Towed vehicles can be extremely heavy. Accordingly, it is too much of a burden to the braking system of a towing vehicle to not have brakes on the towed vehicle. Controlling the brakes of the towed vehicle must be accurately applied otherwise undesirable conditions can be created. There is a need for a method for controlling braking of a towed vehicle. This method comprises receiving a first signal via a communication bus of a towing vehicle, the first signal relating to at least one operating condition of at least one the towing vehicle and a towed vehicle, sending a second signal to brakes of the towed vehicle, the second signal based on said first signal.

An assistance System for a vehicle for providing an emergency stop assistance function that includes an execution device to execute the emergency stop assistance function using at least one of a plurality of activation stages; a detection device for automatic detection of driver inactivity, in order to activate the emergency stop assistance function using a first stage selection of the activation stages; a triggering device for monitoring an operating element of an electrical parking brake or a parking lock of a transmission of the vehicle, in order to activate the emergency assistance function using a second stage selection of the activation stages, which differs from the first stage selection, in the case of a manual activation of the operating element.

A drum brake module for motor vehicles, the drum brake module being driven by an electric motor and having at least one parking brake function, includes an electromechanical cable pull actuator which is fastened on the anchor plate with the aid of an adapter. The adapter is designed as a one-piece, thin walled frame having at least one fastening flange for receiving the cable pull actuator and is held in place on the anchor plate.

Provided is a non-excitation operable electromagnetic brake that includes a manually operable rotary cam for switching over a rotor to a brake releasing state, but that allows easy recognition of switchover to the brake released state via an operation reaction force and that also allows reliable keeping of the rotary cam under its acting state. Even when an electromagnet is under a non-excited state, when a rotary cam is rotatably operated to an acting position, an acting portion of the rotary cam slidably operates a rotor via a releasing plate to a brake releasing state against springs. The acting portion of the rotary cam is formed linear along a tangent at a center of the acting portion with respect to a rotary cam rotational direction.

A utility vehicle control device for a parking brake device of a trailer vehicle includes a pneumatic supply connection, a control connection for controlling a spring brake cylinder, a directly manually actuatable parking valve, a first connection line and a control valve for controlling the parking valve. The parking valve is arranged in the first connection line, and wherein as a result of the parking valve, the supply connection and the control connection can be connected via the first connection line. A control line branches from the first connection line. The control line is connected to a first pneumatic control input of the control valve, wherein the control valve has a second pneumatic control input. In the event of an unexpected reduction in operating pressure in the first connection line and/or in the control line, the control valve can be controlled by the first or second control input of the control valve such that a switching state of the parking valve can be pneumatically controlled by the control valve independently of an operating state of the supply connection, whereby the control connection is ventilated by the parking valve.
