Display control device, rewrite progress display control method and computer program product

A rewrite progress display control method for a display control device that is configured to acquire update data from outside and distribute the acquired update data to a rewrite target electronic control unit (ECU), the method comprising the steps of:

• detecting a cancellation regarding a program rewrite from first update data stored in a second storage bank of the rewrite target ECU to second update data acquired from an external device, the program rewrite being performed when a first data storage bank of the rewrite target ECU serves as an active bank;
• distributing the second update data to the rewrite target ECU and instruct the rewrite target ECU to write the second update data thereinto, wherein distribution of the second update data continues when the cancellation is detected during distribution of the second update data;
• giving an instruction to make notification of the progress regarding the program rewrite in a first manner during distribution of the second update data;
• and
• giving an instruction to make notification of the progress regarding the program rewrite in a second manner when the cancellation is detected.

A computer program product for a display control device that includes a computer readable medium and a processor and is configured to acquire update data from outside and distribute the acquired update data to a rewrite target electronic control unit (ECU), the computer program product stored on the computer readable medium and comprising instructions configured to, when executed, cause the processor to:

• detect a cancellation regarding a program rewrite from first update data stored in a second storage bank of the rewrite target ECU to second update data acquired from an external device, the program rewrite being performed when a first data storage bank of the rewrite target ECU serves as an active bank;
• distribute the second update data to the rewrite target ECU and instruct the rewrite target ECU to write the second update data thereinto, wherein distribution of the second update data continues when the cancellation is detected during distribution of the second update data;
• give an instruction to make notification of the progress regarding the program rewrite in a first manner during distribution of the second update data;
• and
• give an instruction to make notification of the progress regarding the program rewrite in a second manner when the cancellation is detected.
