The invention discloses a static gesture intention recognition method and system based on dynamic feature assistance and a vehicle. The method comprises the following steps: step 1, hand detection; the method comprises the following steps of: 1, extracting dynamic features, 2, hand tracking, 3, static gesture classification, 4, spatial position judgment, 5, continuous frame recognition, 6, dynamic feature extraction and judgment, 7, static gesture judgment output and 8, in-vehicle application event response. According to the method, the static gesture actions are classified based on the hand action information of the user, the static gesture intention of the user can be recognized more accurately by combining the forward hand action trend characteristics in the static gesture control process, the misrecognition situation caused by the fact that similar gestures are static and free of operation or unconscious random waving is reduced, and the user experience is improved. And the false triggering rate is reduced, so that the cockpit gesture control function experience of the user is improved.
