Patent number: 9077266Abstract: An apparatus for controlling a vehicle provided with a motor includes a current command generator that determines first and second axes currents according to driving conditions, and a current controller that generates first and second axes voltages by using the first and second axes currents and feedback currents. An axis converter converts the first and second axes voltages into 3-phase voltages, 3-phase feedback currents into first and second axes feedback currents, and transmits the same to the current controller. A pulse width modulation (PWM) generator receives the 3-phase voltages and generates corresponding 3-phase signals, and a PWM inverter generates 3-phase currents and transmits the same to the axis converter. A motor is driven by the 3-phase currents. A resolver detects a phase of the motor and transmits the same to the current command generator and the axis converter. A resolver offset determining unit calculates a resolver offset value.Type: GrantFiled: December 30, 2013Date of Patent: July 7, 2015Assignee: HYUNDAI MOTOR COMPANYInventors: Jooyoung Park, Byunghoon Yang
