The invention relates to a control device and a control method for vehicle. An ECU executes a program including a step (S100) of detecting the distance to an object, a step (S104) of switching over, when a collision is predicted (YES in S102), a switchover damper from an inside-air circulation to an outside-air circulation, a step (S106) of controlling a power window device to lower door glass, astep (S112) of turning off an SMR when the collision is detected (YES in S108), and a step (S114) of controlling the power window device to fully open the door glass.
