Chassis domain control
A chassis domain controller enables central, more efficient, and better coordinated control of chassis functions, updatable with new features.
A chassis domain controller (CDC) is a single ECU that is responsible for controlling multiple chassis-related subsystems in a vehicle. These can include the braking, steering, suspension, and active safety systems, such as electronic stability control. The CDC uses a variety of sensors to monitor the status of these subsystems and to adjust as needed to ensure safe and efficient operation with many advantages over distributed ECUs.

Highly effective chassis domain controller solutions
A chassis domain controller uses a variety of sensors to monitor the status of the chassis components, ensuring that they are operating properly, and implementing advanced safety features. It can also be used to improve a vehicle's performance. It can be used to adjust the stiffness of the suspension or the amount of power that is sent to each wheel. This can help to improve the vehicle's handling and acceleration. Finally, it can also be used to improve a vehicle's fuel efficiency by monitoring the status of the chassis components and adjusting their operation accordingly.
Some benefits of using a chassis domain controller are:
- Providing a high-performance, scalable, and safe computing platform which already includes the sensor cluster with all its multi-axle inertia sensors
- Allowing a cost-efficient x-check and fusion of the inertia sensor signals, as well as highly efficient and safe computing of the vehicle dynamic model
- Consequently, the chassis domain control unit represents a promising approach to efficiently coordinating functions such as VSC, semi-active suspension, and drivetrain, especially when four-wheel drive with torque vectoring is required.
