PROBLEM TO BE SOLVED: To improve traveling fuel economy when a tire internal pressure is low. SOLUTION: This device is provided with: parts 42, 43 for calculating tire internal pressure average inputted by front and rear wheel tire internal pressure signals detected by tire internal pressure sensors 20, 21 of the front and rear wheels; a brake distribution change setting part 45 for setting front and rear brake force distribution according to a difference between the front and rear wheels of a tire internal pressure average value; a brake front and back distribution setting part 46 for setting a normal front and rear brake distribution according to a brake pressure; a gain correction part 47 for setting weighting of the brake force distribution set by the tire internal pressure and the normal brake distribution; and a brake front and rear distribution setting part 48 for setting the front and rear brake force distribution based on them. The lower internal pressure of each tire of the front and rear wheels is increased quickly by increasing the brake force, and the internal pressure of each tire of the front and rear wheels is made a proper value at an early stage from the start of traveling, so that a vehicle travels with less rolling resistance to improve traveling fuel economy.
