The work aims to find the user interface design reasons behind the helplessness in the intelligent vehicle control APP, and improve the rationality of travel assistance. Based on the understanding of help-seeking problems in interface design, three reasons were found:complex activation mode, complex visual information, and low context matching. By the investigation of the static and dynamic scenarios in the vehicle travel and the understanding of user behavior, the idea of intelligent vehicle help-seeking interface interaction and visual design were proposed from the perspective of behavioral logic, the design opportunity of help-seeking service was also explored, and the method was proved through a case. The help-seeking interface design method was proposed from the perspective of simplifying activation mode, structuring visual information, rationalizing graphic meaning and platform collaboration. The help-seeking interface design should be based on the characteristics of static and dynamic contexts to optimize the logic of help-seeking, organize visual information and product’s helping strategy from the perspective of user behavior, to realize who will get helps if he asks and avoid the function becoming a mere formality.
