Idling engine speed control system for a vehicle and vehicle equipped with idling engine speed control system
First Claim
1. An idling engine speed control system for a vehicle comprising:
- a valve which is provided within an air-intake passage connected to an engine mounted in the vehicle and is configured to substantially open and close the air-intake passage;
a drive device configured to open and close the valve;
an opening degree controller configured to drive the drive device, the opening degree controller being configured to control an opening degree of the air-intake passage;
an input device which is attached to the vehicle and is configured to input a target engine speed in an idling state; and
an engine speed memory configured to store the target engine speed input with the input device;
wherein the opening degree controller is configured to control the opening degree of the air-intake passage in the idling state according to the target engine speed stored in the engine speed memory.
