Embodiment Construction

[0049] The present invention will be further described below in conjunction with accompanying drawing:

[0050] The present invention provides a driving trajectory planning method. In order to realize the method, a sensing device mounted on the vehicle is required. The sensing device includes a forward-looking camera and a forward-facing long-distance millimeter-wave radar. The forward-looking camera can monitor the road surface in front of the vehicle The image is collected, and the forward long-distance millimeter-wave radar can effectively detect the center position and speed of the front target vehicle within its sensing range. The sensing device is mounted on the figure 2 On the vehicle 1 in the vehicle, it can detect in real time figure 2 The relevant information of the medium front target vehicles 2, 3 and 4 can also detect information such as lane lines in front of the vehicle. By performing image recognition on the image information collected by the front-view camer...

Abstract

The invention relates to a driving track planning method and device, an automobile, a controller and a computer readable storage medium, and aims to plan the driving track of the automobile in case ofa lane line loss scene. The method comprises the steps of when a lane line in front of a lane where a vehicle is located is lost, carrying out historical driving track fitting on all sensing vehiclesrecognized by a sensing device; determining a target vehicle which is not subjected to lane changing according to the historical driving track of each sensing vehicle; and planning the driving trackof the vehicle according to the historical driving track of each target vehicle.

Description

technical field [0001] The invention belongs to the field of automobile intelligence, and in particular relates to a driving trajectory planning method, device, automobile, controller and computer-readable storage medium. Background technique [0002] Autonomous driving technology is developing rapidly. At present, mainstream mass-produced L2 driving assistance systems are generally equipped with forward-looking cameras and forward-facing long-range millimeter-wave radars, which can realize lane-centered driving on structured roads. The current mainstream solution is to use the camera to detect lane line information to achieve centered driving. After the lane line is lost, the front target of the lane will be used as the following target for horizontal and vertical control. The system generally has the following problems. If there is no target in front of the lane, lateral control cannot be assisted by target information in the side lane; if the target in front of the lane c...
