Patent ID: 8660769

Claim:
A vehicle motion control system which is to be installed on a vehicle having a single front wheel, a right wheel and a left wheel, the single front wheel being disposed in a widthwise center of a front portion of the vehicle, the right and left wheels being disposed in respective right and left portions of the vehicle and located on a rear side of the single front wheel, said control system being configured to control motion of the vehicle, said control system comprising: a front-wheel steering device configured to steer the front wheel; a braking device configured to apply a braking force to each of the front wheel and right and left wheels; and a controlling device configured to execute control of the vehicle, said controlling device including a braking-force controlling portion configured to control the braking force that is to be applied to each of the front wheel and right and left wheels, by controlling said braking device in accordance with an operation applied to a brake operating member; wherein said braking-force controlling portion includes a slip-management controlling portion configured, when the vehicle is to be braked in a direction-change situation that there is a change of a heading direction of the vehicle toward a particular direction due to slip of at least one of the right and left wheels and/or when the vehicle is to be braked in a direction-change risk situation that there is a risk of the change of the heading direction of the vehicle toward the particular direction, to execute a slip managing control for managing the change of the heading direction of the vehicle, such that a magnitude of the braking force applied to the front wheel varies depending on a direction of turning of the front wheel, even with a same operation being applied to the brake operating member, and wherein said slip-management controlling portion of said braking-force controlling portion is configured, in execution of the slip managing control, to suppress the change of the heading direction of the vehicle, by controlling the braking force applied to the front wheel, such that the braking force applied to the front wheel is made larger when the front wheel is turned in a direction same as the particular direction, than when the front wheel is turned in a direction opposite to the particular direction.
