    Abstract: PROBLEM TO BE SOLVED: To provide a vehicle, for varying the output characteristic of a driving force according to the amount of operation of an accelerator, to provide more appropriate output characteristic of the driving force without giving an uncomfortable feeling. SOLUTION: In the hybrid vehicle 20, an accelerator opening Acc* for execution is set using a map for setting normal execution opening, so that an accelerator opening Acc is gradually increased or decreased (step S120). When the accelerator opening Acc is equal to or larger than 100% of a practical maximum value and a kickdown switch 88 is turned on, the accelerator opening Acc* for execution is set using both a map for setting kickdown execution opening, which specifies the larger accelerator opening Acc* for execution relative to the same accelerator opening Acc than the map for setting normal execution opening, and the accelerator opening Acc by the driver (step S130).

    Abstract: PROBLEM TO BE SOLVED: To suppress the temporary omission of a damping force acting on a vehicle in the case of stopping the operation of an internal combustion engine under damping. SOLUTION: When a brake pedal is stepped on by a driver, and an engine stop request is made (time T1) while a damping torque is output from a motor MG2 and an oil pressure brake, a portion of the damping torque from a motor MG2 is replaced with the damping torque from the oil pressure brake, and the engine is smoothly stopped according to the control of the motor MG1. As a result, a power as the sum of the generated output of the motor MG1 and the generated output of the motor MG2 exceeds the input limit of a battery. Thus, it is possible to suppress the torque of the motor MG2 from being limited, and to prevent the torque omission of the damping torque. COPYRIGHT: (C)2007,JPO&INPIT

    Abstract: PROBLEM TO BE SOLVED: To transmit power from a motor MG2 more efficiently to a driving shaft in an automobile constituted to connect an engine, a motor MG1 and the driving shaft to a planetary gear mechanism and to connect a motor MG2 to the driving shaft through a transmission, and equipped with a mechanical pump driven by the engine to supply oil pressure to the transmission, and an electric pump driven by an electric motor to supply oil pressure to the transmission. SOLUTION: Even when demand power Pe* is a threshold Pref or less, when a torque command Tm2* of the motor MG2 is larger than allowable torque Tlim set in a tendency to be smaller as an oil temperature θoil is higher (S120, S200), the engine is continuously operated (S210). The transmission can thereby be operated using the oil pressure of oil force-fed from the mechanical pump and oil force-fed from the electric pump, and power from the Motor MG2 can be transmitted more efficiently from the motor MG2 to the driving shaft by the transmission compared with one stopping operation of the engine.

    Abstract: PROBLEM TO BE SOLVED: To restrain gear-shift shock at a gear change during the shutdown of the driving circuit of a motor, in a device which outputs power from a motor to a driving shift via a transmission or in a vehicle provided with such a device. SOLUTION: When a shift position SP is an N range, brakes are operated with a line hydraulic pressure PL, which operates brakes for shifting a gear of a transmission, at a low pressure Plo (S310), and when the shift position SP is not the N range, that is, a normal state, the brakes are operated with the line hydraulic pressure PL at a high pressure Phi (S320). By this, the engaging force acting on the brakes becomes larger more gradually than usual, and consequently the change per time of revolutions of a motor can be decreased when a gear is shifted, and the gear-shift shock which occurs with the change of the revolutions of the motor can also be restrained.

    解决方案:当换档位置SP为N档时,制动器以线路液压PL操作,该液压压力PL以低压Plo(S310)操作用于移动变速器齿轮的制动器,并且当换档位置 SP不是N范围,即正常状态,制动器以高压Phi的线路液压PL操作(S320)。 由此,作用在制动器上的接合力比通常变得越来越大,因此当齿轮移动时可以减少电动机的每转时间的变化,并且随着变化而发生的换档冲击 电动机的转速也可以被限制。 版权所有(C)2006,JPO&NCIPI

    Abstract: PROBLEM TO BE SOLVED: To further improve acceleration performance at stall starting while preventing the overcharge of a battery and charge by excessive large power. SOLUTION: In a hybrid automobile, an engine, a first motor, a drive shaft and a second motor are connected to a planetary gear mechanism, and the automobile comprises the battery that feeds powers to the two motors. Engine requirement power Pe* is set (S130, S180) by adding to an input limit Win of the battery the loss power Plstl and the margin power Pmgn of a drive system that are calculated on the basis of an upper limit value Tmmax of the torque of the second motor at the stall starting, the engine and the first motor are controlled, and the second motor is controlled in the range of the torque upper limit value Tmmax when a stall start is required when an accelerator pedal and a brake pedal are concurrently pedaled in at parking. By this, the acceleration performance when a brake is released after the stall start can be improved while preventing the overcharge of the battery and the charge by the excessive large power.
