A drive control apparatus for a hybrid vehicle which has an engine selectively set in one of a normal fuel-consumption operation mode and a low fuel-consumption operation mode for obtaining a lower fuel consumption; a generator selectively used for one of being driven by the engine and assisting driving of the engine; a motor for generating a driving force of the vehicle by electric power supplied by the generator or a battery device; and a clutch between the generator and wheels of the vehicle. The drive control apparatus has a control part for performing a low fuel-consumption driving assistance mode when the engine is set in the low fuel-consumption operation mode. In the low fuel-consumption driving assistance mode, the clutch is connected, and driving of the vehicle is assisted using one of the generator and the motor, which is selected in accordance with an operation state of the vehicle.

Drive control apparatus for hybrid vehicle

A hybrid vehicle is provided in which, since the driving force of a generator/motor (M) disposed so as to surround the outer periphery of an input shaft () of a transmission (T) is transmitted to an output shaft () of the transmission (T) via an endless chain (), it is possible to carry out the so-called leg shaft drive, in which transmission of the driving force between the generator/motor (M) and the output shaft () is carried out without going through an engine (E) and the input shaft (), thus reducing power consumption and enhancing energy recovery efficiency during regenerative braking. Furthermore, since a crankshaft () of the engine (E) and the input shaft () of the transmission (T) are disposed coaxially, and the generator/motor (M) is disposed at a position sandwiched between the engine (E) and the transmission (T), it is possible to employ the same layout for the generator/motor (M) as for a conventional sandwiched generator/motor, and the leg shaft drive system can be employed without greatly modifying the design of the transmission (T).

A power control apparatus for a hybrid vehicle (), the hybrid vehicle including an internal combustion engine (), a front motor-generator (), and a transmission () which are connected to front wheels (Wf), and a rear motor-generator () which is connected to rear wheels (Wr) via a rear differential gear box (DR). A calculated value, which is obtained by subtracting a front output power F_POWER and an accessory output power DV_POWER from a battery output power limit B_LimPow is set as an rear output power limit R_LimPow. The smaller of a rear drive command R_PowCmd (which is set depending on the running state of the vehicle) and a rear output power limit R_LimPow is set as a new rear drive command R_PowCmd. Accordingly, a demanded motor output power can be obtained without increasing the size of the main battery ().

Power control apparatus for hybrid vehicle

In a hybrid vehicle in which front wheels are driven by an engine and a front motor, and rear wheels are driven by a main rear motor and a sub rear motor, both main rear motor and the sub rear motor are driven when a large driving force is required as when the vehicle is driven at low speed to haul a trailer or the like or to run on a sandy ground, whereas when the required driving force is small, only the main rear motor is driven.

An engine is connected to front wheels via a primary motor, a clutch and a transmission, and a secondary motor is connected to rear wheels. A vehicle is driven by the secondary motor while performing a combustion suspended idle operating condition in which the engine which has been brought to a combustion suspended condition is run idly by the primary motor according to driving conditions of the vehicle. The necessity for idling the engine is obviated so as to reduce the fuel consumption. Further, the engine can also be started up in quick and secured fashions by resuming the control of fuel supply and injection to the engine which is being run idly with its combustion being suspended and driving the primary motor while reducing the consumed power to a minimum level by reducing the load of the primary motor which runs the engine idly with its combustion being suspended.

In a hybrid vehiclein which a transmissionis connected via a first clutchto an internal combustion engineand a first motorthat are coupled in series to front wheels Wf, a second motorwhich is a three-phase brushless DC motor is connected to the transmissionvia a second clutch. When the vehicle in an idling stop state of the internal combustion engineis to be started, a motor output control portioncalculates a torque which is required of the second motorin accordance with the inclination angle of the road surface on which the vehicle is traveling, and also a continuous energization time period Tof a stator winding of one phase in the second motor
