The Hall sensor is electrically connected with the gear shifter controller and used for detecting whether the gears are shifted in place. After the gear shifting operation is completed, the detected detection value is sent to the upper computer by the Hall sensor through the gear shifter controller, and the upper computer detects whether the detection value of the Hall sensor meets the preset requirement or not, so that whether gear shifting is in place or not is judged.
The gear values indicate the gears in which the vehicle is located, such as P, R, N, and D.
