Problems solved by technology

[0003]However, most of the current self-driving vehicles are limited to driving on roads with a specific width, and the following two processing methods are used when the vehicle is driving on a narrow road : 1) Stop directly; 2) Reluctantly drive in a way with very uncertain safety
[0004]However, there are the following defects in the use of these two methods: 1) Although the first method is a safe way to deal with it, it needs It is not a reasonable way; 2) The second way is that the vehicle may be stuck by the road boundary or obstacles at any time, or there may be unexpected risks at any time

Abstract

The embodiment of the invention discloses a vehicle control method and device, electronic equipment and a medium, and belongs to the technical field of automatic driving. The vehicle control method comprises the steps of determining whether a vehicle is in a special scene or not in response to obtained positioning data of the vehicle and obtained sensing data of the vehicle; and if the vehicle is in the special scene, planning a target driving track of the vehicle passing through the special scene according to the sensing data of the vehicle. Through the vehicle control method and device, the electronic equipment and the medium of the technical schemes of the embodiment of the invention, safe and stable driving of an automatic driving vehicle on a special road can be accurately ensured.

Description

technical field [0001] The embodiments of the present application relate to the field of computer technology, in particular to the field of automatic driving technology, and specifically to a vehicle control method, device, electronic equipment, and medium. Background technique [0002] During the actual operation and use of self-driving vehicles, they will encounter various types of road environments, among which narrow roads are a very special road condition. Especially for closed or semi-closed scenarios, such as low-speed autonomous driving logistics vehicles in parks, industrial parks, campuses, large enterprise factories, etc. to perform tasks such as autonomous driving logistics distribution, autonomous driving commodity sales, autonomous driving security patrols, and autonomous driving road cleaning. in process. [0003] However, at present, the vast majority of self-driving vehicles are limited to driving on roads with a specific width, and the following two proces...
