SYSTEM AND METHOD FOR AUTOMATICALLY SWITCHING A VEHICLE TO FOLLOW IN A VEHICLE'S AUTONOMOUS DRIVING MODE
Systems and methods for implementing one or more autonomous features for autonomous and semi-autonomous control of one or more vehicles are provided. More specifically, image data may be obtained from an image acquisition device and processed utilizing one or more machine learning models to identify, track, and extract one or more features of the image utilized in decision making processes for providing steering angle and/or acceleration/deceleration input to one or more vehicle controllers. In some instances, techniques may be employed such that the autonomous and semi-autonomous control of a vehicle may change between vehicle follow and lane follow modes. In some instances, at least a portion of the machine learning model may be updated based on one or more conditions.
1 . A method comprising:
following a second vehicle, by a first vehicle, while in an autonomous driving mode;
determining that the second vehicle is no longer visible in an image from a sensor of the first vehicle;
locating a third vehicle to follow in the image; and
changing an autonomous mode to follow the third vehicle.
2 . The method of claim 1 , wherein the second vehicle deviates from a route of the first vehicle.
3 . The method of claim 2 , wherein determining that the second vehicle is no longer visible comprises:
determining an object within the image; and
determining if the object is the second vehicle.
4 . The method of claim 3 , wherein locating the third vehicle to follow in the image comprises automatically drawing a box over the third vehicle in the image.
5 . The method of claim 4 , wherein the box delineates extents of the third vehicle within the image.
6 . The method of claim 5 , wherein a center of the box is determined.
7 . The method of claim 6 , wherein to follow the third vehicle, a position of the center of the box is maintained in subsequent images.
8 . The method of claim 7 , wherein the third vehicle maintains a same route as the first vehicle.
9 . The method of claim 8 , wherein when a third vehicle is no longer visible in the image, maintaining the same route while changing to second autonomous driving mode.
10 . The method of claim 9 , wherein the second autonomous driving mode is a lane follow mode.
11 . A system comprising:
a memory;
a processor in communication with the memory, wherein the processor executes instructions stored in the memory, which cause the processor to execute a method, the method comprising:
following a second vehicle, by a first vehicle, while in an autonomous driving mode;
determining that the second vehicle is no longer visible in an image from a sensor of the first vehicle;
locating a third vehicle to follow in the image; and
changing an autonomous mode to follow the third vehicle.
12 . The system of claim 11 , wherein the second vehicle deviates from a route of the first vehicle.
13 . The system of claim 11 , wherein determining that the second vehicle is no longer visible comprises:
determining an object within the image; and
determining if the object is the second vehicle.
14 . The system of claim 11 , wherein locating the third vehicle to follow in the image comprises automatically drawing a box over the third vehicle in the image, wherein the box delineates extents of the third vehicle within the image, wherein a center of the box is determined, and wherein to follow the third vehicle, a position of the center of the box is maintained in subsequent images.
15 . The system of claim 11 , wherein the third vehicle maintains a same route as the first vehicle.
16 . A non-transitory computer readable medium having stored thereon instructions, which when executed by a processor cause the processor to execute a method, the method comprising:
following a second vehicle, by a first vehicle, while in an autonomous driving mode;
determining that the second vehicle is no longer visible in an image from a sensor of the first vehicle;
locating a third vehicle to follow in the image; and
changing an autonomous mode to follow the third vehicle.
17 . The non-transitory computer readable medium of claim 16 , wherein the second vehicle deviates from a route of the first vehicle.
18 . The non-transitory computer readable medium of claim 16 , wherein determining that the second vehicle is no longer visible comprises:
determining an object within the image; and
determining if the object is the second vehicle.
19 . The non-transitory computer readable medium of claim 16 , wherein locating a third vehicle to follow in the image comprises automatically drawing a box over the third vehicle in the image, wherein the box delineates extents of the third vehicle within the image, wherein a center of the box is determined, and wherein to follow the third vehicle, a position of the center of the box is maintained in subsequent images.
20 . The non-transitory computer readable medium of claim 16 , wherein the third vehicle maintains a same route as the first vehicle.
