Abstract
Disclosed are a backlash vibration reduction apparatus and method capable of sufficiently performing gear alignment even when torque is increased while a vehicle is driven within a low torque range, thereby minimizing rough vibration due to backlash. The backlash vibration reduction apparatus includes a correction determination unit configured to determine whether it is necessary to correct a torque gradient to be applied for an increase to target torque in the state in which the current torque of a vehicle is retained within a predetermined low torque range and a torque gradient correction unit configured to determine a corrected torque gradient in which a torque increase rate per hour is reduced and a torque increase time period is extended by multiplying a correction factor by a first torque gradient as a torque gradient that increases the current torque upon determining that it is necessary to correct the torque gradient.
