges whether vehicle is travelling state.If travelling state, the signal of output " H " value.OR circuit 706, output travel the output signal of judging part 701 and throttle switch 257a output signal theory and.The take a seat theory of output signal of the output signal of switch 254 and above-mentioned OR circuit 706 of AND circuit 707, output is long-pending.Therefore, the output of AND circuit 707, closure open or the speed of a motor vehicle greater than zero and driver when being sitting on the vehicle seat, become " H " value.

The take a seat theory of reverse signal of reverse signal, throttle switch 257a of the output signal of switch 254, the judging part 701 that travels of AND circuit 702, output is long-pending.Timer 703 is with the output of input signal delay scheduled time (being 3 seconds in the present embodiment) back.NAND circuit 705, the theory of the output signal of the above-mentioned AND circuit 702 of counter-rotating output and the output signal of timer 703 is long-pending.Therefore, the output of NAND circuit 705, closed throttle, the speed of a motor vehicle be zero and the driver be sitting in that state continuance became " L " value in the time of 3 seconds on the vehicle seat.

The travelling contact of diverter circuit 708 in the igniting action of ignition control device 161, is switched to NAND circuit 705 sides, in stopping, being switched to AND circuit 707 sides.OR circuit 709, to the theory of the reverse signal of the output of the reverse signal of the above-mentioned pattern signal S301 of ignition control device 161 output and diverter circuit 708 and.

According to the IGNITION CONTROL portion 700 of above-mentioned structure, as shown in figure 14, in " starting and idle running SW pattern ", because the output of OR circuit 709 is " H " value always, so, usual tolerable igniting.

And in " stopping launch modes ", when vehicle stops, when motor stops automatically, when the driver is sitting on the vehicle seat, closure open or the speed of a motor vehicle greater than zero the time, allow IGNITION CONTROL.When vehicle when travelling state has stopped, being sitting on the vehicle seat if detect the driver, then forbid IGNITION CONTROL, motor stops automatically.Be not sitting on the vehicle seat if detect the driver, then allow IGNITION CONTROL, motor does not stop automatically.

Therefore, though switch 254 goes wrong when taking a seat, the driver is sitting on the vehicle seat and detects not then, even vehicle stops from travelling state, motor does not stop automatically yet, so, the engine start when not needing to start.Therefore, whether be condition, allow in the self-drive system of motor if being sitting on the vehicle seat with the driver, even the switch 254 of taking a seat goes wrong, also can not influence and travel.

In addition,, when vehicle has stopped from travelling state, be sitting on the vehicle seat, also do not forbid IGNITION CONTROL immediately, but forbid after having passed through the scheduled time (being 3 seconds in the present embodiment) even detect the driver according to present embodiment.Therefore, at the parting of the ways temporarily stop or driver's seat to take the state speed of a motor vehicle at car be zero and the throttle opening U-shaped that is bordering on complete shut-down when turning round substantially, make engine start sustainably.

The ignition shock control device 200 of Figure 10 to above-mentioned each pattern, postpones the ignition timing when quickening than usual, prevents to knock.Especially in the present embodiment, motor from halted state quicken start to quicken the time retardation, retardation when being set at greater than motor from rotation status to common acceleration, like this, to the vehicle of the automatic stopping-starting device of motor is housed, can prevent intrinsic knocking when starting to quicken fully.

In the standard ignition determination section in period 207, registering standard ignition in advance, (this ignition timing is to count the function of Ne and throttle from advance angle angle (deg) and the engine revolution of TDC (outburst top dead center) period.Figure 16 is the figure that the engine revolution in the expression present embodiment is counted Ne and throttle and standard ignition relation in period.Before the engine revolution number does not reach 2500 commentaries on classics, be 15 degree (deg, advance angle), after changeing above 2500, count Ne correspondingly with engine revolution, the advance angle amount increases gradually.
