5 . The vehicular apparatus according to claim 1 , further comprising:
a detector configured to detect whether or not a power supply voltage drops below a predetermined reference voltage,
wherein the maintainer is further configured to maintain the drawer at the operating state during a period until the detector detects that the power supply voltage drops below the predetermined reference voltage, after the input device receives the stop signal.
6 . The vehicular apparatus according to claim 1 ,
wherein the drawer is further configured to draw at least one of a message indicating stop of the vehicular apparatus or an image indicating the stop of the vehicular apparatus, in response to that the input device receives the stop signal.
7 . The vehicular apparatus according to claim 1 , further comprising:
a device configured to be used when the drawer executes the drawing on the display device,
wherein the maintainer is further configured to maintain the device at an operating state.
8 . The vehicular apparatus according to claim 7 ,
wherein the device is a meter display circuit.
9 . The vehicular apparatus according to claim 1 ,
wherein the stop signal indicating the operation for stopping the vehicle is a signal for turning off an accessory of the vehicle.
10 . The vehicular apparatus according to claim 1 , wherein:
the first functional device is further configured to be operated on a first operating system being a real-time system;
the second functional device is further configured to be operated on a second operating system being a general-purpose system; and
each of the first operating system and the second operating system is configured to be operated in a virtual environment.
11 . The vehicular apparatus according to claim 10 , further comprising:
a controller having a processor configured to cause the real-time system and the general-purpose system to execute an operation, wherein
the display device is a plurality of display devices including a center display and a meter display of the vehicle,
the general-purpose system is configured to execute displaying on the center display information of a multimedia system of the vehicle, by controlling a center display circuit of the vehicle, and
the real-time system is configured to execute displaying on the meter display information related to a state of the vehicle, by controlling a meter display circuit of the vehicle.
12 . The vehicular apparatus according to claim 1 ,
wherein the maintainer is further configured to end the operating state of the drawer by starting the ending sequence.
13 . The vehicular apparatus according to claim 1 , wherein
the notice information includes information indicating that a remaining amount of fuel is low.
14 . The vehicular apparatus according to claim 1 , wherein
the warning information includes information stipulated by law.
15 . The vehicular apparatus according to claim 1 , wherein
the display device is a meter display of the vehicle, and
a speedometer or a tachometer in the meter display fades out, on a condition that the meter display displays the message related to the ending of display.
16 . The vehicular apparatus according to claim 1 , wherein
the warning information indicates whether a seatbelt of the vehicle is fastened.
17 . The vehicular apparatus according to claim 1 , wherein
the continuation request signal is a signal that is transmitted from an external ECU via a CAN line of the vehicle.
18 . A vehicular apparatus comprising:
a processor and a memory that stores instructions configured to, when executed by the processor, cause the processor to:
execute drawing on a display device of a vehicle;
receive a stop signal indicating an operation for stopping the vehicle;
execute a plurality of functions including a first function for displaying information related to a state of the vehicle on the display device and a second function for displaying information of a multimedia system;
maintain the processor at an operating state and execute on the display device display of a message related to ending of display, warning information, and notice information to be noted for next usage of the vehicle during a period until a continuation request signal becoming the off level, in response to that the processor receives the stop signal, the continuation request signal being a signal for controlling the vehicular apparatus to continue an operation including the display of the message, the warning information, and the notice information; and
start an ending sequence for sequentially ending the functions to stop the processor in response to the continuation request signal becoming the off level.
