Vehicle surrounding sensing system

Abstract

The invention discloses a vehicle surrounding sensing system. The vehicle surrounding sensing system is provided with a sensing mechanism which is installed on a vehicle body and collects vehicle surroundings. The sensing mechanism outputs a sensing signal to a controlling unit. The controlling unit is in communication with a vehicle ECU. The sensing mechanism comprises a 77 GHz millimeter wave radar, two 79 GHz millimeter wave radars, two 24 GHz millimeter wave radars, 16 ultrasonic radars, a trinocular camera, a monocular camera, a V 21 module and a navigation positioning system. The vehicle surrounding sensing system has the advantages of being simple in mode, low in cost and stable and reliable in performance, the system can sense the vehicle surroundings in real time, whether a vehicle driving route involves safety driving vehicles, pedestrians and other obstruction goals or not is identified, meanwhile, detailed information such as distances, speeds, positions, categories of the goals can be supplied to a data processing and decision controlling unit, so that safe, reliable and automatic running of an automatic driving vehicle in a road is guaranteed very well.

Description

technical field [0001] The invention relates to the field of intelligent vehicles, in particular to an environment perception technology applied to automatic driving vehicles. Background technique [0002] Autonomous driving technology has been developed for many years. Domestic companies including Baidu and various scientific research institutes have demonstrated their own driverless vehicles on various occasions, but the solutions all have one similarity in that they use multiple expensive lidar sensors. , leading to the additional configuration of sensors for self-driving vehicles to realize the self-driving function, which is several times more expensive than the vehicle itself, and it is far from mass production in terms of cost. In addition, some sensor environmental indicators do not meet vehicle regulations. This solution proposes a low-cost self-driving vehicle environment perception solution that does not use expensive and unqualified laser radars, but only uses c...
