図1は、実施の形態1にかかる表示制御装置の機能的構成の一例を示すブロック図である。実施の形態にかかる表示制御装置100は、第1取得部101と、第2取得部102と、表示制御部103とを含む。また、受付部104を備えてもよい。 (Embodiment 1)
FIG. 1 is a block diagram of an example of a functional configuration of the display control apparatus according to the first embodiment. The
第1取得部101は、移動体の目的地までの経路に関する情報を取得する。例えば、現在位置から目的地までの探索された経路を取得する。第2取得部102は、第1取得部101が取得した経路の周辺に存在し、移動体にエネルギーを補給するエネルギー補給施設(給電ステーション等)についての情報を取得する。
The first acquisition unit 101 acquires information related to the route to the destination of the moving object. For example, the searched route from the current position to the destination is acquired. The second acquisition unit 102 acquires information about an energy supply facility (such as a power supply station) that exists around the route acquired by the first acquisition unit 101 and supplies energy to the moving body.
表示制御部103は、エネルギー補給施設に関する情報を、複数設定された所定のエネルギー量で移動体が走行可能な範囲(例えば、満充電エネルギー量に対する10%毎)のそれぞれに存在する施設に区分して、表示部(不図示)に表示させる。
The display control unit 103 classifies the information related to the energy supply facilities into facilities that exist in each of the ranges in which the mobile body can travel with a predetermined amount of energy set (for example, every 10% of the fully charged energy amount). Display on a display unit (not shown).
例えば、表示制御部103は、エネルギー補給施設に関する情報を、移動体が第1のエネルギー量(例えば、満充電エネルギー量に対する10%)で走行可能な範囲に存在する第1のエネルギー補給施設に関する情報と、移動体が第2のエネルギー量(例えば、満充電エネルギー量に対する20%、30%、…100%など)で走行可能な範囲に存在し第1のエネルギー補給施設とは異なる第2のエネルギー補給施設に関する情報とを、識別可能な表示態様で表示部に表示させる。
For example, the display control unit 103 displays information related to the energy supply facility in relation to the first energy supply facility that exists in a range in which the mobile body can travel with the first energy amount (for example, 10% of the fully charged energy amount). And second energy different from the first energy supply facility that exists in a range in which the mobile body can travel with a second energy amount (for example, 20%, 30%,... Information related to the supply facility is displayed on the display unit in an identifiable display mode.
エネルギー量の表示は、消費エネルギー量とすれば、経路に沿って満充電エネルギー量に対する消費エネルギー量の例えば0%~100%まで10%毎に区切り、この範囲に含まれるエネルギー補給施設を表示する。100%は、例えば、満充電状態から走行して到達可能な地点である。また、バッテリ残量とすれば、経路に沿って例えば、満充電エネルギー量に対する残存エネルギー量の100%~0%まで表示させる。
If the amount of energy consumed is the amount of energy consumed, for example, it is divided every 10% from 0% to 100% of the amount of energy consumed relative to the fully charged energy amount along the route, and the energy supply facilities included in this range are displayed. . 100% is, for example, a point that can be reached by running from a fully charged state. In addition, when the remaining battery level is displayed, for example, 100% to 0% of the remaining energy amount with respect to the fully charged energy amount is displayed along the route.
経路に沿って表示とは、地図上の経路に沿って表示させてもよいが、例えば、表示画面の下部にエネルギー補給施設の表示領域を設けて、10%毎の各領域にそれぞれ存在するエネルギー補給施設を表示する。
“Display along the route” may be displayed along the route on the map. For example, a display area of the energy supply facility is provided at the lower part of the display screen, and the energy present in each of the 10% areas is displayed. Display supply facilities.
そして、この表示制御部103は、エネルギー補給施設までの距離と、移動体がエネルギー補給施設まで走行するのに必要なエネルギー消費量のいずれか、または双方を、エネルギー補給施設のそれぞれについて表示させる。
The display control unit 103 displays either or both of the distance to the energy supply facility and the energy consumption necessary for the mobile body to travel to the energy supply facility, or both of them.
受付部104は、表示制御部103が表示させているエネルギー補給施設のうちの少なくとも一つの選択を利用者から受け付けることができる。この選択により、第1取得部101は、選択されたエネルギー補給施設を経由する経路に関する情報を取得する。なお、無充電でも走行可能な場合で利用者が充電を選択しない場合もあり、この場合は無充電の最少消費や最短時間、最短距離のルート情報を表示することになる。
The accepting unit 104 can accept the selection of at least one of the energy supply facilities displayed by the display control unit 103 from the user. By this selection, the first acquisition unit 101 acquires information related to a route that passes through the selected energy supply facility. In some cases, the vehicle can be driven without charging, and the user may not select charging. In this case, the minimum consumption of the non-charging, the shortest time, and the shortest distance route information are displayed.
第1取得部101が取得する、経路の探索手法について説明する。一般的な経路探索は、リンクおよびノードで表現されるネットワーク上の、最短経路探索アルゴリズムによって実現される。利用者が目的地を設定すると、最短経路探索アルゴリズムにより、出発地から目的地までの合計コストが最小となる経路を探索する。一般的な最短経路探索アルゴリズムとしては、A*(エースター)探索アルゴリズム、ダイクストラ法、ワーシャル・フロイド法等がある。
A route search method acquired by the first acquisition unit 101 will be described. A general route search is realized by a shortest route search algorithm on a network expressed by links and nodes. When the user sets a destination, a route that minimizes the total cost from the departure point to the destination is searched by the shortest route search algorithm. Common shortest path search algorithms include the A * (Aster) search algorithm, the Dijkstra method, the Warsal Floyd method, and the like.
