Engine control unit

摘要

The invention enables economical operation while securing drivability to low vehicle velocities.
In the invention, a suspension-of-ignition directing unit 115 suspends the ignition when the throttle is completely closed and shuts down the engine. The vehicle velocity determination unit 112 determines in which predetermined vehicle velocity ranges the vehicle velocity when the throttle is completely closed resides. The timer 114 is set for various time periods depending on the results of detection as the time limits for suspending the ignition. The suspension-of-ignition directing unit 115 shuts down the engine when the time of the timer 114 is up and the time limit for suspending the ignition has elapsed. The time limit for suspending the ignition is set so as to decrease with increase in vehicle velocity.
