AI Technical Summary
The existing technology lacks a diagnostic solution for loose connection faults in the AMT gear selection position sensor circuit, which leads to gear shifting failures and vehicle safety hazards.
A fault diagnosis and handling method for a gear selection position sensor is provided. By acquiring parameters such as the current and target gear, actuator position, oil temperature and speed difference, the voltage and position change rate of the sensor are determined, a loose connection fault is identified, and a fault handling process is used to ensure successful gear shifting.
Effectively identify and handle faulty gear selector position sensors, reduce gear slippage, improve shift success rate, and ensure normal vehicle operation under fault conditions.
