Abstract
The disclosure provides a method and system for measuring steering angle error of a vehicle. The method includes the following steps: a rotating step is performed first, and the rotating step is to continuously rotate the steering wheel left and right between a left position relative to the center and a right position relative to the center when the vehicle is driving. A time-series change of the steering angle of the vehicle and a time-series change of a turning radius of the vehicle in the rotating step are obtained to calculate a response delay of the turning radius. Afterwards, the correlation expression of the turning radius is calculated, and the correlation expression corrects the response delay corresponding to the steering angle at multiple time points. Based on the correlation expression, the steering angle under the condition where the turning radius is 0 is defined as the steering angle error.
