Any and all combinations of the listed item of pass.
Known, ECU is rotated with the motor of identical control model control gear shifting actuating mechanism, drives gear shifting actuating mechanism
In associated mechanical or plastic components complete gear shifting action.
And around gear shifting actuating mechanism and its variation of internal temperature, it will lead to above-mentioned mechanical or plastic components and lubrication
The performance of grease changes.To which the frictional force in shift process can also change accordingly.In this way, shift execution machine
Under the driving of identical voltage, the speed of connecting rod is different the motor of structure.To, lead to shift time variation with temperature and
Variation, it is difficult to realize stable shift time.
Fig. 1 be in the prior art the motor input voltage of gear shifting actuating mechanism, connecting rod movement speed and connecting rod motion bit
Change curve schematic diagram between setting.Wherein, the X-axis (horizontal axis) in two figures indicates the movement position of connecting rod, Y-axis (longitudinal axis)
Indicate the input voltage of motor and the movement speed of connecting rod.
As shown in Figure 1, the connecting rod of gear shifting actuating mechanism is driven by a motor to drive the rocker arm of gearbox to swing and realize shift
Process, following three Duan Hangcheng can be divided into:
A: initial time, it is also maximum voltage VOL (max) that it is steady state value that ECU, which controls the voltage inputted to motor,.Motor
Corresponding revolving speed is maximum value, and connecting rod reaches reduction of speed node location d1 point with maximum speed Speed (max) uniform motion.
The first segment stroke is at the uniform velocity stroke, i.e. the distance between 0 to d1 point in Fig. 1.This section of stroke experience time be
At the uniform velocity journey time is denoted as t1.
B: when link motion to d1 point, the input voltage for reducing motor is controlled by PI.With the gradually drop of input voltage
Low, the revolving speed of motor declines therewith.The speed of connecting rod is also gradually decrease to minimum by peak Speed (max) accordingly
Speed (min), until link motion extremely power-off node location d2 point.
The second segment stroke is reduction of speed stroke, i.e. d1 point is the distance between to d2 point in Fig. 1.The time of this section of stroke experience
For reduction of speed journey time, it is denoted as t2.
C: when the movement speed of connecting rod is down to Speed (min), voltage input is cut off.Connecting rod under effect of inertia, continue to
Preceding mobile a distance (error distance) reaches final goal position dD.
The third section stroke is collision avoided, i.e. d2 point is the distance between to dD point in Fig. 1.The time of this section of stroke experience
For the collision avoided time, it is denoted as t3.Then shift time is t1+t2+t3.
It should be noted that connecting rod described herein is moved to a certain position, can with any one point on connecting rod or
Person position is as a reference point or benchmark determines.For example, the end that can be used to be connected with the rocker arm of gearbox with connecting rod
Portion is as moving reference point or benchmark.Alternatively, since the rocker arm of connecting rod and gearbox is generally rigidly connected.Therefore, it can also incite somebody to action
Rocker arm is as the reference point or benchmark.
Illustrated in Figure 1 is temperature inside gear shifting actuating mechanism when being a certain particular value (such as a certain stationary temperature
Value T1), the change curve between motor input voltage, connecting rod movement speed and the movement position of connecting rod.Once execution machine of shifting gears
When the temperature of the inside of structure changes, then between motor input voltage, the movement speed of connecting rod and the movement position of connecting rod,
It can change therewith.
It is lower than above-mentioned particular value (T1) with temperature (T2), i.e. temperature is illustrated for being lower.
As shown in Fig. 2, gear shifting actuating mechanism internal part and peripheral lubrication are oil since temperature reduces (T2 < T1)
It can vary with temperature, the mobile frictional resistance that will lead to connecting rod becomes larger.Cause under same motor input voltage VOL (max),
The initial motion speed of connecting rod becomes smaller.
Anticipate as shown in Figure 2, in the identical situation of initial input voltage VOL (max) of motor, connecting rod it is initial
Speed is by the Speed1 (min) at a temperature of T1, the Speed2 (min) being reduced at a temperature of T2.Then connecting rod reaches reduction of speed node location
At the uniform velocity journey time t1 needed for d1 point is elongated.
In reduction of speed stroke, since the moving resistance of connecting rod increases, thus as connecting rod reduction of speed to Speed (min), not yet
Reach power-off node location d2 point.Another position d3 point anticipated as shown in Figure 2, the d3 point are located at before d2.In this way,
Error distance, that is, collision avoided lengthens.In addition temperature reduces, and link motion frictional resistance increases, to reach shift mesh
The collision avoided time needed for cursor position dD, t3 was also elongated.
In this way, shift time can extend when ambient temperature reduces and gear shifting actuating mechanism internal temperature is caused to decline.Together
Sample, if ambient temperature increases and gear shifting actuating mechanism internal temperature is caused to increase, shift time can shorten.
