FIELD: transportation.
SUBSTANCE: disclosed is a driver assistance system for a motor vehicle, which monitors approaching objects around the vehicle and performs a driver assistance procedure in response to a predicted impact with an approaching object according to a time-to-impact threshold. Time-to-impact threshold includes a nominal or default value that is adjusted according to several measured parameters of vehicle and driving conditions. Respective offsets determined by a load monitor, a braking monitor, and a steering monitor are added to the threshold if measured vehicle performance parameters are different from expected values. Driver assistance procedure 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.
EFFECT: safer movement.
