Claim 12:
13. The method as claimed in claim 11, wherein the secondary brake system (46, 46′) is utilized in an additional brake function, wherein the secondary brake system (46, 46′) assists a service brake system (30) of the vehicle (2), the method further comprising:
braking the vehicle (2) with the secondary brake system (46, 46′) when values of the brake value signal (SBW) are present that signal a brake request that is greater than a brake retardation of the vehicle that is manageable solely by the service brake system (30),
wherein the working pressure (pFSB) of the secondary brake system (46, 46′) is lowered along with an increasing value of the brake value signal (SBW), the brake value signal (SBW) increasing from a fixed initial value (SBW_Start) of the brake value signal (SBW), starting from a maximum working pressure (pFSB_max) in the case of a minimum value of the brake value signal (SBW), as far as a predefined working pressure (pFSB) in the case of a maximum value of the brake value signal (SBW).
