Abstract
Embodiments are presented herein for trailer sway detection and mitigation using a camera mirror system. In one embodiment, a vehicle controller is provided comprising: one or more processors; a non-transitory computer-readable medium; and program instructions stored on the non-transitory computer-readable medium. When executed by the one or more processors, the program instructions cause the one or more processors to: monitor images captured by at least one image capture device to detect sway of a trailer being towed by a tractor; and in response to detecting sway of the trailer, cause a braking system to apply a brake to attempt to reduce to the sway of the trailer.
Claims21
A vehicle controller comprising:
- one or more processors;
- a non-transitory computer-readable medium;
- and
- program instructions stored on the non-transitory computer-readable medium that, when executed by the one or more processors, cause the one or more processors to:
- monitor images captured by at least one image capture device to detect sway of a trailer being towed by a tractor;
- and
- in response to detecting sway of the trailer, cause a braking system to apply a brake to attempt to reduce to the sway of the trailer.
A method comprising:
- performing in a vehicle comprising a tractor, a trailer towed by the tractor, and at least one image capture device:
- analyzing images captured by the at least one capture device to determine a position of a trailing edge of the trailer over a period of time;
- detecting a sway of the trailer based on the position of the trailing edge of the trailer over the period of time;
- and
- in response to detecting the sway of the trailer, attempting to reduce the sway of the trailer.
A tractor comprising:
- at least one image capture device;
- means for detecting sway of a trailer being towed by the tractor using images captured by the at least one image capture device;
- and
- means for applying a brake to attempt to reduce the sway of the trailer.
