为提高汽车在山区公路上驾驶的安全性,防止因驾驶员对不和谐线形的疏忽而造成的交通事故,利用采集到的各种驾驶信息和车辆行驶信息对公路线形进行判断,从而实现对驾驶员的预警。基于山区公路线形判断的主动安全技术,首次被提出。采用矩阵论的思想,将各种不和谐线形定义为状态矩阵,将各种驾驶信息和车辆行驶信息定义为信号矩阵。根据信号矩阵对判断不和谐线形的贡献值不同,建立初始权重矩阵。然后,通过Matlab软件进行迭代仿真,从初始权重矩阵过渡到最终的权重矩阵,该权重矩阵可以作为常量直接使用。用给定线形对最终权重矩阵进行检验,其结果表明:使用该权重矩阵对线形进行判断,得到的结果与给定线形一致。
In order to improve the safety of driving a car on a mountain road and prevent a traffic accident caused by the inadvertent driver’s dissonance, the road shape is judged by using the collected driving information and the driving information of the car, so as to achieve the goal of driving Early warning. For the first time, active safety technology based on line shape judgment in mountainous areas was proposed. Using matrix theory, various dissonance lines are defined as state matrices, and various driving information and vehicle driving information are defined as signal matrices. According to the signal matrix to determine the dissonance of the contribution of different linear, the establishment of the initial weight matrix. Then, through iterative simulation of Matlab software, the initial weight matrix transition to the final weight matrix, the weight matrix can be used directly as a constant. The final weight matrix is tested with the given linearity. The results show that the linearity is judged by the weight matrix, and the result is consistent with the given linearity.
