ENGINE CONTROL DEVICE
First Claim
1. An engine control device applied to a vehicle equipped with:
- an electric actuator for changing a suspension property of said vehicle;
a suspension control device for driving said actuator; and
an internal combustion engine,the engine control device comprising an engine control part programmed to;
automatically stop the operation of said engine when a predetermined engine operation stop condition is satisfied; and
automatically start the operation of said engine when a predetermined engine operation start condition is satisfied,wherein said engine control part is programmed to;
judge if a malfunction occurs in said suspension control device;
continue the operation of said engine when a stop inhibition requesting signal for inhibiting the automatic stop of the operation of said engine is sent to the engine control device in order to drive said actuator and said engine control part judges that no malfunction occurs in said suspension control device even if said engine operation stop condition is satisfied; and
ignore said stop inhibition requesting signal and automatically stop the operation of said engine when said engine operation stop condition is satisfied and said engine control part judges that the malfunction occurs in said suspension control device even if said stop inhibition requesting signal is sent to the engine control device.

Abstract
An engine control device applied to a vehicle equipped with an actuator for changing a suspension property of the vehicle, a suspension control device for driving the actuator, and an engine. The engine control device automatically stops the engine operation when a stop condition is satisfied and automatically starts the engine operation when a start condition is satisfied. The engine control device continues the engine operation when a signal for inhibiting the automatic stop of the engine operation is sent to the engine control device in order to drive the actuator and the engine control device judges that no malfunction occurs in the suspension control device even if the stop condition is satisfied. The engine control device ignores the signal and automatically stops the engine operation when the stop condition is satisfied and judges that the malfunction occurs in the suspension control device even if the signal is sent to the engine control device.
