Patent ID: 7845739

Claim:
A brake regulation system for a motor vehicle, comprising: an electronic control unit, by which an automatic parking brake function is activatable when the motor vehicle is stationary and deactivatable upon reaching a predetermined triggering condition; wherein the electronic control unit determines in a wheel selective manner a coefficient of friction of a roadway at a location of the motor vehicle being held stationary via the automatic parking brake function; wherein when different coefficients of friction exist at right and left wheels of at least one driven axle of the motor vehicle, the predetermined triggering condition for deactivating the automatic parking brake function is adapted so that brake pressure is maintained for a longer period of time; and wherein the triggering condition is an overshooting of a defined drive torque threshold, said drive torque threshold being doubled in the presence of a coefficient of friction of substantially zero on one side in relation to a drive torque threshold in the case of approximately identical coefficients of friction at the left and the right wheels of the at least one driven axle.
