The method at least includes steps S210 to S220 before S110 shown in fig. 1, and is described in detail as follows:
s210: and detecting whether the electromagnetic valve of the clutch has a flushing fault at the current moment.

If the corresponding scouring fault is not detected, the common vehicle cannot scour the clutch solenoid valve, so that no accumulated debris can be ensured in the clutch solenoid valve, and the normal operation of the clutch solenoid valve can be influenced even if the corresponding scouring fault is not detected.
Therefore, the present application provides another method for flushing a clutch solenoid valve, and referring to fig. 3 in particular, fig. 3 is a flowchart of another method for flushing a clutch solenoid valve, which is proposed based on the embodiment shown in fig. 2. The method further includes at least S310, which is described in detail below:
s310: and if the scouring fault of the clutch electromagnetic valve at the current moment is not detected, stopping acquiring the whole vehicle working condition and the running parameters of the vehicle at the current moment, and scouring the clutch electromagnetic valve according to a preset periodic scouring mode.
The preset periodic flushing mode is a mode for periodically flushing the clutch electromagnetic valve under the condition that a corresponding flushing fault of the clutch electromagnetic valve is not detected, and comprises parameters such as a flushing direction, a flushing force, a flushing time and a flushing period, wherein the parameters are preset in a vehicle before leaving a factory.
If the washout fault of the clutch electromagnetic valve at the current moment is not detected, the whole vehicle working condition and the running parameters of the vehicle do not need to be recorded and acquired, and the clutch electromagnetic valve can be periodically washed out directly according to a preset periodic washout mode.
In some embodiments, if the washout fault of the clutch electromagnetic valve at the current time is not detected, the whole vehicle working condition and the operation parameters of the vehicle at the current time also need to be acquired, the working state of the vehicle at the current time is determined according to the whole vehicle working condition so as to match the periodic washout mode at the current time, and the operation parameters are further included to determine whether the clutch electromagnetic valve can be washed in the periodic washout mode at the current time. Illustratively, if the electromagnetic valve of the clutch does not have a flush fault at the current moment, the whole vehicle working condition and the running parameters of the vehicle at the current moment are recorded and acquired. If the working condition of the whole vehicle indicates that the gear of the vehicle is placed in a neutral gear and the engine is closed, the corresponding flushing mode is an up-down flushing mode with large periodicity, and the flushing period is 2 minutes; and if the operation parameters meet the preset operation parameters, the clutch electromagnetic valve is subjected to large-amplitude up-and-down flushing every 2 minutes.
The embodiment further illustrates that when the washout fault of the clutch solenoid valve is not detected, the clutch solenoid valve is washed according to the preset periodic washing mode to ensure that no accumulated debris exists in the clutch solenoid valve, and even under the condition that the washout fault is not detected, the clutch solenoid valve can be periodically washed to reduce the frequency of the clutch solenoid valve that the clutch solenoid valve is stuck due to the accumulated debris, so that the normal operation of the clutch solenoid valve is ensured.
The existing flushing scheme of the electromagnetic valve of the clutch does not cover all vehicle conditions, and causes the conditions of low flushing frequency, poor NVH (Noise, vibration and Harshness) performance, general flushing effect and the like in one driving cycle.
Therefore, the present application provides another method for flushing a clutch solenoid valve, so as to determine different flushing modes according to different vehicle conditions, so as to perform a flushing operation of the corresponding flushing mode on the clutch solenoid valve, specifically referring to fig. 4, where fig. 4 is a flowchart of another method for flushing a clutch solenoid valve, which is proposed based on the embodiment shown in fig. 1. The method further includes at least S410 to S430 in S120 shown in fig. 1, and is described in detail below:
s410: and if the working condition of the whole vehicle indicates that the gear of the vehicle is placed in a neutral gear and the engine is closed, determining that the flushing mode of the electromagnetic valve of the clutch at the current moment is a first flushing mode.
The flush in the first flush mode has the greatest magnitude and the direction of the flush is up and down.
For example, if the vehicle is in neutral and the engine is off, and the clutch is not engaged and there is no speed differential, the solenoid valve of the clutch is flushed up and down with a PWM (Pulse Width Modulation) current as shown in fig. 5, with a current value in the range of [0, 800] ma, while the electronic pump speed is adjusted to a predetermined electronic pump speed, such as 2000rpm as shown in fig. 5. Fig. 5 is a schematic diagram illustrating a variation process of a current value of a PWM current.
S420: and if the working condition of the whole vehicle indicates that the vehicle is in a pure electric or range-extending mode, or the gear of the vehicle is placed in a neutral gear and the engine is started, determining that the flushing mode of the electromagnetic valve of the clutch at the current moment is a second flushing mode.
The second flush mode is a flush mode with a smaller flush magnitude and a downward flush direction.
Illustratively, if the vehicle operating conditions indicate that the vehicle is in a pure electric or range extending mode, when the clutch is not engaged but has a speed difference, the clutch solenoid is flushed down using PWM currents as shown in fig. 6, and fig. 6 is a schematic diagram of the variation process of the current values of another PWM current, in which the clutch solenoid is flushed down with a small amplitude in PWM form [0,0.6bar ] ma current.
S430: and if the working condition of the whole vehicle represents that the vehicle is in a direct-drive mode, determining that the flushing mode of the electromagnetic valve of the clutch at the current moment is a third flushing mode.
The second flush mode is a flush mode with a smaller flush magnitude and an upward flush direction.
