Description
technical field [0001] The invention is a multifunctional instrument for automobiles based on virtual technology and digital technology, and belongs to the category of multifunctional combined instruments for automobiles. Background technique [0002] The car instrument is the window for the driver to communicate with the car. The development of the car instrument has gone through four stages: the working principle of the first generation of car instrument is based on the mechanical principle, which is a mechanical instrument; the second generation of car instrument is based on the principle of electrical measurement. That is, through various sensors, the non-electrical physical quantity to be measured is converted into an electrical signal for measurement. It is an electrical instrument; the third generation is an analog circuit electronic instrument; the fourth generation is a stepping motor type full digital automotive instrument. Existing stepping motor-type full-digital...
