A vehicle safety system includes an actuatable restraint for helping to protect a vehicle occupant and a controller for controlling actuation of the actuatable restraint in response to a vehicle rollover event. The controller is configured to execute a discrimination algorithm comprising at least one classification metric that utilizes at least one of vehicle pitch rate (P_RATE) and vehicle roll acceleration (D_RATE) to discriminate at least one of a ramp rollover event and a soil rollover event from an embankment rollover event. The discrimination algorithm determines a classification of the vehicle rollover event as one of a ramp rollover event, a soil rollover event, and an embankment rollover event. The controller is also configured to select a deployment threshold for deploying the actuatable restraint. The deployment threshold corresponds to the classification of the vehicle rollover event.
