In body forward structure 11, such as handlebar 12 vicinity, right side is provided with for forcing the stop switch 24 making hereinafter described on-board engine stop.This stop switch 24 forms a part of forcing shut-down mechanism.Driver makes motor force to stop by the operation of carrying out pressing stop switch 24 in engine running via engine controlling unit 100 at once.

In addition, although indicate structural element 25,26 and 28 in FIG, because this structural element is not required structural element in the first embodiment, therefore represent with imaginary line, and their description is omitted.

Next, the structure of the engine controlling unit 100 in the cart shown in Fig. 1 is described.Fig. 2 is the block diagram of the electrical structure representing engine controlling unit 100.

The motor 30 being equipped on the cart 10 shown in Fig. 2 is such as spark-ignition gasoline engine.This motor 30 has at least one cylinder, and is provided with in this at least one cylinder for making the mixture combustion of air and the fuel (gasoline) transported via gas-entered passageway thus obtaining the firing chamber of power.The power obtained makes the output shaft of motor 30 rotate.The rotation of the output shaft of this motor 30 passes to the driving wheel of cart 10 via the speed changer of this cart 10, thus by making driving wheel rotate, cart 10 is travelled.

Motor 30 possesses: as the sparger 31 for the fuel supplying machine structure by coming firing chamber supply mixed gas (air-fuel mixture) to cylinder to gas-entered passageway or firing chamber burner oil; And as being used for lighting a fire to the mixed gas being supplied in this sparger 31 ignition mechanism 32 (spark coil, ignition spark plug etc.) of the ignition mechanism that makes it burn.In addition, be provided with in motor 30 and to the output shaft of this motor 30 is additional as when engine start initially rotates (being rotated by crank (cranking)) and make the starter 33 that motor 30 is rotated by crank.

Engine controlling unit 100 controls above-mentioned motor 30, and such as shown in Figure 2, possess ECU20, above-mentioned time showing portion 22, stop switch 24, diverter switch 25, vehicle speed sensor 35, throttle valve opening sensor (throttle position sensor) 36, front brake sensor 37 and rear brake sensor 38.This time showing portion 22, stop switch 24, vehicle speed sensor 35, throttle valve opening sensor 36, front brake sensor 37 and rear brake sensor 38 are connected with ECU20 in the mode that can communicate respectively.In addition, although illustrate structural element 25,26 and 28 in fig. 2, however due to these structural elements in the first embodiment and nonessential structural element, therefore carry out representing with imaginary line and their description is omitted.

ECU20 is such as possessing the electric control device of well-known microcomputer.ECU20 implements the various engine control process of the fuel injection amount control treatment based on sparger 31, the IGNITION CONTROL process based on ignition mechanism 32 etc. and the drived control process of starter 33 according to the testing result and various switch (comprising above-mentioned switch 24) etc. of the various sensors (comprising the sensor 35 ~ 38) being arranged at master control set 100.

Vehicle speed sensor 35 has the function detecting the speed of cart 10 and the testing signal of the speed representing the cart 10 detected is sent to ECU20.Throttle valve opening sensor 36 has the function detected the aperture being arranged at the gas-entered passageway of above-mentioned motor 30 the throttle valve valve TV in the throttle valve adjusted for the delivery volume of the air in the firing chamber of subtend cylinder.Namely, this throttle valve valve TV is connected with throttle valve handle 14, the aperture of throttle valve valve TV changes according to the direction of operating of the throttle valve handle 14 based on driver and operation amount, the operation information of throttle valve valve TV that throttle valve opening sensor 36 will be operated by driver like this, in other words, the aperture of throttle valve valve TV is detected, and will represent that the testing signal of the aperture detected is sent to ECU20.

Front brake action according to the operation amount of the above-mentioned front brake bar 15 based on driver, thus the rotation of front-wheel is stopped, the operation amount (that is, the actuating quantity of front brake) of front brake sensor 37 to this front brake bar 15 detects and the testing signal of the operation amount representing the front brake bar 15 detected is sent to ECU20.

Rear brake action according to the operation amount of the above-mentioned rear side brake rod 16 based on driver, thus the rotation of trailing wheel is stopped, rear brake sensor 38 to the operation amount of brake rod on rear side of this 16 (namely, the actuating quantity of rear brake) detect, and the testing signal of the operation amount representing the rear side brake rod 16 detected is sent to ECU20.

In engine controlling unit 100, ECU20 implements the idle stop control treatment of motor 30 and restarts process.Stop if idle stop control treatment is vehicle 10 and meets predetermined idling-stopping condition, then make the self-braking process of motor 30, be treated to if restart this idle stop control treatment perform after and meet the predetermined restart condition that throttle valve operation is done etc., then starter 33 driven and make the process that motor 30 is restarted.Specifically, idle stop control treatment is that the timing that have passed through predetermined standby time T1 (such as 3 seconds) stopping from vehicle 10 makes the self-braking process of motor 30.

In addition, be connected with as the time showing portion 22 through condition notification mechanism at ECU20.As mentioned above, time showing portion 22 stopping from vehicle 10 to during through standby time T1, showing through situation this standby time T1.As representing the example of this information through situation, in the first embodiment, time showing portion 22 such as from vehicle 10 stops to through standby time T1, namely to standby time T1 vanishing, display remaining time.

The predetermined timing t a (with reference to Fig. 5 and Fig. 6) that have passed through above-mentioned standby time T1 stopping from vehicle 10 makes in the structure of the self-braking above-mentioned idle stop control treatment of motor 30, to during through standby time T1 stopping from vehicle 10, even if driver considers and makes motor 30 stop rapidly, can not make engine stop from oil consumption aspect etc.In addition, when vehicle 10 is turned right and is waited for and stop in intersection, even if under originally not wanting the situation making motor 30 stop, in the structure of above-mentioned idle stop control treatment, if through standby time T1, motor 30 stops automatically, thus the oil consumption having the former to be related to vehicle 10 worsens, and the problem that the latter can bring uncomfortable worry such to driver.

In view of this point, engine controlling unit 100 in first mode of execution is to during through standby time T1 stopping from vehicle 10, and the operation based on driver decides the motion time table of the motor 30 of the timing of the process had precedence over based on above-mentioned standby time.

And, engine controlling unit 100 is formed as follows: even if stop according to this motion time table thirty years of age motor 30, that is, respond its operation and motor 30 is stopped, or, be the timing after predetermined timing t a by the constant time lag making motor 30 stop.

Fig. 3 is the flow chart representing the idle stop control treatment performed by ECU20.ECU20 performs this idle stop control treatment repeatedly with the predetermined cycle after the engine started.Below, according to this Fig. 3, involved idle stop control treatment is described.

As shown in Figure 3, first in step s 11, ECU20 to whether being in operating condition at motor 30, namely under the state of mixture combustion and vehicle 10 stopped judging.Whether the testing signal based on the speed of the expression vehicle 10 sent from vehicle speed sensor 35 stops judging to vehicle 10.When the result of determination of step S11 be motor 30 be in halted state, or for vehicle 10 be in traveling when (step S11 is no), ECU20 terminates idle stop control treatment.On the other hand, when motor 30 is in operating condition and vehicle 10 stopped (step S11 is yes), idle stop control treatment advances to step S12, and a series of process that ECU20 implementation step S12 is later.In addition, vehicle 10 by the front brake bar 15 of driver and rear side brake rod 16 such as to the operation of complete position, make front brake and rear brake action, thus stop, under this halted state, throttle valve handle 14 is positioned at initial position.That is, the operation amount of throttle valve handle 14 is zero.

In step s 12, ECU20 comes into effect the measurement of the transit time TX from vehicle 10 stops.Such as in the first embodiment, ECU20 is built-in with timer, and ECU20 uses this timer and carries out the measurement of transit time TX.Such as, ECU20 is in the timing being of step S11, and the timing that namely stopped at vehicle 10 makes timer carry out action, thus the reverse countdown from the initial value of zero of transit time TX is started.

In following step S13, ECU20 makes the difference of the value of transit time TX and timer, that is, be presented in time showing portion 22 to the remaining time through standby time T1.This standby time T1 be as described above, from vehicle 10 stops to the stand-by period making motor 30 automatically stop (idle stop), be such as set to 3 seconds.Thus, driver can know standby time T1 through situation.In addition, ECU20 is in the timing being of step S11, namely, the timing that vehicle 10 stopped, make timer action, thus the countdown of transit time TX is started, and the value of the timer of countdown will be carried out from transit time TX, that is, the remaining time to standby time T1 passes through is presented in time showing portion 22.

