Automatic driving automobile control system and method and microcontroller

Abstract

The invention provides an automatic driving automobile control system and method and microcontroller. The microcontroller comprises a main processor, a coprocessor and a CAN controller. The CAN controller is connected with the coprocessor and the main processor in a communication way to receive a CAN message and forward the CAN message to the coprocessor. The coprocessor interrupts receiving of the CAN message and the I / O input signal forwarded by the CAN controller and analyzes the CAN message and the I / O input signal so as to obtain corresponding control information and transmit the control information to the main processor. The main processor processes the control information so as to obtain a corresponding control output instruction to be transmitted to a second automobile controller used for controlling acousto-optic performance, starting and electrical parking of the automatic driving automobile or transmitted to a second automobile controller used for controlling driving of the automatic driving automobile. The communication load between the upper computer system and the microcontroller can be reduced and the communication efficiency between the upper computer system and the microcontroller can be enhanced.

Description

technical field [0001] The invention relates to the technical field of automobiles, in particular to a control system, method and microcontroller of an automatic driving automobile. Background technique [0002] Driverless car technology is not mature enough at this stage, and there are still many limitations in actual operation. When the car is driving in driverless state, it can automatically detect changes in the driving environment to determine whether to return to the manual driving mode. There is no need to monitor the car's control system all the time. [0003] The patent with the patent publication number CN201387545 discloses a technical solution: an electric vehicle intelligent control device is designed, including an industrial control computer (hereinafter referred to as: industrial computer) and electronic circuit control. When the industrial computer passes CAN bus and CAN router at the same time When acting on the CAN bus in the car, the industrial computer i...

AI Technical Summary

Problems solved by technology

The technical solution disclosed in this patent has these deficiencies: although the car can collect data, there are many devices connected to the CAN bus on the car, and each industrial computer communicates with each device of the car through the CAN bus, resulting in a problem between the industrial computer and each device. The communication load between them is heavy and the communication cycle is long, which leads to a corresponding increase in the time spent on processing data by the industrial computer, and a longer control cycle for the car, which is not conducive to complex control such as unmanned driving and real-time control in dangerous situations
