Vehicle control system

A vehicle control system comprising:

• an actuator reciprocating a shift-changing valve which changes the shift range of the automatic transmission to a shift range corresponding to a movement position;
• a restriction member adapted to restrict the movement of the shift-changing valve when the shift-changing valve moves to a terminal end of the reciprocative movement range;
• a range detector for detecting the present shift range of the automatic transmission;
• a controller which, when a shift range changing command instructing a change to an instructed shift range selected by a vehicle occupant is inputted, controls the actuator while making reference to detection signals detected by the range detector and moves the shift-changing valve to the position corresponding to the instructed shift range;
• and
• a memory which stores, for each shift range interval, the amount of operation of the actuator performed when moving the shift-changing valve from a position corresponding to a certain shift range to a position corresponding to another shift range,
• wherein the controller determines the state of the range detector on the basis of the detection signals detected by the range detector,
• when the range detector is determined to be in an abnormal condition, the controller moves the shift-changing valve until the movement is restricted by the restriction member to define the position of the terminal end, and controls the actuator with respect to the defined terminal end position and on the basis of the amount of operation in order to move the shift-changing valve to the position corresponding to the instructed shift range.
