Patent number: 6771708Abstract: 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.Type: GrantFiled: September 18, 2000Date of Patent: August 3, 2004Assignee: Kabushiki Kaisha ToshibaInventors: Masaru Suga, Seiji Isobe, Takeshi Sawada

Patent number: 6269290Abstract: 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.Type: GrantFiled: June 30, 1999Date of Patent: July 31, 2001Assignee: Denso CorporationInventors: Tsuneyuki Egami, Kazuyoshi Obayashi, Hiroya Tsuji, Yasumasa Kaji, Keiichiro Banzai, Takeshi Sawada

Patent number: 5828973Abstract: 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.Type: GrantFiled: March 15, 1996Date of Patent: October 27, 1998Assignee: Nippondenso Co., Ltd.Inventors: Kanji Takeuchi, Takeshi Sawada
