Ease of driving along lines which drivers assumed may be called "correctness of steering." The driving along lines causes meandering. To improve correctness of steering, this paper considers the natural frequency and amplitude of the meandering. First this paper introduces a driver model that employs driver's dead zoon of sense of visual and can describe this steady weaving. Secondly this dead zone is approximated to be a cubic function. Finally this paper formulates the weaving frequency and its amplitudes. The result shows the amplitude of lateral acceleration increases due to reduction of course tracking performance.
