Abstract
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.
Claims18
An apparatus for controlling turning of a vehicle, the apparatus comprising:
- a processor configured 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, to determine an inner wheel based on a turning direction of the vehicle, and to operate an electronic limited slip differential (eLSD) by making an inner wheel slip when an operation of the eLSD is failed in the normal turning situation;
- and
- a storage configured to store data obtained by the processor and an algorithm executed by the processor,
- wherein the processor is further configured to make the inner wheel slip by generating normal force through an active suspension to shift a load of the vehicle outward from the turning direction.
A vehicle system comprising:
- an electronic limited slip differential (eLSD) to transmit driving torque to an outer wheel, which is determined based on a turning direction of the vehicle, when a vehicle turns;
- an active suspension to control normal force applied to an inner wheel and the outer wheel;
- and
- a processor configured 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 a vehicle, to determine an inner wheel based on the turning direction, and to operate the eLSD by making an inner wheel slip through the active suspension when an operation of the eLSD is failed in the normal turning situation.
A method of controlling turning of a vehicle, the method comprising:
- determining whether a present situation is a normal turning situation based on steering angle information and wheel speed information of the vehicle;
- determining whether an operation of an electronic limited slip differential (eLSD) is failed in the normal turning situation;
- determining an inner wheel based on a turning direction of the vehicle;
- and
- performing a control operation to operate the eLSD by making an inner wheel slip when the operation of the eLSD is failed in the normal turning situation,
- wherein the performing a control operation to operate the eLSD includes
- making the inner wheel slip by controlling normal force applied to each of an outer wheel and the inner wheel of the vehicle to shift a load of the vehicle outward from the turning direction.
