An environment sensing system for a vehicle and a control method thereof

Abstract

An environment sensing system for a vehicle is disclosed, A forward millimeter wave radar mounted in front of the vehicle for obtaining front obstacle information is provided, and a rear millimeter wave radar mounted behind the vehicle for obtaining rear obstacle information, The front millimeter wave radar and the rear millimeter wave radar transmit signals to a processor through a CAN bus, the vehicle is provided with a camera for sensing the surrounding environment of the vehicle, the processor receives video data of each camera through an analog video input interface, and the processor outputs signals to an execution unit. A low-cost millimeter wave radar and a camera are use for realizing that perception of the surroundings of the intelligent vehicle, and the perception range of the surroundings of the intelligent vehicle include the real-time detection of targets in a region of 150 meters in front, adjacent lanes on the left and right sides and 50-60 meters behind the vehicle.

Description

technical field [0001] The invention relates to the technical field of smart cars, in particular to an environment perception system for smart cars under complex urban working conditions and an implementation method thereof. Background technique [0002] At present, in order to achieve intelligent assisted driving and automatic driving, the vehicle needs to detect the surrounding environment of the vehicle through sensors, often using vision sensors, millimeter-wave radar sensors and lidar sensors. Using lidar to realize the perception of the surrounding environment is expensive and difficult to achieve mass production. Using millimeter-wave radar, although it can detect targets in the front, rear and surrounding areas of the vehicle, it cannot realize the recognition and learning of the surrounding environment, and intelligent driving cannot be realized in an unstructured road environment. [0003] If the existing low-cost millimeter-wave radar and camera can be used compr...
