Embodiment Construction

[0063] At present, at the starting stage, the vehicle needs to use the relative slip between the clutch master and the driven disc to increase the rotational speed of its transmission parts. But in this process, in order to make the vehicle start quickly, the engine speed is very high, and because the clutch is not in a fully engaged state, the driven plate of the clutch does not rotate synchronously with the driving plate, that is to say, the main, There is relative motion between the driven discs. And this kind of relative movement will lead to serious wear of the friction plate, and cause the temperature of clutch parts such as the pressure plate and flywheel to rise, and the excessive rise of the friction surface temperature will aggravate the wear of the friction plate, and affect the normal operation of the clutch, reducing the clutch wear. service life.

[0064] In order to explain the impact of the above conditions on the clutch, an example is given to illustrate the ...

Abstract

The invention relates to a control method and device for the rotating speed of a power source. The control method comprises the following steps of when the situation that the rotating speed of a driving disk of a clutch of a vehicle and the rotating speed of a driven disk of the clutch of the vehicle are different is determined, obtaining a current gear of the vehicle, and judging the abrasion degree of the driving disk of the clutch and the abrasion degree of the driven disk of the clutch; when the abrasion degree of the driving disk of the clutch and the abrasion degree of the driven disk of the clutch are greater than a preset degree, judging whether the rotating speed of the power source exceeds a preset threshold or not; and when the situation that the rotating speed of the power source exceeds the preset threshold is determined, adjusting the rotating speed of the power source to the preset threshold. Through the adoption a scheme of the control method and device disclosed by the invention, the abrasion of the clutch can be reduced, and the service life of the clutch is prolonged.

Description

technical field [0001] The invention relates to the field of engine speed control, in particular to a method and device for controlling the speed of a power source. Background technique [0002] Cars are playing an increasingly important role in modern society and have become an indispensable part of most people's daily lives. On a vehicle using a manual transmission (Manual Transmission, MT), the Electronic Control Unit (Electronic Control Unit, ECU) acts as the brain of the vehicle to control the vehicle. On vehicles with automatic transmissions, the automatic transmission control unit (Transmission Control Unit, TCU) is often used to control the electromechanical automatic transmission (Automated Mechanical Transmission, AMT), hydraulic automatic transmission (automatic transmission, AT), dual clutch Automatic transmissions such as an automatic transmission (Dual Clutch Transmission, DCT) and a continuously variable transmission (Continuously Variable Transmission, CVT) ...
