Abstract:
1. A gateway control apparatus for vehicles that enables data communication between electronic control units having different communication modes, the apparatus comprising: a receiver configured to receive vehicle state information from the electronic control units of a vehicle and a vehicle-to-vehicle distance from an intelligent cruise control unit, the vehicle state information including a vehicle velocity or a vehicle acceleration; a first memory configured to store the received vehicle state information; a calculation unit configured to calculate a relative velocity and a relative acceleration based on the received vehicle state information and configured to calculate a collision index using the relative velocity, the relative acceleration, and the vehicle-to-vehicle distance; a determination unit configured to determine whether the collision index exceeds a predetermined value; and a vehicle information management unit configured to determine an accident occurrence time point when it is determined that the collision index exceeds the predetermined value and configured to store pre-accident vehicle state information and post-accident vehicle state information obtained with reference to the accident occurrence time point in the first memory.
