Pulley 50a is fixed to the input shaft 51 of hydraulic couplers 50, and extends between the pulley 22a of this pulley 50a and motor 22 with 23.By this structure, set up hydraulic couplers 50 can being passed to cooling fan 46 from the driving fluid such as power utilization such as silicone oil (driving oil) of motor 22 input.Fig. 2 is the structural drawing that the schematic construction of this hydraulic couplers 50 is shown.As shown in the figure, hydraulic couplers 50 comprises housing 54, dish 56, demarcation strip 58 and actuating unit 60.Cooling fan 46 is assemblied on the peripheral edge of housing 54, and housing 54 is supported on the input shaft 51 can freely rotating thereon via bearing 52.In addition, be accompanied by dish 56 in being contained in housing 54, dish 56 is fixed on the end of input shaft 51, drives oil with the power utilization that will input to input shaft 51 and is passed to housing 54.But demarcation strip 58 is accompanied by the separated by spaces in the housing 54 to the apotheca 61 of stores drive oil and the drive chamber 62 that holds dish 56, also is formed with supply orifice 58a, and it can be opened and oilyly be supplied to drive chamber 62 from apotheca 61 driving, perhaps can be closed.These supply orifices 58a in the demarcation strip 58 is opened and closed to actuating unit 60.
Be accompanied by on dish 56 peripheral part and be formed with concavo-convex rib 56a, similarly rib 63 also is formed on the inwall of cover 54a of housing 54.When cover 54a being assembled to main body 54b, the rib 56a of dish 56 and the rib 63 of cover 54a are meshing with each other, and stay predetermined gap between the two, form the maze trough as the transmission of torque part thus.Therefore, when driving state lower wall 56 that oil is injected into this maze trough and be rotated, can utilize the viscous resistance that drives oil to transmit rotating torques, thus drive shell 54 (and cooling fan 46) rotationally.
Actuating unit 60 comprises bimetallic devices 60a, and its direction of forward movement with respect to vehicle is arranged in the rear side of its front side and radiator 42.Supply orifice 58a in the demarcation strip 58 follows the distortion of this bimetallic devices 60a and opens and closes, and can regulate the amount of the driving oil of answering to drive chamber 62 from apotheca 61 thus.In other words, near the temperature of the ambient air bimetallic devices 60a (promptly, when the temperature of the wind by radiator 42) low, the supply orifice 58a of demarcation strip 58 closes because of the distortion of bimetallic devices 60a, and it is little to enter the quantitative change of driving oil of drive chamber 62 from apotheca 61 supplies thus.Therefore, from coiling 56 the diminishing of torque that are passed to housing 54.As a result, the rotating speed step-down of cooling fan 46.On the other hand, when near the temperature of the ambient air the bimetallic devices 60a uprised, the supply orifice 58a of demarcation strip 58 opened because of the distortion of bimetallic devices 60a, and the quantitative change of supplying the driving oil that enters drive chamber 62 from apotheca 61 is big.Therefore, big from coiling 56 to the change of housing 54 torque transmitted.As a result, the rotating speed of cooling fan 46 uprises.In this way, actuating unit 60 is regulated the rotating speed of cooling fan 46.

The basic controlling (idling stops control) that now explanation is had the vehicle that is used for present embodiment 20 of said structure.When satisfying predetermined stoppage condition, for example when vehicle stops, be accompanied by that accelerator pedal 83 is not operated and accelerator is in off status, brake petal 85 also is operated and break is in out state, and engine speed Ne is less than or equal to desired speed or the like, and then motor 22 stops automatically.When satisfying predetermined starting conditions, for example be accompanied by break and be in the off status accelerator and become out or the like, then be used to electric power from storage battery 38, motor 22 is started automatically by starting motor 28.
The work of vehicle 20 that now explanation is had the present embodiment of said structure.Fig. 3 is the flow chart that the example of the drive controlling routine of being carried out by the electronic control unit 70 of present embodiment is shown.Repeat this routine with predetermined period of time.
