568981 V. Description of the invention (1) [Technical field to which the invention belongs] The present invention belongs to a vehicle engine starting device. The use of the engine to start the engine is particularly suitable for using the engine to automatically stop and start the vehicle. It can cooperate with a predetermined stop while the vehicle is running. The condition restarts in accordance with the scheduled starting operation after stopping. T stop, minute [known technique] When the engine starts, the starter motor starts to drive and the ignition device also ignites. Therefore, if the engine starts to rotate and its revolution is very low, the explosive force will cause the piston to reach the top dead center. Press it back, in addition to increasing the load on the starter motor and generating noise. This type is now called "Catching." In order to reduce the pressure explosion noise generated when the engine is started, for example, in Japanese Patent Laid-Open No. 60-1 87766 or Shikai Hei 2-1473, a forest device is proposed in which the number of engine revolutions reaches a predetermined number of revolutions. Technology of ignition action. More than one person [Problem to be solved by the invention] The aforementioned conventional technology starts counting the rotation number when a starting operation is detected, and allows the ignition device to operate when the number of engine rotations exceeds a predetermined value. Here, since the conventional technology is based on the premise that the engine is often started from a stopped state, the number of engine revolutions is gradually increased by the rotation of the starter motor. Therefore, if the measured engine rotation speed is above a predetermined value, the actual engine rotation speed at the subsequent actual ignition timing is often above the predetermined value, which can effectively prevent the occurrence of pressure explosion. In contrast, the stopping process of the running engine when it reaches the stopped state C: \ 2D-CODE \ 90-10 \ 90120091.ptd Page 6 V.

This switching element is intermittently controlled with a predetermined cycle and total efficiency (Duty) ratio to control the additional voltage of the headlight 169 substantially. That is, so-called chopping control is used. FIGS. 9 to 12 are block diagrams showing the functional structure of the main control mechanism 16 (its 2 ^ 2, its 3, its 4).

And if the "Stop & Start Mode", the idling signal changes from " qff " to " ON " (condition 3 is satisfied), then the action mode signal will shift from " h " bit f to " L " bit And the operation mode changes from "Stop & Start Mode" to "Start & Idle SW Mode". Furthermore, whether in the "Stop & Start" or "Start & Idling Sw Mode", if the main SW173 is interrupted (condition 4 is established), it will be in the "OFF" state. Returning to FIG. 9, the starter relay control unit 400 starts the starter relay 162 under predetermined conditions in accordance with the aforementioned operation modes. The detection signal of the pulser 153 is input to the determination unit 401 below the crank rotation number ^ and the determination unit 407 below the idle rotation number. When the number of crank revolutions is less than the predetermined number of crank revolutions (for example, 600 pm) or less, the signal "jj" is output. The number of idle revolutions determination means 4 07 When the number of engine rotations is less than a predetermined number of idling rotations (for example, 12 00 rpm), the output number of the "J {" level is output. ° AND circuit 402 outputs the logical product of the following signals, that is, crank rotation The output signal of the judgment unit 401 below, the state signal of the stop switch 259 and the state of the switch 258 are §§ numbers. The AND circuit 404 outputs a logical product of the following ^ 's, that is, the output signal of the judgment unit 407 below the idle rotation number.

The detection signal of 257a and the status signal of the riding switch "^. 4 Π: 4 03 The logical product of the following signals, namely the above-mentioned and circuit, the logical product of each 4th number, that is, the above-mentioned AND circuit 404 gives φ Signal and operation mode signal s301. The OR circuit 406 outputs the logical sum of the foregoing AND circuits 403, 405 as the start signal sin. The 5in extension portion 407 of the start operation is determined by the pulse width of the start signal sin in If the base time is short, it is extended above the reference time and output to the starting relay 162.% The starting signal S in extension section 407 contains the following two items: 1) Multiplexer 40 7a, detection The aforementioned start signal sin is outputted as a single-shot pulse signal, 2) the OR circuit 4 07b, and a logical sum of the aforementioned start signal sin and the output signal of the multiplexer 407a is output as the start signal sout. The aforementioned multiplexer 40 7a can arbitrarily extend the pulse width of its output pulse in accordance with the resistance value of the variable resistor. ^^ Fig. 18 is a timing chart showing the operation of the aforementioned start signal sin extension 407, multiplexing vibration Setting of the variable resistance of the 407a, The pulse width of the output pulse can be set to 0.6 seconds regardless of the pulse width t on of the start signal S iη. Therefore, even if the period of time when the start switch 258 is 0N is shorter than 0.6 seconds, the Dott vibrator 407a The output pulse amplitude is still 0.6 seconds. In addition, the OR circuit 4 0 7b outputs the logical sum of the output pulse of the multiplexer 407a and the start signal S in ', so the output signal S out of the start signal extension section 407, if the start signal If the pulse width t 〇n of S out is less than 0.6 seconds, then it will be 0 · 6 seconds'.

