Description

technical field [0001] The invention relates to the technical field of automatic control data processing, in particular to a sensing data calculation control method, a timing device and an automatic driving sensing control system. Background technique [0002] In task systems with high real-time requirements, timing services usually need to be implemented in a specific way to meet the requirements of each node for accurate, stable and reliable time parameters, so that each node of the system can coordinate actions synchronously, at a specific time point and Complete assigned tasks within time-related requirements such as deadlines. For example, in the application fields such as robots and automatic driving, in the actual application process, a large number of sensors and processors are required to coordinate to realize environmental perception and positioning, and in the process of requiring multi-sensor cooperation to complete a certain task, each sensor The time stamp inf...

Problems solved by technology

For the high incidence and real-time requirements of the timing process, some traditional timing methods such as network timing are difficult to meet

For a system that is often on the move, such as automatic driving, the long-distance timing method is often affected by the signal strength, and it is also difficult to meet the real-time timing requirements.
