A safety linear control model (SLCM) based on method is proposed for the low tolerance of collision autonomous vehicles in environment incomplete internet vehicles. On premise considering vehicle delay, local stability proved by Lyapunov linearization and transfer function method, it calculated that string stable when speed exceeds 2.6m/s. Finally, under periodic boundary condition, numerical simulation comparison traffic flow state three representative scenarios are carried out. The results show that, basis same collision-free, compared with Gipps model, SLC reduces start transient time 80%, variance preceding distance 40.28% average, 37.27% which improves rapidity stability, more compatible lane changing scenarios.
