Summary:PURPOSE:To reduce the number of toe angle control means by controlling the toe angle of rear wheel through controlling of tire angle of one of right and left rear wheels, obtaining thereafter an integration angle indicating the advance direction of a vehicle from the toe angle after the rear wheel is controlled, and performing toe angle control of front wheel based on this integration angle. CONSTITUTION:In controlling a toe angle, firstly, the tire angle of each wheel is measured by a toe angle measuring unit 4 so as to obtain the integration angle of rear wheel. Next, based on the virtual line of integration angle of rear wheel, the toe angle of front wheel which is the tire angle obtained by eliminating influence of the steering angle of front wheel on this virtual line, and also, the deviation angle of integration angle of front wheel. It is judged whether the toe in amount converted from the toe angle of each wheel and the deviation amount is in a set area or not, and according to the judgement of results, a toe angle controller 5 is controlled.
