Abstract
A pre-crash control device includes target information acquisition units and an electric control unit configured to update a recognized position based on an acquired position each time target information is newly acquired, to estimate a moving direction based on history of the recognized position, to determine whether a collision probability is high based on the recognized position and the moving direction, and to perform pre-crash control if it is determined that the collision probability is high and a time to collision becomes equal to or smaller than a threshold execution time. The electric control unit is configured to update the recognized position based on a currently predicted position and on the acquired position and to update the recognized position to the acquired position when the time to collision becomes equal to or smaller than a first threshold switching time.
