ENGINE START CONTROL DEVICE FOR HYBRID ELECTRIC VEHICLE

Title:

ENGINE START CONTROL DEVICE FOR HYBRID ELECTRIC VEHICLE

Document Type and Number:

WIPO Patent Application WO/2012/056857

Kind Code:

A1

Abstract:

A hybrid electric vehicle comprises an engine and a motor as a driving source. The engine and the motor are coupled to each other via a first clutch capable of varying a torque transmission capacity. When the engine is started, the first clutch is engaged and the engine is cranked by a driving force of the motor. In addition, the hybrid electric vehicle has a first start mode in which an engine being stopped is started through an acceleration operation and a second start mode in which the engine being stopped is started through other than the acceleration operation. The torque transmission capacity of the first clutch during cranking of the engine is set such that the capacity at the second start mode is relatively lower than that at the first start mode.
