1.Advanced Transmission Control for Hybrid & DCT Systems
As a core control unit for Chery's advanced powertrains, it receives real-time data from ECU, HCU, and transmission sensors (speed, pressure, temperature, torque). It regulates clutch engagement/disengagement, gear shifting timing, and torque distribution between engine and electric motor (for hybrids). For DCT systems, it synchronizes the operation of dual clutches to ensure rapid, jitter-free gear changes.
2.Adaptive Gear Shift Optimization
Equipped with machine learning algorithms that analyze driver behavior (e.g., aggressive vs. gentle throttle input) and road conditions (via GPS and vehicle dynamics sensors). It dynamically adjusts shift points: in "Sport" mode, it delays upshifts for higher power; in "Eco" mode, it prioritizes early upshifts for fuel efficiency; on slopes, it holds gears to prevent frequent shifting—adapting to individual driving styles and road scenarios.
3.High-Speed Data Communication & Coordination
Features a CAN FD interface (data transfer rate up to 8Mbps, 10x faster than standard CAN) for seamless communication with ECU, HCU, and vehicle infotainment system. It transmits real-time transmission status (gear position, clutch temperature, fault codes) and receives control commands, enabling coordinated operation between powertrain components—e.g., adjusting transmission timing during regenerative braking to maximize energy recovery.
4.Intelligent Fault Diagnosis & Predictive Maintenance
Beyond basic fault detection, it uses predictive analytics to identify potential failures (e.g., early clutch wear, solenoid degradation) based on historical operating data. It logs detailed fault codes (compliant with ISO 15031) and transmits predictive maintenance alerts to the vehicle's dashboard and connected service platforms, allowing proactive repairs before major failures occur—reducing unplanned downtime.
5.Regenerative Braking Coordination (for Hybrids)
Exclusive to hybrid applications, it coordinates with the HCU to adjust transmission parameters during regenerative braking. It optimizes clutch disengagement timing and gear selection to maximize the electric motor's regenerative efficiency, converting more kinetic energy into electrical energy for the battery—extending the vehicle's electric driving range.
1.Enhanced Model Compatibility for Advanced Transmissions
Beyond Chery's mainstream models, it is optimized for Chery's latest 7-speed 湿式 dual-clutch transmissions (DCT) and hybrid transmission systems. It fully complies with the upgraded electrical communication protocols (CAN FD) and hydraulic control parameters of these advanced powertrains, avoiding compatibility issues like signal dropouts or control lag that may occur with lower-series components, ensuring seamless synergy with hybrid power units and high-torque DCTs.
2.Superior Durability for Extreme Operating Conditions
The housing adopts die-cast magnesium alloy (lighter than aluminum by 30%) with a ceramic coating, resisting temperatures up to 180°C and vibration up to 40g—ideal for hybrid vehicles' frequent start-stop cycles. Internal solenoid valves use diamond-like carbon (DLC) coated cores, reducing wear by 50% compared to the BK series. The MTBF (Mean Time Between Failures) exceeds 15,000 hours, meeting the durability standards of premium automotive components.
3.Next-Gen Precision Control & Responsive Performance
Leveraging a 32-bit high-speed microcontroller (processing speed 50% faster than BK series) and adaptive control algorithms, it achieves a response time of ≤30ms to transmission signals. Tolerances for key mating parts are controlled within ±0.005mm via ultra-precision CNC machining, ensuring shift shock <0.1g—delivering smoother gear transitions even during aggressive driving (e.g., rapid acceleration, downhill deceleration).
4.Energy Efficiency Optimized for Hybrid Systems
Tailored for hybrid powertrains, it features a low-power standby mode (current ≤80mA at 12V DC) and intelligent power management. It coordinates with the hybrid control unit (HCU) to adjust transmission parameters during electric-only, hybrid, and regenerative braking modes, reducing overall vehicle energy consumption by 8% compared to using standard transmission control components.
5.Comprehensive Intelligent Protection Mechanisms
Upgraded with multi-dimensional protection: over-voltage (18V max) and reverse-polarity protection for electrical circuits, dual-temperature sensors (monitoring both component and transmission fluid temperature) with thermal shutdown at 185°C, and short-circuit protection for all actuator outputs. It also adds a "limp home" mode that maintains basic transmission functionality in case of critical faults, preventing sudden power loss and ensuring driving safety.
6.Cost-Effective Premium Upgrade
Priced 15% lower than OEM upgraded components while offering equivalent or superior performance. Its long lifespan and reduced maintenance needs lower total cost of ownership for vehicle owners and fleet operators, making it a cost-efficient upgrade for Chery's advanced powertrain models.
