更新停靠站狀態

本文假設您已詳讀以下文章：

建立出貨工作
排定工作簡介，詳細說明工作、停靠點和車輛之間的關係。

如「Fleet Engine 基礎知識」的「排定工作」一節所述，您可以建立工作並將其與車輛停靠點建立關聯，藉此模擬真實世界中工作與車輛預計停靠位置之間的關係，方便司機完成工作。

接著，只要將最新狀態傳送至 Fleet Engine，系統就能在工作的整個生命週期中，完善執行路線規劃和狀態更新，方便您妥善管理工作進度。很重要的一點是，在車輛接近、抵達和離開停靠點時更新停靠點。如此一來，無論是車隊營運人員或客戶，都能取得工作進度的相關報表和分析資料。這些狀態項目如下：

En route：VehicleStop 的 STATE 列舉值為 ENROUTE，代表停靠點是車輛行程表中的下一站。就工作而言，這表示與停靠點相關聯的工作，將是清單中下一個要完成的工作。
Arrived：VehicleStop 的 STATE 列舉值為 ARRIVED，代表車輛已抵達停靠點。就工作而言，這表示目前正在處理與停靠點相關聯的工作。
Completed：從車輛的停靠點清單中移除停靠點，即可將停靠點標示為已完成。這麼做時，Fleet Engine 會自動將所有相關聯的工作標示為「CLOSED」。如要進一步瞭解如何結束工作，請參閱「完成工作」。

本文說明如何使用伺服器端方法更新停靠點狀態。如果允許司機使用信任的裝置管理工作，您也可以透過司機應用程式執行這項操作。兩種方法請擇一使用，以維持單一資料來源，並避免發生競爭狀況。

車輛正在前往停靠點

當車輛開始導航前往下一個停靠點時，系統應通知 Fleet Engine。這有助於提升預計抵達時間和路線計算的準確度。

停靠點狀態更新的必填欄位

Fleet Engine 會忽略實體中用於通知的其他所有欄位。

欄位	值
`remainingVehicleJourneySegments`	剩餘車輛停靠點清單，狀態標示為 State.NEW。

Enroute to stop example

下列範例說明如何使用 Java gRPC 程式庫或對 UpdateDeliveryVehicle 發出 HTTP REST 呼叫，通知 Fleet Engine 車輛正前往下一個停靠點。所有其他停靠點都會標示為新停靠點。
