Fig. 6 is to illustrate the action of device of the 1st embodiment of the present invention, the i.e. flow chart of the action of controller for shifting 84. About diagram program, at predetermined time intervals, such as 10msec make it be performed.In Fig. 6 flow chart (and flow process afterwards Figure) in, " S " expression processes step.

Described below, in S10, according to the output of displacement transducer 88, it is judged that (judgement) 4 gear engaging mechanisms 60, the current engaged gear (hereinafter referred to as " current shelves ") of the foundation in sleeve 60g, 62g, 64g, 66g of 62,64,66 The displacement of sleeve whether be more than gear deviation determining value, in other words, the movement of sleeve whether change or sleeve whether Move towards neutral position from extension file location.

Gear deviation determining value is set to represent at this sleeve (such as sleeve 60g) as shown in Figure 4 from hanging gear Put towards neutral position carry out displacement (movement) time, corresponding be worth with producing the displacement that gear departs from, specifically, be arranged on and become Whether produce between input speed NM and output speed NC/do not produce the marginal displacement (value of (e) of Fig. 4) of rotational difference with Between the displacement (value of (f) of Fig. 4) of sleeve and soldered tooth local engagement.

It addition, in the process of S10, the output of displacement transducer 88 can be substituted, and according to the 2nd speed probe 92 (or the 3rd speed probe 94) and the output of the 4th speed probe 96, directly calculate gear engaging mechanism 60,62,64,66 Rotational difference between input speed NM and output speed NC, sentences by being departed from the gear suitably set by the rotational difference calculated Determine rotating speed to compare, judge whether gear engaging mechanism is in gear and departs from.

But, by by the displacement that detects from displacement transducer 88 be set to than the above-mentioned rotational difference that produces Position more compares by hanging the gear deviation determining value of position of shelves side, judges that (detection) gear departs from, it is possible to rapidly Determine whether likely to produce rotational difference, the most whether should travel under current shelves.

When not being tooth for negative, i.e. displacement at the sleeve being judged as current engaged gear engaging mechanism in S10 When taking turns more than deviation determining value (less than gear deviation determining value) and do not occur gear to depart from, enter S12, carry out usual row Sail.That is, the sleeve of the current gear engaging mechanism engaged in 4 gear engaging mechanisms 60,62,64,66 does not produce tooth Wheel departs from, and therefore, proceeds the traveling under the gear (current shelves) set up by the sleeve of the gear engaging mechanism engaged.

On the other hand, when in S10 for affirmative, it is meant that the sleeve at the current gear engaging mechanism engaged creates Gear departs from, and variator T is in the state of the driving force not transmitting electromotor 10, therefore, enters S14, calculates target shift speed Shelves (hereinafter referred to as " next shelves "), enter S16, perform the pre-gear shift that next grade is carried out to this.

As it has been described above, in variator T, speed change is substantially at odd number shelves (1,3,5,7 speed) and even gear (2,4,6,8 speed) Between be alternately carried out, therefore, in S14, if current shelves are odd number shelves, then calculate target phase (next shelves) for rise 1 grade/ The even gear of 1 grade drops, or, if current shelves are even gear, then target phase (next shelves) is the odd number shelves rising 1 grade/fall 1 grade, In S16, according to target shift load, in the gear engaging mechanism 60,62,64,66 corresponding with next grade calculated The piston chamber of any one piston supplies the hydraulic pressure calculated, and performs to make sleeve 60g, 62g, 64g, 66g and the 1st secondary power shaft 20, any one in the 2nd secondary power shaft 22 engages the pre-gear shift of (engaging).
