Patent ID: 8315772

Claim:
A method for shifting a braking assistant enabling function into an activatable state, the method comprising: after a termination of a braking assistant function, one of shifting the braking assistant enabling function, which enables re-triggering of the braking assistant function, into a non-activatable state and maintaining a non-activatable state; while the braking assistant enabling function is in the non-activatable state after the termination of the braking assistant function, determining, at various determination times, information about a hydraulic pressure at a predefined point in a hydraulic braking circuit; and after at least one predefined condition is met by the information, shifting the braking assistant enabling function into an activatable state; wherein the at least one predefined condition includes a magnitude of a slope of a decrease in the hydraulic pressure over time being greater than a predefined threshold steepness for a predefined number of determination times.
