Abstract

An information processing system includes: an information acquisition unit that acquires traveling area information of the vehicle; an entry determination unit that determines whether the vehicle has entered a specific range; an area information storage unit that stores the traveling area information when the vehicle has entered the specific range; a reception unit that receives a stop signal including information on a stop position of a different vehicle different from the vehicle when the different vehicle stops traveling or is in a state difficult to continue normally traveling; a relation determination unit that determines a positional relationship between the different vehicle and the vehicle, based on the information on the stop position and the traveling area information; and a processing execution unit that executes a predetermined process in accordance with a determination result.

Claims

1. An information processing system arranged on a vehicle, the information processing system comprising a CPU and memory configured to:

acquire traveling area information on an area where the vehicle travels;

determine whether the vehicle has entered a specific area;

store the acquired traveling area information when that the vehicle has entered the specific area;

receive a stop signal as a signal including information on a stop position of a different vehicle different from the vehicle on which the information processing system is arranged, the stop signal being transmitted from an external device outside of the vehicle when the different vehicle stops traveling or when receiving a signal indicative of an abnormal state of the different vehicle;

determine a positional relationship between the different vehicle and the vehicle, based on the information on the stop position included in the received stop signal and the stored traveling area information;

execute a predetermined process in accordance with the determined positional relationship between the different vehicle and the vehicle, the predetermined process including at least one of displaying a warning screen on display device of the vehicle, emitting a warning sound from a speaker of the vehicle, and controlling the vehicle to allow the vehicle to pass through the specific area;

wherein the external device stores a vehicle ID of the vehicle when the vehicle has entered the specific area and stores at least one additional vehicle ID associated with at least one additional vehicle when the at least one additional vehicle has entered the specific area, the vehicle ID and the at least one additional vehicle ID being stored in a priority order based on an order in which the vehicle ID and the at least one additional vehicle ID are received; and

wherein the external device transmits the stop signal to the vehicle and the at least one additional vehicle based on the priority order.

2. The information processing system according to claim 1, the CPU and memory being further configured to:

detect a position of the vehicle,

the stop signal including one or more sets of range information which indicates a range defined in accordance with a distance from a position at which the different vehicle stops traveling; and

determine the positional relationship between the different vehicle and the vehicle, based on the detected position of the vehicle and the range information.

3. The information processing system according to claim 1, the CPU and memory being further configured to:

detect a position of the vehicle;

store information indicating a position of the specific area; and

determine whether the vehicle has entered the specific area, based on a comparison between the detected position of the vehicle and the stored position of the specific area.

4. The information processing system according to claim 1, the CPU and memory being further configured to:

receive a predetermined wireless signal transmitted from a signal transmission device disposed along a road and transmitting the wireless signal; and

determine that the vehicle has entered the specific area when the predetermined wireless signal is received.

5. The information processing system according to claim 1, the CPU and memory being further configured to:

determine whether the vehicle is located in front of the different vehicle in a traveling direction; and

end the process when the vehicle is located in front of the different vehicle in the traveling direction.

6. The information processing system according to claim 1, wherein:

the traveling area information includes at least one of information for specifying a road, information for specifying a predetermined range of the road, and information for specifying a traveling direction.

7. A portable terminal device comprising a CPU and memory configured to:

acquire traveling area information on an area where a vehicle travels;

determine whether the vehicle has entered a specific area;

store the acquired traveling area information when the vehicle has entered the specific area;

receive a stop signal as a signal including information on a stop position of a different vehicle different from the vehicle, the stop signal being transmitted from an external device outside of the vehicle when the different vehicle stops traveling or when receiving a signal indicative of an abnormal state of the different vehicle;

determine a positional relationship between the different vehicle and the vehicle, based on the information on the stop position included in the received stop signal and the stored traveling area information;

execute a predetermined process in accordance with the positional relationship between the different vehicle and the vehicle, the predetermined process including at least one of displaying a warning screen on display device of the vehicle, emitting a warning sound from a speaker of the vehicle, and controlling the vehicle to allow the vehicle to pass through the specific area;

wherein the external device stores a vehicle ID of the vehicle when the vehicle has entered the specific area and stores at least one additional vehicle ID associated with at least one additional vehicle when the at least one additional vehicle has entered the specific area, the vehicle ID and the at least one additional vehicle ID being stored in a priority order based on an order in which the vehicle ID and the at least one additional vehicle ID are received; and

wherein the external device transmits the stop signal to the vehicle and the at least one additional vehicle based on the priority order.

8. A non-transitory tangible computer-readable storage medium comprising an instruction executed by a computer, the instruction including:

acquiring traveling area information on an area where a vehicle travels;

determining whether the vehicle has entered a specific area;

storing acquired traveling area information when determined that the vehicle has entered the specific area;

receiving a stop signal as a signal including information on a stop position of a different vehicle different from the vehicle, the stop signal being transmitted from an external device outside of the vehicle when the different vehicle stops traveling or when receiving a signal indicative of an abnormal state of the different vehicle;

determining a positional relationship between the different vehicle and the vehicle, based on the information on the stop position included in the received stop signal and the stored traveling area information; and

executing a predetermined process in accordance with a determination result of the positional relationship, the predetermined process including at least one of displaying a warning screen on display device of the vehicle, emitting a warning sound from a speaker of the vehicle, and controlling the vehicle to allow the vehicle to pass through the specific area;

wherein the external device stores a vehicle ID of the vehicle when the vehicle has entered the specific area and stores at least one additional vehicle ID associated with at least one additional vehicle when the at least one additional vehicle has entered the specific area, the vehicle ID and the at least one additional vehicle ID being stored in a priority order based on an order in which the vehicle ID and the at least one additional vehicle ID are received; and

wherein the external device transmits the stop signal to the vehicle and the at least one additional vehicle based on the priority order.
