Abstract
A vehicle turning control device mounted on a vehicle includes a control device that calculates a control yaw moment for increasing turning performance of the vehicle and uses a yaw moment generation device to generate the control yaw moment. A limit control yaw moment, which is an upper limit of an allowable range of the control yaw moment in which the vehicle does not spin, is a function of a lateral jerk equivalent and decreases as the lateral jerk equivalent increases. The control device calculates the limit control yaw moment based on the lateral jerk equivalent and the function, updates a hold control yaw moment with a latest value of the limit control yaw moment when the latest value is less than the hold control yaw moment, and determines the control yaw moment so as not to exceed the hold control yaw moment.
