A method/device for controlling a traction vehicle-trailer brake device, a trailer with an unactivated service brake is detected, and when a predetermined pushing effect is reached/exceeded a trailer brake system is activated to generate a braking force when the service brake is unactivated, in which the first parameter is a) consumption of an operating medium, and/or b) torque generated by a drive machine/driven wheel, and/or c) signal representing the traction vehicle/trailer's longitudinal deceleration, and/or d) the speed/acceleration at which an activation element is activated toward lower velocities, and/or e) a difference/quotient of a target traction vehicle speed, and an actual traction vehicle speed is used if the traction vehicle having an infinitely variable transmission, and provides infinitely variable adjustment of the transmission ratio, and f) the control device detects that the predetermined pushing effect of the trailer is reached/exceeded if a first parameter predetermined limiting value is reached/exceeded.
