Problems solved by technology

For roads without lane lines and roads with unrecognizable lane lines, potentially dangerous targets cannot be determined, and thus real dangerous targets cannot be further screened out from multiple potentially dangerous targets

Embodiment Construction

[0069] Generally speaking, the identification of dangerous targets includes two steps: the first step is to identify potentially dangerous targets from the targets around the vehicle: the on-board sensors perceive the targets around the vehicle as comprehensively as possible, and pass the relevant information to the target screening module. The second step is to screen out dangerous targets from potentially dangerous targets: the target screening module selects the correct dangerous targets from potentially dangerous targets. The dangerous objects corresponding to different application types may be different. For example, the dangerous object corresponding to AEB is the braking object, and the object corresponding to the Adaptive Cruise Control (ACC) is the following object. Wherein, regarding the first step, traditional methods include the following methods 1 and 2:

[0070] Method 1. Potentially dangerous targets are acquired based on lane lines.

[0071] For example, pleas...

Abstract

The embodiment of the invention provides an automatic driving dangerous target determination method and device. The method comprises the steps of determining a dangerous region and a track prediction period through the motion state data of a first vehicle, predicting the motion track of a target around the first vehicle in a track prediction period, and determining whether the target is a potential dangerous target by using the motion track and the dangerous region. The potential dangerous target is determined from the targets around the first vehicle according to the kinetic parameters of the first vehicle, and dependence on lane lines is avoided. Meanwhile, false triggering and missed triggering of safety measures are avoided, and the driving safety and comfort of automatic driving are both considered.

Description

technical field [0001] The present application relates to the technical field of automatic driving, and in particular to a method and device for determining a dangerous target in automatic driving. Background technique [0002] With the rapid development of the fifth-generation (5th-Generation, 5G) communication technology and Internet of Vehicles technology, autonomous driving technology has become a research hotspot. In autonomous driving technology, detecting objects on the road, such as vehicles and pedestrians, is a prerequisite for making driving behavior decisions. [0003] In the process of automatic driving, not all objects around the vehicle will affect driving safety, but only objects that meet certain conditions may affect driving safety, for example, vehicles, pedestrians, etc. within the two lanes on both sides of the vehicle , and objects such as vehicles and pedestrians whose volumes are mostly within the two lane lines. These targets that may affect drivin...
