Abstract: The front pedal in the cockpit belongs to the automotive interior system, and is the stepping platform for passengers to get on and off the automobile. This article introduces the design requirements of the front pedal in terms of manufacturing process, materials, surface antislip structure, human-machine layout requirements, and appearance, as well as the experimental verification of the rationality of the design that needs to be met during the trial production process of the front pedal, such as meeting the requirements for protrusions inside passenger automobile, combustion characteristics of automotive interior materials, and prohibited substances. Finally, finite element analysis software HyperMesh and ABAQUS are used to analyze the stiffness of the front pedal and calculate its deformation under an external force of 500 N. The results show that the deformation of the front pedal under the vertical load of 500 N is 0.36 mm, which meets the requirement of the company standard that the deformation should not exceed 0.5 mm, it can provide corresponding reference for the design and development of the front pedal of subsequent vehicle models.
