Detailed Introduction

Automotive sensor testing is a critical process to validate sensor performance and reliability, ensuring accurate monitoring of vehicle status and reliable signal output. Key tests include: 1. Functional Verification: Simulating operating conditions (engine speed, tire pressure, temperature changes) to check if sensor signals match design logic (e.g., linearity of throttle position sensors, voltage response of oxygen sensors); 2. Performance Testing: Evaluating measurement accuracy (error range), response time (dynamic characteristics), and interference resistance (signal stability under vibration or electromagnetic environments); 3. Environmental Adaptability Testing: Simulating extreme temperatures (-40℃~125℃), humidity (95%RH), vibration (various frequencies/amps), and salt spray corrosion to verify sensor durability in harsh conditions; 4. Electromagnetic Compatibility (EMC) Testing: Conducting tests for conducted/radiated immunity and electrostatic discharge (ESD) to ensure sensors are immune to vehicle electromagnetic interference and do not emit harmful radiation. Additionally, durability testing subjects mechanical components (e.g., pressure sensor diaphragms) to millions of load cycles to assess fatigue life, while fault injection tests simulate sensor failures (signal interruption, drift) to evaluate vehicle system fault tolerance. This testing is crucial for ensuring the stable operation of engine control, safety systems (ABS/ESP), and comfort functions (air conditioning, seat adjustment).