In following step S14, whether ECU20 reaches standby time T1 to the transit time TX measured by timer, namely judges whether have passed through standby time T1 from vehicle 10 stopping.When have passed through standby time T1 from vehicle 10 stopping (being yes in step S14), ECU20 performs the stopping process of motor 30 in step S22.Specifically, ECU20, by stopping the output to the output of the fuel injection command of sparger 31 and the firing command to ignition mechanism 32 respectively, stops based on the fuel injection of sparger 31 and the igniting based on ignition mechanism 32.Thus, motor 30 is stopped (with reference to Fig. 5) at timing t a.In step S18 thereafter, ECU20 terminates, by the measurement of the transit time TX of meter enforcement, then to terminate idle stop control treatment.

On the other hand, also without (being no in step S14) when standby time T1 when stopping from vehicle 10, ECU20 determines whether to have carried out based on driver the operation of throttle valve handle 14 in step S15 based on the testing signal of the aperture of the expression throttle valve valve TV sent from throttle valve opening sensor 36.

Specifically, in step S15, ECU20 is when basis is greater than predetermined threshold k 1 (with reference to Fig. 6) from the throttle valve opening W detected by this throttle valve opening sensor 36 calculated by the testing signal from throttle valve opening sensor 36 (W > K1), be judged to implement throttle valve operation (being yes in step S15), and idle stop control treatment can shift to step S19.On the other hand, at throttle valve opening W (W≤K1) threshold k less than 1, ECU20 can be judged to not implement throttle valve operation (being no in step S15), and idle stop control treatment advances to step S16.

In step s 16, ECU20 determines whether the operation having carried out being removed rear brake by the operation of the rear side brake rod 16 based on driver.Specifically, ECU20 is at the current operation amount H of the rear brake detected by rear brake sensor 38, in other words, when operation amount (operating position) based on the rear side brake rod 16 of driver is less than predetermined threshold k 2 (with reference to Fig. 5) (H < K2), be judged to be releasing operation (being yes in step S16) implementing rear brake.On the other hand, when the operation amount H of rear brake is threshold k more than 2 (H >=K2), ECU20 is judged to be releasing operation (being no in step S16) not implementing rear brake.

In the not effective situation of releasing operation being judged to be rear brake, idle stop control treatment is back to step S13.Its result, ECU20 from motor 30 stop to the process repeatedly performing step S13 ~ S16 through standby time T1.

On the other hand, when the releasing operation implementing rear brake, idle stop control treatment advances to step S17, and ECU20 performs the stopping process of motor 30 in step S17.This is treated to the process identical with the process of above-mentioned step S22.Namely, the motion time table of motor 30 not determines as representing the Schedule that the predetermined timing t a that have passed through time TX from above-mentioned vehicle 10 stops stopping by ECU20, even if but determined the motion time table for stopping according to releasing operation thirty years of age motor 30 of above-mentioned rear brake.

Thus, even if before standby time T1 passes through, also can respond the operation based on driver and motor 30 is stopped (stop the idling of the engine 30 (stopping the no load running of motor 30)) immediately.Then, in step S18, terminate the measurement of transit time TX at ECU20, and terminate present treatment afterwards.

On the other hand, in step S15, when being judged to implement the throttle valve operation based on driver (being yes in step S15), ECU20 is in step S19, based on the testing signal of the speed of the expression vehicle 10 sent from vehicle speed sensor 35, whether zero be continuously to the speed of vehicle 10 and judge.That is, in this step S19, although ECU20 operates the throttle valve implemented by driver, specifically, implement the operation of throttle valve handle 14, whether vehicle 10 still continues stopping judges.More specifically, usually when being implemented throttle valve by driver and operating, vehicle 10 starts to travel based on the operation of this throttle valve.On the other hand, can be considered as although implement the situation that throttle valve operation vehicle 10 still continues to stop, being implemented by driver and operate without travelling the special throttle valve of wish, that is, the situation of the operation of throttle valve handle 14.Therefore, in this step S19, ECU20 operates whether implementing relevant special throttle valve by driver, that is, the operation without the throttle valve handle 14 travelling wish judges.If the words further illustrated, then in the mode of execution of first, as relevant special throttle valve operation, be assumed to be, vehicle 10 does not also start the interim throttle valve operation (with reference to Fig. 6) of the only short time of the degree travelled, in this step S19, ECU20 implements relevant interim throttle valve to whether by driver and operates and judge.

In addition, after the process of this step S19 have passed through predetermined TU retard time (with reference to Fig. 6) being implemented from the process of step S15, in other words being implemented from the throttle valve operation based on driver, have passed through TU retard time after be implemented.At this, retard time, TU was set under the common throttle valve for making vehicle 10 travel operates effective situation, was greater than the time of time required to vehicle 10 starts to travel (in other words the speed of vehicle 10 is greater than zero) from the operation of this throttle valve is implemented.

In this step S19, when vehicle 10 does not stop i.e. when vehicle 10 starts to have travelled (being no in step S19), idle stop control treatment advances to step S18, and ECU20 terminates the measurement of transit time TX, and terminating idle stop control treatment afterwards.On the other hand, when vehicle 10 continues to stop (step S19 is yes), namely when being implemented interim throttle valve by driver and operating, idle stop control treatment advances to step S20.

In step S20, the motion time table of motor 30 not determines as representing the Schedule that the predetermined timing t a that have passed through transit time TX from above-mentioned vehicle 10 stops stopping by ECU20, but is determined the motion time table for making stopping constant time lag compared with predetermined timing t a.

Specifically, ECU20 performs engine stop delay disposal in step S20.This engine stop delay disposal is timing after above-mentioned predetermined timing t a by making the self-braking constant time lag of motor 30.In following step S21, ECU20 performs in this timing be delayed the engine stop process that motor 30 is stopped.This process is identical with the process of above-mentioned step S22.Then, in step S18, ECU20 terminates the measurement of transit time TX, and is terminating idle stop control treatment afterwards.

Next, based on Fig. 4, the engine stop delay disposal in step S20 is described.In addition, Fig. 4 is the flow chart representing engine stop delay disposal.

As shown in Figure 4, first in step S31, ECU20 sets the new standby time T2 the stopping to motor 30.At this, standby time T2 be from implemented by driver interim throttle valve operate (be judged to be in step S15 be) to the stand-by period making motor 30 automatically stop (idle stop).In the first embodiment, this standby time T2 is set to be greater than the time of above-mentioned standby time T1, such as, be set to 5 seconds.By the setting of this standby time T2, the timing that motor 30 is stopped is delayed by as the timing t b (with reference to Fig. 5 and Fig. 6) after predetermined timing t a.In addition, standby time T2 is equivalent to retard time.

In step s 32, ECU20 implements the reset based on the timing process of the transit time TX of timer, and the reverse countdown of the timer to transit time TX is restarted.Start the measurement of the transit time TX of from the interim throttle valve operation based on driver is implemented (being determined to be in step S15) thus.

Next in step S33, ECU20 by the difference of the value of transit time TX and timer, that is, to the remaining time showing through standby time T2 in time showing portion 22.Thus, driver can learn standby time T2 through situation.

In addition, in step s 32, ECU20 implements the reset based on the timing process of the transit time TX of timer, and the countdown from transit time TX is restarted, and, the value of timer of countdown will be implemented from transit time TX, that is, also can in time showing portion 22 to the remaining time showing through standby time T2.

In following step S34, whether ECU20 reaches standby time T2 to the transit time TX measured by timer judges, that is, judge whether have passed through standby time T2 being implemented from the interim throttle valve operation based on driver.When have passed through standby time T2 when being implemented from the operation of interim throttle valve (being yes in step S34), ECU20 terminates engine stop delay disposal, and be back to step S21 (Fig. 3) afterwards, and in this step S21, implement the stopping process of motor 30.Thus, the timing t b after predetermined timing t a makes motor 30 stop.

On the other hand, without (being no in step S34) when standby time T2 from the operation of interim throttle valve is implemented, engine stop delay disposal advances to step S35.

In step s 35, ECU20 is based on the testing signal of the aperture of the expression throttle valve valve TV sent from throttle valve opening sensor 36, and the operation again implementing throttle valve handle 14 by driver to whether judges.This process is identical with the process of above-mentioned step S15.When by driver, the throttle valve do not implemented again operates (being no in step s 35), engine stop delay disposal advances to step S36.

