Drawings
In order to more clearly illustrate the embodiments of the present application or the technical solutions in the prior art, the drawings that are required to be used in the embodiments or the description of the prior art will be briefly described below, and it is obvious that the drawings in the following description are only some embodiments described in the present application, and other drawings may be obtained according to these drawings without inventive effort for a person skilled in the art.
FIG. 1 is a flow chart of a method for adjusting clutch torque according to an embodiment of the present disclosure;
fig. 2 is a schematic structural diagram of a clutch torque adjusting device according to an embodiment of the present application.
Detailed Description
The inventor finds that for torque adjustment of the clutch, in the prior art, torque learning of the clutch is generally realized by adopting a microslip control technology of engine torque, and the torque of the clutch is controlled to cause microslip of the clutch, namely, when speed difference occurs at two ends of the clutch, the torque of the clutch is adjusted according to the torque of the engine at the moment. However, the engine used in the conventional automobile is a fuel engine, and the torque of the fuel engine is not stable, and there are many factors affecting the fuel engine, including the internal temperature, the external temperature, and the like of the fuel engine. In addition, the torque of the fuel engine is inconvenient to control, and when the clutch is controlled, the torque of the fuel engine is difficult to maintain accurate and stable. Therefore, the effect of adjusting the torque of the clutch according to the fuel engine is not good.
The inventor finds that the torque of the fuel engine has the problem of insufficient precision, so that data with higher precision is needed to be selected to adjust the torque of the clutch. The existing automobile has an oil-electricity integrated automobile, and compared with a fuel oil generator, the motor has more accurate torque and is easy to control. For a car with integrated fuel and electricity, an engine can be used to drive a motor to rotate, and electric energy is generated and stored in a battery of the car for use in running of the car. When the automobile is charged, the fuel engine and the motor are charged through a transmission device such as a clutch, so that the torque of the clutch can be adjusted through the torque of the motor.
In order to make the present application solution better understood by those skilled in the art, the following description will clearly and completely describe the technical solution in the embodiments of the present application with reference to the accompanying drawings in the embodiments of the present application, and it is apparent that the described embodiments are only some embodiments of the present application, not all embodiments. All other embodiments, which can be made by one of ordinary skill in the art without undue burden from the present disclosure, are within the scope of the present disclosure.
In order to facilitate understanding of the technical solution provided by the embodiments of the present application, a method for adjusting clutch torque provided by the embodiments of the present application is described below with reference to the accompanying drawings.
Referring to fig. 1, a flowchart of a method for adjusting clutch torque according to an embodiment of the present application may include:
s101: and controlling the vehicle to carry out parking charging.
It should be noted that, when the car of oil electricity integration carries out parking and charges, the fuel engine can drive the motor and generate electricity, at the in-process that charges, can carry out the transmission through the clutch between fuel generator and the motor.
It will be appreciated that the vehicle may be confirmed to meet the park charge condition prior to the control of the vehicle to park charge. The parking charging condition may be that a vehicle speed is zero, a brake pedal opening is greater than or equal to a preset opening threshold, and an electric quantity of the power battery is less than a preset electric quantity. The vehicle speed is zero, and the opening of the brake pedal is greater than or equal to a preset opening threshold value, so that the vehicle is in a parking state or a parking state, wherein the preset opening threshold value can be set according to the parking requirement. The electric quantity of the power battery in the parking charging condition is smaller than the preset electric quantity, so that the automobile can be parked and charged, and the preset electric quantity can be any value smaller than the maximum electric quantity of the battery.
It should be noted that, when the vehicle meets the charging condition of parking, the vehicle may be triggered to perform parking charging, and in one possible implementation, the parking charging may be performed by triggering a controller in the vehicle.
The method comprises the steps of controlling a vehicle to carry out parking charging, specifically, firstly controlling a synchronizer in a power coupling device of the vehicle to adjust the input shaft teeth of an engine, closing a clutch, and enabling a transmission relation between the engine and a motor to be established; and restarting the engine, keeping the rotating speed of the engine to be a first rotating speed, calculating the initial torque of the motor according to the first rotating speed and the charging power of the vehicle, and controlling the torque of the motor to be the initial torque. In the power coupling device of the vehicle, the engine and the motor can adjust an input shaft and an output shaft between the engine and the motor through a synchronizer so as to drive the vehicle by the engine and the motor or realize charging by dragging the motor by the engine to generate electricity. Therefore, before the parking charge is carried out, the synchronizer is controlled to adjust the input shaft teeth of the engine, and the clutch is closed, so that a transmission relation is established between the engine and the motor. After the engine is started, the rotating speed of the engine is controlled, so that the rotating speed of the engine maintains the first rotating speed, the initial torque of the motor is calculated according to the relation between the torque and the ratio of the charging power to the first rotating speed, and the torque of the motor is controlled to be the initial torque, so that the parking charging function of the vehicle is realized.
S102: and controlling the clutch to reduce torque, and when the speed difference of the two ends of the clutch is larger than or equal to a first threshold value, acquiring the current torque of the motor and acquiring the shaft speed ratio of the motor to the engine.
In one possible implementation, before the control clutch reduces torque, determining whether the clutch satisfies an adjustment state, wherein the adjustment state is that the torque of the clutch is greater than or equal to an adjustment threshold and there is no speed difference at two ends of the clutch; and if the adjustment state is met, triggering the control clutch to reduce the torque. It can be understood that, before the clutch is adjusted, it is first determined whether the clutch satisfies the adjustment state, and since the adjustment of the torque is required in the state that the clutch is slightly slippery, it is required to determine that the torque of the clutch is sufficient to perform the adjustment of the torque before the adjustment, that is, the torque of the clutch is greater than or equal to the adjustment threshold, and the adjustment threshold can be set according to the adjustment requirement of the clutch. And before adjustment, the clutch needs to keep no speed difference at two ends, namely the rotation speeds of the motor and the engine are not different, and the clutch can normally rotate and does not generate a sliding state.
It should be noted that, the clutch may be controlled to reduce the torque according to a preset decreasing value. The preset decreasing value can be set according to the torque adjustment requirement of the clutch, the torque decrease of the clutch can be controlled to be decreased by one preset decreasing value each time, whether the speed difference at two ends of the clutch is larger than or equal to a first threshold value is judged, if the speed difference at two ends of the clutch is not larger than or equal to the first threshold value, the torque of the clutch is continuously decreased by one preset decreasing value until the speed difference at two ends of the clutch is larger than or equal to the first threshold value.
The ratio of the motor to the engine is determined by the transmission of the vehicle and may be obtained from the transmission of the engine to the motor.
S103: and calculating a torque correction value of the clutch according to the shaft speed ratio and the current torque of the motor, and adjusting the torque of the clutch according to the torque correction value.
In one possible implementation, the torque correction value of the clutch may be obtained from a product of the shaft speed ratio and a current torque calculation of the motor. The torque of the clutch may be adjusted by adjusting a torque estimation parameter of the clutch according to the torque correction value.
In the embodiment of the present application, the condition for adjusting the clutch torque is not limited, and the clutch torque may be adjusted during the parking charge after the vehicle travels a certain mileage, or may be adjusted during the parking charge after a certain time.
