Abstract

This invention discloses a steering wheel gesture recognition method, system, device, and storage medium. The method includes: acquiring basic capacitance value information and real-time capacitance value information of each sensing area of ​​the steering wheel in a first scenario, and steering wheel temperature information under various target environments; determining the force-bearing point position of the steering wheel based on the basic capacitance value information, steering wheel temperature information, and real-time capacitance value information; and generating a recognition result based on the force-bearing point position, wherein the recognition result includes at least the hand gesture posture of gripping the steering wheel. This invention solves the technical problem in related technologies where the influence of different temperature scenarios on the steering wheel capacitance value prevents the steering wheel from accurately recognizing the driver's grip posture.
