1. Core Function: Real-Time Monitoring of QR019's Hydraulic and Temperature Parameters

As the core sensing component of the QR019 transmission, the sensor simultaneously monitors two key parameters: hydraulic pressure and transmission oil temperature. Installed at the QR019 transmission's main oil pressure port and oil temperature detection point, it converts the detected hydraulic pressure (0-2800 kPa) into a 0-5V analog signal and the oil temperature (-30°C to 140°C) into a digital signal, transmitting both to the QR019 ECU. For example, during the QR019 transmission's 1-2 gear shift, the sensor monitors the pressure change of the No.1 clutch cylinder (from 200 kPa to 1800 kPa) and the oil temperature rise (usually ≤5°C per shift), ensuring the ECU adjusts the hydraulic valve's oil supply in real time. This function prevents the QR019 transmission from experiencing issues such as insufficient pressure (leading to clutch slippage) or overheating (causing oil viscosity reduction).

2. Supporting QR019's Adaptive Gear-Shifting Control

The accurate data provided by the sensor is the basis for the QR019 transmission's adaptive gear-shifting function. The QR019 ECU stores multiple sets of gear-shifting maps (for urban, highway, and heavy-load scenarios), and the sensor's real-time pressure and temperature data help the ECU identify the current driving condition. For instance, when the sensor detects that the transmission oil temperature exceeds 120°C (due to long uphill driving with a heavy load), the ECU switches to the high-temperature gear-shifting map—delaying upshifts and increasing the clutch engagement pressure to avoid overheating. When the sensor detects frequent small fluctuations in hydraulic pressure (indicating urban stop-and-go driving), the ECU adjusts to the economic gear-shifting map, optimizing the shift timing to reduce fuel consumption. This adaptive control aligns with the QR019 transmission's focus on both power and fuel efficiency.
