Title: Idling speed control device for engine
Inventor: FUJIMOTO MISAO
IPC: F02D9/02
Filed: 1988-02-08
Abstract: PURPOSE:To prevent a large scale of undershoot of engine speed by retarding switching of a target engine speed at the time of switching an automatic speed change gear from a stopping range to a running range. CONSTITUTION:When it is detected that a shift lever of an automatic speed change gear is being switched from a stopping range to a running range at the time of idle-running of an engine, a target engine speed is set to be lower in the running range compared with that in the stopping range. Further, when the engine speed is switched from the stopping range to the running range, switching of the target engine speed is retarded. Undershoot of the engine speed at the time of switching of operating range can therefore be prevented.
