【Abstract】The development of intelligent connected vehicles is driving sensors toward higher precision and reliability.However，dynamic loads such as road impacts onthechassis and engine vibrations during vehicle operation have becomethecorecauses ofsensorsignal interference.Underresonanceconditions，the erorof inertial measurement units can surge to 5% ，directly affecting the accuracy of ECU decisions. Current protection technologies mostly focus on single vibration scenariosand lack broadband adaptability.This paper explores the causesof signal distortion and propose targeted protectionschemes，providing technical supportfor improving theoperationalstabilityof vehicle sensors and ensuring driving safety.
