Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The high cost and frequent destruction of vehicle mocks during repeated collision tests for driver assistance systems make it economically unsustainable for extensive testing, as current methods do not allow for efficient and safe simulation of realistic collision scenarios.
Innovation Solution
A dummy vehicle with elastically deformable outer panels and a detachable opening element that disintegrates upon impact, allowing for pressure equalization and repeated use, simulating realistic collisions while minimizing damage and facilitating quick reassembly.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If a vehicle mock is used for repeated collision tests, then the testing of driver assistance systems can be performed frequently, but the vehicle mock is destroyed upon collisions causing high costs
Solution Approach 1:
The vehicle mock is divided into a self-supporting unit (first outer panel enclosing inner volume) and a separate opening element (second outer panel). This segmentation allows the opening element to detach upon impact, preventing destruction of the entire vehicle mock while enabling repeated testing.
Solution Approach 2:
The opening element is designed to be detachable and can be discarded or replaced after impact, while the main self-supporting unit remains intact and can be recovered for repeated use. This reduces the loss associated with each collision test.
2Strength
If the opening element is detachably connected to the first outer panel, then the self-supporting unit can disintegrate upon impact force to allow deformation, but the structural integrity during normal operation must be maintained
Solution Approach 1:
The connection between the opening element and first outer panel transitions from a stable, intact state during normal operation to a detached state upon impact. The detachable connection allows the structure to dynamically respond to impact forces by disintegrating the self-supporting unit, enabling deformation while maintaining integrity during normal use.
3Reliability
If the opening element is made detachable to allow pressure equalization, then the dummy vehicle can withstand impact forces, but the complexity of the connection mechanism increases
Solution Approach 1:
The opening element is extracted as a separate, detachable component from the main vehicle mock structure. This extraction allows the opening element to be removed or detached upon impact, enabling pressure equalization and reducing the complexity of making the entire structure detachable while maintaining reliability.

Implementation Method 1
a (e.g. elastically) deformable first outer panel (110), which at least partially encloses an inner volume (106) of the dummy vehicle (100)

AI summary
The present invention relates to a dummy vehicle for carrying out tests for a driver assistance system. The dummy vehicle has a deformable first outer panel, which at least partially encloses an inner volume of the dummy vehicle, and an opening element, which at least partially encloses the inner volume of the dummy vehicle, wherein the opening element and the first outer panel form a self-supporting unit. The opening element is detachably connected to the first outer panel such that, upon an influence of an impact force, the opening element is detachable from the first outer panel, such that the self-supporting unit is disintegratable and a deformation of the vehicle is providable.
