Problems solved by technology

[0002] The dual-clutch automatic transmission is a power transmission transmission mechanism. Due to the unreasonable control of the existing dual-clutch automatic transmission, it cannot perform reasonable speed changes according to the road conditions and road traffic conditions, resulting in frequent failures and high temperature of the clutch friction plate. Short service life, high fuel consumption, etc.

Embodiment Construction

[0005] The present invention will be further described below in conjunction with specific embodiment:

[0006] Embodiment; when the distance measuring sensor detects that the front obstacle enters 5 meters, trigger the dual clutch automatic transmission control module to switch to the delay shift mode, and when the engine speed reaches or exceeds 2000 rpm in the delay shift mode, The dual-clutch automatic transmission is shifted to the next gear. When the distance of the obstacle in front reaches or exceeds 15 meters or the vehicle speed exceeds 35 kilometers per hour, the control module of the dual-clutch automatic transmission is triggered to switch to the quick shift mode. The control method in the climbing mode , when the slope sensor detects that the slope is 10 degrees, switch to the climbing mode. In the climbing mode, when the engine speed reaches or exceeds 1800 rpm, the dual-clutch automatic transmission moves to the next gear. When the slope sensor detects that the s...

Abstract

The invention relates to the field of double-clutch automatic transmissions (DCT / DSG), in particular to an intelligent double-clutch automatic transmission control method. The invention aims to provide the dual-clutch automatic transmission used under different road conditions and different traffic environments, and the dual-clutch automatic transmission has the advantages that normal use under complex road traffic and different road conditions can be met, the failure rate of the dual-clutch automatic transmission is greatly reduced, high-efficiency power transmission of the dual-clutch automatic transmission can be completely achieved, and the accelerated reaction is fast. According to the more intelligent dual-clutch automatic transmission and the control method, a dual-clutch automatic transmission control module has three control modes, the first control mode is a delayed gear shifting mode, the second control mode is a climbing mode, and the third control mode is a rapid gear shifting mode; and the control mode is selected through data of a forward ranging sensor, a grade sensor, a vehicle speed sensor and an engine sensor, so that the dual-clutch automatic transmission works in an optimal mode.

Description

Technical field: [0001] The invention relates to the field of dual-clutch automatic transmission (DCT / DSG), in particular to an intelligent dual-clutch automatic transmission control method. Background technique: [0002] The dual-clutch automatic transmission is a power transmission transmission mechanism. Due to the unreasonable control of the existing dual-clutch automatic transmission, it cannot perform reasonable speed changes according to the road conditions and road traffic conditions, resulting in frequent failures and high temperature of the clutch friction plate. Short service life, high fuel consumption and other issues. Invention content: [0003] The purpose of the present invention is to provide a dual-clutch automatic transmission that can be used under different road conditions and different traffic environments, which can not only meet the normal use of complex road traffic and different road conditions, greatly reduce the failure rate of the dual-clutch a...
