Abstract: A method for carrying out a distance-regulating or speed-regulating function for a single-track motor vehicle. An activated distance-regulating or speed-regulating function can be deactivated by the driver through actuation of a brake operating element, if the actuation intensity of the brake operating element exceeds a first threshold value. The presence of a collision risk is ascertained by an environmental sensor system. When there is a risk of collision, an emergency braking assistance function is activated through the actuation of the brake operating element by the driver with an actuation intensity exceeding a second threshold value. The second threshold value is lower than the first threshold value. The activated distance-regulating or speed-regulating function is continued independently of the driver after the termination of the emergency braking assistance function, with the settings that were present before the activation of the emergency braking assistance function.
