The invention provides a vehicle damping control method and device, electronic equipment and a readable medium, which are applied to a continuous damping control system, and vehicle damping is associated with the control intensity of a vehicle body posture. The vehicle speed, the pitch angle speed, the roll angle speed and the unsprung acceleration of the vehicle in the running process are obtained; according to the unsprung acceleration and / or the vehicle speed, the driving road condition of the vehicle is determined; the driving pavement condition is used for indicating whether the driving pavement of the vehicle is a flat pavement and whether a vehicle impact object exists on the driving pavement; based on the pitch angle speed and / or the roll angle speed, the vehicle body posture state of the vehicle is determined; the vehicle body posture state is used for indicating whether the vehicle has vehicle body posture out-of-control risk; judging whether the vehicle meets a damping improvement condition or not based on the driving road condition, the vehicle speed and the vehicle body posture state; and if the vehicle meets the damping improvement condition, the control strength of the vehicle on the vehicle body posture is improved by improving the damping of the vehicle, and it is guaranteed that the comfort on the flat road surface is not deteriorated.

Provided is a program executed by a first computer comprising a processor and a memory. The program causes the processor to execute a step for generating a virtual space 501, a step for disposing a virtual camera and a user object 502 in the virtual space 501, a step for generating a virtual space image on the basis of the virtual camera, and a step for moving the user object 502 on the basis of a movement operation being performed. In the step for generating the virtual space image, when the movement operation is not being performed, the position of the virtual camera is controlled such that the virtual space image is an image of a first-person view of the user object 502, and when the movement operation is being performed, the position of the virtual camera is controlled such that the virtual space image is an image of a third-person view.

A virtual reality (VR) control method is provided. In the method, a VR system detects a shaking direction of a head-mounted device (2) of a VR user after receiving a displacement control instruction from the VR user, and then determines, according to an instruction matching rule (50), whether the displacement control instruction matches the shaking direction. If so, the VR system executes the displacement control instruction, and if not, the VR system does not execute the displacement control instruction. The virtual reality (VR) control method ensures that a head (1) of the VR user has reacted in advance to stimulate a vestibular system of an inner ear before a VR scene (4) changes, thereby avoiding motion sickness.

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.
