Dongfeng GX EBS electronic control unit assembly 3632010-C6401

As the "command center" of the Dongfeng GX’s EBS, the 3632010-C6401 assembly delivers comprehensive, real-time control of the vehicle’s braking system, going beyond basic anti-lock functionality. It executes three critical core tasks: 1) Precision Brake Force Distribution (BFD): Adjusts pressure between front/rear wheels (and trailer/main vehicle for commercial models) based on load (detected via suspension sensors) and speed, preventing rear-wheel lock-up or front-end nose-diving; 2) Adaptive Anti-Lock Braking (ABS+): Modulates pressure for each wheel at a 1kHz sampling rate, maintaining steering control on slippery surfaces while shortening stopping distances by 15-20% compared to traditional ABS; 3) Brake Synchronization for Trailers: For Dongfeng GX tractor-trailer variants, it coordinates brake activation between the main vehicle and trailer (via CAN bus) to eliminate "trailer push" or "jackknifing" risks. Additionally, the ECU monitors brake system health in real time, triggering alerts for low fluid/air pressure or worn components—proactively preventing brake failures

The 3632010-C6401 EBS ECU is built with a automotive-grade rugged structure to withstand the extreme conditions of under-vehicle or engine bay mounting in Dongfeng GX vehicles. The outer housing uses die-cast aluminum alloy (ADC12) with a corrosion-resistant zinc-nickel plating, providing impact resistance (up to 25G peak acceleration, compliant with ISO 16750-3) to handle road debris and vibration during long-haul trips. The internal circuit board is coated with a high-temperature epoxy conformal layer, shielding components from moisture, dust, and chemical corrosion (e.g., road salt, brake fluid splashes). Critical hardware components—including a dual-core automotive MCU (e.g., NXP S32K39, 200+ MIPS processing power), power management ICs, and CAN bus transceivers—are rated for an operating temperature range of -40°C to 105°C, ensuring stable performance in freezing winters or hot desert conditions. The ECU also features an IP6K9K waterproof/dustproof rating, withstanding high-pressure water jets (e.g., vehicle washing) and temporary immersion—critical for durability in harsh weather

The 3632010-C6401 is engineered with Dongfeng GX-specific technical parameters to maximize EBS performance and reliability. Its processing capacity (200+ MIPS) enables simultaneous handling of 8+ sensor inputs and 12+ solenoid valve outputs, ensuring no latency in brake adjustments. The ECU supports a wide operating voltage range (9V-36V), compatible with the Dongfeng GX’s 12V (passenger) and 24V (commercial) electrical systems, and includes overvoltage/short-circuit protection to prevent damage from electrical surges (e.g., faulty alternators). For communication, it uses dual CAN bus channels (250 kbps for sensor data, 500 kbps for control signals) compliant with SAE J1939, ensuring fast, error-free data transmission between the ECU and EBS components. Additionally, it has a low standby power consumption (≤2.5W) to avoid battery drain, and its non-volatile memory can store up to 100 diagnostic trouble codes (DTCs) for 10+ years—simplifying long-term maintenance and fault tracing

Both the hardware and software of the 3632010-C6401 EBS ECU meet strict global automotive safety standards to ensure reliability in critical braking scenarios. The hardware is manufactured in accordance with ISO/TS 16949, with 100% factory testing including: electrical performance validation (signal accuracy, voltage stability), environmental stress testing (temperature cycling, humidity, vibration), and durability testing (simulating 15-year/300,000km lifespan). The software is certified to ISO 26262 (functional safety) at ASIL C level—higher than standard ABS ECUs—reflecting its role in controlling multiple safety-critical functions. It also complies with ECE R13-H (UN regulation for commercial vehicle braking) and Chinese national standards (GB 12676), ensuring global market compliance. To support customers, the ECU comes with a 24-month/50,000km warranty (covering hardware defects and software bugs) and dedicated technical support—including DTC interpretation, software calibration, and trailer EBS synchronization guidance for repair facilities
