Abstract
There is provided a vehicle drive control system that feels less unnatural and that enables an improvement in safety performance. A vehicle motion control system capable of independently controlling a driving force and a braking force of four wheels comprises: a first mode (G-Vectoring control) in which substantially the same driving force and braking force are generated with respect to left and right wheels among the four wheels based on a longitudinal acceleration/deceleration control command that is coordinated with the vehicle's lateral motion; and a second mode (sideslip prevention control) in which different driving forces and braking forces are generated with respect to the left and right wheels among the four wheels based on a target yaw moment derived from the vehicle's sideslip information, wherein the first mode is selected when the target yaw moment is equal to or less than a pre-defined threshold, and the second mode is selected when the target yaw moment is greater than the threshold.
