Description

Technical Field

[0001] The present invention relates to the technical field of automobile electronics, and in particular to an intelligent cockpit for preventing motion sickness for rear passengers. Background Art

[0002] At present, when the vehicle is driving, the rear passengers lack sufficient field of vision and are dealing with a visually closed motion environment. When their eyes are fixed on objects inside the vehicle, what the passengers see are stationary objects in the car. The vision tells the person that the person is stationary at this time, and the brain receives a "no movement" signal. However, the organs responsible for regulating balance, such as the inner ear, produce corresponding reactions due to the person's movement and transmit them to the brain, resulting in inconsistency between the two types of information received by the brain. Therefore, the brain reacts accordingly and induces vomiting, thereby producing motion sickness symptoms. Currently, precise control cannot be achieved through self-adjustment by the passengers, resulting in poor anti-motion sickness effect and affecting user experience.

[0003] The prior art CN118528908A provides an anti-motion sickness implementation method, device, electronic device and vehicle. When it is detected that the vehicle starts the motion sickness mode, the first displacement of the vehicle in the current time period, the second displacement of the passenger in the current time period and the third displacement of the vehicle in the target time period are obtained, and the vehicle's light-emitting panel is controlled to open; the target light-emitting area of ​​the light-emitting panel is determined by a preset algorithm and the first displacement, the target flashing frequency of the light-emitting panel is determined by the preset algorithm and the second displacement, and the target color and target brightness of the light-emitting panel are determined by the preset algorithm and the first displacement / third displacement; the target light-emitting area, target flashing frequency, target color and target brightness of the light-emitting panel are set to simulate visual balance linkage, and the light-emitting area, flashing frequency, color and target brightness of the light-emitting panel are controlled to achieve the desired effect. Brightness is used for visual compensation, creating a relatively balanced visual experience of "light follows the movement of the car" and improving the motion sickness of the rear passengers. In the embodiment of the present invention, the luminous area, brightness, color, and frequency change of the vehicle's luminous panel are adjusted in real time based on the collected multiple information, creating a relatively balanced visual experience of "light follows the movement of the car" and improving the motion sickness of the passengers. In addition, in the embodiment of the present invention, the passenger's sense of balance can be judged by collecting data from multiple parties and conducting joint analysis, so that the judgment result is more accurate. Customized development of light effects can be provided to support car owners to control the light-emitting position of the light-emitting panel in different ways, and combined with biometric technology, different light effect modes can be automatically adjusted by identifying the identity and emotions of the passengers, thereby enriching user choices and enhancing user experience.

[0004] However, in the prior art, the light-guiding method is used to prevent motion sickness in the vehicle passengers, which has poor applicability and results in poor anti-motion sickness effect. Summary of the invention
