Title:

ON-VEHICLE ENGINE CONTROL DEVICE

Document Type and Number:

Japanese Patent JP2017185930

Kind Code:

A

Abstract:

PROBLEM TO BE SOLVED: To easily perform an evacuation operation at the occurrence of an abnormality, in an on-vehicle engine control device which includes an engine control function and a transmission control function.SOLUTION: A monitor control circuit part 130A and an error processing circuit part 160A monitor a control operation of a main control circuit part 120A. A first storage circuit 165a stores the control pedal when a frequency of the occurrence of a valve-open control abnormality reaches a prescribed threshold or higher, stops the drive of an intake valve opening controlling motor 108a of an intake throttle, sets the intake throttle at a fixed intake valve opening, stops power feed to an automatic transmission 109a when a gear change control abnormality occurs, sets a gear change ratio at a three-speed fixed gear change ratio, and at the occurrence of the abnormality, performs an evacuation operation by using a fixed intake valve opening and an automatic gear change, or a variable rotational speed and a fixed gear change ratio, or the fixed intake valve opening and the fixed gear change ratio. When there occur the valve-open control abnormality and the gear change control abnormality, fuel injection control is not unintentionally stopped.SELECTED DRAWING: Figure 1
