Title:
VEHICLE ENGINE CONTROL UNIT
Document Type and Number:
WIPO Patent Application WO/1990/006243
Kind Code:
A1
Abstract:
This invention relates to a vehicle engine control unit suitable for use in an automobile. When an abnormality detection signal of throttle valve control means (104) or throttle valve controlled variable setting means (103) is outputted and a range detection signal indicates a neutral range, output reduction controlled variable setting means (112) sets the controlled variable of engine output reduction means (111) so that the output drop of an engine (13) increases with an increase in the number of revolutions of the engine on the basis of an engine revolution detection signal and when the abnormality detection signal is outputted and the range detection signal indicates a driving range, it sets the controlled variable of the engine output reduction means (111) so that the output drop of the engine (13) decreases with an increase in the manipulated variable of the accelerator pedal on the basis of the manipulated variable detection signal described above. Accordingly, the engine (13) can be regulated within a predetermined range even when any abnormality occurs in the throttle valve control system.
