Speed limit fusion method and system based on multiple sensors, vehicle and storage medium

Abstract

The invention discloses a speed limit fusion method and system based on multiple sensors, a vehicle and a storage medium. The speed limit fusion method comprises the steps of acquiring front-view camera speed limit information and ADAS map speed limit information; fusing the front-view camera speed limiting information and the ADAS map speed limiting information, specifically, when the front-viewcamera is not available, outputting the ADAS map speed limiting information; when the ADAS map is not available, outputting camera speed limit information; when both the ADAS map and the forward-looking camera are available, fusing according to the following strategies: if the type of the speed limiting information output by the ADAS map is the electronic eye, outputting the speed limiting value and distance of the electronic eye; if the type of the speed limiting information output by the ADAS map is a non-electronic eye, and the speed limiting information of the ADAS map and the speed limiting information of the camera are detected at the same time in non-expressway and urban expressway, outputting the speed limiting value and distance of the ADAS map; and when the ADAS map and the front-view camera are not available, considering that the function is invalid. The output speed limit value is more accurate.

Description

technical field [0001] The invention belongs to the technical field of automobile assembly, and in particular relates to a multi-sensor-based speed limit fusion method, system, vehicle and storage medium. Background technique [0002] With economic development, the transportation system has become the lifeblood and hub of travel activities. People's increasing living standards have higher and higher requirements for travel efficiency and convenience. In recent years, the development of smart cars has attracted more and more attention and attention. Through multiple sensors, the information around the vehicle's location is sensed, and the corresponding multiple sensor information is integrated to make analysis and judgment, so as to reduce the danger in the driving process. performance and improve driving comfort. [0003] Intelligent speed limit is to use the forward-looking camera or map to send the identified road traffic Peugeot speed limit information, and adjust the c...
