IDLE STOP CONTROLLER FOR HYBRID VEHICLE

Title:

IDLE STOP CONTROLLER FOR HYBRID VEHICLE

Document Type and Number:

Japanese Patent JP2003176738

Kind Code:

A

Abstract:

To improve stability of auxiliary machine drive in an idle stop of a hybrid vehicle.

This controller has a motor generator MG3 connected to an engine ENG through a one-way clutch CL allowing power transmission only from the engine ENG side, and the auxiliary machines P/S, CMP, ATP connected to the motor generator MG3. Until a rotational speed N3 of the motor generator MG3 reaches a target rotational speed N* and becomes stable after the idle stop of the engine ENG, the motor generators MG1, MG3 drive the auxiliary machines P/S, CMP, ATP. After the rotational speed N3 of the motor generator MG3 reaches the target rotational speed N* and becomes stable, the motor generators MG1, MG3 drive the auxiliary machines P/S, CMP, ATP while gradually reducing drive force of the motor generator MG1 to zero.
