Title:
HYBRID SYSTEM, HYBRID VEHICLE, AND POWER TRANSMISSION METHOD FOR HYBRID SYSTEM
Document Type and Number:
WIPO Patent Application WO/2015/020061
Kind Code:
A1
Abstract:
A direct coupling is established with a crankshaft (15) of an internal combustion engine (10) to transmit power between the crankshaft (15) and an electric power generator (21) via a continuously variable transmission (16); a rotational speed ratio (Rn) (=Na/Ne), which is the ratio of the rotational speed (Na) of the electric power generator (21) relative to the rotational speed (Ne) of the internal combustion engine (10) of the continuously variable transmission (16), is reduced when the internal combustion engine (10) is stopped, increasing the load exerted on the crankshaft (15); and the crank angle (θ) when the crankshaft (15) has stopped is brought within a preset stop range (θ1-θ2). The startup time of the internal combustion engine (10) is thereby shortened when the internal combustion engine (10) is started up or restarted after an idling stop, and a hybrid vehicle (1, 1A) equipped with a hybrid system (2, 2A) can be quickly transitioned to a traveling state.
