Information processing apparatus, information processing method, and vehicle
Provided is an information processing apparatus that includes a vehicle recognition unit that performs recognition of a vehicle in a second lane that is adjacent to a first lane in which an own vehicle is traveling, and has a same traveling direction as the first lane, and a flow detection unit that detects a first difference between a number of vehicles in the second lane by which the own vehicle has been caught up with, and a number of vehicles in the second lane that the own vehicle has caught up with, or a second difference between a number of vehicles in the second lane by which the own vehicle has been overtaken, and a number of vehicles in the second lane that the own vehicle has overtaken on the basis of a recognition result of the vehicle in the second lane.
1. An information processing apparatus, comprising:
a vehicle recognition unit configured to perform recognition of a first vehicle in a first lane that is adjacent to a second lane, wherein
a second vehicle is in the second lane, and
a traveling direction of the first vehicle in the first lane is same as a traveling direction of the second vehicle in the second lane;
a flow detection unit configured to detect one of a first difference between a first number of vehicles in the first lane by which the second vehicle has been caught up with and a second number of vehicles in the first lane that the second vehicle has caught up with, or a second difference between a third number of vehicles in the first lane by which the second vehicle has been overtaken and a fourth number of vehicles in the first lane that the second vehicle has overtaken, based on the recognition of the first vehicle in the first lane;
a situation analysis unit configured to detect a factor, in the first lane, that hinders a flow of the first vehicle in the traveling direction of the second vehicle; and
a lane change processing unit configured to perform, when the factor is not detected, a lane change process related to a lane change of the second vehicle, based on one of the first difference or the second difference is equal to or larger than a threshold value.
2. The information processing apparatus according to claim 1 , further comprising a threshold setting unit configured to set the threshold value, based on a history of a difference value when a lane is changed by an operation of a driver on a road including the first lane and the second lane, wherein
the difference value indicates a value of the first difference or the second difference.
3. The information processing apparatus according to claim 1 , wherein
a difference value indicates a value of the first difference or the second difference, and
the lane change processing unit is further configured to determine whether to perform the lane change process based on the difference value, based on
at least one of an inter-vehicle distance between a third vehicle that is in front of the second vehicle in the second lane and the second vehicle, or
a speed of the second vehicle.
4. The information processing apparatus according to claim 1 , wherein
the lane change process includes at least one of a proposal of the lane change to the first lane or control of the lane change of the second vehicle to the first lane.
5. The information processing apparatus according to claim 1 , wherein
in a case where the first vehicle in the first lane next to the second vehicle has changed to a third vehicle, the flow detection unit is further configured to determine one of whether the second vehicle has been caught up with or overtaken by the third vehicle, or whether the second vehicle has caught up with or overtaken the third vehicle, based on a comparison of a speed of the second vehicle and a speed of the third vehicle.
6. The information processing apparatus according to claim 1 , further comprising a presentation control unit configured to control a presentation of a situation of a flow of the first vehicle in the first lane, based on one of the first difference or the second difference.
7. An information processing method, comprising:
performing recognition of a first vehicle in a first lane that is adjacent to a second lane, wherein
a second vehicle is in the second lane, and
a traveling direction of the first vehicle in the first lane is same as a traveling direction of the second vehicle in the second lane;
detecting one of a first difference between a first number of vehicles in the first lane by which the second vehicle has been caught up with and a second number of vehicles in the first lane that the second vehicle has caught up with, or a second difference between a third number of vehicles in the first lane by which the second vehicle has been overtaken and a fourth number of vehicles in the first lane that the second vehicle has overtaken, based on the recognition of the first vehicle in the first lane;
detecting a factor, in the first lane, that hinders a flow of the first vehicle in the traveling direction of the second vehicle; and
performing, when the factor is not detected, a lane change processing related to a lane change of the second vehicle, based on one of the first difference or the second difference is equal to or larger than a threshold value.
8. A non-transitory computer-readable medium having stored thereon computer-executable instructions which, when executed by a processor, cause the processor to execute operations, the operations comprising:
performing recognition of a first vehicle in a first lane that is adjacent to a second lane, wherein
a second vehicle is in the second lane, and
a traveling direction of the first vehicle in the first lane is same as a traveling direction of the second vehicle in the second lane;
detecting one of a first difference between a first number of vehicles in the first lane by which the second vehicle has been caught up with and a second number of vehicles in the first lane that the second vehicle has caught up with, or a second difference between a third number of vehicles in the first lane by which the second vehicle has been overtaken and a fourth number of vehicles in the first lane that the second vehicle has overtaken, based on the recognition of the first vehicle in the first lane;
detecting a factor, in the first lane, that hinders a flow of the first vehicle in the traveling direction of the second vehicle; and
performing, when the factor is not detected, a lane change processing related to a lane change of the second vehicle, based on one of the first difference or the second difference is equal to or larger than a threshold value.
9. A vehicle, comprising:
a vehicle recognition unit configured to perform recognition of a specific vehicle in a first lane that is adjacent to a second lane, wherein
the vehicle is in the second lane, and
a traveling direction of the specific vehicle in the first lane is same as a traveling direction of the vehicle in the second lane;
a flow detection unit configured to detect one of a first difference between a first number of vehicles in the first lane by which the vehicle has been caught up with and a second number of vehicles in the first lane that the vehicle has caught up with, or a second difference between a third number of vehicles in the first lane by which the vehicle has been overtaken and a fourth number of vehicles in the first lane that the vehicle has overtaken, based on the recognition of the specific vehicle in the first lane;
a situation analysis unit configured to detect a factor, in the first lane, that hinders a flow of the specific vehicle in the traveling direction of the vehicle; and
a motion control unit configured to control the vehicle to perform, when the factor is not detected, a lane change, based on one of the first difference or the second difference is equal to or larger than a threshold value.
