Patent number: 11814055Abstract: A system for determining vehicle direction includes an active wheel speed sensor (aWSS), an exciter ring for inducing a change in a signal from the aWSS and a controller. The controller receives a first series of signals from the aWSS, compares them to an array of predefined signals and determines the direction of travel based on the first series of signals matching the array. The controller receives a second series of signals and determines the exciter ring has an anomaly in response to at least one signal in the second series of signals having a first variance. The controller updates the array of predefined signals to include a representation of the first variance to create an array of updated signals. The controller determines the direction of travel based on a subsequent series of signals matching one of the array of predefined signals and the array of updated signals.Type: GrantFiled: June 16, 2021Date of Patent: November 14, 2023Assignee: Bendix Commercial Vehicle Systems LLCInventors: Nianqing Zhou, Shu Yan Liu, Daniel P Zula, Thomas J Hayes

Patent number: 11787375Abstract: An installation system for an associated housing includes a sensor and a tool. The sensor includes: a barrel portion, a sensing end of the barrel portion, a non-sensing end of the barrel portion, an over-mold portion at the non-sensing end, and a wire extending from the non-sensing end. The tool includes a handle and an applicator secured to the handle. The applicator includes a first applicator portion, a second applicator portion, and a channel. When the over-mold portion of the sensor is proximate to a channel opening and the channel opening is blindly inserted into the associated housing opening, a force applied to the handle along an angle relative to the longitudinal axis of the handle frictionally seats the sensor in the associated housing.Type: GrantFiled: June 8, 2021Date of Patent: October 17, 2023Assignee: BENDIX COMMERCIAL VEHICLE SYSTEMS LLCInventors: Nianqing Zhou, Daniel P Zula, Shu Yan Liu

Patent number: 11472381Abstract: A system and method for controlling a vehicle wheel brake are provided. The system includes one or more inertial sensors disposed within a handle coupled to, and configured for movement relative to, a fixed reference frame in the vehicle between a neutral position and one or more input positions. Each sensor generates an inertial measurement signal indicative of a value of an inertial measurement associated with movement of the handle and sensor between the neutral and input positions. A controller receives the signals, identifies a turning point in a rate of change of the value of one of the inertial measurement indicated by the signals, and generates an operator command signal when the value meets a predetermined condition. The operator command signal is configured to cause one of application or release of the wheel brake.Type: GrantFiled: September 11, 2019Date of Patent: October 18, 2022Assignee: Bendix Commercial Vehicle Systems LLCInventors: Daniel P.