In step S36, the releasing that ECU20 implements rear brake to whether by driver operates and judges.This process is identical with the process of above-mentioned step S16.When being judged to be the releasing operation not implementing rear brake (being no in step S36), ECU20 is back to step S33, and to repeatedly performing the process of step S33 ~ S36 through standby time T2.

On the other hand, when being judged to be the releasing operation implementing rear brake (being yes in step S36), ECU20 terminates engine stop delay disposal, and is being back to step S21 (Fig. 3) afterwards, and in this step S21, implement the stopping process of motor 30.Thus, even if also responded the operation of driver and make motor 30 stop immediately before the process of standby time T2.

On the other hand, when again being implemented throttle valve by driver and operating (being yes in step s 35), engine stop delay disposal advances to step S37.In this step S37, whether ECU20, based on the testing signal of the speed of the expression vehicle 10 sent from vehicle speed sensor 35, is continuously zero to the speed of vehicle 10 and judges.Namely, in this step S37, although ECU20 is to again implementing throttle valve operation, whether vehicle 10 still continues stopping judges, and then in the same manner as above-mentioned step S19, ECU20 again implements interim throttle valve to whether by driver and operates and judge.

In addition, the process of this step S37 have passed through predetermined retard time and is implemented after TU being implemented from the process of step S35, in other words, is implemented after have passed through TU retard time again being implemented from the throttle valve operation based on driver.In addition, present treatment is essentially identical process with the process of above-mentioned step S19.

In this step S37, when vehicle 10 does not stop, namely when vehicle 10 starts to travel (being no in step S37), ECU20 is back to the step S18 of Fig. 3, and terminate the measurement of transit time TX, and terminating idle stop control treatment afterwards.

On the other hand, when vehicle 10 continues to stop (being yes in step S37), namely when again being implemented interim throttle valve by driver and operating, ECU20 is back to step S31, and again sets standby time T2 (being equivalent to retard time).Specifically, in step S31, the setting of the standby time T2 that ECU20 once sets before removing, and set new standby time T2.In this case, new standby time T2 is, from the interim throttle valve operation based on driver by (be judged to be in step S37 be) again implementing to the stand-by period making motor 30 automatically stop (idle stop).By the timing t c (reference Fig. 6) that the constant time lag making motor 30 stop is after timing t b by the setting again of this standby time T2.

Then, the ECU20 process that implementation step S32 is later again.Further, in the situation (situation being yes in step S34) that have passed through the standby time T2 again set, ECU20 terminates engine stop delay disposal, and implements the stopping process of motor 30 in step S21 (Fig. 3) afterwards.Thus, at the timing t c be delayed further compared with timing t b, motor 30 is stopped.On the other hand, when without the standby time T2 again set, ECU20 is to each process repeatedly performing step S33 ~ S36 through this standby time T2.

Further, although operate again implementing interim throttle valve by driver, in situation that vehicle 10 still continues to stop (step S35 is and the step S37 situation that is yes), ECU20 is again back to step S31 and again sets standby time T2.Like this, in this engine stop delay disposal, again implemented based on the interim throttle valve operation of driver before standby time T2, at every turn, then new standby time T2 is just set again and the stopping of motor 30 timing is delayed by.Therefore, it is possible to make the stopping timing infinite delay of motor 30 according to the wish of driver.

In addition, the ECU20 shown in Fig. 2 as determine to have precedence over the action of the motor 30 of the stopping timing t a of motor 30 the Schedule determination means of Schedule of being correlated with and playing a role.Particularly, the step S15 in ECU20, the process of S16, S17, S19, S20 and S21 as Schedule determination means a structure example and play a role.

Particularly, the step S15 in ECU20 and the process of S19 play a role to for making one of the decision mechanism of the different operation of the common operation of the throttle valve the traveling of vehicle 10 example as determining whether to be implemented this throttle valve by driver.

In addition, the process of the step S20 in ECU20, namely, the process of the step S31 shown in Fig. 4 ~ S37 and the process of step S21, as delay device one example and play a role, this delay device, by during till standby time T1, is set T2 retard time based on by the operation of driver to the such as throttle valve handle 14 as the first functional unit, and is made by this retard time of T2 the process of the stopping constant time lag of motor 30 implement as stopping process.

Step S16 in ECU20 and the process of S17 as shut-down mechanism an example and play a role, this shut-down mechanism is by during till standby time T1, and the operation responded as the such as rear side brake rod 16 of the second functional unit processes as stopping using the process making motor 30 and stops and implementing.

Particularly, the process of the step S16 in ECU20 plays a role as to whether operating an example of the second decision mechanism that described second functional unit judges by driver.

Next, based on Fig. 5 and Fig. 6, the concrete action of the engine control system 10 performed when comprising the idle stop control treatment of above-mentioned engine stop delay disposal is described.Fig. 5 represents the sequential chart in the concrete action responding the engine controlling unit 100 when making motor 30 stop immediately based on the releasing operation of the rear brake of driver.Fig. 6 be represent when operating based on the interim throttle valve by driver by motor 30 is stopped constant time lag the sequential chart of concrete action of engine controlling unit 100.

First, based on Fig. 5, the concrete action of the engine controlling unit 100 when motor 30 being stopped immediately in the releasing operation responded based on the rear brake of driver is described.

In Figure 5, symbol (a) represents the change of the speed (speed of a motor vehicle) of vehicle 10, symbol (b) represents the change of the aperture (throttle valve opening) of throttle valve valve TV, and in addition, symbol (c) represents the operating state of timer.In addition, in Figure 5, symbol (d) represents the operating state of motor 30, and symbol (e) represents the operating state of rear brake, and in addition, symbol (f) represents the operating state of front brake.

As shown in Figure 5, before timing t 11, motor 30 is in operating condition, and vehicle 10 is in traveling.Now, by driver, throttle valve handle 14 operated and make it be in precalculated position.

At this, if make the releasing of throttle valve handle 14 operate in timing t 11 by driver, namely, the releasing operation of throttle valve starts and operates front brake bar 15 and rear side brake rod 16 by driver thus making the operation to the working state of the front brake of correspondence and rear brake, then the speed of vehicle 10 starts along with the process of time to reduce.Afterwards, vehicle 10 stops in timing t 12.In addition, now, motor 30 is still in operating condition.

Now, the judgement of the step S31 of idle stop control treatment becomes and is, and starts the measurement (with reference to step S12) of the transit time TX based on timer in timing t 12.At this, be located at transit time TX arrive timing t 13 before standby time T1, namely from vehicle 10 stops to the timing t 13 before standby time T1, the releasing started based on the rear brake of driver operates.Its result, if when the operation amount of brake rod 16 is lower than threshold k 2 on rear side of timing t 14 afterwards, is then judged to be releasing operation (result of determination of step S16 is yes) implementing rear brake.Therefore, motor 30 is stopped (with reference to timing t 14, step S17).Thus, even if to during through standby time T1 stopping from vehicle 10, also can respond the releasing operation based on the rear brake of driver and motor 30 is stopped immediately.

In addition, as shown in the symbol (f) of Fig. 5, for front brake, after timing t 13, also maintain this working state.Therefore, although timing t 13 implement rear brake releasing operation, rear vehicle 10 also can be maintained at the halted state stabilized.In addition, owing to performing engine stop process in timing t 14, therefore the measurement of transit time TX also terminates (with reference to step S18).

Next, the concrete action of the engine controlling unit 100 when to make the stopping constant time lag of motor 30 to operating based on the interim throttle valve by driver based on Fig. 6 is described.

In figure 6, the parameter shown in symbol (a) ~ (f) that the parameter represented by symbol (a) ~ (f) and Fig. 5 represent is identical.

As shown in Figure 6, to the vehicle 10 in travelling stops, the effect of (timing t 21 ~ t22) is identical with Fig. 5, and starts the measurement (with reference to step S22) of the transit time TX based on timer in timing t 22.