Furthermore, in the above-mentioned conventional embodiment, the starting signal is extended to 0.06 seconds, but the present invention is not limited to this, and must be set to the most appropriate setting in accordance with the rotation speed or reduction ratio of the starter motor C. That is, as shown in FIG. 19, when the engine is stopped, the probability that the piston will stop in the compression operation just before reaching the compression top dead center (TDC) is very high. When the starter motor 49 is driven in this state when the lower engine is started, the engine ignites before the down-M shrinks the coffee, but before the lower-down compresses the TDC. Therefore, the starter motor 49 must rotate the engine at least when the piston reaches the next retracted TDC. However, when the piston is stopped near the aforementioned next compression tdc, if the piston is stopped, the increase of the explosion will act on the reverse direction and cause the crank shaft to reverse. Therefore, the extended time of the part 407 is best to be 纟 | heart ~: 1 ° long ^ _ take the right sigh as, to stop at the compressed TDC just: drive to exceed its next compressed TDC and down-press dirty The time required for the location. As described above, this embodiment is provided with a start signal extension section 407. Even if the start switch 258 is only put in for a period shorter than 0.6 seconds, the starter motor 49 will be at least = 0.6 seconds. As a result, pressure explosion at the start of the engine can be prevented and the engine starting noise can be reduced. Also according to this embodiment, as long as the acceleration grip is opened for a short period of time, the starter motor can be driven at the minimum required time to start the engine. For vehicles using automatic centrifugal clutches, the rider does not need to pay attention to the increase in the number of engine revolutions. The engine can be easily started with throttle operation.

Description of the invention (13) Furthermore, according to the above-mentioned starting relay control, the AND circuit 4 0 3 under "Starting & Idle SW Mode" is Effective state. Therefore, if the number of engine revolutions is less than the number of crank revolutions and the stop switch 259 is in the ⑽ state (during braking operation), the start switch 258 is turned on by the rider (the output of the AND circuit 402 becomes the " H " level ), That is, the starter relay 162 is turned on and the starter motor 49 is started. Also in the "Stop & Start Mode", the AND circuit 405 is in an effective state. Therefore, if the engine rotation is below idling and the riding switch 254 is ON (cyclist is riding on the seat cushion), the throttle is turned on (the output of the AND circuit 4 04 becomes the " η " level), That is, the starter relay 62 is turned on and the starter motor 49 is started. In the standby indicator control section 600 of FIG. Ο, a signal from the vehicle speed sensor 255 is input to the vehicle speed zero judging section 601, and a signal of the "H" level is output when the vehicle speed is actually zero. The Ne judgment unit 602 obtains the number of engine rotations based on the detection signal of the pulse 153, and if it is below a predetermined value, it outputs a "H" level signal. The AND circuit 603 outputs the above-mentioned logical units of the judgment units 601 and 602. The AND circuit 604 of σ υ outputs the logical product of the output signal of the aforementioned AND circuit 603 and the inverted signal of the riding seat 254. The AND circuit 605 outputs a logical product of the output signal of the aforementioned AND circuit 603 and the output of the riding switch 254. If the output signal of the AND circuit 604 is at the "" η " level, the on / off control unit 606 is turned on, and if it is the " L " level, the on / off signal is generated.

