摘要： Disclosed are a method and system of controlling anti-jerk for reducing vibration of an electric vehicle using power of a motor. The method includes outputting an actual speed of the motor; outputting a model speed of the motor; obtaining a vibration component based on a deviation between the output motor speed and actual speed of the motor; high pass filtering the vibration component to remove an error component in the vibration component; delaying a phase of the filtered vibration component for a preset time to compensate for phase error occurring during the high pass filtering; and applying a preset gain to the vibration component in which the phase is delayed for the preset time to generate an anti-jerk compensation torque based on the applying of the preset gain.

摘要： An anti-jerk control system and method of an eco-friendly vehicle are provided to prevent a driver from sensing a difference in vehicle starting at an initial stage when the vehicle is parked on a downhill road. The anti-jerk control method uses a motor as a driving source and includes calculating an actual speed of the motor, calculating a model speed of the motor, and acquiring a gradient of a road, on which the vehicle is located, using a gradient detector. Additionally, the method includes determining a speed offset value that corresponds to the acquired gradient, compensating the model speed by the speed offset value, and calculating a motor vibration component using a difference between the compensated model speed and the actual speed of the motor. Then, anti-jerk compensation torque is calculated using the calculated motor vibration component.

摘要： Disclosed is a technique of correcting a resolver offset by measuring and correcting an offset of a resolver assembled to a motor of an eco-friendly vehicle in an accurate and simple way. The offset measurement process includes, after completing the assembly of a resolver a resolver to a motor, rotating the motor by using a rotation device able to transfer a rotation force to the motor, setting a voltage instruction and current-controlling the motor according to the voltage instruction, and obtaining a d-axis current and a q-axis current, which are feedback currents, during the current-control of the motor. Then when the system is in a steady state, a resolver offset ({tilde over (θ)}) is calculated from the d-axis current and the q-axis current by using {tilde over (θ)}=tan−1(d-axis current/q-axis current).
