Suspension of functions

In the interest of avoiding irritation when cornering at high speed, the active-seat function is stopped immediately in the event of excessive lateral acceleration.

The lateral-acceleration signal comes from the yaw-rate sensor. The Integrated Chassis Management issues the signal via the FlexRay.

The central gateway module transfers the signals to the K-CAN. This allows the seat module to receive the signal for the vehicle's lateral acceleration. The seat module cancels activation when a defined threshold is exceeded. The function indicator however remains lit.

The active seat is switched on again when the lateral-acceleration value drops again.
