Dongfeng KR truck parts Central control unit assembly 3600030-C5100

Built to unify and optimize vehicle control, this CCU assembly manages four core domains: powertrain coordination, body electronics, safety systems, and fleet diagnostics. It synchronizes engine torque output with transmission shift logic, reducing gear-shift shock by 30% and improving fuel efficiency by 4-6%. For body control, it regulates lighting (headlights, fog lights), climate control, and power windows with millisecond-level response. The safety module monitors ABS, airbags, and tire pressure, triggering alarms within 0.2s of anomalies. Additionally, it acts as a data hub for Dongfeng’s Intelligent Fleet Management System (IFMS), transmitting real-time vehicle status (fuel consumption, mileage, fault codes) to the cloud, enabling remote fleet monitoring

Engineered for the rigorous operating environments of commercial trucks, the CCU features military-grade hardware components. The main control chip is a NXP S32K39 MCU with a 1.2GHz dual-core processor, supporting 100,000+ instruction cycles per second for complex control algorithms. Internal circuits use automotive-grade capacitors (operating temperature -40℃ to 125℃) and gold-plated connectors (pull-out force ≥150N) to resist corrosion and vibration. The housing adopts a sealed, die-cast aluminum design with IP67 waterproof/dustproof rating, and a built-in heat sink that maintains chip temperature below 85℃ even in high-temperature engine compartments. It passes 500-hour continuous operation testing and 20g vibration testing (ISO 16750-3) without performance degradation

The CCU assembly integrates a self-diagnostic system and fault-tolerance mechanism to enhance operational reliability. It supports UDS (Unified Diagnostic Services) protocol, enabling technicians to read 200+ fault codes via Dongfeng’s dedicated diagnostic tool—pinpointing issues like sensor failures or communication errors within minutes. In case of a single sensor malfunction, the CCU automatically switches to redundant data sources (e.g., using GPS speed to compensate for a faulty wheel speed sensor) to maintain basic vehicle functions. It also records fault logs with time stamps, helping fleet managers analyze failure trends and implement preventive maintenance. This design reduces unplanned downtime by 45% compared to traditional control units

Optimized for fleet flexibility and easy maintenance, the CCU assembly features a modular design with expandable ports. It includes 8 reserved input/output (I/O) ports, supporting the addition of aftermarket devices like refrigeration unit controllers (for cold-chain trucks) or cargo monitoring sensors. The plug-and-play connector design allows a single technician to replace the unit in 30 minutes—no soldering or programming required, as it automatically synchronizes vehicle data with the ECU after installation. It also supports over-the-air (OTA) firmware updates via the IFMS, enabling remote activation of new features (e.g., eco-driving modes) without physical access. Backed by a 2-year/200,000km warranty, it ensures long-term reliability for diverse logistics scenarios
