AI Technical Summary

Technical Problem

Existing vehicle designs struggle to effectively suppress displacement vibrations caused by torsional deformation, which compromises driver comfort, particularly in battery electric vehicles where the weight distribution and rigidity balance are different from conventional engine-powered automobiles.

Method used

The vehicle's rigidity balance is adjusted by strategically distributing fastening points and components to align the torsional deformation node with the driver's seat, ensuring the driver's seat is positioned at the node of minimal deformation, and distributing loads efficiently through multiple fastening points to minimize displacement vibrations.

Benefits of technology

This configuration significantly reduces displacement vibrations felt by the driver, enhancing comfort by aligning the torsional deformation node with the seat, thereby improving the overall driving experience.

Abstract

We provide vehicles that can further improve driver comfort. [Solution] The rigidity balance of the vehicle front to rear is adjusted such that the nodal point An of the torsional deformation that occurs when the vehicle 10 is turned is located within the longitudinal range of the driver's seat 22. The vehicle 10 further has a battery 20 located under the floor of the vehicle 10, and a plurality of side fastening points 40a are provided at both ends of the battery 20 in the vehicle width direction for fastening the battery 20 to the frame of the vehicle 10, and the density of the side fastening points 40a behind the longitudinal center C of the battery 20 is higher than the density of the side fastening points 40a in front of the longitudinal center of the battery 20.
