Overview of Altran V2X RSU Apps
Altran (part of Capgemini) V2X solution enables safety & non-safety applications for V2V,V2I,V2P and V2N scenarios for Road Side Units (RSU), On Board Units (OBU) and Smart Pedestrian Devices . The solution comes with application and underlying stack conformant to regional standards - WAVE / ETSI and China. The V2X RSU Apps supports V2I use cases.
V2X Application Description
Following Vehicle To Infrastructure (V2I) applications are supported:
• Roadside Alert (RSA): RSU periodically broadcast advisory messages about the road hazards (Slippery Road, Animal On the Road etc.) • Electric Vehicle Charging Station (EVCSN): RSU periodically broadcast presence and occupancy status of nearby Electric changing station Information • Vulnerable Road User (VRU): RSU detect vulnerable road user and broadcast the same information to near-by vehicles • Time To Green (TTG) / Green Light Signal (GLOSA): RSU broadcast the traffic signals state and time information to near-by vehicles in an intersection
Separate container images are provided for OBU / RSU apps which can be onboarded (as pods) and communicate over UDP/IP interface. A Human Machine Interface (HMI) app is provided for visualization and demo purpose. In real deployment scenario the UDP/IP interface could be replaced by C-V2X PC5 or C-V2X Uu air interface
Pre Requisites
•Cluster with minimum 1 Master and 1 Slave. (Recommended 2-Slaves and 1-Master) •Altran provided container images for V2X RSU/OBU Apps
Note: Air interface integration requires third party radio integration for C-V2X PC5 interface and MNO application server for C-V2X Uu interface
Usage
Repository
The Altran V2X application is available in the Altran provided shareable repository upon request. Please contact Altran sales for details
Install Altran V2X Applications
From the Controller Node, go to helm chart folder of the repository:
$ helm install altran < image provided by Altran sales > --set service.type=NodePort
Show helm is installed
$helm get all altran
Execute the python web server for HMI demonstration
$ cd <WaveHmi>
$ python websock_server.py -i<ip_address> -t80 -p<port_number>
$kubectl get pods -o wide
Get all three pods(pod name starts with v2xstack-xxx-xxx) IP address for inter-communication between the pods, then update config
After helm Install we need to change the config file of each pods as Host Vehicle, Remote Vehicle and RSU.
$ kubectl exec –stdin –tty <podname> -- /bin/bash
| Safety.conf for HV | Safety.conf for RV | Safety.conf for RSU |
|---|---|---|
| obu_id=1 | obu_id=2 | obu_id=3 |
| speed=150 | speed=100 | vru_rsu=1 |
| host_vehicle=1 | host_vehicle=0 | rsa_rsu=1 |
| svw_simulation=1 | svw_simulation=1 | ts_rsu=1 |
| evcsn_simulation=1 | evcsn_simulation=1 | Map=1 |
| Vru_rx=1 | ts_rx=1 | evcsn_rsu=1 |
| Ts_rx=1 | host_vehicle=0 | |
| Rsa_rx=1 |
Update the dynamic IP Address :
Web_server_port= <ip address of controller> at HV (host Vehicle) safety.conf
Intercommunication IP addresses update:
hv_udp_port=9081 #host vehicle UDP port,will get used when UDP adaption is enabled
hv_ipaddr=<1st pod’s IP address >
rv_udp_port=9080 #remote vehicle UDP port,will get used when UDP adaption is enabled
rv_ipaddr=<2nd pod’s IP address >
rsu_udp_port=9082 #rsu UDP port,will get used when UDP adaption is enabled
rsu_ipaddr=<3rdt pod’s IP address >
To execute the stack binary , export the library path by using the below command
$ export LD_LIBRARY_PATH=./lib
Execute each binary
$./v2xsafetyapp &
Test Output
helm uninstall v2xstack