568981 V. Description of the invention (14) The signal should be on and off. According to such a standby indicator control, as shown in FIG. 13, when the standby indicator 256 is stopped in the "Stop & Start Mode", the cyclist lights up if not riding, and then turns off when riding. Therefore, the cyclist can think that the standby indicator 2 $ 6 is on and off, even if the engine is stopped, as long as the acceleration grip is opened, it can be started immediately. The ignition control unit 700 of FIG. 10 starts, stops, or cancels (prohibits) the ignition operation under the conditions set by the ignition device 161 in the foregoing operation modes. The ignition start control section 701 responds to a predetermined vehicle start operation and turns on the start ignition signal S701 (" H " level), and allows the ignition device 161 to perform an ignition operation. The stop ignition control unit 702 responds to a predetermined vehicle stop condition and turns on the stop ignition signal S70 2 to cause the ignition device 1 61 to stop the ignition operation. The ignition prohibition control unit 7 03 sets the ignition stop signal S7 02 to ⑽ only during a predetermined period including the ignition timing for which a pressure explosion is expected, and prohibits the ignition device 1 61 from carrying out the state of the ignition start signal S70 1 described above. Ignition action. The operations of the control units 701, 702, and 703 will be described later with reference to the flowchart. The AND circuit 704 outputs a logical product of the aforementioned inverted signal of the start ignition signal S701 and the stop ignition signal S702. The AND circuit 705 outputs a logical product of the output signal of the aforementioned AND circuit 704 and the inverted signal of the ignition inhibit signal s 703. The OR circuit 7 06 outputs a logical sum of the output signal of the AND circuit 705 and the inverted signal of the operation mode signal S301. Therefore, in the "starting & idling SW mode" of this embodiment, the output of the OR circuit 706 is always at the "Η" level, and the ignition operation is always allowed. Relative to

Description of the Invention (15) In the "Stop & Start Mode", the ignition start signal S7〇1 is ⑽, and only when ignition is prohibited When the signal S703 is OFF, the ignition operation is allowed; otherwise, the ignition operation is prohibited. Fig. 20 is a flowchart showing the operation of starting the ignition control executed by the above-mentioned starting ignition control unit 701, which is repeatedly executed at a predetermined cycle. At step S201, it is judged whether the throttle handle is opened or not according to the output signal of the throttle switch 257a. If it is opened, it proceeds to step S203. In step §203, according to the output signal of the riding switch 254, it is determined whether the rider is in the riding state L2! The second has been ridden /, and in step S2 ° 5, the start ignition signal S701 becomes 0N (N level ). That is, the ignition of the ignition device 161 is allowed in the foregoing step S201. 'Even if it is judged that the throttle grip is not opened, it is determined in S202 that the vehicle speed is greater than the detection signal of the vehicle speed sensor 255, and then the process proceeds to step S203.

After that, in step S21 5 if the timer time is detected (the embodiment is 3 seconds) ), That is, in step S216, the ignition stop signal 37〇2 becomes ON (" H " level).

'The ignition operation of the ignition device 1 6 1 is stopped. FIG. 22 is a flowchart showing the operation of the prohibition system performed by the ignition prohibition control section 703 described above.

The foregoing operation of stopping the ignition control ignition device 16 is performed at step S221 in FIG. 22, and it is judged that the new stop is stopped if the stop condition at time t 0 in FIG. 23 is satisfied and the stop ignition signal S702 of the control unit 702 is ON, the operation will stop. As a result, the number of engine revolutions began to decrease. In the middle, for example, it is detected that the conditions for issuing the ignition stop signal S702 have been satisfied, and the process proceeds to step S222. Thereafter, as shown by the solid line A in FIG. 23, the engine rotation number Ne is detected at step S222 at time t 2 800 rpm, and the process proceeds to step S223. In step S223, the ignition stop signal S703 is set to ON (" H "level). As a result, the AND circuit 705 in the figure becomes a failure state. When the & start ^ formula is used, the engine rotation number Ne is 800 rpm Even if the ignition signal S701 is turned ON in response to the start operation, the ignition of the ignition device 61 will not be allowed. Furthermore, in this embodiment, if the number of engine revolutions is stopped before starting to 800 rpm during the stop process, During operation, the number of engine rotations drops to the speed at which the explosion occurs, and the next ignition time will come to rotate the engine. It is not necessary to prohibit the ignition of the ignition device 161. In step S224, according to the output signal of the pulser 153 If it is determined whether the ignition timing P2 is reached, the ignition prohibition count η is incremented at step g225. Furthermore, at this point, the ignition stop signal $ 7⑽ is οχ, the ignition of the ignition timing P2 is cancelled (prohibited) ). In step S226, it is judged whether the foregoing ignition prohibition count η has reached 3 times. If it is less than 3 times, it returns to step S224 to continue the ignition timing counting. Thereafter, the ignition timings P3, P The ignition of 4 is also cancelled. When each ignition timing is counted and the prohibited ignition count η reaches three times, the ignition prohibited signal S703 is changed to 0FF (" L "level) in step 3227. Thus, in the next ignition $ machine

