Audi vehicles won't rock n' roll
By RIZAL JOHAN | 02 September 2020INGOLSTADT: How do you provide a large SUV with sporty road-holding properties and minimal body roll without impairing ride comfort?
Audi has resolved this conflict of objectives by means of electromechanical roll stabilisation (eAWS). Assisted by the 48-volt onboard electrical system and powerful actuators, the stabilizers on the front and rear axle can be actively controlled according to the driving situation.
As a result, the models retain their high level of ride comfort in straight-line driving. By contrast, in cornering and load alteration situations, they impress with enhanced lateral dynamics combined with minimal body roll.
The technical advantages of Audi’s electromechanical solution: it is energy-efficient, operates in near-real-time and is maintenance-free due to the absence of hydraulic elements.
Unlike hydraulic solutions, the eco-friendly electromechanical system does not require oil circuits and is maintenance-free.
It is even able to recuperate energy by capturing suspension impulses on its electric motor, converts them into electrical energy and stores it in the lithium-ion battery of the onboard electrical system.
The electromechanical solution uses energy more efficiently as well. In contrast to hydraulic circuits, it does not have to store and provide pressure.
