Abstract
【解決手段】駆動力配分制御部30では、差動制限トルク補正値演算部30hで、入力トルクTCDに基づき差動制限トルク補正値TLSDSを推定演算する。また、トランスファトルク演算部30iで、入力トルク感応トランスファトルクTLSD1に車体すべり角速度補正係数K(dβ/dt)を乗じてトランスファトルクTLSD2を演算する。そして、トランスファトルク補正・出力部30jで、トランスファトルクTLSD2から差動制限トルク補正値TLSDSを減算して、トランスファトルクTLSDを演算し出力する。
【選択図】図2
Description
図1〜図5は本発明の実施の一形態を示し、図1は車両全体の駆動系の概略構成を示す説明図、図2は駆動力配分制御部の機能ブロック図、図3は駆動力配分制御プログラムのフローチャート、図4は入力トルク感応トランスファトルクの特性図、図5は車体すべり角速度補正係数の特性図である。
(dβ/dt)=|((d2y/dt2)/V)−γ| …(1)
GTM=(NE・Rt)/((V/3.6)・Gfin) …(2)
ここで、Rtはタイヤ径、Gfinはファイナルギヤ比である。
TCD=TEG・GTM …(3)
TLSDS=α・TCD …(4)
ここで、αは、予め実験、計算等により求めておいた差動制限機構19のバイアス率である。尚、差動制限トルク補正値TLSDSは、(4)式のように演算して求めるのではなく、予め設定しておいたマップを参照して設定するようにしても良い。
TLSD2=K(dβ/dt)・TLSD1 …(5)
すなわち、トランスファトルク演算部30iは、締結トルク演算手段として設けられている。
TLSD=TLSD2−TLSDS …(6)
このように、トランスファトルク補正・出力部30jは、制御手段として設けられている。
