Background The LC dimming glass is a core component for realizing privacy protection and intelligent light adjustment in a vehicle-mounted scene, can flexibly realize the switching of glass between transparent and opaque states by controlling the on-off of current to change the arrangement state of liquid crystal molecules, and is widely applied to the light adjustment of vehicle windows at present. In the prior art, as in Chinese patent, the invention is named as a dimming glass controller, a dimming glass control system and a control method, while the patent number is CN105022182B, basic control logic of vehicle-mounted LC dimming glass is disclosed, the control scheme still has a plurality of defects in practical application, and the privacy, safety and intelligent experience of use are difficult to consider, and the specific problems are as follows: The light-dimming memory strategy is unreasonable in design, the light-transmitting state memory function is not set in part of the scheme, the light-dimming parameters are manually adjusted by a user after the vehicle is powered on each time, the operation is complex, the intelligent experience is greatly reduced, the light-transmitting state is directly restored when the vehicle is in last dormancy after the vehicle is started although the memory function is set in part of the scheme, if no passenger exists in the corresponding seat area, the privacy of the environment and articles in the vehicle is easily leaked due to the transparent state of the glass, and the outstanding contradiction between privacy protection and intelligent experience is formed. The linkage regulation and control mechanism of the dynamic state of the passenger is lacking, when the passenger temporarily leaves a seat area in the running process of the vehicle, the existing control scheme cannot sense the state change in real time, the dimming glass still keeps the original light-transmitting state, the articles in the vehicle are easy to be exposed, and the privacy security hole for midway leaving the vehicle exists. And when the vehicle is in a non-dormant state and no passengers are in the vehicle, if the dimming glass is in a transparent state, the direct sunlight can cause rapid temperature rise in the vehicle, so that the aging of the vehicle interior is easily accelerated, the vehicle-mounted electronic equipment is damaged, inflammable substances in the vehicle can be possibly induced to spontaneously ignite, and obvious potential safety hazards exist. In addition, the capacitive resistance type occupancy sensor is a detection component commonly used in the prior art of a vehicle and is mainly applied to a safety belt reminding function, the output resistance value can be changed by closing a pressure trigger switch, accurate and real-time detection of the sitting state of a passenger is achieved, the detection characteristic of the sensor is highly matched with the control requirement of vehicle-mounted LC dimming glass, the function of the sensor is not expanded to be applied to the control field of the vehicle-mounted LC dimming glass at present, the idling of the prior hardware resources of the vehicle is caused, and technical support is not provided for intelligent control of the dimming glass.
