Detailed Introduction

Automotive body electronic control system testing is a critical process to validate the functionality and reliability of vehicle electronic systems, covering comprehensive assessments of powertrain, chassis, safety, and comfort systems. Key test areas include: 1. Functional Verification: Using bench simulations or real-vehicle testing to validate the control logic and coordination of modules like Engine Control Units (ECUs), Anti-lock Braking Systems (ABS), and Electronic Stability Programs (ESP), ensuring precise execution of designed functions; 2. Performance Evaluation: Testing response time, control accuracy, and torque/load capacity, such as ABS effectiveness during emergency braking and ESP’s ability to correct vehicle skidding; 3. Environmental Adaptability Testing: Simulating extreme conditions like temperature ranges (-40°C to 180°C), humidity, vibration, and salt spray corrosion to assess system stability and durability in harsh environments; 4. Electromagnetic Compatibility (EMC) Testing: Conducting tests like Conducted Emission (CE), Radiated Emission (RE), and Electrostatic Discharge (ESD) to ensure systems are immune to external interference and do not disrupt other devices. Additionally, durability testing evaluates component lifespan under long-term alternating loads (e.g., rapid acceleration, bumpy roads), while diagnostic testing locates potential issues by reading Diagnostic Trouble Codes (DTCs). By integrating vehicle-level tests (e.g., CAN bus communication stability) with component-level validation, this process ensures the safety, reliability, and user experience of automotive electronic systems.
