    Abstract: Ein System und Verfahren zum Diagnostizieren und/oder Abschwächen der Auswirkungen eines nicht funktionierenden Bremsventils, das ausgestaltet ist zum Zuleiten eines druckbeaufschlagten Fluides zu einer Bremseinheit über eine Druckbereitstellungsleitung während automatischer Bremsvorgänge, beinhaltet ein Erfassen eines Zeitraumes einer Nichtbremsaktivität, ein Entlüften der Druckbereitstellungsleitung an die Atmosphäre während des Zeitraumes einer Nichtbremsaktivität, ein Überwachen eines Druckes in der Druckbereitstellungsleitung zum Erfassen einer Druckänderung infolge des Entlüftens und ein Erzeugen eines Fehlersignals, wenn eine erfasste Druckänderung einen Schwellenwert übersteigt. Das Druckmodulierventil kann periodisch angesprochen werden, sobald ein Fehler erfasst wird, um dessen Auswirkungen zu verringern.

    Abstract: A system and method are provided for improving the operational performance of a moving cement mixer vehicle with a rotatable mixing drum by automatically stopping the rotation of the mixing drum at select moments. The system may include a sensor adapted to deliver a signal indicative of an operational parameter, such as steering angle of the vehicle, and a processing unit adapted to receive the signal from the sensor and deliver a control signal based on the signal for stopping rotation of the mixing drum.

    Abstract: Various embodiments of a towing vehicle controller and methods for brake control of a towed vehicle are provided. In one embodiment of the present invention, a towing vehicle controller for providing brake control of a towed vehicle includes: a controller input for receiving a load signal indicative of a load of a towed and towing vehicle combination; a controller input for receiving a stability signal indicative of at least one of a yaw rate signal, a steering angle signal, and a lateral acceleration of the towing vehicle; and a controller input for receiving a deceleration signal indicative of an automated deceleration request. The control logic is capable of determining a comparison value prior to receiving the deceleration signal and after receiving the load signal and the stability signal, wherein the determination of the comparison value is based on the load signal and the stability signal received.
