A clutch slip control device and control method

Abstract

The invention discloses a clutch sliding friction control device and a control method. The device comprises a clutch, a hydraulic device and a fuzzy controller; There is a pressure sensor, and the hydraulic device includes an oil pump; the oil inlet of the oil pump is connected with the oil tank; the oil outlet of the oil pump is connected with the oil port P of the solenoid valve through the oil inlet pipe; the oil port A of the solenoid valve is connected with the oil inlet of the one-way valve I , the oil port T of the solenoid valve communicates with the oil tank; the oil outlet of the check valve I communicates with the oil inlet and outlet of the clutch through the oil pipe, and the oil pipe is connected to the accumulator through the pipeline; the oil inlet pipe is connected with the electromagnetic proportional pilot overflow through the pipeline The oil inlet of the valve, the oil pipe connecting the one-way valve I and the clutch is connected to the external control port of the electromagnetic proportional pilot relief valve through the pipeline. The invention has the advantages of simple structure and high control precision, so that the clutch always works in the best sliding friction zone, and realizes the balance between the dynamic performance and the smoothness of the clutch.

Description

technical field [0001] The invention belongs to the technical field of clutch control, and in particular relates to a clutch slip control device and a control method. Background technique [0002] The starting clutch enables the gradual engagement between the engine and the transmission, thereby ensuring a smooth start of the car. The clutch combination can rigidly transmit the power output from the engine to the gearbox, which improves the system transmission efficiency and reduces energy loss, but it also brings adverse consequences, because the noise and vibration caused by the torque fluctuation generated by the engine fuel combustion It will be directly transmitted to the drive train of the car, reducing the comfort of the ride, the handling of the car and the life of the drive train. On the other hand, when the clutch is disengaged, the transmission of engine torque fluctuations to the drive train is effectively blocked, but because part of the power of the engine is ...

The clutch combination can rigidly transmit the power output from the engine to the gearbox, which improves the system transmission efficiency and reduces energy loss, but it also brings adverse consequences, because the noise and vibration caused by the torque fluctuation generated by the engine fuel combustion It will be directly transmitted to the drive train of the car, reducing the comfort of the ride, the handling of the car and the life of the drive train

On the other hand, when the clutch is disengaged, the transmission of engine torque fluctuations to the drive train is effectively blocked, but because part of the power of the engine is transmitted to the gearbox in the form of hydraulic power, a large amount of energy loss will occur
