Detailed description of the invention
The location that the electricity of hybrid vehicle drives speed change box clutch mainly refers to the location of kissing point. Here, kiss point refers to that clutch starts transmission torque and clutch torque is the clutch position of non-zero.
Drive in the adaptive location control of speed change box clutch moment kiss point at electricity, what first will determine is control problem on opportunity. Control and not only there is no need too frequently, and can waste energy, introduce extraly wearing and tearing. According to design of the present invention, starting the mode of positioning control has two kinds, and first driver sends the instruction of restarting moment and kiss point self-adapted renewal according to driving situation, and it two is to be started by a management kiss point study submodule for automobile control module. For the second way, management kiss point study submodule can be just to start the positioning control to each clutch after each key circulation. Here a key circulation refers to the pass from key, to operation, and to igniting, then to closing such a circulation. Or, substituting as one, automobile control module can be counted the number of times of gearshift, after the quantity that has reached predetermined is moved in gearshift, management kiss point study submodule startup positioning control. Here counting device can be arranged in the car running computer of automobile.
No matter positioning control by which kind of mode is started, after starting, for the smooth enforcement that ensures to control, the first essential a series of vehicle-state condition (Fig. 1 step 101) that detects, the order of detection can be as shown in Figure 2. First by car running computer, the position of gear level is judged, in the gears such as P/R/N/D/L, only have in the time that gear level is positioned at parking shelves (P gear) and just carry out follow-up judgement, otherwise finish this Positioning Process in step 201. Next, carry out speed of a motor vehicle judgement in step 202, just abandon this Positioning Process if the speed of a motor vehicle is greater than predetermined calibration value, no person enters next step judgement. In step 203, diagnosis default action state is checked subsequently, only in the time not diagnosing default action, just enter the judgement of step, otherwise finish this Positioning Process. Finally, do not shift gears in the definite current driver's of step 204, if driver shifts gears, finish this Positioning Process. After above-mentioned inspection is all passed through, system has been ready for positioning control.
Next enter kiss point initial value obtaining step (as shown in Fig. 1 102), first automobile control module controls machine operation in specific rotation speeds, the transmitting torque of setpoint clutch kiss point is torque limit, control makes clutch friction plate close, when motor speed starts to decline, experimental point is now clutch torque kiss point initial value.
Then, obtain adaptive updates value by initial value, by the position of adaptive updates value control moment kiss point. Now another should considered factor be yield value and side-play amount, and yield value and side-play amount are rule of thumb or the factor obtained of other approach, and it can be used as the amplification coefficient of adaptive updates value. Add side-play amount and can be controlled at the amplitude of the change using in the process of determining kiss point by be multiplied by kiss point initial value with amplification coefficient. It should be noted that excessive change must be suppressed. This be because, one, excessive change is likely because false judgment causes; Its two, this may exceed the regulating power of clutch self, and thereby causes the damage of device. Therefore,, when the adaptive updates value after amplifying is greater than predetermined maximum calibration renewal value, point out clutch to kiss point self-adapted inefficacy according to the mode of agreement.
Above-mentioned embodiment is by the control strategy development process based on model, can realize online verification and automatic code generates, the electricity that can effectively improve novel stroke lengthening hybrid power automobile drives gearbox shifting quality, reduces gearshift accident, makes hybrid vehicle safe operation.
