Abstract: A drive unit for a vehicle may include a motor, a casing accommodating the motor, an electric pump unit attached to a lower part of the casing and configured to circulate heat medium within the casing and a filter unit attached to the lower part of the casing and configured to filter the heat medium. At least a part of the electric pump unit and at least a part of the filter unit each protrude outside the casing. Outside the casing, the filter unit is adjacent to the electric pump unit from a front in the vehicle.

Abstract: Provided is a telecommunication apparatus and a telecommunication method accomplishing a one-to-many, many-to-one, and many-to-many simultaneous accesses in a power line telecommunication of a code division multiple access (CDMA) by using an AC power line (including the ground).

Abstract: An electric power steering apparatus including a steering angle detection part that detects a steering angle of a steering wheel and outputs a steering angle signal, a steering control unit that controls a motor to give an assist torque to the steering wheel, an abnormality detection part that determines an abnormality of the steering angle detection part, and a motor angle detection part that detects a rotational angle of the motor. The steering control unit calculates a steering angle information based on at least the steering angle signal, and includes a signal storage part that stores the steering angle information. The steering control unit runs the motor continuously when the abnormality detection part detects the abnormality of the steering angle detection part until a vehicle stops or until the abnormality detection part determines that the steering angle signal returns to a normal state from the occurrence of the abnormality.

Abstract: An electric power steering apparatus is provided with a means for correcting a motor assist so as to inhibit a quick steering, when a foreseeable roll amount based on a difference between a first SAT (self-aligning torque) value which does not include a rolling motion of a vehicle and a second SAT value which includes the rolling motion of the vehicle is larger than a predetermined value.

Abstract: The present invention provides an excellent electric power steering apparatus in which torque ripple caused by a quantization error of a current control system generated in case of slow steering state and steering holding state, namely, vibration and noise on a steering wheel can be suppressed. A current controller in which a steady state gain of feedback control is a finite value is used so as to be capable of suppressing the vibration and noise. Further, according to the present invention, a smoothing filter is included in a current control system so that the quantization error is smoothed so that the torque ripple is suppressed.

Abstract: A signal superposing apparatus designed, in accordance with a basic power line model taking account of the term of the mutual inductance and that of a self inductance of a transformer connected to AC power lines, with the circuit constants of capacitors selected appropriately to minimize the distortion of information waveform by the effect of the impedance of the transformer, will permit any desired waveform to be superposed over power signals with its distortion being kept to the minimum. In this way, for example a stepwise pulse waveform can be superposed over power signals with the distortion of waveform being minimized, and accordingly CDMA is made possible in a power line carrier system whereby information signals are communicated with power signals on AC power lines being used as carrier wave.
