The invention provides a layered rolling optimization control method to solve the confluence control problem of intelligent network connection vehicles on an expressway entrance ramp under a mixed traffic condition. Firstly, a nonlinear vehicle longitudinal dynamics model is established, and a multi-vehicle cooperative confluence problem including vehicle power constraint and inter-vehicle safety distance constraint is constructed. A hierarchical cooperative confluence control architecture with efficient and energy-saving traffic as a target is provided, an upper layer solves an unconstrained optimal control problem based on a minimum principle to plan a flexible confluence point, and a lower layer designs and controls a Lyapunov function and a control barrier function by using the flexible confluence point provided by the upper layer. And reconstructing a target and a constraint expression form of an optimization problem, converting a multi-security constraint optimal control problem into a quadratic programming problem, and obtaining an optimal control law to realize security confluence. According to the entrance ramp confluence control method provided by the invention, various strict safety constraints can be met, and meanwhile, the vehicle driving performance and the traffic overall performance in a mixed traffic environment are optimized.
