A method for determining software errors in a virtualization-based integrated control system detects software errors for each partition (software of a vehicle controller) and recovers automatically. Thus, system reliability, which is an advantage of virtualization techniques, can be further enhanced, thereby providing an operator with stability, and software errors can be easily addressed by writing error information.
A method for determining an error in a virtualization-based integrated control system, wherein the system includes a virtualization-based integrated controller virtualizing a physical micro controller unit (MCU) to create a plurality of virtual MCUs, and software type controllers respectively operating on the virtual MCUs, the method comprising:

This application claims the benefit of priority to Korean Patent Application No. 10-2013-0059093, filed on May 24, 2013 in the Korean Intellectual Property Office, the disclosure of which is incorporated herein in its entirety by reference.
The present disclosure relates to a method for determining a software error in a virtualization-based integrated control system, and more particularly, to a method for automatically detecting an error occurring in partitioned software in a virtualization-based integrated control system and recovering the system to a normal state.
There are schemes for configuring an integrated controller. One scheme is to change a plurality of software logics (code change) suitable for one software platform in a hardware component. Another scheme is to partition a physical micro controller unit (MCU) into multiple virtual MCU using virtualization techniques without changing software platforms and software logic.
The above and other objects, features and advantages of the present disclosure will be more apparent from the following detailed description taken in conjunction with the accompanying drawings.
FIG. 1 is a view illustrating the configuration of a virtualization-based integrated control system according to an embodiment of the present disclosure.
FIG. 2 is a view illustrating the configuration of a virtualization-based integrated control system according to an embodiment of the present disclosure.
Hereinafter, embodiments of the present disclosure will be described in detail with reference to the accompanying drawings.
FIG. 1 is a view illustrating the configuration of a virtualization-based integrated control system according to an embodiment of the present disclosure.
As shown in FIG. 1, the virtualization-based integrated control system according to an embodiment of the present disclosure virtualizes a physical micro controller unit (MCU) 10 to include a virtualization platform for integrating controllers 20 (hereinafter referred to as virtualization-based integrated controller) that creates a first virtual MCU 30 and a second virtual MCU 40.