Description of the invention (18) Because P5 allows the ignition action of the ignition device 161, if the start operation is detected and the ignition signal S7〇1 has already been sent. If the starter motor 49 has been driven, the engine is ignited and started. In step 3228, the ignition inhibit count n is reset. As described above, according to the present embodiment, when the stop condition is satisfied and the engine is stopped, if the engine drops below a predetermined number of revolutions, the ignition operation is cancelled only by the aforementioned number of times. Therefore, even if the engine is started before the engine is stopped, and the engine reaches the ignition position just before the top dead center at a low speed, the engine will not be ignited, so there will be no pressure explosion. In addition, when the number of engine rotations is measured based on the detection signal of the pulser 153, the measurement value may include errors due to engine differences, especially for engines with a small number of cylinders. For this reason, the measured engine rotation number can be displayed between the lower limit value shown by the broken line B in FIG. 23 and the upper limit value shown by the broken line c. However, after the number of engine revolutions has been reduced to 800 rpm in this embodiment, the ignition timing has been cancelled three times. If the polyline B is reduced to 800 rpm at time t 1, the subsequent three ignition timings PI, P2, P3. In addition, if the polyline C is reduced to 800 rpm at time t 3, the subsequent three ignition timings P3, P4, and P5 can be cancelled. Therefore, even if the measured value of the number of engine revolutions includes a measurement error, the ignition operation can be prohibited at the ignition timing P3 at which the explosion occurs, and the occurrence of the explosion can be reliably prevented. As described above, according to the ignition control unit 700 of this embodiment, as shown in FIG. 14, in the "starting & idling SW mode", the output of the OR circuit 706 is always at the " Η " level, and the ignition operation is always allowed. .

Description of the invention (19) In contrast, in the "Stop & start mode, the auto stop, if the cyclist has been riding 'vehicle stopped When the engine speed is greater than 0, that is, when the ignition is allowed = Η is turned on, or if the rider is detected to be riding, the vehicle is automatically stopped by the running engine, but if no riding is detected The person does not stop the ignition action, the engine will not stop automatically. The riding allows the ignition. Therefore, the riding switch 254 is not required to ask the rider, even if the vehicle is stopped / caused by the desire state to detect the rider. For the reason that has stopped, + the engine starts when it needs to move forward, J will not automatically stop calling and there will be no obstacles. Even if the riding switch is' according to this embodiment, the vehicle is measured from the rider to the rider. Riding is not forbidding the mind immediately: Bottom: Even if the check time (3 seconds in this embodiment) is forbidden again, the action is “pre-stop” or the rider ’s riding speed is almost zero, so he may return to Crossover: If the temporary opening is close to fully closed, the engine can continue to run The engine is stopped from the running state to the stopped state. The reason is that the ignition of the ignition device m is prohibited. Even if the engine starts before the engine is fully stopped, the engine is still in the lower ignition position. It will not be ignited. Furthermore, the above embodiment has explained that the ignition timing will be cancelled 3 times when the number of rotations of the engine is reduced to 800 rpm during the stop of the engine, but the present invention is not limited to this. When the number of revolutions from the engine dropped to 800 rpm

