Wheel Speed Sensor Direction Detection Without Physical Key

The patent replaces the mechanical physical key alignment system with an electronic/software-based solution. The controller learns to interpret sensor signals by associating them with direction information from other sources (yaw rate sensor, transmission controller), eliminating the need for mechanical alignment keys and enabling both passive and active sensors to provide directional information through software interpretation rather than mechanical configuration

The patent makes the mounting structure universal by enabling it to accommodate both passive and active wheel speed sensors with the same physical interface. The controller's learning algorithm universally processes signals from either sensor type, and the system universally accepts direction information from multiple sources (yaw rate sensor, transmission controller, or user input), creating a multi-functional system that works across different sensor types and vehicle configurations

The patent introduces intermediary sources of direction information (yaw rate sensor, transmission controller, or user input during testing) that mediate between the passive sensor and the controller. The controller uses these intermediary direction signals to learn and interpret the passive sensor's output patterns, thereby deriving directional information from sensors that originally cannot provide it independently

The patent implements a feedback mechanism where the controller receives direction information from external sources, uses it to interpret sensor signals, and then can determine wheel rotation direction. The system continuously learns by comparing sensor signals with known direction states from other vehicle systems, creating a closed-loop learning process that enables passive sensors to provide directional data