経路探索部では、経路探索の条件(目的地、所要時間や所要距離等)、現在位置、車速、渋滞等の情報に基づき、探索を行う。この経路探索部は、記憶部等に格納されている道路データを読み出し、第一のノード(例えば現在位置)から第二のノード(例えば目的地)までの推奨経路をコストに基づいて決定する。
The route search unit searches based on information on route search conditions (destination, required time, required distance, etc.), current position, vehicle speed, and traffic jam. The route search unit reads road data stored in a storage unit or the like, and determines a recommended route from the first node (for example, current position) to the second node (for example, destination) based on the cost.
そして、経路探索部は、第一のノードから第二のノードまでの経路における累計コストである第一コスト(Σcost1)と、経路のうち、エネルギー補給施設ノードIDが関連付けられていないノード間のコストの累計コストである第二コスト(Σcost2)と、に基づいて、推奨経路を決定する。推奨経路は、例えば、第一コストと第二コストのそれぞれに対し所定の重み付けを行い、重み付けされた第一コストと第二コストとの和が最小となる経路を推奨経路として決定する。例えば、現在位置から目的地まで最短時間や最短距離の経路をそれぞれ推奨経路として求める。
Then, the route search unit includes the first cost (Σcost1) that is the accumulated cost in the route from the first node to the second node, and the cost between the nodes that are not associated with the energy supply facility node ID in the route. The recommended route is determined on the basis of the second cost (Σcost2) that is the accumulated cost. For the recommended route, for example, predetermined weighting is performed on each of the first cost and the second cost, and the route that minimizes the sum of the weighted first cost and second cost is determined as the recommended route. For example, the route with the shortest time and the shortest distance from the current position to the destination is obtained as the recommended route.
記憶部には、ノードデータと、ノード間を連結するリンクデータと、リンク毎に設定されたコストデータとからなる道路リンクデータテーブルが記憶されている。そして、エネルギー補給施設の情報の取得により、各ノードには、最寄りのエネルギー補給施設(充電スポット)が位置するノードを示すエネルギー補給施設ノードの識別子(ノードID)が関連付けて記憶される。
The storage unit stores a road link data table including node data, link data for connecting nodes, and cost data set for each link. As a result of acquiring information on the energy supply facility, an identifier (node ID) of the energy supply facility node indicating the node where the nearest energy supply facility (charging spot) is located is stored in association with each node.
これら経路探索部および記憶部は、表示制御装置100が設けられる移動体に設けてもよいし、移動体の外部、例えば、サーバに設けられ、移動体との間の通信により表示制御装置100が取得する構成としてもよい。
The route search unit and the storage unit may be provided in a moving body in which the display control device 100 is provided, or provided outside the moving body, for example, in a server, and the display control device 100 is provided by communication with the moving body. It is good also as a structure to acquire.
図2は、実施の形態1にかかる表示制御装置の処理手順の一例を示すフローチャートである。表示制御装置100は、第1取得部101により、移動体の目的地までの経路を取得する(ステップS201)。また、第2取得部102により、経路の周辺に存在するエネルギー補給施設の情報を取得する(ステップS202)。そして、表示制御部103により、エネルギー補給施設の情報を、所定のエネルギーの範囲毎に区分して表示する(ステップS203)。
FIG. 2 is a flowchart of an example of a processing procedure of the display control apparatus according to the first embodiment. The display control apparatus 100 uses the first acquisition unit 101 to acquire a route to the destination of the moving object (step S201). In addition, the second acquisition unit 102 acquires information on energy supply facilities existing around the route (step S202). Then, the display control unit 103 displays the information on the energy supply facility by dividing it into predetermined energy ranges (step S203).
上記実施の形態によれば、移動体が目的地まで移動する際の経路上に、エネルギー量毎にエネルギー補給施設の情報を表示させることができる。例えば、満充電エネルギー量に対する消費エネルギー量の0~10%のエネルギー量で移動可能な経路範囲にあるエネルギー補給施設を表示する。同様に、異なるエネルギー量、例えば、10%~20%のエネルギー量で移動可能な経路範囲にある他のエネルギー補給施設を表示する。
According to the above embodiment, the information of the energy supply facility can be displayed for each energy amount on the route when the moving body moves to the destination. For example, an energy supply facility in a movable route range with an energy amount of 0 to 10% of the consumed energy amount with respect to the fully charged energy amount is displayed. Similarly, other energy supply facilities in the path range that can be moved with different energy amounts, for example, energy amounts of 10% to 20%, are displayed.
これにより、利用者は目的地までの経路上において、エネルギー量(距離)毎に存在する複数のエネルギー補給施設を把握できるようになる。これにより、利用者は、どの程度エネルギー量を消費した状態となったときにどのエネルギー補給施設によりエネルギーを補給できるかを容易に知ることができるようになる。そして、利用者毎にエネルギー補給のタイミングが異なっても、各利用者に対して適切なエネルギー補給施設を表示案内できるようになる。
This allows the user to grasp a plurality of energy supply facilities that exist for each energy amount (distance) on the route to the destination. Thus, the user can easily know how much energy is consumed by which energy supply facility when energy is consumed. And even if the timing of energy replenishment differs for each user, an appropriate energy replenishment facility can be displayed and guided to each user.
