Problems solved by technology

Manual driving can judge the clutch opening and closing through human senses. However, for unmanned driving control manual transmission, it can only be fully automated. However, the existing automatic control manual transmission is often slow in clutch speed and not stable enough to start. Not good, and it is also prone to stalling at start

Embodiment 1

[0081] In order to realize clutch control, including mechanical mechanism, hardware circuit and software program;

[0082] In terms of mechanical structure, a large torque motor is used to drive the liquid crystal booster pump to promote the clutch action to achieve the effect of electronically controlled clutch;

[0083] The clutch is mainly composed of four parts: the active part (flywheel, clutch cover, etc.), the driven part (friction plate), the pressing mechanism (diaphragm spring) and the hydraulic push mechanism. Most of the clutches matched with the manual transmission are dry friction. Formula clutch, the present invention is also controlled at this type of clutch;

[0084] On the hardware circuit, it is mainly composed of a motor driver, a motor angle Hall sensor and a processor. The digital signal of the motor angle is collected through analog-to-digital conversion, and the output is controlled according to the algorithm;

[0085] In the software program, the inno...

Embodiment 2

[0115] The difference between this embodiment and Embodiment 1 is that the S4 is further defined to include:

[0116] subdividing the target engagement position into a plurality of sub-target positions according to the half-clutch position and the target engagement position;

[0117] For example, the half-clutch position is half_pos, and the target engagement position is whole_pos, then the half-clutch position to the target engagement position can be subdivided into multiple sub-target positions as required, assuming it is divided into 5 sub-positions, sub_pos1, sub_pos2, sub_pos3, sub_pos4, sub_pos5,

[0118] Then sub_pos(n)=half_pos+n*(whole_pos-half_pos) / 5;

[0119] Controlling the clutch to advance to the plurality of sub-target positions sequentially at the second preset speed, that is, to sequentially reach sub_pos1, sub_pos2, sub_pos3, sub_pos4, sub_pos5;

[0120] S41. During the propulsion process, read the current engine speed in real time:

[0121] Determine whether...

Embodiment 3

[0126] Please refer to figure 2 , a clutch control terminal 1, including a memory 2, a processor 3, and a computer program stored in the memory 2 and operable on the processor 3, when the processor 3 executes the computer program, the first embodiment or implementation Steps in Example 2.

[0127] To sum up, the clutch control method and terminal provided by the present invention include two modes, fast control and stable control, in the process of clutch control. For different stages of control, it is divided into front section, middle section and rear section. The middle section is near the half-clutch position. The front section adopts the fast control mode, and the middle section switches to the stable control mode. When the clutch slippage is less than the preset value, it enters the rear section. The fast control mode is adopted for the whole process, and the clutch fast and stable control is completed in the whole process. During the clutch combination process, at the...

Abstract

The present invention discloses a clutch control method and a terminal, which control the quick disengagement of the clutch at a first preset speed; perform gear shifting according to the received target gear; and control the quick closing of the clutch to a half-clutch position at the first preset speed ; Control the clutch to advance toward the target engagement position at a low speed at a second preset speed. During the low-speed propulsion process, calculate the clutch slippage in real time. When the clutch slippage is less than a preset value, use the first preset Set the speed to control the clutch to quickly engage to the target engagement position; during the clutch engagement process, at the beginning and end stages, the clutch is quickly engaged to reduce the clutch movement time in the whole process, and the clutch is half-engaged to stably control the clutch to make the vehicle speed and rotation speed match stably , so as to make the vehicle run stably. Through the fast and stable clutch control, the stability and comfort of starting can be realized, the situation of stalling at the start can be avoided, and the starting quality can be fully improved. The fast and reliable control of the clutch can increase the shifting speed.

Description

technical field [0001] The invention relates to the field of vehicle control, in particular to a clutch control method and terminal. Background technique [0002] Diesel engines have many advantages such as long life, economy and durability, high torque at low speed, high safety, and environmental protection. At present, diesel engine vehicles on the market generally use manual shifting mechanism for speed change control to give full play to the advantages of diesel engines. Manual driving can judge the clutch opening and closing through human senses. However, for unmanned driving control manual transmission, it can only be fully automated. However, the existing automatic control manual transmission is often slow in clutch speed and not stable enough to start. Not good, and it is also prone to stalling at start. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide a clutch control method and a terminal to realize fas...
