为按需行程创建车辆

如需在 Fleet Engine 中为按需行程创建车辆，请使用 CreateVehicle 端点和 CreateVehicleRequest。此端点需要具有 Fleet Engine On-demand Admin 角色的账号。

按需行程车辆的字段

为按需行程创建车辆时，您必须设置必需字段。您还应熟悉某些车辆字段如何影响 Fleet Engine 中的其他功能。如需了解相关信息，请参阅更新车辆字段。

按需行程的必填字段

vehicle_state：默认值为 unknown，但应设置为 ONLINE 或 OFFLINE。如需了解如何设置车辆状态字段，请参阅更新车辆字段。
supported_trip_types：默认值为未知，但应设置为 SHARED、EXCLUSIVE 或两者兼有。如需了解详情，请参阅按需行程指南中的行程类型。
maximum_capacity：车辆可搭载的乘客人数，不包括驾驶员（根据定义）。
vehicle_type：值为 AUTO、TAXI、TRUCK、TWO_WHEELER、BICYCLE 或 PEDESTRIAN。可用于过滤车辆搜索结果中的车辆。这也会影响预计到达时间和路线计算。Fleet Engine 可根据以下车辆类型组，提供与出行方式对应的路线和行程计算结果：
- AUTO、TAXI 或 TRUCK：例如高速公路。
- TWO_WHEELER：例如，不会返回不允许两轮车的路线。
- BICYCLE：例如，自行车道。
- PEDESTRIAN：例如仅供行人通行的桥梁和人行道。

其他字段

如需了解创建车辆时可以设置的其他字段，请参阅更新车辆字段。

车辆创建示例

从 CreateVehicle 返回的值是创建的 Vehicle 实体。

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.