In view of this, the embodiment of the invention provides a kind of control method of gear shifting actuating mechanism, device and shift controls
System.The embodiment of the present invention passes through the temperature inside detection gear shifting actuating mechanism, and by temperature feedback to ECU.ECU is according to detection
The temperature arrived, adjustment is input to the driving parameter of the motor of gear shifting actuating mechanism in real time, to realize stabilization at different temperature
Or consistent shift time.
In the present invention, gear shifting actuating mechanism may include the known embodiments that arbitrarily can be realized electric gear change function,
This is not limited by the present invention.
In a specific implement scene, gear shifting actuating mechanism can use notification number to be provided by CN106838303B
Known embodiments.All the elements of the known embodiments disclose in the present invention by reference, and therefore not to repeat here.
As shown in fig. 7, in one embodiment, the control method may include steps of:
Step S101: the working temperature inside the gear shifting actuating mechanism is obtained.
The temperature of the enclosure interior of working temperature, in particular to gear shifting actuating mechanism inside gear shifting actuating mechanism.Temperature
Acquisition modes can be to detect the intracorporal temperature of shell by using the temperature detecting element connecting with ECU signal, then will test
Temperature value be sent to ECU.
Temperature detecting element can use any appropriate existing construction, and not according to specific structure and temperature-measurement principle
Together, it adaptively designs or adjusts it and position is set, the embodiment of the present invention is not construed as limiting this.
For example, temperature detecting element can be temperature sensor or thermocouple etc., can be set in shift execution machine
In the shell of structure.Alternatively, the shell in gear shifting actuating mechanism can also can be set with infrared temperature measurement apparatus in temperature detecting element
Outside.
Step S102: being based on the working temperature, concentrates in preset data and obtains match parameter, and the match parameter includes
There is driving voltage, the driving voltage and the working temperature are in inverse correlation relationship.
To realize that stable or consistent shift time can be adjusted the input voltage of motor for temperature change, with
The connecting rod for making gear shifting actuating mechanism at different temperature, realizes identical movement.
It continues from the preceding paragraph description, temperature reduces, and the moving resistance of connecting rod increases.Then motor drives under identical input voltage
The mobile speed of dynamic connecting rod will reduce, and then shift time is caused to extend.Conversely, temperature increases, shift time shortens.
Therefore, in order to make connecting rod under different working temperatures, speed that is identical or connecting is maintained or is kept, needs to be directed to
The difference of working temperature, the adjusting of suitability are input to the driving voltage of motor.
Specifically, when the temperature decreases, the moving resistance of connecting rod increases, the driving voltage for being input to motor can be improved.And
When the temperature increases, the moving resistance of connecting rod reduces, and can reduce the driving voltage for being input to motor.
It is, driving voltage is reduced with the raising of working temperature, increase with the decline of working temperature.
Preset data collection can wrap containing the corresponding relationship between multiple groups temperature range and driving voltage.By will test
Working temperature as known quantity, compared in preset data concentration, determine the target temperature section that working temperature is fallen into,
To obtain driving voltage corresponding with the target temperature section.Wherein, target temperature section is in multiple temperature ranges
One.
The expression-form of preset data collection can be { [T1, T2] ‖ VOL } as a result,.Wherein, T1, T2 are the two of temperature range
A endpoint value.Each temperature range corresponds to a driving voltage VOL.When working temperature fall into some temperature ranges [T1,
T2] in the range of (i.e. target temperature section) when, can be obtained driving voltage VOL corresponding with the temperature range.
Step S103: the match parameter is supplied to the motor.
After obtaining the match parameter comprising driving voltage based on temperature, motor can be sent it to.Motor is in the matching
It is run under the driving of parameter.
Since the driving voltage and working temperature for including in match parameter are in inverse correlation relationship.Therefore, this is input to motor
Driving voltage, the variation for leading to the moving resistance of connecting rod because of temperature change can be compensated for.In this way, connecting rod is in different working temperatures
Same or similar movement can be achieved, down so as to keep the stabilization of shift time.
In the present embodiment, driving voltage may include first voltage and the second voltage less than first voltage, and first
Voltage and second voltage are respectively equivalent to maximum voltage VOL (max) and minimum voltage VOL (min) described above.
Then correspondingly, in the step of obtaining match parameter, match parameter can also include first stroke time and second
Journey time.Wherein, the first stroke time be first voltage load time, the second stroke time be motor input voltage by
Time needed for first voltage is down to second voltage.
