Fleet Engine의 최적 성능을 위해 차량 위치 업데이트 스트림을 제공하세요. 다음 방법 중 하나를 사용하여 이러한 업데이트를 제공하세요.
Driver SDK 사용: 가장 간단한 옵션입니다. Android 또는 iOS용 Driver SDK 문서를 참고하세요.
맞춤 코드 사용: 위치가 백엔드를 통해 중계되거나 Android 또는 iOS 이외의 기기를 사용하는 경우에 유용합니다. 이 가이드에서는 이 접근 방식을 다룹니다.
Driver SDK를 사용하여 차량 위치를 업데이트하지 않는 경우 차량 위치를 사용하여 Fleet Engine을 직접 호출할 수 있습니다. 활성 차량의 경우 Fleet Engine은 최소 1분마다 한 번, 최대 5초마다 한 번 위치 업데이트를 예상합니다. 이러한 업데이트에는 Fleet Engine Driver SDK 사용자 권한만 필요합니다.

Use either of the following ways to provide these updates:\n\n1. **Use the Driver SDK** : simplest option. See the Driver SDK documentation for [Android](/maps/documentation/mobility/driver-sdk/on-demand/android/minimum-requirements) or [iOS](//maps/documentation/mobility/driver-sdk/on-demand/ios/minimum-requirements).\n2. **Use custom code**: useful if locations are relayed through your backend, or if you use devices other than Android or iOS. This guide covers that approach.\n\nIf not using the Driver SDK to update the vehicle's location, you can make a\ndirect call to Fleet Engine with the vehicle's location. For any active vehicle,\nFleet Engine expects a location update at least once every minute and at most\nonce every 5 seconds. These updates require only *Fleet Engine Driver SDK User*\nprivileges.\n\nUpdate vehicle location example\n-------------------------------\n\n### Java\n\n static final String PROJECT_ID = \"\u003cvar translate=\"no\"\u003eproject-id\u003c/var\u003e\";\n static final String VEHICLE_ID = \"\u003cvar translate=\"no\"\u003evid-8241890\u003c/var\u003e\";\n\n VehicleServiceBlockingStub vehicleService = VehicleService.newBlockingStub(channel);\n\n String vehicleName = \"providers/\" + PROJECT_ID + \"/vehicles/\" + VEHICLE_ID;\n Vehicle updatedVehicle = Vehicle.newBuilder()\n .setLastLocation(VehicleLocation.newBuilder()\n .setSupplementalLocation(LatLng.newBuilder()\n .setLatitude(37.3382)\n .setLongitude(121.8863))\n .setSupplementalLocationTime(now())\n .setSupplementalLocationSensor(LocationSensor.CUSTOMER_SUPPLIED_LOCATION)\n .setSupplementalLocationAccuracy(DoubleValue.of(15.0))) // Optional\n .build();\n\n UpdateVehicleRequest updateVehicleRequest = UpdateVehicleRequest.newBuilder()\n .setName(vehicleName)\n .setVehicle(updatedVehicle)\n .setUpdateMask(FieldMask.newBuilder()\n .addPaths(\"last_location\"))\n .build();\n\n try {\n Vehicle updatedVehicle =\n vehicleService.updateVehicle(updateVehicleRequest);\n } catch (StatusRuntimeException e) {\n Status s = e.getStatus();\n switch (s.getCode()) {\n case NOT_FOUND:\n // Most implementations will call CreateVehicle in this case\n break;\n case PERMISSION_DENIED:\n break;\n }\n return;\n }\n // If no Exception, Vehicle updated successfully.\n\n### REST\n\n curl -X PUT \\\n \"https://fleetengine.googleapis.com/v1/providers/\u003cvar translate=\"no\"\u003eproject-id\u003c/var\u003e/vehicles/\u003cvar translate=\"no\"\u003evid-8241890\u003c/var\u003e?updateMask=last_location\" \\\n -H \"Authorization: Bearer $JWT\" \\\n -H \"Content-Type: application/json\" \\\n --data-binary @- \u003c\u003c EOM\n {\n \"supplementalLocation\": {\"latitude\": 12.1, \"longitude\": 14.5},\n \"supplementalLocationTime\": \"$(date -u --iso-8601=seconds)\",\n \"supplementalLocationSensor\": \"CUSTOMER_SUPPLIED_LOCATION\",\n \"supplementalLocationAccuracy\": 15\n }\n EOM\n\nSee [providers.vehicles.update](/maps/documentation/mobility/fleet-engine/reference/trips/rest/v1/providers.vehicles/update) reference.\n\nWhat's next\n-----------\n\n- [Get a vehicle](/maps/documentation/mobility/fleet-engine/essentials/vehicles/on-demand-get-vehicle)"]]
