摘要:

利用可靠的轨迹预测方法,可以大大提高车辆网络中的态势感知。更精确的态势感知反过来又会显著提高关键安全应用的性能,例如前向碰撞警告(FCW),以及协同自适应巡航控制(CACC)等舒适性应用。因此,车辆轨迹预测问题需要深入研究,以提出一个端到端的框架,具有足够的精度要求的安全应用程序的控制器。这个问题已经在文献中使用不同的方法来解决。然而,机器学习,这是一个有前途的和新兴的领域,具有显着的潜力,时间序列预测,还没有探索足够的这一目的。在本文中,一个两层的神经网络为基础的系统,预测未来的值的车辆参数,如速度,加速度和横摆角速度,在第一层,然后预测的二维的【形】,即纵向和横向,轨迹点的基础上,第一层的输出。所提出的框架的性能进行了评估,从安全试点模型部署(SPMD)数据集的现实切入的情况下,结果表明,在预测精度相比,运动学模型,这是占主导地位的汽车行业采用的模型有显着的改善。我们的系统评估的理想和非理想的通信环境进行了调查。对于非理想的情况下,估计步骤包括在参数预测块之前的框架中,以处理丢包或传感器故障的缺点,并以期望的频率重建车辆参数的时间序列。

英文摘要:

Situational awareness in vehicular networks could be substantially improved utilizing reliable trajectory prediction methods. More precise situational awareness, in turn, results in notably better performance of critical safety applications, such as Forward Collision Warning (FCW), as well as comfort applications like Cooperative Adaptive Cruise Control (CACC). Therefore, vehicle trajectory prediction problem needs to be deeply investigated in order to come up with an end to end framework with enough precision required by the safety applications' controllers. This problem has been tackled in the literature using different methods. However, machine learning, which is a promising and emerging field with remarkable potential for time series prediction, has not been explored enough for this purpose. In this paper, a two-layer neural network-based system is developed which predicts the future values of vehicle parameters, such as velocity, acceleration, and yaw rate, in the first layer and then predicts the two-dimensional, i.e. longitudinal and lateral, trajectory points based on the first layer's outputs. The performance of the proposed framework has been evaluated in realistic cut-in scenarios from Safety Pilot Model Deployment (SPMD) dataset and the results show a noticeable improvement in the prediction accuracy in comparison with the kinematics model which is the dominant employed model by the automotive industry. Both ideal and nonideal communication circumstances have been investigated for our system evaluation. For non-ideal case, an estimation step is included in the framework before the parameter prediction block to handle the drawbacks of packet drops or sensor failures and reconstruct the time series of vehicle parameters at a desirable frequency.
