Arrangement for mitigating a forward collision between a host vehicle and an oncoming vehicle, the host vehicle having one or more sensors arranged to monitor a road ahead of the host vehicle and a braking system connected to wheel brakes (6, 7) thereof, said arrangement comprises: a vehicle forward collision threat evaluation system arranged to: utilize the one or more sensors to establish the presence of an oncoming vehicle and estimate parameters such as the distance between the oncoming vehicle and the host vehicle, lateral and longitudinal velocity of the oncoming vehicle, relative longitudinal velocity between the host vehicle and the oncoming road vehicle and lateral and longitudinal acceleration of the oncoming vehicle; utilize the estimated parameters to predict a future path of the oncoming vehicle; utilize host vehicle parameters to predict a future path of the host vehicle; said arrangement characterized in that, said vehicle forward collision threat evaluation system is arranged to assess the predicted future paths of the oncoming vehicle and of the host vehicle to determine if a forward collision between the host vehicle and the oncoming vehicle is likely unavoidable assuming full freedom for performing avoidance manoeuvres for both the host vehicle and the oncoming vehicle in the prediction of the respective future paths of the host vehicle and the oncoming vehicle using an assessment of best case scenarios for the host vehicle 's and the oncoming vehicle's possibilities to avoid the accident, such that a forward collision is determined as likely unavoidable if the considered best case scenarios for both the host vehicle and the oncoming vehicle are predicted to end in a forward collision, and said arrangement further comprising a forward collision mitigation brake controller arranged to control the braking system to control the wheel brakes (6, 7) of the host vehicle to reduce a relative longitudinal velocity between the host vehicle and the oncoming vehicle at a predicted collision instant only if determined that a forward collision between the host vehicle and the oncoming vehicle is likely unavoidable at a determined relative longitudinal velocity above a first threshold, said first threshold being suitable selected such that passive safety systems of said host vehicle are adapted to handle a forward collision at relative longitudinal velocities below said first threshold. utilize the one or more sensors to establish the presence of an oncoming vehicle and estimate parameters such as the distance between the oncoming vehicle and the host vehicle, lateral and longitudinal velocity of the oncoming vehicle, relative longitudinal velocity between the host vehicle and the oncoming road vehicle and lateral and longitudinal acceleration of the oncoming vehicle; utilize the estimated parameters to predict a future path of the oncoming vehicle; utilize host vehicle parameters to predict a future path of the host vehicle; said arrangement characterized in that, said vehicle forward collision threat evaluation system is arranged to assess the predicted future paths of the oncoming vehicle and of the host vehicle to determine if a forward collision between the host vehicle and the oncoming vehicle is likely unavoidable assuming full freedom for performing avoidance manoeuvres for both the host vehicle and the oncoming vehicle in the prediction of the respective future paths of the host vehicle and the oncoming vehicle using an assessment of best case scenarios for the host vehicle 's and the oncoming vehicle's possibilities to avoid the accident, such that a forward collision is determined as likely unavoidable if the considered best case scenarios for both the host vehicle and the oncoming vehicle are predicted to end in a forward collision, and said arrangement further comprising a forward collision mitigation brake controller arranged to control the braking system to control the wheel brakes (6, 7) of the host vehicle to reduce a relative longitudinal velocity between the host vehicle and the oncoming vehicle at a predicted collision instant only if determined that a forward collision between the host vehicle and the oncoming vehicle is likely unavoidable at a determined relative longitudinal velocity above a first threshold, said first threshold being suitable selected such that passive safety systems of said host vehicle are adapted to handle a forward collision at relative longitudinal velocities below said first threshold.
