For solving the problems referred to above, technical solution of the present invention provides the startup control method of a kind of electromotor。
Fig. 1 is the schematic flow sheet of the startup control method of the electromotor that technical solution of the present invention provides, as it is shown in figure 1, step S1 is first carried out, when needs start electromotor, initiates engine start instruction。
Hybrid power control unit is based on the power demand of current hybrid power system, it is determined whether need to start electromotor。System signal when hybrid power control unit can travel according to collected vehicle, calculates the power demand of hybrid power system in real time。Described system signal includes the drivable position etc. of the accelerator pedal signal of hybrid power system, the travel speed of vehicle, vehicle, described hybrid power control unit can determine current power demand according to described system signal, and then provides the instruction of the intervention the need of electromotor。In order to the power demand of described hybrid power system can be obtained more accurately, when determining the power demand of hybrid power system, can also in conjunction with anti-lock braking system (ABS, Anti-lockedBrakingSystem) signal, engine water temperature signal and noise, vibration and sound vibration roughness (NVH, NoiseVibrationHarshness) signal etc. carry out many-sided consideration, and then accurately to obtain the power demand of hybrid power。
When hybrid power control unit is determined by calculating and to be needed to start electromotor, initiate engine start instruction, perform step S2 afterwards。
Step S2, makes the first clutch between described electromotor and change speed gear box enter the sliding wear stage, to control the rotating speed of described electromotor。
In technical solution of the present invention, by arranging clutch between the engine and the gearbox, as in figure 2 it is shown, by the sliding wear of clutch, drive engine rotation, and then realize smooth starting electromotor。In present specification, the clutch that will be located between electromotor and change speed gear box is called first clutch。Described first clutch includes single plate clutch or multiplate clutch。
After hybrid power control unit initiates engine start instruction, by power source existing in hybrid power system, the power source that such as drive motor (as shown in Figure 2) provides, drives first clutch to carry out sliding wear by change speed gear box, makes described first clutch enter the sliding wear stage。Clutch or alternate manner etc. can be passed through between described drive motor and change speed gear box be attached。
By the sliding wear of first clutch, described electromotor is driven to carry out rotating (now electromotor is also not actuated), the energy source of engine rotation friction torque on first clutch, the size of the pressure that control is applied on first clutch can be passed through, the size of the friction torque on control first clutch, and then realize the control of the rotating speed to electromotor。
For example, when the pressure being applied on first clutch changes, then the friction torque on first clutch also can change, sliding wear rotating speed between first clutch and electromotor can change, and then the rotating speed of electromotor also can change, the control of the rotating speed to electromotor can be realized with this。
Perform step S3, when the rotating speed of described electromotor reaches the rotating speed of target of electromotor, first clutch described in locking, initiate electromotor oil spout firing command, and utilize drive motor that output shaft rotating speed is carried out stabilization control, to complete the startup of described electromotor。
The rotating speed of target of described electromotor is associated with the output shaft rotating speed of described change speed gear box, so that electromotor can be linked in hybrid power system when starting smoothly, so should when the rotating speed of electromotor is consistent with the rotating speed of target of electromotor, first clutch described in locking, make electromotor full access to, in the drive system of hybrid power system, now controlling electromotor oil spout igniting。After initiating electromotor oil spout firing command, owing to would be likely to occur when electromotor oil spout is lighted a fire, the rotating speed of electromotor there will be less fluctuation, in order to ensure the stability of output shaft rotating speed, now by the drive motor in hybrid power system, output shaft rotating speed can be carried out stabilization control, and then complete engine start。
The startup control method of the electromotor that technical solution of the present invention provides, drive engine rotation by the sliding wear of described first clutch, and then when the rotating speed of electromotor reaches rotating speed of target, start electromotor, can quickly, smooth starting electromotor, promote engine start ride comfort。
Understandable for enabling the above-mentioned purpose of the present invention, feature and advantage to become apparent from, below in conjunction with accompanying drawing, specific embodiments of the invention are described in detail。
Fig. 3 is the schematic flow sheet of the startup control method of the electromotor that the embodiment of the present invention provides, as in figure 2 it is shown, step S301 is first carried out, it is determined that the power demand of hybrid power system。
