A Preview Neuro-Fuzzy Controller Based on Deep Reinforcement Learning for Backing Up a Truck-Trailer Vehicle

Backing up truck-trailer vehicles is a required task in several industry sectors. Controllers that have been proposed to automate this process usually struggle when the vehicle is required to follow a nonlinear trajectory. This paper presents a neuro-fuzzy controller based on preview control and deep reinforcement learning for reverse parking truck-trailer vehicles. The controller consists of a deep neural network trained with reinforcement learning. A preview control signal is coupled into the trained controller to improve the control performance when tracking complex trajectories. Moreover, a fuzzy logic approach is used to avoid the jackknife state. Simulation results are presented to show that the controller is able to track circular and sinusoidal trajectories.
