Synchronization properties of periodic self-sustained oscillators are based on the existence of a special variable, phase \(\phi\) (see phase models). Mathematically, self-sustained oscillations correspond to a stable limit cycle in the state space of an autonomous continuous-time dynamical system. The phase \(\phi\) can be introduced as the variable parametrizing the motion along this cycle.

There are four main parts of an autonomous driving pipeline: (i) sensors, which receive environment states, (ii) perception, which uses sensor data to detect, recognizes and localizes objects around the vehicle, (iii) planning, which generates vehicle’s future.
The chain of effects in autonomous driving generally consists of different processing stages. First, the sensor’s raw data has to be preprocessed (perception). The goal is to detect features and static or dynamic objects as well as free spaces in the environment of the vehicle on the basis of single images or reflection points.
