The invention relates to a strong-robustness self-adaptive driving antiskid control method used for a hub motor driven electric vehicle and capable of improving acceleration comfort. Influence of tirerelaxation characteristics during design is fully considered, and a regional pole assignment algorithm is used to assign poles near a real axis to reduce longitudinal jitter of acceleration during intervention of a driving antiskid system; a segmented robust control method is adopted to ensure the robustness of a controller when the working condition changes, and a gain scheduling algorithm is used to ensure the adaptability of the controller at any vehicle speed; the anti-skid method provided by the invention has the advantages that the robustness is high, adaptability to working condition is high, the stability of anti-skid control during running at any vehicle speed with change of road adhesion and vertical load can be ensured, the smoothness requirement of the vehicle during intervention of driving anti-skid control is met, longitudinal oscillation of vehicle body acceleration is reduced, and the riding comfort during vehicle acceleration is improved.
