Title:
HYBRID-VEHICLE CONTROL DEVICE
Document Type and Number:
WIPO Patent Application WO/2012/011495
Kind Code:
A1
Abstract:
Provided is a hybrid-vehicle control device that can continue high-speed driving, without transitioning to the HEV mode, by raising the motor torque limit during driving in the EV mode. The hybrid-vehicle control device includes: an engine (Eng); a motor (MG) that starts the engine (Eng) and that drives driving wheels (RL, RR); a first clutch (CL1) that switches between the HEV mode and the EV mode; an automatic transmission (AT); and an electric-vehicle mode control means (Fig. 4). The smaller the transmission ratio of the transmission (AT) is during driving in the EV mode, the smaller the value of the engine start torque (TmESOD), which is reserved for transitioning to the HEV mode, is made by the electric-vehicle mode control means (Fig. 4).
