发明名称 Corrective control system and method for liquid pressure control apparatus in automatic transmission
摘要 In corrective control system and method for a liquid pressure control apparatus for a control valve unit, fundamental maps are preset on the basis of a hysterisis characteristic, the hysterisis characteristic being exhibited in such a manner that an output liquid pressure actually measured value which takes along a first hysterisis loop when the current value is increased toward a larger value is different from that which takes along a second hysterisis loop when the current value is, in turn, decreased toward a smaller value from the larger value and each fundamental map is a map representing a relationship between the output liquid pressure actually measured value and a current average value, the current average value being an average between the current value in the first hysterisis loop and that in the second hysterisis loop with respect to each of the same output pressure actually measured values.
