摘要： A secondary-battery internal short detection apparatus is provided which is capable of precisely detecting an internal short being generated in a secondary-battery. In this apparatus: an electricity-quantity storage circuit stores in advance a reference electricity-quantity necessary for charging the secondary-battery from a first voltage to a second voltage; an electricity-quantity accumulation circuit measures an accumulative electricity-quantity necessary for charging the secondary-battery from the first voltage to the second voltage; and an internal short detection circuit compares the accumulative electricity-quantity measured by the electricity-quantity accumulation circuit and the reference electricity-quantity stored in the electricity-quantity storage circuit, if the accumulative electricity-quantity is larger than the reference electricity-quantity, then decides that an internal short is generated, and if the accumulative electricity-quantity is equal to, or smaller than, the reference electricity-quantity, then without deciding that an internal short is generated, rewrites the reference electricity-quantity stored in the electricity-quantity storage circuit into the accumulative electricity-quantity.

摘要： A motor drive mode for driving a vehicle with only a second motor/generator is available in a selected one of two motor drive sub-modes consisting of a response-oriented motor drive sub-mode established by placing a forward drive clutch in a released state and placing a starting clutch in an engaged state, and a fuel-economy-oriented motor drive sub-mode established by placing the forward drive clutch in an engaged state and placing the starting clutch in a released state. In the response-oriented motor drive sub-mode in which an engine and a transmission are disconnected from each other, the engine can be efficiently started to change the vehicle drive mode to an engine drive mode, and an engaging action of only the forward drive clutch is required after starting of the engine, so that the engine drive mode can be established with a high response. In the fuel-economy-oriented motor drive sub-mode, the starting clutch is released to disconnect the transmission from the motor/generator, for reducing a power loss and improving fuel economy. After starting of the engine to establish the engine drive mode, an engaging action of only the starting clutch is required.
