<p><P>PROBLEM TO BE SOLVED: To prevent the generation of shock caused by the racing of an engine and the lowering of an engine rotating speed caused by the change of engine load, when the neutral control is started and terminated. <P>SOLUTION: The engine output is reduced by controlling an ISC valve to be closed at a predetermined start timing tiscs, when the neutral control is started (time t<SB>2</SB>), and the engine output is increased by controlling the ISC valve to be opened at a predetermined termination timing tisce, when the neutral control is terminated (time t<SB>5</SB>). Whereby the racing of the engine and the lowering of the engine rotating speed NE caused by the change of engine load can be inhibited in starting and terminating the neutral control, even though the response from the change of an opening of the ISC valve to the change of the engine output caused by the actual increase and decrease of the intake air amount, is poor. <P>COPYRIGHT: (C)2004,JPO</p> |
