Vehicle display apparatus

A vehicle display apparatus comprising:

• a display that is mounted on a vehicle and displays vehicle information;
• any one or both of i) at least one light-emitting element and ii) a speaker;
• a display drive unit that drives the display;
• and
• a control unit that controls the display drive unit so as to display an image on the display and that controls an operation of at least one of the at least one light-emitting element and the speaker, wherein
• the control unit receives image data, generates a first error detection code based on the image data, and transmits only the image data or both the image data and the first error detection code to the display drive unit,
• the display drive unit generates a second error detection code based on the image data received from the control unit or separates only the first error detection code from the image data and the first error detection code, received by the display drive unit, and outputs as the second error detection code,
• the control unit or the display drive unit determines a match between the first error detection code input to the control unit and the second error detection code generated or output by the display drive unit, and
• the control unit is further configured to:
• determines whether a notification is necessary by detecting whether an error recognizable by a user of the vehicle has occurred in the image on the display based on determining a mismatch between the first error detection code input to the control unit and the second error detection code generated or output by the display drive unit;
• and
• when the notification is determined to be necessary, generates notification information for notifying that reliability of the image on the display has degraded and outputs the generated notification information to control the operation of at least any one of the at least one light-emitting element and the speaker or outputs the generated notification information to a higher-level device of the vehicle display apparatus so as to provide the notification via the higher-level device.
