Background
During the clutch separation process driven by a hydraulic system, the following factors mainly have influence on clutch hysteresis: hysteresis in oil pressure and damping force when pushing the piston. For this, there are currently two solutions: 1. through observing the followability of actual pressure and target pressure, design compensation according to the gradient change of target pressure, or according to the pressure curve under the different temperatures, design open loop current compensation, and then reduce the error on the pressure, but even if actual pressure follows unanimously with the target pressure, when the clutch combines and separates under same pressure, its actual transmission moment of torsion still has the error, so this type of method can only indirectly alleviate the moment of torsion hysteresis. 2. The position of the clutch piston is monitored by arranging the position sensor, so that the combination and the separation of the clutch are controlled, but the position sensor is additionally arranged, so that the cost is increased, in addition, the resistance for pushing the piston in the service life of the clutch can be changed, so that the unpredictable change of the hysteresis is caused, and the method for fixedly mounting the sensor is difficult to accurately eliminate the hysteresis.

Detailed Description
In addition, the embodiments of the present invention and the features of the embodiments may be combined with each other without conflict.
The present invention will be described in detail below with reference to the accompanying drawings in conjunction with embodiments.
Fig. 1 is a schematic diagram illustrating a clutch hysteresis principle according to an embodiment of the present invention. As shown in fig. 1, when the driver shifts the shift lever from P to D in preparation for creep, as shown in fig. 1, the arrow pointing to the intersection of Pkp and T0 indicates the target clutch pressure Pkp and actual torque T0; when a driver starts or drives for a period of time and steps on the brake until the vehicle is stationary, the target pressure of the clutch is still Pkp, but the torque actually generated by the clutch is T0 'due to the existence of the torque lag of the clutch, and extra torque is actually applied to the engine when the request Pkp is caused because T0' > T0, so that the jitter and the idle fuel consumption are increased.
Fig. 2 is a flowchart of a method for controlling a clutch of a vehicle according to an embodiment of the present invention. As shown in fig. 2, the control method includes:
step S21, detecting a vehicle speed of the vehicle;
specifically, the vehicle speed may be detected using a vehicle speed sensor.
A step S22 of detecting a requested torque of the clutch and a torque of an engine of the vehicle when a vehicle speed of the vehicle drops to 0;
specifically, as described above, in order to solve the problem of the jerk caused by the clutch torque hysteresis after the driver brakes the vehicle to a standstill, the embodiment of the present invention starts to detect the torque requested by the clutch and the torque of the engine of the vehicle when the vehicle speed drops to 0.
And a step S23 of controlling negative pressure compensation of the target pressure of the clutch when an absolute value of a difference between the requested torque of the clutch and the torque of the engine is greater than a torque threshold value.
Specifically, as described above, the clutches are all at the target pressure during the running of the vehicle. On the basis of the absolute value of the difference between the torque request of the clutch and the torque of the engine, the embodiment of the invention judges the absolute value of the difference between the torque request of the clutch and the torque of the engine so as to perform negative pressure compensation on the target pressure of the current clutch when the absolute value is larger than the torque threshold value, namely, reduce the target pressure. The torque threshold value can be obtained by calibrating the hardware state of the clutch.
Specifically, the present invention provides a method for negative pressure compensation, as shown in fig. 3, the method comprising:
and step S31, controlling the value of the negative pressure compensation to increase from 0 to perform the negative pressure compensation on the target pressure of the clutch.
Specifically, when the negative pressure compensation is performed, the value of the negative pressure compensation is gradually increased from 0, i.e., from 0 to 5 to 10, for example, and the corresponding target pressure is gradually decreased due to the negative pressure compensation.
Step S32 of determining whether or not an absolute value of a difference between the requested torque of the clutch and the torque of the engine is equal to or less than the torque threshold value;
specifically, as the value of the pressure negative compensation gradually increases above, the embodiment of the invention provides a timing to determine whether to stop increasing it, that is, whether the absolute value of the difference between the requested torque of the clutch and the torque of the engine is equal to or less than the torque threshold value.
And a step S33 of controlling the value of the negative pressure compensation to stop increasing when the absolute value of the difference between the torque requested by the clutch and the torque of the engine is equal to or less than the torque threshold value.
