<p><P>PROBLEM TO BE SOLVED: To favorably maintain an engine driving state by positively avoiding an engine stall caused by dropping of an engine speed, in an engine system equipped with an electronical control throttle device. <P>SOLUTION: In the throttle electronic control method carried out by the electronically controlled throttle device 1A carrying out opening and closing control of the throttle 3 via an actuator 7 by a command of an electronic control unit 10A, the electronic control unit 10A detects a neutral switch output signal, an engine speed sensor signal, and a vehicle speed sensor signal. If a shift position of a transmission is in a gear connected state, a vehicle speed is a predetermined determination traveling speed or more, and an engine seed is lower than a predetermined engine speed having a danger of causing an engine stall, throttle control is carried out to maintain an engine speed of a predetermined target engine speed or more to avoid an engine stall. <P>COPYRIGHT: (C)2008,JPO&INPIT</p> |
