Vehicle Front Structure for Protecting Autonomous Driving Units
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing vehicle front portion structures fail to effectively protect autonomous driving units during impacts without compromising user space.
Innovation Solution
A vehicle front portion structure that includes a dash panel separating the power unit compartment from the cabin, a partition wall extending upward to divide the cabin, a front vehicle seat supported by a seat support member, and the autonomous driving unit positioned within the area bounded by these components, with additional support from brackets and dash panel reinforcement to enhance protection during frontal impacts.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Area of stationary object
If the autonomous driving unit is mounted between the rear seat and the floor panel, then user space is preserved, but protection ability during impact is insufficient
Solution Approach 1:
The autonomous driving unit is relocated from the traditional rear seat area to the front portion of the cabin, specifically in the area surrounded by the dash panel, partition wall, and seat support member. This spatial repositioning in a different dimension of the cabin allows the unit to be protected by the front structure while preserving user space in the rear area.
Solution Approach 2:
The cabin is divided into front and rear portions by a partition wall that extends from the dash panel to the roof panel. This segmentation creates a dedicated front area for the autonomous driving unit, separated from the rear passenger space, thereby providing structural protection while maintaining user space in the rear portion.
2Reliability
If the autonomous driving unit is positioned in the front portion of the cabin surrounded by dash panel, partition wall, and seat support member, then protection ability during impact is improved, but user space may be reduced
Solution Approach 1:
The partition wall is designed with different heights in different areas, extending from the dash panel to the roof panel in the front portion while allowing the rear portion to maintain full height. This local variation in structure provides enhanced protection for the autonomous driving unit in the front area while preserving maximum user space in the rear passenger area.
Solution Approach 2:
The autonomous driving unit is positioned in the vertical space between the dash panel and the partition wall, utilizing the three-dimensional space efficiently. This placement protects the unit through the front structural elements while not encroaching on the horizontal user space in the rear cabin area.

AI summary
A vehicle front portion structure includes: a dash panel separating a power unit compartment provided at a lower portion of a vehicle front portion from a cabin; a partition wall having a lower end portion secured to a vehicle rear end portion of the dash panel and extending in a vehicle upward direction to divide the cabin into a front portion and a rear portion; a front portion vehicle seat disposed on the dash panel; a seat support member supporting the front portion vehicle seat from a vehicle lower side and having a front end portion secured to the dash panel and a rear end portion secured to the partition wall; and an autonomous driving unit, at least part of the autonomous driving unit being disposed in an area surrounded by the dash panel, the partition wall, and the seat support member.
