    摘要： A method performed by a fault management device including a microcontroller is provided. The method includes receiving fault information from a controller connected to the fault management device. The method also includes incrementing a first counter in response to receiving the fault information. The method additionally includes incrementing a second counter and initializing the first counter, when the first counter exceeds a first reference value. The method further includes incrementing a third counter and initializing the second counter, when the second counter exceeds a second reference value. When the fault management device does not receive the fault information for a first reference time or more, the first counter decrements.

    摘要： A microcontroller performs a control function. The microcontroller comprises: a memory management unit (MMU) performing a soft reset process by initializing remaining areas excluding a working page area of a memory managed by the memory management unit of the microcontroller; a communication module maintaining a communication connection prior to the soft reset process as it is even after the soft reset process; and a microprocessor initialized according to the soft reset process.

    摘要： A method performed by an electronic control unit (ECU) includes: manipulating a boot area of an ECU so that the boot area is in an abnormal state; entering a boot strap loader (BSL) area of the ECU in response to detecting that the boot area is in an abnormal state upon resetting the ECU; determining whether to perform reprogramming of the boot area based on ROM identification information stored in the BSL area; and reprogramming the boot area when it is determined to perform the reprogramming.