Specifically, when the absolute value of the difference between the torque requested by the clutch and the torque of the engine is equal to or less than the torque threshold, indicating that the compensation at that time is sufficient, the increase in the value of the negative pressure compensation is stopped.
Fig. 4 is a flowchart of a method for controlling a clutch of a vehicle according to an embodiment of the present invention. As shown in fig. 4, after controlling the pressure negative compensation for the target pressure of the clutch, the method further includes:
step S41, detecting the brake pressure and/or the hand brake state;
specifically, after the vehicle stops, if the driver wants to start or creep the vehicle again, and if the pressure is compensated negatively, the normal running of the vehicle is affected. For this purpose, it is necessary to first determine whether the driver has an intention to start or creep the vehicle, that is, to detect the brake pressure or the handbrake state.
Step S42, judging whether the brake pressure is smaller than a pressure threshold value and/or whether the hand brake state is releasing;
and step S43, when the brake pressure is smaller than the pressure threshold value and/or the hand brake state is released, stopping performing pressure negative compensation on the target pressure of the clutch.
Specifically, when the brake pressure is smaller than the pressure threshold value and/or the hand brake state is released, the intention of the driver to start or creep the vehicle is indicated, and at the moment, the value of the negative pressure compensation is set to 0, namely, the negative pressure compensation on the target pressure of the clutch is stopped.
Fig. 5 is a flowchart illustrating a method for controlling a clutch of a vehicle according to an embodiment of the present invention. As shown in fig. 5, it is assumed that the driver starts normal driving by stepping on the accelerator at time t0, and then brakes for a time period t0-t1 until the vehicle stops; at time t1, since the hysteresis of the clutch is large, resulting in that the clutch fails to be completely disengaged when the clutch request torque is 0Nm, the torque of the engine is large, and at the time period t1-t2, the pressure hysteresis can be relieved to some extent and sufficient time is given to detect the torque difference; when the torque difference DeltaT 1 is larger than a torque threshold DeltaT 2 in a time period from T2 to T3, pressure negative compensation Pofs is given on the target pressure of the clutch, and Pofs is gradually increased until the torque difference is smaller than or equal to DeltaT 2; and entering a stage t3-t4, continuously giving Pofs, judging the brake pressure or the electronic hand brake state, and resetting Pofs when the brake pressure is lower than a pressure threshold and/or the electronic hand brake is released and the driver wants to creep or start again.
The method monitors the torque difference between the torque requested by the clutch and the torque of the engine in real time, and takes the torque difference as a judgment criterion to further calculate pressure compensation, so that the problem of shaking after brake due to clutch hysteresis is solved, and meanwhile, the idling oil consumption is reduced; after entering the hysteresis compensation state, the brake pressure and the EPB state are detected at all times to further judge the driving intention, and when the reptation or restart intention is judged, the compensation can be reset quickly to ensure the response. The invention adopts closed-loop control, avoids the problem that the single calibration cannot cover the hysteresis change in the whole service life of the clutch, is beneficial to the development of calibration work and ensures that the vehicle has stable driving performance.
Fig. 6 is a block diagram showing a configuration of a control device for a clutch of a vehicle according to an embodiment of the present invention. As shown in fig. 6, the control device includes: a detection unit 1 and a control unit 2, wherein the detection unit is used for: detecting a vehicle speed of the vehicle; detecting a requested torque of the clutch and a torque of an engine of the vehicle when a vehicle speed of the vehicle drops to 0; the control unit is configured to control negative pressure compensation of a target pressure of the clutch when an absolute value of a difference between a requested torque of the clutch and a torque of the engine is greater than a torque threshold.
Further, the control unit is further configured to: controlling the value of the negative pressure compensation to increase from 0 to perform the negative pressure compensation on the target pressure of the clutch.
Further, after controlling the value of the negative pressure compensation to increase from 0 to perform the negative pressure compensation on the target pressure of the clutch, the control unit is further configured to: controlling the value of the negative pressure compensation to stop increasing when an absolute value of a difference between the requested torque of the clutch and the torque of the engine is equal to or less than the torque threshold.
Further, after the control of the negative pressure compensation of the target pressure of the clutch, the detection unit is further used for detecting the brake pressure or the hand brake state; and the control unit is also used for stopping carrying out negative pressure compensation on the target pressure of the clutch when the brake pressure is smaller than the pressure threshold value or the hand brake state is released.
