Electronic control unit for dry-type 5-speed-grade double clutch transmission and application thereof

Abstract

The invention relates to an electronic control unit for a dry-type 5-speed-grade double clutch transmission. The electronic control unit comprises a main control chip, a signal conditioning circuit and a power supply circuit, wherein the main control chip is respectively connected with the signal conditioning circuit and the power supply circuit; the main control chip comprises a CPU (central processing unit), a minimal system circuit, a clutch and a gear shift motor driven circuit, a double CAN (controller area network) communication circuit, an SPI (serial peripheral interface) circuit, an SCI (serial communications interface) circuit connected with a restrictor controller, an A / D (analog-to-digital) conversion module, an I / O input / output port, and an ECT (enhanced capture timer) module; and the CPU is respectively connected with the minimal system circuit, the clutch as well as the gear shift motor driven circuit, the double CAN communication circuit, the SPI circuit, the SCI circuit, the A / D conversion module, the I / O port, and the ECT module. Compared with the prior art, the electronic control unit provided by the invention has the advantages of low cost, high reliability and the like.

Description

technical field [0001] The invention relates to an electronic control unit of an automobile transmission and its application, in particular to an electronic control unit of a dry-type 5-speed double-clutch automatic transmission and its application. Background technique [0002] Dual Clutch Transmission (DCT for short) is developed on the basis of Automated Manual Transmission (AMT for short). It not only has better fuel economy, but also eliminates the power interruption problem of the vehicle during the gear shifting process, and at the same time improves the gear shifting comfort during the driving process of the vehicle. [0003] Dual-clutch automatic transmission actuators can be divided into two types: electro-hydraulic and electric. Electro-hydraulic actuators have the advantages of high control precision and large driving power, but there are complex system structures, high costs, and high installation and maintenance requirements. The working performance is greatly...

AI Technical Summary

Problems solved by technology

In view of the fact that the DCT transmission is currently in the research and development stage in China, there are almost zero patents and papers on the development of the DCT control unit TCU (Transmission control unit, referred to as TCU) in China, while foreign mainland electronics companies are relatively mature in the development of TCU, even Reaching the level of integration, that is, packaging the controller and the actuator together, but its research results have not applied for relevant patents in China
