Abstract:

A data-driven optimization method was investigated for automobile occupant restraint systems (ORS) based on composite deep Gaussian process regression network to improve the safety performance and to develop the efficiency of the ORS. In terms of the prediction of occupant dummy injury values, an improved composite deep Gaussian process regression network was proposed as the prediction model by combining neural network architecture with Gaussian process regression. Based on the prediction results, the ORS parameter optimization was carried out by using the group-based crow search algorithm. The method’s effectiveness was verified by using engineering simulation data. The results showed that this ORS design reduces the dummy injuries by up to 30.77% with an average of 12.11% compared to the original engineering scheme. Therefore, the method can predict the injury values for multiple parts of the dummy with a high-quality ORS design.
