Abstract
An active suspension system senses roadway defects and adjusts an active and controllable suspension system of the vehicle before tires come in contact with the defect. The active suspension system identifies a type of defect or debris, e.g., pothole, bump, object, etc., along with the size, width, depth, and/or height information of the defect to more accurately control operation of the suspension system to prepare for, or avoid contact with the roadway defects and obstacles. Imaging techniques are employed to identify the defect or debris. Operation of a serviced cruise control system is controlled to enhance passenger safety and comfort.
