Turning behavior control device for vehicle

A turning behavior control device for a vehicle, the turning behavior control device comprising:

• a yaw rate detector configured to detect a yaw rate of the vehicle;
• a front wheel suspension having an anti-dive geometry;
• a rear wheel suspension having an anti-lift geometry;
• a brake device configured to independently apply a braking force to left and right front wheels of the vehicle and left and right rear wheels of the vehicle;
• a hydraulic pressure supplier configured to supply a brake hydraulic pressure to the brake device;
• and
• a travel controller, wherein the left and right front wheels are steered wheels and drive wheels,
• the travel controller comprises a memory that stores instructions and a processor configured to execute the instructions,
• the instructions cause the processor to perform:
• calculating a deviation between a standard yaw rate for determining a degree of understeer during turning of the vehicle and the yaw rate detected by the yaw rate detector;
• and
• when the calculated deviation exceeds a predetermined deviation reference value, executing a turning behavior control comprising:
• outputting, to the hydraulic pressure supplier, a first signal for applying braking forces to only three wheels including the left and right front wheels and to a turning inner rear wheel and excluding a turning outer rear wheel,
• the hydraulic pressure supplier is configured to, in response to receiving the first signal, supply the brake hydraulic pressure to the brake device, and
• in response to the brake hydraulic pressure being supplied to the brake device, the brake device applies the braking forces to only the three wheels including the left and right front wheels and the turning inner rear wheel and excluding the turning outer rear wheel,
• after expiration of a predetermined period of time, ending the turning behavior control.