Afterwards, be located at the timing t 23 before transit time TX arrival standby time T1, namely starting to operate based on the interim throttle valve of driver to the timing t 23 before standby time T1 stopping from vehicle 10.Its result, reaches threshold k 1 in the aperture of timing t 24 throttle valve valve afterwards, is judged to implement throttle valve operation (result of the judgement of step S15 is yes).Then, whether the timing t 25 after have passed through TU retard time from this timing t 24, continue stopping to vehicle 10 and judge (step S19).Throttle valve due to present driver is operating as interim throttle valve operation, therefore vehicle 10 continues to stop (result of the judgement of step S19 is yes), thus new standby time T2 is set (with reference to step S31), and the timing process based on the transit time TX of timer is resetted, from this standby time T2, again starts countdown (with reference to timing t 25, step S32).

Made the stopping of motor 30 timing be delayed to the timing t b after standby time T2 measures from timing t 25 by the setting of this standby time T2.

Afterwards, the timing t 26 before standby time T2 is arrived at transit time TX, namely be implemented (from timing t 25) in the interim throttle valve operation based on driver, in the timing t 26 before standby time T2, started the interim throttle valve operation again based on driver.Then, reach threshold k 1 in the aperture of timing t 27 throttle valve valve afterwards, be judged to implement throttle valve operation (result of the judgement of step S35 is yes).Then, the timing t 28 after have passed through TU retard time from this timing t 27 judges whether vehicle 10 continues to stop (with reference to step S37).Throttle valve operation due to this driver is also interim throttle valve operation, therefore vehicle 10 still continues to stop (result of the judgement of step S37 is yes), thus again set new standby time T2 (with reference to step S31) and the timing process based on the transit time TX of timer is resetted, from the standby time T2 that this sets again, again start countdown (with reference to timing t 28, step S32).Its result, the stopping timing of motor 30 is by the timing t c be delayed to further from timing t 28 after standby time T2 amount.

Afterwards, the delay timing tc (t29) after have passed through standby time T2 makes motor 30 automatically stop (result of step S34 is yes, and with reference to step S21).In addition, terminate (with reference to step S18) in the measurement of this timing t 29 transit time TX.

The structure of the engine controlling unit 100 in above the first described in detail mode of execution can obtain following excellent effect.

Engine controlling unit 100 stopping from vehicle 10 to during through standby time T1, based on situation about being implemented by driver from operate for making the common throttle valve the traveling of vehicle 10 operate different special throttle valve, not is determined the motion time table that the predetermined timing t a for being specified by above-mentioned standby time T1 stops the actuation time of motor 30, but determined the motion time table into the timing t b after this predetermined timing t a stops, that is, to timing t b, make the motion time table that the action of motor 30 continues.

Specifically, engine controlling unit 100 is to be formed the mode of the timing t b after the constant time lag making motor 30 stop to the predetermined timing t a specified by above-mentioned standby time T1.Thereby, it is possible to make the stopping of motor 30 postpone in the wish according to driver before standby time T1.Therefore, such as, when vehicle 10 right-hand rotation is waited for and stopped in intersection, the self-braking situation of motor 30 can be avoided, thus the uncomfortable feeling of the driver automatically being stopped the vehicle 10 caused by this can be eliminated.

What is called makes the stopping of motor 30 postpone, that is, make the idle state of motor 30 extend, namely continue corresponding amount.From this point, the throttle valve of the operation as the wish expressing the driver making operating condition extend is utilized to operate the above-mentioned structure that the stopping of motor 30 is postponed, implementing the delay operating aspect of the stopping of motor 30 driver, is the structure for driver's easy understand.

The said structure of engine controlling unit 100 makes the stopping of motor 30 postpone based on by driver to the operation being originally arranged at the throttle valve handle 14 of vehicle 10.Therefore, without the need to arranging the new functional unit for implementing delay operation in vehicle 10 in addition, the complex structure of vehicle 10 can be avoided thus and obtaining above-mentioned each effect.

In addition, engine controlling unit 100 is when being judged to implement the throttle valve operation based on driver, although when implementing the operation of this throttle valve but the speed of the vehicle 10 detected by vehicle speed sensor 35 is still continuously zero, being judged to be that this throttle valve is operating as and operating different special throttle valve from common throttle valve and operate (interim throttle valve operates).According to this structure, can judge aptly to implement and to operate the situation that different special throttle valve operates, the throttle valve of the wish of delay that namely stops based on the motor 30 of driver operates from the common throttle valve for making the traveling of vehicle 10 start.

And, engine controlling unit 100 stopping from vehicle 10 to during through standby time T1, to operate the situation that different special throttle valve operates from common throttle valve set standby time T2 (retard time) based on being implemented by driver, and when again being implemented to the throttle valve operation based on driver during through this standby time T2, again set new standby time T2.According to this structure, operating to again implementing throttle valve by driver during through standby time T2 at every turn, then the stopping timing of motor 30 is just delayed by.Therefore, it is possible to ad infinitum give the chance of the stopping delay that driver makes motor 30, thus can realize further controlling according to the idle stop of the wish of driver.

Engine controlling unit 100 stopping from vehicle 10 to during through standby time T1, respond and implement by driver the situation operating different special throttle valve from common throttle valve and operate, the timing of standby time T1 is resetted, and sets the standby time T2 (retard time) longer than this standby time T1.Due to according to this structure, the stopping constant time lag of motor 30 can be made to timing more rearward, therefore vehicle 10 to wait for turn right and the situation in intersection of stopping at inferior, originally do not want the situation that motor 30 is stopped under, the situation that can reliably avoid motor 30 to stop further.

Engine controlling unit 100 from vehicle stop before standby time T1, when there occurs the releasing operation based on the rear brake of driver, the motion time table of motor 30 is not determined the Schedule for stopping at above-mentioned predetermined timing t a, even if but determine the motion time table that releasing operation thirty years of age motor 30 for corresponding to above-mentioned rear brake stops.

Specifically, engine controlling unit 100 responds the releasing operation based on the rear brake of driver and motor 30 is stopped immediately.According to this structure, when driver makes motor 30 promptly stop in oil consumption etc., through standby time T1, motor 30 can be stopped without the need to waiting for.In addition, to during through standby time T1, driver can be avoided in the situation waited in uneasiness because of not knowing motor when to stop.

Engine controlling unit 100 implements the releasing of rear brake under the state of operating state maintaining front brake.According to this structure, in the cart 10 that vehicle body compared with four-wheel car is more unstable, the halted state stabilized can be maintain and also performs the stopping having responded the motor 30 removing operation.

Because rear side brake rod 16 is arranged at the opposition side of throttle valve handle 14 in the body forward structure 11 faced toward with driver, therefore driver can leave throttle valve handle 14 and easily implement the operation that rear brake removes.Therefore, it is possible to compared with the operating characteristics of high maintenance driver.

Engine controlling unit 100 possess from vehicle 10 stop till standby time T1 during, to the time showing portion 22 shown through situation of this standby time T1.According to this structure, driver can hold this through situation during through standby time T1.Therefore, it is possible to avoid driver occurring because not knowing when motor stops and the situation of uneasiness.In addition, in said structure, driver can with reference to the situation of surrounding during running and standby time T1 through situation, thus carry out the stopping constant time lag making motor 30 or the judgement shifted to an earlier date.Therefore, driver can make motor 30 stop on optimal opportunity further.

(the second mode of execution)

With reference to Fig. 7 ~ Fig. 9, the engine control system involved by the second mode of execution of the present invention is described.

Engine controlling unit 100 involved by above-mentioned first mode of execution is with based on by the operation of driver to functional unit, thus makes motor 30 carry out the structure controlled in the mode that the timing different from predetermined timing stops.On the other hand, engine controlling unit 100A involved by second mode of execution is for replacing said structure or add other structures in said structure, with the operation based on the functional unit by driver, forbid that the self-braking mode of motor 30 carries out the structure controlled.Below, the structure of the engine controlling unit 100A involved by the second mode of execution is described.

In addition, in this second embodiment, for the structure of vehicle 10, and the structure of engine controlling unit 100A, except following main points, with the structure of the vehicle 10 in above-mentioned first mode of execution and the structure of engine controlling unit 100 substantially identical.Therefore, to the structural element identical with the structural element of vehicle 10 and engine controlling unit 100 in the structure of engine controlling unit 100A, also the description thereof will be omitted for additional same-sign, further, the structure emphasis different from the structure of the vehicle 10 in the first mode of execution and the structure of engine controlling unit 100 is described.

