Overview

Damper technology is evolving from passive to active control. At Infineon, we provide motor control chipsets for designing 48 V and high-voltage actuators, scalable from 400 V to 800 V. In addition, our sensor solutions enable the monitoring of both road conditions and vehicle motion, supporting real-time adjustment and paving the way for predictive suspension control.

Benefits

  • Scalability and interoperability
  • Adaptability via software OTA
  • Dependable quality and performance
  • Covers 12 V, 48 V, and high-voltage

About

Advanced suspension systems improve comfort, handling, and safety

Active suspension control (ASC) is a technology that uses sensors and actuators to actively control the suspension of a vehicle. This can be used to improve ride comfort, handling, and safety.

There are a number of different applications for ASC:

  • Ride comfort: ASC can be used to improve ride comfort by reducing vibrations and oscillations. This can be done by adjusting the stiffness of the suspension or by using actuators to actively dampen the vibrations.
  • Handling: ASC can be used to improve handling by reducing body roll and improving the responsiveness of the suspensions. This can be done by adjusting the stiffness of the suspensions or by using actuators to actively control the roll of the vehicle.
  • Safety: ASC can be used to improve safety by reducing the risk of accidents. This can be done by improving the driver's ability to control the vehicle in difficult conditions, such as when driving on wet or icy roads.
Infineon's portfolio addresses low and high-voltage suspension systems

Infineon supports a range of suspension technologies—including air, hydraulic, and magnetic systems—across multiple voltage classes. Semi-active suspensions typically operate below 48 V, while active suspensions require 48 V or higher voltage architectures. To address these diverse requirements, Infineon provides a comprehensive motor control portfolio for both low- and high-voltage systems.

Seamless integration and highest-possible safety standards

We recognize that chassis applications are some of the most important safety functions of a vehicle and we translate that into a system level approach to functional safety with products that are ISO 26262-compliant and developed together to meet the strictest standards in safety and robustness.

With a proven track record and years of experience in the automotive sector, Infineon is the right partner. Our components have been designed and tested to ensure they work seamlessly and fulfill the highest-possible safety standards. Since our chipset is aligned in-house, you can count on its interoperability to ensure safety while reducing your development effort. Thanks to a small footprint and integrated features, our solution contributes to a lower BOM. 

Furthermore, our chipset is suitable for OEMs who want to scale platform solutions across models to increase cost efficiency, from fail-safe to fully redundant fail operational and high availability solutions. Last but not least, there’s the peace of mind you gain knowing that all components are manufactured according to Infineon’s high automotive quality standards.
