Generative AI and surrogate model for front-design changes that meet pedestrian-protection performance

Honda estimates its generative AI design tool cuts design development time by more than 40%

WorkingCompany's own claim

Problem

Front designs had to meet pedestrian-protection performance, and checking each design with CAE analysis could take about a day. Design changes went back and forth between designers and analysts.

Approach

Honda developed the system in March 2025 and applied it to actual vehicle development. A designer submits a 3D design and gets performance checks and revised proposals in a chat, using a large language model from OpenAI. A surrogate model stands in for CAE to judge performance almost instantly. Morphing, an image-processing technique, generates the revised shapes, because direct AI generation could not reach millimeter precision. Designers can set limits such as keeping the hood height.

Results

40%以上estimated reduction in design development time (Honda's estimate, not a measured result); currently covers pedestrian-protection performance onlyCompany's own claim[1]
90%程度accuracy of the surrogate model compared with conventional CAE, so a final CAE check is still neededCompany's own claim[1]

Takeaway

The surrogate model reached about 90% of CAE accuracy, so Honda still ran a final CAE check. The time saving is Honda's estimate, not a measured result.

The article, from the print edition of 2025-12-22, described Honda's chat-based generative AI system for front designs. It was developed in March 2025 and applied to vehicle development. It reported an estimated cut of more than 40% in design development time and surrogate-model accuracy of about 90% against CAE.
