1results about How to "Prevent motion sickness" patented technology

The application discloses a trajectory tracking multi-algorithm fusion control method considering riding comfort. A vehicle yaw single-track dynamics model is established; based on an LSTM neural network model, vehicle motion state parameters are taken as model input information, and prevention of passenger motion sickness is taken as a target to train an expected anti-sickness yaw angle; a MPC model predictive control method is used, the vehicle yaw single-track dynamics model is taken as a basis, a prediction model of the MPC is established based on a state vector, a control variable and an output variable, a predicted path and a predicted yaw angle are output, a cost function and a constraint are designed based on a deviation of the expected path and the predicted path, a deviation of the expected anti-sickness yaw angle and the predicted yaw angle, and an expected front wheel rotation angle is solved; a PSO particle swarm optimization algorithm is used to obtain optimal key control parameters of the MPC, the MPC is updated, and then an updated expected front wheel rotation angle is obtained. The application effectively guarantees safe and smooth driving of the vehicle, and comprehensively improves expected path tracking accuracy and a passenger motion sickness discomfort state.
