Microkernel kernel system applied in control software of vehicle air conditioning control panel products

Abstract

The invention discloses a microkernel kernel system applied in control software of vehicle air conditioning control panel products, which comprises the following steps of: (1) initializing; (2) converting tasks; (3) collecting user operation instructions: collecting the instructions sent out after the user operation; (4) displaying the system state: converting the command collected in the step (3) into system instructions and using a display device to represent each state of the system; (5) controlling logical calculation: calculating the states of each executing agency on the system instructions of the step (4) according to the logic of the air conditioning; (6) controlling drive output and controlling each executing mechanism; (7) implementing system services: providing CAN/LIN communication service; and (8) implementing basic system services: providing the basic services like a timer and ADC and the like. The logical change of the system structure leads the microkernel kernel system to have higher performance, consistency and robustness on multi-aspects like parallel development, testing and performances, and the like.

Description

technical field [0001] The invention relates to an automobile air-conditioning system, in particular to a microkernel system applied to control software of automobile air-conditioning control panel products. Background technique [0002] At present, the software structure applied in the control panel of automobile air conditioner is mainly divided into two categories: 1. Simple linear large loop ( figure 1 ); 2. Interrupt-based front-end and back-end systems ( figure 2 ). These two structures have drawbacks, such as long development cycle, poor software maintainability, heavy upgrade workload, and unstable parameters after upgrade. [0003] If a simple linear large loop or interrupt-based front-end and back-end systems are adopted, factors such as changes in control system functional requirements or changes in control logic will cause: a. Some functional modules need to be modified or b. New functional modules are added or c. Existing Software changes such as merging and...
