Abstract
A system for determining the potential for a possible cut-in situation by a cut-in vehicle on a subject vehicle. The subject vehicle may employ various devices, such as cameras, sensors, wireless communications systems, map data bases, navigational systems, etc., for detecting the cut-in vehicle, the possible movement of the cut-in vehicle, merge signs and other factors. The system can use this information in combination with collision avoidance systems or adaptive cruise control systems to take preventative action in the event of a potential cut-in situation.
Claims17
A system for determining a potential cut-in situation of a subject vehicle by a cut-in vehicle, said system comprising:
- a camera mounted to a forward portion of the subject vehicle, said camera having a field-of-view for detecting turn signal activity on the cut-in vehicle when the cut-in vehicle is adjacent to and/or forward of the subject vehicle;
- and
- a processor responsive to a signal from the camera indicative of the turn signal activity, said processor determining a potential cut-in situation and taking a predetermined action to help avoid a possible collision between the subject vehicle and the cut-in vehicle if the cut-in vehicle does cut in front of the subject vehicle.
A system for determining a potential cut-in situation of a subject vehicle by a cut-in vehicle, said system comprising:
- a detector mounted to a forward portion of the subject vehicle, said detector having a field-of-view for detecting whether the cut-in vehicle is crossing a center line when the cut-in vehicle is adjacent to and/or forward of the subject vehicle;
- a processor responsive to a signal from the detector indicative of the center line cross-over, said processor determining a potential cut-in situation and taking a predetermined action to help avoid a possible collision between the subject vehicle and the cut-in vehicle if the cut-in vehicle does cut in front of the subject vehicle and
- a sensor mounted to a forward portion of the subject vehicle, said sensor detecting vehicles in front of the subject vehicle said processor providing sensor fusion and merging in of the same vehicles detected by the sensor and the detector.
A system for determining a potential cut-in situation of a subject vehicle by a cut-in vehicle, said system comprising:
- at least one detection device for detecting the cut-in vehicle when the cut-in vehicle is adjacent to and/or forward of the subject vehicle, wherein the at least one detection device also detects lane ending signs or merge signs;
- and
- a processor responsive to a signal from the at least one detection device indicative of the location of the cut-in vehicle and the signs, said processor determining a potential cut-in situation and taking a predetermine action to help avoid a possible collision between the subject vehicle and the cut-in vehicle if the cut-in vehicle does cut in front of the subject vehicle.
