Patent number: 11724672Abstract: A system controlling an electronic parking brake of a vehicle includes an input device receiving an input pattern from an operator and a parking brake controller receiving the input pattern from the input device. The parking brake controller determines if the input pattern is a respective predetermined pattern for setting the electronic parking brake to one of a primary mode and a secondary mode. If the parking brake controller determines the input pattern is the predetermined pattern for setting the electronic parking brake to the secondary mode, the parking brake controller transmits an electronic control signal for releasing the electronic parking brake until a subsequent input pattern received by the input device is the predetermined pattern for setting the electronic parking brake to the primary mode.Type: GrantFiled: November 19, 2020Date of Patent: August 15, 2023Assignee: BENDIX COMMERCIAL VEHICLE SYSTEMS LLCInventors: Christopher H Hutchins, Meviltan Mendis, Ron R Stahl, Srikiran Kosanam, Girish Barade

Patent number: 8892326Abstract: A tool for configuring a replacement electronic control unit for a vehicle is provided. The tool includes a computer storage medium having a computer program encoded thereon which may be stored on an electronic module or installed on a computing device that connects to a communications bus in the vehicle. The program includes code for accessing a first memory associated with an original electronic control unit for the vehicle, retrieving a configuration for the original electronic control unit from the first memory, associating the configuration with a vehicle identification number associated with the vehicle in a second memory remote from the vehicle and downloading the configuration from the second memory to a third memory associated with the replacement electronic control unit for the vehicle.Type: GrantFiled: October 10, 2011Date of Patent: November 18, 2014Assignee: Bendix Commercial Vehicle Systems LLCInventors: Timothy J. Frashure, Ron R. Stahl

Publication number: 20120296543Abstract: A vehicle, air brake system is presented with an improved service work brake arrangement. The arrangement may provide a service work brake function or both a service work brake function and a parking brake function for the vehicle. The arrangement may provide an improved service work brake arrangement disposed within a housing for reducing the number of components and plumbing required to achieve this functionality versus prior known systems. The arrangement may utilizes a pneumatic latching valve to deliver pressurized air for applying a vehicle's service brakes. The pneumatic latching valve opens upon receiving a pneumatic control signal from an electronically controlled valve and closes upon receiving a pneumatic control signal from another source. In addition, a controller and control logic may be provided for controlling the arrangement.Type: ApplicationFiled: August 6, 2012Publication date: November 22, 2012Applicant: BENDIX COMMERCIAL VEHICLE SYSTEMS LLCInventors: Matthew E. Rogers, Mark A. Bennett, Ron R. Stahl, Michael D. Tober, Kenneth A. Grolle, Richard J. Conklin, Timothy J. Frashure, David W. Howell

Patent number: 7976040Abstract: A system and process for controlling vehicle loading on a multi-axle vehicle and improving maneuverability is disclosed. The system includes a reservoir of pressurized air and associated leveling valve that uses a relay valve to improve refill times when the vehicle returns from a dump mode operation to normal operation. The process reduces pressure in one or more of the axles when maneuvering the vehicle at predetermined slow speeds and maintaining that first predetermined pressure while the other axle(s) is at a greater pressure than the first axle. By preventing complete exhaustion of pressure from the suspension system, restoring air pressure is attained more quickly. Also, use of a relay valve enables higher flow rates to improve the refill time of the pneumatic suspension system after the dump operation.Type: GrantFiled: April 14, 2010Date of Patent: July 12, 2011Assignee: Bendix Commercial Vehicle Systems, LLCInventors: Ron R. Stahl, Charles E. Eberling, John G. Nosse, John V. Ripley
