PROBLEM TO BE SOLVED: To provide a controller of a four wheel drive vehicle, which is mounted on the four wheel drive vehicle having a drive transmission capable of adjusting drive power to be transmitted to auxiliary driven wheels, and which can stabilize behavior of the vehicle when an obstacle ahead of the vehicle is detected.SOLUTION: There is provided a controller 6 for controlling a drive transmission 2, the controller being mounted on a four wheel drive vehicle 1 having: the drive transmission 2 capable of adjusting drive power to be transmitted to rear wheels 191, 192; and a collision prevention device 7 that generates braking force when there is a possibility of collision with an obstacle ahead of the vehicle. The controller comprises: receiving means 610 for receiving a signal that is transmitted by the collision prevention device 7 after detection of the obstacle; and collision avoiding control means 612 which determines drive power to be transmitted to the rear wheels 191, 192, and controls the drive transmission 2 so that the determined drive power is transmitted to the rear wheels 191, 192, when the receiving means 610 receives the signal of the collision prevention device 7 while the vehicle travels in a two wheel drive state where the drive power of an engine 11 is transmitted only to front wheels 181, 182.SELECTED DRAWING: Figure 1
