VEHICLE SPEED LIMIT CONTROL DEVICE AND METHOD FOR CONTROLLING VEHICLE SPEED LIMIT

摘要

Provided is a vehicle speed limit control device comprised of a vehicle speed limit setting unit that sets and changes a vehicle speed limit in accordance with a vehicle speed limit instruction value that is changeable on the basis of the number of operations for a vehicle speed limit instruction means to satisfy a predetermined time requirement, a vehicle speed detection unit that detects an actual vehicle speed, and a driving power limiting unit that limits driving power of the vehicle in accordance with the vehicle speed limit and the actual vehicle speed, wherein the vehicle speed limit setting unit has a vehicle speed limit instruction step difference calculation unit that calculates a step difference between a vehicle speed limit instruction value immediately before the first operation of the vehicle speed limit instruction means and a vehicle speed limit instruction value at the present operation time of the vehicle speed limit instruction means, and a vehicle speed limit change ratio limiting unit that limits to make a change speed of the vehicle speed limit set in the vehicle speed limit setting unit more gradual as the step difference of the vehicle speed limit instruction value becomes smaller.
