Abstract: PROBLEM TO BE SOLVED: To more properly suit to the environment environment, and to suppress the charging and discharging of the electrical storage device due to unexpected power. SOLUTION: A correction coefficient keg is set based on intake air temperature Ta or atmosphere pressure Pa on which the density of the intake air of an engine is reflected (S140), a target power Pe* to be output from the engine is set by multiplying the set correction keg by a power P* required by a vehicle (S150), and the engine and motors M1 and M2 are controlled so that the target power Pe* can be output from the engine, and that required torque Tr* based on an acceleration opening Acc can be output (S160 to S210). Thus, it is possible to suppress the charging/discharging of the battery due to an excessive power based on the output of an excessive power from the engine or the output of an insufficient power depending on air density.

Abstract: PROBLEM TO BE SOLVED: To suppress overheating of an electric motor, and its driving circuit in an automobile wherein the electric motor is connected to a drive shaft via a transmission. SOLUTION: When a vehicle speed V is less than a predetermined vehicle speed Vref, and a motor current Im applied to the motor is a predetermined current Iref or more, basically, output torque To outputted to the drive shaft is estimated on the basis of motor torque Tm based upon the motor current Im, engagement torque Tc* is set such that the estimated torque To matches with required torque T* required in the drive shaft, a corresponding brake of the transmission is controlled by the set engagement torque Tc* (S190-S210), and the motor is controlled such that a revolution Nm of the motor matches with a predetermined rotation Nset (S220, and S230). By this, since the motor can be rotated while outputting power to the drive shaft, the current concentrates in only one particular phase of a three phase coil of the motor, and overheating of the electric motor and its driving circuit can be suppressed.

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 provide a controller for vehicle which can suppress the torque fluctuations, in a range where the revolution of a motor is low, in a vehicle which can be driven by a motor. SOLUTION: An ECU30 is equipped with a torque computer 52, a time constant determining section 53, and a primary delay filter 54. The torque computer 52 computes a basic torque command TRb, based on the power Pm that a motor generator MG can output and the number of revolutions MRN of a motor. The time constant determining section 53 determines the time constant, based on the motor revolution MRN. The primary delay filter 54 outputs a torque command TR, by eliminating the frequency components generated in the basic torque command TRb by the fluctuations of the motor revolution MRN. The time constant T determining section 53 determines the time constant T so that the time constant T, when the motor revolution MRN is lower than a specified value, is larger than the time constant T when the motor revolution MRN is higher than a specified value.

Abstract: PROBLEM TO BE SOLVED: To perform adequate driving control for avoiding obstacles while a vehicle travels.
SOLUTION: When a risk that an obstacle approaches is determined to exist, a map-switching determination part 22 outputs a determination signal to use a low accelerator-responsiveness correlation map. A map storage part 24 stores not only a correlation map in ordinary traveling which is used when an obstacle does not approach but also a correlation map which is lower in accelerator responsiveness than in the case of the ordinary traveling. When the risk that an obstacle approaches is determined to exist, a driving quantity computing part 26 selects a correlation map which is lower in accelerator responsiveness than in the case of the ordinary traveling in accordance with a determination signal. Then, the driving quantity computing part 26 outputs a driving-force signal which corresponds to a driving quantity obtained from the correlation map to a driving-force generating part.
