Problems solved by technology

[0004] However, these specific environmental perception information are generally set in advance, such as lane line offset and angle, vehicle distance and speed, etc., and cannot fully reflect the driving environment of the vehicle in a complex road environment. For example, road Uncommon obstacles, etc. may appear in the environment, which will cause the failure of the vehicle control subsystem
In addition, the traditional distributed processing method determines that the perception and driving methods of the automatic driving system cannot learn from the experience of excellent human drivers, and cannot achieve anthropomorphic automatic driving.

Embodiment Construction

[0034] The invention proposes a method for automatic driving of automobiles. The method utilizes the collected environmental perception information to establish a driving environment risk field, and according to the driving environment risk field and the driver's operation training deep learning model, the automatic driving of the vehicle can be realized, and the automatic driving of the vehicle can be reduced. The training difficulty of the driving model (model for short).

[0035] figure 1 It is a schematic flow chart of an embodiment of the automobile automatic driving method of the present invention. Such as figure 1 As shown, the method includes the following steps:

[0036] Step S102, establishing a vehicle automatic driving database according to the collected environment perception information and driver operation information, and dividing the vehicle automatic driving database into a training set and a test set to form samples. The training set is used to train the ...

Abstract

The invention discloses a vehicle automatic driving method and device, and relates to the technical field of vehicle intelligent control. The present invention establishes a risk model of the vehicle driving environment based on the field theory, thereby using the driving environment risk field to comprehensively reflect the vehicle's driving environment, which is beneficial to realizing automatic driving in different road environments. And the vehicle automatic driving model is trained based on the driving environment risk field and driver operations to learn from the experience of excellent human drivers and achieve anthropomorphic automatic driving.

Description

technical field [0001] The invention relates to the technical field of vehicle intelligent control, in particular to a method and device for automatic driving of a vehicle. Background technique [0002] In recent years, automotive driving assistance systems such as adaptive cruise control and lane keeping systems have developed rapidly, improving road traffic safety. [0003] People are currently working on autonomous driving technology for cars. One of them is based on the distributed processing method to realize the automatic driving technology of the car. This technology divides a large system into multiple subsystems, and each subsystem has clear semantic information. For example, the automatic driving system is divided into subsystems such as vision-based lane line recognition, radar-based vehicle recognition, pedestrian detection, and vehicle control. Each of these subsystems is responsible for one or more defined tasks. For example, different subsystems responsible...
