Abstract

To reduce rear-end collision risks and improve traffic safety, a novel rear-end collision escape algorithm is proposed for intelligent vehicles supported by vehicular communication. Numerous research has been carried out on rear-end collision avoidance. Most of these studies focused on maintaining a safe front clearance of a vehicle while only few considered the vehicle’s rear clearance. However, an intelligent vehicle may be collided by a following vehicle due to wrong manoeuvres of an unskilled driver of the following vehicle. Hence, it is essential for an intelligent vehicle to maintain a safe rear clearance when there is potential for a rear-end collision caused by a following vehicle. In this study, a rear-end collision escape algorithm is proposed to prevent rear-end collisions by a following vehicle considering both straight and curved roads. A trajectory planning method is designed according to the motions of the considered intelligent vehicle and the corresponding adjacent vehicles. The successive linearization and the Model Predictive Control (MPC) algorithms are used to design a motion controller in the proposed algorithm. Simulations were performed to demonstrate the effectiveness of the proposed algorithm. The results show that the proposed algorithm is effective in preventing rear-end collisions caused by a following vehicle.

基于车载通信的智能车辆追尾逃生算法

为降低追尾碰撞风险，提高行车安全性，提出了一种基于车载通信支持的智能车辆追尾逃逸算法。在汽车追尾避碰方面进行了大量的研究。这些研究大多侧重于保持车辆的安全前方间隙，而很少考虑车辆的后方间隙。然而，智能车辆可能会由于跟随车辆的非熟练驾驶员的错误操作而与跟随车辆相撞。因此，当后面的车辆可能发生追尾碰撞时，智能车辆必须保持安全的后方间隙。在本研究中，提出了一种追尾逃逸算法，以防止直线和弯曲道路上的后续车辆追尾。根据所考虑的智能车辆及其相邻车辆的运动，设计了一种轨迹规划方法。该算法采用连续线性化和模型预测控制(MPC)算法设计运动控制器。仿真实验验证了该算法的有效性。实验结果表明，该算法能够有效地防止后续车辆的追尾。

期刊介绍： At present, transport is one of the key branches playing a crucial role in the development of economy. Reliable and properly organized transport services are required for a professional performance of industry, construction and agriculture. The public mood and efficiency of work also largely depend on the valuable functions of a carefully chosen transport system. A steady increase in transportation is accompanied by growing demands for a higher quality of transport services and optimum efficiency of transport performance. Currently, joint efforts taken by the transport experts and governing institutions of the country are required to develop and enhance the performance of the national transport system conducting theoretical and empirical research. TRANSPORT is an international peer-reviewed journal covering main aspects of transport and providing a source of information for the engineer and the applied scientist. The journal TRANSPORT publishes articles in the fields of: transport policy; fundamentals of the transport system; technology for carrying passengers and freight using road, railway, inland waterways, sea and air transport; technology for multimodal transportation and logistics; loading technology; roads, railways; airports, ports, transport terminals; traffic safety and environment protection; design, manufacture and exploitation of motor vehicles; pipeline transport; transport energetics; fuels, lubricants and maintenance materials; teamwork of customs and transport; transport information technologies; transport economics and management; transport standards; transport educology and history, etc.
