Problems solved by technology

However, the performance of sensors such as cameras is limited, resulting in unstable lane recognition and low accuracy. It is necessary to introduce a large number of filters and estimation algorithms to make lane recognition more accurate, and the recognition accuracy is seriously reduced in low-speed, complex intersections, bad weather and other scenarios.
In order to achieve a higher level of intelligent driving vehicles, such as intelligent driving vehicles at L4 and L5 levels, the existing solutions need to be improved in terms of target confidence, reliability and computing power

Embodiment

[0057]When the vehicle is driving automatically, in different driving situations, it may be necessary to select the corresponding target vehicle for vehicle control. For example, when avoiding obstacles, it is necessary to select the target vehicle to avoid; and when following, it is necessary to select the target vehicle to follow. The selection of the target vehicle can provide a reference for the automatic driving of the self-driving car under different driving conditions, so as to realize the corresponding function.

[0058] See figure 1 , the embodiment of the present invention provides a target vehicle screening method. like figure 1 As shown, it is a flow chart of a target vehicle screening method, and the target vehicle screening method includes:

[0059] S100: Obtain a predicted driving trajectory of the self-vehicle within a preset time period.

[0060] During specific implementation, the predicted driving trajectory of the self-vehicle within a preset time can b...

Abstract

The invention discloses a target vehicle screening method. The target vehicle screening method includes: acquiring a predicted driving trajectory of a self-vehicle within a preset time period; determining the target driving trajectory of the self-vehicle according to the predicted driving trajectory and an electronic map ; The electronic map includes roadbed information, and the roadbed information is the static road surface facility condition of the driving section; obtain the current driving behavior of the self-vehicle; determine the current driving behavior of the self-vehicle according to the current driving behavior and the target driving track. target screening area; acquiring vehicles to be screened in the target screening area; selecting target vehicles from the vehicles to be screened. The invention also discloses a target vehicle screening device, equipment and storage medium. By adopting the present invention, it is not affected by factors such as weather and light detection distance, and the confidence is higher; the determination of the target screening area can be more in line with the current driving situation, and a reliable target vehicle can be selected for subsequent control.

Description

technical field [0001] The present invention relates to the technical field of automatic driving, and in particular, to a target vehicle screening method, device, equipment and storage medium. Background technique [0002] Intelligent driving or unmanned vehicles are attracting more and more attention. Major OEMs and technology Internet companies are actively investing a lot of manpower and material resources in research and development of intelligent driving, hoping to realize the mass production of intelligent driving vehicles as soon as possible. For the level of intelligent driving, it is generally divided into L0-L5 level. Among them, the L0 level is completely controlled by the driver, and the vehicle is only responsible for executing commands; the L1 level and L2 level are to assist the driver to control the vehicle, the driver needs to monitor the driving environment and be ready to take over at any time, the corresponding functions such as ACC, LKA; The L3 level be...
