Abstract
To solve problems in a clutch controller applying a friction-type clutch and connecting and disconnecting the clutch by both of the manual clutch control and the automatic clutch control, that the manual control or the automatic control is determined on the basis of a car speed, or the operation of a switch, and the manual clutch control is not executed only by depressing a clutch pedal by a driver. A controller for automatic clutch control is provided with a clutch pedal detecting signal minimum value storing part for updating and storing a minimum value (SMIN) from a clutch pedal position sensor , and a depressing will confirmation value part storing a value (alpha ) capable of confirming whether the depressing is executed with the depressing will from a fully contacting point or not. When the detection signal from the clutch pedal position sensor is more than SMIN +alpha , the automatic clutch control is forbidden, and the automatic clutch control is permitted in a case excluding the above case.
Description
Technical field
The present invention relates to a kind of clutch control device, use the friction type power-transfer clutch, no matter still all can make its clutch with the self-acting clutch mode with artificial clutch control mode as vehicular clutch.
Background technology
Use the friction type power-transfer clutch as vehicular clutch, no matter use artificial clutch control mode (controlling) still all can make the clutch control device of its clutch with the self-acting clutch mode with pedal of clutch, if carry out two kinds of control actions simultaneously, then can cause control chaotic, so, for avoiding confusion, must decision when adopt which kind of mode.Past, decide which kind of control method of employing according to speed of a motor vehicle speed, perhaps which kind of method the operation by change-over swith decides.
When deciding according to speed of a motor vehicle speed, for example, adopt manual clutch's control method under the speed of a motor vehicle condition before the affirmation starting-up action is finished, speed of a motor vehicle condition after this adopts the self-acting clutch control method.And, when the operation by change-over swith decides control method, be switched on or switched off change-over swith by chaufeur, select certain control method.
The clutch control device in above-mentioned past according to vehicle running state, can not adopt the desirable clutch control method of chaufeur sometimes, perhaps is forced to carry out not smoothly the operation bidirectional beyond the clutch operating.
If decide control method according to speed of a motor vehicle speed, promptly before playing EOS, adopt manual clutch's control, adopt self-acting clutch control then, so, usually in the process of moving, no matter how to want to adopt the manual clutch to control also all be impossible to chaufeur.
And, select the form of control method with change-over swith, must be before the operated clutch pedal operation change-over swith earlier.But the operation of change-over swith being carried out break-make is not the operation that can carry out in the clutch operating flow process of ordinary practice, but is another kind of independently not smoothly operation fully from clutch operating, is the operation that must especially carry out.Therefore, will increase the burden of chaufeur, be disadvantageous from the viewpoint of being convenient to and simplify driver behavior.
Summary of the invention
The objective of the invention is to address the above problem.
In order to address the above problem, the invention provides a kind of like this clutch control device, promptly no matter be that slave controller sends control signal to the power-transfer clutch automatic controls and carries out self-acting clutch control, still the pedal of clutch that tramps with one's feet carries out manual clutch's control, all can control the clutch of the friction type power-transfer clutch.In this clutch control device, in controller, be provided with:
Pedal of clutch detection signal minimum value storage part under the situation of detection signal less than storing value from the clutch pedal position sensor, deducts storing value; And
Tread in consciousness affirmation value portion, be used for storage and tread in consciousness affirmation value, this treads in consciousness affirmation value can confirm whether chaufeur has the consciousness of stepping on from the full engagement point of pedal of clutch and also tramp with one's feet down.
From the detection signal of clutch pedal position sensor greater than the value of above-mentioned pedal of clutch detection signal minimum value storage part with step under the situation of consciousness affirmation value sum, forbid self-acting clutch control; Allow self-acting clutch control in other cases.
Contain from the minimum value in the detection signal of clutch pedal position sensor at pedal of clutch detection signal minimum value storage part internal memory.This minimum value can only be the pedal of clutch detected signal value at the full engagement point place of pedal of clutch.That is to say that even at when maintenance reline the clutch pedal etc., part has under the situation such as error, also can access the pedal of clutch detection signal that reflects actual clutch full engagement point position all the time.
