The driven by power that motor generator 4 is supplied from accumulator 7, thus rotates as the output shaft making electromotor 2 Motor function.It addition, motor generator 4 is driven by the output shaft of electromotor 2, thus as generating, accumulator 7 is filled The electromotor function of the electric power of electricity.

ECU6 is made up of computer unit, and above computer unit possesses: CPU (Central Processing Unit: CPU), RAM (Random Access Memory: random access memory), ROM (Read Only Memory: Read only memory), preserve backup the flash memory of data etc., input port and output port.

In store various constants or various mappings etc. and be used for making this computer unit make in the ROM of computer unit Program for ECU6 function.That is, the program that CPU is preserved by ROM with RAM for operating area execution, thus this computer list Unit is as the ECU6 function of present embodiment.

The input port of ECU6 is connected to various sensor class, and above-mentioned various sensor classes include the speed detecting vehicle 1 Vehicle speed sensor 11, the gear ratio sensor 12 of gear ratio of detection variator 5 and detection accumulator 7 in flow into, flow out The current sensor 13 of electric current.

Gear ratio sensor 12 detects the power shaft of such as variator 5 and the rotary speed of output shaft.ECU6 is according to by becoming The ratio of the power shaft of the variator 5 that speed ratio sensor 12 detects and the rotary speed of output shaft calculates the gear ratio of variator 5.

The output port of ECU6 is connected to motor generator 4 and includes supplying electromotor 2 fuel injector 21 of fuel Various control object classes.ECU6 controls various control object classes based on the information obtained from various sensor classes.

Such as ECU6 has as stopping when vehicle 1 slows down supplying fuel to electromotor 2 until the speed of vehicle 1 becomes The fuel supply of regulation recovers the function of the fuel supply stop 30 of below speed.It is to start sending out that fuel supply recovers speed Motivation 2 supplies the speed of fuel so that electromotor 2 will not stall, its value is beforehand through the appropriate value that determines of experiment.

ECU6 constitutes generation power control portion 31, and above-mentioned generation power control portion 31 controls to be come by the output of electromotor 2 Drive motor generator 4 thus the electric power that produces and kinetic energy regeneration when being made vehicle 1 slow down by motor generator 4 thus produce Electric power.

Such as, ECU6 controls the exciting current for driving motor generator 4, thus controls to be produced by motor generator 4 The voltage of electric power.

When ECU6 slows down with vehicle 1, the speed of vehicle 1 becomes the regeneration restriction being set higher than fuel supply recovery speed It is condition below speed, reduces the voltage of the electric power regenerated by motor generator 4.

In detail, ECU6 with vehicle 1 slow down time vehicle 1 speed become regeneration restricted speed below as condition, reduce The voltage of the electric power regenerated by motor generator 4 so that this voltage becomes the speed of vehicle 1 and becomes fuel supply when recovering speed Target voltage.

The gear of the in store variator of ROM 5 of ECU6 reflects than the regeneration restricted speed being mapped with regeneration restricted speed Penetrate.ECU6 constitutes regeneration restricted speed configuration part 32, and above-mentioned regeneration restricted speed configuration part 32 maps with reference to regeneration restricted speed, And the gear of the variator 5 obtained according to the testing result from gear ratio sensor 12 is than determining regeneration restricted speed.

In the case of so when vehicle 1 slows down, the speed of vehicle 1 is higher than regeneration restricted speed, ECU6 allows based on electronic The generating of the regeneration of electromotor 4, is set to substantial maximum by the exciting current of motor generator 4, motor generator 4 make Kinetic energy when vehicle 1 slows down regenerates and generates electricity.

On the other hand, in the case of when vehicle 1 slows down, the speed of vehicle 1 is below regeneration restricted speed, ECU6 limits The generating of regeneration based on motor generator 4, and the exciting current of motor generator 4, control is controlled according to the operating condition of vehicle 1 The voltage of the electric power that system is produced by motor generator 4 so that this voltage becomes the speed of vehicle 1 and becomes fuel supply recovery speed Time target voltage.

