Claims17
A trailer, comprising:
- one or more adjustable suspension actuators;
- an actuator control module configured to actuate the one or more adjustable suspension actuators;
- a camera configured to capture images of a road in front of the trailer;
- a curvature module configured to determine a curvature of the road in front of the trailer based on an image from the camera;
- an adjustment module configured to selectively adjust the one or more adjustable suspension actuators while the trailer is moving based on the curvature of the road in front of the trailer including:
- adjusting the one or more adjustable suspension actuators and lowering a right side of the trailer when the road in front of the trailer curves rightward;
- adjusting the one or more adjustable suspension actuators and increasingly lowering the right side of the trailer as a radius of the curvature of the road in front of the trailer rightward decreases;
- and
- adjusting the one or more adjustable suspension actuators and decreasingly lowering the right side of the trailer as the radius of the curvature of the road in front of the trailer rightward increases.
