Control system for engine with auxiliary device and related engine control method
First Claim
1. A control system for an engine with an auxiliary device, driven with an output torque of the engine, for driving a vehicle, the control system comprising:
- auxiliary device control means for controlling a drive torque of the auxiliary device;
engine control means for executing an engine torque control to vary the output torque of the engine; and
failure detecting means for detecting a failure, related to an operating parameter of the engine, which adversely affect engine torque control being executed with the engine control means;
wherein the auxiliary device control means alters a drive control of the auxiliary device in response to the failure detected with the failure detecting means.

Abstract
An engine control method and related engine control method are disclosed for an engine with an auxiliary device of a vehicle wherein auxiliary device control means controls a drive torque of the auxiliary device, engine control means executes an engine torque control to vary the output torque of the engine, and failure detecting means detects a failure giving an adversely affect to engine torque control executed with the engine control means. The auxiliary device control means alters a drive control mode of the auxiliary device in response to the failure detected with the failure detecting means. In preferred embodiment, the auxiliary device is driven in a collaborative control mode in the presence of an extremely mild failure, a fixed voltage control mode in the presence of a mild failure and a gradual change control mode in the presence of a fatal failure.
