Automatic driving system based on highway

Abstract

The invention relates to the technical field of automatic driving, in particular to an automatic driving system based on a highway. The automatic driving system comprises a sensor, a positioning module, a man-machine interaction module, an automatic driving controller and a vehicle executing module. A traditional laser radar is replaced with a monocular camera, a stereo camera, a forward-direction long distance millimeter microwave radar and four-corner middle distance millimeter microwave radars which are arranged behind an inside-vehicle rearview mirror, at the center of a vehicle front bumper and on the two sides of the front bumper and a rear front bumper correspondingly. Multiple kinds of information in traffic sign road information and obstruction information are collected separately. The whole automatic driving system of perception fusion, path planning, decision planning, controlling and the like is integrated into an embedded type controller to achieve automatic driving. Compared with a traditional automatic driving system adopting the laser radar, the cost is low, and integration is easy. Perception precision is improved greatly, the system is high in integration level and small in size, the size of the automatic driving system is reduced greatly, the power consumption of the system is lowered, and mass production is easy.

Description

technical field [0001] The invention relates to the technical field of automatic driving, in particular to a highway-based automatic driving system. Background technique [0002] Benefiting from the rapid progress of processor chips, deep learning technology and sensor technology, autonomous driving research has developed rapidly. Many OEMs, component suppliers, Internet companies and scientific research institutes have successively launched autonomous driving prototypes or autonomous driving systems, such as Google's driverless prototype, Baidu's Baizhi autonomous driving prototype, Nissan's drivepilot 1.0 automatic driving system, etc. The automatic driving system in the related technology has the following problems: the sensor uses lidar to perceive the driving environment, but at this stage the lidar is expensive, and it is not easy to integrate into the car body, affecting the shape; Integration of control and other systems into one controller requires multiple indust...

AI Technical Summary

Problems solved by technology

The automatic driving system in the related technology has the following problems: the sensor uses lidar to perceive the driving environment, but at this stage the lidar is expensive, and it is not easy to integrate into the car body, affecting the shape; Integration of control and other systems into one controller requires multiple industrial computers or multiple controllers to jointly complete the automatic driving control function. The system has a large size, high power consumption, and anti-vibration performance that does not meet the requirements of vehicle regulations. It is not easy to commercialize and quantify Produce
