Abstract: A vehicle steering apparatus includes a variable gear ratio mechanism which is provided in a steering force transmitting system, and a lock mechanism which restricts relative rotation of an input shaft and an output shaft of the transmitting ratio changing mechanism. The lock mechanism is engaged by inserting a lock arm in a indented portion of a lock holder of the lock mechanism. A play angle when the lock mechanism is engaged by inserting the lock arm in the indented portion is set to be smaller than a rotational angle of a motor which is required for outputting six different signals.

Abstract: A torque detector that suppresses fluctuation of an output value relative to fluctuation of an input value and that also has the output value accurately follow the input value even when the input value changes suddenly. The torque detector includes a detection element, a converter, and a hysteresis processor. The detection element detects the steering torque applied to a steering shaft when the steering shaft is rotated to generate an analog torque signal corresponding to the steering torque. The converter converts the analog torque signal to a digital torque signal. The hysteresis processor performs hysteresis processing on the digital torque signal to include the value of the digital torque signal in a predetermined range.

Abstract: A steering system comprises a steering wheel and a feedback mechanism in communication with the steering wheel. A control unit communicates with a sensor and controls the feedback mechanism based on the signal from the sensor. The feedback mechanism may cause tactile feedback in the steering wheel. The feedback mechanism is most preferably incorporated by controlling a solenoid valve in a power steering circuit for the vehicle. By repeatedly actuating the solenoid valve, vibration can be caused in the steering wheel.

Abstract: A method for lane-keeping control of a lane-keeping support system provides a current command indicative of steering torque assist needed to steer a vehicle in following a target line between lane markings on a roadway during driving in lane-keeping control (LKC) mode. A map has two sets of limit data against a range of values of lateral acceleration to which the vehicle is subject, between which sets of limit data there is a range of values of the command during various phases of steering the vehicle to turn in the LKC mode. In order to compensate for undesired effect caused by any deviation of the range of values of the current command due to the presence of continuous disturbance, the two sets of limit data are corrected. To determine driver steering intervention, the instantaneous value of the current command is compared to two limit values established out of the corrected two sets of limit data.

Abstract: A method is disclosed for determining a steering wheel angle calibration reference value in a vehicle. The vehicle includes a relative steering wheel angle sensor, which is unique in that it receives power directly from the vehicle's battery and interacts with the vehicle's car area network. The vehicle also includes an active yaw controller that interacts with the vehicle's car area network. The steering wheel angle calibration reference value only needs to be updated when power to the relative steering wheel angle sensor has been interrupted.

Abstract: The present invention involves a system and method of controlling a steering wheel for simulated steering feel on a steering wheel of a vehicle with front road wheels in a steer-by-wire system. The method includes sensing actual torsion on the steering wheel, comparing the actual torsion to a threshold torque value, sensing actual angular velocity of the steering wheel, and comparing the actual angular velocity to a threshold angular velocity. The method further includes generating a simulated steering feel torque on the steering wheel, if the actual torsion is greater than the threshold torque value and the actual angular velocity is less than the threshold angular velocity. The method further comprises returning the steering wheel to the center position at a specified angular velocity, if the actual torsion is less than the threshold torque value and the actual angular velocity is greater than the threshold angular velocity.

Abstract: In the conventional electric power steering control system, a gain by which an approximate differentiation value of a torque signal is multiplied comes to be large at high speed driving. Therefore, a problem exits in that unstable feel of steering increases, thereby steering convergence getting worse. An electric power steering control system includes a variable type torque differential operation device 104A that makes variable a differential time constant at the time of outputting a second motor current, and a time constant determining device 105X that commands the time constant to the variable type torque differential operation device 104A. The time constant determining device 105X determines the time constant in response to any change in not less than one signal selected and used in an arbitrary manner out of a speed signal 81, a torque signal 82, a yaw rate signal 83 and a steering rate signal 84.