Exemplarily, if the vehicle is in a direct-drive 1 gear or a direct-drive 2 gear, only a clutch disengagement failure fault can trigger a flushing mode in a direct-drive mode, at this time, the clutch is combined with no speed difference, the clutch electromagnetic valve is flushed upwards by adopting the PWM current shown in fig. 7, fig. 7 is a schematic diagram of a change process of a current value of another PWM current, wherein the clutch electromagnetic valve is flushed upwards in a small amplitude by a PWM form [ Lockup + offset,1500 ]; lockup + offset represents the minimum current value during the flush.
Different washing modes are determined according to different vehicle conditions of the whole vehicle in the embodiment to correspondingly wash the washing operation of the washing modes to the clutch solenoid valve, and the washing of different clamping stagnation conditions can be carried out on the clutch solenoid valve in multiple washing modes, so that the washing effect of the washing of the clutch solenoid valve is improved, and the clutch solenoid valve is better cleaned.
Under the working condition that the vehicle is placed in neutral and the engine is closed, how to accurately judge whether the running parameters of the vehicle at the current moment meet the preset running parameters is a technical problem to be solved urgently. To this end, the present application proposes another method for flushing a clutch solenoid valve in another exemplary embodiment, and referring to fig. 8, fig. 8 is a flowchart of another method for flushing a clutch solenoid valve proposed based on the embodiment shown in fig. 4. The operating parameters include clutch oil temperature and vehicle speed; if the working condition of the whole vehicle represents that the gear of the vehicle is placed in a neutral gear and the engine is closed; the method includes at least steps S810 to S820 in S120 shown in fig. 8, which are described in detail below:
s810: and detecting whether the clutch oil temperature at the current moment is greater than the preset clutch oil temperature and detecting whether the vehicle speed at the current moment is less than the preset vehicle speed.
Under the lower state of ambient temperature, if erode the clutch solenoid valve, cause clutch solenoid valve operation trouble easily, this embodiment judges whether ambient temperature satisfies the leading temperature condition that erodes the clutch solenoid valve at the present moment through detecting whether clutch oil temperature is greater than preset clutch oil temperature. For example, the clutch oil temperature must be above-10 ℃ to enable various flush modes of flushing operation of the clutch solenoid valve. The embodiment is a detection step performed under the premise that the vehicle gear is placed in the neutral position and the engine is closed under the condition that the working condition of the whole vehicle represents that the vehicle gear is in the neutral position, at the moment, the vehicle speed also becomes a detection object, and only if the vehicle speed at the current moment is smaller than the preset vehicle speed, the clutch electromagnetic valve can be flushed according to the first flushing mode.
S820: and if the detected clutch oil temperature at the current moment is greater than the preset clutch oil temperature and the detected vehicle speed at the current moment is less than the preset vehicle speed, determining that the operation parameters meet the preset operation parameters.
Illustratively, the preset clutch oil temperature is-10 ℃, the preset vehicle speed is 3km/h, if the clutch oil temperature at the current moment is greater than the preset clutch oil temperature, and the vehicle speed at the current moment is less than the preset vehicle speed, it is determined that the operation parameters meet the preset operation parameters, and the clutch electromagnetic valve can be flushed in a first flushing mode.
The embodiment further illustrates how to determine whether the operation parameters meet the preset operation parameters under the condition that the whole vehicle working condition represents that the vehicle gear is placed in the neutral gear and the engine is turned off, and accurately judges whether the operation parameters at the current moment under the whole vehicle working condition meet the preset operation parameters by respectively detecting whether the oil temperature of the clutch and the vehicle speed meet the corresponding preset threshold, so that the situation that the clutch electromagnetic valve is subjected to untimely flushing at the current moment to cause the operation fault of the clutch electromagnetic valve is avoided.
The external environment of the vehicle will determine to some extent whether the clutch solenoid valve can be flushed at the present time, i.e., whether the external environment allows flushing of the clutch solenoid valve is detected, and if the direct acquisition of the environmental parameters may have an inaccurate condition, a component or a device for acquiring the environmental parameters may need to be added.
Therefore, the present application provides another method for flushing a clutch solenoid valve, which determines whether the external environment allows to flush the clutch solenoid valve based on the current vehicle operating parameter, specifically referring to fig. 9, where fig. 9 is a flowchart of another method for flushing a clutch solenoid valve provided based on the embodiment shown in any one of fig. 1 to 4 and 8. The method further includes, in S120, S910 to S920, which are described in detail below:
s910: and detecting whether the clutch oil temperature is less than the preset clutch oil temperature.
S920: if the preset clutch oil temperature of the clutch oil Wen Xiaoyu is detected, the clutch electromagnetic valve is not flushed.
The temperature of the surrounding environment is too low, and the clutch electromagnetic valve is easy to freeze in the flushing process, so that the clutch electromagnetic valve cannot be flushed in any flushing mode under the condition that the temperature of the surrounding environment is too low, namely the external environment does not allow the clutch electromagnetic valve to be flushed.
For example, the preset clutch oil temperature is-10 ℃, if the clutch oil temperature at the current moment is-11 ℃, the temperature of the surrounding environment is too low, the external environment does not allow the clutch solenoid valve to be flushed, and the flushing operation of any flushing mode is not performed on the clutch solenoid valve.
In the embodiment, the clutch oil temperature is used as a monitoring object, and if the clutch oil Wen Xiaoyu is detected and the clutch oil temperature is preset, it indicates that the external environment does not allow the clutch electromagnetic valve to be flushed at the moment, and even if other flushing conditions are met, the clutch electromagnetic valve cannot be flushed.
