Patent ID: 7883443

Claim:
An engine control system for a vehicle comprising: a throttle operation detector configured to detect whether or not a throttle valve for controlling an amount of air taken into an engine of the vehicle has been operated to be opened; a clutch condition detector configured to detect whether a clutch is in an on-state to permit transmission of a drive force from the engine to a running drive element or in an off-state not to permit transmission of the drive force; and a controller configured to execute control to increase the amount of air taken into the engine to an amount larger than an idling air amount corresponding to an idling engine speed when the vehicle is traveling, when the throttle operation detector detects that the throttle valve has not been operated to be opened, and when the clutch condition detector detects that the clutch is in the off-state; wherein the controller is configured to execute dashpot control to increase an opening degree of the throttle valve to an idling position corresponding to the idling engine speed, thereby increasing the amount of air taken into the engine; wherein the throttle valve is a first throttle valve, and wherein the controller is configured to execute control to open the first throttle valve to a predetermined angle in association with an operation of a second throttle valve that is arranged in series with the first throttle valve in an air flow direction and is configured to be driven by an actuator.
