Vehicle device

A reprogramming master device as one of a plurality of ECUs connected to an in-vehicle network of a vehicle, the reprogramming master device comprising:

• a processor;
• and
• a memory storing instructions configured to, when executed by the processor, cause the processor to:
• execute control of
• transmission of a file for updating of a program based on an external request to a reprogramming slave device as another one of the ECUs, and
• updating of a program stored in the reprogramming slave device;
• communicate with one or more of the ECUs other than the reprogramming slave device and the reprogramming master device;
• determine whether or not the updating of the program is executable based on a state of the vehicle,
• command the reprogramming slave device to execute the updating of the program, in response to determining that the updating of the program is executable;
• determine whether or not the vehicle is permitted to travel during the updating of the program according to a determination result before commanding the reprogramming slave device to execute the updating of the program, and command a notification medium to notify of travel propriety information as to whether or not the vehicle is permitted to travel during the updating of the program according to the determination result before commanding the reprogramming slave device to execute the updating of the program;
• determine whether or not the vehicle is permitted to travel during the updating of the program according to a determination result after commanding the reprogramming slave device to execute the updating of the program, and command a notification medium to notify of travel propriety information as to whether or not the vehicle is permitted to travel during the updating of the program according to the determination result after commanding the reprogramming slave device to execute the updating of the program;
• calculate a progress level of the updating of the program;
• command notification of the progress level and the travel propriety information, and cause the notification medium to display the progress level and the travel propriety information;
• calculate a remaining time until the vehicle is permitted to travel;
• command notification of the progress level, the remaining time, and the travel propriety information, and cause the notification medium to display the progress level, the remaining time, and the travel propriety information;
• cause the notification medium to display the progress level, the remaining time, the travel propriety information, and an input button for interruption of the updating of the program;
• cause the notification medium to display the input button in a disabled mode, based on a condition that the interruption of the updating of the program is not executable;
• and
• cause the notification medium to display the input button in an enabled mode, based on a condition that the interruption of the updating of the program is executable.
