Problems solved by technology

[0004] After searching the existing technologies, it was found that Xu Xiuhua, Liu Wenzhong, Chen Yong, etc. published a document "Research on Shifting Strategies of Dual Clutch Automatic Transmissions" in the Proceedings of the 2009 China Society of Automotive Engineers Annual Conference. Only based on the current vehicle speed and accelerator opening, without considering external factors such as the rolling friction coefficient of the road surface, slope, wind speed, and vehicle body quality, it is impossible to make adaptive adjustments to the shift point based on these external parameters

Abstract

The invention relates to a self-adaption gear shifting device for a double-clutch automatic gearbox and a realizing method thereof which belong to the technical field of a vehicle gearbox. The device comprises a signal sampling unit, a control unit and an actuating mechanism, wherein the signal sampling unit is arranged in the vehicle gearbox in order to sample a driving parameter of the vehicle and output to the control unit; the control unit is arranged for receiving the driving parameter and outputting a shifting point self-adaption revision directive to the actuating mechanism according to the pavement condition; and the actuating mechanism is arranged for shifting the gearbox so as to realize the optimum matching of the vehicle shifting.

Description

technical field [0001] The present invention relates to a device and method in the technical field of automobile transmission, in particular to an adaptive gear shifting device for a Dual Clutch Automatic Transmission (DCT for short) and its realization method. Background technique [0002] The main goal of gear shift control of dual clutch automatic transmission is to minimize the number of times of disengagement and engagement under the premise of correctly realizing its corresponding functions, and to make the vehicle's economy, power and driving comfort optimally matched. [0003] In different driving conditions of DCT vehicles, the rolling friction coefficient of the road surface, slope, wind speed and vehicle body quality will change, but DCT vehicles will automatically shift gears after the vehicle speed reaches the shift point, while the traditional basic shift curve and The power shift curve cannot offset the influence of these operating conditions on the vehicle sp...
