Abstract

Herein is disclosed a detection device comprising one or more sensors, configured to receive sensor input from a vicinity of a first vehicle, and to generate sensor data representing the received sensor input; one or more processors, configured to detect a second vehicle from the received sensor data; determine from the sensor data a region of a first type relative to the second vehicle and a region of a second type relative to the second vehicle; and control the first vehicle to avoid or reduce travel in the one or more regions of the first type or to travel from a region of the first type to a region of the second type.

First claim

The invention claimed is:

1. A detection device comprising:
one or more sensors, configured to receive sensor input from a vicinity of a first vehicle, and to generate sensor data representing the received sensor input;
one or more processors, configured to
detect a second vehicle from the received sensor data;
determine from the sensor data one or more regions of a first type in a vicinity of the second vehicle and one or more regions of a second type in a vicinity of the second vehicle; and
control the first vehicle to avoid or reduce travel in the one or more regions of the first type, or to travel from a region of the first type to a region of the second type;

wherein the one or more regions of the first type are blind spots of the second vehicle;
wherein the one or more processors are further configured to determine from the sensor data a position of a second vehicle relative to the first vehicle and a side mirror of the second vehicle; and wherein the one or more processors are configured to determine the region of the first type using the position of the second vehicle and
a region between a first axis and a second axis, wherein the first axis intersects the detected side mirror and is perpendicular to a longitudinal axis of the second vehicle and the second axis intersects the first axis and extends at an angle from the first axis, toward a rear of the second vehicle.

2. The detection device of claim 1 , wherein the one or more blind spots are regions in a vicinity of the second vehicle that are not visible from a driver's seat of the second vehicle via any of a front windshield, a rear-view mirror, a left-side-mirror, or a right-side-mirror of the second vehicle.

3. The detection device of claim 1 , wherein the one or more regions of the second type are regions in a vicinity of the second vehicle that are visible from a driver's seat of the second vehicle via any of a front windshield, a rear-view mirror, a left-side-mirror, or a right-side-mirror of the second vehicle.

4. The detection device of claim 1 , wherein the one or more processors are further configured to detect from the sensor data a distance of the second vehicle relative to the first vehicle; and wherein the one or more processors are configured to control the first vehicle to avoid or reduce a duration of time spent in the one or more regions of the first type using the detected distance.

5. The detection device of claim 1 , further comprising a look-up table stored in a memory, the look-up table comprising at least one of locations of regions of the first type of a vehicle make; locations of regions of the first type of a vehicle model; locations of regions of the first type based on a mirror position; locations of regions of the first type based on a carriage type; or any combination thereof.

6. The detection device of claim 1 , wherein determining the position of at least one side mirror of the second vehicle relative to another detected element of the second vehicle comprises determining a position of two side mirrors and determining the one or more regions of the first type as one or more regions along an axis extending at a predetermined angle away from an axis intersecting the two side mirrors.

7. The detection device of claim 1 , wherein the one or more processors are further configured to detect from the sensor data a velocity of the second vehicle relative to the first vehicle; and wherein the one or more processors are configured to control the first vehicle to avoid or reduce a duration of time spent in the one or more regions of the first type using the detected velocity.

8. The detection device of claim 7 , wherein the one or more processors are configured to detect the velocity as a change in two or more detected positions of the second vehicle over a change in time.

9. The detection device of claim 1 , wherein the one or more processors are further configured to detect from the sensor data an acceleration of the second vehicle relative to the first vehicle; and wherein the one or more processors are configured to control the first vehicle to avoid or reduce a duration of time spent in the one or more regions of the first type using the detected acceleration.

10. The detection device of claim 1 , wherein the one or more processors are further configured to determine from the sensor data a position of a second vehicle relative to the first vehicle; and a physical configuration of the second vehicle, and wherein the one or more processors determine the region of the first type and the region of the second type using the position of the second vehicle and the physical configuration of the second vehicle.

11. The detection device of claim 1 , wherein the one or more processors are further configured to controlling the first vehicle to avoid or reduce a duration of time spent in the one or more regions of the first type.

12. A blind spot detection system comprising:
one or more sensors, configured to receive sensor input from a vicinity of a first vehicle, and to generate sensor data representing the received sensor input;
one or more processors, configured to
detect a second vehicle from the received sensor data;
determine from the sensor data a region of a first type relative to the second vehicle and a region of a second type relative to the second vehicle; and
control the first vehicle to avoid or reduce travel in the one or more regions of the first type or to travel from a region of the first type to a region of the second type;

wherein the one or more processors are further configured to detect from the sensor data an acceleration of the second vehicle relative to the first vehicle; and wherein the one or more processors are configured to control the first vehicle to avoid or reduce a duration of time spent in the one or more regions of the first type using the detected acceleration;
wherein the one or more processors are further configured to determine from the sensor data a position of a second vehicle relative to the first vehicle; and a physical configuration of the second vehicle, and wherein the one or more processors determine the region of the first type and the region of the second type using the position of the second vehicle and the physical configuration of the second vehicle;
wherein determining the configuration of the second vehicle comprises at least one of determining a position of at least one side mirror of the second vehicle relative to another detected element of the second vehicle; detecting a make of the second vehicle; detecting a model of the second vehicle; detecting a carriage type of the second vehicle; or any combination thereof.

13. The blind spot detection system of claim 12 , wherein the one or more regions of the first type are blind spots of the second vehicle.

14. The blind spot detection system of claim 12 , wherein the one or more blind spots are regions in a vicinity of the second vehicle that are not visible from a driver's seat of the second vehicle via any of a front windshield, a rear-view mirror, a left-side-mirror, or a right-side-mirror of the second vehicle.

15. The blind spot detection system of claim 12 , wherein the one or more regions of the second type are regions in a vicinity of the second vehicle that are visible from a driver's seat of the second vehicle via any of a front windshield, a rear-view mirror, a left-side-mirror, or a right-side-mirror of the second vehicle.

16. The blind spot detection system of claim 12 , wherein the one or more processors are further configured to detect from the sensor data a distance of the second vehicle relative
