Abstract
A power transmission control device, which is applied to a hybrid-vehicle provided with an internal combustion engine (E/G) and a motor (M/G) as power sources, includes a manual transmission and a friction clutch. When the shift position is in “neutral”, the friction clutch is in an engaged state, an accelerator opening is “0”, and a battery remaining amount SOC is less than a threshold TH, a charge condition is satisfied. When the charge condition is satisfied, charge of a battery by using an E/G torque is carried out. Specifically, the M/G is driven, by using the E/G torque, as an electrical power generator, and electric energy acquired by electric power generation by the M/G is used to charge the battery. As a result, for the HV-MT vehicle, by using the internal-combustion-engine torque, the battery for supplying the electric motor with the electric energy can be efficiently charged.
