Vehicle control device, vehicle control method, and storage medium

1. A vehicle control device comprising:

a processor configured to:

recognize a surrounding situation of a vehicle; and

control acceleration/deceleration and steering of the vehicle based on the surrounding situation,

wherein the processor determines a search range or a setting range of a target position candidate when a lane change is made in accordance with a type of lane change if the processor causes the vehicle to make the lane change,

wherein the processor determines whether the type of lane change is at least a first type of lane change for traveling along a predetermined route, a second type of lane change for overtaking a preceding vehicle, or a third type of lane change based on a request from an occupant when the processor causes the vehicle to make the lane change, and

wherein the processor widens the search range or the setting range when the type of lane change is the first type as compared with when the type of lane change is the second type or the third type.

2. The vehicle control device according to claim 1 ,

wherein the processor sets the search range or the setting range in an inter-vehicle region closest to the vehicle in a lane of a lane change destination when the type of lane change is the second type or the third type, and

wherein the processor sets the search range or the setting range in a plurality of inter-vehicle regions in the lane of the lane change destination when the type of lane change is the first type.

3. The vehicle control device according to claim 1 ,

wherein the vehicle travels in at least one of a first driving state implemented by the processor and a second driving state in which the number of tasks imposed on a driver is reduced as compared with the first driving state, and

wherein the processor causes the vehicle to make the lane change when the processor causes the vehicle to travel in the first driving state.

4. The vehicle control device according to claim 1 ,

wherein the processor determines a size of the search range or the setting range in accordance with curvature of a curve road when the vehicle is traveling on the curve road.

5. A vehicle control method using a computer mounted in the vehicle, comprising:

recognizing, a surrounding situation of a vehicle;

controlling, acceleration/deceleration and steering of the vehicle based on the surrounding situation;

determining, a search range or a setting range of a target position candidate when a lane change is made in accordance with a type of lane change if the vehicle makes the lane change;

determining whether the type of lane change is at least a first type of lane change for traveling along a predetermined route, a second type of lane change for overtaking a preceding vehicle, or a third type of lane change based on a request from an occupant if the vehicle makes the lane change, and

widening the search range or the setting range when the type of lane change is the first type as compared with when the type of lane change is the second type or the third type.

6. A computer-readable non-transitory storage medium storing a program for causing a computer to:

recognize a surrounding situation of a vehicle;

control acceleration/deceleration and steering of the vehicle based on the surrounding situation;

determine a search range or a setting range of a target position candidate when a lane change is made in accordance with a type of lane change if the vehicle makes the lane change;

determine whether the type of lane change is at least a first type of lane change for traveling along a predetermined route, a second type of lane change for overtaking a preceding vehicle, or a third type of lane change based on a request from an occupant if the vehicle makes the lane change, and

widen the search range or the setting range when the type of lane change is the first type as compared with when the type of lane change is the second type or the third type.
