Abstract

A vehicle includes a receiving part configured to receive an emergency signal, an alert control part configured to determine a speech speed of an emergency alert based on current position information of the vehicle and map information of surroundings of the vehicle when the emergency signal is received by the receiving part, and an output part configured to output the emergency alert using the speech speed determined by the alert control part.

First claim

What is claimed is:

1. A vehicle comprising:
a receiving part configured to receive an emergency signal;
an alert control part configured to determine a speech speed of an emergency alert based on a positional relationship between (i) a current position indicated by current position information of the vehicle and (ii) a residential area indicated by map information of surroundings of the vehicle when the emergency signal is received by the receiving part; and
an output part configured to output the emergency alert using the speech speed determined by the alert control part.

2. The vehicle according to claim 1 , wherein the alert control part is configured to determine the speech speed to be a first speech speed when the current position is spaced apart by a distance smaller than a predetermined distance from the residential area, and determine the speech speed to be a second speech speed that is slower than the first speech speed when the current position is spaced apart by a distance equal to or larger than the predetermined distance from the residential area.

3. The vehicle according to claim 1 , wherein the alert control part is configured to change a content of the emergency alert based on the current position and a position of a mountainous area or a coastal area indicated by the map information.

4. The vehicle according to claim 1 , further comprising an imaging device,
wherein the alert control part is configured to change the speech speed of the emergency alert based on the number of persons imaged by the imaging device.

5. The vehicle according to claim 1 , further comprising a communication part configured to communicate with other vehicles,
wherein the alert control part is configured to determine a notification area of the emergency alert of each of the vehicles by performing information communication with the other vehicles.

6. The vehicle according to claim 1 , further comprising an operation control part configured to enable autonomous traveling, wherein:
the operation control part is configured to specify a village in a sparsely populated area based on the map information and autonomously travel to the village; and
the output part is configured to output the emergency alert when the vehicle arrives at the village.

7. The vehicle according to claim 1 , wherein the alert control part is configured to control the output part to output the emergency alert during travel or stoppage.

8. A vehicle control method comprising:
receiving an emergency signal;
determining a speech speed of an emergency alert based on a positional relationship between (i) a current position indicated by current position information of a vehicle and (ii) a residential area indicated by map information of surroundings of the vehicle when the emergency signal is received; and
outputting the emergency alert using the speech speed.

9. A non-transitory computer-readable recording medium storing a program executed by a vehicle, wherein the program causes the vehicle to execute:
receiving an emergency signal;
determining a speech speed of an emergency alert based on a positional relationship between (i) a current position indicated by current position information of the vehicle and (ii) a residential area indicated by map information of surroundings of the vehicle when the emergency signal is received; and
outputting the emergency alert using the speech speed.
