openpilot in simulator
=====================
openpilot implements a [bridge](bridge.py) that allows it to run in the [CARLA simulator](https://carla.org/).
## System Requirements
openpilot doesn't have any extreme hardware requirements, however CARLA requires an NVIDIA graphics card and is very resource-intensive and may not run smoothly on your system. For this case, we have a low quality mode you can activate by running:
```
./start_openpilot_docker.sh --low_quality
```
You can also check out the [CARLA python documentation](https://carla.readthedocs.io/en/latest/python_api/) to find more parameters to tune that might increase performance on your system.
## Running the simulator
First, start the CARLA server.
First, start the CARLA server in one terminal.
```
./start_carla.sh
```
Then start bridge and openpilot.
Then, start the bridge and openpilot in another terminal.
```
./start_openpilot_docker.sh
```

To see the options for changing the environment, such as the town, spawn point or precipitation, you can run `./start_openpilot_docker.sh --help`.
This will print the help output inside the docker container. You need to exit the docker container before running `./start_openpilot_docker.sh` again.
