Abstract: PURPOSE:To improve a ride by detecting sprung behavior without using an acceleration sensor, detecting the production of flapping and pitching based on the sprung behavior and controlling suspension characteristics. CONSTITUTION:The fluctuation quantity DELTAVWL and DELTAVWR of sprung resonance frequency area are determined from the wheel speed VFL and VFR of right and left wheels, which are determined by the wheel speed sensors provided on the right and left wheels, and the resultant values are added to determine added value DELTAVw to which the same phase components of both fluctuation quantity are reflected. Whether this added value DELTAVw is larger than threshold Vref or not is judged to detect the switch condition of suspension characteristics. In addition, if the added value DELTAVw to which sprung behavior is reflected is larger than the threshold Vref, suspension characteristics are controlled hardly, and if it is the threshold Vref or less, suspension characteristics are controlled softly.

After this, the document data of such a page is retrieved from the document storage section 3, then it is converted to dot data and stored in a temporary storage section 9 for advance-converted data. Next, this dot data is read from the temporary storage section 9 for advance-converted data per page, and the document data of a page which is not stored in the temporary storage section 9 for advance-converted data is read from the document storage section 3. Finally, the readout document data is converted in a data buffer for printout conversion 5 and then is output to a printout device 6.
