Patent number: 10814844Abstract: A braking controller and method in a towing vehicle towing one or more towed vehicles as a combination vehicle provides brake control of the one or more towed vehicles based on a level of braking force applied to the towing vehicle. A non-enhanced braking mode applies a first level of braking force to the towed vehicles in a predetermined reduced proportion relative to the level of braking force applied to the towing vehicle, and an enhanced braking mode applies a second level of braking force to the towed vehicles greater than the first level of braking force. The enhanced braking mode strategy is used unless trailer capability information reported by one or more the trailers fails to match against expected trailer capability information.Type: GrantFiled: September 15, 2017Date of Patent: October 27, 2020Assignee: Bendix Commercial Vehicle Systems LLCInventors: Phillip J. Kasper, Michael D. Tober, Claus Beyer, Joseph M. MacNamara, Subashish Sasmal

A non-enhanced braking mode applies a first level of braking force to the towed vehicles in a predetermined reduced proportion relative to the level of braking force applied to the towing vehicle, and an enhanced braking mode applies a second level of braking force to the towed vehicles greater than the first level of braking force. A controller deceleration command input receives a deceleration command signal which is compared against predetermined threshold deceleration rate value or against a current deceleration value being executed by the combination vehicle and, based on a result of the comparisons, either the enhanced or the non-enhanced braking modes are implemented by the controller.Type: GrantFiled: July 25, 2018Date of Patent: February 4, 2020Assignee: Bendix Commercial Vehicle Systems LLCInventors: Phillip J.

Patent number: 10343658Abstract: An apparatus and method are provided for determining the braking status of trailers and dollies in a multi-trailer vehicle train. A vehicle controller receives inputs from the vehicle to determine an estimate of the total vehicle mass from the dynamic response of the vehicle to an input such as application of engine torque, and to determine an estimate of the loads of the vehicle based on information provided from trailers and dollies communicating with the vehicle controller. A plausibility analysis is conducted to determine whether the estimates are within a tolerance range indicative of whether all of the trailers and dollies are communicating with the vehicle controller. If the vehicle controller determines that not all of the trailer and dolly anti-lock braking and/or stability control systems are available, the vehicle controller may in subsequent braking events command trailer and dolly brake application at a reduced level intended to avoid trailer and dolly wheel skidding.Type: GrantFiled: November 20, 2017Date of Patent: July 9, 2019Assignee: Bendix Commercial Vehicle Systems, LLCInventor: Michael D.

Patent number: 10150457Abstract: A valve module is provided for enabling a vehicle to control an autonomous event of the vehicle. The valve module comprises a relay valve, a first solenoid valve, and a second solenoid valve. A first control pressure can be delivered through the first solenoid valve and applied to a control port of the relay valve. In one embodiment, a second control pressure can be delivered through the second solenoid valve and combined with the first control pressure. The combined first and second control pressures are applied to the control port of the relay valve. In another embodiment, a second control pressure can be delivered through the second solenoid valve only when no first control pressure is delivered through the first solenoid valve.Type: GrantFiled: April 28, 2016Date of Patent: December 11, 2018Assignee: Bendix Commercial Vehicle Systems LLCInventors: David W Howell, Paul C Niglas, Michael D Tober, Gerhard Wieder
