Abstract:

For the economic and safety problems of vehicle curve adaptive cruise when the target in front is lost, a curve adaptive cruise strategy under multiple constraints is proposed in this paper. Firstly, the engine fuel consumption model and vehicle longitudinal dynamics model are established, considering the constraints of road curve curvature, and the optimal cruising speed of curves is planned based on the dynamic programming algorithm. Then, taking economy and safety as the target, the adaptive cruise longitudinal controller and transverse controller are designed by the PID algorithm and MPC algorithm, respectively. Finally, a joint simulation platform of CarSim and Simulink is built and simulation analysis is carried out. Based on ROS trolley, experimental verification is carried out, and the results show that the control method proposed in this paper has good economy and robustness.
