  • Shaft rotation speed and direction sensing
    Patent number: 11953089
    Abstract: A transmission system associated with a vehicle includes a shaft to rotate about an axis of rotation. The shaft is coupled to a gear set. The transmission system includes a target wheel to be coupled to the gear set and to rotate with the gear set. The target wheel includes at least one void. The transmission system includes a giant magnetoresistance (GMR) sensor spaced apart from the target wheel by a gap. The giant magnetoresistance (GMR) sensor is configured to observe the at least one void of the target wheel to determine a rotation speed of the shaft based on a giant magnetoresistance (GMR) effect. The transmission system further includes a rotating shell located in the gap between the target wheel and the giant magnetoresistance (GMR) sensor.
