It should be noted that judging to set to the terminal of user by vehicle device there are during article in car refrigerator
Preparation send the solicited message for opening refrigerator, and user can carry out response for the solicited message.If user agrees to that the request is believed
Breath, then control car refrigerator to open.
S25, if capacitance present is less than or equal to the second predetermined threshold value, determines whether capacitance present is less than or equal to
3rd predetermined threshold value.
Wherein, the first predetermined threshold value is less than the 3rd predetermined threshold value.
S26, if capacitance present is less than or equal to the 3rd predetermined threshold value, judges article is not present in car refrigerator.
Specifically, in order to avoid in car refrigerator article bit by bit taken away, but be not removed what is brought completely
Erroneous judgement, can set the capacitance lower threshold that article is not present in car refrigerator, i.e. the 3rd predetermined threshold value.If capacitance present is small
In equal to the 3rd predetermined threshold value, then judge article is not present in refrigerator.If capacitance present is more than the 3rd predetermined threshold value, return
Step S21.
