Expressway-based embedded integrated automatic driving controller

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.
