It is more than to shake thereby, it is possible to the variable quantity F for confirming (judgement) in step S15 to be the revolving speed E of the output shaft 111 of engine 110 The state of the shaking of dynamic specified value R is when driving the Best Times of ancillary equipment 10, alternatively, reaching in step s 16 When capable of allowing to drive limit time (the allowing set value T) of ancillary equipment 10, start the driving of ancillary equipment 10.
Therefore, as shown in dotted line in Fig. 3 (a), vehicle 100 can be in the revolving speed E higher of the output shaft 111 of engine 110 And before being changed into reduction tendency or when its revolving speed E is in increase tendency, start the driving of ancillary equipment 10, can be avoided and start The revolving speed E of machine 110 sharply declines.
Thus, for example, vehicle 100 U can make when the revolving speed E of engine 110 is in and increases tendency as shown in Fig. 4 (c) The driving of ancillary equipment 10 starts, and can be turned the output shaft 111 of engine 110 using the load of the driving of ancillary equipment 10 The increase of fast E offsets and makes to change smoothing.Therefore, as shown in Fig. 4 (b), vehicle 100 can will not be due to ancillary equipment 10 The load of driving and the greater impact for making the degree slowed down increase (anxious swash slow down) and causing occupant that can experience, to start to assist The driving of equipment 10.
In this way, being detected in the Engine ECU 150 of present embodiment according to revolving speed (rotation speed) E of engine 110 The shaking of vehicle 100, adjustment starts the time of the driving of ancillary equipment 10, it is therefore not necessary to add as lock-up clutch Special control unit, in addition, the revolving speed E change dramatically of engine 110 will not be made and held with forming the impact that can pass to occupant The driving of beginning ancillary equipment 10.
As other forms of present embodiment, will be carried out as an example when the stopping of fuel injection in the present embodiment Illustrate, but not limited to this.For example, it is also possible to be executed according to fuel injection when accelerating.
In addition, also can be applied to when can be applied not only to start the driving of ancillary equipment 10 by ancillary equipment 10 When driving stops and disconnects it from engine 110.For example, it is also possible to be in contrast to this embodiment and turn in engine 110 The variable quantity F of fast E, which is less than when shaking specified value (example: the differential value of revolving speed is negative), to be stopped the driving of ancillary equipment 10 and makes it It is disconnected from engine 110, so that the revolving speed E of engine 110 does not steeply rise.
Moreover, not only can be from the revolving speed E of engine 110, it can also be from the rotating condition of stepless transmission 130, driving The direction of the shaking of the relationship export vehicle 100 of the revolving speed of the wheel speed and engine 110 of wheel 101, shaking volume, to adjust auxiliary The time of driving, the stopping of equipment 10.
Although disclosing embodiments of the present invention, those skilled in the art can add not departing from the scope of the present invention With change, this point is clear.Present claims are intended to comprising all this amendments and equivalent.
