Abstract
The present invention relates to a vehicle wheel sensor apparatus and a method that determine if a vehicle wheel sensor is active or passive, while efficiently providing the necessary connectivity, power, and communication between the sensor and a controller, without requiring a change in controller hardware. For an active sensor, the apparatus provides power and receives speed signals, high frequency vibration or acceleration signals, or other analog signals. For a passive sensor, the apparatus receives speed signals.
