The match has been arranged to give Michael Carrick's side competitive action during the extended international break, with the exact date, time and location yet to be confirmed.
Manchester United have made a difficult start to the season, winning only one of their first five Premier League matches and losing two to leave them 12th in the table. They were also eliminated from the Carabao Cup by Brighton after surrendering a lead at Old Trafford.
Lausanne have experienced similar problems in Switzerland. They are bottom of the Swiss Super League after winning only one of their first nine matches.
The friendly will give Carrick an opportunity to work with his squad away from competitive pressure while a large number of players are absent on international duty.
It also brings together two clubs within Ratcliffe's football group. The British billionaire owns a minority stake in Manchester United through INEOS, while Lausanne are among the other clubs controlled by the group.
The Swiss side will also hope to benefit from the fixture as they attempt to improve a difficult start to their domestic campaign.
Both teams have won just once in their respective leagues so far, making the game an opportunity for players to gain minutes during the international break.
United's meeting with Lausanne comes before the Premier League resumes, with Carrick looking to use the period without competitive fixtures to work on his team after a disappointing opening to the campaign.
