<P>PROBLEM TO BE SOLVED: To provide a driving force distribution controlling device capable of estimating a limit of cornering force by high responsivity at the time of turning with steering operation, and informing a driver that a limit of vehicular behavior is close with good responsivity. <P>SOLUTION: A vehicle uses one of front and rear wheels as a main driving wheel and the other as a sub driving wheel, and is provided with a driving force distribution controlling means controlling driving force distribution of the front and rear wheels. The vehicle comprises a steering operation amount detecting means (a steering angle sensor 7) detecting the steering operation amount of a driver, and a steering operation amount limit determination value setting means (a step S2) setting a steering operation amount limit determination value in a area near a cornering force limit by a lateral slipping angle of the front wheel. The driving force distribution controlling means carries out feed-forward control changing driving force transmitted to the sub driving wheel in a step-by-step manner when the steering operation amount of the driver exceeds the steering operation amount limit determination value. <P>COPYRIGHT: (C)2006,JPO&NCIPI |
