Embodiment Construction

[0017] The present invention provides a method for selecting a driving path fusion of an intelligent driving vehicle, which includes: a controller calculates multiple predicted trajectories of the vehicle from information obtained from multiple sensors, wherein: Judgment 1: When multiple predicted trajectories When the trajectory only includes: the predicted trajectory of the steering angle and the predicted trajectory of the steering wheel angle, judge and determine the first basic trajectory and identify the curve according to the vehicle speed of the vehicle; Judgment 2: When multiple predicted trajectories only include: the When the steering angle predicted trajectory, the steering wheel angle predicted trajectory and the effective static target predicted trajectory are used, the effective static target predicted trajectory is used to determine the second basic trajectory and identify the curve; Judgment 3: When there are effective In the predicted trajectory of the precedi...

Abstract

The invention provides an intelligent driving vehicle driving path fused selecting method. A controller calculates a plurality of predicted trajectories from a plurality of sensors and judges whethera steering angle predicted trajectory, a steering wheel angle predicted trajectory, an effective static object predicted trajectory and an effective front vehicle predicted trajectory exist in the plurality of predicted trajectories, and the above information is fused to predict a more accurate vehicle traveling trajectory, wherein the priority levels are the effective static object predicted trajectory (effective front vehicle predicted trajectory), the effective static object predicted trajectory, and the steering angle predicted trajectory and the steering wheel angle predicted trajectory.

Description

technical field [0001] The invention relates to a selection method for the fusion of driving paths of an intelligent driving vehicle. Background technique [0002] When realizing vehicle intelligent driving, the controller of the system needs to identify and predict the vehicle's driving trajectory to judge whether there is an obstacle on the vehicle's pre-traveling trajectory. When there are obstacles around the driving track, such as vehicles or pedestrians, the system needs to judge whether a dangerous scene will occur when the car is driving according to the pre-traveling track through the obstacles and the motion state of the vehicle. [0003] It is relatively easy to predict the vehicle trajectory in the straight road, but it is often difficult to accurately predict the curve, especially the scene where the straight road turns into a curve. [0004] Accurately predicting the vehicle's driving trajectory plays a vital role in the false alarm rate of the vehicle's intel...
