1. Intelligent Adaptive Shifting Control
Control System Configuration: Vehicle-grade TCU (Transmission Control Unit) + dynamic shift logic algorithm
Scenario-Driven Optimization:
Normal Mode: Based on throttle opening and vehicle speed, achieves smooth shifting with a response time ≤ 0.3 seconds
Sport Mode: Delays upshifting and accelerates downshifting, enhancing dynamic acceleration performance by 20%
Economic Mode: Optimizes shift points to keep the engine running within the 1500-2500rpm high-efficiency range, improving fuel economy by 6%-9%
2. Integrated Safety & Fault Management
Safety Protection Mechanisms:
Overload Protection: Automatically limits torque output when the transmission temperature exceeds 120℃, preventing gear damage
Hill-Hold Function: Cooperates with the brake system to maintain the gear position for 2 seconds after the brake is released, avoiding rollback
Fault Diagnosis Capability:
Real-time monitoring of 22 key components (hydraulic valve body, speed sensor, clutch pack, etc.)
Supports identification of 24 fault codes, with a diagnostic accuracy of over 95% and an alarm response time < 200ms
1. Leading Technical Performance
Shifting Smoothness: Adopts a multi-plate wet clutch and electronic-hydraulic control, reducing shift shock by 45% compared to mechanical automatic transmissions
Structural Rigidity: The gearbox housing is made of high-strength aluminum alloy (processed with T6 heat treatment), with a torsional rigidity of up to 28,000 N・m/rad
Noise Control: Helical gear meshing + optimized oil pump design, achieving an operating noise of ≤ 62dB at 3000rpm (15% lower than the industry average)
2. Full-Lifecycle Cost Advantage
Procurement Cost: Relies on a domestic independent supply chain; the cost of core components is 30% lower than that of imported counterparts, with a single-unit price reduced by 1200-1800 RMB
Maintenance Cost: Adopts long-life transmission fluid (service interval up to 80,000km) and wear-resistant clutch friction plates, reducing annual maintenance costs by 40%
Repair Rate: Undergoes 200,000-cycle durability tests; the overall failure rate is ≤ 1.8% within 3 years (7 percentage points lower than the industry average)
