Vehicle Unit Mounting Support System for Collision Energy Absorption
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing vehicle unit mounting systems lack the capability to effectively handle collisions while ensuring convenience in mounting units above the traveling unit, particularly in autonomous driving vehicles, as they do not provide adequate guidance on the necessity and selection of energy-absorbing units based on the purpose of the vehicle cabin.
Innovation Solution
A vehicle unit mounting support system that includes identification, determination, and display units to assess whether the vehicle cabin is for carrying people, and if so, necessitates the mounting of an energy-absorbing unit, selecting one with a higher deformation load based on the mass measured, and controlling vehicle speed and route to enhance collision protection.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the vehicle cabin forming unit is designed for carrying persons, then occupant safety is improved, but the device complexity increases due to the additional energy absorbing unit
Solution Approach 1:
The system performs preliminary determination of whether the vehicle cabin is for carrying persons before finalizing the mounting configuration. The determination unit assesses the cabin type in advance, and the display control unit prepares appropriate guidance information, allowing workers to make informed decisions about energy absorbing unit installation before actual mounting occurs.
Solution Approach 2:
The display control unit acts as an intermediary between the determination unit and the worker. It translates the determination results into user-friendly guidance information, mediating the complex technical assessment process and presenting it in an accessible format that helps workers understand whether the energy absorbing unit is necessary.
2Object-affected harmful factors
If the energy absorbing unit is mounted, then collision energy absorption is improved, but the weight of the vehicle increases
Solution Approach 1:
The energy absorbing unit is selectively installed only in specific locations and only when the vehicle cabin is determined to be for carrying persons. This localized application ensures that the weight increase from the energy absorbing unit occurs only when necessary for safety, rather than being a universal feature on all vehicles.
Solution Approach 2:
The system changes the configuration parameter of the vehicle by conditionally adding the energy absorbing unit based on the cabin type determination. When the cabin is identified as for carrying persons, the parameter changes from a basic mounting configuration to one that includes the energy absorbing unit, optimizing the balance between safety and weight.
3Reliability
If the vehicle speed is limited, then collision protection is improved, but the productivity of the vehicle decreases
Solution Approach 1:
The speed limit parameter is made dynamic rather than fixed. The system adjusts the speed limit based on whether the vehicle cabin is determined to be for carrying persons. When carrying persons, a lower speed limit is applied to enhance collision protection; when not carrying persons, the speed limit is relaxed to maintain productivity. This dynamic adjustment optimizes the balance between safety and operational efficiency.

AI summary
A CPU of a control device provided in a traveling unit causes a display to display information indicating that it is necessary to mount an energy absorbing unit capable of absorbing collision energy in a case where it is determined that a vehicle cabin forming unit is for the purpose of carrying a person, and causes the display to display information indicating that it is not necessary to mount the energy absorbing unit in a case where it is determined that the vehicle cabin forming unit is not for the purpose of carrying a person.
