Problems solved by technology

[0004] In summary, the courtesy mode of unmanned vehicles at zebra crossings without signal lights needs to follow the original rules of interaction between drivers and pedestrians, and be more "anthropomorphic", but this technology is relatively lacking at present.

Embodiment Construction

[0033] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only some, not all, embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without making creative efforts belong to the protection scope of the present invention.

[0034] refer to figure 1 , is a schematic flow chart of a method for determining the mode of giving way to pedestrians at the zebra crossing of an unmanned vehicle according to the present invention. By selecting zebra crossings at intersections without signal lights, collect a large amount of real data on vehicle drivers yielding to pedestrians, and filter out data with obvious voluntary yield behavior and slight deceleration behavior; remove sudden braking d...

Abstract

The invention discloses a method for determining the mode of giving way to pedestrians on a zebra crossing of an unmanned vehicle: firstly, a zebra section controlled by no signal lights is selected, and data on real vehicle drivers giving way to pedestrians is collected; The data of the sudden braking behavior and being forced to stop by pedestrians, and the data of the driver's voluntary yielding and deceleration behaviors are retained; the retained data is then graded and combined, and based on the data after the graded combination, it is established that the driver is courteous to pedestrians. Finally, apply the established logic fuzzy rules when drivers give way to pedestrians in unmanned vehicles, and control unmanned vehicles to give way to pedestrians at zebra crossings without signal lights. This method can automatically realize the deceleration that is in line with the real driver's operation according to the current speed of the unmanned vehicle and the distance from the pedestrian, making the vehicle more stable and more anthropomorphic during driving.

Description

technical field [0001] The invention relates to the field of unmanned driving technology, in particular to a method for determining a mode of giving way to pedestrians in a zebra crossing of an unmanned vehicle. Background technique [0002] With the development of information technology, many large companies and universities have begun to independently develop unmanned vehicles. With the advancement of Google's self-driving technology and some accidents of Tesla's self-driving vehicles, safe driving of unmanned vehicles has become a social issue. a hotspot. [0003] There are subtle rules for the interaction between drivers and pedestrians at intersections without signal lights. Pedestrians have adapted to the driver's yield mode. Suspicion arises in the decision to cross the street, and the driver behind the unmanned vehicle will also have the idea of ​​​​overtaking due to not adapting to the yield mode of the unmanned vehicle in front, which will cause confusion in the t...
