Method for actuating a rear wheel steering

A travel path for a push rod of a rear wheel steering system, comprising:

• a constant speed section,
• a first deceleration section arranged at a first end of the constant speed section, and a second deceleration section arranged at a second end of the constant speed section, and
• a first overstroke section arranged adjacently to the first deceleration section such that the first deceleration section is disposed between the first overstroke section and the first end of the constant speed section, and
• a second overstroke section arranged adjacently to the second deceleration section such that the second deceleration section is disposed between the second overstroke section and the second end of the constant speed section.

A method for actuating a steering system of a vehicle, comprising:

• providing an actuator having:
• an electric motor with a rotor position sensor,
• a transmission configured to convert rotary motion of the electric motor to translational motion of a push rod so as to steer the vehicle, and
• a control unit, and
• initializing an actuator and forwarding a position of a push rod detected by a linear displacement sensor to the control unit,
• transmitting a target position of the push rod to the control unit and calculating a travel path of the push rod as a number of rotor revolutions of the rotor of the electric motor configured to be controlled via the rotor position sensor and the control unit,
• linearly displacing a push rod to an end position via the rotor position sensor, the push rod passing through an end of a central section of the travel path and a deceleration section of the travel path before achieving the end position.
