Multi-mode Adaptive Cruise Control Strategy Considering Urban Traffic Environment
A multi-mode adaptive cruise control strategy is proposed to adapt to urban traffic environment.In the upper controller,six mode strategies are designed,which includes constant speed cruising,steady state following,approach/lane change,strong acceleration,strong deceleration and collision avoidance.The transition zone between throttle controller and brake controller is designed by PID control and lookup table method in the lower controller.The simulation results show that the upper controller can select the appropriate driving mode under complex working conditions,while the lower controller can meet the expected requirements of downhill/uphill acceleration control,which is in line with the characteristics of the vehicle drive system and can be applied to the real vehicle driving assistance system for the improvement of vehicle driving safety.
