Today's automotive applications of brake based traction control (B-TCS) and dynamic stability control (DSC) continue to penetrate the market as an approach to enhance vehicle traction and stability. However, there is also a growing trend in the use of electronically controlled couplings and differentials.The Electronic Torque Manager (ETM®), developed and manufactured by GKN Driveline, provides an innovative solution to driveline torque distribution as well as enhanced vehicle stability combined with adaptive control strategies.The ETM®'s unique actuation system actively controls the torque transfer between axles or across an axle differential. The system consists of a ball ramp mechanism, in conjunction with a multi-plate clutch, directly actuated by an electric motor. An Electronic Control Unit (ECU) incorporating adaptive control strategies provides the required control.This paper provides an overview of the ETM® working principle, functional characteristics, application scope, as well as key performance features.
