摘要： PURPOSE: To shorten a shifting time and lessen a shifting shock by quickly changing a gear and smoothly changing torque as appearing on an output shaft, when a shifting process develops sufficiently after the fitting of a frictional engagement device at the engagement side. CONSTITUTION: When the prescribed gear change is implemented, the first frictional engagement device 1 is disengaged and the second frictional engagement device 2 is engaged. In this case, the engagement force of the device 2 is maintained at a low level with a low pressure holding instruction means 5 until the speed of the prescribed rotating member 4 reaches the preset level, and a gear change thereby progresses quickly. Also, when the speed of the member 4 reaches the preset level, the engagement force of the device 2 is increased with an engagement instruction means 6. In addition, when the speed of the member 4 reaches another preset level, the engagement force of the device 1 is increased with a pressure rise instruction means 7, resulting in a tie-up state. Furthermore, after the elapse of the preset time, an instruction signal is outputted for a release instruction means 8 to lower the engagement force of the device 1.

摘要： PROBLEM TO BE SOLVED: To provide a controller for a vehicle that keeps a travel permitted state as much as possible while protecting an electric oil pump, and the vehicle. SOLUTION: A controller 27 stops a motor generator MG2 while a shift lever is at its neutral position and varies the rotational frequency of the electric oil pump in an oil pressure controller 31 from a first rotational frequency to a second rotational frequency lower than the first rotational frequency when the electric oil pump enters a state that the operation at the first rotational frequency is not preferably carried on. Preferably, the controller 27 warns the driver to change the shift lever position from the neutral position to another position when the vehicle meets a predetermined warning condition. More preferably, the controller 27 places the vehicle in a travel disallowed state when the shift lever position is not changed from the neutral position to the other position after the warning.

摘要： PROBLEM TO BE SOLVED: To improve fuel consumption efficiency by increasing the use frequency of lean burn running when a vehicle travels, in a hybrid car having an engine and an electric motor as a power source when a vehicle travels and an engine control means for achieving lean burn running with an air fuel ratio larger than a theoretical air fuel ratio. SOLUTION: When the decision of a step SB3 is affirmed in requesting the acceleration of Δθ AC ≥β in lean burn driving, torque assist is performed by a motor generator 14 so that the current traveling status can be prevented from being deviated from a predetermined lean burn region in a step SB5. Thus, it is possible for the current traveling status to easily satisfy lean burn conditions, and to reduce such frequency that the vehicle travels by operating an engine 12 in the vicinity of a theoretical air fuel ratio on the contrary. Therefore, it is possible to further improve fuel consumption efficiency. COPYRIGHT: (C)2007,JPO&INPIT

摘要： PROBLEM TO BE SOLVED: To provide a control device of a four-wheel drive vehicle capable of proving a target drive force by driving front and rear wheels at an appropriate drive force distribution ratio corresponding to variations even if a vehicle state, a vehicle operating state, or a road state is changed. SOLUTION: This control device is set to a four-wheel drive mode driving the front and rear wheels when, in a second prime mover operation control means 154, the operating state of the vehicle in a vehicle start determination means 138, an acceleration operation determination means 146, a low temperature state determination means 162, and a wheel slip determination means 140 is in either of a start state, an accelerated state, and a low friction coefficient road surface traveling state. When the operating state is not in any of these states, the control device is set to a two-wheel drive mode for driving the front or rear wheels. By this, when they are in either of the start state, accelerated state, and low friction coefficient road surface traveling state, the control device is automatically set to the four-wheel drive mode driving the front and rear wheels. Accordingly, unnecessary four-wheel drive can be avoided according to the operating state to properly prevent a second prime mover operated to set to the four-wheel drive mode from being overheated.

摘要： PROBLEM TO BE SOLVED: To provide a control device for a hybrid vehicle by which torque-down control of input torque applied to a transmission is appropriately exerted under various operating conditions in the hybrid vehicle having the transmission between an engine, a motor generator and a driving wheel. SOLUTION: When the torque-down control is carried out at finishing changing of gears of power-on down-shift, the torque-down control (SB12, SB14) is performed causing torque of the motor generator to be lowered in engine + motor travelling mode and in motor travelling mode. On the other hand, the torque-down control is exerted (SB10) using the engine in principle in engine travelling mode, but when the torque-down control by the engine is unavailable, the torque down control is performed by applying reverse rotational torque to the motor generator (SB8).

摘要： PROBLEM TO BE SOLVED: To prevent the rotation speed of an engine from being transmitted fluctuated to a planet gear device, which is coupled directly with the engine without a torque converter in a hybrid vehicle wherein the power of the engine and a motor generator is compounded and distributed through the planet gear device and transmitted to a speed change gear. SOLUTION: In the hybrid vehicle which travels by compounding and distributing the power of the engine 10 and the motor generator 14 through the planet gear device 18 and transmitting the power to an automatic transmission, since the crank shaft 30 of the engine 10 is connected to the input shaft of the planet gear device 18 through a damper device 12, the fluctuation of the rotation of the engine 10 is prevented from being transmitted to the planet gear device 18 as it is.
