The embodiment provides a hydraulic control system and a corresponding start-stop strategy, wherein the hydraulic control system consists of a high-pressure oil circuit, a gear switching oil circuit, a locking separation oil circuit, a lubricating oil circuit and a start-stop oil circuit. The main functions of the hydraulic system are as follows:
1. the switching state of 5 hydraulic actuating mechanisms (a first clutch, a second clutch, a third brake, a fourth brake and a fifth clutch) is controlled to realize the switching of the P/R/N/D gears, wherein the D gear is divided into six gears of D1/D2/D3/D4/D5/D6.

3. And the cooling/lubricating flow is controlled to realize the lubrication of each friction pair and the heat exchange of the gearbox assembly.
4. Through energy storage chamber solenoid valve, when needs use start-stop function, realize the steady combination of gearbox.
In order to realize the start-stop function and keep the stability of the start-stop combination, the hydraulic control system carries out hydraulic design on the start-stop oil path, and the specific composition of the hydraulic control system is shown in the diagram of the hydraulic system with the start-stop function in the figure 1. In the figure, 1, an accumulator switch valve; 2. an accumulator; 3. an energy storage spring; 4. an accumulator piston; 5. an accumulator check valve; 6. an accumulator throttle valve; 7, a main oil pressure electromagnetic valve; 8. A system pressure regulating valve; 9. a filter screen; 10. an oil tank; 11. an oil pump.
The implementation of the start-stop function of the hydraulic control system provided in this embodiment is divided into 3 stages.
The first stage is the accumulator oil filling stage, as shown in the state diagram of the oil filling process of the energy storage cavity in fig. 2.
The engine rotates to drive the oil pump 11 of the embodiment to normally work when the engine normally works, pressure oil is generated to enter a A, B port where the pressure regulating valve 8 of the system is located, the main oil pressure electromagnetic valve 7 normally works at the moment, controllable control oil pressure is output through current regulation, the main oil pressure is maintained in an ideal pressure value range, at the moment, if the pressure of the oil pump 11 is high, B, C is connected, part of the pressure oil is discharged into the oil tank 10, the pressure is reduced, the pressure of the port A is reduced, B, C is disconnected, and therefore the regulation of the main pressure is achieved, in the process, the main pressure oil enters an oil cavity of the accumulator 2 through the accumulator throttle valve 6, the accumulator piston 4 and the energy storage spring 2 move leftwards, the energy storage process is slowly performed due to the action of the accumulator throttle valve 6, the pressure of the system is not reduced, after a certain time, when the accumulator piston 4 reaches the piston position where the diagram is full, the piston is locked by a mechanical structure, the hydraulic energy is converted into elastic potential energy of the spring 2, and the energy storage process of the accumulator 2 is ended.
The second stage is an engine shutdown state, such as the hydraulic system maintenance state diagram of FIG. 3 when the engine is stopped.
When the engine is stopped, the oil pump 11 stops supplying oil, and the pressure oil of the actuator drops, which is insufficient to engage the clutch. At this time, the gearbox is still in D gear, and the accumulator is full of oil in the first stage. The accumulator piston 4 reaches a specified position and is mechanically locked, and the accumulator switching valve 1 is closed.
The 3 rd stage is an engine restarting stage, such as the hydraulic system working state diagram of the engine restarting of fig. 4.
When the engine is restarted, the engine speed reaches idle speed for a certain time, and in the process, the system pressure is slowly built up, and the volume of oil in the oil cavity is insufficient. At this time, the mechanical locking mechanism is opened by opening the accumulator switch valve 1, the accumulator 2 rapidly fills the oil in the accumulator piston 4 and the accumulator oil cavity into the closed space formed by the actuating mechanism and the main oil way under the action of the energy storage spring 3, so as to make up the oil shortage of the oil pump 11 at the starting moment, enable the actuating mechanism to be quickly combined, effectively reduce the impact during combination, and when the rotation speed of the engine reaches above the idle speed, the system pressure reaches a stable value, and the accumulator 2 reenters the first stage.
The accumulator also has a stabilizing effect on the system pressure. When the pressure oil generated by the oil pump fluctuates, the existence of the energy storage spring 2 can effectively absorb the fluctuation of the pressure, so that the system pressure tends to be stable.
The above embodiments are only for illustrating the technical idea of the present invention, and the protection scope of the present invention is not limited by the above embodiments, and any modification made on the basis of the technical scheme according to the technical idea of the present invention falls within the protection scope of the present invention; the technology not related to the invention can be realized by the prior art.
