Abstract
An on-vehicle apparatus is provided to reduce damage from collisions. In the apparatus, an object located in a field in a travel direction of a vehicle is detected and a time to collision (TTC) is detected. A controller performs automatic intervention braking in the vehicle when it determined that the time to collision is equal to or shorter than a first threshold time. Further, when it determined that the time to collision is equal to or shorter than a second threshold time shorter than the first threshold time and meets a preset actuation condition, a protection controller makes a protection device active for vehicle protection. A collision speed is also estimated based on an deceleration of the vehicle caused by the automatic intervention braking. The preset actuation condition is a condition that the estimated collision speed is equal to or higher than a preset threshold speeds.
