1. A system for controlling a brake-based safety system of an automotive vehicle comprising:
- a transition controller generating a first control signal corresponding to a first control level;
a proportional-derivative controller generating a second control signal corresponding to a second control level;
an arbitration module coupled to the transition controller and the proportional-derivative controller, said arbitration module comparing the first control level and the second control level and then selecting the first control signal or the second control signal corresponding to a higher control level as a final control signal; and
the safety system coupled to the arbitration module, said safety system operated corresponding to the final control signal.

Abstract
A system 18 for controlling a safety system of an automotive vehicle has a first controller 76 generating a first control signal, a second controller 78 generating a second control signal and an arbitration module 80 coupled to the first controller 76 and the second controller 78. The arbitration module 80 chooses the higher of the first control signal and the second control signal to generate a final control signal. The safety system 38 is coupled to the arbitration module. The safety system 38 is operated in response to the final control signal.

13. A method of controlling a hydraulic safety system of an automotive vehicle comprising:
-
determining a vehicle roll angle;
in a transition controller generating a first control signal;
when the roll angle is greater than a threshold, generating a second control signal from a proportional-derivative controller;
comparing a first control level of the first control signal and a second control level of the second control signal to obtain a final control signal corresponding to a higher control level of the first control signal or the second control signal; and
controlling the hydraulic safety system in response to the final control signal. - View Dependent Claims (14, 15, 16)
