Abstract:
PURPOSE: A task management device using an array-type task scheduling table of a real-time operating system and a management method thereof are provided to comprise the task scheduling table that the operating system refers for a context switch as an array, thereby improving real-time performance of the operating system. CONSTITUTION: A memory(20) stores tasks by comprising a task scheduling table(21) which is fixed by using arrays in a constant area. When one task is executed in an operating system, a microprocessor(10) stores a current task in the task scheduling table by determining generation of a context switch and executes a next task by reading the same. A specification of each task is assigned to the task scheduling table.

Abstract:
PURPOSE: A TTCN-3(Testing and Test Control Notation Version 3) based AUTOSAR(AUTomotive Open System ARchitecture) software test automation system and a testing method thereof are provided to reduce the test time and efforts by immediately performing test based on a test automation environment, and checking the test result. CONSTITUTION: A software design information extractor(200) extracts the AUTOSAR software component design information from the AUTOSAR software component. The TTCN-3 test system(300) generates information which is necessary for the test of the AUTOSAR software component from the AUTOSAR software component design information, and transmits the information to a target system(400). The TTCN-3 test system receives the test result from the target system, and decides the suitability of the AUTOSAR software component.
Abstract:
PURPOSE: An exterior ECU(Electronic Control Unit) apparatus, a vehicle ECU extension method/apparatus, and a vehicle using the same are provided to provide additional services and improved performance by extending a vehicle ECU using the exterior ECU apparatus. CONSTITUTION: An ECU extension method for a vehicle(100) is as follows. An external ECU apparatus(110) mounted on an external ECU apparatus slot is recognized. The ECU ID(Identification) of the external ECU apparatus is read out. An embedded ECU(130) having the same ECU ID as the ECU ID is searched. The embedded ECU is replaced or supplemented with the external ECU apparatus.
Abstract:
PURPOSE: A window control device is provided to create driving force for lifting a window glass by maximizing magnetic force using a Halbach magnet array. CONSTITUTION: A window control device(100) comprises a window glass(120), a window frame(130), a linear guide rail(140), and a control system(150). The window glass opens and closes the window. The window frame is formed on the bottom surface of the window glass. The window frame supplies the drive force of the elevating movement of the window glass. The linear guide rail is formed to be adjacent to the window frame. The linear guide rail comprises an electromagnet part to which current is applied.
Abstract:
PURPOSE: A method for detecting traffic sign board and a system for executing the method are provided to control a background region and to reinforce the color contrast feature of an image. CONSTITUTION: A traffic sign board detection system inputs a sign board shape and a symbol shape of a traffic sign board installed on a real road into a database(S101). A color-to-feature map and an outline feature map are calculated in an input image(S105). A color tone contrast feature map and contour line feature map are used. An image enhanced map is generated using the color-to-feature map and outline feature map(S106). A traffic sign board within the input image is detected using the image enhanced map(S109).
