Abstract
method of controlling torque of a vehicle driving device is provided. The method includes estimating speed of a driving system of a vehicle from vehicle driving information collected from the vehicle and calculating speed difference between actually measured speed of the driving system and the estimated speed of the driving system. A nominal rate limit value is determined according to the vehicle driving information and a required real-time rate correction amount is determined according to the calculated speed difference. A torque command variation is determined based on the determined nominal rate limit value and the determined required real-time rate correction amount. A torque command after correction in a previous control period is corrected by the determined torque command variation to determine a torque command after correction in a current control period.
