Abstract
Method for determining steering deadband and eliminating starting drag in a vehicle, having at least one steered wheel mechanically connected to an actuator, includes, from a first initial position, wherein the actuator is in a middle position and is biased toward a second direction, the actuator is moved toward a first direction, the first direction being opposite to the second direction, until a movement of the steered wheel is detected in a first deadband detection position of the actuator. The actual position of the actuator in the first deadband detection position is stored as a first deadband value ΘDB1. After reaching the first deadband detection position, the actuator is moved further in the first direction by a predetermined ΘESD1 first starting drag elimination angle to cause a predetermined movement of the at least one steering wheel and further mechanical parts connected thereto arriving to a first starting drag elimination position.
