Is the method of automatic driving maintenance platform produced by different manufacturers the same? What's the difference

Not the same; The difference lies in processing technology, data acquisition focus and so on. The methods of automatic driving maintenance platform produced by different automobile manufacturers are not exactly the same, and each manufacturer has its own R&D team and technical route. For example:

Processing technology: Tesla's Autopilot platform mainly focuses on the realization of autopilot function, and its maintenance platform also focuses on the detection and repair of autopilot-related faults. Waymo pays more attention to the maintenance of safety and reliability to ensure that its self-driving taxis can drive safely on public roads.

Pay attention to data collection: Tesla's maintenance platform mainly relies on its own vehicle data and historical experience, while Waymo pays more attention to using the data and experience provided by third parties to improve the accuracy and efficiency of its maintenance platform.
