Vehicle apparatus and control method

A method for controlling a device for a vehicle, the method comprising:

• controlling one or more displays based on a first System on Chip (SoC) being in a normal mode;
• and
• controlling one or more displays that are different from the one or more displays for the first SoC based on a second SoC being in the normal mode,
• wherein the first SoC and the second SoC are connected to a switch,
• wherein the switch is connected to a memory for sharing data between the first SoC and the second SoC and processing a fault for the first SoC,
• wherein data for the first SoC in the normal mode is stored in the memory,
• wherein the switch includes an upstream port and a Non-Transparent (NT) port,
• wherein the upstream port is connected to the first SoC and the NT port is connected to the second SoC, and
• wherein, based on the first SoC being in a fault mode and the second SoC being in the normal mode, (i) controlling of a display for the first SoC is processed based on the second SoC, the switch, and the memory, and (ii) the upstream port is connected to the second SoC and the NT port is connected to the first SoC to enable the second SoC to access, through the upstream port, the data for the first SoC in the normal mode stored in the memory communicate with the memory, and continue output of information for the first SoC on the display for the first SoC without requiring a hardware reset operation of the first SoC.
