Patent Searching and Data

Document Type and Number:
Japanese Patent JP3499906
Kind Code:

PURPOSE: To carry out estimated value calculation at a new variable speed in a short time by correcting a physical quantity, acceleration or the estimated value, so that an estimated value corresponding to the magnitude of driving resistance calculated based on relationship between the physical quantity and the acceleration may become same before and after speed change, at the time of speed change.
CONSTITUTION: A physical quantity in relation to engine combustion calculated by a physical quantity detection means (b) and vehicle acceleration detected by an acceleration detection means (c) are inputted to a driving resistance calculation means (d). An estimation value corresponding to the magnitude of driving resistance is calculated by the driving resistance calculation means (d) based on the physical quantity and the acceleration. In this case, the physical quantity, the acceleration and the estimated value are corrected by a corrective means (h) so that the estimated value becomes same before and after the speed change. A speed change pattern is varied by a pattern varying means (e) in response to a determined estimated value. The speed change ratio is determined in the speed change pattern by a speed change ratio determination means (f), so that operation means (g) may be controlled.
