摘要
为使汽车驾驶模拟器实现实车运动状态及结构特征仿真,设计了基于单片机的数据采集系统和仪表控制系统;首先,数据采集系统采用ATmega2560单片机对模数信号进行采集与处理;其次,仪表控制系统采用Arduino UNO R3开发板、步进电机扩展板和28BYJ-48步进电机实现车速表和转速表的实时显示;然后,以数据帧的形式完成串口通信,基于VS2010使主控计算机同时完成读写功能;最后,在汽车驾驶模拟器上进行实验并对方向盘信号的处理过程进行优化;实验结果表明:系统能够完成行业标准(JT/T 378-2014)对汽车培训驾驶模拟器的功能要求,且可以实时传送操作状态,动作延迟低,数据传输稳定,且成本较低,具有一定的实用性。
In order to realize the simulation of vehicle’s state of motion and structure characteristics,the data acquisition system and instrument control system based on MCU are designed.Firstly,the data acquisition system uses ATmega2560 to collect and process the analog signal.Next,the instrument control system uses Arduino UNO R3 board,stepper motor expansion board and 28BYJ-48 stepper motor to realize real-time display of speedometer and engine tachometer.Then,serial communication is accomplished in the form of data frames.Based on VS2010,the main control computer can read and write at the same time.Finally,the experiment is carried out on the car driving simulator and optimize the process of steering wheel signal processing.The experimental results show that the system can fulfill the functional requirements of JT/T 378-2014 for driving simulator of automobile training,transmit operation status in real time,low delay,stable data transmission and low cost,so it has certain practicability.
