Abstract
An engine ECU executes a program including: the step of outputting a fuel-cut instruction when conditions that an accelerator position PA is not higher than a threshold value and a rate of increase DNE of engine speed NE is not lower than a determination value DNE(0) are satisfied; the step of fully closing throttle opening; and the step of suspending ignition of air-fuel mixture by a spark plug.
Claims28
A controller for an internal combustion engine coupled to a transmission through a friction engagement element transmitting a driving force, comprising
- a control unit controlling said internal combustion engine such that number of rotations of an output shaft of said internal combustion engine is reduced when an accelerator position is smaller than a predetermined open position and rate of increase in the number of rotations of the output shaft of said internal combustion engine is larger than a predetermined determination value.
A controller for an internal combustion engine, comprising:
- a determining unit determining whether number of rotations of an output shaft of the internal combustion engine is to be reduced or not;
- and
- a control unit controlling said internal combustion engine such that, when it is determined that the number of rotations of the output shaft of said internal combustion engine is to be reduced, the number of rotations of an output shaft of said internal combustion engine is reduced by retarding ignition timing in said internal combustion engine and thereafter suspending fuel injection in said internal combustion engine.
A controller for an internal combustion engine coupled to a transmission through a friction engagement element transmitting a driving force, comprising
- control means for controlling said internal combustion engine such that number of rotations of an output shaft of said internal combustion engine is reduced when an accelerator position is smaller than a predetermined open position and rate of increase in the number of rotations of the output shaft of said internal combustion engine is larger than a predetermined determination value.
A controller for an internal combustion engine, comprising:
- determining means for determining whether number of rotations of an output shaft of the internal combustion engine is to be reduced or not;
- and
- control means for controlling said internal combustion engine such that, when it is determined that the number of rotations of the output shaft of said internal combustion engine is to be reduced, the number of rotations of an output shaft of said internal combustion engine is reduced by retarding ignition timing in said internal combustion engine and thereafter suspending fuel injection in said internal combustion engine.
A controller for an internal combustion engine coupled to a transmission through a friction engagement element transmitting a driving force, comprising
- an ECU, wherein
- said ECU controls said internal combustion engine such that number of rotations of an output shaft of said internal combustion engine is reduced when an accelerator position is smaller than a predetermined open position and rate of increase in the number of rotations of the output shaft of said internal combustion engine is larger than a predetermined determination value.
A controller for an internal combustion engine, comprising
- an ECU, wherein
- said ECU determines whether number of rotations of an output shaft of the internal combustion engine is to be reduced or not, and
- controls said internal combustion engine such that, when it is determined that the number of rotations of the output shaft of said internal combustion engine is to be reduced, the number of rotations of an output shaft of said internal combustion engine is reduced by retarding ignition timing in said internal combustion engine and thereafter suspending fuel injection in said internal combustion engine.
