Vehicle motion control device
This device is applied to a vehicle having a dual circuit brake conduit (so-called X-conduit) comprising a circuit for a front-right wheel and a rear-left wheel and a circuit for a front-left wheel and a rear-right wheel. This device obtains basic control volume Gb based upon a vehicle body speed and a road friction coefficient during an understeer restraining control or oversteer restraining control, and obtains yaw control volume Gd based upon a deviation between a target yaw rate and actual yaw rate. Then, it exerts braking force according to the basic control volume Gb respectively on two wheels of one circuit to which front wheel at the outer side of the turning direction and the rear wheel at the inner side of the turning direction belong, to thereby decelerate the vehicle, and further exerts braking force according to the yaw control volume Gd on either one wheel of the same circuit, thereby producing a yawing moment for making the turning state close to the target state.
