This invention is an extension adaptive lane keeping control method with variable vehicle speed, which is composed of the following steps: S1, establishing a three-degree-of-freedom dynamic model and a preview deviation expression; S2, performing the lane line fitting equation; S3, designing the upper layer ISTE extension controller; including: S3.1, establishing the control index (ISTE) extension sets; S3.2, dividing the control index (ISTE) domain boundaries; S3.3, calculating the control index (ISTE) association function; S3.4, establishing the upper layer extension controller decision; S4, designing the lower layer speed extension controller; S5, designing the lower layer deviation tracking extension controller; including: S5.1, extracting the lower layer deviation tracking extension feature quantity and dividing domain boundaries; S5.2, designing the lower layer extension controller correlation function; S5.3, performing the lower layer measurement mode identification; S5.4, When the front wheel angle of lower layer controller outputs is calculated according to the measurement mode. This invention realizes the adaptive variation of the control coefficient of the extension controller and the boundary range of the constraint domain according to the tracking deviation precision, the speed variation, and the expert knowledge base.
