Complete-vehicle control method and complete-vehicle controller of intelligent vehicle

Abstract

The invention discloses a complete-vehicle control method and a complete-vehicle controller of an intelligent vehicle. The method includes the steps that after a BSP is initialized and a system is initialized, a main task of the system is created; after system parameters are initialized, unit sub-tasks are created in the main task of the system; according to the priorities of the unit sub-tasks, time slice round-robin scheduling is performed; a time slice comprises a preset mode and / or a user-defined mode. Different task priorities can be distributed among the unit sub-tasks of the vehicle according to the importance of events, time slice round-robin scheduling is adopted for circulation, operation time of all the tasks is reasonably distributed, the requirement for real-time performance is met, in addition, the multi-task performance can be used for integrating part of intelligent unit modules into the complete-vehicle controller, in this way, the cost of each unit module is lowered, space inside the vehicle is saved, and communication faults among the modules are reduced.

Description

technical field [0001] The invention relates to the field of smart cars, in particular to a vehicle control method and a vehicle controller for a smart car. Background technique [0002] With the country's strong support for the new energy industry and the rapid development of the new energy industry, many provinces and cities have opened up the electric vehicle market. Electric vehicles have entered a stage of vigorous development, and the number of users is increasing day by day. Electric vehicles will soon become one of the main means of transportation for people to travel, so we have to pay attention to the safety level of vehicle operation and the application of intelligence. The vehicle controller is the control core of electric vehicles, and the industry will have higher and higher requirements for the safety of vehicle controllers; at the same time, the demand for intelligence in the field of electric vehicles is becoming increasingly obvious, and various intelligent...

AI Technical Summary

Problems solved by technology

The vehicle controller is the control core of electric vehicles, and the industry will have higher and higher requirements for the safety of vehicle controllers; at the same time, the demand for intelligence in the field of electric vehicles is becoming increasingly obvious, and various intelligent modules are being developed. It is continuously applied to electric vehicles. If various modules are not well planned, it will not only waste hardware resources, but also affect the safety of vehicle operation.

[0003] At present, the vehicle controller system has developed to a certain extent, but most of them have only made some improvements in the control function, but the operation safety of the system has not attracted enough attention.
