    摘要: A hybrid electric drive system for a vehicle comprises a combustion engine (1), a transmission (2), a first clutch (3) disposed between the engine (1) and the transmission (2), a rotating electric machine (4) which serves as a motor as well as a generator, a second clutch (30) disposed between the rotating electric machine (4) and the transmission (2), and a storage device (9). When the second clutch (30) is commanded to connect the rotating electric machine (4) to the transmission (2), a control unit (10) controls the rotating electric machine (4) so as to decrease the difference between the rotation speeds of the rotating electric machine (4) and the transmission (2) (S2) and cause the second clutch (30) to connect the rotating electric machine (4) to the transmission (2) only after the difference decreases to a allowable value (S3, S4).

    摘要: A controller (10) of a hybrid vehicle determines an engine torque at a point on an engine torque high efficiency line at the current engine rotation speed as a target engine torque, and determines the current engine torque from the current engine rotation speed and current accelerator depression amount. Then, when the gear position of a transmission (2) is neutral, the vehicle is stationary and a storage device (9) requires charging, the controller (10) sets the difference between the target engine torque and the current engine torque as a target power generation torque of a motor generator (4), sets a transitional time period corresponding to the target power generation torque, and performs control over the transitional time period to raise the power generation torque of the motor generator gradually to the target power generation torque.

    摘要: A temperature-sensitive type urea sensor 74 is adopted for use in an engine exhaust gas purifying apparatus. The magnitude of convection of urea aqueous solution generated in a storage tank 41 is determined based on temperature information detected by the urea sensor 74. For detection of abnormality, a detected concentration Dn is adopted when the percentage GRDt of temperature change of urea aqueous solution is small, so that convection is small and it is determined not to affect accurate detection of an abnormality.

    摘要: The present invention is directed to defrost a reducing agent with cooling water of an engine and to prevent water scale from being deposited and accumulated on a cooling water pipe for circulating the cooling water. A frozen reducing agent is defrosted by being heated with cooling water of an engine. A cooling water pipe for guiding the cooling water to a reducing agent tank is provided with a cutoff valve. To defrost the reducing agent, the cutoff valve is opened. Even in the case where the reducing agent is not frozen, the cutoff valve is opened for a predetermined period after start of the cutoff valve to circulate the cooling water in the cooling water pipe.
