Abstract: PROBLEM TO BE SOLVED: To provide a warm-up accelerating system allowing easy recognition of proceedings of a warm-up stroke and a heat storage stroke.
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: PURPOSE: To prevent such a possible that a catalyzer might come to an undue temperature rise due to the effect of supercharging in time of a misfire occurrence, in such a constitution that there is no fuel-cut immediately after the misfire has happened. CONSTITUTION: Fuel is fed to a combustion chamber 4 of an engine 1 by an injector 11. Air to be fed to the combustion chamber from an intake passage 6 is supercharged by a supercharger 21. Exhaust gas to be exhausted to an exhaust passage 7 from the combustion chamber 4 is purified by a three-way catalyst. In this engine 1, when the generation rate of a misfire in the combustion chamber 4 grows larger to some extent, a supply of fuel by the injector 11 is cut off. Supercharging by the supercharger 21 is controlled according to a driving state of the engine 1. Here, the misfire happening in the combustion chamber 4 is detected by a crank angle sensor 46 or the like. An electronic control unit(ECU) 50 opens an air bypass valve(ABV) 32 at the time of judging the generation of the misfire on the basis of the detected result of the sensor 46 and restricts the operation of the supercharger 21, whereby the supercharging is reduced at once.

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. The time to start outputting the gear shift M1 torque TFF M1 in the direction for suppressing a rotational speed difference ΔN E is corrected by learning control based on the rotational speed difference ΔN E during the gear shifting of the automatic transmission part 20. 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.

Abstract: PROBLEM TO BE SOLVED: To more properly set timing of a loaded operation of an internal-combustion engine. SOLUTION: A hybrid vehicle sets a threshold Pref1 based on a vehicle speed V and sets a threshold Pref 2 larger than the threshold Pref 1 by engine start-up power Ps (S120), and when vehicle required power P* exceeds the threshold Pref 1 in traveling while stopping an engine, starts the engine and controls the engine and a motor MG1, MG2 so as to travel the car while outputting required torque Tr* set involving a loaded operation of the engine (S130-S150, S210-S270).

Abstract: PROBLEM TO BE SOLVED: To improve a feeling of operation in down-shift regardless of the input restriction of an electricity accumulating device. SOLUTION: When a shift position SP is changed from a D position to an S position, or down-shift is performed at the S position (S160), braking side torque is made to act on a driving shaft by the motoring of an engine by a first motor and a second motor, and request torque Tr* is output within the range of input/output restriction Win and Wout of a battery (S220 to S280), and torque which can not be output from the second motor since it exceeds the input restriction Win of the battery among the request torque Tr* is output to the driving shaft by a hydraulic brake for traveling (S290). Thus, it is possible to output torque Td (T) for down-shift giving a feeling of operation similar to shift feeling in a type of motor vehicle equipped with a stepped automatic shift to a driver (S170 to S210), and to improve the feeling of operation in down-shift regardless of input restriction Win.

Abstract: PROBLEM TO BE SOLVED: To perform control considering drive requirement of a driver, in a vehicle having a motor that can output power to an axle shaft. SOLUTION: When a torque exceeding a predetermined value is outputted from a motor for a predetermined time while a vehicle is in a stop state while outputting a corresponding torque based on the opening of an accelerator Acc, the torque from the motor 22 is reduced with a torque reduction ratio Rd2 to move the vehicle backward (Steps S300-S410). When the phase where the motor current is concentrated is switched (Step S330), a torque command Tm2* is set so as to increase the torque from the motor MG2 with the torque increase ratio Ri set based on the opening of the accelerator Acc in the stop state and an estimated gradient value θ (Steps S450-S470, S390-S410).

Abstract: PROBLEM TO BE SOLVED: To improve fuel economy and responsiveness of driving force to be outputted to a drive shaft, and to suppress the occurrence of vibration or abnormal noise. SOLUTION: When request torque Tr* to be output to a drive shaft (ring gear shaft), when an accelerator is turned off exceeds a value 0, request torque Tr* is reduced by using a rate value Trt2 which is smaller than a rate value Trt1 (S160). A value calculated by subtracting a correction revolution speed ΔN, based on input/output restrictions Win, Wout of a battery 50 from the revolution speed, corresponding to a shift position SP or a speed V is set as a target revolution speed Ne* of an engine 22 (S170, S180). As a result, it is possible to suppress the discharge power of a battery from exceeding the output restriction Wout, and to suppress the occurrence of abnormal noise, such as, the rattling sounds of a gear, or vibration due to the rapid change of the torque of the drive shaft.

Abstract: PROBLEM TO BE SOLVED: To appropriately change a gear ratio of a transmission. SOLUTION: In the driving device changing the speed by the transmission and transmitting the power from a motor to a driving shaft, when an absolute value of a deviation between reference torque Tm2r0 as driving shaft side torque Tm2r at the time of starting of change of a shift stage of the transmission and driving shaft side torque Tm2r during changing of the shift stage is lower than a threshold α until change of the shift stage is completed (S280), learning of an engagement state of a brake of the transmission and a state of the oil pressure supplied to the brake during changing of the shift stage is done (S290). When changing the shift stage, an actuator of the transmission is drive-controlled using the learned result. Thereby, the deviation of the transmission by secular change is corrected, and the shift stage of the transmission is suitably changed. COPYRIGHT: (C)2006,JPO&NCIPI

Abstract: PROBLEM TO BE SOLVED: To provide a device for outputting power from a motor via a transmission to a driving shaft, making it possible to change the shift stage of the transmission when impossible to change it with the synchronization of the rotating speed of the motor. SOLUTION: When the shift stage of the transmisision is changed to increase the rotating speed Nm2 of the motor (S300), constant pressure stand-by is performed by using stand-by pressures Pb1, Pb2 of brakes B1, B2 which are set to be greater as the output limit of a battery is smaller (S350) and the rotating speed Nm2 of the motor is increased to a rotating speed Nm2* after changed by the semi-engagement of positive torque of the motor with the brakes B1, B2. Thus, even when the output limit of the battery is smaller to make it impossible to change the shift stage with the synchronization of the rotating speed of the motor before/after changing the shift stage, the semi-engagement with the brakes B1, B2 is used to change the shift stage.
