摘要： A method of controlling driving of a vehicle using an in-wheel system includes: calculating a time to collision (TTC) by dividing a distance between the vehicle and an obstacle located in front of the vehicle by relative velocity; determining whether the vehicle enters a braking avoidance section, based on the calculated TTC; and generating, by a motor mounted in each wheel, braking force of a brake by an amount of shortage of braking force of the brake compared with a demanded braking force if the vehicle enters the braking avoidance section.

摘要： A device and a method for improving a turning motion of a vehicle may improve turning stability by cooperative control of an electric motor and the electronic controlled suspension (ECS) and improve behavior stability by optimizing a pitch/roll behavior by allowing realization of a target yaw moment required to improve turning characteristic of the vehicle to be reinforced by not only a yaw moment directly generated by a braking torque or a driving torque of the electric motor, but also a yaw moment indirectly generated by a load movement caused by controlling a damping force of the electronic controlled suspension (ECS).

摘要： An apparatus for improving turning performance of a vehicle includes: a turning characteristic detection module configured to detect a turning situation based on vehicle information obtained from at least one sensor and to calculate a required driving force to be implemented in the vehicle for a turning motion; a driving force estimation module configured to estimate a limited driving force applicable to a drive wheel; and a turning characteristic control module configured to control and apply a braking force corresponding to a difference between the required driving force and the limited driving force to a motor to inhibit a wheel slip, when the required driving force is greater than the limited driving force.
