Overtake Assistant

Experimental third-party ETS2LA plugin that coordinates overtaking by using the existing indicator lane-change flow. It does not modify Pathfinding, Lane Assist, or Adaptive Cruise Control.

Current behavior

• Registers a Toggle Overtake Assistant control.
• Listens to game telemetry and traffic data.
• When enabled, looks for a slower vehicle 10-85 meters ahead in the current lane.
• If the truck is at least 5 km/h faster and the adjacent left lane appears clear, sends a short lblinker pulse through GameOutput.
• After passing the original target vehicle, sends a short rblinker pulse to request returning once the right lane is clear 70 meters ahead and 35 meters behind.
• After completion or abort, waits 10 seconds before checking for another overtake.
• Registers an ETS2LA overlay window with live status, target distance, speed delta, cooldown, and lane-clear checks.
• Registers optional AR markers that draw the current candidate or active target vehicle in the game overlay. During passing/returning it also draws the right lane return-clearance zone.
• Adjacent-lane safety checks scan the requested side only and include a vehicle-size buffer.

The actual lane-change execution remains owned by the existing Pathfinding, Lane Assist, and ACC plugins.

The overlay window and AR markers can be toggled from the plugin settings page.

Build

From the workspace root:

$env:APPDATA = (Resolve-Path .).Path + '\.dotnet-appdata'
$env:DOTNET_CLI_HOME = (Resolve-Path .).Path + '\.dotnet-home'
$env:NUGET_PACKAGES = (Resolve-Path .).Path + '\.nuget-packages'
dotnet restore ThirdPartyPlugins\OvertakeAssistant\OvertakeAssistant.csproj --configfile ThirdPartyPlugins\OvertakeAssistant\NuGet.config
dotnet build ThirdPartyPlugins\OvertakeAssistant\OvertakeAssistant.csproj -c Release

Install

Copy the built DLL to the portable release plugin directory. Manually installed plugins must currently be placed directly under Plugins/; subfolders are only used by manifest-installed plugins.

Copy-Item ThirdPartyPlugins\OvertakeAssistant\bin\Release\net10.0\OvertakeAssistant.dll Release-ETS2LA-win-beta-Portable\current\Plugins\OvertakeAssistant.dll

Then restart ETS2LA, enable the plugin, bind Toggle Overtake Assistant, and turn it on only after Pathfinding, Lane Assist, and ACC are already working.

Safety limits

This first version is intentionally conservative and should be treated as a closed-course prototype:

• It only requests one lane change via indicators.
• It cancels on paused assists, paused game, low speed, or manual brake/steer input during an overtake.
• It uses traffic positions and estimated truck heading only; it does not yet inspect road topology, lane legality, upcoming ramps, junctions, or road signs.
