【摘要】：目前汽车自动变速箱参数调试系统的软件,多是由厂商自行设置研究开发。造成该现状的主要原因是各个车型的参数不同,软件的设置上会有很大变动。这就造成了无法用统一的软件来进行不同车型的调试。因此,迫切需要开发能够适用于多种车型的参数调试系统。本文开发的系统可以实现多种车型的参数调试与故障诊断,具有操作简单、灵活性好、兼容性高的特点。课题主要内容包括系统总体设计、硬件设计、软件设计和实车调试四部分。论文首先在理论上分析了参数调试及故障诊断系统的原理。提出了对变速箱内10个重要参数的设置以及变速箱故障诊断的相应方法。硬件电路设计中采用LPC2132单片机作为核心处理芯片,设计了矩阵键盘电路等,充分利用LPC2132内部集成的多路10位A/D、UART、定时计数器、I2C等功能模块,提高了电路集成度。软件程序设计主要是编写C语言程序,完成LCD12864液晶屏上各种调试诊断功能的操作。其中包括对AMT参数初始设置、参数修改、存储及其传输,AMT故障的分析判断,及其相关故障的显示等。系统经过实车调试和运行,实现了预期的功能。AMT参数调试及故障诊断系统,完成了对多种车型的参数调试与故障诊断,在AMT参数的调试以及故障维修方面有较高的的参考意义和良好的应用价值。
[Abstract]:At present, the software of automatic gearbox parameter debugging system is mainly set up by the manufacturer. The main reason for this situation is that the parameters of each vehicle are different, the software settings will be greatly changed. This makes it impossible to use unified software to debug different models. Therefore, there is an urgent need to develop a parameter debugging system that can be applied to a variety of models. The system developed in this paper can realize the parameter debugging and fault diagnosis of many kinds of vehicles, and has the characteristics of simple operation, good flexibility and high compatibility. The main content of this paper includes four parts: system design, hardware design, software design and real vehicle debugging. Firstly, the principle of parameter debugging and fault diagnosis system is analyzed theoretically. The setting of 10 important parameters in the gearbox and the corresponding method of fault diagnosis for the gearbox are put forward. In the design of hardware circuit, LPC2132 single chip microcomputer is used as the core processing chip, and matrix keyboard circuit is designed, which makes full use of the multi-channel 10-bit A / D UART module and the timing counter I2C module of the internal integration of LPC2132, and improves the integration degree of the circuit. Software program design is mainly to write C language program to complete the LCD 12864 LCD screen on various debugging and diagnosis function operation. It includes the initial setting of AMT parameters, the modification of parameters, the analysis and judgement of AMT faults in storage and transmission, and the display of related faults, etc. After debugging and running, the system realizes the expected function. AMT parameter debugging and fault diagnosis system, and completes the parameter debugging and fault diagnosis of various models. It has high reference significance and good application value in AMT parameter debugging and fault maintenance.
