Abstract: <P>PROBLEM TO BE SOLVED: To minimize effect of sensor resolution, zero point correction, noise, or the like, and to accurately estimate road surface friction coefficient without vibrational steering input.  <P>SOLUTION: A correlation coefficient calculating section 15 receives wheel acceleration of the front right and left wheels where operation component has been eliminated from high-pass filters 13 and 14, and calculates a correlation coefficient. An upper/lower limit calculating section 16 of the correlation coefficient of a population sets upper and lower limits of the correlation coefficient of the population, a first correction gain setting section 18 sets a first correction gain varying in response to a driving state, and a second correction gain setting section 19 sets a second correction gain varying in response to a travel state. A correlation coefficient calculating section 17 of the population calculates a correlation coefficient of the present population based on the correlation coefficient from the correlation coefficient calculating section 15, a correlation coefficient of a previous population, the upper and lower limits, and the first and second correction gains. A road surface μ estimating section 20 compares the correlation coefficient of the present population with a determination threshold previously set according to the driving state and estimates a road surface μ.  <P>COPYRIGHT: (C)2005,JPO&NCIPI

IPC: H02M1/08
Filed: 2003-05-28
Abstract: <P>PROBLEM TO BE SOLVED: To provide a modulation system and method for a switching amplifier that can reduce filtering requirements and crossover distortion.  <P>SOLUTION: A modulation system 10 can drive an associated load 20 that is coupled between a pair of outputs by providing a switching signal at one of the outputs and a non-switching signal at the other output independent of the direction of current relative to the respective outputs.
