Abstract
An automated speed control system includes a ranging-sensor, a camera, and a controller. The ranging-sensor detects a lead-speed of a lead-vehicle traveling ahead of a host-vehicle. The camera detects an object in a field-of-view. The controller is in communication with the ranging-sensor and the camera. The controller is operable to control the host-vehicle. The controller determines a change in the lead-speed based on the ranging-sensor. The controller reduces a host-speed of the host-vehicle when the lead-speed is decreasing, no object is detected by the camera, and while a portion of the field-of-view is obscured by the lead-vehicle.
Claims22
A system comprising:
- a controller configured to:
- receive, from a ranging sensor that is local to a host vehicle, signal characteristics associated with a lead vehicle traveling ahead of the host vehicle in a lane adjacent to that of the host vehicle;
- receive, from a camera that is local to the host vehicle, images;
- and
- decrease a speed of the host vehicle responsive to the controller determining that:
- a speed of the lead vehicle has decreased an amount based on the signal characteristics received from the ranging sensor;
- an object exists in front of the host vehicle based on one or more of the images;
- and
- a portion of interest within the one or more of the images is occluded by the lead vehicle, the portion of interest corresponding to a portion of the object.
A system comprising:
- a controller configured to:
- receive, from a ranging sensor that is local to a host vehicle, signal characteristics associated with objects around the host vehicle;
- receive, from a camera that is local to the host vehicle, images;
- and
- decrease a speed of the host vehicle responsive to the controller determining that:
- a speed of a lead vehicle in a lane adjacent to that of the host vehicle has decreased by an amount based on the signal characteristics received from the ranging sensor;
- an obstruction exists ahead of the host vehicle in a path of the host vehicle based on the signal characteristics received from the ranging sensor;
- the obstruction cannot be determined within one or more of the images received from the camera;
- and
- a conflict exists between the signal characteristics and the images regarding the obstruction.
A system comprising:
- a controller configured to:
- receive, from a ranging sensor that is local to a host vehicle, signal characteristics associated with objects surrounding the host vehicle;
- receive, from a camera that is local to the host vehicle, images;
- and
- decrease a speed of the host vehicle responsive to the controller determining that:
- a speed of a lead vehicle traveling ahead of the host vehicle in a lane adjacent to that of the host vehicle has decreased an amount based on the signal characteristics received from the ranging sensor;
- an object exists in front of the host vehicle based on the signal characteristic received from the ranging sensor;
- and
- a portion of interest corresponding to a location of the object is occluded by the lead vehicle in one or more of the images received by the camera.
