Abstract

A controller of a driver for a vehicle comprising an uphill driving force control means for increasing the driving force of a vehicle such that an acceleration of vehicle substantially equivalent to that at the time of traveling on a flat road can be attained even if the output request amount during uphill traveling is substantially equal to that during flat road traveling, in which a strange feeling being imparted to an operator during uphill traveling is suppressed. Since start of uphill driving force control by the uphill driving force control means (130) is delayed by a delay control means (131) until a decision is made by a first predetermined period judging means (134) that period (T) exceeds the first predetermined period (T1) in which acceleration difference (G') between the reference vehicle acceleration (G) and the actual acceleration is no less than the predetermined uphill judging threshold (alpha), wherein, a vehicle driving force (F) does not increase even during uphill traveling controlled by the uphill driving force until the first predetermined period (T1), thus a strange feeling being imparted by the decreasing of a predetermined acceleration (G) to an operator during uphill traveling is suppressed.

Description

technical field

[0001] The present invention relates to a control device for a drive system of a vehicle, and more particularly, the present invention relates to a control device so arranged that it is compatible with a vehicle during driving on a flat road under a vehicle output demand substantially the same as a given vehicle output demand. For driving force comparison, the control device is used to increase the vehicle driving force during uphill running of the vehicle at the given vehicle output requirement, so as to obtain substantially the same vehicle acceleration during uphill running as during flat road running. Background technique

[0002] There is known a vehicle configured to adjust the driving force during uphill travel of the vehicle at the same accelerator pedal operation amount, ie, the same vehicle output demand amount, as during flat road travel of the vehicle. Patent Document 1 describes an example of the vehicle. This document discloses such a technolog...
