Abstract: A control system for reducing drive shaft vibration of an environment-friendly vehicle includes: a drive shaft speed extraction unit that extracts an actual drive shaft speed of a motor and extracts a drive shaft speed from which a forced vibration component that is to be transferred by an engine to the drive shaft is removed; a model speed computation unit that calculates a model speed of the drive shaft; a free vibration computation unit that computes a free vibration component on the basis of deviation between the drive shaft speed and the calculated model speed; and a first torque computation unit that calculates, from the free vibration component, a free vibration reduction compensation torque for reducing the drive shaft vibration.

Abstract: A method of controlling vibration reduction of a vehicle is capable of efficiently reducing vibration occurring when entering a P range on a ramp. The method includes: when an input to a parking range is received, determining whether or not a predetermined condition for entering a vibration reduction control mode is satisfied; when the entering condition is satisfied, calculating a motor torque for reducing vibration due to backlash by using the driving information; controlling a driving motor so as to output the calculated motor torque; controlling the parking device such that the parking range is engaged; determining whether or not a brake is released; and if the brake is released, reducing a motor torque output by the driving motor so that vibration due to the backlash is reduced.

Abstract: An apparatus for compensating for a position error of a resolver has a controller which is configured to: receive position information of a rotor of a motor, which is detected by the resolver, to measure a first position error, convert the first position error to a second position error at an electrical angular velocity of 0, and to store the second position error; receive a current electrical angular velocity and the second position error, convert the second position error to a third position error at the current electrical angular velocity, and compensate for the third position error; and perform determination of false position error compensation when a magnitude of a ripple at an electrical angular velocity, which is measured after the third position error has been compensated for, is equal to or greater than a reference magnitude.

Abstract: A dual inverter control method is capable of improving power efficiency of an inverter and a motor by controlling a dual inverter through 6-step control to apply a voltage to the motor in a motor driving system using the dual inverter. The dual inverter control method for controlling first and second inverters having output terminals commonly connected to a motor includes comparing all voltage commands for driving the motor with the magnitude of a DC voltage commonly applied to the first and second inverters; and generating a first voltage command with respect to an output of the first inverter and a second voltage command with respect to an output of the second inverter by selectively applying high gain over voltage modulation (HOVM) depending on a comparison result.

Abstract: A method for measuring an offset of a resolver is arranged so as to frequently measure and correct the offset of the resolver by actively performing zero current control of a motor. The method includes steps of: determining whether a torque command value of the motor and a magnetic flux value or reverse magnetic flux value of the motor respectively fall within a first range and a second range, which have been set in advance; controlling the motor to perform zero current control for a preset time period when the torque command value of the motor falls within the first range and the magnetic flux value or reverse magnetic flux value of the motor falls within the second range; and measuring the offset of the resolver for the preset time period.
