DARMSTADT, Germany—Vibracoustic GmbH has developed a range of noise, vibration and harshness solutions, specifically to address the emerging challenges of autonomous driving.
According to Vibracoustic, NVH likely will be a critical factor to acceptance and mass adoption of self-driving vehicles, as drivers and passengers will have a heightened perception of NVH issues in driverless cars.
"Once the driver becomes a passenger without the need to control the vehicle or focus on the road, their perception of noise, vibration and harshness are significantly enhanced," said Dr. Joerg Boecking, Vibracoustic's chief technology officer.
Vibracoustic has, therefore, developed solutions to address the two main causes of NVH issues: excitations from the road surface and from the vehicle's drivetrain and auxiliaries. For these internal excitations, Vibracoustic has a range of advanced mounts and bushings that mitigate vibrations transmitted through the axles and body to the seats and steering system.
By minimizing the effect of these inputs and isolating vibrations from the passengers, comfort is increased significantly, Vibracoustic noted.
Vibracoustic's product portfolio includes conventional rubber bushings to complex, hydraulic, switchable or even active mounting solutions, the company added.
For excitations coming from the road, Vibracoustic is offering switchable air springs, which are suitable for the transition to autonomous vehicles.
