measuring host vehicle dynamic conditions;
predicting a host vehicle trajectory in response to the host vehicle dynamic conditions;
determining an azimuth for the target object;
monitoring the brake system status;
determining an actuation value as a function of the target range signal, the target relative velocity signal, the host vehicle trajectory, brake system and the target azimuth; and
activating a countermeasure in response to said actuation value.

Abstract
A control system for an automotive vehicle (50) has a radar or lidar system (22) used to generate a remote object signal. A vision system (26) confirms the presence of the target object in the detection zone. A controller (12) is coupled to the remote object sensor and a vehicle dynamics sensor and the brake system. The controller predicts a host vehicle trajectory in response to the host vehicle dynamic signal, determines an azimuth angle for the target object, determines an actuation value in response to the target range signal, the target relative velocity signal, the host vehicle trajectory, host vehicle brake system status and the target azimuth angle. The controller (12) activates a countermeasure in response to the actuation value.
