论文摘要

现代车辆使用控制器区域网络(CAN)总线向传感器,执行器和电子控制单元(ECU)进行通信,该数据以差分信号传导运行。通过从CAN总线中吸收信息来开发负责执行自动驾驶汽车决策命令的自主ECU。解析决策命令的常规方式是运动计划,该计划使用路径跟踪算法来评估决策命令。这项研究重点是使用深度学习框架使用自动驾驶汽车的行为克隆和运动计划来设计强大的控制器。在本研究的第一部分中,我们探索了从路径跟踪算法到控制器的解析决策命令的管道,并使用行为克隆提出了基于神经网络的控制器($ n^2c $)。拟议的网络在接受从CAN总线获取的手动驾驶数据训练时,可以预测油门,制动和扭矩。通过将准确性与比例衍生综合(PID)控制器与路径跟踪算法(纯追求和基于模型预测性控制的Pathroter)进行比较,可以证明所提出方法的功效。这项研究的第二部分补充了$ n^2c $,其中端到端神经网络用于预测速度和转向角度,并以图像数据作为输入。实时和在Udacity数据集上评估了所提出的框架的性能,与最先进的方法相比,在以前的情况下显示出更好的度量分数和可靠的预测。

Modern vehicles communicate data to and from sensors, actuators, and electronic control units (ECUs) using Controller Area Network (CAN) bus, which operates on differential signaling. An autonomous ECU responsible for the execution of decision commands to an autonomous vehicle is developed by assimilating the information from the CAN bus. The conventional way of parsing the decision commands is motion planning, which uses a path tracking algorithm to evaluate the decision commands. This study focuses on designing a robust controller using behavioral cloning and motion planning of autonomous vehicle using a deep learning framework. In the first part of this study, we explore the pipeline of parsing decision commands from the path tracking algorithm to the controller and proposed a neural network-based controller ($N^2C$) using behavioral cloning. The proposed network predicts throttle, brake, and torque when trained with the manual driving data acquired from the CAN bus. The efficacy of the proposed method is demonstrated by comparing the accuracy with the Proportional-Derivative-Integral (PID) controller in conjunction with the path tracking algorithm (pure pursuit and model predictive control based path follower). The second part of this study complements $N^2C$, in which an end-to-end neural network for predicting the speed and steering angle is proposed with image data as an input. The performance of the proposed frameworks are evaluated in real-time and on the Udacity dataset, showing better metric scores in the former and reliable prediction in the later case when compared with the state-of-the-art methods.
