Specific embodiment
The embodiment of the present invention is described below in detail, examples of the embodiments are shown in the accompanying drawings, wherein from beginning to end
Same or similar label indicates same or similar parameter or element with the same or similar functions.Below with reference to attached
The embodiment of figure description is exemplary, and for explaining only the invention, and is not construed as limiting the claims.
A kind of start auxiliary control method provided by the invention and system, by adjusting clutch sensor position make from
Clutch is switched in the light stepping on clutch pedal of driver, i.e., sends clutch switch signal to electronic control unit and allow electronic control
Unit (ECU) enters state of a control in advance, and therefore, the clutch switch signal time provided is longer, can be in advance to starting to walk
Journey makes correct reaction.
Technical solution and technical effect in order to better understand the present invention, below with reference to flow diagram to specific
Embodiment is described in detail.
As shown in Figure 1, for according to a kind of flow chart of start auxiliary control method of the embodiment of the present invention, the method for the present invention packet
Include following steps:
Step S01 pre-adjusts the position of clutch switch, so that clutch switch is located at calibration position in clutch pedal
When setting to electronic control unit send clutch switch signal, it is described calibration position be clutch pedal maximum displacement 5% to
30%
In the present embodiment, by pre-adjusting the position of clutch switch, so that working as driver's stepping on clutch pedal extremely
When 5% to 30% position, the circuit of clutch switch is switched on signal, can provide signal in advance, allows electronic control unit
(ECU) enter state of a control in advance, therefore, the clutch switch signal time provided is longer, can be more in advance to starting-up process
Correct reaction is made, the realization that the present invention is simple and efficient is displaced to react as soon as possible with smaller clutch pedal
The movement of driver's stepping on clutch pedal, and without using the expensive equipment such as linear clutch position sensor.
As shown in Fig. 2, being the correspondence diagram of clutch switch signal and clutch switch position.With the calibration
Position is illustrated for being the 10% of clutch pedal maximum displacement, from figure this it appears that when calibration position is clutch
Device pedal maximum displacement 10% when with the calibration position of the prior art be 90% comparing for clutch pedal maximum displacement, give
The clutch engagement signal time out is longer, can correctly react driving shift process.And the prior art can only react loose clutch
Process, and the process of entire stepping on clutch and loose clutch cannot be reacted.
Step S02 gives target idling speed when vehicle stops and electronic control unit receives clutch switch signal
Increase by the first increment, 50 turns≤first increment≤300 turn.
In the present embodiment, whether stopped by vehicle and whether receive clutch switch signal to judge vehicle be
It is no to enter starting stage, the Rule of judgment set in this way and the prior art by more many condition to determine whether having entered step
Section is more simple and efficient, and identify it is accurate, for example, 1, speed is less than speed limit value V0, wherein 0km/h≤V0≤10km/h；2, it sends out
Motivation revolving speed is greater than engine speed limit value N0, wherein 0rpm≤N0≤3000rpm；3, transmission gear signal T0, wherein
T0 indicates transmission gear in shelves；4, efp opening amount signal is P0, and wherein P0 indicates that gas pedal is not operated；5,
Brake signal is B0, and wherein B0 indicates that brake pedal is not operated.
Specifically, the clutch switch exports high level when clutch pedal position is more than calibration position；It is described from
Clutch switch exports low level when clutch pedal position is less than calibration position, for example, the clutch switch is in clutch
Device pedal position exports 12V voltage when being more than calibration position, and the clutch switch is less than calibration in clutch pedal position
0V voltage is exported when position.
In the present embodiment, if automobile enters the starting stage, to target idling speed increase the first increment, 50 turns≤
First increment≤300 turn.Thus can to avoid small displacement engine in the starting stage since target idling speed is lower
The problem for causing starting difficult.
Specifically, after increasing by the first increment to target idling speed, according to revised target idling speed to starting
Machine carries out idle speed control, for example, enter the PID closed loop revolving speed control that starting operating condition executes starting revolving speed, it is reasonable by pid parameter
Calibration control throttle opening remains engine speed near the idling speed of starting operating condition.
Start auxiliary control method provided by the invention, due to pre-adjusting the position of clutch switch, so that clutch
Switch sends clutch switch signal to electronic control unit when clutch pedal is located at calibration position, and the calibration position is
The 5% to 30% of clutch pedal maximum displacement, this with compared at traditional 90%, when driver has just started stepping on clutch pedal
When to 5% to 30% position, the circuit of clutch switch is switched on signal, can provide signal in advance, allows electronic control unit
(ECU) enter state of a control in advance, therefore, the clutch switch signal time provided is longer, can do in advance to starting-up process
Correctly reaction out thus efficiently solves the problems, such as that small displacement engine starting is difficult.
As shown in figure 3, for according to second of flow chart of start auxiliary control method of the embodiment of the present invention, in the present embodiment
In, the method also includes:
Step S31, after increasing by the first increment to target idling speed, when accelerator open degree is greater than calibration aperture, then
Target idling speed is set to be restored to normal target idling speed.
In the present embodiment, when accelerator open degree is greater than calibration aperture, then show that driver has intervened starting operating condition, start to walk
Auxiliary control logic can exit.
As shown in figure 4, for according to the third flow chart of start auxiliary control method of the embodiment of the present invention, in the present embodiment
In, the method also includes:
Step S41, when vehicle stops and electronic control unit receives clutch switch signal, electronic control unit
Judge whether to receive electronic-controlled power steering switching signal.
In the present embodiment, due to consideration that vehicle carries out the bigger torque of this needs of starting to walk when beating steering wheel, therefore,
Electronic-controlled power steering switching signal is also further acquired, may determine that whether current be to play steering wheel starting by the signal, so as to
In for beat steering wheel start to walk optimize.
Step S42, if it is, increase by the second increment to target idling speed, 150 turns≤second increment≤400
Turn, such as 150 turns, 200 turns, 250 turns, 300 turns, 350 turns, 400 turns etc..Preferably, the second increment is 200 turns.
Step S43, if it is not, then increase by the first increment to target idling speed, 50 turns≤first increment≤300
Turn, such as 50 turns, 100 turns, 150 turns, 200 turns, 250 turns, 300 turns etc., it is preferable that the first increment is 100 turns.Wherein, second
Increment is greater than the first increment.
The oil-filled self-adaptation control method and system of wet clutch provided by the invention, when vehicle stopping and electronics control
When unit processed receives clutch switch signal, electronic control unit judges whether to receive electronic-controlled power steering switching signal, due to
Vehicle spins to when starting reversing or outbound, and required torque is bigger, can if be not modified to target idling speed
There is the difficult problem of starting, then the present invention judges idle to target accordingly by further acquiring electronic-controlled power steering switching signal
Fast revolving speed increases the first increment or the second increment, and this addresses the problem vehicles to spin to being easy to appear when starting reversing or outbound
Start to walk difficult problem.
