But this is exactly the problem of the rover which the Audi’s quattro
drivetrain solves. It detects wheelspin on a shaft and transfers more torque to another axle, which then ensures more torque on the ground.
That’s why Audi engineers are working on optimising the Rover’s drivetrain with the Part-Time Scientists to develop an intelligent all-wheel transfer for the Audi lunar quattro.
Because, before the rover has to free itself out of a deadlocked situation on a far-away planet, the idea, of course, is to avoid such a situation from the beginning. That means: when the Audi lunar quattro explores an area with slopes and a wheel’s traction reaches its limit in moon dust, a sensor detects the threatening loss in traction. Software then regulates the drivetrain away from the wheel losing its grip and distributes it to the wheels on the axles which continue to deliver stable drive power.
In this way, the lunar quattro remains in driving order and Karsten Becker can steer it back to safe territory. Worst case averted. Mission saved.
Michael Schöffmann, Head of Transmission Development for Audi and coordinator of development with Part-Time Scientists: “The Audi quattro drivetrain is robust, instantaneous and absolutely reliable. The permanent all-wheel drive is distributed to all four wheels when the situation calls for it to completely prevent wheelspin.”
This has been the case for 35 years for cars on Earth – and now for vehicles on the moon too.
