Observer based diagnosis of roll rate sensor

In the area of passive safety, the vehicle roll dynamic plays a very important role, especially when the vehicle tends to roll over. The danger of rolling over can early be recognized by the rollover sensing sensors. The rollover sensing system (ROSE) only works successfully, if all these sensors are faultless. One of these essential sensors is the roll rate sensor. The aim of this contribution is to present a new concept for monitoring the roll rate sensor signal. Investigations of the developed concept are carried out in a virtual vehicle. Finally, the car test results are demonstrated and discussed.
