HU Junping, ZENG Wuyang, LI Yongcheng. Algorithm of autonomous obstacle avoidance based on MPC[J]. 2019, (7): 146-149. DOI: 10.13873/j.1000-9787(2019)07-0146-04.
The behavior of vehicle obstacle avoidance in complicated road conditions will conflict with the behavior of obstacle avoidance. An algorithm for vehicle obstacle avoidance control based on MPC is proposed.Firstly
the vehicle is modeled by dynamics
and the tire nonlinear model is added
and then the discrete system is linearized. Integrate path tracking
vehicle stability
and avoidance obstacles
and coordinate behavioral conflicts by setting their priorities. Finally
the performance of the algorithm is verified by MATLAB simulation
and the feasibility of the algorithm dealing with complex road conditions is simulated using CarSim/MATLAB. Simulation results show that the control algorithm can coordinate the behavior conflict between stability and obstacle avoidance during the obstacle avoidance process
and can accurately represent the obstacle avoidance path of the vehicle
providing an important basis for the development of driverless and optimization of intelligent vehicle systems.
