The synchronous processing device is provided with a plurality of interfaces, each interface is connected with one subsystem, and each interface comprises a first end, a second end and a third end, wherein the first ends are used for sending synchronous base clocks, and the plurality of subsystems generate sampling clocks according to the synchronous base clocks; the second ends are used for sending collecting triggering signals to the plurality of subsystems; and the third ends are used for receiving the economic parameters sampled by the plurality of subsystems. The system ensures that sampling periods and sampling time of the plurality of subsystems are synchronous, the accuracy of the collected economic parameters is improved, the workload of subsequent data processing is reduced, and the efficiency and the reliability of data processing are improved.

Description

technical field [0001] The invention relates to the technical field of vehicles, in particular to a system for synchronously collecting economical parameters of hybrid electric vehicles and a method for synchronously collecting economical parameters of vehicles and hybrid electric vehicles. Background technique [0002] When doing economic tests on hybrid vehicles, it is not only necessary to collect information such as vehicle speed, fuel consumption and mileage during the test, but also to collect information such as the voltage and current information of the high-voltage battery in the high-voltage power system, and the torque and speed of the motor. This information is collected by different collection devices and systems, and the data to be collected in the later data analysis is synchronized. If the data collection time of a certain system is earlier or later, even if the final overall test duration is the same, Inaccurate economic analysis due to asynchronous data. T...

Problems solved by technology

[0003] In the related technology, when doing economical tests of hybrid electric vehicles, different devices are used to measure parameters, and a flag can be set artificially, such as stepping on the accelerator deeply, and each device has a symbolic pulse signal. As a signal to start collecting, but these will be limited by the state of the vehicle at that time, and will bring certain safety hazards

In other measurement schemes, synchronization can also be performed through the same signal among the signals collected by multiple devices. other signals collected by a device, however, this synchronization method depends on the experience of the analyst, and also increases the workload of data analysis, thus reducing the reliability of the data and the efficiency of data processing
