Problems solved by technology
However, the conditions that trigger data recording during the activation of the automatic driving system and / or assisted driving system are more dangerous, such as the moment when the air bag is deployed, the moment when the vehicle is driven by a large yaw rate, the moment when the pedestrian protection device is triggered, etc., so It is difficult to implement the above-mentioned scenarios in the vehicle test, even if the above-mentioned scenarios are traversed to a certain extent, it is difficult to ensure the safety of personnel and vehicles

The invention relates to a method for testing a data storage system. The method comprises the following steps: a simulation module sends a signal to a control module related to the automobile event data storage system and a control unit of the data storage system, wherein the signal comprises information for keeping the control module and the control unit in a working preparation state and information of data required to be recorded (S1); operating the test device so that the control module triggers the data recording and triggers the control module to send a signal related to the collision event to the control unit for triggering the control unit to store data based on the information of the data required to be recorded (S2); data stored in the control unit is acquired and checked (S3). The invention also relates to an apparatus for testing a data storage system and a computer program product performing the method. According to the embodiment of the invention, standardized unified testing can be carried out on data storage systems of intelligent networked vehicles which are produced by different automobile manufacturers and have an automatic driving function.
Description
technical field [0001] The present invention relates to the technical field of vehicle testing, in particular to a method for testing a data storage system, a device for testing a data storage system and a computer program product for executing the method. Background technique [0002] For intelligent and connected vehicles with high-level driving assistance and / or autonomous driving functions, the requirements related to the data storage system are gradually being standardized to meet potential management requirements such as accident determination and accident scene recurrence. At the same time, domain controllers are increasingly used because of their service-oriented, centralized architecture divided by function, which can not only accelerate the separation of software and hardware, but also save the cost of the whole machine. Many automobile manufacturers integrate data storage systems in domain controllers. On the one hand, this architecture enables the data storage sy...
