摘　　要：为缩短汽车对障碍物的识别时间,实现汽车避障的即时控制,提出了一种基于大数据和即时建模的汽车避障控制新方法。应用即时建模技术,将一个包含大量不同情况下驾驶数据的数据库视为系统的数学模型,提取数据计算控制输入中的增益和控制时间,达到避让障碍物的目的。数值分析表明,该方法省去了复杂的数学模型,只需简单的算术运算和排序,即可实现实时控制,具有计算时间短的优点。与以前的控制方法相比,新的控制方法能更有效地避免各种障碍物。In order to shorten the recognition time of vehicle obstacles and realize the Just-in-Time control of vehicle obstacle avoidance,a new method of vehicle obstacle avoidance control based on large data and Just-in-Time modeling is proposed.Using the instant modeling technology,a database containing a large number of driving data in different situations is regarded as the mathematical model of the system,and the data is extracted to calculate the gain and control time in the control input,so as to avoid obstacles.The numerical analysis shows that the method can realize real-time control without complex mathematical model and only need simple arithmetic operation and sorting.It has the advantage of short calculation time.Compared with the previous control methods,the new control method can avoid various obstacles more effectively.
