The invention discloses a networked vehicle queue collaborative optimization safety control method and a networked vehicle queue collaborative optimization safety control system. Firstly, a leading vehicle and following vehicle queue system model is established, and vehicle state information is collected through a sensor; a distributed communication time delay elastic observer is designed to estimate the state of the pilot vehicle for the abnormity possibly existing in the inter-vehicle communication link. And the system makes a difference between the state of the following vehicle and the real state of the pilot vehicle or the state of the observer according to a communication link state judgment result, and an error system is constructed. Then, based on a value function, a Hamiltonian and an HJB equation are derived, and an optimal control law is solved. And finally, an evaluation and execution neural network in reinforcement learning is utilized to respectively approach the value function and the control law, and an optimized optimal control law is obtained through iterative calculation and is output to the following vehicle. According to the method, multi-vehicle-queue collaborative optimization control is realized, and the stability and robustness of the system under hostile attacks and abnormal communication are effectively improved.
