As a key technology in the intelligent transformation of the automotive industry

intelligent sensing technology plays an important role in the precise control

performance optimization and safety improvement of automotive parts. This paper systematically describes the definition

classification system and technology evolution path of intelligent sensing technology

and focuses on analyzing its application in the fields of powertrain optimization

safety system upgrade and body control system. At the same time

it prospectively discusses the advanced development trends such as the fusion of smart materials and sensing and the extended application of digital twin

which provides theoretical reference and practical guidance for the further application of intelligent sensing technology in automotive parts.
