  • Method for braking a traction vehicle-trailer combination with reduced trailer braking force as a function of the response of the ABS of the traction vehicle
    Patent number: 9809206
    Abstract: A method and device for braking a traction vehicle-trailer combination with a traction vehicle and at least one trailer, in which a traction controller is provided for a brake system of the traction vehicle, and for a brake system of the at least one trailer, no traction controller is provided or a traction controller is provided for the axles which are present, but with a brake-slip-determining arrangement on fewer axles than the number of axles, in which (a) the trailer brake system is controlled by the traction vehicle brake system, and (b) during a braking it is determined whether there is a risk of the trailer swinging out as to the traction vehicle, or whether such swinging is imminent or is occurring, and (c) the braking force or the braking of the trailer is reduced if it has been determined in (a) that there is a risk of the trailer swinging out, or is imminent or is occurring, and (d) a risk of the trailer swinging out, or imminent or occurring swinging out of the trailer, as to the traction vehicle
