The invention relates to a control device for controlling at least the parking brake of a towing vehicle of a towing vehicle/trailer combination, said parking brake comprising at least one spring brake cylinder, and for controlling the service brake of a trailer of the towing vehicle/trailer combination, containing at least the following: a) a compressed air supply connection (1) which can be connected to a compressed air storage container, b) an air quantity boosting valve device (9), the inlet (9.2) of which can be connected to the compressed air supply connection (1), the outlet (9.3) of which can be connected to a working connection (28) with the at least one spring brake cylinder, and which has a pneumatic control inlet (9.1) for supplying a control pressure in order to control the pressure at the outlet (9.3) of the air quantity boosting valve device (9), c) an electrically actuatable bistable valve (5) with an inlet (5.1) which can be connected to the compressed air supply connection (1) and to an outlet (5.2) that can be connected to the control inlet (9.1) of the air quantity boosting valve device (9), the outlet (5.2) of the bistable valve being connectable either to the bistable valve inlet (5.1) or to a pressure sink (5.3), d) an electronic control unit (10) which is electrically connected to the bistable valve (5) and which controls the bistable valve (5), and e) at least two ventilatable or evacuatable connections (29.1, 29.2) for a trailer control valve device which controls the service brakes of the trailer, one connection (29.1) of the connections (29.1, 29.2) being ventilated and the other connection (29.2) of the connections (29.1, 29.2) being evacuated when the vehicle is parked and one connection (29.1) and the other connection (29.2) being ventilated when the vehicle is traveling, wherein f) the inlet (5.1) of the bistable valve (5) is connected to a connection (29.1). According to the invention, g) the outlet (5.2) of the bistable valve (5) is directly and constantly connected to the control inlet (9.1) of the air quantity boosting valve device (9), and h) a valve device (7; 7') is provided which can be at least partly electrically controlled by the control unit (10) and which is designed to connect the other connection (29.2) to the inlet (5.1) or to the outlet (5.2) of the bistable valve (5) or to a pressure sink (7.12').
