Embodiment Construction

[0071] It should be understood that the specific embodiments described here are only used to explain the present invention, not to limit the present invention.

[0072] refer to figure 1 , an embodiment of a vehicle control method for a smart car of the present invention is proposed. The vehicle control method may include:

[0073] Step S10, after the BSP board support package (Board Support Package) initialization and system initialization, create a system main task;

[0074] Step S11, after the system parameters are initialized, create unit subtasks in the system main task;

[0075] Step S12 , perform time slice round-robin scheduling according to the priority of unit subtasks; the time slice includes a preset method and / or a user-defined method.

[0076] The smart car system of this embodiment mainly includes: a hardware circuit (BSP) subunit, an operation control subunit, a battery management subunit, a voice recognition subunit, an automatic steering subunit, and an au...

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...