I I · 1 c- \ 2D-〇〇DE \ 9〇-l0 \ 9〇120091.ptd Page 24 568981 V. Description of the invention (20) The ignition timing is cancelled within the predetermined time. In this embodiment, the timing of cancelling the ignition has been explained three times. However, if the number of engine revolutions can be measured with high accuracy, the number of cancellations can be set to two or one. Conversely, if the number of engine revolutions cannot be adjusted to two For degree measurement, the number of cancellations can be set to 4 or more. Fig. 24 is a flowchart showing the operation of the other embodiment of the ignition prohibition control unit 703, and Fig. 25 is a diagram explaining the control content. In this embodiment, the stop condition is satisfied at time t 0 in FIG. 25. If the stop ignition signal S702 of the stop ignition control unit 702 is ON, in step S241 of FIG. 24, for example, the release of the stop ignition signal S702 is detected. It is determined that a new stop condition has been established, and the process proceeds to step S242. Thereafter, the number of engine revolutions Ne decreases, and at the time t 2 drops to the reference number of revolutions Nrefl (for example, 800 rpm), this is detected by step S242 and proceeds to step S243. In step S243, the ignition inhibit signal S703 is turned ON (" H " level). As a result, the AND circuit 705 in FIG. 10 becomes invalid. When the engine revolution number Ne is 800 rpm in the stop & start mode, even if the ignition signal S701 is turned ON in response to the start operation, the ignition device will not be allowed. Ignition action of 161. In addition, the starting condition is satisfied at time t 2 after the engine is stopped. If the start ignition signal 3701 of the aforementioned ignition start control section 701 is ⑽ and the starter motor 49 is driven at the same time, in step 3244, for example, the ignition start signal S701 is detected. When it is issued, it is judged that a new starting condition has been established, and the process proceeds to step S245. After that, the number of engine revolutions Ne increases and exceeds the reference number of revolutions at time t 3

When Nref2 (for example, 400 rpm), this is detected by step 3245 and the process proceeds to step S246. In step S246, the ignition inhibit signal 5703 is changed to 0FF (" L " level). As a result, in FIG. 10, the AND circuit 705 becomes invalid, and the ignition operation of the ignition device 161 is allowed. When the ignition timing is reached at time t4, the ignition operation is executed and the engine is started. ^. According to this embodiment, during the stop process of the engine reaching the stop state, the reference number of revolutions for the purpose of prohibiting ignition is Nrefl, and the reference number of revolutions for the purpose of prohibiting ignition during the process of starting the engine is Nref2. By making Nrefl higher than Nref2, the number of ignition cancellations (prohibitions) can be suppressed to a minimum, and at the same time, the occurrence of pressure explosion can be effectively prevented. Returning to FIG. 10, in the ignition knock control unit 2000, for each of the aforementioned kinematic operation modes, the ignition timing during acceleration is delayed longer than usual to implement control to prevent the occurrence of knock. In particular, in this embodiment, the retardation amount when the engine is stopped from the acceleration state when the engine is accelerating is larger than the retardation amount when the engine is from the rotating state to the normal acceleration state. In this way, the vehicle equipped with the engine stop and start control device can be completely Prevents knocking that occurs when acceleration is inherent. In the k-quasi-ignition timing determining unit 2007, functions of the engine rotation number Ne and the throttle opening degree 0 are registered in advance as a timing angle (deg) from TDC (compression top dead point) in the standard ignition timing. Figure 丨 6 is a graph showing the relationship between the number of engine revolutions Ne and the throttle opening 0 and the standard ignition timing in this embodiment, and it is 15 degrees ((1 "; timing) before the number of engine revolutions reaches 2500 revolutions, since After more than 2500 revolutions, the amount of timing is gradually increased in accordance with the number of engine revolutions Ne.

The Ne determination unit 201 sets the normal acceleration signal Saccl to, if the number of engine rotations Ne is 7000 rpm < Ne < 3,000 rpm, the H " level is 7000 rpm

Furthermore, the lower limit value of the number of engine revolutions ^ when the acceleration signal Sacc2 is generated at the time of launch (700 r pm in this embodiment) is preferably set to the number of engine revolutions. The acceleration judging unit 205 determines that the acceleration detection signal of the &amp; ^ &quot; H &quot; level has been performed if the change rate Δ of the throttle opening sound Θ detected by the throttle sensor 257 exceeds a predetermined value. The water temperature judging unit 206 judges the water temperature of the engine cooling water based on the detection signal of the water temperature sensor 155. When the water temperature exceeds a predetermined temperature (50 ° C in this embodiment), the output is &quot; II &quot; Level. The AND circuit 2 0 2 outputs the logical product of the inverted signals of the following signals, that is, the aforementioned normal acceleration signal Saccl, acceleration detection signal, water temperature judgment number &amp; and operation mode signal S301. The AND circuit 203 outputs ~ logical product 'of each of the following signals, i.e., the acceleration signal Sacc2, acceleration detection signal, water temperature determination signal, and operation mode signal S301 at the time of starting. Λ The ignition timing correction unit 204 during acceleration, if the output of each of the foregoing AND circuits 202 and 203 are at the "L" level, that is, when the vehicle is not in the acceleration state, the standard ignition timing determination unit 207 Ignition device 161 is notified of the determined standard ignition timing (Fig. 16). The ignition device 161 performs an ignition operation at the ignition timing notified by the ignition timing correction section 204 during acceleration. In addition, if the output signal of the AND circuit 202 is at the &quot; η &quot; level, that is, as shown in FIG. 14, in the "Starting & Idling Switch (SW) Mode", the number of engine rotations is 700 rpm <Ne &3000; rpm The cyclist performs acceleration operation and the water temperature exceeds a predetermined temperature (in this embodiment, 50 °), as shown by the broken line A in FIG. 17, the decision result of the standard ignition timing determination unit 207 is not limited, so that

