Embodiment Construction

[0020] The present invention is described in further detail below by specific embodiments:

[0021] like figure 1 As shown in the figure, the purpose of the present invention is to provide an embedded integrated automatic driving environment controller for the special working conditions of expressways or similar scenes with distinct structural characteristics, relatively few traffic participants, and relatively simple traffic conditions, so as to realize self-adaptation Automatic driving functions such as cruise, lane keeping, autonomous lane change, autonomous overtaking, autonomous acceleration, emergency braking and automatic pullover.

[0022] The invention includes five major parts: an automatic driving perception unit, a vehicle vertical and horizontal motion control module, an abnormality processing module, a driving mode switching control module and a human-computer interaction control module. The autonomous driving perception module includes multi-sensor information ...

Abstract

The present invention belongs to the automatic driving technical field and relates to an expressway-based embedded integrated automatic driving controller. The expressway-based embedded integrated automatic driving controller comprises an automatic driving sensing unit, a vehicle vertical and horizontal action control module, a driving mode switching control module and a human-computer interaction control module which are all integrated on a programmable gate array; the programmable gate array comprises at least a data transmission interface, a control signal transmission interface and a human-computer interaction interface, wherein the data transmission interface carries out data interaction with an environment sensor and a vehicle speed sensor, the control signal transmission interface can transmit control instructions to an execution unit, and the human-computer interaction interface transmits signals to a human-computer interaction system. A whole set of automatic driving system with functions such as sensing integration, path planning, decision planning and control is integrated into an embedded controller, so that the expressway-based embedded integrated automatic driving controller can be realized, and automatic driving functions such as adaptive navigation, lane keeping, autonomous lane changing, autonomous overtaking, autonomous acceleration, emergency braking and automatic pull over can be realized, and the size of the automatic driving system can be greatly decreased, and the power consumption of the system is decreased. The controller is easy to realize mass production.

Description

technical field [0001] The invention relates to the technical field of automatic driving, in particular to a highway-based embedded integrated automatic driving controller. 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, parts 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, and Nissan’s drivepilot. 1.0 automatic driving system, etc. The automatic driving controller in related technologies does not integrate perception fusion, path planning, decision control and other systems into one controller, and requires multiple industrial computers or multiple controllers to complete the automatic driving control function together. The power consumption ...