Illustrate that the regenerative electric power that the ECU6 of above-mentioned composition is carried out allows acts of determination with reference to Fig. 2.Additionally, from the starting of ECU6 The regenerative electric power repeating following description till being accomplished to stop allows acts of determination.

First, during ECU6 judges whether the fuel cut-off being off that electromotor 2 is supplied fuel (step S1).It is being judged as Be in fuel cut-off in the case of, ECU6 maps with reference to regeneration restricted speed, and ties according to from the detection of gear ratio sensor 12 The gear of the variator 5 that fruit obtains ratio determines regeneration restricted speed (step S2).

Then, ECU6 judges whether the speed detected by vehicle speed sensor 11 is below regeneration restricted speed (step S3).Be judged as in step sl be not in fuel cut-off in the case of, or be judged as in step s3 by vehicle speed sensor 11 In the case of the speed detected is below regeneration restricted speed, ECU6 enters and limits sending out of regeneration based on motor generator 4 The regenerative electric power unrestricted model (step S4) of electricity, allows acts of determination to terminate regenerative electric power.

In step s3, it is being judged as that the speed detected by vehicle speed sensor 11 is not the feelings of below regeneration restricted speed Under condition, ECU6 enters the regenerative electric power of the generating allowing regeneration based on motor generator 4 and allows pattern (step S5), will regeneration Generating allows acts of determination to terminate.

It follows that the regenerative electric power execution action that ECU6 is carried out is described with reference to Fig. 3.Additionally, the regenerative electric power of following description Execution action both can be performed by ECU6 after allowing acts of determination performing the regenerative electric power with reference to Fig. 2 explanation, it is also possible to Regenerative electric power allows acts of determination to be repeated by ECU6 concurrently.

First, ECU6 judges whether it is that regenerative electric power allows pattern (step S11).Mould is allowed being judged as YES regenerative electric power In the case of formula, the exciting current of motor generator 4 as substantial maximum, is performed to be made by motor generator 4 by ECU6 The regenerative electric power (step S12) of kinetic energy regeneration when vehicle 1 slows down, performs release by regenerative electric power.

In the case of being judged as not being regenerative electric power permission pattern, ECU6 limits regeneration based on motor generator 4 Generating, controls the exciting current of motor generator 4 according to the operating condition of vehicle 1, performs what control was produced by motor generator 4 The weak generating of the voltage of electric power so that this voltage becomes the speed of vehicle 1 and becomes target voltage when fuel supply recovers speed (step S13), performs release by regenerative electric power.

Illustrate that regenerative electric power described above allows acts of determination and the effect of regenerative electric power execution action with reference to Fig. 4.

In the coordinate diagram represented by reference 50, the longitudinal axis represents that speed, transverse axis represent the moment.By reference 51 In the coordinate diagram represented, the longitudinal axis represents the voltage of the electric power produced by motor generator 4, and transverse axis represents the moment.It addition, use accompanying drawing The dotted line that labelling 52 represents is owing to being comparison other, so representing the electric power produced in existing control by motor generator 4 The change of voltage.

Fig. 4 slows down from vehicle 1 and performs the state of fuel cut-off and starts to represent.That is, from the figure more forward than moment t1 In the moment, vehicle 1 slows down, and performs fuel cut-off.

At moment t1, if the speed of vehicle 1 becomes below regeneration restricted speed, then ECU6 allows pattern from regenerative electric power Become regenerative electric power unrestricted model, control the voltage of the electric power produced by motor generator 4 so that this voltage becomes at moment t2 The speed of vehicle 1 becomes target voltage during fuel supply recovery speed.

In order to prevent the variation of torque that the variation drastically of load of electrical generation that motor generator 4 brings causes, ECU6 leads to Crossing integration control makes the voltage of the electric power produced by motor generator 4 move closer to target voltage.

