Computer mastered parking with skidding

The car moves in reverse at a speed of about 40 km / h, then it brakes sharply, turns around 180 ° and then goes straight into the parking space, where it is theoretically impossible to drive in any other way. Many have seen such a technique in films, for example, "Taxi-2". Engineers from Stanford have developed a computer system that allows a car with autonomous control (that is, without a driver) to do this trick.



And this is not just a trick, but an important extension of the functionality of onboard control systems, which can be useful in unforeseen situations. From a scientific point of view, the most difficult thing here is to simulate the movement of a car in a controlled skidding process.

The developed program uses two models of controlled drift. The first is the default settings with a sensor-based (closed-loop) checkpoint, the second is an independent calculation of the optimal trajectory in real time (open-loop). You can also combine them to achieve the best result (multi-modal control).
