摘要
用一套三轴霍尔元件MLX90316设计并制作了汽车油门控制系统.论述了该系统的原理与组成结构,研究了传感器的独立线性度、重复性和一致性.实验结果表明,本传感器使用水平磁通量为50 mT的圆盘形磁铁,磁铁与芯片的距离为5 mm,在磁铁转速为50～300 r/s时,传感器的独立线性度小于1.05％,同一传感器的重复性相差0.02％,同批次传感器的一致性相差小于0.04％.
An automobile accelerator pedal system is designed by using a set of three axis Holzer element MLX90316.This paper describes the sensor＇s principle and structure,and researches its independent linearity,repeatability and consistency.The result shows that the sensor uses a disk-shaped magnet with the horizontal flux is 50 mT,and the distance between magnet and chip is 5 mm,when the magnet＇s rotating speed is 50～300 r/s,the sensor independent linearity is less than 1.05％,the D-value of the same sensor＇s repeatability is 0.02％,and the D-value of the same batch of sensor＇s consistency is less than 0.04％.
