Problems solved by technology

[0005] At present, most cars use hydraulic transmission automatic transmission (AT). The disadvantage of this automatic transmission is that the shifting efficiency is low.
Continuously variable transmission (CVT) solves the problem of low efficiency of hydraulic transmission automatic transmission, but the manufacturing cost is relatively high, and it is generally used in high-end cars

Embodiment Construction

[0026] In the present invention, when the system is powered on, the signal acquisition module first acquires whether the current driving mode is manual or automatic. If it is a manual driving mode, when the self-learning function is not turned on, the microprocessor will drive the corresponding shift solenoid valve to complete the shifting operation according to the driver's gear switching signal. After the self-learning function is turned on, the electronic control device can self-learn driving. The operator's operating habits, including shift habits, the relationship between driving speed and engine speed data, etc., and send the collected data to the microprocessor. For the model database, the data is stored in the data storage module. When the driver selects the automatic driving mode, the microprocessor samples and analyzes the engine speed, vehicle speed, throttle opening and other signals, matches with the model in the database, generates shift control parameters, and t...

Abstract

The invention aims at solving a technical problem of providing an electronic control device and a realization method of an automatic automobile transmission of manual automatic integration. The electronic control device of the automatic automobile transmission of manual automatic integration comprises a microprocessor module, a power supply module, a signal collection module, a power drive module, a data storage module and a CAN transceiver module. The invention designs various stable and reliable signal collecting and processing circuits, adopts an optimal control method, designs the function of fault self-diagnosis and causes the controller to be characterized by fast and accurate gear shifting, stable and reliable work, etc. At the same time, an external data storage module and the CAN transceiver module are added, which causes the design to have good scalability. Based on the existing hydraulic transmission automatic transmissions (AT), the electronic control device improves the efficiency of gear-shift operation and has the advantages of good production inheritance, low investment cost, high efficiency, easy manufacturing, convenient control, etc.

Description

technical field [0001] The invention relates to a comprehensive technology of signal collection, signal centralized processing, CAN communication, intelligent control, etc., and in particular to an electronic control device of an automatic manual transmission and a realization method thereof. Background technique [0002] At present, the automobile transmission system is mainly divided into three modes: manual, automatic, and automated manual. [0003] Traditional manual transmission has good driving dynamics and economy, but due to the labor-intensive shifting operation, especially in complex road conditions, it is easy to distract the driver's attention and increase traffic accidents. Moreover, due to differences in the level of shifting skills of drivers, there are huge differences in the fuel economy, power and pollution emissions of the entire vehicle, resulting in increased environmental pollution and waste of energy. [0004] Automatic transmission has the advantages...
