Abstract

A new shift-by-wire system having a stand-by mechanical link with a backlash has been proposed. The link directly connects the select lever and the manual lever of the automatic transmission in case of emergency. Thus it is necessary to keep the backlash free during normal operations without generating a force. The angles of the manual lever driven by an actuator should follow the angles of the select lever exactly and quickly. A two-degrees-of-freedom model matching control is developed to meet this requirement. It is shown that the backlash is kept to be free during range select operation.
