Detailed description of the invention
Below in conjunction with accompanying drawing, the specific embodiment of the present invention is described in detail, it is to be understood that protection scope of the present invention is not by the restriction of detailed description of the invention.
As in figure 2 it is shown, the clutch double-valve control system of the hybrid vehicle of the present invention includes entire car controller HCU, clutch controller 1, cleaner 2 and wheel cylinder cylinder 3.
As in figure 2 it is shown, clutch controller 1 includes the first electromagnetic valve 11 and the second electromagnetic valve 12, the first electromagnetic valve 11 is provided with throttle orifice 111. The gas outlet of the first electromagnetic valve 11 merges with the air inlet of the second electromagnetic valve 12, and is connected with the air inlet of wheel cylinder cylinder 3. Cleaner 2 passes to wheel cylinder cylinder 3 through the first electromagnetic valve 11 after the high pressure gas in car load cylinder being filtered, and the high pressure gas in wheel cylinder cylinder 3 is discharged by the air inlet of the second electromagnetic valve 12 or the throttle orifice 111 of the first electromagnetic valve.
Entire car controller HCU sends instructions to clutch controller 1, and clutch controller 1 is turned on and off the first electromagnetic valve 11 or the second electromagnetic valve 12 after receiving instruction, controlling to enter the high pressure gas of wheel cylinder cylinder 3, thus controlling push rod 31, making clutch separation or combination.
The clutch double-valve control system of the hybrid vehicle of the present invention has " dividing soon ", " closing soon ", " half-clutch " three kinds of states,
When entire car controller HCU sends " dividing soon " instruction, the first electromagnetic valve 11 is energized, and the second electromagnetic valve 12 power-off, high pressure gas enters wheel cylinder cylinder 3 through the first electromagnetic valve 11, and push rod 31 quickly pushes clutch open.
When entire car controller HCU sends " closing soon " instruction, the first electromagnetic valve 11 power-off, the second electromagnetic valve 12 is energized, and the high pressure gas in wheel cylinder cylinder 3 is quickly discharged through the second electromagnetic valve 12, and push rod 31 makes clutch quickly combine.
In high voltage component fault, motor cannot when speed governing, entire car controller HCU sends " half-clutch " starting instruction, control program first calls " closing soon " instruction, performing " closing soon " after a period of time, control routine call " closing slowly " instruction, i.e. the first electromagnetic valve 11 power-off, second electromagnetic valve 12 also power-off, high pressure gas in wheel cylinder cylinder 3 is slowly discharged by the throttle orifice 111 of the first electromagnetic valve 11, push rod 31 makes clutch slow fixation, in clutch both sides rotating speed essentially identical (as: speed discrepancy is 50 revs/min) time clutch directly in conjunction with.
Half-clutch state is to be realized by the reasonable time proportioning of " closing soon " and " closing slowly " two states, and the two ratio performing the time is determined by the concrete structure of different automobile types, and is preset in the control program of entire car controller HCU.
Fig. 3-5 illustrates that " soon close " and " closing slowly " time distribution is on the clutch impact in conjunction with effect, and in figure, transverse axis is the time (s), and the longitudinal axis is rotating speed (r/min), and clutch starts combination from a point, and b point is in conjunction with complete, and automobile completes to start to walk.
As it is shown on figure 3, " closing soon " time distribution is longer, engine speed dramatic decrease in cohesive process, final engine misses;
As shown in Figure 4, the distribution of " soon close " time is shorter, and in cohesive process, transmission input shaft rotating speed repeatedly intersects raising and reducing, final vehicle starting, and the interval of a-b is longer, it is easy to produce to slip by slope.
As it is shown in figure 5, " closing soon " time is moderate, in cohesive process, transmission input shaft rotating speed steadily improves, and engine speed steadily reduces, and the interval of a-b is shorter relative to Fig. 4 and starting is steady.
The present invention is provided with two electromagnetic valves in clutch controller, and " dividing soon " and " closing soon " is realized by different electromagnetic valves, makes " half-clutch " starting easily realize, improves the safety guarantee of vehicle under automobile high voltage component failure condition; Eliminate relay valve simultaneously, make the structure of the clutch control of hybrid vehicle simplify, reduce cost, decrease trouble point simultaneously, be conducive to maintenance.