Corresponding, preset data collection can further include multiple groups temperature range and driving voltage, first stroke
Corresponding relationship between time, second stroke time.By the working temperature that will test as known quantity, in the preset data
Concentration compares, and determines the target temperature section that working temperature is fallen into, to obtain corresponding with the target temperature section
Driving voltage, first stroke time, second stroke time are as match parameter.
The expression-form of preset data collection can be further refined as { [T1, T2] ‖ VOL, t1, t2 } as a result,.Wherein, it drives
Voltage VOL further may include first voltage VOL1 and second voltage VOL2, t1 are the first stroke time, when t2 is second stroke
Between.When working temperature is fallen into the range of some temperature range [T1, T2], can be obtained corresponding with the temperature range
Driving voltage VOL, first stroke time t1 and second stroke time t2.
Preset data collection can be by testing in advance or testing acquisition.Specifically, can workable temperature by gear shifting actuating mechanism
Degree range is divided into several temperature ranges.Then, then respectively measure under each temperature range, connecting rod reaches identical first speed
The load of degree, identical second speed institute corresponding first voltage VOL1, second voltage VOL2 and first voltage VOL1
When m- first stroke time t1, motor input voltage when being down to the second stroke of second voltage VOL2 by first voltage VOL1
Between t2.To obtain preset data collection.
For example, gear shifting actuating mechanism can workable temperature range be -40 DEG C~140 DEG C, be classified as 18 humidity provinces
Between, 18 temperature ranges be respectively [- 40 DEG C~-30 DEG C], [- 29 DEG C~-20 DEG C], [- 19 DEG C~-10 DEG C] ... [131 DEG C~
140℃].It is measured under each temperature range respectively, connecting rod reaches identical First Speed, identical second speed is respectively corresponded
Motor first voltage VOL1, second voltage VOL2 and first stroke load time-, t1 time of first voltage VOL1, horse
The input voltage reached is down to the second stroke time t2 of second voltage VOL2 by first voltage VOL1.To obtain preset data
Collection.
Within the first stroke time, the input voltage of motor is first voltage, and connecting rod is actuated to First Speed and at the uniform velocity transports
It goes to first node position.Within the second stroke time, the input voltage of motor is by first voltage gradually near second voltage, then
The speed of connecting rod is down to second speed by First Speed accordingly, and connecting rod is run to second node position.
First Speed and second speed are respectively equivalent to maximum speed Spped (max) and minimum speed described above
Spped(min)；First node position and second node position are respectively equivalent to reduction of speed node location d1 point described above and break
Electrical nodes position d2 point.
In the present embodiment, the input voltage of motor is down to second voltage by first voltage, can be such as Fig. 1 and Fig. 3 institute
The linear decline of signal is also possible to the decline of other forms.Such as index decreased, logarithm decline etc., the embodiment of the present invention pair
This is not construed as limiting.
When the input voltage of motor is down to second voltage, i.e., when connecting rod reaches second node position, the input voltage of motor
It is cut off.Connecting rod has continued to move to the third trip time under effect of inertia, until target shift position stops.
Likewise, making connecting rod maintain identical movement speed, first voltage and the second electricity in order under different working temperatures
Pressure is in inverse correlation relationship with working temperature.
As a result, by inputting first voltage to motor come suitability based on working temperature, then in working temperature difference,
It can make the motor identical First Speed that drive link obtains under the action of different first voltages.
In one embodiment, first node position is also identical.In this way, under different working temperatures, when first stroke
Between can keep stable or constant.Since connecting rod at the uniform velocity moves in first stroke.Therefore, by determining that first node position makes
The first stroke time keeps stable or constant under different working temperatures, can facilitate and carry out being segmented accurate control to shift time.
Since under different working temperatures, the first stroke time is identical.Therefore, if can guarantee the second stroke time with
The sum of third trip time be in different temperatures it is stable or consistent, the stability or one of shift time can be realized
Cause property.
In one embodiment, target shift position is reached unanimity.It is specifically as follows, target shift position can be predetermined
Fluctuation in range.As shown in Figures 3 to 6, target shift position is dD point, can have fault-tolerance distance d0.When connecting rod is mobile
When in the range of to [dD-d0, dD+d0], i.e., it is believed that connecting rod reaches target shift position.
Since first stroke is identical under different working temperatures, then the sum of second stroke and third trip are constant
's.In order to make the sum of second stroke time and third trip time keep stable or consistent in different temperatures, at one
In embodiment, second speed is identical under different working temperatures, and second stroke time and working temperature are positively correlated pass
System.
In one case, when working temperature increases, the second stroke time being matched to is larger.Due to First Speed and
Second speed be all it is determining, then second stroke extends, and third trip then shortens accordingly.In addition working temperature raising is led
The decline of connecting rod moving resistance is caused, so that the third trip time will shorten.The second stroke time is larger as a result, and when third trip
Between it is smaller, it can be achieved that the stability or consistency of the sum of second stroke time and third trip time in different temperatures.
