This creation is about a virtual image display system for vehicles, especially a vehicle with the performance of virtual image display, which is applicable to various models and types of vehicles.

The public self-driving shuttle bus will provide passengers with more intelligent and innovative interactive services. In the future, the public self-driving shuttle bus will have a human-computer interaction system that integrates window conformal display technology and multiple forms to enhance MaaS (Mobility as a Service) service experience to construct self-driving ecology.

According to a study by the American Automobile Association (AAA), even if the self-driving car meets the standards in the safety test report, 73% of Americans still express fear of taking a fully autonomous vehicle, mainly because passengers cannot intuitively understand the driving situation in a self-driving environment. And it will always make passengers worry about the sense of security of "lack of assistance" in the self-driving environment. Even though the existing self-driving cars have set up monitors to provide some statistics, most passengers turn a blind eye and look at the road outside the window to confirm whether there are unmanned vehicles. Drive steadily.

In addition, many passengers in the self-driving environment hope to interact directly with the car through human voice, so the radio on the vehicle becomes very important, especially the noise generated by the environment on the vehicle will interfere, and the noise emitted by the passengers themselves If the sound is too low, or too far away from the radio to be transmitted clearly, it will make it impossible to interact in the self-driving environment.