Because when speed change etc. needs control clutch, the pedal of clutch detection signal that detects adds under the situation of the value of stepping on consciousness affirmation value α greater than above-mentioned minimum value, carry out manual clutch's control, otherwise carry out self-acting clutch control, so, in the clutch operating flow process of the usual custom of chaufeur, adopt the desirable control method of chaufeur naturally.

The specific embodiment
Fig. 1 is the frame assumption diagram of clutch control device of the present invention.In Fig. 1, the 1st, Das Gaspedal, the 2nd, throttle sensor, the 3rd, shifter bar, the 4th, controller, the 5th, pedal of clutch, 5S is the clutch pedal position sensor, the 6th, and driving engine, the 7th, engine rotation sensor, the 8th, clutch stroke sensor, the 9th, gear position sensor, the 10th, change gear transmission, the 11st, car speed sensor, the 12nd, power-transfer clutch, the 13rd, change-speed box, the 14th, transmission shaft, the 15th, oil pressure pipe, the 16th, power-transfer clutch driver, the 17th, air apparatus for controlling of supply, the 18th, air bellow, the 19th, air pipe, the 41st, self-acting clutch control mandatory forbidding sign, the 42nd, pedal of clutch detection signal minimum value storage part, the 43rd, tread in consciousness affirmation value portion.
Driving engine 6 can be a diesel motor, also engine petrol.
The automatic guidance of power-transfer clutch 12 carries out (constituting clutch control mechanism by these parts) by air apparatus for controlling of supply 17, power-transfer clutch driver 16.The manual control of power-transfer clutch 12 is undertaken by the operation of pedal of clutch 5.The operation of pedal of clutch 5 is delivered on the power-transfer clutch driver 16 by the oil pressure of oil pressure pipe 15, and at this moment, the operation of pedal of clutch 5 control has precedence over self-acting clutch control.Whenever that is to say that in the present invention, under the situation of driver's operation pedal of clutch 5, (when being starting or when travelling) all carries out manual clutch's control.
Being controlled at after change gear transmission 10 sends instruction of change-speed box 13 carried out.The drive source of change gear transmission 10 and power-transfer clutch driver 16 adopts the air of supplying with from air bellow 18.
It is important in this that how to judge whether chaufeur is operated pedal of clutch 5.Whether that says here operates, and yes judges whether degree that pin is stepped on has reached chaufeur and had a mind to step on the degree that Shi Suoneng reaches.
Chaufeur is being not intended to step on but does not note pin has been put on the pedal of clutch 5 in the process of pin activity, or stepped on pedal 5 gently because of the bad habit of chaufeur, so must judge, so that these situations do not belong in the situation of power-transfer clutch having been carried out operation.
This judgement might not be easy, but the present invention can accurately judge.Below it is elaborated.
Fig. 3 is the figure of the characteristic of expression clutch pedal position sensor 5S.Wherein abscissa is represented the position of stepping on of pedal of clutch, P
ABe to leave point (clutch pedal position when pedal of clutch 5 has been treaded in the innermost), P fully
BBe full chalaza (clutch pedal position when pedal of clutch 5 is not stepped on).Ordinate is represented pedal of clutch detection signal (from the detection signal of clutch pedal position sensor 5S), S
ABe the detection signal of standard-sized sheet point, S
AIt is the detection signal of full chalaza.The line of point of connection A, B is a characteristic curve, the some A, B be with entirely from a P
A, full chalaza P
BPoint on the corresponding curve.
So, it is believed that, in advance S
BValue stores in the controller 4, makes detection signal and S from clutch pedal position sensor 5S
BCompare, if greater than S
B, then can be judged as pedal of clutch 5 has been carried out treading in operation; If less than S
B, then can be judged as and tread in operation.
But,, may judge rightly out hardly in this way and whether pedal of clutch 5 be operated owing to there is following situation.That is, because there is error in used detecting element characteristic among the clutch pedal position sensor 5S, and the link mechanism relevant with clutch pedal position sensor 5S have error, so be full chalaza P in the position that treads in of pedal of clutch 5
BState under, the value that actual detected goes out mostly not necessarily with the value S that is stored in separately in the controller 4
BConsistent.And numerical value changes owing to reason reline the clutch pedal 5 such as car inspection and maintenance or when regulating gap value, and former different, and with S
BConsistent possibility is very little.
