A shift position of an electric powered vehicle is selected by operating a shift lever and a P position switch. A power source position is selected by operating a power switch. When any of switching elements forming an inverter device is short-circuited, selection of the shift position and the power source position is controlled such that simultaneous selection of a power source position at which inverter control is turned off and a shift position at which a parking lock mechanism is inactivated can be avoided. Therefore, inverter control for reducing short-circuit current caused by back electromotive force derived from rotation of a motor generator after occurrence of short-circuit failure can reliably be executed.

A method for verifying a drive torque applied by an electric machine in a hybrid drive of a motor vehicle, the motor vehicle being propelled by the electric machine and / or an internal combustion engine, and it being checked if the drive torque applied by the electric machine is determined accurately. In order to ensure that the operating strategy is correctly implemented and a shift in load level in the power train functions reliably during operation of the motor vehicle, the drive torque applied by the electric machine is evaluated with regard to its accuracy, using a drag torque generated by the combustion engine during an overrun fuel cut off.

Problems with accuracy reading position detection signal peaks and minute phase differences in the detection current make motor drive control easily susceptible to differences in motor characteristics. The rotor position is determined based on whether or not a neutral point difference voltage, which is the difference voltage between the neutral point voltage and the pseudo-neutral-point voltage when the motor phases are selectively energized, exceeds a specific threshold value. The phase energized to start the motor is determined based on this determination and the motor is energized accordingly to start. Instead of switching directly from the search step at the initial rotor position to the back-EMF voltage mode, a search and start mode that creates initial rotor speed sufficient to start the motor is executed before entering the back-EMF voltage mode.

A vehicle has a low voltage power generating unit mounted thereon, which passively generates low voltage power when the vehicle is electrically connected to commercial power supply through coupling of a connector unit. A winding transformer transforms the commercial power supply input to the primary side with a prescribed ratio of transformation, and the transformation is performed without requiring any control signal from the outside. The AC power with voltage lowered, output from the secondary side of winding transformer, is rectified by a diode unit, and a low voltage power is generated. The low voltage power generated by the diode unit is supplied through a supplementary low voltage DC line to a sub battery and to a controller.

After columnar electrodes and a sealing film are formed above a semiconductor substrate in a wafer state, probe pins are brought into contact with the upper surfaces of the columnar electrodes, and burn-in is executed. Next, solder balls are formed on the columnar electrodes, and the semiconductor substrate in a wafer state is diced. As a result, any unwanted deformation of the solder balls by contact of the probe pins can be prevented. In addition, even when the heights of the solder balls vary, burn-in can be performed.
