Summary:The invention belongs to the field of electronics and provides a method and system for detecting vehicle frequent-lane-changing driving. The method includes the following steps that Z-axis angular speed is extracted and is Z-axis angular speed of three-axis angular speed obtained through a sensor in the process of vehicle driving; if Z-axis angular speed with the minus product of adjacent numerical values occurs in the Z-axis angular speed, the Z-axis angular speed within a specific time period is stored; if the number of Z-axis angular speed of which the numerical value is zero within the specific time period reaches a first threshold value, a vehicle is driven within the specific time period in a frequent-lane-changing mode. Through extracting values of the Z-axis angular speed, the values of the Z-axis angular speed with the minus values of the product of the adjacent Z-axis angular speed numerical values are stored, the stored Z-axis angular speed within the specific time period is analyzed, the number of
