ABSTRACT:
A vehicle has a safety system including at least one object sensor to detect a distance from an object in a path of the vehicle and the speed and acceleration of the object. The sensor data is input into a control to determine a desired braking judgment line and a steering judgment line between the vehicle and the object. The safety system then compares the vehicle and object acceleration. Following, the safety system calculates a judgment line between the object and the vehicle based upon equations for the determined scenario. The judgment line is then used to determine a warning distance and warn a vehicle operator.
