METHOD FOR CONTROLLING AXLE LOAD DISTRIBUTION OF A VEHICLE
A method for controlling axle load distribution of a heavy-duty vehicle during a maneuver, wherein the heavy-duty vehicle comprises a number of wheel axles and one or more motion support devices arranged to adjust a relative axle load of one or more wheel axles of the number of wheel axles, the method comprising obtaining a vehicle model and a tire model, wherein the vehicle model and the tire model are jointly configured to predict a tire scrubbing force in dependence of a vehicle state comprising a relative axle load distribution during the maneuver, determining a nominal tire scrubbing force for a current relative axle load distribution, determining an improved relative axle load distribution maneuver associated with a reduced tire scrubbing force compared to the nominal tire scrubbing force, and controlling the one or more motion support devices to provide the improved relative axle load distribution during the maneuver.
Apparatus for controlling turning of vehicle, system having the same, and method thereof
An apparatus for controlling turning of a vehicle, a system having the same, and a method thereof are provided. The vehicle turning control apparatus include a processor to perform a control operation to determine whether a present situation is a normal turning situation based on steering angle information and wheel speed information of the vehicle, and operate an electronic limited slip differential (eLSD) by making an inner wheel slip based on a turning direction when an operation of the eLSD is failed in the normal turning situation; and a storage to store data obtained by the processor and an algorithm executed by the processor.

SYSTEM FOR MITIGATING VEHICLE SWAY
A vehicle includes friction brakes, an axle, and a controller. The axle has an electronic limited-slip differential that includes a variable torque capacity lockup clutch. The controller is programmed to, in response to a difference between desired and actual yaw rates exceeding a first threshold, increase the torque of the lockup clutch to decrease the difference between the desired and actual yaw rates. The controller is further programmed to, in response the difference between desired and actual yaw rates exceeding a second threshold that is greater than the first threshold, increase the torque of the friction brakes to decrease the difference between the desired and actual yaw rates.
Hybrid vehicle and driving control method therefor
A driving control method of a hybrid vehicle is provided. The method includes when a specific zone related to discharge of exhaust gas is detected ahead on a path, determining whether a current state of charge (SoC) of a battery is greater than a first value. When the current SoC is greater than the first value, driving in a first mode for charging the battery in power of an engine in a first section disposed before entrance into the specific zone. Upon entering a second section corresponding to the specific zone, a current mode into a second mode for driving using power of a motor only is converted, battery consumption is reduced using at least one step along with a change in the current SoC in the second section.
DRIVING FORCE CONTROL SYSTEM FOR VEHICLE
A driving force control system for a vehicle is provided to control a torque vectoring device is provided. A controller is configured to bring the torque vectoring device into a preparatory state in which the differential torque and the differential limit torque are equalized to each other when shifting the operating mode between the differential mode and the differential limit mode, and to shift the operating mode of the torque vectoring device by gradually reducing a difference between the differential torque and the differential limit torque.
Method and Device for Controlling Vehicle Motion and Vehicle Equipped with Same
The purpose of the present invention is to provide a device and method for controlling vehicle motion and a vehicle equipped with the device, such that driving force and/or braking force is properly distributed between front wheels and rear wheels so that steering characteristics are made suitable and controllability and stability improve. This device comprises a means for controlling braking and/or driving force distribution between the front wheels and rear wheels of a vehicle such that when the absolute value of lateral acceleration of the vehicle increases, the distribution to the front wheels is made smaller, and when the absolute value of lateral acceleration of the vehicle decreases, the distribution to the front wheels is made larger.

VEHICLE MOTION CONTROL USING TORQUE VECTORING WITH CONSIDERATION OF DRIVER INTENT AND LOAD TRANSFER
A method includes identifying an actual path and a desired path for a vehicle, where the actual path represents an expected path for the vehicle based on current operation of the vehicle and the desired path represents an estimated path that a driver of the vehicle wants to follow. The method also includes identifying one or more errors between the actual path and the desired path. The method further includes determining how to apply torque vectoring to cause the vehicle to more closely follow the desired path based on the one or more errors. In addition, the method includes applying the torque vectoring to create lateral movement of the vehicle during travel.
