The car autonomous navigation system has been a hot topic in path planning. This paper focuses on control strategy design for car autonomous navigation with obstacles avoidance by using adaptive dynamic programming (ADP) approach. First, the method for car observing the environment in simulation process is introduced. Second, a continuous reward/punishmen signal for car autonomous learning the control strategy is proposed. Third, the different simulation environment with different obstacles' states are established by virtual reality (VR) technology. The simulation results show that the ADP approach provides the suitable reliability and stability for control strategy design on autonomous navigation problem.
