Object detection
A computer that includes a processor and a memory, the memory including instructions executable by the processor to, upon initiating a lane change maneuver from a first lane to a second lane by a first vehicle including a first predicted trajectory, determine a second predicted trajectory for a second vehicle in a third lane based on one or more side-looking sensors. Based on determining that a distance between the first predicted trajectory and the second predicted trajectory is greater than a threshold, the first vehicle can be actuated to perform the lane change maneuver.
1 . A system, comprising:
a computer that includes a processor and a memory, the memory including instructions executable by the processor to:
upon initiating a lane change maneuver from a first lane to a second lane by a first vehicle including a first predicted trajectory, determine a second predicted trajectory for a second vehicle in a third lane based on one or more side-looking video images and side-looking Doppler radar images having overlapping fields of view; and
based on determining that a distance between the first predicted trajectory and the second predicted trajectory is greater than a threshold, actuate the first vehicle to perform the lane change maneuver.
2 . The system of claim 1 , wherein performing the lane change maneuver includes operating the first vehicle on the first predicted trajectory.
3 . The system of claim 1 , wherein, when the distance between the first predicted trajectory and the second predicted trajectory is less than the threshold, cancel the lane change maneuver.
4 . The system of claim 3 , wherein cancelling the lane change maneuver includes determining a third predicted trajectory for the first vehicle.
5 . The system of claim 4 , wherein cancelling the lane change maneuver includes operating the first vehicle on the third predicted trajectory.
6 . The system of claim 1 , wherein the lane change maneuver is initiated based on one or more of detecting a leading vehicle traveling more slowly in the same traffic lane as the first vehicle and a user indicating a lane change maneuver request.
7 . The system of claim 1 , wherein a second vehicle location, speed, and direction are determined based on processing side-looking video data and side-looking radar data with a neural network.
8 . The system of claim 1 , wherein a second vehicle location, distance, and speed are determined based on processing side-looking video data and side-looking radar data with image processing software.
9 . The system of claim 1 , wherein determining the trajectory for the second vehicle is based on detecting a flashing turn indicator on the second vehicle.
10 . A method, comprising:
upon initiating a lane change maneuver from a first lane to a second lane by a first vehicle including a first predicted trajectory, determining a second predicted trajectory for a second vehicle in a third lane based on one or more side-looking video images and side-looking Doppler radar images having overlapping fields of view; and
based on determining that a distance between the first predicted trajectory and the second predicted trajectory is greater than a threshold, actuating the first vehicle to perform the lane change maneuver.
11 . The method of claim 10 , wherein performing the lane change maneuver includes operating the first vehicle on the first predicted trajectory.
12 . The method of claim 10 , wherein, when the distance between the first predicted trajectory and the second predicted trajectory is less than the threshold, cancel the lane change maneuver.
13 . The method of claim 12 , wherein cancelling the lane change maneuver includes determining a third predicted trajectory for the first vehicle.
14 . The method of claim 13 , wherein cancelling the lane change maneuver includes operating the first vehicle on the third predicted trajectory.
15 . The method of claim 10 , wherein the lane change maneuver is initiated based on one or more of detecting a leading vehicle traveling more slowly in the same lane as the first vehicle and a user indicating a lane change maneuver request.
16 . The method of claim 10 , wherein a second vehicle location, speed, and direction are determined based on processing side-looking video data and side-looking radar data with a neural network.
17 . The method of claim 10 , wherein a second vehicle location, distance, and speed are determined based on processing side-looking video data and side-looking radar data with image processing software.
18 . The method of claim 10 , wherein determining the trajectory for the second vehicle is based on detecting a flashing turn indicator on the second vehicle.
