Method and apparatus for deactivating a hillholder function

A method for controlling a braking system of a motor vehicle, the method comprising:

• in order to prevent the vehicle from rolling away after a stopping action, establishing a first braking force value at at least one wheel of the vehicle, independently of a driver, and holding the first braking force value until a release condition exists;
• ascertaining a transverse variable characterizing a transverse motion of the vehicle;
• and
• as a function of the transverse variable, providing a release of a braking force even before the release condition exists,
• wherein a yaw rate is incorporated into the ascertaining of the transverse variable, and
• wherein the release condition is an expiration of a holding time interval of predefined length.

An apparatus for controlling a braking system of a motor vehicle, comprising:

• rollaway prevention means for preventing the vehicle from rolling away after a stopping action, in that a first braking force value is established at at least one wheel of the vehicle, independently of a driver, and is held until a release condition exists;
• ascertaining means for ascertaining a transverse variable characterizing a transverse motion of the vehicle;
• and
• braking force release means for providing, as a function of the transverse variable, a release of a braking force even before the release condition exists,
• wherein a yaw rate is incorporated into the ascertaining of the transverse variable, and
• wherein the release condition is an expiration of a holding time interval of predefined length.
