The invention discloses a driver wake-up-word-free interaction method, system and device and a storage medium, and the method comprises the steps: dividing a main driving sight range into a plurality of driver sight regions, presetting the region weight of each driver sight region, obtaining the sight direction coordinate and the head posture direction of a driver, and carrying out the wake-up-word-free interaction of the driver; performing weighted summation on the sight line direction coordinates and the head posture direction to obtain a current driver sight line area, performing weighted summation on an area weight of the current driver sight line area and an area weight of a driver sight line area around the current driver sight line area to obtain an interaction coefficient, and if the interaction coefficient is greater than an interaction threshold value, executing the step of executing the step of executing the step of executing the step of executing the step of executing the step of executing the step; if so, judging that the driver has an active interaction intention, entering a wake-up word-free interaction mode, and speaking a demand by the driver. The interaction intention of the driver is monitored in real time according to the sight direction coordinates and the head posture direction of the driver, and voice interaction without frequently inputting fixed wake-up words by the driver is achieved.
