Abstract: The diversification of students is the inevitable trend after the enrollment expansion of higher vocational colleges. The traditional unified training method obviously can not meet the requirements. The teaching method should be changed according to the change of learning situation to ensure the quality of talent training. Under this background, combined with the characteristics of automobile professional courses, a new layered teaching mode based on hybrid learning is proposed, and the motor and control system maintenance course is taken as an example for practical research. The specific realization process is expounded from five aspects: students' stratification, teaching objectives stratification, online teaching design, offline teaching design and examination and evaluation stratification. The practice results show that the hybrid layered teaching has well mobilized the learning enthusiasm of students at all levels and achieved good teaching results.
