A method for the automatic actuation of brakes in a trailer vehicle with antilock control, in particular for protection from overturning, wherein wheel revolution rates on wheels with antilock control are continuously monitored and analyzed by the trailer vehicle, characterized by the following features: a) determining a lateral acceleration a Q and a longitudinal acceleration a L of the vehicle, b) on exceeding a predefined, critical lateral acceleration a Qkrit, carrying out an automatic braking process comprising: b1) - increasing a brake pressure on a side of the trailer vehicle on an inside of a turn in small steps of in particular 0.1 - 0.2 bar, b2) - checking in each step whether a longitudinal acceleration limit a Lkipp is reached, b3) - checking in each step whether wheels on the inside of the turn lock or the antilock control engages for wheels on the inside of the turn, wherein b31) - if wheels on the inside of the turn lock or the antilock control engages for wheels on the inside of the turn before a Lkipp is reached, the method further comprises starting deceleration braking at least on a side of the trailer vehicle on an outside of the turn, b32) - if a Lkipp is reached without wheels on the inside of the turn locking or the antilock control engaging for wheels on the inside of the turn, the method further comprises terminating the braking process. a) determining a lateral acceleration a Q and a longitudinal acceleration a L of the vehicle, b) on exceeding a predefined, critical lateral acceleration a Qkrit, carrying out an automatic braking process comprising: b1) - increasing a brake pressure on a side of the trailer vehicle on an inside of a turn in small steps of in particular 0.1 - 0.2 bar, b2) - checking in each step whether a longitudinal acceleration limit a Lkipp is reached, b3) - checking in each step whether wheels on the inside of the turn lock or the antilock control engages for wheels on the inside of the turn, wherein b31) - if wheels on the inside of the turn lock or the antilock control engages for wheels on the inside of the turn before a Lkipp is reached, the method further comprises starting deceleration braking at least on a side of the trailer vehicle on an outside of the turn, b32) - if a Lkipp is reached without wheels on the inside of the turn locking or the antilock control engaging for wheels on the inside of the turn, the method further comprises terminating the braking process. b1) - increasing a brake pressure on a side of the trailer vehicle on an inside of a turn in small steps of in particular 0.1 - 0.2 bar, b2) - checking in each step whether a longitudinal acceleration limit a Lkipp is reached, b3) - checking in each step whether wheels on the inside of the turn lock or the antilock control engages for wheels on the inside of the turn, wherein b31) - if wheels on the inside of the turn lock or the antilock control engages for wheels on the inside of the turn before a Lkipp is reached, the method further comprises starting deceleration braking at least on a side of the trailer vehicle on an outside of the turn, b32) - if a Lkipp is reached without wheels on the inside of the turn locking or the antilock control engaging for wheels on the inside of the turn, the method further comprises terminating the braking process. b31) - if wheels on the inside of the turn lock or the antilock control engages for wheels on the inside of the turn before a Lkipp is reached, the method further comprises starting deceleration braking at least on a side of the trailer vehicle on an outside of the turn, b32) - if a Lkipp is reached without wheels on the inside of the turn locking or the antilock control engaging for wheels on the inside of the turn, the method further comprises terminating the braking process.
