Zusammenfassung:	A driver assistance system for a motor vehicle monitors approaching objects around the vehicle in order to take a driver assistance action in response to a predicted impact with an approaching object according to a time-to-impact threshold. the time-to-impact threshold includes a nominal or default value that is adjusted according to several different measures of vehicle and driving conditions. Respective offsets determined by a load monitor, a braking monitor, and a steering monitor are added to the threshold in response to measured vehicle performance parameters being different from expected values. The driver assistance action may be a perceptible warning for a forward collision warning system, a speed reduction in an adaptive cruise control system, or a braking action in a brake-steer system.
