A turning behavior control device for a vehicle includes a yaw rate detector, a front wheel suspension, a rear wheel suspension, a brake device, a hydraulic pressure supplier, and a travel controller. The left and right front wheels of the vehicle are steered wheels and drive wheels. The travel controller includes a deviation value calculator configured to calculate a deviation between a standard yaw rate for determining a degree of understeer during turning of the vehicle and a yaw rate detected by the yaw rate detector, and a braking force controller configured to output, to the hydraulic pressure supplier, a first signal for applying braking forces to left and right front wheels in addition to a turning inner rear wheel when it is determined that the deviation calculated by the deviation value calculator exceeds a predetermined deviation reference value.

Turning behavior control device for vehicle

A turning behavior control device for a vehicle includes a yaw rate detection unit, a brake unit, a drive source, and a travel control unit. The travel control unit includes a deviation value calculation unit that calculates a deviation between a reference yaw rate for determining the degree of understeer during turning of the vehicle and an actual yaw rate detected by the yaw rate detection unit, a braking force control unit that outputs, to the brake unit, a first signal for applying the braking force to a turning inner-side rear wheel or a turning inner-side front wheel when determining that the deviation exceeds a predetermined deviation reference value, and a driving force control unit that outputs, to the drive source, a signal for applying a driving force to a turning outer-side rear wheel or a turning outer-side front wheel when the braking force control unit outputs the signal.
