DCFirst Claim
1. A vision system for a vehicle, said vision system comprising:
- at least one imaging sensor having a forward field of view with respect to a forward direction of travel of a vehicle equipped with said vision system, wherein said at least one imaging sensor comprises a lens and a CMOS imaging array comprising a two-dimensional array of photosensing elements, and wherein said at least one imaging sensor captures image data representative of objects present in said forward field of view;
at least one register operable to access photosensing elements of said array of photosensing elements;
wherein said array of photosensing elements comprises a plurality of sub-arrays, said sub-arrays each having at least three neighboring photosensing elements;
wherein at least one photosensing element of each sub-array comprises a red light sensitive photosensing element and at least one other photosensing element of each sub-array comprises a white light sensitive photosensing element;
a control responsive to said at least one imaging sensor;
wherein said control processes image data captured by said at least one imaging sensor to determine an object present in said forward field of view;
wherein said control processes image data captured by said at least one imaging sensor to determine a distance between the equipped vehicle and the object determined present in said forward field of view; and
wherein said control discerns if the determined object is an oncoming vehicle or a leading vehicle at least in part in response to rate of approach of the determined object to the equipped vehicle.

Abstract
A vision system for a vehicle includes at least one imaging sensor having a forward field of view with respect to a forward direction of travel of the vehicle. The imaging sensor captures image data representative of objects present in the forward field of view. A control is responsive to the imaging sensor and processes image data captured by the imaging sensor to determine an object present in the forward field of view. The control processes image data to determine a distance between the vehicle and the object determined present in the forward field of view. The control may determine the distance between the vehicle and the determined object at least in part in response to at least one of (i) size of the determined object, (ii) position of the determined object, (iii) light intensity of the determined object, and (iv) rate of approach of the determined object.
