Abstract: A pre-collision control ECU performs a pre-collision control in order to preventing a collision between the own vehicle and the object when a control start condition is satisfied. The ECU acquires a velocity threshold Vsth corresponding to a region in which the own vehicle travels based on information to specify the region. When an allowance condition has been satisfied before a timing at which the control start condition is satisfied, the ECU performs the pre-collision control. When the allowance condition has not been satisfied before the timing, the ECU does not perform the pre-collision control. The allowance condition is a condition that an accelerator operation amount is equal to or greater than an operation amount threshold and a vehicle velocity is equal to or lower than the acquired velocity threshold.
