Title:
TARGET VEHICLE SPEED GENERATION METHOD AND TARGET VEHICLE SPEED GENERATION DEVICE FOR DRIVING ASSISTANCE VEHICLE
Document Type and Number:
WIPO Patent Application WO/2019/008648
Kind Code:
A1
Abstract:
In order to avoid discomfort to passengers whether or not there are obstacles present to the side of the vehicle travel path when traveling with driving assistance, this target vehicle speed generation device of a self-driving vehicle (driving assistance vehicle) is mounted with an automated driving control unit (2) (a controller) which generates a target speed of the vehicle depending on obstacles that hinder travel of the vehicle, wherein the automated driving control unit (2) is provided with a target travel path generation unit (21), a peripheral object information acquisition unit (22), and a target vehicle speed generation unit (23). The target travel path generation unit (21) generates a target travel path of the vehicle. The peripheral object information acquisition unit (22) acquires position information of obstacles on the vehicle travel path and position information of obstacles to the side, off of the vehicle travel path. The target vehicle speed generation unit (23) calculates the horizontal deviation from the vehicle travel path of obstacles on the vehicle travel path and the horizontal deviation from the vehicle travel path of obstacles off of the vehicle travel path, and generates a lower target vehicle speed for obstacles with a smaller horizontal deviation than for obstacles with a large horizontal deviation.
