打造隨選行程的交通工具

如要在車隊引擎中建立隨選行程的車輛,請使用 CreateVehicle 端點搭配 CreateVehicleRequest。這個端點需要具備 Fleet Engine On-demand Admin 角色的帳戶。

隨選行程車輛的欄位

建立隨選行程的車輛時,您必須設定必填欄位。您也應該熟悉某些車輛欄位如何影響 Fleet Engine 中的其他功能。如要更新車輛欄位,請參閱這篇文章

預約行程的必填欄位

  • vehicle_state:預設為不明,但應設為線上或離線。如要瞭解如何設定車輛狀態欄位,請參閱「更新車輛欄位」一文。
  • supported_trip_types:預設為不明,但應設為「共用」或「專屬」,或兩者皆設為。詳情請參閱隨選行程指南中的「行程類型」。
  • maximum_capacity:車輛可載運的乘客人數,不含駕駛人 (依定義)。
  • vehicle_type:值為 AUTOTAXITRUCKTWO_WHEELERBICYCLEPEDESTRIAN。可用於篩選車輛搜尋結果。這也會影響預估到達時間和路線計算。Fleet Engine 會根據下列車輛類型群組,提供與行駛模式相對應的路線和行程計算結果:
    • AUTOTAXITRUCK:例如高速公路。
    • TWO_WHEELER:例如不會傳回不允許 2 輪車的路線。
    • BICYCLE:例如單車道。
    • PEDESTRIAN:例如僅供行人使用的橋樑和人行道。

其他欄位

車輛建立範例

CreateVehicle 傳回的值是已建立的 Vehicle 實體。

Java

static final String PROJECT_ID = "project-id";

VehicleServiceBlockingStub vehicleService =
    VehicleService.newBlockingStub(channel);

String parent = "providers/" + PROJECT_ID;
Vehicle vehicle = Vehicle.newBuilder()
    .setVehicleState(VehicleState.OFFLINE)  // Initial state
    .addSupportedTripTypes(TripType.EXCLUSIVE)
    .setMaximumCapacity(4)
    .setVehicleType(VehicleType.newBuilder().setCategory(VehicleType.Category.AUTO))
    .addAttributes(VehicleAttribute.newBuilder()
        .setKey("on_trip").setValue("false"))  // Opaque to the Fleet Engine
    // Add .setBackToBackEnabled(true) to make this vehicle eligible for trip
    // matching while even if it is on a trip.  By default this is disabled.
    .build();

CreateVehicleRequest createVehicleRequest =
    CreateVehicleRequest.newBuilder()  // no need for the header
        .setParent(parent)
        .setVehicleId("vid-8241890")  // Vehicle ID assigned by Rideshare or Delivery Provider
        .setVehicle(vehicle)  // Initial state
        .build();

// In this case, the Vehicle is being created in the OFFLINE state and
// no initial position is being provided.  When the Driver App checks
// in with the Rideshare or Delivery Provider, the state can be set to ONLINE and
// the Driver App will update the Vehicle Location.

try {
  Vehicle createdVehicle =
      vehicleService.createVehicle(createVehicleRequest);
} catch (StatusRuntimeException e) {
  Status s = e.getStatus();
  switch (s.getCode()) {
    case ALREADY_EXISTS:
      break;
    case PERMISSION_DENIED:
      break;
  }
  return;
}
// If no Exception, Vehicle created successfully.