As used shown in arrow 53 in the diagram, when the speed at moment t2 vehicle 1 becomes fuel supply recovery speed, with Existing control is compared, motor generator 4 the voltage step-down of the electric power produced, therefore when stopped fuel cut-off, in order to The amount maintaining the fuel required for the voltage of the electric power produced by motor generator 4 reduces.

As it appears from the above, in the present embodiment, become with the speed of vehicle 1 when vehicle 1 slows down and be set higher than fuel It is condition that supply recovers below the regeneration restricted speed of speed, reduces the voltage of the electric power regenerated by motor generator 4.

Particularly, in the present embodiment, become with the speed of vehicle 1 when vehicle 1 slows down be set higher than fuel supply Should recover below the regeneration restricted speed of speed is condition, reduces the voltage of the electric power regenerated by motor generator 4 so that this electricity Press to the speed of vehicle 1 and become target voltage when fuel supply recovers speed.

Therefore, in the present embodiment, when stopped fuel cut-off, it is possible to reduce to be produced by motor generator 4 The voltage of raw electric power is set to the amount of the fuel required for target voltage, and becomes fuel supply in the speed of vehicle 1 and recover Speed and electromotor 2 can suppress the variation of load when starting idling.

It addition, in the present embodiment, regenerate restricted speed according to the gear of variator 5 than setting, therefore, it is possible to relatively Gear in variator 5 is set as optimum than by regeneration restricted speed.

(the 2nd embodiment)

Second embodiment of the present invention, illustrates the difference with the 1st embodiment of the present invention.Additionally, this enforcement Mode can be realized by the hardware composition identical with the 1st embodiment of the present invention, is the most also reference Fig. 1, and one Limit explanation present embodiment.

The program preserved by the ROM of ECU6 of present embodiment is different from the 1st embodiment of the present invention.Specifically, In the present embodiment, ECU6 has following function in addition to the function that the ECU6 of the 1st embodiment of the present invention is had: When vehicle 1 slows down, the speed of vehicle 1 is below regeneration restricted speed and the charge capacity of accumulator 7 is below regulation amount of savings, In the case of i.e. Generation Control execution condition is invalid, forbid that motor generator 4 generates electricity.Regulation amount of savings is beforehand through experiment The appropriate value determined.

In the present embodiment, the accumulative electric current detected by current sensor 13 of ECU6, thus calculate the storage of accumulator 7 Electricity.

The regenerative electric power carried out about the ECU6 of above-mentioned composition allows acts of determination, with the regenerative electric power with reference to Fig. 2 explanation Permission acts of determination is identical, therefore omits the description.

It follows that the regenerative electric power execution action that ECU6 is carried out is described with reference to Fig. 5.Additionally, the regenerative electric power of following description Execution action can allow be performed by ECU6 after acts of determination performing the regenerative electric power with reference to Fig. 2 explanation, it is also possible to again Hair growth promoting electricity allows acts of determination to be repeated by ECU6 concurrently.

First, ECU6 judges whether it is that regenerative electric power allows pattern (step S21).Mould is allowed being judged as YES regenerative electric power In the case of formula, the exciting current of motor generator 4 as substantial maximum, is performed to be made by motor generator 4 by ECU6 The regenerative electric power (step S22) of kinetic energy regeneration when vehicle 1 slows down, performs release by regenerative electric power.

In the case of being judged as not being regenerative electric power permission pattern, ECU6 judges that Generation Control performs whether condition is set up (step S23).In the case of being judged as that Generation Control performs condition establishment, ECU6 limits regeneration based on motor generator 4 Generating, control the exciting current of motor generator 4 according to the operating condition of vehicle 1, perform to control to be produced by motor generator 4 The weak generating of voltage of electric power so that this voltage becomes the speed of vehicle 1 and becomes target electricity when fuel supply recovers speed Pressure (step S24), performs release by regenerative electric power.

Be judged as Generation Control perform condition invalid in the case of, ECU6 forbids being generated electricity (step by motor generator 4 S25), regenerative electric power is performed release.
