Abstract

The invention discloses a method and device for detecting the complexity of a vehicle driving scene, belongs to the technical field of automatic driving, and can be applied to an intelligent vehicle, a new energy vehicle and a networked vehicle, and the method comprises the steps: obtaining a target vehicle meeting a preset distance condition with the vehicle, and obtaining the driving speed of the vehicle and the driving speed of the target vehicle; determining the dynamic complexity of the driving scene where the vehicle is located based on the driving speed of the vehicle and the driving speed of the target vehicle; determining static information of each static factor in the current driving scene of the vehicle; based on the static information of each static factor, obtaining the static complexity of the driving scene where the vehicle is located; and based on the dynamic complexity and the static complexity, obtaining the comprehensive complexity of the driving scene where the vehicle is located. The comprehensive complexity determined by the method can reflect the actual complexity of the current driving scene of the vehicle more comprehensively.

Description

technical field [0001] The present application relates to the technical field of automatic driving, and in particular to a method and device for detecting the complexity of a vehicle driving scene. Background technique [0002] With the rapid development of self-driving cars, the traffic safety of self-driving cars has also attracted more attention. In highly complex driving scenarios, there may be certain dangers in autonomous driving of autonomous vehicles, requiring the driver to take over for manual driving. In this way, in order to be able to alert the driver to be ready to take over driving in highly complex driving scenarios, it is also crucial to determine the complexity of the driving scenario. [0003] At present, the following methods can usually be used to determine the complexity of a driving scene. The actual value of the static factors that affect the driving safety of the vehicle in the current driving scene of the vehicle and the driving speed of the vehic...