When carrying out this drive controlling routine, at first CPU 72 inputs by electronic control unit 70 are such as from the accelerator opening Acc of accelerator pedal position sensor 84, from the vehicle velocity V of vehicle speed sensor 88 and from the data (step S100) of the engine speed Ne of speed probe 25 etc.According to setting the target throttle valve opening TH that is used for motor 22 at the accelerator opening Acc of step S100 input
*Meanwhile, be automatic transmission 26 target setting change gear (step S110) according to accelerator opening Acc and vehicle velocity V.
Then, estimate the auxiliary unit energy consumption Pa (step S120) of driven auxiliary unit (for example cooling fan 46 and alternator 36 etc.) in the power that consumes from motor 22.The auxiliary unit energy consumption that figure 4 illustrates step S120 is estimated to handle.As shown in Figure 4, in estimation to this auxiliary unit energy consumption Pa, required data (step S122) are handled in input, for example from the engine speed Ne and the rotation speed of the fan of speed probe 47, and except cooling fan 46, consume from the energy consumption Px of the auxiliary unit of the power of motor 22 etc.Calculate pulley rotational speed N p (step S124) by making the engine speed Ne that in step S122, has imported multiply by conversion coefficient (pulley ratio) as the rotating speed of the input shaft 51 of hydraulic couplers 50 (that is pulley 50a).Estimate the fan energy Pf (step S126) of conduct according to the pulley rotational speed N p that in step S124, has calculated and according to the rotation speed of the fan Nf that has imported by the energy of cooling fan 46 consumption.And add that by the energy consumption Px that will import the fan energy Pf that has obtained in step S126 estimation sets auxiliary unit energy consumption Pa (step S128).Here, can obtain energy consumption Px by energy consumption phase Calais with each different auxiliary units.Can obtain the energy consumption of each auxiliary unit in the following manner.For example, detect the electric power that produces by alternator 36.Perhaps, for energy consumption, can use the value that depends on open/close state and engine speed Ne such as the auxiliary units such as compressor of water pump 44, energy the steering gear or air conditioner.In the present embodiment, for fan energy Pf, obtain the relation between pulley rotational speed N p, rotation speed of the fan Nf and the fan energy Pf in advance, and it is stored in ROM 74 as the mapping graph that is used for energy consumption estimation.More than supposition is set corresponding fan energy Pf by the mapping graph of storage when giving static pulley rotational speed N p and rotation speed of the fan Nf.Figure 5 illustrates the example of the above-mentioned mapping graph that is used to set fan energy.In Fig. 5, estimate fan energy Pf according to pulley rotational speed N p (engine speed Ne) and rotation speed of the fan Nf.Reason to this is based on following situation: the state that the rotation speed of the fan Nf corresponding with pulley rotational speed N p is subjected to hydraulic couplers 50 (promptly, be subjected to injecting the amount of the driving oil of drive chamber 62 from apotheca 61) control, and the state of hydraulic couplers 50 has great influence for fan energy Pf.
When estimating in this way to obtain auxiliary unit energy consumption Pa, estimate that by making the auxiliary unit energy consumption Pa that obtains is set to compensation aperture THset (step S130) divided by the value that the rotational speed N e of the motor of having imported obtains.Add target throttle valve opening TH by the compensation aperture Thset that will in step S130, set
*Come target throttle valve opening TH
*Compensate (step S140).In addition, be accompanied by this target throttle valve opening TH that in step S140, has been compensated by
*Motor 22 is carried out drive controlling, with automatic transmission 26 drive controlling to target speed change ratio gamma (step S150).This finishes routine then.Thus, can carry out the drive controlling that motor 22 is fit to, and no matter (that is fan energy Pf) size of auxiliary unit energy consumption Pa is how.In addition, can improve the driving sense of vehicle.For example, if when changing the gear of automatic transmission 26, adopt this class control, then can further improve the speed change sensation.