System signal when hybrid power control unit can travel according to collected vehicle, calculates the power demand of hybrid power system in real time。
Perform step S302, it may be judged whether need engine start。
When the power demand of hybrid power system is relatively larger time, time the power that relying only on drive motor provides cannot meet the power demand of system, it is determined that need described engine start, perform step S303；Otherwise return and perform step S301, continue to obtain the power demand of hybrid power system。
Step S303, initiates engine start instruction。
When the power demand based on present hybrid system, it is determined that when needing to start electromotor, hybrid power control unit initiate engine start instruction。
Hybrid power control unit can based on the power demand of present hybrid system, the rotating speed of the drive motor in control hybrid power system。The rotating speed of target of electromotor is output shaft rotating speed after change speed gear box speed ratio converts, and can be provided rotating speed during engine start by hybrid power control unit with this, i.e. the rotating speed of target of electromotor。
Performing step S304, the power source provided by the drive motor in hybrid power system drives described first clutch to carry out sliding wear, makes described first clutch enter the sliding wear stage。
The power source that can be provided by the drive motor in hybrid power system, drives first clutch to carry out sliding wear by change speed gear box, makes described first clutch enter the sliding wear stage。Specifically, hybrid power control unit can according to the rotating speed of target of electromotor, in conjunction with the water temperature information of electromotor, first clutch oil temperature information etc., control first clutch cylinder pressure and promote first clutch sheet to get involved the sliding wear stage, it is achieved driven the rotation of electromotor by the sliding wear of first clutch。
Perform step S305, regulate and control the pressure of described first clutch cylinder pressure。
In the present embodiment, described first clutch can adopt oil clutch, it is possible to realize the control of the pressure to described first clutch cylinder pressure by regulating and controlling the oil pressure of described first clutch cylinder pressure。
In order to realize the control for engine speed, it is possible to by regulating and controlling the size of the pressure being applied on first clutch, it is achieved the control of the sliding wear rotating speed of described first clutch, and finally realize the control for engine speed。
For example, it is possible to the oil pressure of described first clutch cylinder pressure is regulated and controled based on proportional-integral-differential (PID, ProportionIntegrationDifferentiation) algorithm。When the oil pressure of described first clutch cylinder pressure being regulated and controled with described pid algorithm, the input value of described pid algorithm can be determined based on the difference between engine speed rate of change and target revolution speed variation rate, pid algorithm can based on described input value, provide a regulation and control oil pressure, and then realize the regulation and control of the oil pressure to described first clutch cylinder pressure based on this regulation and control oil pressure。
The rate of change of described engine speed can obtain based on the engine speed that hybrid power system obtains in real time, and described target revolution speed variation rate can be determined according to the sliding wear torque capability of the torque capability of current drive motor and described first clutch。Such as, when the torque capability of described drive motor is bigger, and described first clutch is under current pressure effect, when sliding wear torque capability is also big, then the target revolution speed variation rate of described electromotor accordingly can be relatively larger, otherwise, if the torque capability of described drive motor is less, and described first clutch is under current pressure effect, when sliding wear torque capability is also little, then the target revolution speed variation rate of described electromotor accordingly can be smaller。
In step S305, can using square value of the absolute value of the difference between engine speed rate of change and target revolution speed variation rate or difference etc. as the input value of pid algorithm, with the regulation and control oil pressure given by pid algorithm, the oil pressure of described first clutch cylinder pressure is regulated and controled, it is achieved the regulation and control to the pressure of described first clutch cylinder pressure。
Perform step S306, based on the sliding wear rotating speed of first clutch described in the Stress control of described first clutch cylinder pressure。
When the pressure of described first clutch cylinder pressure changes time, friction torque on corresponding described first clutch also can change, and then cause that the sliding wear rotating speed of described first clutch changes, so can based on the oil pressure of first clutch cylinder pressure described in the regulation and control oil pressure real-time monitoring given by pid algorithm, it is achieved for the control of the sliding wear rotating speed of described first clutch。
