Vehicle Motion Control Device
First Claim
1. A vehicle motion control system capable of independently controlling a driving force and braking force of four wheels, the vehicle motion control system comprising:
- a first mode 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 target longitudinal acceleration/deceleration control command that is coordinated with a lateral motion of the vehicle; and
a second mode 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 sideslip information of the vehicle, whereinthe 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.

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 (FIG. 11).
