AI Technical Summary

Technical Problem

When matching and carrying existing automatic transmissions, the wide variety of models leads to increased difficulty in product management and calibration parameter management, which easily leads to mismatch between controller and automatic transmission models, resulting in gear shift failure or damage.

Method used

By setting the automatic transmission data parameters, it is recorded in the memory according to the engine reference torque and the transmission first-speed ratio, read the engine reference torque and calculate the transmission first-speed ratio, set the automatic transmission parameters based on these data, and save the parameters in the The power can be saved in memory, making it possible to be compatible with multiple automatic transmission models with one version of software.

Benefits of technology

It greatly improves the adaptation range of the controller, reduces the targeted manpower and material consumption, reduces costs, and avoids the mismatch problem between the controller and the automatic transmission.

Abstract

The present invention provides a multi-model automatic transmission parameter control method, comprising the following steps: setting parameters: recording automatic transmission data parameters in a memory according to an engine reference torque and a first gear ratio of the transmission; reading parameters: reading the engine reference torque from an ECU, calculating the first gear ratio of the transmission, and setting the automatic transmission data parameters according to the engine reference torque and the first gear ratio of the transmission. The present invention also provides a multi-model automatic transmission parameter control system. The present invention can effectively realize that one version of software is automatically compatible with multiple automatic transmission models, greatly improve the adaptability range of the controller, reduce the manpower and material resources consumed by targeted settings, and thus greatly reduce costs.