This kind of ignition knock control can be set to pass from the middle speed rotation range * The delay amount is different when accelerating and when accelerating, and because the delay amount when accelerating is set to be greater than that from the medium-speed rotation range to the normal acceleration, it can prevent the explosion not only from the medium-speed rotation range to the normal acceleration. In the lamp control unit 800 before Fig. 11, the Ne judgment unit 801 is based on the pulse generator 153. Detect a signal to determine whether the number of engine revolutions is greater than a predetermined set number of revolutions (under full idle revolutions).

In this implementation, J, the total efficiency ratio is from 95% in 0.5 to 丨 seconds. Stepwise: to save power and maintain high commerciality. For this reason, Dayi ’s headlamp control, as shown in Figure 13, is especially "as it goes. As in the garden, in the" Start δ idling SW mode ", the headlamp is illuminated with the number of engine rotations Ne. Light / Dimmer, in the "Stop & Start Mode", the headlight lights up or down with the number of revolutions of the engine Ne, and the light is dimmed. Therefore, it is possible to maintain sufficient visibility of the oncoming vehicle and to suppress battery discharge when the vehicle is stopped. As a result, the amount of battery charging by the generator is reduced at the later start, and the acceleration performance at the start is improved by reducing the electrical load of the generator. In the side start control unit 900 in FIG. 11, a detection signal from the water temperature sensor 155 is input to the water temperature judging unit 901. This water temperature judging unit 901 outputs a signal of "H" level and turns off the side start relay 164 if the water temperature is higher than the i-th predetermined value (50 ° C in the present embodiment). If it is the second When the preset value (10 C in this embodiment) is less than or equal to, the signal of “L” level is output and the side start relay 164 is turned on. According to the side start control, the fuel becomes thicker when the water temperature is high, and when it is low, Automatic thinning. In the present embodiment, the hysteresis is set for the opening and closing temperature of the side start relay 1 64, which can prevent unnecessary opening and closing of the side start relay 1 64 which may occur near the critical temperature. .

During acceleration, the charge control unit 504 controls the rectifier regulator 167 in response to the aforementioned acceleration detection pulse signal, so that the charging voltage of the battery 168 decreases from a flat 14.5V to 12.0V. The charging control unit 504 during acceleration also starts a 6-second timer 504a in response to the acceleration detection pulse. When this timer expires, the number of engine revolutions Ne is greater than the set number of revolutions, or the throttle opening is reduced. That is, the charging limit is lifted and the charging voltage is returned from 12.0V to 14.5V. In the starting operation detection section 503, the detection signal of the vehicle speed sensor 255, the detection signal of the pulser 1 53, and the detection signal of the throttle sensor 2 5 7 are input, as shown in FIG. 14, if the vehicle speed is 0, When the throttle number is “less than the set number of revolutions (in this embodiment, 2500 rpm)”, it is determined that the acceleration detection pulse is generated when the throttle operation is started. When starting, the charging control unit 5 05 controls the rectifier regulator 1 6 7 when the above-mentioned starting detection pulse signal is detected, so that the charging voltage of the battery 16 8 is reduced from the normal 14.5 V to 12. 0 V.

Therefore, the mechanical load on the engine 200 by the generator 172 is reduced and the acceleration performance is improved. With the non-riding control unit 100, the timing of the engine may be &amp; t pi in the experience of the rider, exceptionally allowing the engine which is originally prohibited to start with the start switch 2 5 8.
