  • Patent number: 6771708
    Abstract: A nonlinear compensator comprising a signal processing section, a distortion detecting section, and a distortion correcting section. The signal processing section detects the time difference and phase difference between two signals by calculating correlation, synchronizes the two signals with each other, and causes the phase of one signal to coincide with that of the other. The distortion detecting section determines an amplitude error and a phase error in the two signals and inputs the errors as distortion components to a distortion correcting section. The distortion correcting section sequentially selects the amplitude, the phase, and the amount of compensation corresponding to the value of the amplitude from the amounts of compensation registered at the initial stage and updated adaptively, and adds the amount of compensation to the digital base band signal obtained at the input demodulation section to compensate for the distortion components.

  • Patent number: 6269290
    Abstract: In an engine-motor hybrid vehicle, vehicle drive regions are divided into a plurality of groups specified by a plurality of operation state variables. A learning variable set for each drive region is updated according to an amount of a power state of an engine, when the vehicle is in a steady state running. The learning variable indicates a change in the power state amount with age. When an engine power demand value is determined, it is corrected by using the learning variable of a selected drive region to calculate a corrected engine power demand value compensating a change in the engine with age. In this manner, the engine power is controlled.

  • Patent number: 5828973
    Abstract: An electric power steering apparatus for recovering a steering wheel to its neutral position based on the speeds of the steered wheels of a vehicle. In response to a steering torque signal from a torque sensor, assisting torque by a motor is controlled in a torque servo system from a phase compensating filter to a current detecting unit. A microcomputer calculates a speed ratio of left and right wheels based on wheel speeds detected by wheel speed sensors. Recovery compensating torque is obtained from the speed ratio of the left and right wheels, and a corresponding signal is output to an addition calculating unit. The addition calculating unit adds the steering torque signal and the signal representing the recovery compensating torque to obtain a recovery compensated signal. Based on the recovery compensated signal, the assisting torque is controlled to recover the steering to its neutral position.

  • Patent number: 5650708
    Abstract: An inverter control apparatus for driving a polyphase AC motor for preventing abrupt changes in motor drive currents when switching of one phase is stopped. The apparatus includes a signal generator for generating duty signals of drive signals of respective phases on the basis of a generated reference waveform and a signal modifier for selecting one of the duty signals of one phase, holding it at a predetermined level, and modifying the duty signals of other phases according to the value required to hold the selected duty signal. On the basis of three-phase signal voltage levels, a decision is made on voltage fixing phase intervals by a phase decision circuit, and shift values are determined by an adder at every voltage fixing phase interval. Shift values are selected by a multiplexer according to the outputs of the phase decision circuit and added to triangular wave voltage. Resultant sum values are compared with the three-phase signal voltages to form a three-phase PWM signal.
