Abstract: PROBLEM TO BE SOLVED: To avoid shifting shock during malfunction while quickly changing over a shift stage. SOLUTION: This automobile has a motor connected to a drive shaft via a transmission. Herein, in preparation for down-shift of the transmission with the engagement of a brake B2, a line hydraulic pressure PL is put into the condition of high pressure Phi by using a three-way solenoid 106 for adjusting a pressure control valve 108 to be opened/closed and then first fill for filling oil in a pack is executed by using a linear solenoid 111 for adjusting a control valve 113 to be opened/closed, and the line hydraulic pressure PL is changed over from the condition of the high pressure Phi to the condition of low pressure Plo after finishing the first fill for the engagement of the brake B2. Thus, the preparation of the engagement of the brake B2 is quickly executed and the shifting shock is avoided because the brake B2 does not suddenly engage even when the line hydraulic pressure BL is operated directly on the brake B2 with the malfunction of the linear solenoid 111 or others.

解决方案：该汽车具有通过变速器连接到驱动轴的电动机。 这里，为了准备通过制动器B2的接合来进行变速器的下降，通过使用用于调节压力控制阀108的三通螺线管106将管路液压PL置于高压力Phi的状态 打开/关闭，然后通过使用用于调节控制阀113打开/关闭的线性螺线管111来执行填充包装中的油的首先填充，并且将线路液压PL从高压Phi 在完成第一次填充以制动器B2的接合之后到低压Plo的状态。 因此，即使线性液压BL直接在制动器B2上操作，线性螺线管111的故障也能够快速地执行制动器B2的接合的准备，并且避免了制动器B2不会突然接合的换档冲击 或其他。 版权所有（C）2006，JPO＆NCIPI

Abstract: PROBLEM TO BE SOLVED: To provide a state detecting device for a transmission, preventing an error in detecting the state of the transmission.
SOLUTION: In a running gear for outputting power from a motor via the transmission to a driving shaft, a rotating speed Nr (a thick solid line in Fig.) of the driving shaft detected by a sensor (for example, a MRE sensor) which has detecting responsiveness changed with the rotating speed of the driving shaft has a response delay from a change in an actual rotating speed Nr (a thin solid line in Fig.) of the driving shaft when the rotating speed of the driving shaft is changed, while a rotating speed Nm2 (a thin dotted line in Fig.) of a motor detected by a sensor (for example, a resolver) which has relatively high accuracy and high responsiveness is almost equal to the actual rotating speed of the motor even when the rotating speed of the motor is changed. At this time, a moderating constant which is set to correspond to a response delay time constant is used for applying moderating control to the rotating speed Nm2 of the motor to calculate a regulated rotating speed Nm2smo (a thick dotted line in Fig.) so that a gear ratio calculated by dividing it by the rotating speed Nr is used for determining the malfunction of the transmission.

Abstract: PROBLEM TO BE SOLVED: To suppress exhaust emission from an internal combustion engine and suppress the occurrence of catalyst odor from a catalyst in an inert state by suppressing load on the internal combustion engine immediately after starting. SOLUTION: In a hybrid automobile having an engine and a motor connected to the engine, when the residual capacity of a battery becomes less and charging to a battery is requested when the automobile is stopped with a shift position at a P range, the charging to the battery is retained and the warmup operation of the engine is continued until a load operation prohibiting time tref set as a time shorter as a cooling water temperature Tw in engine starting is higher is passed (S140). After the load operation prohibiting time tref is passed, a power from the engine is regenerated by the motor and the charging to the battery is started (S150). By this, load on the engine during the warmup operation can be suppressed to suppress the exhaust emission and suppress the occurrence of catalyst odor from the catalyst in the inert state.

Abstract: PROBLEM TO BE SOLVED: To determine the suitability of the ignition timing of an internal combustion engine implemented in promoting the warming-up of a purifying device (catalyst) for purifying the exhaust gas of the internal combustion engine. SOLUTION: When the engine is started by a motor generator, the temperature of exhaust gas is raised by adjusting an ignition advance angle F to a lag side to warm up the purifying device (S102). After the adjustment of the ignition advance angle F, an engine torque Te outputted from the engine is calculated on the basis of reaction torque acting upon the motor generator (S108) and it is determined whether or not engine torque Te is smaller than criterion torque Tref preset corresponding to an engine speed and an intake air amount (S112), and the engine torque reaches the criterion torque Tref or higher, it is determined that ignition timing adjustment has some failure to turn on a warning lamp (S118). Engine output torque and ignition timing have fixed relations, therefore the suitability of the ignition timing adjustment can be determined by monitoring the output torque.

Abstract: PROBLEM TO BE SOLVED: To provide a motor operated valve control system for controlling driving electric power for a three-way change-over valve particularly at extremely low temperatures in a warm-up stroke of an internal combustion engine.
SOLUTION: The motor operated valve control system determines that the three-way change-over valve is frozen when the temperature of cooling water is not higher than a predetermined value (Y of S16), and the working condition of the three-way change-over valve after a predetermined time elapsed after voltage supply starting does not reach a predetermined state (Y of S20), it is determined that the three-way change-over valve is frozen. When it is determined the freezing, a driving voltage is stopped to be supplied to the three-way change-over valve (S22). This enables the three-way change-over valve to avoid the risk of damage. An operator is informed to check the concentration of an anti-freezing solution in cooling water (S24) so that an incentive to maintenance can be improved.

SOLUTION: The warm-up accelerating system displays graphics showing the proceedings of the warm-up stroke and the heat storage stroke on a display. With the expression of the proceedings in color variation, a driver easily recognizes the operated conditions of the warm-up accelerating system. Since the graphics are changed corresponding to the operated conditions of the warm-up accelerating system, the driver can wait for finishing the warm-up stroke with a good view thereof.

Abstract: PROBLEM TO BE SOLVED: To suppress gear shift shock by appropriately controlling an electric differential part at gear shifting of the transmission part in a vehicle driving device having the electric differential part and a transmission part. SOLUTION: During gear shifting of an automatic transmission 20, gear shift M1 torque TFF M1 is temporarily output so as to prevent an actual engine rotational speed N E from deviating from a target engine rotational speed N E * , due to the gear shifting.

Therefore, the actual engine rotational speed N E is properly prevented from deviating from the target engine rotational speed N E * at the time of gear shifting of the automatic transmission part 20.
