摘要： A SAT estimating portion supplies a grip degree estimating portion with the estimated SAT value. A summing device sums a front wheel slip angle on which high pass filter processing has been performed and a front wheel slip angle on which low pass filter processing has been performed so as to obtain an integrated slip angle. A grip degree estimating portion estimates a grip degree of a tire, by calculating a SAT reference value which is based on the integrated slip angle, and calculating a ratio between the SAT reference value and the estimated SAT value. A road surface μ value estimating portion estimates a road surface μ value when the grip degree becomes equal to or lower than a reference value.

摘要： A motor-driven steering controller for controlling a steering wheel of a vehicle. The controller includes a steering torque controlling unit, a braking force estimating unit, a right and left braking force difference estimating unit and an assist steering torque providing unit. The steering torque controlling unit controls a steering torque on the steering wheel depending on a steering operation. The braking force estimating unit estimates braking forces to be imposed on wheels of the vehicle. The right and left braking force difference estimating unit estimates difference between the braking forces to be imposed on the right and left wheels each estimated by the braking forces estimating unit. The assist steering torque providing unit provides an assist steering torque for the steering torque controlling unit on the basis of the difference in braking force between right and left wheels estimated by the right and left braking force difference estimating unit.

摘要： A characteristics change of a control object is functionally represented by a parameter &thgr; which varies between values of 0 and 1 as the gain of the control object is surveyed. The frequency of the identification signal is set at a frequency where the difference in gains becomes large. The amplitude of the identification signal is set so that the variation width of the output of the control object is less than or equal to a predetermined value. Because the identification accuracy improves where the input/output characteristics with respect to the parameter are more sensitive, the identification signal set by such a setting apparatus imparts high identification accuracy. Moreover, because the amplitude of the identification signal is set based on the variation width of the output of the control object, identification can be performed without significantly affecting the output of the control object.
摘要翻译：在控制对象的增益被调查的情况下，控制对象的特征变化在功能上由参数θ表示，该参数θ在0和1的值之间变化。识别信号的频率被设定为增益差变大的频率。识别信号的幅度被设定为使得控制对象的输出的变化幅度小于或等于预定值。由于相对于参数的输入/输出特性更敏感，因此识别精度提高，所以由这种设定装置设定的识别信号具有高识别精度。此外，由于基于控制对象的输出的变化宽度来设定识别信号的幅度，因此可以在不显着影响控制对象的输出的情况下进行识别。
