摘要
自动变速器作为汽车的重要传动部件之一,它的质量和运行状况直接影响着汽车整车的安全及性能。该文利用虚拟仪器模拟了汽车自动变速器的转速信号、汽车车速信号和冷却液温度信号,利用LabVIEW软件搭建了虚拟监测系统。监测在不同挡位时各个信号之间的变化,实现了数据的显示、处理、报警、数据回放等功能。测试结果证明,计算机结合虚拟平台构建的监测系统,可以实时监测汽车变速器的各项指标,满足了设计要求。
Automatic transmission as one of the important transmission parts of the automobile,its quality and performance will directly affect the safety and performance of the vehicle.The virtual instrument is used to simulate the speed signal,the vehicle speed signal and the coolant temperature signal of the automatic transmission.And virtual monitoring system is built by LabVIEW software.It monitored the change between the signals at different gears and achieved the function of data display,processing,alarm,data playback and so on.Test results show that automatic transmission operation monitoring system can real-time monitoring the indicators of auto transmission,meet the design requirements.
