基于轮轴速度传感器和加速度传感器的混合测速测距算法研究

Mixed Speed and Distance Ranging Algorithm Based on Odometer and Accelerometer

为避免单一轮轴速度传感器在测速测距中存在的问题,设计了一种基于轮轴速度传感器和加速度传感器的混合测速测距算法。经过实验室仿真环境测试,证明该算法能有效地检测出列车是否出现空转或滑行,并保证在列车发生空转或滑行后的测速测距误差能够满足车载控制器对测速测距精度的需求。

To overcome the problems happened in the single speed sensor, a mixed speed and distance ranging algorithm based on odometer and accelerometer is designed. Through laboratory simulation, the algorithm is capable to detect the train slip/slid effectively, and ensure the speed and distance errors be controlled within the accuracy requirements of the VOBC when train slipping/sliding occurs.
