An apparatus for controlling a pneumatic park brake actuation of a vehicle operable to tow a trailer comprises: a pressure supply terminal (1) to supply pressured air, a control line to parking brake actuators (28), a trailer control line (29.2), a control unit (10), a bistable valve (5), and a valve unit (3). The trailer control line (29.2) is configured to provide pressured air for a trailer braking unit of the vehicle. The control unit (10) is configured to provide an autonomous operation signal indicating a desired autonomous vehicle operation mode. The bistable valve (5) includes a first terminal (5a), a second terminal (5b), and a third terminal (5c), the third terminal (5c) being connectable to parking brake control line (28) and to the trailer control line (29.2), the bistable valve (5) being switchable in a first stable position (51) where the first terminal (5a) is connected with the third terminal (5c) and in a second stable position (52) where the second terminal (5b) is connected with the third terminal (5c). The valve unit (3) is coupled to the bistable valve (5), to a pressure sink (20) and to the pressure supply terminal (1) and is configured to receive the autonomous operation signal. The valve unit (3) is further operable to connect the first terminal (5a) with the pressure supply terminal (1), to connect the second terminal (5b) with a pressure sink (20), when no autonomous operation signal is received, and, upon reception of the autonomous operation signal, to interrupt the connection between the second terminal (5b) and the pressure sink (20).
