Abstract

Provided are a hydraulic control system and control method of a transmission and an automobile. The hydraulic control system comprises a clutch control device, a synchronizer control device and a hydraulic oil supply device for supplying oil to the clutch control device and the synchronizer control device. Control of two clutches can be achieved by arranging a first pressure magnetic valve, a first clutch actuator, a second pressure magnetic valve and a second clutch actuator in the clutch control device, control of a synchronizer can be achieved by arranging a third pressure magnetic valve, a fourth pressure magnetic valve, a first logic valve, a second logic valve and multiple synchronizer actuators, the structure of the hydraulic control system is simplified, the cost is reduced, and the control process can be more reliable and convenient.

Description

technical field [0001] The invention relates to the technical field of automobiles, in particular to a hydraulic control system of a dual-clutch transmission, a hydraulic control system for controlling multiple synchronizers in a transmission, and a hydraulic control system for controlling multiple synchronizers in a transmission. device, and a vehicle. Background technique [0002] Dual Clutch Transmission (DCT for short) is a new type of transmission, which arranges the transmission gears on the two input shafts connected to the two clutches according to odd and even numbers, and completes the transmission through the alternate switching of the two clutches. gear process to realize power shifting. Dual-clutch transmission combines the advantages of hydraulic-mechanical automatic transmission and electro-mechanical automatic transmission. It has high transmission efficiency and simple structure, which not only ensures the power and economy of the vehicle, but also greatly ...
