Method for determining zebra crossing pedestrian giving-way mode of driverless automobile

Abstract

The invention discloses a method for determining a zebra crossing pedestrian giving-way mode of a driverless automobile. The method comprises the following steps: firstly, selecting a zebra crossing road section without signal lamp control, and collecting pedestrian giving-way data of a real vehicle driver; then screening the collected data, removing emergency brake behaviors adopted by a driver and data that the driver is forced to stop by pedestrians, and retaining the data of active giving-way and deceleration behaviors of the driver; grading and combining the retained data, and establishing a logic fuzzy rule when a driver gives way to pedestrians according to the graded and combined data; and finally, applying the established logic fuzzy rule of the driver in giving way to the pedestrian to the unmanned vehicle, and controlling the unmanned vehicle to give way to the pedestrian at the zebra crossing without signal lamp control. According to the method, the deceleration meeting theoperation of a real driver can be automatically obtained according to the current speed of the driverless automobile and the distance from the driverless automobile to the pedestrian, so that the automobile is more stable and personified in the driving process.

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...

AI Technical Summary

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.