It should be noted that act on the pressure of first clutch cylinder pressure except the regulation and control oil pressure given by pid algorithm, hybrid power system itself is also had to be supplied to the pressure of first clutch。In the process that vehicle travels, hybrid power system can provide certain pressure to first clutch, and this pressure exists in the process that vehicle runs always, and the size of pressure is the different changes of the travel situations according to vehicle。The pressure of the be supplied to first clutch of described hybrid power system is it can be appreciated that be the feedforward oil pressure of described first clutch。
Perform step S307, based on the rotating speed of the sliding wear rotating speed described electromotor of control of described first clutch。
First clutch owing to being between electromotor and change speed gear box is in the sliding wear stage, when the sliding wear rotating speed of described first clutch changes, the rotating speed inevitably resulting in coupled electromotor also changes, and can realize the control of the rotating speed for described electromotor based on the sliding wear rotating speed of described first clutch。
Perform step S308, it is judged that whether the relative speed variation of electromotor is consistent with the target revolution speed variation rate of electromotor。
In order to realize the effect that better smooth engine starts, based on pid algorithm in the process of the regulation and control of engine speed, whether the relative speed variation that can monitor electromotor in real time is consistent with the target revolution speed variation rate of electromotor, if the relative speed variation of electromotor is consistent with the target revolution speed variation rate of electromotor, illustration pressure on described first clutch enough meets the demand of engine speed rate of change, without continuing to regulate and control the pressure of described first clutch cylinder pressure, can stop regulating and controlling the pressure of described first clutch cylinder pressure based on pid algorithm, namely it is yes in the judged result of step S308, then perform step S309；Otherwise return and perform step S305, continue to regulate and control the pressure of described first clutch cylinder pressure。
Step S309, it is judged that whether the rotating speed of electromotor reaches rotating speed of target。
When engine speed rate of change is consistent with target revolution speed variation rate, the rotating speed of possible electromotor is but without the rotating speed of target reaching electromotor, pressure is provided for first clutch owing to hybrid power system can have been based on Current vehicle travel situations, based on this pressure, the sliding wear rotating speed of first clutch still may proceed to change, the rotating speed of electromotor is also to continue with change, so when the judged result of step S309 is no, step S310 can be performed, continue to monitor the rotating speed of described electromotor, the situation of change of the rotating speed of real-time judge electromotor。
In step S309 judged result for, when being, illustrating that the rotating speed of now electromotor has reached rotating speed of target, then can perform step S311。
Step S310, monitors the rotating speed of described electromotor。
The rotating speed of electromotor is but without, when reaching the rotating speed of target of electromotor, continuing to monitor the rotating speed of described electromotor, in the process of monitoring, it is possible to returns and continues executing with step S308 and subsequent step, until the rotating speed of electromotor reaches the rotating speed of target of electromotor。
Step S311, first clutch described in locking, initiate electromotor oil spout firing command, and utilize drive motor that output shaft rotating speed is carried out stabilization control, to complete the startup of described electromotor。
If the rotating speed of electromotor has reached the rotating speed of target of electromotor, then now can smooth starting electromotor, complete the sliding wear of first clutch, first clutch described in locking, electromotor oil spout light a fire。The stability of output shaft rotating speed during in order to ensure engine start, so can utilize drive motor that output shaft rotating speed is carried out stabilization control, for instance, when there is fluctuation in output shaft rotating speed, torque forward or backwards is additionally applied so that output shaft remaining stable for property of rotating speed by drive motor。After the startup completing described electromotor, the power of drive motor and electromotor cooperation, drive motor and electromotor is delivered to driving wheel by change speed gear box, completes the driving to vehicle。
It should be noted that, in the present embodiment, enter the sliding wear stage at first clutch, and control in the process of rotating speed of electromotor, pid algorithm completes the control for engine speed based on the speed discrepancy of electromotor and the relative speed variation of electromotor so that the process of engine start is quick and steady。
In other embodiments, after first clutch enters the sliding wear stage, control in the press process of first clutch, the rotating speed that can also be directly based upon electromotor is controlled, whether the relative speed variation without calculating electromotor is consistent with the target revolution speed variation rate of electromotor, directly judge whether the rotating speed of electromotor reaches rotating speed of target, when the rotating speed of electromotor reaches rotating speed of target, i.e. locking first clutch, complete the startup of described electromotor, equally possible quickly, smoothly complete engine start。
