Patent number: 11767004Abstract: A system on a tractor for controlling trailer service brakes comprises a manually operated trailer brake switch, a first electropneumatic valve in communication with a pressure source and a controller. The controller has an input communicating with the trailer brake switch, an output communicating with the electropneumatic valve and control logic. The control logic receives an input from the trailer brake switch indicating a driver's request to apply the trailer service brakes of the combination vehicle, determines if a predetermined condition exists and transmits a signal to the output to the electropneumatic valve. The electropneumatic valve transmits pressure to a trailer service control line to actuate the trailer service brakes in response to the trailer brake switch and existence of the predetermined condition.Type: GrantFiled: September 4, 2020Date of Patent: September 26, 2023Assignee: BENDIX COMMERCIAL VEHICLE SYSTEMS LLCInventors: Phillip J Kasper, David J Taneyhill, Paul C Niglas, Gerhard Wieder, Arnav Vasudev, Christopher H Hutchins

Patent number: 11724676Abstract: A trailer control valve for a tractor includes a body defining a supply port and first and second delivery ports. The supply port is configured for fluid communication with a fluid source on the tractor. The first and second delivery ports are configured for fluid communication with glad-hand connectors through which fluid is supplied from the tractor to a trailer. A pressure sensing solenoid receives fluid signal from each of the first and second deliver ports and selectively passes fluid signal therefrom to a pressure sensor as a function of a brake control signal received by a controller that controls the pressure sensing solenoid.Type: GrantFiled: November 5, 2019Date of Patent: August 15, 2023Assignee: Bendix Commercial Vehicle Systems LLCInventors: Paul C.
