Autonomous driving vehicle
The vehicle of the present disclosure includes a sensor for recognizing an object around the vehicle, at least one processor, and at least one memory storing a plurality of instructions executable by the at least one processor. The plurality of instructions causes the at least one processor to store data acquired by the sensor during the autonomous driving, and to suppress a storage distance of the data when a speed of the vehicle is low, as compared to when the speed of the vehicle is high.
1 . A vehicle travelable by autonomous driving, comprising:
a sensor configured to recognize an object around the vehicle;
at least one processor; and
at least one memory storing a plurality of instructions executable by the at least one processor,
wherein the plurality of instructions is configured to cause the at least one processor to:
store data acquired by the sensor during execution of the autonomous driving, and
suppress a storage distance of the data in response to a speed of the vehicle being low, as compared to in response to the speed of the vehicle being high.
2 . The vehicle according to claim 1 , wherein the plurality of instructions is configured to further cause the at least one processor to:
suppress a maximum speed of the vehicle in response to an available capacity of a storage area for storing the data being small, as compared to in response to the available capacity of the storage area for storing the data being large.
3 . The vehicle according to claim 2 , wherein the plurality of instructions is configured to further cause the at least one processor to suppress the maximum speed in proportion to a difference between the available capacity and a threshold.
4 . The vehicle according to claim 1 , wherein
the sensor is a LiDAR, and
the plurality of instructions is configured to further cause the at least one processor to:
change a storage distance of point group data acquired by the LiDAR according to the speed.
5 . The vehicle according to claim 4 , wherein the storage distance corresponds to a distance of a point group at a position farthest from the vehicle among a plurality of point groups of which data is stored in the at least one memory.
6 . The vehicle according to claim 4 , wherein the plurality of instructions is configured to further cause the at least one processor to set a distance required for the vehicle to stop as a minimum storage distance for the storage distance of the point group data.
7 . The vehicle according to claim 1 , wherein
the sensor includes:
a front sensor configured to recognize an object in front of the vehicle, and
a rear sensor configured to recognize an object behind the vehicle, and
the plurality of instructions is configured to further cause the at least one processor to:
suppress a storage distance of front data acquired by the front sensor when the speed is low, as compared to when the speed is high, and
suppress a storage distance of rear data acquired by the rear sensor in response to a maximum speed set for a multi-lane road on which the vehicle travels being low, as compared to when the maximum speed set for the multi-lane road on which the vehicle travels being high.
8 . The vehicle according to claim 1 , wherein
the sensor is a camera, and
the plurality of instructions is configured to further cause the at least one processor to:
change an effective distance of image data acquired by the camera in accordance with the speed by changing an image compression rate or a sampling rate of the camera in accordance with the speed.
