In step S103, control said synchro 6 and carry out gear shift work, and control said first clutch 4 and second clutch 5 carries out synchronous working.Particularly; Control that concrete steps that said synchro 6 carries out gear shift work comprise that said synchro 6 separates with the first shifting gear group 7, said synchro 6 slides into the critical contact point that the predefined and said second shifting gear group 8 combines on said main shaft and carry out synchronization work, said synchro 6 combines with the second shifting gear group 8; It will be appreciated by those skilled in the art that this step can realize that the separation of synchro 6 and the mode that slides realize through the shift fork of controlling said synchro 6.The implementation of said concrete steps will be described in detail in following embodiment, not repeat them here.Further; Said first clutch 4 of said control and second clutch 5 carry out synchronous working; Promptly when said first clutch 4 and second clutch 5 after separatings; Just begin to regulate the rotating speed of the driving disc spacing pressing of said first clutch 4 and second clutch 5, and the driving disc spacing pressing of controlling said first clutch 4 moves to the critical contact point that combines with clutch plate, the driving disc spacing pressing of controlling said second clutch 5 moves to the critical contact point that combines with clutch plate.For example in the present embodiment; The rotating speed of the driving disc spacing pressing of said first clutch 4 and second clutch 5 is turned down; The rotating speed of driving disc spacing pressing that makes said first clutch 4 and second clutch 5 is near the rotating speed of clutch plate of response; Make the speed discrepancy of driving disc spacing pressing and corresponding clutch plate of said first clutch 4 less than first threshold, make the speed discrepancy of driving disc spacing pressing and corresponding clutch plate of said second clutch 5 less than the 3rd threshold value.It will be apparent to those skilled in the art that; Said first threshold and the 3rd threshold value are respectively less values for the rotating speed of the driving disc spacing pressing of said first clutch 4 and second clutch 5 and clutch plate; When the speed discrepancy of the driving disc spacing pressing of said first clutch 4 and second clutch 5 and corresponding clutch plate during respectively less than first threshold and the 3rd threshold value; Just can think very approaching of rotating speed of driving disc spacing pressing and corresponding clutch plate of said first clutch 4 and second clutch 5; In the time of can combining with corresponding clutch plate at the driving disc spacing pressing of first clutch described in the subsequent step 4 and second clutch 5; Make very little of impact of driving disc spacing pressing and corresponding clutch plate of said first clutch 4 and second clutch 5, improved the shift quality of gear-shifting control method of the present invention.Further, said first threshold can equate with the value of said the 3rd threshold value, also can get different numerical according to self-characteristic.It will be appreciated by those skilled in the art that said critical contact point can confirm according to the practical implementation needs, for example preferably, is that the inner conical surface of synchro 6 contacts the transformation point that produces friction with gear-wheel gear-ring male cone (strobilus masculinus) to be joined.Further, it will be appreciated by those skilled in the art that the setting of said critical contact point does not influence flesh and blood of the present invention, do not repeat them here.

Further, in this step S103, carrying out when the said synchro 6 of above-mentioned control carries out gear shift work, controlling said first clutch 4 and second clutch 5 carries out synchronous working.Particularly; It will be apparent to those skilled in the art that; Control said synchro 6 and carry out gear shift work and carry out two control processs of synchronous working with control said first clutch 4 and second clutch 5 and preferably carry out simultaneously, thereby can utilize the time of this control process fully, after this step S103 is finished; Accomplished the combination work dead work before of said first clutch 4 of following control and second clutch 5, do not repeated them here.Suboptimum ground, the said synchro 6 of said control carry out gear shift work and can successively carry out with two control processs that control said first clutch 4 and second clutch 5 carry out synchronous working.

And then execution in step S104, control said first clutch 4 and second clutch 5 combinations, the driving disc spacing pressing of promptly controlling said first clutch 4 combines with clutch plate, and the driving disc spacing pressing of controlling said second clutch 5 combines with clutch plate.Simultaneously, in the process that said first clutch 4 combines, control progressively output torque of said first motor 2, the pressure of controlling said first clutch 4 simultaneously is to regulate the torque transmitting ability of said first clutch 4; In the process that said second clutch 5 combines, control progressively output torque of said second motor 3, the pressure of controlling said second clutch 5 simultaneously is to regulate the torque transmitting ability of said second clutch 5.Owing in step S103, accomplished the dead work before the combination work of controlling said first clutch 4 and second clutch 5, so in this step S104, said first clutch 4 and second clutch 5 can successfully be accomplished combination work.It will be appreciated by those skilled in the art that the first clutch 4 of this step S104 description and the combination of second clutch 5 are anti-processes that first clutch 4 described in the above-mentioned steps S102 and second clutch 5 separate.After this step S104 carries out; Accomplished the connection work of machinery of the power transmission path of said second gear; The power of said propulsion source transmission can not repeat them here through said power-transfer clutch, synchro 6, the second shifting gear group 8 and diff 9 to automotive wheel 20 transmission.

Further; It will be appreciated by those skilled in the art that described in the foregoing description and the variant first threshold, second threshold value, the 3rd threshold value, the 4th threshold value and critical speed preferably according to the present invention applied hybrid power to drive the structure itself of automobile of automobile or other types definite.For example, preferably, the setting of first threshold values is based on that synchro bears the ability of shift impact and based on the requirement of shift quality.For example, based on to the synchro requirement in service life, the inertial impact force during gearshift can not be greater than 100 newton meteies, and based on the requirement of shift quality, the inertial impact force during gearshift can not be greater than 40 newton meteies simultaneously.Impulsive force when shifting gears like this can not be greater than 40 newton meteies.In the inertia characteristic according to synchro, first threshold values is set to 400 rpms.Again for example, the setting of the 3rd threshold values is preferably based on the requirement to the gearshift time, and the setting of the 4th threshold values is preferably born the ability of moment fluctuating range based on synchro and based on the requirement of shift quality.Those skilled in the art can be achieved with reference to the foregoing description and prior art, do not repeat them here.Again for example; Preferably said second threshold values depends primarily on the requirement to the gearshift time; And can set: for example preferably according to different enforcement needs; When from said first gear switch to said second gear, if hope in 400 milliseconds, to accomplish, then said second threshold value preferentially is set in 20 milliseconds to 50 milliseconds interval; And in a variant, when from said first gear switch to said second gear, if hope in 350 milliseconds of seconds, to accomplish, then said second threshold value preferentially is set in 20 milliseconds to 40 milliseconds interval, does not repeat them here.

Said second threshold value and the 4th threshold value are the tachometer values separately of the driving disc spacing pressing of the driving disc spacing pressing of driving disc spacing pressing and 3 pairs of said second clutch 5 of said second motor of 2 pairs of said firsts clutch 4 of said first motor of making that

first clutch

4 and 5 speed adjustment times of second clutch are the shortest first clutch 4 and the second clutch 5 when Torque Control converts rotating speed control into.Preferably, in the present invention, the span of said second threshold value is 0 to 400 rpm.The span of said the 4th threshold value is 0 to 400 rpm.
