Abstract: PROBLEM TO BE SOLVED: To improve energy efficiency, in an internal combustion engine device having an exhaust supply device for supplying exhaust gas of an internal combustion engine to an intake system of the internal combustion engine. SOLUTION: If an engine operation stop is requested in the course of executing EGR (S110), idle operation time Tidl is set in a tendency of becoming long as the exhaust supply ratio E becomes large (S120). The engine is stopped (S180) after idly operating the engine over the idle operation time Tidle set at least after stopping the EGR (S130-S150). Thus, when an exhaust supply quantity is relatively small and when the suction air volume is relatively large, fuel consumption by useless idle operation before stopping the engine can be restrained, and the energy efficiency can be improved.

Abstract: PROBLEM TO BE SOLVED: To suppress the occurrence of an abnormal noise when a braking force of an electric motor is replaced with a braking force of an apparatus such as a hydraulic brake for imparting a braking force, and to maintain the driving quality in low-speed driving. SOLUTION: After a vehicle speed V becomes lower than a threshold value Vref, a motor torque Tm2 is replaced with a braking torque Tb of the hydraulic brake so that a rate value is changed in the middle and the regenerative torque of a motor is replaced with the braking force by the hydraulic brake. Thus, the abnormal noise to be generated in a state of outputting a large regenerative torque from the motor when the vehicle speed V is a little smaller than the threshold value Vref, is suppressed, and the braking force is smoothly replaced, thereby excellently maintaining riding quality in low vehicle speed.

SOLUTION: When the residual capacity (SOC) of a battery is a threshold Sref or more, a normal speed V1 is set as Lo-Hi shft line Vhi, and a shift in the shift level of a transmission is performed (S190, S210, S230), and when the residual capacity (SOC) of the battery is the threshold Sref or less, a vehicle speed V2 smaller than the vehicle speed V1 is set as a Lo-Hi shift line Vhi, and a shift in the shift level of the transmission is performed (S200, S210, S230). Thus, it is possible to improve the transmission efficiency of a transmission 60 when charging the battery, and to improve the fuel consumption of the vehicle. COPYRIGHT: (C)2007,JPO&INPIT

Abstract: PROBLEM TO BE SOLVED: To measure a travelling resistance of a hybrid vehicle more accurately. SOLUTION: In response to a coasting drive instruction for measurement of a travelling resistance of the hybrid vehicle, a change of a gear position in a transmission 60 is prohibited and both an engine 22 and a motor MG1 are stopped. A canceling torque is calculated, which cancels out a torque applied to a ring gear shaft 32a or a drive shaft via a power distribution integration mechanism 30 by generation of an inertia torque due to a change in the number of rotation of the motor MG1. The calculated canceling torque is set to a torque command Tm2* of a motor MG2, and the motor MG2 is driven and controlled with the torque command Tm2*. This arrangement makes the ring gear shaft 32a as a drive shaft completely free and enables accurate measurement of the travelling resistance of the hybrid vehicle during such a coasting drive of the hybrid vehicle in a fully non-driving state.

Abstract: PROBLEM TO BE SOLVED: To improve a mileage while ensuring driving force on an uphill road at the start of a vehicle.SOLUTION: Since a target gear ratio (target input rotation speed Nint) at the stop of the vehicle is set to a larger ratio as a road gradient becomes larger, speed change timing (L/U-off vehicle speed Vs0, Vs1) can be delayed when the road gradient is small such as on a flat road or a gradual uphill road. Thus, a range in which a gear ratio can be maintained at a Hi side can be widened and the mileage can be improved. In addition, when the road gradient is large, such as a steep uphill road, the driving force at the start of the vehicle can be ensured by setting the gear ratio at the stop of the vehicle to a maximum gear ratio γmax and therefore the mileage can be improved while ensuring the driving force on the uphill road at the start of the vehicle.

Abstract translation: 要解决的问题：在车辆启动时确保上坡道路上的驱动力的同时提高里程。 解决方案：由于随着道路坡度变大，车辆停止时的目标齿轮比（目标输入转速Nint）被设定为较大的比例，因此，变速时刻（L / U关车速度Vs0，Vs1 ）可以在道路坡度小的情况下延迟，例如在平坦的道路上或逐渐上坡的道路上。 因此，能够使在Hi侧保持齿轮比的范围变宽，能够提高里程。 此外，当道路坡度大的情况下，例如陡峭的上坡道路时，通过将车辆停止时的齿轮比设定为最大变速比γmax，可以确保车辆起动时的驱动力， 可以在确保车辆起点处的上坡道路上的驱动力的同时进行改进。 版权所有（C）2012，JPO＆INPIT

Abstract: PROBLEM TO BE SOLVED: To output driving force being suitable for driver's demand as much as possible. SOLUTION: This automobile determines whether there is driver's demand for increasing driving force or not based on opening Acc of an accelerator, obtains vehicle speed Vtmp when the demand for increasing driving force is given if the demand is given, and sets demand torque Tr* by utilizing a three-dimensional map of the opening Acc of the accelerator, vehicle speed V, and the demand torque Tr* decided by corresponding to the vehicle speed Vtmp. This map is set to a tendency to increase the demand torque Tr* when the vehicle speed Vtmp is low. This map is set to a tendency to prevent demand driving force from being greatly changed even if opening of the accelerator is more or less changed in a high speed region when the vehicle speed Vtmp is high and a tendency to make the demand torque Tr* substantially a fixed value in a high speed region of vehicle speed V. In this way, the vehicle can be driven by driving force corresponding to the vehicle speed Vtmp when the demand for increasing driving force related closely to driver's demand is given.

Abstract: PROBLEM TO BE SOLVED: To further increase the energy efficiency of an automobile with a motor connected to a drive shaft through a transmission while securing the traveling performance thereof on an uphill. SOLUTION: When the automobile is traveling in the Hi gear state of the transmission, if either of such requirements that a road surface gradient θ is equal to or higher than a prescribed gradient θref, a vehicle speed V is less than a prescribed vehicle speed Vref, a motor temperature Tm as the temperature of the motor is equal to or higher than a prescribed temperature Tmref, and an inverter temperature Tinv as the temperature of an inverter driving the motor is equal to or higher than a prescribed temperature Tiref (S140 to S170) is not satisfied, the transmission is maintained in the state of HI gear, and all of these requirements are satisfied, the transmission is changed from the state of Hi gear to the state of Lo gear (S180). Thus, since the transmission is normally maintained at a Hi gear while suppressing the lowering of the traveling performance and the defects due to the heating of the motor and the inverter when the automobile is started on the road surface of the uphill, the energy efficiency of the automobile can be further increased.
