While the cameras used by an ADAS system may provide an unobstructed view of the surroundings, the driver's view may be obstructed. For example, the vehicle's design may impede the driver's view. The images captured by the ADAS system can be analyzed to identify objects located in areas where the driver's view is obstructed. If the driver's view of the object is obstructed, the ADAS may behave differently than it would if the driver could see the object. For example, the ADAS system may initiate automatic braking to more quickly avoid a collision with an object if the driver cannot see it due to an obstruction.

While the cameras used by an ADAS system may provide an unobstructed view of the surroundings, a driver's view may be obstructed. For example, a driver's view could be obstructed by the construction of the vehicle. Analysis may be conducted on the images collected by the ADAS system to identify objects that are in areas where the driver's view is occluded. If the driver's view of the object is occluded, the ADAS may behave differently than it otherwise would if the driver was aware of the object. For example, the ADAS system may apply automatic braking to avoid hitting an object more quickly if the driver cannot see it due to an occlusion.

The driver assistance system can further comprise a driver monitoring system determining a driver awareness. The driver monitoring system can comprise a camera observing the driver. According to an embodiment, based on images captured from the camera, a gaze direction of the driver can be determined. The gaze direction can be evaluated to determine whether the gaze direction is directed at an object in the vehicle's surroundings. If the object is within the driver's trajectory, the driver assistance system can recognize that the driver is aware of the object. Thus, the driver assistance system can delay an automatic braking that would otherwise be triggered due to the object.
