Abstract:
A controller (10) for a hybrid vehicle (HV) idles first an internal combustion engine (ICE; 12) when it is predicted that a load on the HV or a motor (14) will increase, and thereafter switches to a travelling mode in which the ICE (12) is used. Based on output of a vehicle weight sensor (62), a gradient sensor (64), a towing sensor (68), a start/power mode switch (60) and other on-board sensors or switches, it is predicted that a load on the HV or the motor (14) will increase. Otherwise, based on information obtained from a navigation system (66) or from another vehicle to be towed, it is predicted that a load on the HV or the motor (14) will increase. Based on a difference of output between an open air temperature sensor (70) and a cabin temperature sensor (72), a load on an on-board appliance (e.g., 50) is detected, and based on the detected load, it is predicted that a load on the HV or the motor (14) will increase. Thus, a delay in following the ICE (12) in response to the switching of travelling modes can be decreased or remedied.

Abstract:
A hybrid drive system (8, 120, 130, 210) for a motor vehicle, having an engine (10, 212) operated by combustion of a fuel, an electric energy storage device (114, 258) for storing an electric energy, a motor/generator (12, 214) connected to the electric energy storage device, and a synthesizing/distributing mechanism (14, 216) which includes a first rotary element (144, 216r), a second rotary element (14s, 216s) connected to the motor/generator, and a third rotary element (14c, 216c), and an output member (18, 226) connected to the third rotary element, wherein a first clutch (16, CE1) is provided for connecting the first rotary element (14r, 216r) and the engine, and a second clutch (20, CE2) is provided for connecting two elements of the first, second and third rotary elements of the synthesizing/distributing mechanism, for rotation of the two elements as a unit.
Abstract:
An oil pressure generator 20 includes a drive gear 30, a driven gear 32, and a crescent 34, which constitute a gear pump unit, as well as one-way clutches 36 and 38 that respectively interlock with two rotating shafts 42 and 46 when the rotating shafts 42 and 46 rotate in an identical direction relative to the drive gear 30. In case that both the rotating shafts 42 and 46 rotate in the interlocking direction, the corresponding one-way clutch interlocks with the rotating shaft having a greater revolving speed, thereby driving the drive gear 30. This structure enables the oil pressure generator 20 to produce an oil pressure through rotation of the rotating shaft having a greater revolving speed out of the two rotating shafts 42 and 46.

A hybrid drive employing an engine (150) and two electric motors (MG1,MG2), has an oil pressure generator or pump (20) which includes a drive gear (30), a driven gear (32), and a crescent (34), which constitute a gear pump unit, as well as one-way clutches (36) and (38) that respectively interlock with two rotating shafts (42,156) and (46,126) when the rotating shafts (42,156) and (46,126) rotate in an identical direction relative to the drive gear (30). In case that both the rotating shafts (42,156) and (46,126) rotate in the interlocking direction, the corresponding one-way clutch interlocks with the rotating shaft having a greater revolving speed, thereby driving the drive gear (30). This structure enables the oil pressure generator (20) to produce an oil pressure through rotation of the rotating shaft having a greater revolving speed out of the two rotating shafts (42,156) and (46,126).
