The present invention is described in further detail below to enable those skilled in the art to practice the invention with reference to the following description.

Referring to fig. 1, fig. 1 is a schematic view of a driving data collecting device according to the present invention. In fig. 1, the driving data acquisition device in this embodiment includes a processor unit, and the processor unit is electrically connected to the ETC module and the data acquisition module respectively; the two modules are controlled separately and receive their data through this connection. The processor unit is also electrically connected with the data transmission module, and can transmit the processed data out through the data transmission module and control the data transmission module.

The data acquisition module acquires required data and transmits the data to the processor unit for processing. The data collected by the data collecting module comprises one or more of video, image, audio, geographic position and time signal, or other vehicle or driving related data. For example, the information of the vehicle-road cooperative system is intercepted and obtained, and the information related to automatic driving can be obtained. There may be more than one data acquisition module. The collected signals can also be a section class forest total.

The data acquisition module can also be connected with a vehicle bus and can acquire vehicle state parameters such as vehicle speed, tire pressure, electric quantity, temperature and the like.

In this embodiment, the vehicle has been equipped with the on-vehicle electronic tags of ETC, the utility model discloses a driving data acquisition device does not include this on-vehicle electronic tags. The ETC signal receiving module can intercept communication information between the roadside station equipment and the vehicle-mounted electronic tag, and the communication information at least comprises a vehicle identity mark. The ETC signal receiving module is generally referred to as a dedicated short-range communication signal receiver or a radio frequency receiver.

The processor unit fuses the data which at least comprise the vehicle identity identification and are received by the ETC signal receiving module and the data collected by the data collecting module.

Unlike the embodiment of fig. 1, in some embodiments, the processor unit may be understood as a processing function distributed among the modules of the driving data acquisition device, and is not necessarily a single processor chip. The processing of the data by the processor unit includes one or more of demodulation, decoding, or simple data handling.
