轿车侧方位安全出车的数学模型建立与求解

Establishment and Solution of Mathematical Model for Car Side Azimuth Safe Departure

在路右侧方位停车,剐蹭右车头是常发生的事,文章就轿车侧方位安全出车,以免剐蹭问题进行了讨论,把右车头以及四个轮中心位置视为一个平面四边形的顶点及边点,根据轿车右侧前、后轮相应点的运动特点,利用微元法,得到了该三点的运动规律,建立了离散数学模型,并以大众新桑塔纳轿车参数为例进行了计算,得到了安全出位避免与前车剐蹭的最小安全距离.由于不同型号轿车稍有差别,该建模方法和模拟对轿车依靠光学设备智能化导引具有一定的理论意义,模型简练便于智能计算.

When parking on the right side of the road,it is common to scratch the right front.This paper discusses the problem of safe driving on the side of the car to avoid scratching.The right front and the center of the four wheels are regarded as the vertices and edge points of a plane quadrilateral.According to the motion characteristics of the corresponding points of the front and rear wheels on the right side of the car,the motion law of the three points is obtained by using the microelement method,The discrete mathematical model is established,and the parameters of Volkswagen’s new Santana car are calculated,and the minimum safety distance to avoid scratching with the front car is obtained.Because different models of cars are slightly different,the modeling method and simulation have certain theoretical significance for the intelligent guidance of cars relying on optical equipment.The model is concise and convenient for intelligent calculation.
