To enable a road surface state to be appropriately determined even in a situation which cannot be dealt with by using only stored data learned in advance.SOLUTION: Environmental data is acquired by a peripheral device 22 provided on a vehicle, and on the basis of the environmental data, it is determined that a situation requires the learning of a support vector. Then, when the situation requires the learning of the support vector, road surface data including a feature quantity and raw wave form data is transmitted to a communication center 200 while being associated with the type of the situation, and the communication center 200 is caused to perform the learning operation of the support vector. Then, a learning result is transmitted from the communication center 200 to a vehicle side, and the support vector can be thereby updated according to the situation, in addition to support vectors stored as initial data in a support vector storage unit 21b.SELECTED DRAWING: Figure 2
【課題】事前学習した保存データのみでは対応できない状況においても、適切に路面状態の判別が行えるようにする。【解決手段】車両に備えられる周辺装置22にて環境データを取得し、この環境データに基づいてサポートベクタの学習を行うべき状況であることを判定する。そして、サポートベクタの学習を行うべき状況である場合には、状況の種類と紐付けして特徴量や生波形データを含む路面データを通信センター200に送り、通信センター200においてサポートベクタの学習演算を行わせる。この後、通信センター200から学習結果を車両側に伝えることで、サポートベクタ保存部21bに、初期データとして保存しているサポートベクタ以外にも、状況に合わせてサポートベクタを更新していくことができる。【選択図】図2
