Problems solved by technology

If the braking decision is made "one size fits all", for example, when the current speed of the vehicle is relatively fast and the car suddenly brakes at a yellow light, it is easy to cause rear-end collision, which will lead to poor traffic flow and even cause traffic accidents

Embodiment Construction

[0047] In the following, only some exemplary embodiments are briefly described. As those skilled in the art would realize, the described embodiments may be modified in various different ways, all without departing from the spirit or scope of the present invention. Accordingly, the drawings and descriptions are to be regarded as illustrative in nature and not restrictive.

[0048] figure 1 It is a flow chart of the yellow light decision-making method for unmanned vehicles provided by the embodiment of the present invention. Such as figure 1 As shown, the unmanned vehicle yellow light decision-making method of the embodiment of the present invention comprises:

[0049] Step S110, obtaining the signal light status at the intersection;

[0050] Step S120, if the status of the signal light is yellow, then judge whether the slow braking can stop the unmanned vehicle at the position before the stop line, and the acceleration of the slow braking is less than or equal to the preset...

Abstract

Embodiments of the present invention provide a yellow light decision-making method and device for an unmanned vehicle, and a computer-readable storage medium. Wherein the unmanned vehicle yellow light decision-making method comprises: obtaining the signal light state of intersection; If described signal light state is yellow light on, then judge whether slow braking can make unmanned vehicle stop running at the position before the stop line, described slow brake The acceleration is less than or equal to the preset acceleration threshold; if the slow braking can stop the unmanned vehicle at the position before the stop line, the decision of slow braking is given. The embodiment of the present invention makes a comprehensive analysis and judgment on the current road conditions and traffic conditions when the yellow light is on, provides a reasonable driving strategy for the yellow light, gives priority to slow braking, reduces the probability of accidents, and makes unmanned driving safer and smoother.

Description

technical field [0001] The present invention relates to the technical field of unmanned driving, in particular to a yellow light decision-making method and device for unmanned vehicles and a computer-readable storage medium. Background technique [0002] Yellow light is one of the signal lights that play an important role in traffic lights. Usually people's concept of yellow light is not as obvious as green light and red light. According to the provisions of China's traffic regulations, a yellow light means stop. The most popular explanation is to stop when the yellow light is on. The legal meaning of a yellow light is "warning". "Warning" means "warning", "alert" and "reminder". The unmanned vehicle system of the prior art usually gives the decision to brake when the yellow light is on. But in the actual driving scene, when the yellow light is on, a comprehensive analysis and judgment should be made on the road conditions and traffic flow conditions at that time. If th...
