Driver assistance system for vehicle

A driver assistance system for a vehicle, said driver assistance system comprising:

• an imaging device having a field of view forward of a vehicle equipped with said driver assistance system and in a direction of travel of the equipped vehicle, wherein said imaging device is operable to capture image data;
• an image processor operable to process image data captured by said imaging device;
• speed sensing for determining a speed of the equipped vehicle;
• an adaptive speed control system for establishing a speed of the equipped vehicle at least in part responsive to a cruise control speed setting of said adaptive speed control system;
• wherein said processing of captured image data by said image processor comprises recognition of a sign;
• wherein said driver assistance system determines a speed limit for the road along which the equipped vehicle is traveling based at least in part on processing image data;
• wherein said adaptive speed control system at least one of (a) adjusts the cruise control speed setting responsive to a speed limit for the road along which the equipped vehicle is traveling as determined at least in part by processing image data by said image processor, (b) reduces the current speed of the equipped vehicle responsive to recognition of a warning sign at least in part by processing image data by said image processor, and (c) reduces the current speed of the equipped vehicle responsive to detection of a curve in the road ahead of the equipped vehicle at least in part by processing image data by said image processor.

• wherein said adaptive speed control system adjusts the speed of the equipped vehicle responsive to recognition of a warning sign at least in part by said processing of image data by said image processor;
• and
• wherein said adaptive speed control system reduces the speed of the equipped vehicle to a speed level indicated on the recognized warning sign.

A driver assistance system for a vehicle, said driver assistance system comprising:

• an imaging device having a field of view forward of a vehicle equipped with said driver assistance system and in a direction of travel of the equipped vehicle, wherein said imaging device is operable to capture image data;
• an image processor operable to process image data captured by said imaging device;
• wherein said processing of image data by said image processor comprises at least one of (a) recognition of a sign and (b) recognition of characters on a sign;
• speed sensing for determining a speed of the equipped vehicle;
• an adaptive speed control system for establishing a speed of the equipped vehicle at least in part responsive to cruise control speed setting of said adaptive speed control system;
• wherein said adaptive speed control system reduces the speed of the equipped vehicle at least responsive to recognition of a warning sign indicative of a curve in the road ahead of the equipped vehicle at least in part by said processing of image data by said image processor, and wherein said adaptive speed control system reduces the speed of the equipped vehicle responsive to detection of a curve in the road ahead of the equipped vehicle;
• and
• wherein the speed of equipped vehicle resumes said cruise control speed setting when the equipped vehicle is traveling along a straighter section of road after the curve in the road.
