1. A method comprising:
determining a usable distance between a host vehicle and a moving object by at least:
detecting, via a detection system of the host vehicle, a current obstacle free distance in front of the host vehicle, wherein the current obstacle free distance is limited by a current position of the moving object and wherein the detection system includes at least one of:
a visual system that is additionally configured to determine a current velocity of the moving object,
a RADAR system that is additionally configured to determine the current velocity of the moving object, and
a LIDAR system that is additionally configured to determine the current velocity of the moving object;
estimating, via a processor of the host vehicle, an extension distance based on:
the current velocity of the moving object,
a predicted emergency braking distance of the moving object based on a predefined constant deceleration being applied to the moving object for a predetermined time period and a predefined jerk being applied to the moving object before and after the predetermined time period, the jerk being defined as a rate of change per time period of the deceleration of the moving object, and
a predicted emergency steering distance of the moving object; and
determining, via the processor, the usable distance based on the current obstacle free distance and the extension distance; and
activating or deactivating, based on the usable distance, at least one driver assistance system of the host vehicle.
