<P>PROBLEM TO BE SOLVED: To provide a control device for distribution of right and left wheels driving forces which can give such a stationary control component as quickening a leading-up response of a turning behavior in an turning initial stage. <P>SOLUTION: A rear wheel driving force difference determining gain Gain multiplied by a basic right-and-left-wheel driving force difference stationary control computation value for a vehicle turning behavior required stationarily by a driver is made to be larger than 1 in the turning initial stage where a lateral acceleration Gy is set to be less than a turning initial determination value Gys, as shown in (a), and set to A getting large along with reduction of the lateral acceleration Gy. A final rear wheel driving force difference ΔTcLR obtained by multiplying, with a feedback control coefficient, a right-and-left-wheel driving force difference that is the sum value of a final right-and-left-wheel driving force difference stationary control component obtained by multiplying the basic right-and-left-wheel driving force difference stationary control computation value with the rear wheel driving force difference determining gain Gain=A, and a right-and-left-wheel driving force difference transition control component, is thereby increased in the turning initial stage (lateral acceleration Gy<Gye), as shown as a solid line in (b), to enhance the initial turning response. <P>COPYRIGHT: (C)2012,JPO&INPIT |