Therefore, the present invention operates pedal of clutch 5 consciously in order to judge whether, has invented a kind of criterion value that treads in especially, when the pedal of clutch detection signal surpasses this standard value, forbid self-acting clutch control, only allow the manual clutch to control.
What is called treads in the criterion value and is meant the value (S that is arranged on the pedal of clutch detection signal minimum value storage part 42 in the controller 4
Min) and tread in the value (S of value (α) the addition gained of consciousness affirmation value portion 43
Min+ α).
In pedal of clutch detection signal minimum value storage part 42, when no matter being starting or when travelling, in a word, if just reduce this value when the pedal of clutch detection signal of sending here from clutch pedal position sensor 5S is less than the value of wherein storage at every turn.Carry out so repeatedly, can store minimum value (S at last
Min).This minimum value just can only become the full chalaza P of the actual clutch pedal state that meets this vehicle
BOn detection signal.
The value (α) that treads in consciousness affirmation value portion 43 is the value that provides in advance, and its size is under the situation that chaufeur treads in from full chalaza consciously, minimum for and the corresponding signal value of the amount of treading in that will tread in.This can wait by experiment and obtain.
Fig. 2 is the diagram of circuit of explanation clutch control of the present invention.
The 1st step ... read in pedal of clutch detection signal S from treading in criterion value 5S.
The 2nd step ... check that whether pedal of clutch detection signal S is greater than treading in criterion value (S
Min+ α).
The 3rd step ... if greater than, so just can judge and should carry out manual clutch's control, treaded in pedal of clutch consciously, so self-acting clutch control mandatory forbidding sign 41 is forbidden self-acting clutch control for connecting (ON).
The 4th step ... pedal of clutch detection signal S is for treading in criterion value (S when the 2nd step
Min+ α) under the following situation, can judge is to be not intended to carry out manual clutch's control, so, should allow self-acting clutch control, self-acting clutch control mandatory forbidding sign 41 is for cutting off (OFF).
The 5th step ... inspection at detected pedal of clutch detection signal S of the 1st step whether less than the pedal of clutch detection signal minimum value S that is stored in the pedal of clutch detection signal minimum value storage part 42 now
Min
The 6th step ... when less than pedal of clutch detection signal minimum value S
MinThe time, reduce pedal of clutch detection signal minimum value S
MinThat is to say, be updated to value (1 unit of the minimum when a so-called unit is meant the value that changes pedal of clutch detection signal minimum value storage part 42 that has only reduced a unit here.For example when constituting an one counting) with counting machine.
Do not replace immediately for detected little pedal of clutch detection signal S, its reason is as follows.Because sneak into certain eventuality such as noise, the little value of inconceivability may appear in pedal of clutch detection signal S.If just it is upgraded during this reason caused little value, so, can cause later control mistake.
Therefore, even if detected little value, also be pedal of clutch detection signal minimum value S
MinRenewal amount only remain in 1 unit.If owing to noise has detected the little value of eventuality, so, when carrying out next control flow, pedal of clutch detection signal S returns on the common value, so, at this moment upgrade.That is to say,, its influence that causes is remained in 1 minimum unit even produced little detection signal accidentally.
And, in above-mentioned example, utilize this software approach of sign, carry out forbidding or allowing of self-acting clutch control, but also can adopt hardware approach to carry out.
As mentioned above, if adopt clutch control device of the present invention, then when and need carry out clutch control the time for speed change etc., if chaufeur is wanted to carry out manual clutch's control and has been stepped on pedal of clutch, so just can forbid carrying out self-acting clutch control, can only carry out manual clutch's control; If there is not let slip the clutch, so just automatically carry out self-acting clutch control.
That is to say, when chaufeur comes control clutch by the method for oneself wishing, needn't can carry out according to the clutch operating flow process of the usual custom of people as the another kind of unused operation different the change-over swith operation with clutch operating.
