汽车检测实验装置中车速信号的模拟研究

Simulation research of speed signal in automobile testing experimental device

根据施密特触发器能自行产生与车速信号相类似的矩形脉冲信号这一工作原理,开发出车速模拟信号触发装置,并将此装置用于LS430空气悬架及电动助力转向模拟测试系统。实验结果表明:该模拟信号触发装置触发的模拟信号,能够代替车速信号被系统所识别。

Conclusions show that the Multivibrator can generate a rectangular pulse signal that is similar to the speed signal by the research of Schmitt Trigger and Multivibrator.The speed analog signal triggering device is developed according to this working principle. Speed analog signal triggering device developed for The LS430 Air Suspension and Electric Power Steering Simulation. Tests shows that the analog signal triggered by the speed analogy signal triggering device can replace the speed signal and being identified.
