The invention discloses a vehicle driving state detection method. The method comprises the steps: obtaining a monitoring video stream, carrying out vehicle detection on the monitoring video stream, and obtaining a target detection frame of a current vehicle in a plurality of monitoring images in the monitoring video stream; determining a vehicle movement track vector according to the target detection frame positions of the Nth frame of monitoring image and the Mth frame of monitoring image in the monitoring video stream, wherein N is smaller than M, and the difference between M and N is largerthan a preset value; calculating a vector included angle between the vehicle movement track vector and a preset traffic flow direction vector; and if the vector included angle is greater than a preset included angle, judging that the current driving state of the vehicle is reverse driving. According to the invention, the detection accuracy of the vehicle driving state can be improved. The invention further discloses a vehicle driving state detection device, electronic equipment and a storage medium, which have the above beneficial effects.