As shown in Figure 2, the engine controlling unit 100A involved by the second mode of execution possesses the diverter switch 25, cancel switch 26 and the idle stop display unit 28 that are connected in the mode that can communicate with ECU20.In addition, in fig. 2, except the structural element of the engine controlling unit 100 of the first mode of execution, also added the structure of the engine controlling unit 100A of structure involved by the second mode of execution of diverter switch 25, cancel switch 26 and idle stop display unit 28.

Diverter switch 25 is for by the device making the requirement of the effective and invalid some switchings of the idle stop function of engine controlling unit 100A be sent to ECU20.

Cancel switch 26 is for will the idle stop function in engine controlling unit 100A be made to stop the requirement of (cancellation) to be sent to the device of ECU20 temporarily.

Diverter switch 25 is arranged near right side handlebar in the body forward structure 11 of such as vehicle 10 and wing mirror, and cancel switch 26 is such as arranged near right side handlebar 12 in the body forward structure 11 of vehicle 10 and stop switch 24 (with reference to Fig. 1).

ECU20 is in the traveling of vehicle 10, based on the operation information of the diverter switch 25 by driver or the operation information of cancel switch 26, the automatic stopping of the motor 30 when the vehicle 10 determining whether to forbid under steam stops next time, and decide according to result of determination the automatic stopping performing or forbid motor 30.

Specifically, this pattern can switch to by ECU20, and the idle stop function in engine controlling unit 100A is effective effective model or idle stop function is invalid invalid mode.

That is, this pattern can switch according to the operation information of the operation information of diverter switch 25 or cancel switch 26 by ECU20 between effective model and invalid mode.

Specifically, if such as operate diverter switch 25 by driver to be ON (unlatching), then ECU20 shifts to effective model, on the other hand, if such as operate diverter switch 25 by driver to be OFF (closedown), then ECU20 shifts to invalid mode (off mode).Further, ECU20 is to perform idle stop control treatment vehicle 10 stopped in the action of effective model, and the mode not performing idle stop control treatment when making vehicle 10 stopped in the action of invalid mode is formed.

Similarly, ECU20 at cancel switch 26 not by under the state that operates, carry out action with effective model, if such as operate cancel switch 26 by driver in the traveling of vehicle 10, then this pattern is set to off mode (invalid mode).Further, ECU20 makes vehicle 10 stopped in this off mode, when this stopping not making the self-braking mode of motor 30 control, that is, the control forbidding the execution of idle stop control treatment is implemented.

In addition, at this, in this second embodiment, diverter switch 25 and/or cancel switch 26 are equivalent to the 3rd functional unit.

ECU20 is connected to the idle stop display unit 28 of status of implementation for showing idle stop etc.Idle stop display unit 28 such as has the luminous displaing part of LED etc., and this luminous displaing part can be made to throw light on or flicker.This idle stop display unit 28 is arranged in body forward structure 11, such as display unit 21 neighbouring (with reference to Fig. 1).

Such as ECU20, under the automatic stop condition and idle stop state of motor 30, controls idle stop display unit 28 and this luminous displaing part is glimmered.In addition, ECU20, under off mode state, controls idle stop display unit 28 and this luminous displaing part is turned off the light, under the relieving state (in other words the holding state of idle stop) of off mode, idle stop display unit 28 being thrown light on.

Next, with reference to Fig. 7, the off mode setting process performed by ECU20 is described.

ECU20 judges after the engine started, whether operate cancel switch 26 by driver and sent its operation signal (step S30).In addition, the pattern of ECU20 in an initial condition, is effective model, and idle stop display unit 28 is illumination.

If sent the words (result of the judgement of step S30 is yes) of operation signal from cancel switch 26 by the operation of driver, then whether ECU20 has been in deceleration regime to vehicle 10 and has judged (step S31).

When vehicle 10 is in deceleration regime (result of the judgement of step S31 is yes), this pattern (original state is effective model) is transferred to off mode (invalid mode) (step S32) by ECU20.Next, ECU20 implements to turn off the light to idle stop display unit 28 and controls (step S33).

After the process of step S33, whether ECU20 judges (step S34) in predetermined threshold k more than 3 aperture of throttle valve valve TV based on the testing signal sent from throttle valve opening sensor 36.If the aperture that the result of this process is judged as throttle valve valve TV does not reach predetermined threshold k 3 (result of determination of step S34 is no), then ECU30 performs the process of step S34 repeatedly.

Further, if be judged to be, the aperture of throttle valve valve TV is in predetermined threshold k more than 3 (result of determination of step S34 is yes), then this pattern shifts to effective model by ECU20, and makes idle stop display unit throw light on (step S35).Afterwards, ECU20 terminates off mode setting process.

On the other hand, when not sending operation signal from cancel switch 26 (result of determination of step S30 is no), or vehicle 10 is not when being in deceleration regime (result of determination of step S31 is no), ECU20 terminates off mode setting process.

Like this, the pattern of ECU20 can be switched to the off mode (invalid mode) removing idle stop control treatment by the operation of cancel switch 36.

In addition, in this second embodiment, in vehicle deceleration, the pattern of ECU20 can be changed to the chance of off mode by restriction from effective model.

Next, the flow chart according to Fig. 8 and the sequential chart shown in Fig. 9 are described particularly to the idle stop control treatment comprising the idle stop canceling process performed by ECU20.

Fig. 8 is the flow chart representing the idle stop control treatment performed by ECU20.ECU20 performs this idle stop control treatment repeatedly with the predetermined cycle after the engine started.Below, based on this Fig. 8, relevant idle stop control treatment is described.In addition, in the idle stop control treatment shown in Fig. 8, also the description thereof will be omitted for the step number additional identical to the process (step) identical with Fig. 3.

Be yes in the process of step S11, that is, motor 30 be in operating condition and vehicle 10 stopped when (being yes in step S11), ECU20 judges this pattern whether as effective model (step S11a).In other words, ECU20 judges that this pattern is effective model or off mode (invalid mode) (step S11a).

When the pattern of ECU20 is effective model (result of determination of step S11a is yes), ECU20 performs the process after step S12 illustrated in fig. 3.

On the other hand, when the pattern of ECU20 is off mode (result of determination of step S11a is no), ECU20 does not perform the process after step S12 illustrated in fig. 3, but terminates idle stop control treatment.

Next, be described performing concrete action when comprising the idle stop control treatment of above-mentioned idle stop canceling process, engine control system 10 based on Fig. 9.

In fig .9, symbol (a) represents the change of the pattern of ECU20, symbol (b) represents the change of the speed (speed of a motor vehicle) of vehicle 10, and in addition, symbol (c) represents the change of the aperture (throttle valve opening) of throttle valve valve TV.In addition, in fig .9, symbol (d) represents the operating state of motor 30, and symbol (e) represents the operating state of one of them side of rear brake and front brake.

As shown in Figure 9, before timing t 31, under vehicle 10 stops at idle stop state (i.e. the halted state of motor 30).Now, throttle valve handle 14 is positioned at initial position.In addition, front brake bar 15 or rear side brake rod 16 lay respectively at complete position, its result, by the action of one of them side (following, only to set it as action break) of front brake and rear brake, vehicle 10 are stopped.

At this, if in the operation of timing t 31 throttle valve handle 14 by driver, that is, throttle valve operation, and operate by the releasing of the brake rod corresponding with action break and action break is removed, then vehicle 10 starts traveling.

If the timing t 32 in vehicle travels, when the throttle valve operation based on driver is removed, then vehicle 10 reduces speed now.And, if the timing t 33 under the deceleration regime (in deceleration) of vehicle 10 is implemented to operate based on the ON of the cancel switch 26 of driver, then the pattern of ECU20 becomes off mode (step S30, S31 and S32 with reference to Fig. 7).

That is, in this second embodiment, be set as based on the handover operation to off mode of cancel switch 26 and be only limitted to during vehicle 10 is in deceleration regime in Tm effectively.That is, the handover operation to the off mode of ECU20 is defined in period Tm for effectively removing the valid period.Therefore, even if implement the ON operation of cancel switch 26 beyond this releasing valid period Tm, this ON operation is also invalid, and the pattern of ECU20 also can not become off mode (being judged as no in step S31).

More specifically, ECU20, when the speed of the vehicle 10 detected by vehicle speed sensor 35 reduces along with the process of time, is judged to be that vehicle 10 is in deceleration regime.Further, this vehicle 10 is judged to be for Tm during deceleration regime for removing the valid period.In addition, remove the valid period might not be defined in vehicle deceleration during Tm, such as also can by vehicle travel in whole period (the symbol Tn in Fig. 9) be set to remove the valid period.

