Untuk performa terbaik dengan Fleet Engine, berikan aliran update lokasi kendaraan. Gunakan salah satu cara berikut untuk memberikan pembaruan ini:
Menggunakan Driver SDK: opsi paling sederhana. Lihat dokumentasi Driver SDK
untuk Android atau iOS.
Gunakan kode kustom: berguna jika lokasi diteruskan melalui backend Anda, atau jika Anda menggunakan perangkat selain Android atau iOS. Panduan ini membahas
pendekatan tersebut.
Jika tidak menggunakan Driver SDK untuk memperbarui lokasi kendaraan, Anda dapat melakukan panggilan langsung ke Fleet Engine dengan lokasi kendaraan. Untuk setiap kendaraan yang aktif,
Fleet Engine mengharapkan pembaruan lokasi setidaknya sekali setiap menit dan paling banyak
sekali setiap 5 detik. Pembaruan ini hanya memerlukan hak istimewa Fleet Engine Driver SDK User.

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)"]]
