New electromechanical rotary dampers being tested at Audi

LinkedIn +

Audi is working on the development of a technology called eROT, in which electromechanical rotary dampers replace the hydraulic dampers used on vehicles today, providing an even more comfortable ride.

The eROT system is designed to respond quickly and with minimal inertia. As an actively controlled suspension, it adapts ideally to irregularities in the road surface and the driver’s driving style.

The new technology is based on a high-output 48V electrical system. As currently configured, its lithium-ion battery offers an energy capacity of 0.5kWh hours and peak output of 13kW. A DC converter connects the 48V electrical subsystem to the 12V primary electrical system, which includes a high-efficiency, enhanced output generator.

Initial test results are promising and its use in future Audi production models is therefore plausible.
