Patent number: 11475776Abstract: Dynamic braking capability of a combination vehicle including a tractor and at least one trailer is provided based on a distribution of the load carried by the combination vehicle. Load distribution is determined directly using load sensors disposed at wheel pairs of the tractor and trailer(s) or indirectly by using a load sensor located at the drive axle of the tractor together with engine torque and vehicle speed signals for determining gross vehicle mass. A database having sub-databases therein each storing stopping distance calculation results for a corresponding combination vehicle type e.g. 5-axle single or 8-axle double, is indexed by using the determined load distributions for providing the dynamic braking capability based on the vehicle type and its load distribution. The database may also be indexed using Axle Load Allocation Factor that is calculated based on a mathematical combination of drive, steering, and gross trailer axle loading.Type: GrantFiled: December 10, 2019Date of Patent: October 18, 2022Assignee: Bendix Commercial Vehicle Systems LLCInventors: Subashish Sasmal, Phillip J. Kasper, Jeffrey M. Carbaugh

Patent number: 11318920Abstract: A brake controller in a vehicle determines braking profiles that may be exercised while operating the vehicle in autonomous or semi-autonomous conditions to decelerate the vehicle based on received commands or that may be exercised automatically in the event of a failure in a communication network of the vehicle or in other systems or components of the vehicle. The braking profiles decelerate the vehicle according to a deceleration profile. The execution of the deceleration profile may be initiated by a single command message received by the brake controller or it may be determined by the brake controller based on vehicle information. A safe state deceleration profile may be preselected by the controlling devices before the occurrence of a failure or an emergency situation, and then executed by the brake controller upon the occurrence of a failure or emergency.Type: GrantFiled: February 28, 2020Date of Patent: May 3, 2022Assignee: BENDIX COMMERCIAL VEHICLE SYSTEMS LLCInventors: Nicholas A. Broyles, Subashish Sasmal, Thomas S. Miller, Jr., Andrew L. Kennedy, Phillip J. Kasper

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.

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.

Publication number: 20180208164Abstract: A controller for a driver assistance system comprises an output for transmitting a braking control signal and control logic. The control logic is capable of identifying a target vehicle, determining an intervention zone and determining an edge zone. The controller will transmit the braking control signal to request activation of the brakes on the host vehicle in response to the edge zone being equal to or less than zero and the target vehicle being within the intervention zone.Type: ApplicationFiled: January 24, 2017Publication date: July 26, 2018Inventors: Jeffrey M.
