Abstract

The invention relates to a driving direction safety early warning method and device and a driving controller. The driving direction safety early warning method comprises the steps: acquiring the visual information in the driving direction of a vehicle; acquiring distance information of an obstacle closest to the vehicle in the driving direction; obtaining category information of the obstacle according to the visual information, wherein the category information is used for determining whether the obstacle is a dangerous obstacle or not; and if it is determined that the driving collision dangerexists according to the category information, the distance information and the current driving speed, executing an early warning action. According to the technical scheme, the distance and the category of the obstacle are determined, on the premise that the obstacle is dangerous, early warning is conducted only when the obstacle has the collision danger, such that the early warning accuracy is greatly improved, false detection caused by safe obstacles such as small grass can be eliminated, and therefore the driving experience is further improved.

Description

technical field [0001] The invention relates to the technical field of automobile safety, in particular to a safety early warning method and device for driving direction, and a driving controller. Background technique [0002] At present, in order to improve driving safety, in order to ensure the safety when moving forward or reversing, many cars have been equipped with reversing radar systems, and there are more and more models equipped with front-view cameras and rear-view cameras. During driving, the reversing radar system detects the distance of obstacles, and gives an alarm when the obstacle distance is less than the safe value. When the alarm is issued, the user can observe the obstacles in the driving direction through the camera and perform the next driving operation. [0003] In the process of implementation, the inventor found that the traditional technology has at least the following disadvantages: the realization of traffic warning based on the reversing radar, b...
