Abstract
A fogging suppression apparatus that suppresses fogging of a window of vehicle, comprises an acquisition unit that acquires an external temperature of the vehicle, a heater that heats the window, the heater differing from an air conditioning apparatus including a blower provided in the vehicle; and a control unit that controls the heater so as to heat the window when the external temperature of the vehicle is lower than or equal to a predetermined temperature and there is a request for activation of the air conditioning apparatus.
Claims7
A fogging suppression apparatus that suppresses fogging of a window of vehicle, comprising:
- a heater that heats the window, the heater differing from an air conditioning apparatus including a blower provided in the vehicle;
- and
- a processor and a memory coupled to the processor and storing instructions that, when executed by the processor, cause the processor to function as:
- an acquisition unit that acquires an external temperature of the vehicle;
- and
- a control unit that performs control of the heater to heat the window when a control start condition in which the external temperature of the vehicle is lower than or equal to a predetermined temperature and there is a request for activation of the air conditioning apparatus,
- wherein the control is a process that includes a first period and a third period for performing the heating of the window and a second period for stopping the heating of the window, and repeats the second period and the third period immediately after the first period, and
- the process is started after the control start condition is met first and continued until a control stop condition is met,
- the first period is set to be longer than or equal to the second period, and the second period is set to be longer than the third period, the third period is set to be longer for a lower external temperature.
A method of controlling a fogging suppression apparatus that suppresses fogging of a window of a vehicle,
- wherein the fogging suppression apparatus includes:
- a heater that heats the window, the heater differing from an air conditioning apparatus including a blower provided in the vehicle, and
- a processor and a memory coupled to the processor and storing instructions that, when executed by the processor, cause the processor to function as:
- an acquisition unit that acquires an external temperature of the vehicle;
- and
- the control method comprises
- performing control of the heater to heat the window when a control start condition in which the external temperature of the vehicle is lower than or equal to a predetermined temperature and there is a request for activation of the air conditioning apparatus,
- wherein the control is a process that includes a first period and a third period for performing the heating of the window and a second period for stopping the heating of the window, and repeats the second period and the third period immediately after the first period, and
- the process is started after the control start condition is met first and continued until a control stop condition is met,
- the first period is set to be longer than or equal to the second period, and the second period is set to be longer than the third period, the third period is set to be longer for a lower external temperature.
