The variable torque distribution control system has an electronic control device (8) detecting dynamic driving characteristics, allowing under-control or over-control of the vehicle to be detected, for controlling a clutch (1a) in a longitudinal drive tran...

A power distribution control system for a vehicle, in which a front/rear drive-force distribution control unit computes a torque-response-torque, a revolution-difference-response-torque and a yaw-rate feed back torque. When a torque down command by a tract...

A target yaw rate setting unit of a control characteristics changing unit computes a first target yaw rate based on the radius of curvature of a curve. A target yaw rate setting unit of a braking force control unit computes a second target yaw rate based o...

A forward and aft torque distribution system and a method of controlling forward and aft torque distribution for a four-wheel vehicle having an electronically controlled clutch to control split of drive torque to be transferred to front and rear wheels are...

A vehicle is equipped with a coupling such as, for example, a center differential (3) or a variable clutch (90), that transmits a driving force from an engine (1) to a front-wheel drive shaft (4F) and a rear-wheel drive shaft (4R) while allowing a differen...

There is provided a driving force control system for a four-wheel drive vehicle. An automatic-mode transmitted torque (MDTR,MDTL) is calculated based on operating conditions of the vehicle (S403,S406). When lock mode-executing conditions including operatio...

In a control system for variable torque distribution for a four-wheel-drive vehicle with a brake control system (8) through which wheel-selective brake intervention is possible, a non-variable longitudinal lock with a predetermined torque distribution rati...
