The embodiment of the invention provides a car following position correction method. The method comprises the steps that image information of a front car is acquired; obtaining distance information between the front vehicle and the current vehicle; determining the current size information of the front vehicle based on the image information of the front vehicle and the distance information between the front vehicle and the current vehicle; based on the current size information of the preceding vehicle, vehicle following position correction information of the current vehicle is determined through a three-dimensional flow field simulation model, and the three-dimensional flow field simulation model is determined based on the initial size information of the preceding vehicle. The actual size of the front vehicle is determined by acquiring the image information of the front vehicle and the distance between the front vehicle and the current vehicle, the three-dimensional flow field simulation model of the front vehicle is determined according to the initial size of the front vehicle, and the vehicle following position of the current vehicle is corrected according to the actual size of the front vehicle. And the vehicle following position is corrected, the current vehicle is controlled to run in the trailing vortex negative pressure area of the front vehicle, and the economical efficiency of fuel is improved.
本申请实施例提供了一种跟车位置修正的方法,包括:获取前车的图像信息;获取所述前车与当前车辆的距离信息;基于所述前车的图像信息和所述前车与当前车辆的距离信息,确定所述前车的当前尺寸信息;基于所述前车的当前尺寸信息通过三维流场仿真模型,确定所述当前车辆的跟车位置修正信息,所述三维流场仿真模型是基于所述前车的初始尺寸信息确定的。通过获取前车的图像信息和前车与当前车辆的距离,确定前车的实际尺寸,根据前车的初始尺寸确定前车的三维流场仿真模型,根据前车的实际尺寸对当前车辆的跟车位置进行修正,可以在车身周围存在空气来流的情况下,对跟车位置进行修正,控制当前车辆在前车的尾涡负压区内行驶,提高燃料的经济性。