Vehicle 10 stops in timing t 34 afterwards.When this vehicle 10 stops, pattern due to ECU20 is off mode, even if therefore become the timing t a that to have passed through from timing t 34 after standby period T1, motor 30 also can not be made automatically to stop (result of determination of the step S11a in Fig. 8 is no).Therefore, vehicle 10 continues to stop under the operating condition of motor 30.

In timing t 35 afterwards, the operation of throttle valve handle 14 by driver, that is, throttle valve operation, and operate by the releasing that driver starts the brake rod corresponding with action break, that is, the releasing of action break operates.Thus, vehicle 10 starts to travel.

Further, if reach predetermined threshold k 3 in the aperture of timing t 36 throttle valve valve TV afterwards, then off mode is removed, thus the pattern of ECU20 is back to effective model (with reference to step S34 and S35).Specifically, as mentioned above, ECU20, when the aperture of the throttle valve valve detected by throttle valve opening sensor 36 becomes threshold k more than 3, is judged to be that vehicle 10 has started to travel, and off mode is removed.By this process, when next vehicle stops, performing the automatic stopping (result of determination of step S11a is yes) of motor 30.

Above, the structure of the engine controlling unit 100A of the second mode of execution of detailed description can obtain following excellent effect.

Engine controlling unit 100A, with the operation of the cancel switch 26 of the driver in the traveling based on vehicle 10, forbids that the self-braking mode of the motor 30 when the next time of vehicle 10 stops is formed.Thus, under the situation (traffic condition) not wanting to make motor 30 stop, motor 30 can be preset as lasting operating condition.That is, owing to can forbid the automatic stopping of motor 30 based on the wish of driver, thus can eliminate and automatically stop the uncomfortable feeling of the driver caused by this.

Specifically, engine controlling unit 100A, with the operation of the cancel switch 26 of the deceleration regime based on vehicle 10, forbids that the self-braking mode of motor 30 is formed.The situation that so-called vehicle 10 is in deceleration regime refers to, is about to make the state before vehicle 10 stopping.Therefore, in this case, the situation (traffic condition etc.) before vehicle 10 stopping can be made according to being about to, forbidding the automatic stopping of motor 30.

Engine controlling unit 100A, to have started situation about travelling based on vehicle 10, removes the off mode of ECU20, that is, remove and forbid that the mode of the self-braking prohibited mode of motor 30 is formed.Thus, wait in the U-shaped turning in intersection or in the situations such as wait of turning right, as long as under driver does not want to make the self-braking situation of motor 30, just can forbid the idle stop of motor 30.In addition, if because vehicle 10 starts to travel, off mode will automatically be removed, therefore with remove compared with the situation of the off mode of ECU20 with the operation etc. of driver to cancel switch 26 itself or other switch, owing to not needing the operation behavior of the switching manipulation of driver etc. when the off mode of each releasing ECU20, therefore, it is possible to improve the convenience of driver.

In addition, although in this second embodiment, make the pattern of ECU20 be transferred to off mode by the operation of the cancel switch 26 based on driver, but the present invention is not limited to this structure.

Such as, in this second embodiment, also the pattern of ECU20 can be made to transfer to off mode by the operation of the diverter switch 25 based on driver.

That is, in step s 30, ECU20 judges after the engine started, whether implements OFF by driver to diverter switch 25 and operates, and sent its operation signal (step S30).In addition, the pattern of ECU20 is effective model in an initial condition, and idle stop display unit 28 throws light on.

If sent from diverter switch 25 by the operation of driver and represented the operation signal (judgement of step S30 is become) that this OFF operates, then ECU20 performs the process of below step S32, this pattern, under deceleration regime, is transferred to off mode (with reference to step S32) by vehicle 10.

But, in this variation, step of replacing S34, ECU20 determines whether to have been sent from diverter switch 25 by the operation of driver to represent the operation signal (step S34a) that this ON operates, if sent above-mentioned ON operation signal (result of determination of step S34a is yes) from diverter switch 25, then its pattern has been transferred to effective model and idle stop display unit is thrown light on (with reference to step S35) by ECU20.

Like this, in this variation, by the operation of diverter switch 25, the pattern of ECU20 can be switched to, the effective model effectively performing idle stop control treatment and the one party removed in the off mode (invalid mode) of idle stop control treatment.Its result, can obtain with the roughly the same effect of the effect acquired by the second above-mentioned mode of execution (but, not based on the effect of process off mode being automatically switched to effective model).

(other mode of execution)

The present invention also can be not limited to above-mentioned mode of execution and such as implement as follows.

As the first variation, in the above-described first embodiment, ECU20 also can based on stop from vehicle 10 to the interim throttle valve operation based on driver during through standby time T1, forbid the automatic stopping (idle stop) of motor 30.If formed like this, then can wait for turn right at vehicle 10 and stop at the situation of intersection inferior, do not want to make the self-braking situation of motor 30 under, reliably avoid the self-braking situation of motor 30.Such as, in the idle stop control treatment shown in Fig. 3, when being judged to implement the interim throttle valve operation based on driver in step S15 (result of determination of step S15 is yes), ECU20 performs ending process of the measurement of the transit time TX in step S18, afterwards, idle stop control treatment (arrow with reference to the imaginary line in Fig. 3) can be terminated.That is, by being set to the idle stop control treatment of each process deleting step S19 ~ S21 in figure 3, above-mentioned first variation can be specialized.

In the above-described first embodiment, ECU20 is to during through standby time T2, again standby time T2 is set based on again being implemented the situation that interim throttle valve operates by driver, thus infinitely to give the chance that driver can set standby time T2, even if the mode of the chance of the stopping constant time lag of motor 30 is formed, but the present invention is not limited to this structure.

Such as, as the second variation, ECU20 also can limit the chance that driver can set standby time T2.Such as the upper limit of the number of times again setting standby time T2 can be set to three inferior, thus restriction can be applied to the set point number of standby time T2.The restriction of the set point number of this standby time T2, such as can by being limited in the algorithm of the engine stop delay disposal shown in Fig. 4, judged by the affirmative judgement of step S35 and the affirmative of step S37 and be back to the number of times of the later process of step S31, specialize.In addition, ECU20 also can limit the setting application time of standby time T2.Such as, can make ECU20 only can stopping from vehicle 10 such as, to setting standby time T2 in during till predetermined time (being the time longer than standby time T1,15 seconds).Corresponding to the time restriction of the setting of this standby time T2, can pass through with such as in the algorithm of the engine stop delay disposal shown in Fig. 4, in step s 35, again implement throttle valve operation timing exceeded from vehicle 10 stop above-mentioned predetermined time when, the mode again set not performing standby time T2 is formed to be specialized.

In addition, also the algorithm of the engine stop delay disposal shown in Fig. 4 can be changed to the setting again not performing standby time T2.Such as, in the algorithm of the engine stop delay disposal shown in Fig. 4, can change to when the judgement of step S34 is no, the process to step S36 is shifted.In this case, the chance of standby time T2 can be set for driver, even if the chance of the stopping constant time lag of motor 30 is restricted to once.

Although in the above-described first embodiment, standby time T2 (retard time) is set as the time longer than standby time T1, but as the 3rd variation, also standby time T2 can be set as the time identical with standby time T1, standby time T2 can also be set as the time shorter than standby time T1.

In addition, in the above-described first embodiment, although by based on (following based on the standby time T2 set by the interim throttle valve operation of driver in during till standby time T1, this standby time T2 is called standby time T2a), with based in during till standby time T2a based on the interim throttle valve of driver again to operate set standby time T2 (following, this standby time T2 is called standby time T2b) be set as same time, but also standby time T2a and standby time T2b can be set as the different time.Such as, standby time T2b can be set as the time longer than standby time T2a.

In addition, when again setting standby time T2 (T2a), also the standby time T2 again set can be set as the time of standby time T2 length when setting than the last time.

As the 4th variation, engine controlling unit 100 in the respective embodiments described above and 100A possess the operation based on functional unit respectively and change the standby time changing unit of the length of the standby time T1 preset, ECU20 also can have passed through the timing of the standby time T1X changed by this standby time changing unit stopping from vehicle 10, and motor 30 is stopped.Such as, in step S14 in the algorithm of the idle stop control treatment shown in Fig. 3, ECU20 whether can arrive the transit time TX measured by timer the standby time T1 replacing presetting, standby time T1X after above-mentioned change judges, namely judge whether have passed through standby time T1X stopping from vehicle 10.

