Abstract

Disclosed is a vehicle-mounted electronic device provided with an input unit which designates a destination, an incident-prone area storage unit in which incident-prone area data is stored, a report unit, and a control unit, wherein incident occurrence rates in a plurality of time zones in each of areas or incident occurrence rates in a plurality of time zones in each of facilities within each of the areas are stored in the incident-prone area storage unit, and the control unit calculates the predicted time of arrival at the designated destination, and when detecting that the incident occurrence rate in the area in which the destination is located or the incident occurrence rate in the destination is a preset predetermined value or more in a time zone of a predetermined time period later than the calculated predicted time, causes the report unit to make a report.

Claims

1. A vehicle-mounted electronic device, comprising:

an input portion for designating a destination;

an incident-prone area storage portion in which incident-prone area data is stored;

an indication portion; and

a control portion,

wherein the incident-prone area storage portion stores an incident occurrence rate in each area in each of a plurality of time slots or the incident occurrence rate in each facility within each area in each of the plurality of time slots, and

the control portion calculates a predicted time of arrival at the destination designated, and upon detecting that, in a time slot after a lapse of a predetermined length of time from the calculated predicted time, the incident occurrence rate in an area in which the destination is located or the incident occurrence rate at the destination is not less than a preset predetermined value, the control portion makes the indication portion provide an indication.

2. The vehicle-mounted electronic device according to claim 1, wherein

if the control portion detects that the incident occurrence rate in the area in which the destination is located or the incident occurrence rate at the destination is not less than the predetermined value, and if a stay in a facility as the destination is predicted to be prolonged, the control portion makes the indication portion provide an indication.

3. The vehicle-mounted electronic device according to claim 1, wherein

if the incident occurrence rate at the destination is not less than the predetermined value, the control portion searches for, as an alternative destination, a facility of the same type in a vicinity of the designated destination, which has a value of the incident occurrence rate in the time slot less than the predetermined value.

4. The vehicle-mounted electronic device according to claim 3, wherein

if an appropriate facility as the alternative destination is found, the control portion makes the indication portion provide guidance to the alternative destination, and if an appropriate facility as the alternative destination is not found, the control portion makes the indication portion indicate a warning to watch out.

5. The vehicle-mounted electronic device according to claim 1, wherein

the preset predetermined value is made changeable to an arbitrary value via the input portion.
