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.
