1. Dynamic Fine-Tuning of Oil Pressure for Multiple Working Conditions
Targeting diverse usage scenarios of high-end models (urban congestion, high-speed cruising, mountain climbing, sport mode, comfort mode), it is equipped with a "four-stage pressure compensation valve core" that enables stepless oil pressure regulation within the range of 0.4-2.6MPa. For example, during low-speed shifting in comfort mode, it outputs low oil pressure (0.4-0.9MPa) and further reduces impact through the "oil damping chamber" to improve riding quietness (transmission noise ≤ 45 decibels); during rapid acceleration in sport mode or climbing (slope ≥ 20°), it automatically increases the oil pressure to 2.0-2.6MPa to enhance clutch engagement rigidity and transmission tension of planetary gear sets, avoiding power slipping (e.g., vehicle speed fluctuation ≤ 0.5km/h during steep hill starts); during high-speed cruising, it finely adjusts the oil pressure through a dynamic compensation algorithm (fluctuation range ≤ 0.02MPa) to reduce transmission system vibration (vibration amplitude ≤ 0.08mm), meeting the high requirements for driving quality of high-end models.
2. Full-Lifecycle Intelligent Fault Monitoring and Protection
Equipped with a high-precision current detection chip (detection accuracy ± 0.005A), NTC temperature sensor (temperature measurement accuracy ± 0.5℃), and valve core stroke feedback module, it can real-time monitor its own working status. When abnormal current (overcurrent ≥ 2.8A or undercurrent ≤ 0.5A), working temperature exceeding 135℃, or valve core jamming (action delay > 0.07 seconds) caused by hydraulic oil impurities (particle size ≥ ISO 17/14) is detected, it will immediately send fault codes (e.g., P0976 Solenoid Valve Pressure Control Abnormality, P0872 Oil Pressure Sensor Fault) to the TCU, triggering a three-fold protection mechanism: first, it cuts off its own redundant power supply to prevent coil burnout (avoiding the impact of circuit faults on the overall operation of the transmission); second, it assists the TCU in switching to "high-end limp mode" (locked in 4th-5th gears to avoid jitter caused by frequent low-gear shifting); third, it activates the oil self-cleaning cycle to flush impurities on the valve core through high-pressure oil flow, reducing the impact of short-term faults on the driving experience and providing guarantee for the vehicle's safe return or maintenance, which aligns with the "low maintenance and high reliability" characteristics of high-end models.
