Co-driver

Co-driver is an add-on dedicated to Assetto Corsa race simulator. It is a rally navigator software inspired by the Jemba system. If you are new to rally stage notes or Jemba, I recommend that you start with the reading of this document : http://www.jemba.se/notesUSA.htm

Co-driver is the successor of Copilot for AC app. It is comprised of two phases :

  • The reconnaissance (or "recce") recording mode : the driver must travel along the track, once, in order to record the profile of this track. This process generate automatically the pace-notes.
  • The run mode : during the race, the notes are called vocally.


A note editor is also available, allowing you to customize you pace-notes.

New features

  • The new User Interface allows the change in game of various parameters such as the audio volume or braking distance.
  • It also includes a new count down process, in accordance with FIA regulation for WRC.
  • A new pace-notes Editor is provided, making change easier and safer.

Notes optimization

  • The notes can be automatically optimized in order to follow an "ideal trajectory" given by the fast_lane.ai file when this file exists (idea due to Gigi Monticelli). In case this file is not available, an optimization is done by computation.
  • With the optimizer, the severity of corners is analyzed with a scale of twenty values (against 6 in Copilot), using the "minus" and "plus" ajustments.

Brake points

  • Co-driver generates dynamically "brake" calls : when a long flat line ends in a tightened corner, Co-driver announces the point where the brake should begin.
  • The point is calculated according to the speed of the car and can be customized using several parameters.

Customizing the notes style and language

  • The audio messages are generated by Microsoft Speech synthesizer. Thus, it is easy to add new terms in the vocabulary used to build pace-notesinn. As the messages are generated by the synthesizer, users don't have to record their own voice.
  • Languages available are : English, French, Italian and Spanish. But if you have a Microsoft Speech synthesizer installed for another language, it is possible to build a module for your own language.
  • A grammar editor make easier the modification of vocabulary, addition of comments or changes of the text of notes.
