Communication device, method of controlling communication device, and recording medium
A communication device is a communication device to be installed on a moving body, including a recording unit that records data in which a state value indicating a state of the moving body is recorded, a recording data control unit that controls recording of the recording unit, and a transmission unit that transmits the data recorded by the recording unit to a server device. The recording data control unit records, in the recording unit, first data that is the data in which the state value is changed to a particular value after the moving body is started, and restricts re-recording of the first data in the recording unit until a prescribed condition is established after the first data is recorded.
1 . A vehicle, comprising:
a vehicle control device having a first processor;
a display; and
a communication unit having a second processor and a memory,
wherein
the first processor detects a state of the vehicle based on a detection value of a sensor provided in the vehicle and outputs a detection result to the display,
the display notifies, to a driver of the vehicle, the state of the vehicle by displaying an image corresponding to the state of the vehicle as indicated by the detection result received, and outputs, to the communication unit, an image identification assigned to each of notification contents with a state value which is a value indicating the state of the vehicle and which is associated with each image identification in advance,
the second processor:
when the image identification is received, determines whether or not the image identification received is the image identification of a type that is received for the first time after an ignition power source of the vehicle is turned on;
when it is determined that the image identification is the image identification of the type that is received for the first time after the ignition power source is turned on, and the state value of the image identification received indicates a change to a particular value after the ignition power source of the vehicle is turned on, acquires, from the vehicle control device, a vehicle data including a power source state data indicating a current power source state, a current position data indicating a current position of the vehicle, and a vehicle speed data indicating a current speed of the vehicle;
records, in the memory, the vehicle data acquired in association with the image identification; and
restricts re-recording, in the memory, the image identification having the same image identification acquired and the vehicle data associated with the image identification until a prescribed condition is established.
2 . The vehicle according to claim 1 , wherein
the second processor transmits the image identification and the vehicle data recorded by the memory to an external server device.
3 . The vehicle according to claim 2 , wherein the second processor records the vehicle data of a type specified by the external server device and the image identification of which the state indicates the particular value specified by the external server device.
4 . The vehicle according to claim 2 , wherein the second processor transmits the image identification that is recorded in the memory after the ignition power source is turned on and the vehicle data associated with the image identification, as one piece of data, to the external server device.
5 . The vehicle according to claim 2 , wherein the second processor receives, from the external server device, transmission instruction data indicating a transmission instruction of the image identification,
or when the vehicle is stopped after the ignition power source is turned on, the second processor transmits the image identification recorded in the memory and the vehicle data associated with the image identification to the external server device.
6 . The vehicle according to claim 1 , wherein
the particular value is a value in which the state value indicates an engine failure of the vehicle or a brake failure of the vehicle.
7 . The vehicle according to claim 1 , wherein
the prescribed condition is that the vehicle is stopped or that the external server device issues a transmission instruction of the image identification.
8 . A method of controlling a communication of a vehicle, comprising steps of:
detecting a state of the vehicle based on a detection value of a sensor provided in the vehicle and outputting a detection result to the display;
notifying, to a driver of the vehicle, the state of the vehicle by displaying an image corresponding to the state of the vehicle as indicated by the detection result, and outputting an image identification assigned to each of notification contents with a state value which is a value indicating the state of the vehicle and which is associated with each image identification in advance;
determining whether or not the image identification outputted is the image identification of a type that is outputted for the first time after an ignition power source of the vehicle is turned on;
when determining that the image identification outputted is the image identification of the type that is received for the first time after the ignition power source is turned on, and the state value of the image identification outputted indicates a change to a particular value after the ignition power source of the vehicle is turned on, acquiring, from the sensor, a vehicle data including a power source state data indicating a current power source state, a current position data indicating a current position of the vehicle, and a vehicle speed data indicating a current speed of the vehicle; and
recording, in a memory, the vehicle data acquired in association with the image identification outputted,
wherein the image identification having the same image identification outputted and the vehicle data associated with the image identification is restricted from being re-recorded in the memory until a prescribed condition is established.
9 . A non-transitory computer-readable recording medium recording a communication control program executed by a processor of a vehicle to:
detect a state of the vehicle based on a detection value of a sensor provided in the vehicle and output a detection result to the display;
notify, to a driver of the vehicle, the state of the vehicle by displaying an image corresponding to the state of the vehicle as indicated by the detection result, and output an image identification assigned to each of notification contents with a state value which is a value indicating the state of the vehicle and which is associated with each image identification in advance;
determine whether or not the image identification outputted is the image identification of a type that is outputted for the first time after an ignition power source of the vehicle is turned on;
when determining that the image identification outputted is the image identification of the type that is received for the first time after the ignition power source is turned on, and the state value of the image identification outputted indicates a change to a particular value after the ignition power source of the vehicle is turned on, acquire, from the sensor, a vehicle data including a power source state data indicating a current power source state, a current position data indicating a current position of the vehicle, and a vehicle speed data indicating a current speed of the vehicle;
record, in a memory, the vehicle data acquired in association with the image identification outputted;
and restrict re-recording, in the memory, the image identification having the same image identification acquired and the vehicle data associated with the image identification until a prescribed condition is established.
