Abstract
A method controls a brake system of a vehicle combination. The switching valve in the second setting (anti-jackknifing braking function active) outputs a reservoir pressure into a trailer pressure line to actuate the trailer service brakes dependent on the anti-jackknifing braking demand. When service braking demand and anti-jackknifing braking demand are simultaneously present, an anti-jackknifing and a service braking ratio value are determined, a switchover criterion is checked dependent on the ratio values. The criterion is satisfied if the service braking ratio value exceeds a specified fraction of the anti-jackknifing braking ratio value when the anti-jackknifing braking function is active and falls below the specified fraction when the anti-jackknifing braking function is inactive; and, if the criterion is satisfied, the switching valve is switched over to activate the anti-jackknifing braking function and implement the anti-jackknifing braking demand, or to deactivate the anti-jackknifing braking function and implement the service braking demand.
