The invention discloses a ramp confluence cooperative control method and system based on confluence time optimization. The method comprises the following steps: step 1, numbering according to a sequence that each intelligent network connection vehicle drives into a ramp confluence area; step 2, when the intelligent network connection vehicle drives into the ramp confluence area, calculating reference confluence time, earliest confluence time and actual confluence time of reaching a ramp entrance confluence position; step 3, each intelligent network connection vehicle broadcasts the identity number and the position information of the intelligent network connection vehicle and the actual confluence time when the intelligent network connection vehicle drives to the ramp confluence to other intelligent network connection vehicles through wireless communication; step 4, constructing an optimization problem of the actual confluence time of each intelligent network connection vehicle; step 5,updating the actual confluence time until convergence; and step 6, controlling the speed of the vehicle to pass through the ramp confluence at the actual confluence time obtained by convergence. Theintelligent network connection vehicle confluence time can be optimized, and the ramp confluence safety and traffic efficiency are improved.
