The invention discloses a virtual key system of a car steering wheel and a car. The system comprises the steering wheel provided with a projection window, an internal line laser arranged in the center of the steering wheel and used for forming an infrared plane on the surface of the steering wheel through the projection window, a projection module comprising laser and a holographic lens, a virtual key fixing apparatus used for projecting virtual keys in the fixed positions of the steering wheel, a camera arranged above the steering wheel and used for capturing first light spot information when laser emitted by the line laser is reflected, and a processor connected with the camera and used for receiving the first light spot information captured by the camera and calculating position information of the corresponding virtual keys according to the first light spot information to enable the car to perform corresponding function control according to the position information of the corresponding virtual keys, wherein the laser forms the virtual keys through the holographic lens. According to the system, the design of the steering wheel is simpler and the car design and production are facilitated.
Description
technical field [0001] The invention relates to the technical field of automobiles, in particular to a virtual button system for a steering wheel of an automobile and an automobile with the virtual button system. Background technique [0002] With the rapid development of the automotive technology field and the improvement of people's driving experience requirements, more and more electronic devices are applied to the car. For example, the driver wants to be able to drive the vehicle while listening to music. Existing cars generally meet the driver's needs by installing multimedia equipment, such as installing physical buttons on the steering wheel of the car, connecting the circuit after the physical buttons, and passing the physical buttons. Press to control the multimedia device to play music, etc. [0003] However, with the increase of automotive electronic equipment, there are more and more control buttons, and there are more and more control buttons installed on the s...
