The invention relates to a jitter detection device and a jitter detection method based on a Hall sensor. The device comprises a first Hall element, a second Hall element, a digital processing unit and two same and symmetrical signal processing units, the first Hall element and the second Hall element are respectively used for detecting the magnetic field change of a Hall effect type rotating speed sensor in a vehicle-mounted system and correspondingly outputting a first detection voltage and a second detection voltage; the input ends of the two signal processing units are correspondingly connected with the output end of the first Hall element and the output end of the second Hall element respectively, and the two signal processing units are used for processing the first detection voltage and the second detection voltage to correspondingly obtain a first digital signal and a second digital signal; the input end of the digital processing unit is connected with the output ends of the two signal processing units, and the digital processing unit is used for judging whether the vehicle-mounted system is in a jitter environment or not according to the phase difference of the first digital signal and the second digital signal at different moments; according to the method, whether the vehicle-mounted application environment is in the jitter state or not can be effectively judged.

    本发明涉及一种基于霍尔传感器的抖动检测装置及检测方法,其装置包括第一霍尔元件、第二霍尔元件、数字处理单元以及两个相同且对称的信号处理单元;第一霍尔元件以及第二霍尔元件分别用于检测车载系统中霍尔效应式转速传感器的磁场变化,对应输出第一检测电压以及第二检测电压;两个信号处理单元的输入端分别对应连接第一霍尔元件的输出端及第二霍尔元件的输出端,用于处理第一检测电压以及第二检测电压对应得到第一数字信号以及第二数字信号;数字处理单元的输入端分别连接两个信号处理单元的输出端,用于根据第一数字信号与第二数字信号在不同时刻的相位差判断车载系统是否处于抖动环境;本发明能够有效地判断出车载应用环境是否处于抖动状态。
