    Abstract: PROBLEM TO BE SOLVED: To control the heat generation of a motor and incompatibility to a driver. SOLUTION: In a vehicle, a torque reduction rate value RT1 is set with a tendency of becoming smaller as road surface gradient α and vehicle weight M get larger (S340), when an absolute value of vehicle speed V is a threshold Vref or less, a previous torque command (previous Tm*) of a motor is a threshold Tmref or more, and a temperature rise promotion time t is a threshold Tmref or more. A torque command Tm* is set by subtracting the torque reduction rate value RT1 from the previous torque command (previous Tm*) of the motor (S400). The motor is driven and controlled with the torque command Tm* set up. Thereby, the temperature rise of the motor and an inverter driving the motor can be controlled by backing up a vehicle at more appropriate speed. COPYRIGHT: (C)2009,JPO&INPIT

    Abstract: PROBLEM TO BE SOLVED: To allow an inverter to be cooled with proper cooling performance according to a heating amount of inverter switching elements in a system provided with a cooling device for cooling the inverter.SOLUTION: A higher one of switching frequencies for first and second inverters 22 and 23 is set as a switching frequency for inverter cooling control. Further, a higher one of motor outputs for first and second AC motors 12 and 13 is set as a motor output for inverter cooling control. A target cooling water flow rate for inverter cooling control according to the switching frequency and motor output for inverter cooling control is calculated, and an electric water pump 39 is driven so that a flow rate of cooling water for a cooling device 40 may be the target cooling water flow rate. This makes it possible to properly respond to variation in the heating amount of inverter switching elements due to any change in the switching frequency and motor output, which changes a flow rate of the cooling water, so that the cooling performance of the cooling device 40 can vary.

    Abstract: PROBLEM TO BE SOLVED: To eliminate the need of preliminary adaption when suppressing a rattling sound in starting an internal combustion engine from a stop state. SOLUTION: When the start request of an engine is made when a shift position is set to a parking position, pressurization torque Tp is set to a torque command Tm2* of a motor MG2 before the start of the engine (step S160), and a motor is controlled so that the torque Tp can be output from the motor MG2. Then, time change quantity dθe2/dt of an electrical angle θe2 of the motor MG2 is changed to any significant value other than a value 0 (step S140), and time change quantity dθe1/dt of an electrical angle θe1 of the motor MG1 is changed to any significant value other than the value 0 (step S150). Thus, it is possible to assume that the filling looseness of a gear mechanism between the motor MG1 and the motor MG2 is completed, and the rattling sound is put to a suppressable state. Afterwards, the start of the engine is permitted. COPYRIGHT: (C)2009,JPO&INPIT
