TRAVEL CONTROL DEVICE AND TRAVEL CONTROL SYSTEM

摘要

Disclosed is a travel control device in which optimization of the traffic flow and minimization of energy consumption of vehicles are compatible with each other. The travel control device includes a target vehicle-speed calculation unit that includes a target vehicle-speed pattern adjustment processing unit generating a target vehicle-speed pattern based on a route passing speed pattern which is a passing vehicle-speed pattern within a certain distance generated in consideration of traffic congestion information, and an evaluation value calculation unit calculating an evaluation value based on a horizon length and the target vehicle-speed pattern, the horizon length representing the time taken until a vehicle arrives at an ultimate point generated in consideration of information on prospective traffic congestion which can occur in the future; and a target control volume computation unit that calculates control volume of controlling the vehicle based on the evaluation value.