In the 4th variation, timing that can be different at the predetermined timing t a that have passed through the standby time T1 preset from the stopping from vehicle 10, makes motor 30 stop.In addition, by the structure of the length of the modifiable standby time of the structure as the 4th variation can be by the automatic stopping timing setting of motor 30 timing of the wish meeting driver.

In addition, as the functional unit in the 4th variation, such as, in FIG with shown in imaginary line, body forward structure 11 be for example there are to the operation inputting part ID of the variable dial being set to be operated by driver etc.That is, driver can send arbitrary transit time TX by this operation inputting part ID of operation to the ECU20 be connected with this operation inputting part ID.In addition, the operation of the functional unit based on driver in the 4th variation, implements also can in either party in the stopping of vehicle 10 and in the traveling of vehicle 10.That is, the operation of the functional unit based on driver in the 4th variation, also can be not limited to and implement in during through standby time T1 the stopping from vehicle 10.

Although in the above-described first embodiment, ECU20 is with when to when implementing the releasing operation of rear brake in during through standby time T1 or T2, respond this releasing operation and mode that motor 30 is stopped is formed, but the present invention is not limited to this structure.

Namely, as the 5th variation, the timing advance that motor 30 is stopped also can be in the timing (with reference to step S16 and S17) before the timing t a of standby time T1 the stopping from vehicle 10 by ECU20, or by it in advance in the timing before the timing t b of standby time T2 (with reference to step S36 and S21) from the operation of interim throttle valve, instead of be the timing that the releasing of corresponding rear brake operates in advance by it.In the 5th variation, when driver makes motor 30 stop rapidly from the viewpoint of oil consumption etc., the process of standby time T1 can be waited for and motor 30 is stopped.

Although in the above-described first embodiment, although ECU20 operates to implement throttle valve by driver, when the speed of a motor vehicle is continuously zero, be judged to be that the mode that this throttle valve is operating as the operation of interim throttle valve is formed, the present invention is not limited to this structure.As the 6th variation, such as, ECU20 is as step S19a, also the operating time TW (with reference to Fig. 6) implementing throttle valve operation can be calculated based on the testing signal from throttle valve opening sensor 36, and when this calculate time TW be the scheduled time (as 0.5 second) below, be judged to be that this throttle valve is operating as the operation of interim throttle valve.In the 5th variation, also suitably can judge to implement and operate different throttle valve from the common throttle valve for making the traveling of vehicle 10 start and operate, the situation of the throttle valve operation of the delay wish namely stopped based on the motor 30 of driver.

In the above-described first embodiment, ECU20, with when being implemented interim throttle valve by driver and operating, is judged to implement and operates the mode that different special throttle valve operates from common throttle valve and form.Specifically, as the 7th variation, ECU20 is in the process of step S15 and S19, though when being implemented throttle valve by driver and operate but the speed of vehicle 10 being still continuously zero, be judged to implement the operation of above-mentioned special throttle valve, but in the present invention, judge that the decision method implementing special throttle valve operation need not be defined in this structure.

Such as, ECU20 also can be judged to be based on the testing signal from throttle valve opening sensor 36, be judged to be that the throttle valve implementing more than pre-determined number by driver in the given time operates, when the operation (throttle valve open operation) of in other words opening throttle valve valve TV and operation (the throttle valve closing operation) of closing this throttle valve valve TV, be judged to implement special throttle valve operation (with reference to Figure 10, step S19b).

Usually, when implementing the operation of the throttle valve in order to make the traveling of vehicle 10 start, multistage throttle valve operation can not be implemented at short notice.Therefore, the situation of the special throttle valve operation of the delay wish implemented based on driver suitably can be judged in the 7th variation.

In addition, in the 7th variation, based on the testing signal from throttle valve opening sensor 36, ECU20 also can when being judged to be that throttle valve operation amount is below prearranging quatity, namely, when the throttle valve opening W being judged to operate is below predetermined aperture, be judged to implement special throttle valve operation (with reference to Figure 10, step S19c).

When implementing the operation of the throttle valve in order to make the traveling of vehicle 10 start, throttle valve operation is implemented by with operation amount larger in a way.Therefore, also can suitably judge in this case to implement special throttle valve operation.

Further, in the 7th variation, ECU20 also can in increase and the minimizing that determined the throttle valve operation amount repeatedly performing more than pre-determined number in the given time based on the testing signal from throttle valve opening sensor 36, namely, when repeatedly performing increase and the minimizing of the throttle valve opening W of more than pre-determined number in the given time, be judged to implement special throttle valve operation (with reference to Figure 10, step S19d).

Implement in order to the traveling of vehicle 10 is started throttle valve operation time, usually can not repeatedly throttle valve operation amount increase change and reduce change.Therefore, in this case, the situation of the special throttle valve operation of the delay wish implemented based on driver can also suitably be judged.

Further, in the 7th variation, by the process process of the process of step S19b and S19c merged, ECU20 also based on the testing signal from throttle valve opening sensor 36, can determine whether that implementing special throttle valve operates.Namely, ECU20 also can when throttle valve operation amount be in the scope of below prearranging quatity, when the increase and the minimizing that are judged to be the throttle valve operation amount repeatedly performing more than pre-determined number in the given time, be judged to implement special throttle valve operation.

In the above-described first embodiment, ECU20 in step S15 and S19 based on the special operation of throttle valve handle 14, namely, make the automatic stopping constant time lag of motor 30 without the interim operation travelling wish, but the present invention is not limited to this structure.Such as, as the 8th variation, ECU20 also can based on the clutch of front brake bar 15, rear side brake rod 16, not shown vehicle 10, handlebar 12,13 etc. other functional unit (the first functional unit) make the automatic stopping constant time lag of motor 30 without the interim operation travelling wish.That is, if arbitrary functional unit is as the functional unit operated by the stopping constant time lag in order to make motor 30.

In the above-described first embodiment, ECU20 responds the releasing operation of rear brake, in other words, and the closing operation of rear brake and make motor 30 stop (with reference to step S16), but the present invention is not limited to this structure.Such as, as the 9th variation, ECU20 also can in step s 16, the releasing operation of response front brake, or the releasing of the dual brake of response front brake and rear brake operates and motor 30 is stopped.

In addition, as the 9th variation, ECU20 also can respond in step s 16 from the off working state of rear brake or front brake to the operation of working state, that is, respond the open operation of rear brake or front brake and motor 30 is stopped.In addition, ECU20 also can in step s 16, response implement in the given time the rear brake of more than pre-determined number or front brake open operation (in other words as, open and close operates) situation and motor 30 is stopped.

Further, in the 9th variation, ECU20 also can respond in step S make to be arranged at vehicle 10 clutch, throttle valve handle 14, starter 33 open and close switch (activator switch) etc., the operation of functional unit (the second functional unit) beyond break and motor 30 is stopped.That is, if arbitrary functional unit is as in order to make motor 30 stop operated functional unit immediately.

As the tenth variation, ECU20 also can based on be arranged at vehicle 10 activator switch (being equivalent to functional unit) switching manipulation and make the automatic stopping constant time lag (with reference to step S15 and S19) of motor 30, or respond this operation and make motor 30 stop (with reference to step S16), or its pattern is transferred to off mode thus forbids the automatic stopping (with reference to step S39) of motor 30.

In addition, also operating switch (being equivalent to functional unit) special in addition can be set in vehicle 10.Namely, ECU20 also can make the automatic stopping constant time lag (with reference to step S15 and S19) of motor 30 based on the operation of this dedicated operations switch by driver, or respond this operation and make motor 30 stop (with reference to step S16), or also this pattern can be transferred to off mode thus forbid the automatic stopping (with reference to step S39) of motor 30.This dedicated operations switch can be arranged respectively according to above-mentioned each delay disposal, stopping process and mode shifts process, also can implement above-mentioned each process by a switch.In addition, preferably by dedicated operations switch-linear hybrid near the handlebar of such as vehicle 10.

In the above-described first embodiment, based on the aperture of the throttle valve valve TV detected by throttle valve opening sensor 36, ECU20 determines whether that implementing throttle valve by driver operates (with reference to step S15), but the present invention is not limited to this decision method.

