The invention relates to the technical field of automobiles, in particular to an automobile steering auxiliary system. The system comprises a distance detection module, a duration module, a processing module and an alarm module. The distance detection module is arranged on the side of the body; the distance detection module is used for detecting the distance between the vehicle body and an obstacle in real time to obtain a distance parameter; the duration module is used for starting timing to obtain a duration parameter when the distance detection module detects the obstacle; the processing module is used for calculating the relative speed according to the distance parameter and the duration parameter; the processing module is used for calculating theoretical impact duration according to the distance parameter and the relative speed; the processing module is used for comparing the theoretical impact duration with the reaction duration and obtaining a comparison result; and the alarm module is used for sending out corresponding alarm information according to the comparison result. A detection mode in the prior art is not suitable for dynamic obstacles. Compared with the prior art, by comparing the theoretical impact duration with the reaction duration, dynamic obstacles can be effectively detected and alarmed.
