At this, the transmitting torque capacity coefficient (τ) of fluid coupling is described with reference to Fig. 3.Fig. 3 for the ratio (ω 1/ ω 2) of pump impeller rotating speed (ω 1) and the secondary speed (ω 2) of expression fluid coupling, be the transmitting torque capacity coefficient chart that concerns between speed ratio (e) and the transmitting torque capacity coefficient (τ).Obtain, in addition by experiment corresponding to the transmitting torque capacity coefficient (τ) of speed ratio (e) in this transmitting torque capacity coefficient chart, in Fig. 3, the cruising zone that to be vehicle driving apparatus shown in Figure 1 driven by motor 2, the interval of speed ratio (e) from 0 to 1, speed ratio (e) are that the zone 1 or more is to be the engine braking zone of speed changer 5 from driving motor 2 by wheel side.In addition, speed ratio (e) is the pump impeller and the rotating one another in opposite directions zone of turbine of fluid coupling in the zone below 0.
As mentioned above, owing to can obtain the transmitting torque (Tf) of fluid coupling by the transmitting torque capacity coefficient (τ) of fluid coupling and pump impeller rotating speed (ω 1), therefore can judge fluid coupling and have function as the torque sensor of friction clutch according to above-mentioned formula 1.The present invention holds the transmitting torque (Ta) of friction clutch by the transmitting torque (Tf) of obtaining fluid coupling, thereby determines the binding capacity or the engaging speed of friction clutch.
Below, the sequence of operation of the clutch of control unit 20 control in the device for controlling friction clutch of the above-mentioned vehicle driving apparatus of flowchart text that reference is shown in Figure 2.
Wet-type multi-disc friction clutch 4 disconnects when speed changer 5 variable speed operations.Promptly, when beginning switch 12 input speed change commencing signals from speed change, Wet-type multi-disc friction clutch 4 disconnects, and after this carries out the variable speed operation of speed changer 5, before the detecting switch 13 input variable speed operation end signals that are over from gear shift, Wet-type multi-disc friction clutch 4 is kept off state.
Clutch rotational speed poor (absolute value) is greater than the occasion of 100rpm in step S1, owing to when the Wet-type multi-disc friction clutch directly engages, can impact, so control unit 20 is carried out half Engagement Control below step S6.In step S6, control unit 20 is obtained target transmitting torque (Ta) corresponding to accelerator opening according to the testing signal of accelerator pedal sensor 11.Promptly, the target transmitting torque control diagram of the target transmitting torque (Ta) that storage is set corresponding to accelerator opening as shown in Figure 4 on the ROM (read-only memory) (ROM) 202 of control unit 20 is obtained target transmitting torque (Ta) corresponding to accelerator opening by this target transmitting torque control diagram.
As mentioned above after obtaining target transmitting torque (Ta), control unit 20 enters among the step S7, obtain by engine rotation speed sensor 7 detected pump impeller rotating speeds (ω 1) with by the ratio (ω 2/ ω 1) of clutch input element rotating speed detecting sensor 8 detected secondary speeds (ω 2), i.e. speed ratio (e).After obtaining speed ratio (e), control unit 20 enters among the step S8, obtains the transmitting torque capacity coefficient (τ) corresponding to speed ratio (e).Promptly, go up transmitting torque capacity coefficient (τ) is set in storage as shown in Figure 3 corresponding to speed ratio (e) transmitting torque capacity coefficient chart in the ROM (read-only memory) (ROM) of control unit 20, obtain transmitting torque capacity coefficient (τ) corresponding to speed ratio (e) by this transmitting torque capacity coefficient chart.
Then, control unit 20 enters among the step S9, calculates transmitting torque (Tf) (Tf=τ * { (ω 1) of fluid coupling 3
2/ 10
6).And, control unit enters among the step S10, according to the transmitting torque (Tf) of the target transmitting torque of in above-mentioned steps S8, obtaining (Ta), obtain the dutycycle (R) (R=R+ (Ta-Tf) C2) of electromagnetic switching valve 67 (V1) being carried out duty control with the fluid coupling of in above-mentioned steps S9, obtaining 3.Finding the solution this dutycycle) R (formula in, C2 is positive constant.That is, on dutycycle (R) last time, increase be multiply by the value ((Ta-Tf) C2) that positive constant C 2 is calculated by the difference of the transmitting torque (Tf) of target transmitting torque (Ta) and fluid coupling 3, thereby obtains this dutycycle (R).Initial dutycycle (R) is that the difference by the transmitting torque (Tf) of target transmitting torque (Ta) and fluid coupling 3 multiply by the value ((Ta-Tf) C2) that positive constant C 2 is calculated.After obtaining dutycycle (R), control unit 20 enters among the step S5 like this, controls electromagnetic switching valve 67 (V1) according to the dutycycle of obtaining in above-mentioned steps S10 (R).In addition, because the oil pressure in the hydraulic chamber 46 of above-mentioned dutycycle (R) and Wet-type multi-disc friction clutch 4 is suitable, therefore the dutycycle of obtaining according to the target transmitting torque (Ta) and the difference of the transmitting torque (Tf) of fluid coupling 3 (R) just is equivalent to the transmitting torque of Wet-type multi-disc friction clutch 4.As mentioned above, carry out half Engagement Control, when clutch rotational speed in above-mentioned steps S1 poor (absolute value) when 100m is following, even can not produce impact because Wet-type multi-disc friction clutch 4 directly engages yet, therefore control unit 20 is carried out above-mentioned steps S1～S5, the transmitting torque of Wet-type multi-disc friction clutch 4 can be brought up to and control the biglyyest.
More than, the present invention has been described in accordance with the embodiments illustrated, but the present invention is not only limited to described embodiment, in the scope of the technology of the present invention thought, can do all distortion.For example, in illustrated embodiment, though as friction clutch expression be the example that adopts the Wet-type multi-disc friction clutch, adopt the vehicle driving apparatus of dry type shell fragment friction clutch also to be applicable to the present invention.In addition, the present invention also is applicable to the vehicle driving apparatus of equipment torque converter (torque-converters).
