Travel control device and travel control system |
摘要 |
A 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. The travel control device also includes 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. |

1. A travel control device comprising:
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. |
