Abstract

The present invention provides a driving state recognition method, device, electronic equipment and turn signal control method. The driving state recognition method includes: determining the driver's head turning information based on the driver's face image; determining the vehicle based on the driving image based on the vehicle's operating parameters, determine the vehicle's corner amplitude information; based on the vehicle's position information, determine the vehicle-intersection relationship information; based on the turning head information, the lane information, the corner amplitude information and all According to the relationship information between the vehicle and the intersection, the driving state is determined, and the driving state includes turning, going straight and others. According to the driving state identification method of the present invention, comprehensive utilization of various valid information is realized by collecting the vehicle's own parameter information, the vehicle's external environment information and the driver's head movement, the driver's driving intention can be accurately recognized, and the driving intention can be determined. state, effectively making up for the driver's lack of vehicle control.

Description

technical field [0001] The present invention relates to the technical field of vehicle automatic control, and in particular, to a driving state identification method, device, electronic device and turn signal control method. Background technique [0002] With the development of the information age, there are more and more vehicle models using driver assistance systems, and the functions of the driver assistance systems are increasing, and the control accuracy is getting higher and higher. Identifying or predicting the driving state of the vehicle is the basis for the next step of auxiliary control. [0003] Take turning on the turn signal as an example: for example, the driver performs a lane change after turning on the turn signal. After the lane change is completed, due to the small angle of the steering wheel, the turn signal is always on; or the driver is ready to turn, and The turn signal was turned on in advance, and due to obstacle avoidance and other reasons, the st...
