基于十字路口交通流場景的自動駕駛客車速度控制

打開文本圖片集

摘 要：針對車輛在十字路口與對面車輛存在潛在的碰撞風險，提出一種基于估算速度的控制方法。搭建仿真環(huán)境進行多次測試，對測試數(shù)據(jù)進行單因素方差分析。結(jié)果表明：所提方法可以預(yù)測對面車輛的未來軌跡和碰撞時間，并優(yōu)化自車的行駛速度，從而有效降低了碰撞風險。

Speed Control of Self-driving Bus Based on Intersection Traffic Flow Scenario

Abstract：This paper proposes an estimation-based speed control method aiming at the potential vehicle collisions with the vehicle from the opposite at the intersection. A simulation environment was built and multiple tests were carried out. One-way analysis of variance was performed on the test data. The results show that the proposed method can predict the future trajectory and collision time of the opposite vehicle， optimize the driving speed of the vehicle and effectively reduce collision risk.
