Title:
APPARATUS FOR IMPROVING STEERING SENSITIVITY OF VEHICLE
Document Type and Number:
WIPO Patent Application WO/2011/145410
Kind Code:
A1
Abstract:
Disclosed is an apparatus for improving the steering sensitivity of a vehicle, in which a motor torque increase correction operation during a setting time period (TM1s) and a motor torque decrease correction operation during a setting time period (TM2s) are sequentially performed while the vehicle is being steered after t1, and a wheel driving force is repeatedly increased or decreased in a manner such that a driver cannot perceive the acceleration or deceleration of the vehicle. The repeated increase or decrease in the wheel driving force causes an increase or decrease in steering force which is exhibited as an amount of thrust increase or decrease of a steering rack. When the steering force is repeatedly increased or decreased, since the driver may strongly sense a large steering force (during the increase) as a whole, the intensity of the steering force sensed by the driver can be appropriately adjusted merely by the settings for the motor torque increase time period (TM1s) and the motor torque decrease time period (TM2s), and steering sensitivity can be improved in such a way that the driver can feel a sense of security and a sense of unity with the vehicle.
