1. A system for determining range of a vehicle, the system comprising:
- a camera configured to view a first region of interest including the vehicle and generate an electrical image of the region;
a sonar sensor configured to detect objects within a second region of interest;
a processor in electrical communication with the camera to receive the electrical image, wherein the processor is configured to identify a plurality of windows within the electrical image, each window of the plurality of windows corresponding to a predetermined physical size and target range from the camera, the processor being further configured to evaluate characteristics of a candidate object in relation to each window to identify the vehicle; and
the processor in electrical communication with the sonar sensor, the processor configured to identify objects detected by the sonar sensor and determine the range of the objects detected by the sonar sensor.

Abstract
A system for determining range and lateral position of a vehicle is provided. The system includes a camera, a sonar and a processor. The camera is configured to view a long range region of interest and generate an electrical image of the region. The sonar is configured to view a short range region of interest an output a sonar signal. The processor is in electrical communication with the camera and the sonar to receive the electrical image and the sonar signal. The processor analyzes the image and the sonar signal in order to determine the range of an object.

21. A method for determining range of a vehicle, the method comprising:
-
receiving an optical image of a first region of interest onto a camera;
receiving a sonar signal of a second region of interest onto a sonar;
generating an electrical image based on the optical image;
identifying a plurality of windows within the electrical image, each window corresponding to a predetermined physical size and a target range from the camera;
evaluating characteristics of a candidate object within each window signal to identify the vehicle;
evaluating the sonar signal to determine if objects are located within the second region of interest. - View Dependent Claims (22, 23, 24, 25, 26, 27, 28, 29, 30, 31, 32, 33, 34, 35, 36, 37, 38, 39, 40, 41, 42, 43, 44, 45, 46, 47, 48, 49, 50)
