Abstract

The invention discloses a clutch closed-loop control system of double clutch gearbox and a control method thereof, belonging to the technical field of automobile gearbox and comprising: an oil pressure sensor, a PI controller and an adder, wherein the oil pressure sensor is fixedly arranged in a clutch actuating valve and outputs a hydraulic oil pressure signal to the PI controller, a signal output end of the PI controller is connected with an input end of the adder and outputs a feedback current and a target current, a signal receiving end of the PI controller is connected with an output endof the adder and receives a current erroneous value, and an instruction output end of the PC controller is connected with the clutch actuating valve and outputs a control current. The clutch closed-loop control system of double clutch gearbox overcomes the problems of being easily influenced by various interferences, inferior accuracy and the like in current closed-loop system, simplifies multi-controller structure in closed-loop system and enhances response time and reliability of the system.

Description

technical field [0001] The present invention relates to a system and method in the technical field of automobile transmission, in particular to a clutch closed-loop control system and control method of a dual-clutch transmission. Background technique [0002] Automotive transmissions mainly include manual transmissions and automatic transmissions. Among them, the manual transmission (MT), also known as manual transmission, can only change the meshing position of the gears in the transmission and change the transmission ratio by turning the shift handle by hand, so as to achieve the purpose of speed change. When the clutch pedal is depressed, the shift handle can be moved. If the driver is skilled, a car equipped with a manual transmission will be faster than an automatic transmission model when accelerating and overtaking, and it also has an advantage in fuel economy. The automatic transmission (AT) uses mechanisms such as planetary gears and hydraulic torque converters to...
