Environment: Ubuntu 16.04 Autoware 1.11.0 docker build Pacmod3 SSC

I have been trying to connect a Lexus RX 450h, which has pacmod installed, with Autoware. I have not been able to find any detailed documentation regarding this. I found the ssc_interface node and tried to run it using the steps from PR # 1945. https://github.com/autowarefoundation...

I was able to get the interface running and getting input from autoware, however, it did not seem to be communicating to either SSC or Pacmod. I don't know if I am launching pacmod in the appropriate way that allows connection with the interface, using the ssc_joystick launch file. Any help connecting with the ssc_interface or any other avenues for connecting Autoware with a vehicle would be much appreciated.

This may be due to mismatched topics. Can you please run all of your nodes (including SSC and SSC Interface) and then run the following bash script in a terminal? This will tell you which topics are being subscribed to but not published on:

for node in $(rosnode list); do rosnode info $node | grep unknown; done

I think you need to remap topics like this for your version.

  <remap from="/as/enable_cmd" to="/pacmod/as_rx/enable" />
  <remap from="/as/throttle_cmd" to="/pacmod/as_rx/accel_cmd"/>
  <remap from="/as/brake_cmd" to="/pacmod/as_rx/brake_cmd"/>
  <remap from="/as/steering_cmd" to="/pacmod/as_rx/steer_cmd"/>
  <remap from="/as/transmission_cmd" to="/pacmod/as_rx/shift_cmd"/>
  <remap from="/as/turn_signal_cmd" to="/pacmod/as_rx/turn_cmd"/>
  <remap from="/as/global_report" to="/pacmod/parsed_tx/global_rpt"/>
  <remap from="/as/throttle_report" to="/pacmod/parsed_tx/accel_rpt"/>
  <remap from="/as/brake_report" to="/pacmod/parsed_tx/brake_rpt"/>
  <remap from="/as/steering_report" to="/pacmod/parsed_tx/steer_rpt"/>
  <remap from="/as/speed" to="/pacmod/parsed_tx/vehicle_speed_rpt" />
  <remap from="/as/wheel_speed" to="/pacmod/parsed_tx/wheel_speed_rpt" />
  <remap from="/as/transmission_report" to="/pacmod/parsed_tx/shift_rpt" />

@sudip I recommend contacting AutonomouStuff as they produce the PACMod system and the SSC that @andrew-greer is talking about.

@Andrew Hi Andrew, are you using SSC software provided by the AutonomousStuff (https://autonomoustuff.com/product/as...) or is it just the autoware and the Lexus RX 450h ?
