Ceres announces patent for motion sickness detection

Tianyancha’s intellectual property information shows that recently, Sails Motors Co., Ltd. applied for a patent titled “A Motion Sickness Recognition Method, Device, Storage Medium, and Equipment.” The abstract states that in this method, multiple source signal samples are used to train a teacher model to predict the motion sickness state of drivers and passengers. Through knowledge distillation technology, the soft labels provided by the trained teacher model and IMU signal samples are used to train a student model. The trained student model is designated as the motion sickness recognition model, which is then deployed on the vehicle’s onboard chip. By processing real-time collected vehicle IMU signals with this model, the motion sickness status of the vehicle’s occupants can be determined. This approach compresses the multi-source signal-based teacher model into a student model that only requires IMU signals as input, solving issues of limited signal collection and insufficient vehicle computing power in practical applications, enabling real-time and accurate recognition of motion sickness.