Such as, in the 11 variation, engine controlling unit 100 also can possess and is installed in vehicle 1010 and is connected to ECU20 in the mode that can communicate and the handle operation quantity sensor 50 detected the rotating operation amount of throttle valve handle 14.Now, in ECU20 step S15, can determine whether that implementing throttle valve operates based on the rotating operation amount of the throttle valve handle 14 detected by this handle operation quantity sensor 50.

In the respective embodiments described above, ECU20 is in the process of step S16 and S36, operation amount based on the rear brake detected by rear brake sensor 38 determines whether that the releasing being implemented rear brake by driver operates, but the present invention is not limited to this decision method.

Such as, as the 11 variation, ECU20 also can possess and is installed in vehicle 10, and is connected to ECU20 in the mode that can communicate, and exports the brake switch 52 (imaginary line with reference to Fig. 2) of ON/OFF signal according to the operation amount of rear brake.Now, ECU20 in the process of step S16 and S36, can determine whether based on the ON/OFF signal exported from brake switch 52 the releasing operation implementing rear brake.

As the 12 variation, ECU20 also such as can respond the pressing operation (open operation) of stop switch 24 and motor 30 is stopped in the process of step S16.In this case, ECU20 can according to the operating time of stop switch 24, that is, the compressing time of stop switch 24 distinguishes the stopping (the second engine stop) of the stopping (the first engine stop) of the motor 30 had nothing to do with idle stop and the motor 30 based on idle stop.

That is, the first engine stop is the engine stop (forcing to stop) of the operation of script-based stop switch 24, motor 30 also can not be made to restart even if implement throttle valve operation ECU20 afterwards.

On the other hand, the second engine stop is the engine stop based on idle stop, and when meeting the predetermined restart condition of throttle valve operation etc. afterwards, ECU20 drives starter 33 and motor 30 is restarted.Like this, by to utilize common stop switch 24 and to respond the operation of this stop switch 24 and the mode making motor 30 stop immediately being formed, can not special stop switch be set in addition and perform the second engine stop process, namely, motor 30 is stopped automatically, thus the complex structure of vehicle 10 can be avoided.

In addition, for the first engine stop of motor 30 and the switching of the second engine stop, do not need necessarily to implement according to the operating time of stop switch 24, can implement according to other mode of operation of stop switch 24 yet.Such as, the first engine stop can being switched to when the number of times of operation of stop switch 24 is more than pre-determined number, switching to the second engine stop when not reaching pre-determined number.

In the above-described first embodiment, ECU20 is in step S31, when operating based on the interim throttle valve by driver and set retard time, is set as the stand-by period (i.e. standby time T2) from implementing the operation of interim throttle valve to making motor 30 stop retard time, but the method for the setting of retard time in the present invention is not limited to the method.

Such as, as the 13 variation, ECU20 also can make standby time T1 originally (stand-by period from vehicle stops to making motor 30 stop) in step S31, and itself extends based on being operated by the interim throttle valve of driver, and the standby time T1 α this extended set as retard time.In addition in this case, the judgement that whether have passed through retard time is, whether reaches standby time T1 α to judge by the transit time TX stopping from vehicle.

Time showing portion 22 also can not carry out subtrahend display to the remaining time through standby time T1, T2.Such as, as the 14 variation, time showing portion 22 also such as can carry out addend display to the transit time TX from vehicle stopping.That is, as long as time showing portion 22 is to representing that the time through situation of standby time T1 and T2 shows, its display mode is any-mode.

As long as that is, structural element 22 or other structural element be as by standby time T1 and T2 through situation, driver is notified play a role through condition notification mechanism, then can form in any way.Such as, the structural element 22 strip display unit that also can show as the strip increasing the length along with standby time T1 and T2 respective process or reduce and being arranged in vehicle 10.In this case, strip display unit 22 can by the length change amount of this strip notify standby time T1 and T2 through situation.In addition, structural element 22 also can be by the indicator that through situation represent of light to standby time T1 and T2.In this case, indicator 22 also can change representing through situation standby time T1 and T2 of flash speed of light such as by exporting, thus to driver notify standby time T1 and T2 through situation.

Above-mentioned exemplified through condition notification mechanism 22 for resorting to the device of the vision of driver, but be not limited to said structure through condition notification mechanism 22.Such as, the mode through situation that also can export standby time T1 and T2 with the voice output utensil such as via loudspeaker etc. through condition notification mechanism 22 is formed.In this case, can by audio output device with sound export standby time T1 and T2 through situation, and then notify driver.

In the first above-mentioned mode of execution, ECU20 in step s 11 from vehicle 10 stops completely, from the speed vanishing of vehicle 10, namely come into effect the measurement of transit time TX, but the present invention is not limited to this structure.Such as, as the 15 variation, ECU20 also can when the speed of vehicle 10 is below predetermined value or the rotating speed of motor 30 be that the situation of below predetermined value is inferior, vehicle 10 comes into effect the measurement of transit time TX after arriving predetermined low speed state.

In the above-described first embodiment, for making the stopping constant time lag of motor 30 or making the self-braking operation of motor 30, might not need implementing during through standby time T1 stopping from vehicle.Such as, as the 16 variation, aforesaid operations also can, other timing enforcement medium in the traveling of vehicle 10.In this case, when use is equipped on the functional unit of vehicle 10 in advance, such as, as as shown in the 7th variation or the 9th variation, preferably when this functional unit is operated with the mode of operation of different from common mode of operation (impossible), be set to for making the operation of the stopping constant time lag of motor 30 or for making the self-braking operation of motor 30.If form in like fashion, even if then in the traveling of vehicle 10, when operating aforesaid operations parts with the mode of operation different from common mode of operation, ECU20 also can reliably identify its be stopping constant time lag for making motor 30 operation or for making the self-braking operation of motor 30.

In the above-described 2nd embodiment, ECU20, in step S31, when the speed of the vehicle 10 detected by vehicle speed sensor 35 reduces along with the process of time, be judged to be that vehicle 10 is in deceleration regime, but the present invention is not limited to this structure.Such as, as the 17 variation, ECU20 also can in step S31, when aperture vanishing (i.e. the full-shut position) of the throttle valve valve TV detected by throttle valve opening sensor 36, or when the aperture of throttle valve valve TV becomes below predetermined aperture, be judged to be that vehicle 10 is in deceleration regime.

In addition, as the 17 variation, ECU20 also can in step S31, when the speed of vehicle 10 to reduce along with the process of time and the aperture vanishing of throttle valve valve TV (or when becoming below predetermined aperture in the aperture of throttle valve valve TV), be judged to be that vehicle 10 is in deceleration regime.

Although in the above-described 2nd embodiment, ECU20 is in step S34, when the releasing of off mode, the aperture of the throttle valve valve TV detected from throttle valve opening sensor 36 becomes predetermined aperture (such as, predetermined threshold k 3) more than when, be judged to be that vehicle 10 has started to travel, but in the present invention, also can implement above-mentioned judgement with additive method.

Such as, as the 18 variation, ECU20 also in step S34, when the speed of the vehicle 10 detected from vehicle speed sensor 35 becomes more than predetermined speed, can judge that vehicle 10 has started to travel.In addition, ECU20 also in step S34, when the speed that determined the vehicle 10 detected by vehicle speed sensor 35 rises along with the process of time, can be judged to be that vehicle 10 has started to travel.And, ECU20 also can in step S34, become more than predetermined aperture in the aperture meeting throttle valve valve TV, the speed of vehicle 10 become more than predetermined speed, the speed of vehicle 10 rises along with the process of time, among at least any two conditions, be judged to be vehicle 10 started travel.

In the above-described 2nd embodiment, ECU20 in step s 30, based on cancel switch 26 operation and the automatic stopping of motor 30 is forbidden, but the present invention is not limited to this structure.Such as, as the 18 variation, ECU20 also can make the automatic stopping of motor 30 forbid based on the operation of other the functional unit (the 3rd functional unit) of stop switch 24, front brake bar 15, rear side brake rod 16 etc.That is, arbitrary functional unit can be established as in order to make the automatic stopping of motor 30 forbid operated functional unit.In this case, preferably when the 3rd functional unit is operated with the mode of operation of different from common mode of operation (impossible), the operation that above-mentioned automatic stopping is forbidden is set to.If form by this way, when the 3rd functional unit is operated in the mode different from common mode of operation, ECU20 reliably can identify that it is the operation that make the automatic stopping of motor 30 forbid.
