The invention discloses a car-mounted multimedia gesture control method based on electrostatic detection, provides a method for achieving gesture recognition by detecting electrostatic disturbing signals generated during hand movement, and belongs to the field of electrostatic detection. The method comprises the following steps that twenty ways of electrostatic detection arrays capable of detecting the human body hand movement electrostatic disturbing signals are laid; the electrostatic disturbing signals generated when the hand moves in front of the electrostatic detection arrays in a car-mounted environment are acquired; the acquired voltage signals are compared with a preset threshold value; amplitude matrixes V and zero crossing moment matrixes T of twenty ways of electrode plate are recorded; lattice areas where the hand passes are judged, and the movement tendency of the hand is described; and the signals are processed and sent to a car-mounted system, and control over the car-mounted multimedia system through hand static electricity is achieved. According to the method, potential safety hazards caused by the fact that the attention of a driver is influenced by operations of looking up keys and the like in the driving process can be reduced, and the complexity, logic design difficulty and power consumption of a gesture recognition system are reduced.
