Title
(EN) Systems and Methods for Providing a Vehicle with a Torque Vectored K-Turn Mode
Abstract
(EN)

Systems and methods are provided herein for operating a vehicle in a K-turn mode. The K-turn mode is engaged in response to determining that an amount that at least one of the front wheels of the vehicle is turned exceeds a turn threshold. While operating in the K-turn mode, forward torque is provided to the front wheels of the vehicle. Further, backward torque is provided to the rear wheels of the vehicle. Yet further, the rear wheels of the vehicle remain substantially in static contact with a ground while the front wheels slip in relation to the ground.
