摘要
智能网联汽车发展推动传感器向高精度、高可靠性方向升级,而在车辆行驶过程中,底盘承受的路面冲击、发动机振动等动态载荷,已成为传感器信号干扰的核心诱因。共振状态下惯性测量单元误差可激增至5°/s,直接影响电子控制单元ECU决策准确性。当前防护技术多聚焦单一振动场景,缺乏宽频带适配能力。本文探究信号失真的原因,并提出针对性防护方案,为提升车载传感器工作稳定性、保障行车安全提供技术支撑。
The development of intelligent connected vehicles is driving sensors toward higher precision and reliability.However,dynamic loads such as road impacts on the chassis and engine vibrations during vehicle operation have become the core causes of sensor signal interference.Under resonance conditions,the error of inertial measurement units can surge to 5°/s,directly affecting the accuracy of ECU decisions.Current protection technologies mostly focus on single vibration scenarios and lack broadband adaptability.This paper explores the causes of signal distortion and proposes targeted protection schemes,providing technical support for improving the operational stability of vehicle sensors and ensuring driving safety.
