PROBLEM TO BE SOLVED: To recognize exact accelerator position by preventing errors in learning of the accelerator full closed position. SOLUTION: Processing for updating minimum value data APMIN of an accelerator position sensor is repeated at a prescribed cycle during the operation. When the prescribed time passes after the completion of the operation, whether the actual accelerator position is in the closing side from a fixed limiter LM1 is inspected (S70). If the accelerator position is in the opening side from the fixed limiter LM1, learning of the full closing position is stopped, while if the accelerator position is in the closing side from the fixed limiter LM1, whether the actual accelerator position is in the closing side from the accelerator position by a variable limiter LM2 obtained by adding a set valueαto the minimum value data APMIN is inspected (S80). When the actual accelerator position is in the opening side from the accelerator position by the variable limiter LM2, learning of the accelerator full closing position is stopped, while when the actual accelerator position is in the closing side from the variable limiter LM2, full closing positioned data of the accelerator position sensor is updated (S90).
