Mobile object control device and mobile object control method
A hardware processor of a mobile object executes the program stored in a storage device to acquire information indicating a road situation in a traveling direction of a mobile object; to recognize whether the mobile object is moving on a roadway or a predetermined region different from the roadway; to recognize presence of a contact portion between the sidewalk and the predetermined region in the traveling direction of the mobile object; to control the speed of the mobile object at least partially, and limit a speed at which the mobile object is moving on the roadway to a first speed and limit a speed at which the mobile object is moving on a sidewalk to a second speed slower than the first speed; and to bring a speed of the mobile object closer to the second speed when the mobile object is moving on the roadway, the contact portion is recognized within a predetermined range from the mobile object, and the road situation is in a predetermined state.
1. A mobile object control device for a mobile object capable of moving on both a roadway and a sidewalk, comprising:
a storage device storing a program; and
a hardware processor,
wherein the hardware processor executes the program stored in the storage device to:
acquire information indicating a road situation of the roadway in a traveling direction of the mobile object which is moving on the roadway;
recognize whether the mobile object is moving on the roadway or the sidewalk;
recognize presence of a contact portion between the sidewalk and the roadway in the traveling direction of the mobile object, the contact portion being provided at a boundary between the sidewalk and the roadway, the contact portion being a portion in which a load is less than in other portions of the boundary when the mobile object passes through;
control the speed of the mobile object at least partially;
limit a speed at which the mobile object is moving on the roadway to a first speed;
limit a speed at which the mobile object is moving on the sidewalk to a second speed slower than the first speed; and
bring a speed of the mobile object closer to the second speed when the mobile object is moving on the roadway, the contact portion is recognized within a first predetermined range from the mobile object in the traveling direction of the mobile object, and the road situation is in a predetermined state within a second predetermined range from the mobile object in the traveling direction of the mobile object, the first predetermined range being shorter than or the same as the second predetermined range,
wherein the hardware processor determines that the road situation is a predetermined state when it is recognized based on the acquired information that a speed of another mobile object moving in the same direction as the mobile object is greater than a threshold A within the second predetermined range in the traveling direction of the mobile object.
2. The mobile object control device according to claim 1 ,
wherein the hardware processor questions about an intention to enter the sidewalk using an interface device when the mobile object is moving on the roadway, the contact portion is recognized within the first predetermined range from the mobile object, and the road situation is a predetermined state, and a speed of the mobile object is brought closer to the second speed when a positive response is obtained.
3. The mobile object control device according to claim 1 ,
wherein the hardware processor determines that the road situation is a predetermined state when it is recognized based on the acquired information that a dead end is within the second predetermined range in the traveling direction of the mobile object.
4. The mobile object control device according to claim 1 ,
wherein the hardware processor determines that the road situation is a predetermined state when it is recognized based on the acquired information that a construction site is within the second predetermined range in the traveling direction of the mobile object.
5. The mobile object control device according to claim 1 ,
wherein the hardware processor determines that the road situation is a predetermined state when it is recognized based on the acquired information that traffic congestion occurs within the second predetermined range in the traveling direction of the mobile object.
6. The mobile object control device according to claim 1 ,
wherein the hardware processor determines that the road situation is a predetermined state when it is recognized based on the acquired information that a predetermined number of types or more of mobile objects coexist within the second predetermined range in the traveling direction of the mobile object.
7. The mobile object control device according to claim 1 , wherein the hardware processor determines that the road situation is a predetermined state when it is recognized based on the acquired information that the number of large vehicles is equal to or greater than a threshold B within the second predetermined range in the traveling direction of the mobile object.
8. The mobile object control device according to claim 1 ,
wherein the hardware processor recognizes whether the mobile object is moving on the roadway or the sidewalk based on an output of an outside world detection device detecting an outside situation of the mobile object.
9. The mobile object control device according to claim 1 ,
wherein the hardware processor recognizes whether the mobile object is moving on the roadway or the sidewalk based on a manipulation of an occupant of the mobile object on a switch provided inside the mobile object.
10. The mobile object control device according to claim 1 ,
wherein, when the hardware processor recognizes that the mobile object is moving on the sidewalk, the hardware processor causes an external report device to report the mobile object which is moving on the sidewalk to the outside of the mobile object.
11. A mobile object control method using a computer controlling a mobile object which is capable of moving both on a roadway and a sidewalk, the method comprising:
acquiring information indicating a road situation of the roadway in a traveling direction of the mobile object which is moving on the roadway;
recognizing whether the mobile object is moving on the roadway or the sidewalk;
recognizing presence of a contact portion between the roadway and the sidewalk in the traveling direction of the mobile object, the contact portion being provided at a boundary between the sidewalk and the roadway, the contact portion being a portion in which a load is less than in other portions of the boundary when the mobile object passes through;
controlling the speed of the mobile object at least partially;
limiting a speed at which the mobile object is moving on the roadway to a first speed;
limiting a speed at which the mobile object is moving on the sidewalk to a second speed slower than the first speed; and
bringing the speed of the mobile object closer to the second speed when the mobile object is moving on the roadway, the contact portion is recognized within a first predetermined range from the mobile object in the traveling direction of the mobile object, and the road situation is a predetermined state within a second predetermined range from the mobile object in the traveling direction of the mobile object, the first predetermined range being shorter than or the same as the second predetermined range,
wherein the method further comprises determining that the road situation is a predetermined state when it is recognized based on the acquired information that a speed of another mobile object moving in the same direction as the mobile object is greater than a threshold A within the second predetermined range in the traveling direction of the mobile object.
12. The mobile object control device according to claim 1
wherein the hardware processor suggests deceleration to an occupant of the mobile object using an interface device when the mobile object is moving on the roadway, the contact portion is recognized within the first predetermined range from the mobile object, and the road situation is in a predetermined state.
13. The mobile object control method according to claim 11 , further comprising
suggesting deceleration to the occupant using an interface device when the mobile object is moving on the roadway, the contact portion is recognized within the first predetermined range from the mobile object, and the road situation is in a predetermined state.
