Abstract:
1. A method for generating a request command of a wheel alignment apparatus using a motor-drive power steering (MDPS) comprising: setting, by a request value generation unit, an initial value of a request command basic design function, when an activation command is inputted according to an input of an activation switch; receiving an initial steering angle through a steering angle sensor after setting the initial value; setting a control period comprising an angular velocity acceleration period, a constant angular velocity period, and an angular velocity deceleration period from the initial steering angle, in order to align the wheel with the center, wherein the control period is set by the request value generation unit based on the initial steering angle; and generating a request profile according to the control period; wherein the request value generation unit is configured such that the angular velocity acceleration period and the angular velocity deceleration period are set to be the same.
