Document Type and Number:
Japanese Patent JP2935563
Kind Code:
B2
Abstract:
PCT No. PCT/EP90/00503 Sec. 371 Date Oct. 21, 1991 Sec. 102(e) Date Oct. 21, 1991 PCT Filed Mar. 30, 1990 PCT Pub. No. WO90/12702 PCT Pub. Date Nov. 1, 1990.The invention relates to a method for filtering out disturbances in the form of short term wheel acceleration signals when the wheel exhibits an overall deceleration, so that a more accurate deceleration signal can be used for control of drive slippage. Wheel speed v is measured at intervals TA and speed changes for each interval are determined. When a change is negative or zero following a positive change in a previous interval, the wheel speed is stored as a maximum speed vmax while v continues to be measured and a counter determines the period of time DELTA t between the occurrence of vmax and the instantaneous value v. Beginning at a predetermined filtering time DELTA T after storing vmax, a quotient DELTA v/ DELTA t representing the filtered slope of the value v is determined and used as a control variable to regulate wheel slippage.
