Technical Field The disclosure relates to the field of autonomous driving technologies, and specifically provides a method and system for returning data on the vehicle, a controller on the vehicle, a cloud server, and a vehicle. Background Art Intelligent driving technologies such as autonomous driving technologies and auxiliary driving technologies have been favored by the majority of vehicle owners. Existing data collection methods directly set scenario data that needs to be collected and collection parameters on the vehicle when a vehicle leaves the factory. However, collection for some new scenarios can only be implemented by manufacturers through irregular upgrade and iteration of software on the vehicle. Due to little scenario data, slow data return, difficulty in algorithm iteration and the like, poor optimization of algorithms, insufficient accuracy in autonomous driving decision-making, and other problems are further caused, affecting driving experience of users. US 2021/323575 A1 discloses a data acquisition method and apparatus, which comprises: determining configuration information in response to a first input operation acting on an interface, where the configuration information includes data acquisition parameters; creating a data acquisition task in response to task creation instructions, where the configuration information in a current interface is data included in the data acquisition task; constructing and obtaining a task table according to at least one of the data acquisition tasks; and sending the task table to a vehicle terminal, where the task table is used to indicate the vehicle terminal to perform the data acquisition during a driving process of a vehicle. Accordingly, there is a need for a new solution for returning data to solve the above problem in the art. Summary The subject-matter of the present invention is defined by the features of the independent claims. Further preferred embodiments of the present invention are defined in the dependent claims.
