The above description is only an overview of the technical scheme of the present invention, in order to better understand the technical means of the present invention,
And it can be implemented in accordance with the contents of the specification, and in order to allow above and other objects, features and advantages of the invention can
It is clearer and more comprehensible, it is special below to lift preferred embodiment, and cooperate attached drawing, detailed description are as follows.
Detailed description of the invention
Fig. 1 show the schematic diagram of manual transmission clutch control device of the present invention.
Fig. 2 show the flow diagram of manual transmission clutch control method of the present invention.
Specific embodiment
It is of the invention to reach the technical means and efficacy that predetermined goal of the invention is taken further to illustrate, below in conjunction with
Attached drawing and preferred embodiment, the present invention is described in detail as follows.
Fig. 1 show the schematic diagram of manual transmission clutch control device of the present invention.As shown in Figure 1, the present invention is manual
Transmission clutch control device includes clutch slave cylinder pressure sensor at the clutch slave cylinder, Engine ECU, shift
Bar position sensor, accelerator open degree sensor and engine speed sensor.These sensors connect with Engine ECU signal
It connects.
Wherein, shift lever position sensor, accelerator open degree sensor and engine speed sensor are respectively used to detect
Position, accelerator open degree and the engine speed of gear lever.Clutch slave cylinder pressure sensor is in gaging clutch wheel cylinder
Pressure, and clutch slave cylinder pressure signal is transmitted to Engine ECU.The bonding state of clutch is stored in Engine ECU
The linear relationship (linear relationship is obtained through test of many times test) of (binding site) and clutch slave cylinder pressure, in this way,
Reflect the bonding state of clutch by the wheel cylinder pressure of clutch.After Engine ECU is connected to clutch slave cylinder pressure signal,
(it can refer to the matching of current shift, clutch association rate, accelerator open degree, engine speed of vehicle etc. according to actual condition
Situation) control the control parameter of engine.
Specifically, when vehicle is in 1 grade of original place or reverses gear, Engine ECU is sent out after obtaining clutch binding signal
After motivation ECU detects that the wheel cylinder pressure of clutch starts variation, the rate that detection clutch combines, if clutch combination is slower
(binding time is greater than the set value, usually several seconds of zero point), Engine ECU can turn according to normal operating conditions engine
Speed；(binding time is less than setting value) is quickly combined when Engine ECU detects clutch and throttle is not accelerated, to guarantee
Normal starting, controlling engine promotion engine speed 100RPM at this time, (lifting values of the revolving speed may be other numbers
Value), to prevent from stopping working because of revolving speed towing astern；When clutch have been combined and throttle do not carry out accelerate or engine speed acceleration
When being unsatisfactory for requiring (i.e. Throttle Opening Control is insufficient), Engine ECU can change according to the bonding state and engine speed of clutch
Rate carries out oil spout ignition control.
(2-5 grades or 6 grades) when the vehicle is running, during adding and subtracting shelves, it is contemplated that the comfort for driving shift, from
When clutch is totally released, current rotating speed of engine is maintained in Engine ECU meeting short time (usually several hundred milliseconds), to avoid
Bring revolving speed towing astern and impact, preferably promote driving performance when clutch recombines.
In addition, Engine ECU has self-learning function, the data in relation to driving habit can be acquired in driving procedure,
It forms self-learning function data to store to Engine ECU, and regularly updates, in this way, can be according to driving habit when driving
Control parameters of engine is finely adjusted, also, self-learning function is also convenient for when replacing driver, according to different drivers'
Driving style adjusts engine parameter.
As shown in Fig. 2, manual transmission clutch control method of the invention includes the following steps:
Step S1: acquiring the position of gear lever, and the current shift of vehicle is judged according to the position of gear lever；
Step S2: acquiring the wheel cylinder pressure signal of clutch, judges clutch according to the wheel cylinder pressure signal of clutch
Association rate；
Step S3: acquisition accelerator open degree and engine speed；
Step S4: according in the current shift of vehicle, the association rate of clutch, accelerator open degree and engine speed at least
The control parameter of two match condition adjustment engines.
In step s 4, when vehicle is in 1 grade of original place or reverses gear, if the association rate of clutch is less than setting value (i.e.
The binding time of clutch is greater than the set value, usually several seconds of zero point), Engine ECU can be sent out according to normal operating conditions
Motivation revolving speed；
If the association rate of clutch is less than setting value and throttle is not accelerated, to guarantee normal starting, can control at this time
Engine processed promotes engine speed 100RPM (lifting values of the revolving speed may be other numerical value), to prevent because of revolving speed towing astern
And stop working；
If clutch has been combined and throttle does not carry out accelerating or engine speed acceleration is unsatisfactory for requiring (i.e. throttle control
System is insufficient) when, Engine ECU can carry out oil spout point fire control according to the bonding state of clutch and engine speed rate of change
System.
(2-5 grades or 6 grades) when the vehicle is running, during adding and subtracting shelves, it is contemplated that the comfort for driving shift, from
When clutch is totally released, current rotating speed of engine is maintained in Engine ECU meeting short time (usually several hundred milliseconds), to avoid
Bring revolving speed towing astern and impact, preferably promote driving performance when clutch recombines.
In conclusion the present invention by the way that clutch slave cylinder pressure sensor is arranged at clutch slave cylinder, is obtained by test
The bonding state of clutch and the linear relationship of clutch slave cylinder pressure are obtained, and the linear relationship is stored to Engine ECU,
Allow Engine ECU after being connected to clutch slave cylinder pressure signal, the parameter setting of engine controlled according to actual condition,
The gentle start and/or shift for realizing vehicle avoid the occurrence of towering vehicle and stop working.
The above described is only a preferred embodiment of the present invention, be not intended to limit the present invention in any form, though
So the present invention has been disclosed as a preferred embodiment, and however, it is not intended to limit the invention, any technology people for being familiar with this profession
Member, without departing from the scope of the present invention, when the technology contents using the disclosure above make a little change or modification
It is right according to the technical essence of the invention for the equivalent embodiment of equivalent variations, but without departing from the technical solutions of the present invention
Any simple modification, equivalent change and modification made by above embodiments, all of which are still within the scope of the technical scheme of the invention.
