1. A computer system for a vehicle comprising:
a sensor system of the vehicle configured to acquire a stream of signals from an environment at a sampling rate thereby providing a data stream consisting of data tokens each token corresponding to an acquired signal of the stream of signals; and
a processor of the vehicle configured to execute an algorithm for continuously acquiring the data stream consisting of data tokens, wherein the algorithm has an acquisition rate for acquiring the data tokens of the data stream;
wherein the processor of the vehicle is configured to provide instructions to the sensor system of the vehicle to adapt the sampling rate to the acquisition rate of the algorithm,
wherein the algorithm has three different states, a first status indicating that the algorithm is ready to acquire a signal of the stream of signals, a second status indicating that the algorithm is not ready to acquire a signal of the stream of signals, and a third status indicating that the algorithm is ready for acquiring a signal of the stream of signals after a time period tr has elapsed to account for acquisition latencies of the sensor system,
wherein the sensor system of the vehicle is configured to provide information to the processor on an expected acquisition time ta, the acquisition time ta indicating a time required for the sensor to acquire the signal and produce a data token based on the acquired signal,
wherein the algorithm is configured to provide information to the processor of the vehicle on a ready time when the algorithm will transition from the third status to the first status, and
wherein the processor of the vehicle is configured to read the states and to trigger the acquisition of the signal at the sensor system based on a time difference tr−ta when the algorithm is in the third status, such that the algorithm receives the data token when the algorithm enters the first status.