In one case, when working temperature declines, the second stroke time being matched to is smaller.So second stroke contracts
It is short, and third trip then extends accordingly.In addition working temperature decline causes connecting rod moving resistance to increase, thus when third trip
Between will increase.The second stroke time is smaller as a result, and the third trip time is larger, the equally achievable second stroke time and the
Stability or consistency of the sum of the triple-travel time in different temperatures.
Specifically, as shown in Figure 3 and Figure 4, temperature T1 > T2.Then according to above scheme, matched second row at a temperature of T1
Journey time t21 longer, and matched second stroke time t22 is shorter at a temperature of T2.
Since the First Speed at two temperature is identical with second speed.So correspondingly, what T1 temperature lower link was run
Second stroke is longer, and the second stroke of T2 temperature lower link operation is shorter.D21 is embodied at a distance from d1, is greater than d22
At a distance from d1.
Collision avoided, that is, third trip of T1 temperature lower link is shorter as a result, the collision avoided of T2 temperature lower link i.e.
Triple-travel is longer.To, the third trip time t31 of T1 temperature lower link is shorter, and when the third trip of T2 temperature lower link
Between t32 longer.
The second stroke time t21 longer of T1 temperature lower link, the third trip time, t31 was shorter.And T2 temperature lower link
Second stroke time t22 it is shorter, third trip time t32 longer.Then connecting rod is at a temperature of two different, when second stroke
Between with the sum of time third trip time, it can be achieved that stable or consistent.
In this embodiment, within the second stroke time, the variation tendency that first voltage is down to second voltage can be phase
With.It can specifically show as, as shown in Figure 3, the slope of voltage change curve corresponding to T1 temperature and T2 temperature is identical
's.In this way, velocity variations trend (i.e. acceleration) is also identical when connecting rod is driven by a motor.In this way, due to different operating conditions
At a temperature of, First Speed and second speed be all it is identical, then the second stroke time is longer, and the distance of second stroke is also longer.
In another embodiment, second node position and second stroke time are identical respectively under different working temperatures,
Second speed and working temperature are in inverse correlation relationship.
Second node position and second stroke time are distinguished identical specifically, second node position under different working temperatures
Under different working temperatures be it is identical, the second stroke time is also identical under different working temperatures.
Due to second node position be under different working temperatures it is identical, then second stroke is under different working temperatures
It is i.e. identical.In addition first stroke is identical under different working temperatures, then third trip is also constant.Simultaneously as second
Journey time is constant under different working temperatures.Therefore, as long as can guarantee that the third trip time is in different temperatures
It is stable or consistent, the stability or consistency of shift time can be realized.
It continues from the preceding paragraph description, due to the initial velocity that second speed is third trip.So, the feelings constant in third trip
Under condition, as long as the second speed made and working temperature are in inverse correlation relationship, that is, it may make the third trip time in different operating condition temperature
It is consistent under degree.
Further, since second stroke and First Speed do not change with working temperature.So, second speed to be made is in operating condition
At a temperature of it is different, only need to reach above-mentioned purpose by control first voltage to the reduction speed of second voltage.
Specifically, according to acceleration displacement principle, in the case where second stroke and constant First Speed, by
In two journey times, by the decrease speed that first voltage is down to second voltage be set as with working temperature correlation, i.e.,
Second speed can be achieved and working temperature is in inverse correlation relationship.The decrease speed that first voltage is down to second voltage specifically can be with table
It is now the slope of voltage change curve shown in fig. 5.
The input voltage of motor influences and is associated with the movement speed of connecting rod, and the variation of the movement speed of practical upper connecting rod becomes
Gesture follows the variation tendency of the input voltage of motor always.Therefore, the input voltage of motor is down to the second electricity by first voltage
The decrease speed of pressure is directly linked translational acceleration of the connecting rod within the second stroke time.
Based on this, when working temperature increases, the decrease speed that first voltage is down to second voltage is improved.It is so corresponding
, when connecting rod is driven by a motor, translational acceleration increases.So, in the case where second stroke and constant First Speed, second
Speed will reduce.
Likewise, the decrease speed that first voltage is down to second voltage reduces when working temperature decline.It is so corresponding
, when connecting rod is driven by a motor, translational acceleration reduces therewith.So, in the case where second stroke and constant First Speed,
Second speed will increase.
Specifically, as shown in Figure 5 and Figure 6, temperature T1 > T2.Then according to above scheme, at a temperature of T1 under matched voltage
Reduction of speed degree is larger, and matched voltage decrease speed is smaller at a temperature of T2.
Since second stroke and First Speed are constant identical.So correspondingly, T1 temperature lower link is run to second node
