Interaction system and method for automatic driving controller and vehicle controller

Abstract

The invention relates to an interactive system of an automatic driving controller and a whole vehicle controller, comprising a whole vehicle switch, an automatic driving controller, a whole vehicle line control controller and a whole vehicle control actuator. The present invention involves steps: monitoring the vehicle control signal, L3 intervention information, L2 / L3 mode switching information, vehicle wire control feedback information, automatic driving controller status information and automatic driving mode; for example, the L2 / L3 mode switching information is L2 entry L3 information, the automatic driving mode is set to L3; if the L2 / L3 mode switching information is L3 back to L2 information, the automatic driving mode is set to L2; The switch forwards the vehicle control signal received by the first L2 control input interface; if the automatic driving mode is L3, the vehicle-by-wire command is determined by the automatic driving controller. The present invention fixes the main body for judging the automatic driving mode, standardizes the logic of the interactive state machine, and solves the problem of chaotic instruction receiving and execution.

Description

technical field [0001] The present invention relates to the technical field of automatic driving controllers, in particular to an interactive system and method for automatic driving controllers and vehicle controllers. Background technique [0002] At present, L3 autonomous driving is in its infancy in the field of commercial vehicles; an interaction strategy that can realize the interaction between the L3 automatic driving controller and the traditional vehicle controller to achieve the purpose of automatic driving, and has certain functional safety properties has not yet been formed. [0003] At present, there are many kinds of automatic driving control strategies adopted by major automatic driving manufacturers; among them, there are two mainstream technical solutions, and their respective technical characteristics and technical defects are as follows: [0004] 1. The automatic driving controller is connected to the original controller interface of the vehicle. In the L3 ...
