Vehicle control device, vehicle control method, and storage medium
A vehicle control device includes a recognizer configured to recognize a surrounding situation of a vehicle and a driving controller configured to perform automated driving for controlling at least one of acceleration, deceleration, and steering of the vehicle on the basis of the situation recognized by the recognizer and map information including a plurality of coordinate points indicating lanes on a route of the vehicle. The driving controller changes a control level of the automated driving in accordance with the number of coordinate points.
1. A vehicle control device comprising:
a recognizer configured to recognize a surrounding situation of a vehicle; and
a driving controller configured to perform automated driving for controlling at least one of acceleration, deceleration, and steering of the vehicle on the basis of the situation recognized by the recognizer and map information including a plurality of coordinate points indicating lanes on a route of the vehicle,
wherein the driving controller changes a control level of the automated driving in accordance with the number of coordinate points,
wherein, when the number of coordinate points exceeds an upper limit number, the driving controller lowers the control level of the automated driving as compared with a case where the number of coordinate points is less than or equal to the upper limit number.
2. The vehicle control device according to claim 1 ,
wherein the driving controller thins out the coordinate points when the number of coordinate points exceeds the upper limit number,
wherein the driving controller does not lower the control level of the automated driving when the number of coordinate points after a thinning-out process is less than or equal to the upper limit number, and
wherein the driving controller lowers the control level of the automated driving when the number of coordinate points after the thinning-out process exceeds the upper limit number.
3. The vehicle control device according to claim 1 ,
wherein the driving controller changes the control level of the automated driving in accordance with a sum of the number of coordinate points located in a first range in front of the vehicle as seen from a position of the vehicle on the route and the number of coordinate points located in a second range behind the vehicle as seen from a position of the vehicle on the route, and
wherein the first range is wider than the second range.
4. The vehicle control device according to claim 1 , wherein the map information includes information about a center or a boundary of the lane represented by a plurality of the coordinate point connected together in an extension direction of the route.
5. A vehicle control method comprising:
recognizing, by a computer mounted in a vehicle, a surrounding situation of the vehicle;
performing, by the computer, automated driving for controlling at least one of acceleration, deceleration, and steering of the vehicle on the basis of the recognized situation and map information including a plurality of coordinate points indicating lanes on a route of the vehicle;
changing, by the computer, a control level of the automated driving in accordance with the number of coordinate points; and
when the number of coordinate points exceeds an upper limit number, lowering by the computer, the control level of the automated driving as compared with a case where the number of coordinate points is less than or equal to the upper limit.
6. A non-transitory computer-readable storage medium storing a program for causing a computer mounted in a vehicle to execute operations, the operations comprising:
recognizing a surrounding situation of the vehicle;
performing automated driving for controlling at least one of acceleration, deceleration, and steering of the vehicle on the basis of the recognized situation and map information including a plurality of coordinate points indicating lanes on a route of the vehicle;
changing a control level of the automated driving in accordance with the number of coordinate points;
when the number of coordinate points exceeds an upper limit number, lowering the control level of the automated driving as compared with a case whether number of coordinate points is less than or equal to the upper limit number.
7. A vehicle control device comprising:
a recognizer configured to recognize a surrounding situation of a vehicle; and
a driving controller configured to perform automated driving for controlling at least one of acceleration, deceleration, and steering of the vehicle on the basis of the situation recognized by the recognizer and map information including a plurality of coordinate points indicating lanes on a route of the vehicle,
wherein the driving controller changes a control level of the automated driving in accordance with the number of coordinate points,
wherein the driving controller determines a traveling mode of the vehicle to be one of a plurality of traveling modes with different the control level, the plurality of traveling modes including a first traveling mode and a second traveling mode in which a task imposed on a driver of the vehicle is less demanding than in the first traveling mode,
wherein, when the number of coordinate points exceeds an upper limit number under the second traveling mode, the driving controller determines changes the traveling mode of the vehicle to the first traveling mode,
wherein the first traveling mode has a task imposed on the driver to operate the steering of the vehicle, and
wherein the second traveling mode does not have the task imposed on the driver to operate the steering of the vehicle.
