<P>PROBLEM TO BE SOLVED: To prevent control to increase traveling stability from being hindered in a control device for a vehicle for increasing the traveling stability of a vehicle due to the distribution of a driving power or a braking power. Ž<P>SOLUTION: A target front wheel lateral force setting part 12 included in a microcomputer 10 determines a target front wheel lateral force Fft based on a steering angle θ and a speed V and a front wheel load Ffz, and an FB control arithmetic part 16 calculates a command value Dc, and applies it to a distribution device driving circuit 20 so that a real front wheel lateral force Ffy of the vehicle can be matched with this. A rear wheel longitudinal force Frx to be generated from this is detected by a rear wheel longitudinal force sensor 6, and a suppression quantity calculation part 38 calculates suppression quantity As based on this value, and a subtraction unit 34 subtracts this from the target steering angle At. A steering rate calculation part 36 converts this into a steering ratio, and applies it to a steering ratio varying device driving circuit 40. Therefore, it is possible to suppress the steering of the vehicle, and prevent the front wheel from horizontally sliding due to the distribution. Thus, control to increase traveling stability, and the like are not hindered. Ž<P>COPYRIGHT: (C)2009,JPO&INPIT Ž |
