汽车驾驶模拟器车速里程表和发动机转速表模拟系统的研究

介绍了汽车驾驶模拟器中车速里程表和发动机转速表模拟系统的建立过程及方法．在这个系统中，首先利用D／A转换板卡，采用Visual C＋＋ 6．0编程技术将动力学模型中的发动机转速和车速两个数字量进行D／A转换和处理成电压量．然后分别将车速的电压量通过变频器来控制电机的转速。通过电机来驱动车速表；将发动机转速的电压量转换成脉冲来驱动发动机转速表，以此来建立汽车驾驶模拟器车速里程表和发动机转速表模拟系统．

Simulation for Vehicle and Engine Speed Watches of Driving Simulator

The process and approaches in establishing a simulation system for vehicle speed watch and engine speed watch of driving simulator are introduced in this paper. In this system, the speed data of engine and vehicle derived from the vehicle model is converted into analog data (voltage data) through D/A convert board and Visual C~(++)6.0 programming. It simulates the speed of soft axle through the transducer electromotor and the pulse ignition system of engine through V/F electro circuit, which control the speed watch of vehicle and engine respectively. Thus, the simulation for vehicle and engine speed watches of driving simulator is established.
