Active suspension control

Active and semi-active suspension systems are a desirable feature in luxury and sports cars, with comparatively low-production volumes.

Overview

In contrast to passive suspension systems, which rely on springs and shock absorbers to dampen the effects of bumps and road irregularities, active suspension systems use sensors to monitor the road surface and the vehicle's motions. This information is used to control actuators that apply forces to the suspension components, which allows the system to actively adjust the suspension in real time to provide a smoother ride and improved handling.

Benefits

  • Scalability and interoperability
  • Highest design flexibility
  • Single source of chipset solution
  • Adaptability via software OTA
  • Easy design-in; fast time to market
  • Dependable quality and performance

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.
Sense, compute, and power devices support various partitioning

We have over two decades of expertise in chassis application solutions, know how of safe motor control, dependable products, technical documents, and evaluations boards.

With that we cover every major socket in chassis actuators to enable easy design-in and fast time to market:

  • Powerful and scalable chipset featuring a small footprint
  • Field-proven interoperability
  • Support of fail-safe and fail-operational systems
  • Harmonized safety concept that focuses on power supply and microcontrollers
  • Adaptability via software: suits a range of driving modes and car models
  • Designed for a wide range of applications, from ADAS to actuators

For all your development needs, Infineon provides the full range of ICs, from safety microcontrollers to power supplies, bridge drivers, world-class MOSFETs, and sensors. Find out what is possible with our components to enhance your project.

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.
